PROASSURANCE CORP – 10-K – MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Edgar Glimpses
The following discussion generally focuses on the change in financial condition,
results of operation and cash flows for the year ended December 31, 2021 as
compared to the year ended December 31, 2020 and should be read in conjunction
with the Consolidated Financial Statements and Notes to those statements which
accompany this report. For a full discussion of the changes in the financial
condition, results of operations and cash flows for the year ended December 31,
2020 as compared to the year ended December 31, 2019, please refer to Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" section of ProAssurance's December 31, 2020 report on Form 10-K.

Throughout the discussion we use certain terms and abbreviations, which can be
found in the Glossary of Terms and Acronyms at the beginning of this report. In
addition, a glossary of insurance terms and phrases is available on the investor
section of our website. Throughout the discussion, references to "ProAssurance,"
"PRA," "Company," "organization," "we," "us" and "our" refer to ProAssurance
Corporation and its consolidated subsidiaries. The discussion contains certain
forward-looking information that involves significant risks, assumptions and
uncertainties. As discussed under the heading "Caution Regarding Forward-Looking
Statements," our actual financial condition and results of operations could
differ significantly from these forward-looking statements.

ProAssurance Overview


ProAssurance Corporation is a holding company for property and casualty
insurance companies. Our wholly owned insurance subsidiaries provide
professional liability insurance, liability insurance for medical technology and
life sciences risks and workers' compensation insurance. We also provide capital
to Syndicate 1729 at Lloyd's of London.

We operate in five segments which are based on our internal management reporting
structure for which financial results are regularly evaluated by our CODM to
determine resource allocation and assess operating performance. Descriptions of
ProAssurance's five operating and reportable segments are as follows:

•Specialty P&C - This segment includes our professional liability business and
medical technology liability business. Our professional liability insurance is
primarily comprised of medical professional liability products offered to
healthcare providers and institutions and includes the business acquired through
the NORCAL transaction that closed on May 5, 2021. To a lesser extent, we also
offer professional liability insurance to attorneys and their firms. Medical
technology liability insurance is offered to medical technology and life
sciences companies that manufacture or distribute products including entities
conducting human clinical trials. We also offer custom alternative risk
solutions including loss portfolio transfers, assumed reinsurance and captive
cell programs for healthcare professional liability insureds. For our
alternative market captive cell programs, we cede either all or a portion of the
premium to certain SPCs in our Segregated Portfolio Cell Reinsurance segment.

•Workers' Compensation Insurance - This segment includes our workers'
compensation insurance business which is provided primarily to employers with
1,000 or fewer employees. Our workers' compensation products include guaranteed
cost policies, policyholder dividend policies, retrospectively-rated policies,
deductible policies and alternative market solutions. Alternative market program
premiums are 100% ceded to either SPCs in our Segregated Portfolio Cell
Reinsurance segment or, to a limited extent, an unaffiliated captive insurer.

•Segregated Portfolio Cell Reinsurance - This segment includes the results
(underwriting profit or loss, plus investment results, net of U.S. federal
income taxes) of SPCs at Inova Re and Eastern Re, our Cayman Islands SPC
operations. Each SPC is owned, fully or in part, by an individual company,
agency, group or association, and the results of the SPCs are attributable to
the participants of that cell. We participate to a varying degree in the results
of selected SPCs and, for the SPCs in which we participate, our participation
interest ranges from a low of 20% to a high of 85%. SPC results attributable to
external cell participants are reflected as an SPC dividend expense (income) in
our Segregated Portfolio Cell Reinsurance segment. The SPCs assume workers'
compensation insurance, healthcare professional liability insurance or a
combination of the two from our Workers' Compensation Insurance and Specialty
P&C segments.

•Lloyd's Syndicates - This segment includes the results from our participation
in Lloyd's of London Syndicate 1729 (5% for the 2021 underwriting year) and
Syndicate 6131 (50% for the 2021 underwriting year). The results of this segment
are normally reported on a quarter lag, except when information is available
that is material to the current period. Syndicate 1729 underwrites risks over a
wide range of property and casualty insurance and reinsurance lines in both the
U.S. and international markets. Effective January 1, 2022, Syndicate 6131 ceased
underwriting on a quota share basis with Syndicate 1729 as Syndicate 6131's
business is retained within Syndicate 1729 beginning with the 2022 underwriting
year. Premium from our participation in the results of Syndicate 6131 from open
underwriting years prior to 2022 will continue to earn out pro rata over the
entire policy period of the underlying business. Prior to January 1, 2022,
Syndicate 6131 was an SPA which focused on contingency and specialty

                                       40

property business. For the 2022 underwriting year, our participation in the
results of Syndicate 1729 remains unchanged at 5%.


•Corporate - This segment includes our investment operations, including the
investment operations of NORCAL since the date of acquisition and excludes those
reported in our Segregated Portfolio Cell Reinsurance and Lloyd's Syndicates
segments. In addition, this segment includes corporate expenses, interest
expense, U.S. income taxes and non-premium revenues generated outside of our
insurance entities.

Additional information regarding our segments is included in Note 19 of the
Notes to Consolidated Financial Statements, Part I and in the Segment Results
sections that follow.

Growth Opportunities and Outlook


Over the long-term we expect our growth to come primarily through controlled
expansion of our existing operations. In addition, we may identify opportunities
for growth through the acquisition of other insurers, service providers or books
of business. On May 5, 2021, we completed our acquisition of NORCAL Insurance
Company. The addition of NORCAL broadens our geographic reach allowing us to
create a truly national platform for our Healthcare Professional Liability
Business. Through this greater scale, we believe we can create operating
efficiencies and increase our product offerings that will allow us to deliver
value to our customers, business partners and other stakeholders. See further
discussion on the NORCAL acquisition in Note 2 of the Notes to Consolidated
Financial Statements and under the heading "Business Combinations and Ventures"
in the Liquidity and Capital Resources and Financial Condition section that
follows. We continue to see new opportunities from each of our acquisitions and
believe each will provide organic growth through expansion in their existing
markets and relationships.

We operate in very competitive markets and face strong competition from other
insurance companies for all of our insurance products. Our Specialty P&C segment
includes our HCPL insurance which represents the largest product line in our
consolidated gross premiums written (51% in 2021). The Specialty P&C segment
also includes our Medical Technology Liability (4% in 2021) and Small Business
Unit (11% in 2021) lines of business. The healthcare market in the U.S. is
continuing to consolidate, which brings competitive challenges. This
consolidation initially took the form of hospitals acquiring physician practices
and later the growth of physician groups owned by outside investors. As these
trends continue most physicians no longer practice medicine as owners of an
independent practice. Large single and multi-specialty practices often operate
in many states. Healthcare delivery settings are changing with the growth of
retail delivery by allied healthcare professionals as well as physicians in
distributed clinics, pharmacies, large consumer stores and online. These larger
commercial enterprises have differing risk management needs from those in the
traditional small physician practices. In response to these trends, we have
enhanced our coverage offerings to fit the needs of combined hospital/physician
entities, multi-state medical groups, telemedicine companies, miscellaneous
facilities, allied healthcare professionals and self-insured entities even as we
continue to service that portion of the market maintaining more traditional
practice structures. Our Medical Technology Liability and Small Business Unit
lines of business are less affected by these consolidation trends.

Our operations at Eastern, a provider of workers' compensation insurance,
represents the second largest product line in our consolidated gross premiums
written (25% in 2021, including alternative market premiums). The workers'
compensation market is highly competitive in our operating territories and
multi-line insurers continue to leverage workers' compensation in their product
offerings, which has resulted in a reduction of new business writings. We
believe our workers' compensation product offerings allow us to provide
flexibility in offering solutions to our customers at a competitive price. In
addition, we believe that our claims handling and risk management services are
attractive to our customers and provide us with a competitive advantage even
when our pricing is higher than our competitors, which has contributed to strong
renewal retention.

Our Lloyd's Syndicates segment represents 4% of our consolidated gross premiums
written in 2021. Effective January 1, 2022, Syndicate 6131 ceased underwriting
on a quota share basis with Syndicate 1729 as Syndicate 6131's business is
retained within Syndicate 1729 beginning with the 2022 underwriting year. Our
participation in Syndicate 1729 for the 2014 through 2021 underwriting years has
ranged from a low of 5% to a high of 62%. For the 2022 underwriting year, our
participation in the results of Syndicate 1729 remains unchanged at 5%. Our
participation in Syndicate 6131 ranged from a low of 50% to a high of 100% for
the 2018 through 2021 underwriting years.

We believe our emphasis on the fair treatment of our insureds and other
important stakeholders through our commitment to "Treated Fairly" has enhanced
our market position and differentiated us from other insurers. We will continue
to uphold our values of integrity, leadership, relationships and enthusiasm in
all of our activities. We will honor these values in the execution of "Treated
Fairly" to perform our Mission and realize our Vision. We believe that as we
reach more customers with this message we will continue to improve retention and
add new insureds.

Key Performance Measures


We are committed to disciplined underwriting, pricing and loss reserving
practices as well as conservative investment practices, even during difficult
market conditions. We are also committed to maintaining prudent operating and
financial leverage. We recognize the importance that our customers and producers
place on the financial strength of our insurance subsidiaries, and we manage our
business to protect our financial security.

In evaluating our performance, we consider a number of performance measures,
including the following:


•The net loss ratio which is calculated as net losses and loss adjustment
expenses incurred divided by net premiums earned and is a component of
underwriting profitability.
•The underwriting expense ratio which is calculated as underwriting, policy
acquisition and operating expenses incurred divided by net premiums earned and
is a component of underwriting profitability.
•The combined ratio which is the sum of the net loss ratio and the underwriting
expense ratio and measures underwriting profitability.
•The investment income ratio which is calculated as net investment income
divided by net premiums earned and measures the contribution investment earnings
provide to our overall profitability.
•The operating ratio which is the combined ratio, less the investment income
ratio. This ratio provides the combined effect of underwriting profitability and
investment income.
•The tax ratio which is calculated as total income tax expense (benefit) divided
by income (loss) before income taxes and measures our effective tax rate.
•ROE which is calculated as net income (loss) divided by the average of
beginning and ending shareholders' equity. This ratio measures our overall
after-tax profitability and shows how efficiently capital is being used.
•Book value per share which is calculated as total shareholders' equity at the
balance sheet date divided by the total number of common shares outstanding.
This ratio measures the net worth of the Company to shareholders on a per-share
basis. The declaration of dividends decreases book value per share. Growth in
book value per share, adjusted for dividends declared, is an indicator of
overall profitability.

In particular, we focus on our combined ratio and investment returns, both of
which directly affect our ROE and growth in our book value. Currently, we target
a dynamic long-term ROE of 700 basis points above the 10-year U.S. Treasury
rate, which at December 31, 2021 was approximately 8.5%.

To achieve our long-term ROE target, we emphasize rate adequacy, selective
underwriting, effective claims management, operational efficiency gained by
leveraging our enhanced scope and scale and prudent investment management. We
closely monitor premium revenues, losses and loss adjustment expenses, and
underwriting and policy acquisition expenses. Our overall investment strategy is
to focus on maximizing current income from our investment portfolio while
maintaining appropriate credit risk, liquidity, duration, portfolio
diversification and capital efficiency. While we engage in activities that
generate other income, these activities, such as insurance agency services, do
not constitute a significant use of our resources or a significant source of
revenues or profits.

Critical Accounting Estimates


Our Consolidated Financial Statements are prepared in conformity with GAAP.
Preparation of these financial statements requires us to make estimates and
assumptions that affect the amounts we report on those statements. We evaluate
these estimates and assumptions on an ongoing basis based on current and
historical developments, market conditions, industry trends and other
information that we believe to be reasonable under the circumstances, including
the potential impacts of the COVID-19 pandemic (see "Item 1A, Risk Factors"
included in this report for additional information). We can make no assurance
that actual results will conform to our estimates and assumptions; reported
results of operations may be materially affected by changes in these estimates
and assumptions.

Management considers the following accounting estimates to be critical because
they involve significant judgment by management and those judgments could result
in a material effect on our financial statements.

Reserve for Losses and Loss Adjustment Expenses


The largest component of our liabilities is our reserve for losses and loss
adjustment expenses ("reserve for losses" or "reserve"), and the largest
component of expense for our operations is incurred losses and loss adjustment
expenses (also referred to as "losses and loss adjustment expenses," "incurred
losses," "losses incurred" and "losses"). Incurred losses reported in any period
reflect our estimate of losses incurred related to the premiums earned in that
period as well as any changes to our previous estimate of the reserve required
for prior periods.

As of December 31, 2021, our reserve is comprised almost entirely of long-tail
exposures. The estimation of long-tailed losses is inherently difficult and is
subject to significant judgment on the part of management. Due to the nature of
our claims, our loss costs, even for claims with similar characteristics, can
vary significantly depending upon many factors, including but not limited to the
specific characteristics of the claim and the manner in which the claim is
resolved. Long-tailed insurance is characterized by the extended period of time
typically required both to assess the viability of a claim and potential
damages, if any, and to reach a resolution of the claim. The claims resolution
process may extend to more than five years. The combination of continually
changing conditions and the extended time required for claim resolution results
in a loss cost estimation process that requires actuarial skill and the
application of significant judgment, and such estimates require periodic
modification.

Our reserve is established by management after taking into consideration a
variety of factors including premium rates, historical paid and incurred loss
development trends and our evaluation of the current loss environment including
frequency, severity, expected effect of inflation, general economic and social
trends, and the legal and political environment. We also take into consideration
the conclusions reached by our internal and consulting actuaries. We update and
review the data underlying the estimation of our reserve for losses each
reporting period and make adjustments to loss estimation assumptions that we
believe best reflect emerging data. Both our internal and consulting actuaries
perform an in-depth review of our reserve for losses on at least a semi-annual
basis using the loss and exposure data of our insurance subsidiaries.

We partition our reserves by accident year, which is the year in which the claim
becomes our liability. For claims-made policies, the insured event generally
becomes a liability when the event is first reported to us. For occurrence
policies, the insured event becomes a liability when the event takes place. For
retroactive coverages, the insured event becomes a liability at inception of the
underlying contract. As claims are incurred (reported) and claim payments are
made, they are aggregated by accident year for analysis purposes. We also
partition our reserves by reserve type: case reserves and IBNR reserves. Case
reserves are established by our claims departments based upon the particular
circumstances of each reported claim and represent our estimate of the future
loss costs (often referred to as expected losses) that will be paid on reported
claims. Case reserves are decremented as claim payments are made and are
periodically adjusted upward or downward as estimates regarding the amount of
future losses are revised; reported loss for an individual claim is the case
reserve at any point in time plus the claim payments that have been made to
date. IBNR reserves are estimated by accident year and represent our estimate in
the aggregate of future development on losses that have been reported to us and
our estimate of losses that have been incurred but not reported to us.

Our reserving process can be broadly grouped into three areas: the establishment
of the reserve for the current accident year (the initial reserve), the
re-estimation of the reserve for prior accident years (development of prior
accident years) and the establishment of the initial reserve for risks assumed
in business combinations, applicable only in periods in which acquisitions occur
(the acquired reserve). A summary of the activity in our net reserve for losses
during 2021 and 2020 is provided under the heading "Losses" in the Liquidity and
Capital Resources and Financial Condition section that follows.

Current Accident Year - Initial Reserve


Considerable judgment is required in establishing our initial reserve for any
current accident year period, as there is limited data available upon which to
base our estimate (see further discussion that follows under the heading "Use of
Judgment"). Our process for setting an initial reserve considers the unique
characteristics of each product, but in general we rely heavily on the loss
assumptions that were used to price business, as our pricing reflects our
analysis of loss costs that we expect to incur relative to the insurance product
being priced.

                                       43

Specialty P&C Segment. Loss costs within this segment are impacted by many
factors including but not limited to the nature of the claim, including whether
or not the claim is an individual or a mass tort claim, the personal situation
of the claimant or the claimant's family, the outcome of jury trials, the
legislative and judicial climate where any potential litigation may occur,
general economic and social trends and, for claims involving bodily injury, the
trend of healthcare costs. Within our Specialty P&C segment, for our
professional liability business (88% of our consolidated gross reserve for
losses and loss adjustment expenses as of December 31, 2021; predominately
comprised of our HCPL products), we set an initial reserve based upon our
evaluation of the current loss environment including frequency, severity,
economic inflation, social inflation and legal trends.

The current accident year net loss ratio in the Specialty P&C segment has ranged
from 87% to 106% in recent years, excluding the effect of a single large
national healthcare account that generated outsized losses and distorted results
for 2019 and 2020. We observed a reduction in claims frequency in 2020 that
continued into 2021, some of which is due to our re-underwriting efforts while
some of which we believe is associated with the COVID-19 pandemic including the
disruption of the court systems. Given the consistent and prolonged nature of
these favorable trends, we recognized some of these favorable frequency trends
in our HCPL current accident year reserve during the third and fourth quarters
of 2021. We continue to remain cautious in recognizing the full impact of these
favorable trends due to the long-tailed nature of our HCPL claims as well as the
uncertainty surrounding the length and severity of the pandemic. See further
discussion in our Segment Results - Specialty Property & Casualty section that
follows under the heading "Losses and Loss Adjustment Expenses."

The risks insured in our Medical Technology Liability business (2% of our
consolidated gross reserve for losses and loss adjustment expenses as of
December 31, 2021) are more varied, and policies are individually priced based
on the risk characteristics of the policy and the account. The insured risks
range from startup operations to large multinational entities, and the larger
entities often have significant deductibles or self-insured retentions. Reserves
are established using our most recently developed actuarial estimates of losses
expected to be incurred based on factors which include results from prior
analysis of similar business, industry indications, observed trends and
judgment. Claims in this line of business primarily involve bodily injury to
individuals and are affected by factors similar to those of our HCPL line of
business. For the Medical Technology Liability business, we also establish an
initial reserve using a loss ratio approach, including a provision in
consideration of historical loss volatility that this line of business has
exhibited.

Workers' Compensation Insurance Segment. Many factors affect the ultimate losses
incurred for our workers' compensation coverages (5% of our consolidated gross
reserve for losses and loss adjustment expenses as of December 31, 2021)
including but not limited to the type and severity of the injury, the age,
health and occupation of the injured worker, the estimated length of disability,
medical treatment and related costs, and the jurisdiction and workers'
compensation laws of the state of the injury occurrence.

We use various actuarial methodologies in developing our workers' compensation
reserve, combined with a review of the payroll exposure base. For the current
accident year, given the lack of seasoned information, the different actuarial
methodologies produce results with significant variability; therefore, more
emphasis is placed on supplementing results from the actuarial methodologies
with trends in exposure base, medical expense inflation, general inflation,
severity, and claim counts, among other things, to select an ultimate loss
indication.

As in our Specialty P&C segment, we observed a reduction in claims frequency in
2020. Claims frequency in 2021 continues to be below pre-pandemic levels in our
Workers' Compensation Insurance segment, some of which is likely associated with
the COVID-19 pandemic. While claims frequency is down, we have experienced an
increase in 2021 accident year reported losses through December 31, 2021,
including increased severity-related claim activity, reflecting workers
returning to full employment in 2021 after the lifting of pandemic-related
restrictions and the labor shortage. The increase in reported claim activity is
attributable to workers being out of "work shape" as they returned to employment
in 2021 as well as the lack of training, alternative work arrangements and
employee fatigue due to the labor shortage.

Segregated Portfolio Cell Reinsurance Segment. The factors that affect the
ultimate losses incurred for the workers' compensation and HCPL coverages
assumed by the SPCs at Inova Re and Eastern Re (2% of our consolidated gross
reserve for losses and loss adjustment expenses as of December 31, 2021) are
consistent with that of our Workers' Compensation Insurance and Specialty P&C
segments, respectively.

Lloyd's Syndicates Segment. Initial reserves for Syndicate 1729 and Syndicate
6131 are primarily recorded using the loss assumptions by risk category
incorporated into each Syndicate's business plan submitted to Lloyd's with
consideration given to loss experience incurred to date (3% of our consolidated
gross reserve for losses and loss adjustment expenses as of December 31, 2021).
The assumptions used in each business plan are consistent with loss results
reflected in Lloyd's historical data for similar risks. The loss ratios may also
fluctuate due to the mix of earned premium from different open underwriting
years which we participate in to varying degrees, as well as the timing of
earned premium adjustments. Such adjustments may be the result of premiums for
certain policies and assumed reinsurance contracts being reported subsequent to
the coverage period and may be subject to adjustment based on loss experience.
Premium and exposure for some of Syndicate 1729's insurance policies and
reinsurance contracts are initially estimated and subsequently recorded over an
extended period of time

                                       44

--------------------------------------------------------------------------------

as reports are received under delegated underwriting authority programs. When
reports are received, the premium, exposure and corresponding loss estimates are
revised accordingly. Changes in loss estimates due to premium or exposure
fluctuations are incurred in the accident year in which the premium is earned.

For significant property catastrophe exposures, Syndicate 1729 uses third-party
catastrophe models to accumulate a listing of potentially affected policies.
Each identified policy is given an estimate of loss severity based upon a
combination of factors including the probable maximum loss of each policy,
market share analytics, underwriting judgment, client/broker estimates and
historical loss trends for similar events. These models are inherently
uncertain, reliant upon key assumptions and management judgment and are not
always a representation of actual events and ensuing potential loss exposure.
Determination of actual losses may take an extended period of time until claims
are reported and resolved, including coverage litigation.

Development of Prior Accident Years

In addition to setting the initial reserve for the current accident year, we
reassess the amount of reserve required for prior accident years each period.


The foundation of our reserve re-estimation process is an actuarial analysis
that is performed by both our internal and consulting actuaries. This very
detailed analysis projects ultimate losses based on partitions which include
line of business, geography, coverage layer and accident year. The procedure
uses the most representative data for each partition, capturing its unique
patterns of development and trends. We believe that the use of consulting
actuaries provides an independent view of our loss data as well as a broader
perspective on industry loss trends.

For the Specialty P&C, Workers' Compensation Insurance and Segregated Portfolio
Cell Reinsurance segments, the analysis performed by the consulting actuaries
analyzes each partition of our business in a variety of ways and uses multiple
actuarial methodologies in performing these analyses, including:

•Bornhuetter-Ferguson (Paid and Reported) Method
•Paid Development Method
•Reported (Incurred) Development Method
•Average Paid Value Method
•Average Reported Value Method

A brief description of each method follows.


Bornhuetter-Ferguson Method. We use both the Paid and the Reported
Bornhuetter-Ferguson Methods. The Paid Method assigns partial weight to initial
expected losses for each accident year (initial expected losses being the first
established case and IBNR reserves for a specific accident year) and partial
weight to paid to date losses. The Reported Method assigns partial weight to the
initial expected losses and partial weight to current expected losses. The
weights assigned to the initial expected losses decrease as the accident year
matures.

Paid Development and Reported (Incurred) Development Methods. These methods use
historical, cumulative losses (paid losses for the Paid Development Method,
reported losses for the Reported (Incurred) Development Method) by accident year
and develop those actual losses to estimated ultimate losses based upon the
assumption that each accident year will develop to estimated ultimate cost in a
manner that is analogous to prior years, adjusted as deemed appropriate for the
expected effects of known changes in the claim payment environment (and case
reserving environment for the Reported (Incurred) Development Method); and to
the extent necessary, supplemented by analyses of the development of broader
industry data.

Average Paid Value and Average Reported Value Methods. In these methods, average
claim cost data (paid claim cost for the Average Paid Value Method and reported
claim cost for the Reported Value Method) is developed to an ultimate average
cost level by report year based on historical data. Claim counts are similarly
developed to an ultimate count level. The average claim cost (after rounding and
adjustment, if necessary, to accommodate report year data that is not considered
to be predictive) is then multiplied by the ultimate claim counts by report year
to derive ultimate loss and ALAE.

Generally, methods such as the Bornhuetter-Ferguson Method are used on more
recent accident years where we have less data on which to base our analysis. As
time progresses and we have an increased amount of data for a given accident
year, we begin to give more confidence to the development and average methods,
as these methods typically rely more heavily on our own historical data. These
methods emphasize different aspects of loss reserve estimation and provide a
variety of perspectives for our decisions.

Certain of the methodologies utilized to estimate the ultimate losses for each
partition of our reserves consider the actual amounts paid. Paid data is
particularly influential when a large portion of known claims have been closed,
as is the case for older accident years. In selecting a point estimate for each
partition, management considers the extent to which trends are emerging
consistently for all partitions and known industry trends. Thus, actual, rather
than estimated severity trends are given more consideration. If actual severity
trends are lower than those estimated at the time that reserves were previously

                                       45

--------------------------------------------------------------------------------

Table of Contents

established, the recognition of favorable development is indicated. This is
particularly true for older accident years where our actuarial methodologies
give more weight to actual loss costs (severity).


The various actuarial methods discussed above are applied in a consistent manner
from period to period. In addition, we perform statistical reviews of claims
data such as claim counts, average settlement costs and severity trends when
establishing our reserves.

We utilize the selected point estimates of ultimate losses to develop estimates
of ultimate losses recoverable from reinsurers, based on the terms and
conditions of our reinsurance agreements. An overall estimate of the amount
receivable from reinsurers is determined by combining the individual estimates.
Our net reserve estimate is the gross reserve point estimate less the estimated
reinsurance recovery.

For our Workers' Compensation Insurance segment and for the workers'
compensation exposures in our Segregated Portfolio Cell Reinsurance segment, we
utilize the Reported (Incurred) Development Method, Paid Development Method and
Bornhuetter-Ferguson Method, to develop our reserve for each accident year. The
actuarial review includes the stratification of claims data (lost time claims,
medical only claims) using different variations that allow us to identify trends
that may not be readily identifiable if the data was evaluated only in the
aggregate. Reported and paid loss development factors are key assumptions in the
reserve estimation process and are based on our historical reported and paid
loss development patterns. As accident years mature, the various actuarial
methodologies produce more consistent loss estimates.

For our Lloyd's Syndicates segment we rely on the analysis of actual loss
experience on the book of business written by Syndicate 1729 to determine loss
development by accident year.


Acquired Reserve

The acquisition of NORCAL increased our gross reserves by $1.2 billion which was
the fair value of NORCAL's gross loss reserve at the time of acquisition. The
fair value estimate of NORCAL's gross reserve for losses and loss adjustment
expenses was based on three components: an actuarial estimate of the expected
future net cash flows, a reduction to those cash flows for the time value of
money determined utilizing the U.S. Treasury Yield Curve and a risk margin
adjustment to reflect the net present value of profit that an investor would
demand in return for the assumption of the development risk associated with the
reserve. The fair value of NORCAL's gross reserve, including the risk margin
adjustment, exceeded the actuarial estimate of NORCAL's undiscounted gross loss
reserve by approximately $42.2 million as of May 5, 2021. This fair value
adjustment was recorded to the reserve for losses and loss adjustment expenses
and will be amortized over a period utilizing loss payment patterns as a
reduction to prior accident year net losses and loss adjustment expenses. We
also recorded other adjustments to NORCAL's reserve as a result of purchase
accounting including negative VOBA on NORCAL's assumed unearned premium and
assumed DDR reserve. See further discussion on these other purchase accounting
adjustments in this section under the heading "Business Combinations" or in Note
2 of the Notes to Consolidated Financial Statements for more information.

The acquisition of Eastern on January 1, 2014 increased our loss reserve by
$153.2 million which represented the fair value of Eastern's loss reserve at the
time of the acquisition. The fair value of the reserve for losses and loss
adjustment expenses and related reinsurance recoverables was based on an
actuarial estimate of the expected future net cash flows, a reduction of those
cash flows for the time value of money determined utilizing the U.S. Treasury
Yield Curve, and a risk adjustment to reflect the net present value of profit
that an investor would demand in return for the assumption of the associated
risks. Expected net cash flows were derived from the expected loss payment
patterns included in an actuarial analysis of Eastern's reserve performed as of
December 31, 2013. The fair value of the reserve, including the risk margin
discussed above, exceeded the undiscounted loss reserve previously established
by Eastern by $9.3 million; this fair value adjustment was amortized over the
average expected life of the reserve of 6 years. The fair value adjustment was
fully amortized as of December 31, 2019.

Use of Judgment


The process of estimating reserves involves a high degree of judgment and is
subject to a number of variables. These variables can be affected by both views
of internal and external events, such as changes in views of economic inflation,
legal trends and legislative changes, as well as differentiating views of
individuals involved in the reserve estimation process, among others. We
continually refine our estimates in a regular, ongoing process as historical
loss experience develops and additional claims are reported and settled. Our
objective is to consider all significant facts and circumstances known at the
time.

Changes in economic conditions and steps taken by the federal government and the
Federal Reserve in response to COVID-19 could lead to inflation trends that are
different from those we anticipated when establishing our reserves, which could
in turn lead to an increase or decrease in our loss costs and the need to
strengthen or reduce reserves.

We use various actuarial methods in the process of setting reserves. Each
actuarial method generally returns a different value, and for the more recent
accident years the variations among the various methodologies can be
significant. In order to


                                       46

--------------------------------------------------------------------------------

Table of Contents


project ultimate losses, we partition our reserves for analysis such as by line
of business, geography, coverage layer or accident year. For each partition of
our reserves, we evaluate the results of the various methods, along with the
supplementary statistical data regarding such factors as closed with and without
indemnity ratios, claim severity trends, the expected duration of such trends,
changes in the legal and legislative environment and the current economic
environment to develop a point estimate based upon management's judgment and
past experience. The series of selected point estimates is then combined to
produce an overall point estimate for ultimate losses.

HCPL. Over the past several years the most influential factor affecting the
analysis of our HCPL reserves and the related development recognized has been an
observed increase in claim severity for the broader medical professional
liability industry as well as higher initial loss expectations on incurred
claims. The severity trend is an explicit component of our pricing models and
directly impacts the reserving process. Our estimate of this trend and our
expectations about changes in this trend impact a variety of factors, from the
selection of expected loss ratios to the ultimate point estimates established by
management.

Because of the implicit and wide-ranging nature of severity trend assumptions on
the loss reserving process, it is not practical to specifically isolate the
impact of changing severity trends. However, because severity is an explicit
component of our HCPL pricing process we can better isolate the impact that
changing severity can have on our loss costs and loss ratios in regards to our
pricing models for this business component. Our current HCPL pricing models
assume severity trends in the range of 2% to 5% depending on state, territory
and specialty. In some portions of our HCPL business we have observed and
reflected higher severity trends in our estimates of losses and loss adjustment
expenses.

Due to the long-tailed nature of our claims and the previously discussed
historical volatility of loss costs, selection of a severity trend assumption is
a subjective process that is inherently likely to prove inaccurate over time.
Given the long tail and volatility, we are generally cautious in making changes
to the severity assumptions within our pricing models. All open claims and
accident years are generally impacted by a change in the severity trend, which
compounds the effect of such a change.

Although the future degree and impact of the ultimate severity trend remains
uncertain due to the long-tailed nature of our business, we have given
consideration to observed loss costs in setting our rates. For our HCPL
business, this practice had generally resulted in rate reductions as claim
frequency declined and remained at historically low levels. However, from early
2017 to the current period, the average pricing on renewed business has steadily
increased reflective of the rising loss cost environment, and we anticipate
further renewal pricing increases due to increasing loss severity.

More recently, another factor affecting our analysis of our HCPL reserves and
the related development recognized is the reduction in claims frequency in 2020,
some of which is likely associated with the COVID-19 pandemic, as previously
discussed. In 2020, we established a $10 million IBNR reserve related to
COVID-19. Given the consistent and prolonged nature of the favorable claims
frequency trend and the fact that early first notices have not materialized into
claims, we recognized net favorable prior accident year reserve development of
$1 million associated with our COVID-19 IBNR reserve during the third quarter of
2021. Similar to our views on our current accident year reserve, we continue to
remain cautious in recognizing the full impact of these favorable frequency
trends in our prior accident year reserve due to the long-tailed nature of our
HCPL claims as well as the uncertainty surrounding the length and severity of
the pandemic. At December 31, 2021, we maintain a $9 million IBNR reserve
related to COVID-19 which represents our best estimate of future COVID-19
related losses not already captured by our claims process based on currently
available information and reported incidents.

Workers' Compensation. The projection of changes in claim severity trend has not
historically been an influential factor affecting our analysis of workers'
compensation reserves, as claims are typically resolved more quickly than the
industry norm. As previously mentioned, the determination and calculation of
loss development factors, in particular, the selection of tail factors which are
used to extend the projection of losses beyond historical data, requires
considerable judgment.

Loss Development by Line of Business

Professional Liability


Our professional liability line of business includes both our HCPL and Small
Business Unit lines, with our HCPL line representing the largest component of
our reserve. Our HCPL line of business also includes the business acquired
through the NORCAL transaction that closed on May 5, 2021. In support of our
concern that the decline in frequency will result in a higher severity trend for
our HCPL claims, we saw our closed-with-indemnity-payment ratio (i.e., the
number of claims closed with an indemnity or loss payment as compared to the
total number of closed claims) for our claims increase from 15% in 2012 to 18%
in 2021 (ratios exclude NORCAL claims).

The following table presents additional information about the loss development
for our professional liability line of business, excluding loss development for
HCPL coverages assumed by the SPCs at Inova Re and Eastern Re. Furthermore, loss
development for our professional liability line of business for the year ended
December 31, 2021 includes the business acquired through the NORCAL transaction
since the date of acquisition, excluding the amortization of the purchase
accounting fair value adjustment:

Development recognized during 2021 principally related to accident years 2015
through 2020. In addition, we recognized favorable prior year reserve
development of $1 million in 2021 related to the 2020 accident year associated
with our COVID-19 IBNR reserve, as previously discussed, due to the fact that
early first notices have not materialized into claims. We continue to remain
cautious in our evaluation of our prior accident year reserve due to the
long-tailed nature of our HCPL claims as well as the uncertainty surrounding the
length and severity of the pandemic. Not included in the table above, is $7.9
million of amortization of the purchase accounting fair value adjustment on
NORCAL's assumed net reserve and amortization of the negative VOBA associated
with NORCAL's DDR reserve which is recorded as a reduction to prior accident
year net losses and loss adjustment expenses in 2021. We have not recognized any
development related to NORCAL's prior accident year reserves since the date of
acquisition. See Note 2 of the Notes to Consolidated Financial Statements for
additional information on the NORCAL acquisition and the related purchase
accounting adjustments. Development recognized during 2020 principally related
to accident years 2014 through 2017. Not included in the above table, as
previously discussed, is $2.5 million and $4.4 million of favorable development
recognized during 2021 and 2020, respectively, in our Segregated Portfolio Cell
Reinsurance segment related to the HCPL coverages assumed by the SPCs at Inova
Re and Eastern Re. During 2019 the loss experience in our Specialty line of
business deteriorated further, particularly in regard to the reserves we
established for a large national healthcare account. This deterioration is the
primary driver of the unfavorable development we recognized in 2019 for accident
years 2016 through 2018.

Approximately $7.6 million of the $8.1 million total net favorable development
recognized in 2021 related to the 2015 through 2020 accident years. The
development for the 2015 through 2020 accident years represents an 11.3%
reduction to the ultimates established for those reserves at December 31, 2020.
Approximately $5.3 million of the $8.6 million total net favorable development
recognized in 2020 related to the 2017 through 2019 accident years. The
development for the 2017 through 2019 accident years represents a 13.7%
reduction to the ultimates established for those reserves at December 31, 2019.
Approximately $6.8 million of the $12.8 million total net favorable development
recognized in 2019 related to the 2014 through 2017 accident years. The
development for the 2014 through 2017 accident years represents a 13.7%
reduction to the ultimates established for those reserves at December 31, 2018.

In 2021, 2020 and 2019 the development was largely attributable to favorable
results from claims closed during the year. As time has elapsed we have
recognized that actual loss experience has on average been better than
estimated. We have been cautious in recognizing the improvement, but as claims
have matured and claims are closed or have become more certain for the remaining
open claims, we have revised reserve estimates. We believe the need for a
cautious approach is required as outcomes are uncertain and results can be
significantly affected by outcomes for a small number of cases.

Workers' Compensation


Claims in our workers' compensation line of business have historically closed at
a faster rate than in our HCPL or Medical Technology Liability lines of
business. This faster disposition rate, along with a lower net retention after
the application of reinsurance, has resulted in less volatility in loss
estimates on a net basis. However, a change in the number of individually-severe
claims can create volatility in a given accident year. The following table
presents additional information about the loss development for our workers'
compensation line of business:

In 2021, we recognized $7.6 million of net favorable development in our
Segregated Portfolio Cell Reinsurance segment related to workers' compensation
business and $7.1 million of net favorable development in our Workers'
Compensation Insurance segment. In 2020, we recognized $12.1 million of net
favorable development in our Segregated Portfolio Cell Reinsurance segment
related to workers' compensation business and $7.0 million of net favorable
development in our Workers' Compensation Insurance segment. In 2019, we
recognized $10.1 million of net favorable development in our Segregated
Portfolio Cell Reinsurance segment, all related to workers' compensation
business, and $7.8 million of net favorable development in our Workers'
Compensation Insurance segment. Not included in the table above, net favorable
development in our Workers' Compensation Insurance segment in 2019 included $1.6
million related to the amortization of the purchase accounting fair value
adjustment. As previously discussed, this fair value adjustment has been fully
amortized as of December 31, 2019.

Variability of Loss Reserves


As previously noted, the number of data points and variables considered and the
subjective process followed in establishing our loss reserve makes it
impractical to isolate individual variables and demonstrate their impact on our
estimate of loss reserves. However, to provide a better understanding of the
potential variability in our reserves, we have modeled implied reserve ranges
around our single point net reserve estimates for our various lines of business
assuming different confidence levels. The ranges have been developed by
aggregating the expected volatility of losses across partitions of our business
to obtain a consolidated distribution of potential reserve outcomes. The
aggregation of this data takes into consideration correlations among our
geographic and specialty mix of business. The result of the correlation approach
to aggregation is that the ranges are narrower than the sum of the ranges
determined for each partition.

We have used this modeled statistical distribution to calculate an 80% and 60%
confidence interval for the potential outcome of our consolidated net reserve
for losses. The high and low end points of the distributions are as follows:

                              Low End Point        Carried Net Reserve      

High End Point

80% Confidence Level $2.327 billion $3.128 billion

$4.051 billion

60% Confidence Level $2.540 billion $3.128 billion

$3.651 billion

Any change in our estimate of net ultimate losses for prior years is reflected
in net income (loss) in the period in which such changes are made.


Due to the size of our consolidated reserve for losses and the large number of
claims outstanding at any point in time, even a small percentage adjustment to
our total reserve estimate could have a material effect on our results of
operations for the period in which the adjustment is made, as was the case in
2021, 2020 and 2019.

Reinsurance


We use insurance and reinsurance (collectively, "reinsurance") to provide
capacity to write larger limits of liability, to provide reimbursement for
losses incurred under the higher limit coverages we offer, to provide protection
against losses in excess of policy limits and, in the case of risk sharing
arrangements, to align our objectives with those of our strategic business
partners and to provide custom insurance solutions for large customer groups.
The purchase of reinsurance does not relieve us from the ultimate risk on our
policies; however, it does provide reimbursement for certain losses we pay.

We make a determination of the amount of insurance risk we choose to retain
based upon numerous factors, including our risk tolerance and the capital we
have to support it, the price and availability of reinsurance, the volume of
business, our level of experience with a particular set of exposures and our
analysis of the potential underwriting results. We purchase excess of loss
reinsurance to limit the amount of risk we retain and we do so from a number of
companies to mitigate concentrations of credit risk. As of December 31, 2021,
there is no reinsurer, on an individual basis, for which our recoverables for
both paid and unpaid claims (net of amounts due to the reinsurer) and our
prepaid balances are more than $52 million, in aggregate. We utilize reinsurance
brokers to assist us in the placement of these reinsurance programs and in the
analysis of the credit quality of our reinsurers. The determination of which
reinsurers we choose to do business with is based upon an evaluation of their
then current financial strength, rating, stability and claims payment practices.

We evaluate each of our ceded reinsurance contracts at inception to confirm that
there is sufficient risk transfer to allow the contract to be accounted for as
reinsurance under current accounting guidance. At December 31, 2021, all ceded
contracts were accounted for as risk transferring contracts.

Our receivable from reinsurers on unpaid losses and loss adjustment expenses
represents our estimate of the amount of our reserve for losses that will be
recoverable under our reinsurance programs. We base our estimate of funds
recoverable upon our expectation of ultimate losses and the portion of those
losses that we estimate to be allocable to reinsurers based upon the terms and
conditions of our reinsurance agreements. Our assessment of the collectability
of the recorded amounts receivable from reinsurers considers the payment history
of the reinsurer, publicly available financial and rating agency data, our
interpretation of the underlying contracts and policies and responses by
reinsurers.

Given the uncertainty inherent in our estimates of losses and related amounts
recoverable from reinsurers, these estimates may vary significantly from the
ultimate outcome.

Under the terms of certain of our reinsurance agreements, the amount of premium
that we cede to our reinsurers is based in part on the losses we recover under
the agreements. Therefore, we make an estimate of premiums ceded under these
reinsurance agreements subject to certain minimums and maximums. Any adjustments
to our estimates of losses recoverable under our reinsurance agreements or the
premiums owed under our agreements are reflected in current operations. Due to
the size of our reinsurance balances, an adjustment to these estimates could
have a material effect on our results of operations for the period in which the
adjustment is made.

Our reinsurance receivables are exposed to credit losses but to date have not
experienced any significant amount of credit losses. To partially mitigate our
exposure to credit losses, reinsurance receivables totaling approximately $97.9
million were collateralized by letters of credit or funds withheld as of
December 31, 2021. We measure expected credit losses on our reinsurance
receivables on a collective basis when similar risk characteristics exist or on
an individual basis if we determine a receivable does not share similar risk
characteristics. We measure expected credit losses associated with our
reinsurance receivables (related to both paid and unpaid losses) at the
consolidated level as our reinsurance receivables share similar risk
characteristics including type of financial asset, type of industry and similar
historical and expected credit loss patterns. We measure expected credit losses
over the average contractual term of our reinsurance receivables utilizing a
loss rate method. Historical internal credit loss experience is the basis for
our assessment of expected credit losses; however, we may also consider
historical credit loss information from external sources. We also consider
reasonable and supportable forecasts of future economic conditions in our
estimate of expected credit losses. Expected credit losses associated with our
reinsurance receivables (related to both paid and unpaid losses) were nominal in
amount as of December 31, 2021 and 2020. No reinsurance balances were written
off for credit reasons during the years ended December 31, 2021 or 2020. Should
our expected credit loss analysis or other facts or circumstances lead us to
believe that any reinsurer may not meet its obligations to us, adjustments to
the allowance for expected credit losses or to reinsurance receivables would be
reflected in current operations. Such an adjustment has the potential to be
material to the results of operations in the period in which it is recorded;
however, we would not expect such an adjustment to have a material effect on our
capital position or our liquidity. For further information on our allowance for
expected credit losses related to our receivables from reinsurers see Note 1 of
the Notes to Consolidated Financial Statements.

Fair value is defined as the price that would be received to sell an asset or
paid to transfer a liability in an orderly transaction between market
participants at the measurement date. All of our fixed maturity and equity
investments are carried at fair value. The fair value of our short-term
securities approximates the cost of the securities due to their short-term
nature.


Because of the number of securities we own and the complexity of developing
accurate fair values, we utilize multiple independent pricing services to assist
us in establishing the fair value of individual securities. The pricing services
provide fair values based on exchange-traded prices, if available. If an
exchange-traded price is not available, the pricing services, if possible,
provide a fair value that is based on multiple broker/dealer quotes or that has
been developed using pricing models. Pricing models vary by asset class and
utilize currently available market data for securities comparable to ours to
estimate a fair value for our securities. The pricing services scrutinize market
data for consistency with other relevant market information before including the
data in the pricing models. The pricing services disclose the types of pricing
models used and the inputs used for each asset class. Determining fair values
using these pricing models requires the use of judgment to identify appropriate
comparable securities and to choose a valuation methodology that is appropriate
for the asset class and available data.

The pricing services provide a single value per instrument quoted. We review the
values provided for reasonableness each quarter by comparing market yields
generated by the supplied value versus market yields observed in the
marketplace. We also compare yields indicated by the provided values to
appropriate benchmark yields and review for values that are unchanged or that
reflect an unanticipated variation as compared to prior period values. We
utilize a primary pricing service for each security type and compare provided
information for consistency with alternate pricing services, known market data
and information from our own trades, considering both values and valuation
trends. We also review weekly trades versus the prices supplied by the services.
If a supplied value appears unreasonable, we discuss the valuation in question
with the pricing service and make adjustments if deemed necessary. Historically
our review has not resulted in any material changes to the values supplied by
the pricing services. The pricing services do not provide a fair value unless an
exchange-traded price or multiple observable inputs are available. As a result,
the pricing services may provide a fair value for a security in some periods but
not others, depending upon the level of recent market activity for the security
or comparable securities.

Level 1 Investments

Fair values for a majority of our equity securities and portions of our
short-term and convertible securities are determined using exchange-traded
prices. There is little judgment involved when fair value is determined using an
exchange-traded price. In accordance with GAAP, we classify securities valued
using an exchange-traded price as Level 1 securities.

Level 2 Investments


Most fixed income securities do not trade daily; thus, exchange-traded prices
are generally not available for these securities. However, market information
(often referred to as observable inputs or market data, including but not
limited to, last reported trade, non-binding broker quotes, bids, benchmark
yield curves, issuer spreads, two-sided markets, benchmark securities, offers
and recent data regarding assumed prepayment speeds, cash flow and loan
performance data) is available for most of our fixed income securities. We
determine fair value for a large portion of our fixed income securities using
available market information. In accordance with GAAP, we classify securities
valued based on multiple market observable inputs as Level 2 securities.

Level 3 Investments


When a pricing service does not provide a value for one of our fixed maturity
securities, management estimates fair value using either a single non-binding
broker quote or pricing models that utilize market based assumptions which have
limited observable inputs. The process involves significant judgment in
selecting the appropriate data and modeling techniques to use in the valuation
process. In accordance with GAAP, we classify securities valued using limited
observable inputs as Level 3 securities.

Fair Values Not Categorized


We hold interests in certain investment funds, primarily LPs/LLCs, which measure
fund assets at fair value on a recurring basis and provide us with a NAV for our
interest. As a practical expedient, we consider the NAV provided to approximate
the fair value of the interest. In accordance with GAAP, we do not categorize
these investments within the fair value hierarchy.

Nonrecurring Fair Value Measurements


We measure the fair value of certain assets on a nonrecurring basis when events
or changes in circumstances indicate that the carrying amount of the asset may
not be recoverable. These assets include investments carried principally at
cost, investments in tax credit partnerships, fixed assets, goodwill and other
intangible assets. These assets would also include any equity method investments
that do not provide a NAV. During the third quarter of 2020, we recognized a
nonrecurring fair value measurement related to the goodwill in our Specialty P&C
reporting unit with a carrying value of $161.1 million prior to the fair value
measurement. This nonrecurring fair value measurement resulted in the goodwill
being written down to its implied fair value of zero resulting in an impairment
of the goodwill of $161.1 million (see following discussion under the heading
"Goodwill / Intangibles" and Note 8 of the Notes to Consolidated Financial
Statements). The inputs used in the fair value measurement were non-observable
and, as such, were categorized as a Level 3 valuation. We did not have any other
assets or liabilities that were measured at fair value on a nonrecurring basis
at December 31, 2021 or December 31, 2020.

Investments - Other Valuation Methodologies


Certain of our investments, in accordance with GAAP for the type of investment,
are measured using methodologies other than fair value. At December 31, 2021,
these investments represented approximately 3% of total investments, and are
detailed in the following table. Additional information about these investments
is provided in Note 3 and Note 4 of the Notes to Consolidated Financial
Statements.

Impairments


We evaluate our available-for-sale investment securities, which at December 31,
2021 and December 31, 2020 consisted entirely of fixed maturity securities, on
at least a quarterly basis for the purpose of determining whether declines in
fair value below recorded cost basis represent an impairment loss. We consider a
credit-related impairment loss to have occurred:

•if there is intent to sell the security;
•if it is more likely than not that the security will be required to be sold
before full recovery of its amortized cost basis; or
•if the entire amortized basis of the security is not expected to be recovered.

The assessment of whether the amortized cost basis of a security is expected to
be recovered requires management to make assumptions regarding various matters
affecting future cash flows. The choice of assumptions is subjective and
requires the use of judgment. Actual credit losses experienced in future periods
may differ from management's estimates of those credit losses. Methodologies
used to estimate the present value of expected cash flows are:

The estimate of expected cash flows is determined by projecting a recovery value
and a recovery time frame and assessing whether further principal and interest
will be received. We consider various factors in projecting recovery values and
recovery time frames, including the following:

•third-party research and credit rating reports;
•the current credit standing of the issuer, including credit rating downgrades,
whether before or after the balance sheet date;
•the extent to which the decline in fair value is attributable to credit risk
specifically associated with the security or its issuer;

                                       53

--------------------------------------------------------------------------------

  Table of Contents
•internal assessments and the assessments of external portfolio managers
regarding specific circumstances surrounding an investment, which indicate the
investment is more or less likely to recover its amortized cost than other
investments with a similar structure;
•for asset-backed securities, the origination date of the underlying loans, the
remaining average life, the probability that credit performance of the
underlying loans will deteriorate in the future and our assessment of the
quality of the collateral underlying the loan;
•failure of the issuer of the security to make scheduled interest or principal
payments;
•any changes to the rating of the security by a rating agency;
•recoveries or additional declines in fair value subsequent to the balance sheet
date;
•adverse legal or regulatory events;
•significant deterioration in the market environment that may affect the value
of collateral (e.g., decline in real estate prices);
•significant deterioration in economic conditions; and
•disruption in the business model resulting from changes in technology or new
entrants to the industry.

If deemed appropriate and necessary, a discounted cash flow analysis is
performed to confirm whether a credit loss exists and, if so, the amount of the
credit loss. We use the single best estimate approach for available-for-sale
debt securities and consider all reasonably available data points, including
industry analyses, credit ratings, expected defaults and the remaining payment
terms of the debt security. For fixed rate available-for-sale debt securities,
cash flows are discounted at the security's effective interest rate implicit in
the security at the date of acquisition. If the available-for-sale debt
security's contractual interest rate varies based on subsequent changes in an
independent factor, such as an index or rate, for example, the prime rate, the
LIBOR, or the U.S. Treasury bill weekly average, that security's effective
interest rate is calculated based on the factor as it changes over the life of
the security. If we intend to sell a debt security or believe we will more
likely than not be required to sell a debt security before the amortized cost
basis is recovered, any existing allowance will be written off against the
security's amortized cost basis, with any remaining difference between the debt
security's amortized cost basis and fair value recognized as an impairment loss
in earnings.

Exclusive of securities where there is an intent to sell or where it is not more
likely than not that the security will be required to be sold before recovery of
its amortized cost basis, impairment for debt securities is separated into a
credit component and a non-credit component. The credit component of an
impairment is the difference between the security's amortized cost basis and the
present value of its expected future cash flows, while the non-credit component
is the remaining difference between the security's fair value and the present
value of expected future cash flows. An allowance for expected credit losses
will be recorded for the expected credit losses through income and the
non-credit component is recognized in OCI. The amount of impairment recognized
is limited to the excess of the amortized cost over the fair value of the
available-for-sale debt security.

Pension


As a result of our NORCAL acquisition, we sponsor a frozen qualified defined
benefit pension plan which covers substantially all NORCAL employees (except
those that were previous employees of Medicus Insurance Company and FD Insurance
Company, employees of PPM RRG as well as new hires after December 31, 2013).
Accounting for pension benefits requires the use of assumptions for the
valuation of the PBO and the expected performance of the plan assets.

We use December 31 as the measurement date for calculating our obligation
related to this defined benefit pension plan and for estimating net periodic
benefit cost (credit) for the subsequent year. The PBO for pension benefits
represents the present value of all future benefits earned as of the measurement
date for vested and non-vested employees. At each measurement date, we review
the various assumptions impacting the amounts recorded for the pension plan
including the discount rates, which impacts the recorded value of the PBO and
interest costs, and the expected return on plan assets.

To estimate the discount rate at the measurement date, we use a bond yield curve
model, developed based on pricing and yield information for high quality
corporate bonds. The assumption for the expected return on plan assets is based
on the anticipated returns that will be earned by the portfolio over the
long-term. The expected return on plan assets is influenced, but not determined,
by historical portfolio performance. We assumed a 3.75% expected return on plan
assets on our pension plan assets for the year ended December 31, 2021. For
2022, we increased our expected return on plan assets assumption to 4.0% based
on our long-term outlook for the capital markets.

Accounting standards provide for the delayed recognition of differences between
actual results and expected or estimated results. This delayed recognition of
the differences is amortized into earnings over time. The differences between
actual results and expected or estimated results are recognized in full in AOCI.
Amounts recognized in AOCI are reclassified to earnings in a systematic manner
over the average future service period of participants. During 2022, we expect
to recognize net pension income of approximately $1.1 million and we do not
expect that contributions to the pension plan will be required during 2022 nor
do we anticipate making any discretionary contributions.

Deferred Policy Acquisition Costs


Policy acquisition costs (primarily commissions, premium taxes and underwriting
salaries) which are directly related to the successful acquisition of new and
renewal premiums are capitalized as DPAC and charged to expense, net of ceding
commissions earned, as the related premium revenue is recognized. We evaluate
the recoverability of our DPAC typically at the segment level each reporting
period or in a manner that is consistent with the way we manage our business.
Any amounts estimated to be unrecoverable are charged to expense in the current
period.

As part of our evaluation of the recoverability of DPAC, we also evaluate our
unearned premiums for premium deficiencies. A premium deficiency is recognized
if the sum of anticipated losses and loss adjustment expenses, unamortized DPAC
and maintenance costs, net of anticipated investment income, exceeds the related
unearned premium. If a premium deficiency is identified, the associated DPAC is
written off, and a PDR is recorded for the excess deficiency as a component of
net losses and loss adjustment expenses in our Consolidated Statements of Income
and Comprehensive Income and as a component of the reserve for losses and loss
adjustment expenses on our Consolidated Balance Sheets. For the years ended
December 31, 2021 and 2020, we did not determine any DPAC to be unrecoverable.
For the year ended December 31, 2019, a nominal amount of DPAC was charged to
expense as it was determined to be unrecoverable and a $9.2 million PDR was
established in our Specialty P&C segment related to a large national healthcare
account. The $9.2 million PDR was fully amortized during 2020.

Deferred Taxes


Deferred federal income taxes arise from the recognition of temporary
differences between the basis of assets and liabilities determined for financial
reporting purposes and the basis determined for income tax purposes. Our
temporary differences principally relate to our loss reserves, unearned and
advanced premiums, DPAC, NOL and tax credit carryforwards, compensation related
items, unrealized investment gains (losses) and basis differences on fixed
assets, intangible assets and operating leases. Deferred tax assets and
liabilities are measured using the enacted tax rates expected to be in effect
when such benefits are realized. We review our deferred tax assets quarterly for
impairment. If we determine that it is more likely than not that some or all of
a deferred tax asset will not be realized, a valuation allowance is recorded to
reduce the carrying value of the asset. In assessing the need for a valuation
allowance, management is required to make certain judgments and assumptions
about our future operations based on historical experience and information as of
the measurement period regarding reversal of existing temporary differences,
carryback capacity, future taxable income of the appropriate character
(including its capital and operating characteristics) and tax planning
strategies.

A valuation allowance was established in a prior year against the deferred tax
asset related to the NOL carryforwards for the U.K. operations and in 2020
against a portion of the deferred tax asset related to the U.S. state NOL
carryforwards. In addition, a valuation allowance was established in 2021
against the net deferred tax asset of ProAssurance American Mutual, a Risk
Retention Group. As a taxpayer separate from the consolidated group, this entity
has experienced cumulative losses in recent years. Management concluded that it
was more likely than not that these deferred tax assets will not be realized. We
also established a valuation allowance in a prior year against the deferred tax
assets of certain SPCs at our wholly owned Cayman Islands reinsurance
subsidiary, Inova Re. Due to the cumulative losses incurred in recent years by
these SPCs, management

                                       55

--------------------------------------------------------------------------------

concluded that a valuation allowance was required. We evaluated the
realizability of the deferred tax assets acquired from NORCAL during our
accounting for the acquisition and management concluded that it was more likely
than not that the acquired deferred tax assets would be realized. As of
December 31, 2021, management concluded that the previously recorded valuation
allowances were still required against the deferred tax assets related to the
NOL carryforwards for the U.K. operations, against the deferred tax assets
related to the U.S. state NOL carryforwards and against the deferred tax assets
of certain SPCs at Inova Re. Management's assessment of the need for these
valuation allowances at December 31, 2021 included an analysis of the available
sources of income, including projections of income for the consolidated group
following the NORCAL acquisition. See further discussion on ProAssurance's
deferred tax assets in Note 7 of the Notes to Consolidated Financial Statements.

U.S. Tax Legislation

Coronavirus Aid, Relief and Economic Security Act


In response to COVID-19, the CARES Act was signed into law on March 27, 2020 and
contains several provisions for corporations and eased certain deduction
limitations originally imposed by the TCJA. See further discussion in Note 7 of
the Notes to Consolidated Financial Statements. Temporary changes regarding NOL
carryback provisions included in the CARES Act had a favorable impact on our
liquidity, as we were able to carryback our 2019 and 2020 net operating losses
to claim refunds (see discussion that follows in the Liquidity and Capital
Resources and Financial Condition section under the heading "Taxes"). See
further discussion in Note 7 of the Notes to Consolidated Financial Statements.

American Rescue Plan Act of 2021


In response to economic concerns associated with COVID-19, the American Rescue
Plan Act of 2021 was signed into law on March 11, 2021 and includes an expansion
of the number of employees covered by the limitation on the deductibility of
compensation in excess of $1 million. This provision is effective for tax years
beginning after December 31, 2026. We have evaluated this provision as well as
the other provisions of the American Rescue Plan Act of 2021 and concluded that
they will not have a material impact on our financial position or results of
operations as of December 31, 2021. See further discussion in Note 7 of the
Notes to Consolidated Financial Statements.

Unrecognized Tax Benefits


We evaluate tax positions taken on tax returns and recognize positions in our
financial statements when it is more likely than not that we will sustain the
position upon resolution with a taxing authority. If recognized, the benefit is
measured as the largest amount of benefit that has a greater than 50%
probability of being realized. We review uncertain tax positions each quarter,
considering changes in facts and circumstances, such as changes in tax law,
interactions with taxing authorities and developments in case law, and make
adjustments as we consider necessary. Adjustments to our unrecognized tax
benefits may affect our income tax expense, and settlement of uncertain tax
positions may require the use of cash. Other than differences related to timing,
no significant adjustments were considered necessary during 2021 or 2020. At
December 31, 2021, our liability for unrecognized tax benefits approximated $3.0
million.

Goodwill / Intangibles

Goodwill and intangible assets are tested for impairment annually or more
frequently if circumstances indicate an impairment may have occurred. The date
of our annual impairment testing is October 1. Impairment of goodwill is tested
at the reporting unit level, which is consistent with our reportable segments
identified in Note 19 of the Notes to Consolidated Financial Statements.

Interim Impairment Assessments


During the third quarter of 2020, we performed interim impairment assessments of
the goodwill and definite and indefinite lived intangible assets in our
Specialty P&C, Workers' Compensation Insurance and Segregated Portfolio Cell
Reinsurance reporting units due to the significant market volatility impacting
our actual and projected results along with a decline in our stock price. The
goodwill analysis indicated an impairment of the goodwill associated with our
Specialty P&C reporting unit and accordingly we recorded a $161.1 million charge
to goodwill (see further discussion in Note 8 of the Notes to Consolidated
Financial Statements). The analysis of our definite and indefinite lived
intangible assets indicated no impairment at September 30, 2020.

Annual Impairment Assessment


When testing goodwill for impairment on our annual test date, we have the option
to first assess qualitative factors to determine whether the existence of events
or circumstances leads to a determination that it is more likely than not that
the estimated fair value of a reporting unit is less than its carrying amount.
If we elect to perform a qualitative assessment and

                                       56

--------------------------------------------------------------------------------

Table of Contents

determine that an impairment is more likely than not, we are then required to
perform a quantitative impairment test; otherwise, no further analysis is
required. We also may elect not to perform the qualitative assessment and,
instead, proceed directly to the quantitative impairment test.


Performance of the qualitative goodwill impairment assessment requires judgment
in identifying and considering the significance of relevant key factors, events,
and circumstances that affect the fair values of our reporting units. This
requires consideration and assessment of external factors such as macroeconomic,
industry, and market conditions, as well as entity-specific factors, such as our
actual and planned financial performance. We also give consideration to the
difference between each reporting unit's fair value and carrying value as of the
most recent date that a fair value measurement was performed. If the results of
the qualitative assessment conclude that it is not more likely than not that the
fair value of a reporting unit exceeds its carrying value, additional
quantitative impairment testing is performed.

The quantitative goodwill impairment test involves comparing the fair value of a
reporting unit with its carrying value including goodwill. If the fair value of
a reporting unit exceeds its carrying value, the reporting unit's goodwill is
considered not to be impaired. However, if the carrying value of a reporting
unit exceeds its fair value, an impairment loss is recorded in an amount equal
to that excess. Any impairment charge recognized is limited to the amount of the
respective reporting unit's allocated goodwill.

Determining the fair value of a reporting unit under the quantitative goodwill
impairment test requires judgment and often involves the use of significant
estimates and assumptions, including an assessment of external factors such as
macroeconomic, industry, and market conditions, as well as entity-specific
factors, such as actual and planned financial performance. These estimates and
assumptions could have a significant impact on whether or not an impairment
charge is recognized and the magnitude of any such charge. To assist management
in the process of determining any potential goodwill impairment, we may review
and consider appraisals from accredited independent valuation firms. Estimates
of fair value are primarily determined using discounted cash flows and market
comparisons. These approaches involve significant estimates and assumptions,
including projected future cash flows (including timing), discount rates
reflecting the risks inherent in those future cash flows, perpetual growth
rates, and selection of appropriate market comparable metrics and transactions.

During 2021, we experienced an increase in accident year reported losses,
including increased severity-related claim activity in our Workers' Compensation
Insurance segment. We primarily attribute this increase in reported losses and
severity-related claim activity to workers being out of "work shape" as they
returned to employment in 2021, as well as the lack of training, alternative
work arrangements and employee fatigue due to the labor shortage. As a result,
we increased our 2021 current accident year loss ratio in our Workers'
Compensation Insurance reporting unit during the third quarter of 2021. Due to
the increase in the current accident year loss ratio, management decided to
bypass the optional qualitative impairment test and proceed directly to the
quantitative impairment test for both the Workers' Compensation Insurance and
Segregated Portfolio Cell Reinsurance reporting units for the most recent
goodwill impairment test performed on October 1, 2021. In applying the
quantitative approach, management estimated the fair value of the Workers'
Compensation Insurance and Segregated Portfolio Cell Reinsurance reporting units
using both an income approach and market approach using the aforementioned
valuation methodologies and process for developing assumptions. To corroborate
the reporting units' valuation, we performed a reconciliation of the estimate of
the aggregate fair value of the reporting units to ProAssurance's market
capitalization, including consideration of a control premium. As a result of the
quantitative assessments, management concluded that the fair value of each of
the Workers Compensation Insurance and Segregated Portfolio Cell Reinsurance
reporting units exceeded the carrying value as of the testing date; therefore,
goodwill was not impaired and no further goodwill impairment testing was
required. No goodwill impairment was recorded during the year ended December 31,
2021. See Note 8 of the Notes to Consolidated Financial Statements for
additional information about our goodwill. The analysis of our definite and
indefinite lived intangible assets indicated no impairment at December 31, 2021.

Acquired Intangibles


The acquisition of NORCAL added $14 million to identifiable intangible assets as
of the acquisition date. Intangible assets acquired in the NORCAL acquisition
included the following:

Business Combinations


We accounted for our acquisition of NORCAL in accordance with GAAP relating to
business combinations which required us to make certain estimates and
assumptions including determining the fair value of the non-cash components of
the acquisition consideration and the acquisition date fair values of the
acquired tangible and identifiable intangible assets and assumed liabilities of
NORCAL. Subsequent to the preliminary valuation of the non-cash components of
the purchase consideration and net assets acquired, any adjustment identified
associated with the purchase price allocation will be evaluated to determine
whether the adjustment represents a measurement period adjustment in accordance
with GAAP. If the adjustment is deemed to be a measurement period adjustment and
is identified within one year of the acquisition, then the measurement period
adjustment will be recorded in the current reporting period with a corresponding
adjustment to the gain on bargain purchase.

Contingent Consideration


Contingent consideration in a business combination is recorded at fair value on
the date of the acquisition and remeasured each subsequent reporting period with
changes in fair value recognized in earnings. The purchase consideration in the
NORCAL acquisition included contingent consideration with an acquisition date
fair value of approximately $24 million. NORCAL policyholders who tendered
NORCAL stock to ProAssurance are eligible for a share of contingent
consideration in an amount of up to approximately $84 million depending upon the
after-tax development of NORCAL's ultimate net losses between December 31, 2020
and December 31, 2023. The estimated fair value of this contingent consideration
was $24 million as of December 31, 2021, which did not change from the
acquisition date of May 5, 2021, and was derived utilizing a stochastic model.
This estimate does not guarantee that contingent consideration will ultimately
be paid. Depending on NORCAL's actual ultimate net loss development between
December 31, 2020 and December 31, 2023, the actual amount due to eligible
policyholders may be greater than or less than the $24 million current fair
value estimate. See further discussion around the contingent consideration in
Note 2 and Note 11 of the Notes to Consolidated Financial Statements.

VOBA


VOBA is an intangible asset (or liability) that reflects the estimated fair
value of in-force contracts acquired in an acquisition and represents the
portion of the purchase price that is allocated to the value of the right to
receive future cash flows from the business in-force at the acquisition date.
VOBA is based on actuarially determined projections, and in instances where the
in-force business is expected to generate an underwriting loss, the value of
VOBA may be negative. Negative VOBA is reported in the reserve for losses and
loss adjustment expenses on the Consolidated Balance Sheets.

We recognized negative VOBA of $11.7 million in connection with our acquisition
of NORCAL, representing the value of future losses expected to be recognized
over the lifetime of the contracts acquired determined using a discount rate and
other relevant assumptions. The negative VOBA will be amortized over a period in
proportion to the earn-out of the premium as a reduction to current accident
year net losses and loss adjustment expenses on the Consolidated Statements of
Income and Comprehensive Income. See Note 2 of the Notes to Consolidated
Financial Statements for more information.

Gain on Bargain Purchase


As a result of the NORCAL acquisition, we recognized a preliminary gain on
bargain purchase of $74.4 million during the second quarter of 2021 representing
the excess of the fair value of the identifiable assets acquired and liabilities
assumed over the purchase consideration. A gain on bargain purchase is
recognized in earnings and is considered unusual, infrequent and non-recurring
in nature. We exclude gains on bargain purchases from Non-GAAP operating income
(loss) as they do not reflect normal operating results. See further discussion
around the gain on bargain purchase recognized in the second quarter of 2021
from the NORCAL acquisition in Note 2 of the Notes to Consolidated Financial
Statements.

Accounting Changes

We did not have any change in accounting estimate or policy that had a material
effect on our results of operations or financial position during 2021. We are
not aware of any accounting changes not yet adopted as of December 31, 2021 that
could have a material effect on our results of operations, financial position or
cash flows.

Liquidity and Capital Resources and Financial Condition

Overview


ProAssurance Corporation is a holding company and is a legal entity separate and
distinct from its subsidiaries. As a holding company, our principal source of
external revenue is our investment revenues. In addition, dividends from our
operating subsidiaries represent another source of funds for our obligations,
including debt service and shareholder dividends. We also charge our operating
subsidiaries within our Specialty P&C (excluding the acquired operating
subsidiaries of NORCAL) and Workers' Compensation Insurance segments a
management fee based on the extent to which services are provided to the
subsidiary and the amount of gross premium written by the subsidiary. At
December 31, 2021, we held cash and liquid investments of approximately
$73 million outside our insurance subsidiaries that were available for use
without regulatory approval or other restriction. We also have $250 million in
permitted borrowings available under our Revolving Credit Agreement as well as
the possibility of a $50 million accordion feature, if successfully subscribed.
As of February 17, 2022, no borrowings were outstanding under our Revolving
Credit Agreement.

During 2021, our operating subsidiaries paid dividends to us of approximately
$51 million. In the aggregate, our insurance subsidiaries are permitted to pay
dividends of approximately $147 million over the course of 2022 without prior
approval of state insurance regulators. However, the payment of any dividend
requires prior notice to the insurance regulator in the state of domicile, and
the regulator may reduce or prevent the dividend if, in its judgment, payment of
the dividend would have an adverse effect on the surplus of the insurance
subsidiary. We make the decision to pay dividends from an insurance subsidiary
based on the capital needs of that subsidiary and may pay less than the
permitted dividend or may also request permission to pay an additional amount
(an extraordinary dividend).

Cash Flows

Cash flows between periods compare as follows:

The principal components of our operating cash flows are the excess of premiums
collected and net investment income over losses paid and operating costs,
including income taxes. Timing delays exist between the collection of premiums
and the payment of losses associated with the premiums. Premiums are generally
collected within the twelve-month period after the policy is written, while our
claim payments are generally paid over a more extended period of time. Likewise,
timing delays exist between the payment of claims and the collection of any
associated reinsurance recoveries.

The decrease in operating cash flows of $18.4 million in 2021 as compared to
2020 was partially offset by additional net cash receipt from NORCAL of
approximately $27.7 million primarily associated with net premium receipts,
partially offset by transaction-related expenses. Excluding NORCAL, operating
cash flows decreased by $46.1 million in 2021 as compared to 2020 primarily due
to a decrease in net premium receipts of $61.9 million driven by our Lloyd's
Syndicates and Specialty P&C segments. The decrease in premium receipts in our
Lloyd's Syndicates segment reflected our decreased participation in the results
of Syndicate 1729 and Syndicate 6131 for the 2021 underwriting year. The
decrease in premium receipts in our Specialty P&C segment was due to our
re-underwriting efforts, the dissolution of our arrangement with CAPAssurance
and the effect of $14.3 million of tail premium received from a large national
healthcare account during the second quarter of 2020 (see further discussion in
our Segment Operating Results - Specialty Property & Casualty section that
follows). Additionally, the decrease in operating cash flows was due to a
decrease in cash received from investment income of $14.6 million driven by a

                                       59

decrease in distributed earnings and redemptions from our portfolio of
investments in LPs/LLCs. Furthermore, the decrease in operating cash flows
reflected the prior year effect of an increase in net cash received of $6.8
million associated with the cash settlement of a quota share reinsurance
agreement between our Specialty P&C segment and one of its reinsurers in 2020.
The decrease in operating cash flows was partially offset by a decrease in paid
losses of $21.8 million driven by our Specialty P&C and Segregated Portfolio
Cell Reinsurance segments. The decrease in paid losses in our Specialty P&C
segment was primarily due to a smaller number of claims resolved with large
indemnity payments as compared to the prior year period, some of which is likely
associated with the COVID-19 pandemic including the disruption of the court
systems. The decrease in paid losses in our Segregated Portfolio Cell
Reinsurance segment reflected the effect of the payment of a $10 million claim
during the first quarter of 2020 by an SPC at Eastern Re in which we do not
participate. This claim payment related to a reserve established by the SPC in
2019 related to an errors and omissions liability policy. Additionally, the
decrease in operating cash flows was partially offset by a decrease in cash paid
for operating expenses of $7.6 million driven by the effect of one-time expenses
of $5.4 million primarily related to employee severance and early retirement
benefits paid to certain employees during the third quarter of 2020 and, to a
lesser extent, a decrease in premium taxes due to a lower volume of premium
written. In addition, the decrease in cash paid for operating expenses was due
to our decreased participation in the results of Syndicate 1729 and Syndicate
6131 for the 2021 underwriting year. The remaining variance in operating cash
flows in 2021 as compared to 2020 was comprised of individually insignificant
components.

The decrease in operating cash flows in 2020 as compared to 2019 of $55.8
million was primarily due to an increase in paid losses of $89.1 million driven
by our Specialty P&C and Segregated Portfolio Cell Reinsurance segments. The
increase in paid losses in our Specialty P&C segment was primarily due to higher
average claim payments. The increase in paid losses in our Segregated Portfolio
Cell Reinsurance segment reflected the aforementioned payment of a $10 million
claim during the first quarter of 2020. Furthermore, the decrease in operating
cash flows reflected a decrease in net cash received of $7.4 million associated
with the cash settlement of the 2017 calendar year quota share reinsurance
agreement between our Specialty P&C segment and Syndicate 1729 due to the
reduction in premiums ceded to Syndicate 1729. The decrease in operating cash
flows also reflected the aforementioned one-time expenses of $5.4 million.
Additionally, the decrease in operating cash flows reflected a decrease in cash
received from investment income of $3.5 million primarily due to a reduction in
dividends received on our equity portfolio resulting from a decrease in our
allocation to this asset category. The decrease in operating cash flows was
somewhat offset by an increase in net premium receipts of $28.1 million and a
decrease in 2020 net tax payments as compared to 2019 of $9.8 million. The
increase in net premium receipts was driven by our Specialty P&C segment due to
$14.3 million of tail premium, as previously discussed. The decrease in net tax
payments was primarily due to refunds received in 2020. Furthermore, the
decrease in operating cash flows was partially offset by an increase in net cash
received of $6.8 million associated with the cash settlement of a quota share
reinsurance agreement, as previously discussed. The remaining variance in
operating cash flows in 2020 as compared to 2019 was comprised of individually
insignificant components.

We manage our investing cash flows to ensure that we will have sufficient
liquidity to meet our obligations, taking into consideration the timing of cash
flows from our investments, including interest payments, dividends and principal
payments, as well as the expected cash flows to be generated by our operations
as discussed in this section under the heading "Investing Activities and Related
Cash Flows."

Our financing cash flows are primarily comprised of dividend payments and
borrowings and repayments under our Revolving Credit Agreement. See further
discussion of our financing activities in this section under the heading
"Financing Activities and Related Cash Flows."

Operating Activities and Related Cash Flows

Losses


The following table, known as the Analysis of Reserve Development, presents
information over the preceding ten years regarding the payment of our losses as
well as changes to (the development of) our estimates of losses during that time
period. As noted in the table, we have completed various acquisitions over the
ten year period which have affected original and re-estimated gross and net
reserve balances as well as loss payments.

The table includes losses on both a direct and an assumed basis and is net of
anticipated reinsurance recoverables. The gross liability for losses before
reinsurance, as shown on the balance sheet, and the reconciliation of that gross
liability to amounts net of reinsurance are reflected below the table. We do not
discount our reserve for losses to present value. Information presented in the
table is cumulative and, accordingly, each amount includes the effects of all
changes in amounts for prior years. The table presents the development of our
balance sheet reserve for losses; it does not present accident year or policy
year development data. Conditions and trends that have affected the development
of liabilities in the past may not necessarily occur in the future. Accordingly,
it is not appropriate to extrapolate future redundancies or deficiencies based
on this table.

The following may be helpful in understanding the Analysis of Reserve
Development
:


•The line entitled "Reserve for losses, undiscounted and net of reinsurance
recoverables" reflects our reserve for losses and loss adjustment expense, less
the receivables from reinsurers, each as reported in our Consolidated Balance
Sheets at the end of each year (the Balance Sheet Reserves).
•The section entitled "Cumulative net paid, as of" reflects the cumulative
amounts paid as of the end of each succeeding year with respect to the
previously recorded Balance Sheet Reserves.
•The section entitled "Re-estimated net liability as of" reflects the
re-estimated amount of the liability previously recorded as Balance Sheet
Reserves that includes the cumulative amounts paid and an estimate of the
remaining net liability based upon claims experience as of the end of each
succeeding year (the Net Re-estimated Liability).
•The line entitled "Net cumulative redundancy (deficiency)" reflects the
difference between the previously recorded Balance Sheet Reserve for each
applicable year and the Net Re-estimated Liability relating thereto as of the
end of the most recent fiscal year.

Table Notes

•We have elected to present reserve history for acquired entities on a
prospective basis in the table above; therefore, certain items will not agree to
the following table which details activity in our net reserve for losses.


•Reserves for 2012 and thereafter include gross and net reserves acquired in
2012 business combinations of $21.8 million and $19.2 million, respectively,
which considers reductions of $3.6 million and $3.3 million, respectively,
recorded in 2013 due to the re-estimation of the fair value of the acquired
reserves.

•Reserves for 2013 include gross and net reserves acquired in 2013 business
combinations of $201.1 million and $126.0 million, respectively.

•Reserves for 2014 include gross and net reserves acquired in 2014 business
combinations of $153.2 million and $139.5 million, respectively.

•Reserves for 2021 include gross and net reserves acquired in 2021 business
combinations of $1.2 billion and $1.1 billion, respectively.


In each year reflected in the table, we have estimated our reserve for losses
utilizing the management and actuarial processes discussed under the heading
"Reserve for Losses and Loss Adjustment Expenses" in the Critical Accounting
Estimates section. Factors that have contributed to the variation in loss
development are primarily related to the extended period of time required to
resolve professional liability claims and include the following:

•The HCPL legal environment deteriorated in the late 1990's and severity began
to increase at a greater pace than anticipated in our rates and reserve
estimates. We addressed the adverse severity trends through increased rates,
stricter underwriting and modifications to claims handling procedures, and
reflected this adverse severity trend when we established our initial reserves
for subsequent years.

•These adverse severity trends later moderated, with that moderation becoming
more pronounced beginning in 2009. We were cautious in giving full recognition
to indications that the pace of severity increase had slowed, however we gave
measured recognition of the improved trend in our reserve estimates. The
favorable development was most pronounced for years 2004 to 2008, as the initial
reserves for these accident years were established prior to substantial
indication that severity trends were moderating. We gave stronger recognition to
the lower severity trend as time elapsed and a greater percentage of claims were
closed.

•A general decline in claims frequency has also been a contributor to favorable
loss development. A significant portion of our policies through 2003 were issued
on an occurrence basis, and a smaller portion of our ongoing business results
from the issuance of extended reporting endorsements which have occurrence-like
exposure. As claims frequency declined, the number of reported claims related to
these coverages was less than originally expected.

•Beginning in 2017, we identified potential higher severity trends in the
broader HCPL industry. These trends were also reflected in increases in
estimates of ultimate losses for open HCPL claims for earlier accident years,
which resulted in a lower amount of favorable development recognized in 2018 and
2017 as compared to prior years.

•During 2019 the loss experience in our Specialty line of business deteriorated
further, particularly in regard to the reserves we established for a large
national healthcare account that experienced losses far exceeding the
assumptions we made when underwriting the account, beginning in 2016. As a
result, we strengthened our Specialty reserves through the recognition of net
unfavorable development on prior accident years and a higher current accident
year net loss ratio in our Specialty P&C segment in 2019.

(1) Current year net losses for the year ended December 31, 2019 included
incurred losses of $2.1 million related to a loss portfolio transfer entered
into during 2019 in the Specialty P&C segment. In addition, current year net
losses for the year ended December 31, 2019 included a PDR of $9.2 million
associated with the unearned premium of a large national healthcare account's
claims-made policy in the Specialty P&C segment. Current year net losses for the
year ended December 31, 2020 included the amortization of the aforementioned
$9.2 million PDR which offsets the impact of the losses incurred associated with
the premium earned related to the large national healthcare account's
claims-made policy.

(2) During 2020, the aforementioned large national healthcare account did not
renew on terms offered by the Company and exercised its contractual option to
purchase extended reporting endorsement or "tail" coverage. As a result, we
recognized total current year losses of $60.0 million (assumes a full limit
loss) within the Specialty P&C segment for the year ended December 31, 2021.

(3) Current year net losses and prior accident year development for the year
ended December 31, 2021 includes certain purchase accounting adjustments
associated with our acquisition of NORCAL. See Note 10 of the Notes to
Consolidated Financial Statements for additional information.


At December 31, 2021 our gross reserve for losses included case reserves of
approximately $2.1 billion and IBNR reserves of approximately $1.4 billion. Our
consolidated gross reserve for losses on a GAAP basis exceeds the combined gross
reserves of our insurance subsidiaries on a statutory basis by approximately
$0.3 billion, which is principally due to the portion of the GAAP reserve for
losses that is reflected for statutory accounting purposes as unearned premiums.
These unearned premiums are applicable to extended reporting endorsements
("tail" coverage) issued without a premium charge upon death, disability or
retirement of an insured who meets certain qualifications.

Reinsurance


Within our Specialty P&C segment, we use insurance and reinsurance
(collectively, "reinsurance") to provide capacity to write larger limits of
liability, to provide reimbursement for losses incurred under the higher limit
coverages we offer and to provide protection against losses in excess of policy
limits. Within our Workers' Compensation Insurance segment, we use reinsurance
to reduce our net liability on individual risks, to mitigate the effect of
significant loss occurrences (including catastrophic events), to stabilize
underwriting results and to increase underwriting capacity by decreasing
leverage. In both our Specialty P&C and Workers' Compensation Insurance
segments, we use reinsurance in risk sharing arrangements to align our
objectives with those of our strategic business partners and to provide custom
insurance solutions for large customer groups. Within our Lloyd's Syndicates
segment, Syndicate 1729 utilizes reinsurance to provide capacity to write larger
limits of liability on individual risks, to provide protection against
catastrophic loss and to provide protection against losses in excess of policy
limits. The purchase of reinsurance does not relieve us from the ultimate risk
on our policies; however, it does provide reimbursement for certain losses we
pay. We pay our reinsurers a premium in exchange for reinsurance of the risk. In
certain of our excess of loss arrangements, the premium due to the reinsurer is
determined by the loss experience of the business

                                       64

reinsured, subject to certain minimum and maximum amounts. Until all loss
amounts are known, we estimate the premium due to the reinsurer. Changes to the
estimate of premium owed under reinsurance agreements related to prior periods
are recorded in the period in which the change in estimate occurs and can have a
significant effect on net premiums earned.

We offer alternative market solutions whereby we cede certain premiums from our
Workers' Compensation Insurance and Specialty P&C segments to either the SPCs at
Inova Re or Eastern Re, our Cayman Islands reinsurance subsidiaries which are
reported in our Segregated Portfolio Cell Reinsurance segment or, to a limited
extent, an unaffiliated captive insurer for one program. The majority of these
policies are reinsured to the SPCs at Inova Re or Eastern Re, net of a ceding
commission. Each SPC at Inova Re and Eastern Re is owned, fully or in part, by
an individual company, agency, group or association and the results of the SPCs
are due to the participants of that cell. We participate to a varying degree in
the results of selected SPCs and, for the SPCs in which we participate, our
participation interest ranges from a low of 20% to a high of 85%. SPC results
attributable to external cell participants are reported as an SPC dividend
expense (income) in our Segregated Portfolio Cell Reinsurance segment. See
further discussion on our SPC operations in the Segment Results - Segregated
Portfolio Cell Reinsurance section that follows. The alternative market workers'
compensation policies are ceded from our Workers' Compensation Insurance segment
to the SPCs under 100% quota share reinsurance agreements. The alternative
market healthcare professional liability policies are ceded from our Specialty
P&C segment to the SPCs under either excess of loss or quota share reinsurance
agreements, depending on the structure of the individual program. The portion of
the risk that is not ceded to an SPC is retained in our Specialty P&C segment
and may also be reinsured under our standard healthcare professional liability
reinsurance program, depending on the policy limits provided. The remaining
premium written in our alternative market business is 100% ceded to an
unaffiliated captive insurer.

Excess of Loss Reinsurance Agreements


We generally reinsure risks under treaties (our excess of loss reinsurance
agreements) pursuant to which the reinsurers agree to assume all or a portion of
all risks that we insure above our individual risk retention levels, up to the
maximum individual limits offered. Generally, these agreements are negotiated
and renewed annually. Our HCPL and Medical Technology Liability treaties renew
annually on October 1. As of October 1, 2021, our HCPL treaty renewed with a
lower gross rate and also incorporated NORCAL policies. For the NORCAL excess of
loss reinsurance arrangement in effect prior to October 1, 2021, NORCAL policies
were reinsured under separate reinsurance agreements, primarily excess of loss,
which have historically renewed annually on January 1. For the NORCAL excess of
loss reinsurance arrangement that renewed on January 1, 2021, retention was
generally the first $2 million in risk and coverages in excess of this amount
are ceded up to $24 million. There were no significant changes in the cost or
structure of our Medical Technology Liability treaty upon the latest renewal on
October 1, 2021. Our Workers' Compensation treaty renews annually on May 1. Our
traditional workers' compensation treaty renewed May 1, 2021 at a higher rate
than the previous agreement, with an increase in the AAD to 3.50% from 3.16% of
ceded earned premium, in excess of the $0.5 million retention per loss
occurrence; all other material treaty terms were consistent with the expiring
agreement. The significant coverages provided by our current excess of loss
reinsurance agreements are detailed in the following table.

(1) Effective October 1, 2020, one prepaid limit reinstatement of $21M and a
second limit reinstatement of up to $21M for the second layer, subject to
reinstatement premium, which attaches after the first reinstatement has been
completely exhausted. All limit reinstatements thereafter require no additional
premium. Effective October 1, 2021, limits can be reinstated a maximum of four
times.

(2) Prior to October 1, 2020, retention was $1M.

(3) Historically, retention has ranged from 2.5% to 32.5%.

(4) Historically, retention has ranged from $1M to $2M.

(5) Includes an AAD where retention is 3.5% of subject earned premium in annual
losses otherwise recoverable in excess of the $500K retention per loss
occurrence.


Large HCPL risks that are above the limits of our basic reinsurance treaties may
be reinsured on a facultative basis, whereby the reinsurer agrees to insure a
particular risk up to a designated limit. We also have in place a number of risk
sharing arrangements that apply to the first $1 million of losses for certain
large healthcare systems and other insurance entities, as well as with certain
insurance agencies that produce business for us.

Other Reinsurance Arrangements


For the workers' compensation business ceded to Inova Re and Eastern Re, each
SPC has in place its own reinsurance arrangements; which are illustrated in the
following table.

                     Segregated Portfolio Cell Reinsurance

                    Per Occurrence Coverage       Aggregate Coverage

(1) The attachment point is based on a percentage of written premium within
individual cells, ranges from 85% to 94%, and varies by cell.


Each SPC has participants and the profit or loss of each cell accrues fully to
these cell participants. As previously discussed, we participate in certain SPCs
to a varying degree. Each SPC maintains a loss fund initially equal to the
difference between premium assumed by the cell and the ceding commission. The
external participants of each cell provide collateral to us, typically in the
form of a letter of credit that is initially equal to the difference between the
loss fund of the SPC (amount of funds available to pay losses after deduction of
ceding commission) and the aggregate attachment point of the reinsurance. Over
time, an SPC's retained profits are considered in the determination of the
collateral amount required to be provided by the cell's external participants.

Within our Lloyd's Syndicates segment, Syndicate 1729 utilizes reinsurance to
provide capacity to write larger limits of liability on individual risks, to
provide protection against catastrophic loss and to provide protection against
losses in excess of policy limits. The level of reinsurance that Syndicate 1729
purchases is dependent on a number of factors, including its underwriting risk
appetite for catastrophic exposure, the specific risks inherent in each line or
class of business written and the pricing, coverage and terms and conditions
available from the reinsurance market. Reinsurance protection by line of
business is as follows:

•Reinsurance is utilized on a per risk basis for the property insurance and
casualty coverages in order to mitigate risk volatility.
•Catastrophic protection is utilized on both our property insurance and casualty
coverages to protect against losses in excess of policy limits as well as
natural catastrophes.
•Both quota share reinsurance and excess of loss reinsurance are utilized to
manage the net loss exposure on our property reinsurance coverages.
•Property umbrella excess of loss reinsurance is utilized for peak catastrophe
and frequency of catastrophe exposures.

  Table of Contents
•Prior to January 1, 2022, external excess of loss reinsurance was utilized by
Syndicate 1729 to manage the net loss exposure on the specialty property and
contingency coverages ceded to Syndicate 6131; Syndicate 6131 ceased
underwriting on a quota share basis with Syndicate 1729 as Syndicate 6131's
business was incorporated into Syndicate 1729 beginning with the 2022 year of
account. For the second half of 2020, external quota share reinsurance was
utilized by Syndicate 6131 to manage the net loss exposure on the specialty
property and contingency coverages it assumed from Syndicate 1729 by ceding
essentially half of the premium assumed to an unaffiliated insurer; this
agreement was non-renewed on January 1, 2021 (see further discussion in the
Segment Results - Lloyd's Syndicates section that follows).

Syndicate 1729 may still be exposed to losses that exceed the level of
reinsurance purchased as well as to reinstatement premiums triggered by losses
exceeding specified levels. Cash demands on Syndicate 1729 can vary
significantly depending on the nature and intensity of a loss event. For
significant reinsured catastrophe losses, the inability or unwillingness of the
reinsurer to make timely payments under the terms of the reinsurance agreement
could have an adverse effect on Syndicate 1729's liquidity.

Taxes


We are subject to the tax laws and regulations of the U.S., Cayman Islands and
U.K. We file a consolidated U.S. federal income tax return that includes the
parent company and its U.S. subsidiaries, except for ProAssurance American
Mutual, a Risk Retention Group. Our filing obligations include a requirement to
make quarterly payments of estimated taxes to the IRS using the corporate tax
rate effective for the tax year. We did not make any quarterly estimated tax
payments during the year ended December 31, 2021 or 2020.

As a result of the CARES Act that was signed into law on March 27, 2020, as
previously discussed, we were permitted to carryback NOLs generated in tax years
2019 and 2020 for up to five years. See further discussion in Note 7 of the
Notes to Consolidated Financial Statements. We generated an NOL of approximately
$33.3 million from the 2020 tax year that was carried back to the 2015 tax year
that resulted in a claim for a refund of approximately $11.7 million, which we
anticipate to receive during the first half of 2022. Additionally, we had an NOL
of approximately $25.6 million from the 2019 tax year which was carried back to
the 2014 tax year and generated a tax refund of approximately $9.0 million which
we received in February 2021. Furthermore, we received a tax refund of $1.3
million during the second quarter of 2021 due to the repeal of a previous
election we made under the TCJA related to discounted loss reserves.

As a result of our acquisition of NORCAL, we recorded $46.8 million of net
deferred tax assets reflecting the remeasurement of NORCAL's historical net
deferred tax assets. The net deferred tax assets acquired from NORCAL were
subject to recalculation following application of all purchase accounting
adjustments and our assessment of the realizability of NORCAL's deferred tax
assets. As a result of the NORCAL acquisition, we have U.S. federal NOL
carryforwards which as of December 31, 2021 were approximately $43.0 million.
These NOL carryforwards are subject to limitation by Internal Revenue Code
Section 382 and will begin to expire in 2035.

A detailed listing of our investment holdings as of December 31, 2021 is located
under the Financial Information heading on the Investor Relations page of our
website which can be reached directly at
https://investor.proassurance.com/financial-information/quarterly-investment-supplements/default.aspx
or through links from the Investor Relations section of our website,
investor.proassurance.com.

We manage our investments to ensure that we will have sufficient liquidity to
meet our obligations, taking into consideration the timing of cash flows from
our investments, including interest payments, dividends and principal payments,
as well as the expected cash flows to be generated by our operations.
Furthermore, we managed our investments as part of our capital planning in
anticipation of closing our acquisition of NORCAL. In addition to the interest
and dividends we will receive from our investments, we anticipate that between
$70 million and $130 million of our portfolio will mature (or be paid down) each
quarter over the next twelve months and become available, if needed, to meet our
cash flow requirements. The primary outflow of cash at our insurance
subsidiaries is related to paid losses and operating costs, including income
taxes. The payment of individual claims cannot be predicted with certainty;
therefore, we rely upon the history of paid claims in estimating the timing of
future claims payments with consideration to current and anticipated industry
trends and macroeconomic conditions. To the extent that we may have an
unanticipated shortfall in cash, we may either liquidate securities or borrow
funds under existing borrowing arrangements through our Revolving Credit
Agreement and the FHLB system. Permitted borrowings under our Revolving Credit
Agreement are $250 million with the possibility of an additional $50 million
accordion feature, if successfully subscribed. Given the duration of our
investments, we do not foresee a shortfall that would require us to meet
operating cash needs through additional borrowings. Additional information
regarding our Revolving Credit Agreement is detailed in Note 13 of the Notes to
Consolidated Financial Statements.

At December 31, 2021, our FAL was comprised of fixed maturity securities with a
fair value of $36.6 million and cash and cash equivalents of $1.2 million
deposited with Lloyd's. See further discussion in Note 4 of the Notes to
Consolidated Financial Statements. During the second and fourth quarters of
2021, we received a return of approximately $24.5 million and $8.0 million,
respectively, of cash from our FAL balances given the reduction in our
participation in the results of Syndicate 1729 and Syndicate 6131 for the 2021
underwriting year. Further, during the fourth quarter of 2021, ProAssurance
received a return of approximately $26.6 million of cash from our FAL balances
given Syndicate 6131 ceased underwriting on a quota share basis with Syndicate
1729 as Syndicate 6131's business is retained within Syndicate 1729 beginning
with the 2022 underwriting year. See further discussion on the return of FAL in
the Segment Results - Lloyd's Syndicates section that follows.

Our investment portfolio continues to be primarily composed of high quality
fixed income securities with approximately 92% of our fixed maturities being
investment grade securities as determined by national rating agencies. The
weighted average effective duration of our fixed maturity securities at
December 31, 2021 was 3.71 years; the weighted average effective duration of our
fixed maturity securities combined with our short-term securities was 3.51
years.

The carrying value and unfunded commitments for certain of our investments were

Investment fund LPs/LLCs are by nature less liquid and may involve more risk
than other investments. We manage our risk through diversification of asset
class and geographic location. At December 31, 2021, we had investments in 34
separate investment funds with a total carrying value of $323.2 million which
represented approximately 7% of our total investments. Our investment fund
LPs/LLCs generate earnings from trading portfolios, secured debt, debt
securities, multi-strategy funds and private equity investments, and the
performance of these LPs/LLCs is affected by the volatility of equity and credit
markets. For our investments in LPs/LLCs, we record our allocable portion of the
partnership operating income or loss as the results of the LPs/LLCs become
available, typically following the end of a reporting period.

Business Combinations and Ventures


On May 5, 2021, we completed the acquisition of NORCAL by purchasing 98.8% of
the converted company stock in exchange for total consideration transferred of
$449 million. On September 16, 2021, we acquired the remaining 1.2% interest in
NORCAL for $3 million of cash. On May 5, 2021, ProAssurance funded the
transaction with $248 million of cash on hand and NORCAL paid $2 million to
policyholders who elected to receive the discounted cash option for their
allocated share of the converted company's equity. Additional consideration with
a principal amount of $191 million and a fair value of $175 million, is in the
form of Contribution Certificates issued to certain NORCAL policyholders in the
conversion, and those instruments are an obligation of NORCAL Insurance Company,
the successor of NORCAL Mutual Insurance Company (see Note 13 of the Notes to
Consolidated Financial Statements for further discussion of the terms of the
Contribution Certificates). Policyholders who tendered NORCAL stock to
ProAssurance are also eligible for a share of contingent consideration in an
amount of up to approximately $84 million depending upon the after-tax
development of NORCAL's ultimate net losses between December 31, 2020 and
December 31, 2023. The estimated fair value of this contingent consideration was
$24 million as of May 5, 2021 and December 31, 2021. The Agreement and Plan of
Acquisition is included as Exhibit 2.1 of this report. Additional information
regarding our acquisition of NORCAL is included in Note 2 of the Notes to
Consolidated Financial Statements. There were no business combinations during
the year ended December 31, 2020.

     Second Quarter       $           0.05                                $ 0.05      $ 0.31

Each dividend was paid in the month following the quarter in which it was
declared. Cash dividends totaling $11 million, $39 million and $93 million were
paid during the years ended December 31, 2021, 2020 and 2019, respectively. Any
decision to pay future cash dividends is subject to the Board's final
determination after a comprehensive review of financial performance, future
expectations and other factors deemed relevant by the Board.

Debt


At December 31, 2021, our debt included $250 million of outstanding unsecured
senior notes. The notes bear interest at 5.3% annually and are due in 2023
although they may be redeemed in whole or part prior to maturity. There are no
financial covenants associated with these notes.

NORCAL Insurance Company, successor to NORCAL Mutual Insurance Company, issued
Contribution Certificates, which bear interest at 3.0% annually and are due in
2031, to certain NORCAL policyholders in the conversion. The Contribution
Certificates have a principal amount of $191 million and were recorded at their
fair value of $175 million at the date of the NORCAL acquisition. The difference
of $16 million between the recorded acquisition date fair value and the
principal balance of the Contribution Certificates will be accreted utilizing
the effective interest method over the term of the certificates of ten years as
an increase to interest expense. Furthermore, interest payments, which begin in
April 2022, are subject to deferral if we do not receive permission from the
California Department of Insurance prior to payment. See Note 2 and Note 13 of
the Notes to Consolidated Financial Statements for additional information on the
Contribution Certificates issued in the NORCAL acquisition. There are no
financial covenants associated with these certificates.

We have a Revolving Credit Agreement, which expires in November 2024, that may
be used for general corporate purposes, including, but not limited to,
short-term working capital, share repurchases as authorized by the Board and
support for other activities. Our Revolving Credit Agreement permits borrowings
of up to $250 million as well as the possibility of a $50 million accordion
feature, if successfully subscribed. At December 31, 2021, there were no
outstanding borrowings on our Revolving Credit Agreement; we are in compliance
with the financial covenants of the Revolving Credit Agreement.

Two of our subsidiaries, ProAssurance Indemnity Company, Inc. and ProAssurance
Insurance Company of America, had Mortgage Loans with one lender in connection
with the recapitalization of two office buildings, with scheduled maturities in
December 2027. The Mortgage Loans accrued interest at three-month LIBOR plus
1.325% with principal and interest payable on a quarterly basis. During 2021, we
repaid the balance outstanding on the Mortgage Loans of approximately $35.3
million. Interest expense on the Mortgage Loans during the year ended
December 31, 2021 included the write-off of the unamortized debt issuance costs
which were nominal in amount.

Additional information regarding our debt is provided in Note 13 of the Notes to
Consolidated Financial Statements.


Three of our insurance subsidiaries are members of an FHLB. Through membership,
those subsidiaries have access to secured cash advances which can be used for
liquidity purposes or other operational needs. In order for us to use FHLB
proceeds, regulatory approvals may be required depending on the nature of the
transaction. To date, those subsidiaries have not materially utilized their
membership for borrowing purposes.

For the year ended December 31, 2021, consolidated net premiums earned included
additional earned premiums of $214.6 million in our Specialty P&C segment from
our acquisition of NORCAL. Excluding NORCAL, consolidated net premiums earned
decreased $35.6 million in 2021 as compared to 2020 driven by a decrease in net
premiums earned in our Lloyd's Syndicates and Workers' Compensation Insurance
segments, partially offset by an increase in net premiums earned in our
Specialty P&C segment. The decrease in our Lloyd's Syndicates segment was due to
our decreased participation in the results of Syndicate 1729 and Syndicate 6131
for the 2021 underwriting year. For both our Workers' Compensation Insurance and
Segregated Portfolio Cell Reinsurance segments, the decrease in net premiums
earned reflected the competitive workers' compensation market conditions and,
for our Workers' Compensation Insurance segment, the impact of audit premium
returned to policyholders. Net premiums earned in our Specialty P&C segment,
excluding NORCAL, increased in 2021 due to the beneficial impacts of our
re-underwriting efforts and focus on rate adequacy, partially offset by the
prior year effect of a tail policy associated with a large national healthcare
account which resulted in $14.3 million of one-time premium written and fully
earned during the second quarter of 2020.

The following table shows our consolidated net investment result:

*Equity in earnings (loss) of unconsolidated subsidiaries includes our share of the operating results of interests we
hold in certain LPs/LLCs as well as operating losses associated with our tax credit partnership investments, which are
designed to generate returns in the form of tax credits and tax-deductible project operating losses.


Our consolidated net investment result for the year ended December 31, 2021
included additional net investment income of $13.1 million from NORCAL.
Excluding NORCAL, consolidated net investment income decreased $14.6 million for
the year ended December 31, 2021 as compared to 2020 driven by lower yields on
our corporate debt securities and short-term investments given the continued low
interest rate environment and, to a lesser extent, lower income from our equity
portfolio due to a decrease in our allocation to this asset category during the
first half of 2021. Furthermore, the decline in net investment income during
2021 reflected the impact of capital planning in anticipation of closing the
NORCAL acquisition. The increase in our investment results from our portfolio of
investments in LPs/LLCs for 2021 as compared to 2020 was due to higher earnings
from several of our LPs/LLCs and the prior year effect of the volatility in the
global financial markets related to COVID-19. Our consolidated net investment
result for 2021 also included additional earnings from our acquired interests in
four LPs from NORCAL of approximately $1.4 million; given the results of our
investments in LPs/LLCs are often reported to us on a one quarter lag, the
earnings from these investments were not reflected in our results until the
third quarter of 2021.

Table of Contents


Excluding the impact of the items specifically identified in the table above,
our consolidated current accident year net loss ratio for the year ended
December 31, 2021 decreased 2.3 percentage points driven by our Specialty P&C
and Lloyd's Syndicates segments, somewhat offset by a higher ratio in our
Workers' Compensation Insurance segment. The improvement in the current accident
year net loss ratio in our Specialty P&C segment was driven by decreases to
certain loss ratios during the first quarter of 2021 in our Standard Physician
and Specialty lines of business as we continue to recognize the beneficial
impacts of our re-underwriting efforts and focus on rate adequacy. In addition,
we observed a reduction in claims frequency in 2020 in our Specialty P&C segment
that continued into 2021, some of which is due to our re-underwriting efforts
while some of which we believe is associated with the COVID-19 pandemic
including the disruption of the court systems. Given the consistent and
prolonged nature of this favorable claims frequency trend, we further reduced
certain loss ratios in our Standard Physician line of business during the third
and fourth quarters of 2021. For our Lloyd's Syndicates segment, the lower
current accident year net loss ratio reflected higher reinsurance recoveries as
a proportion of gross losses as compared to the prior year period, partially
offset by certain catastrophe related losses. In our Workers' Compensation
Insurance segment, the increase in the current accident year loss ratio
primarily reflects workers returning to full employment after the lifting of
pandemic-related restrictions and the labor shortage. We have experienced an
increase in reported claim activity in 2021, including increased
severity-related claim activity, which we attribute to workers being out of
"work shape" as they returned to employment in 2021 as well as the lack of
training, alternative work arrangements and employee fatigue due to the labor
shortage.

Initial loss ratios associated with NORCAL policies were higher than the average
for the other books of business in our Specialty P&C segment; however, we
reduced certain NORCAL loss ratios during the fourth quarter of 2021 due to
favorable frequency trends, as previously discussed. The net impact of NORCAL
operations resulted in a 2.7 percentage point increase in our consolidated
current accident year net loss ratio in 2021. Also as a result of our
acquisition of NORCAL, our consolidated current accident year loss ratio during
2021 was impacted by amortization of the negative VOBA associated with NORCAL's
assumed unearned premium which is recorded as a reduction to current accident
year net losses and accounted for a 0.9 percentage point decrease in our
consolidated current period ratio. See Note 2 of the Notes to Consolidated
Financial Statements for additional information on the NORCAL acquisition and
the related purchase accounting adjustments. During 2020, our consolidated
current accident year loss ratio was higher due to the effect of a large
national healthcare account, net of the impact of related PDR amortization,
which accounted for 5.9 percentage points of the decrease in the current period
ratio as compared to the prior year period. In addition, our consolidated
current accident year loss ratio for 2020 was impacted by a $10 million IBNR
reserve we recorded during the second quarter of 2020 for COVID-19 which
accounted for 1.3 percentage points of the decrease in the ratio as compared to
the prior year period.

In both 2021 and 2020, our consolidated calendar year net loss ratio was lower
than our consolidated current accident year net loss ratio due to the
recognition of net favorable prior year reserve development, as shown in the
previous table. The net favorable loss development recognized in 2021 primarily
reflected a lower than anticipated claims severity trend (i.e., the average size
of a claim) in our Specialty P&C segment, primarily related to the 2015 through
2020 accident years. For our Workers' Compensation Insurance and Segregated
Portfolio Cell Reinsurance segments, the net favorable development in 2021
reflected overall favorable trends in claim closing patterns. Further, favorable
development recognized in 2021 included $7.9 million related to the amortization
of the purchase accounting fair value adjustment on NORCAL's assumed net reserve
and amortization of the negative VOBA associated with NORCAL's DDR reserve which
is recorded as a reduction to prior accident year net losses and loss adjustment
expenses. We have not recognized any development related to NORCAL's prior
accident year reserves since the date of acquisition in 2021. See Note 2 of the
Notes to Consolidated Financial Statements for additional information on the
NORCAL acquisition and the related purchase accounting adjustments. We also
recognized favorable prior year reserve development of $1 million during the
third quarter of 2021 in our Specialty P&C segment associated with our COVID-19
IBNR reserve due to the fact that early first notices have not materialized into
claims. We continue to remain cautious in our evaluation of our reserves our
Specialty P&C segment due to the uncertainty surrounding the length and severity
of the pandemic. See additional discussion on our COVID-19 IBNR reserve in the
Critical Accounting Estimates section under the heading "Reserve for Losses and
Loss Adjustment Expenses".

The change in our consolidated underwriting expense ratio for the year ended
December 31, 2021 as compared to 2020 was primarily attributable to the
following:

(2) See previous discussion under the heading "Revenues"


Our consolidated underwriting expense ratio for 2021 was impacted by our
acquisition of NORCAL. The additional expenses of NORCAL of $19.3 million had
only a nominal effect on the consolidated underwriting expense ratio as they
were more than offset by the favorable effect on the ratio of NORCAL net
premiums earned of $214.6 million, as previously discussed. The impact of NORCAL
decreased our consolidated underwriting expense ratio for 2021 by 5.3 percentage
points. Included in NORCAL's expenses for 2021 was approximately $9.4 million of
DPAC amortization associated with NORCAL policies written subsequent to our
acquisition; however, this level of DPAC amortization is approximately $13.4
million lower than would be considered normal for the period of time
post-acquisition due to the application of GAAP purchase accounting rules
whereby the capitalized policy acquisition costs for policies written prior to
the acquisition date were written off through purchase accounting rather than
being expensed pro rata over the remaining term of the associated policies.
Normalizing this amortization would have increased our consolidated expense
ratio in 2021 by an estimated 1.4 percentage points. Please see Note 2 of the
Notes to Consolidated Financial Statements for additional information on the
NORCAL acquisition. For 2021, our consolidated underwriting expense ratio was
also impacted by transaction-related costs of $25.0 million associated with our
acquisition of NORCAL which accounted for an increase of 2.6 percentage points
in our current period ratio. We do not consider transaction-related costs in
assessing the financial performance of our segments, and thus these costs are
only included in our consolidated operating expenses. Please see Note 18 of the
Notes to Consolidated Financial Statements for a reconciliation of our segment
results to our consolidated results. Excluding the impact of NORCAL and the
other items specifically identified in the table above, our consolidated
underwriting expense ratio remained relatively unchanged in 2021 as compared to
2020.

For the year ended December 31, 2021, the underwriting expense ratios in our
Specialty P&C and Corporate segments also reflected the impact of a reduction to
the management fee charged to the operating subsidiaries of our Specialty P&C
segment (excluding the acquired operating subsidiaries of NORCAL) by our
Corporate segment effective January 1, 2021 (see further discussion in our
Segment Results - Specialty Property & Casualty and Segment Results - Corporate
sections that follow). This change had no impact to our consolidated
underwriting expense ratio.

Gain on Bargain Purchase


As a result of the NORCAL acquisition, we recognized a non-taxable preliminary
gain on bargain purchase of $74.4 million during the second quarter of 2021
representing the excess of the fair value of the identifiable assets acquired
and liabilities assumed over the purchase consideration. We do not consider this
gain in assessing the financial performance of any of our operating or
reportable segments and therefore, we have excluded it from the Segment Results
sections that follow. See further discussion around the gain on bargain purchase
recognized from the NORCAL acquisition in Note 2 of the Notes to Consolidated
Financial Statements.

Taxes

Our effective tax rates for the years ended December 31, 2021 and 2020 were as
follows:

                                                         Year Ended December 31

Income (loss) before income taxes $ 146,607 $ (217,056) $ 363,663 167.5%

      Income tax expense (benefit)            2,483         (41,329)         43,812     106.0%
      Net income (loss)                   $ 144,124      $ (175,727)     $  319,851     182.0%

We recognized income tax expense in 2021 of $2.5 million and an income tax
benefit of $41.3 million in 2020. The most significant item impacting our
effective tax rate for the year ended December 31, 2021, which caused it to be
lower than the statutory federal income tax rate of 21%, was the aforementioned
non-taxable $74.4 million gain on bargain purchase related to the NORCAL
acquisition. Additionally, our effective tax rates for the years ended
December 31, 2021 and 2020 include the benefit recognized from the tax credits
transferred to us from our tax credit partnership investments. Our effective tax
rate in 2020 was also impacted by the non-deductible portion of the goodwill
impairment related to the Specialty P&C reporting unit recognized during the
third quarter of 2020. See further discussion of the goodwill impairment in the
Critical Accounting Estimates section under the heading "Goodwill / Intangibles"
and Note 8 of the Notes to Consolidated Financial Statements and further
information on other notable items impacting our effective tax rates for the
years ended December 31, 2021 and 2020 in the Segment Results - Corporate
section that follows under the heading "Taxes."

Operating Ratio


Our operating ratio is our combined ratio, less our investment income ratio.
This ratio provides the combined effect of underwriting profitability and
investment income. Our operating ratio for the years ended December 31, 2021 and
2020 was as follows:

                                                                                 Year Ended December 31

*Our consolidated combined ratio as reported in 2021 includes $25.0 million of transaction-related costs included in
consolidated operating expenses associated with our acquisition of NORCAL. Given these costs do not reflect normal operating
expenses we have excluded their impact from our calculation of the consolidated combined ratio in the table above. See
previous discussion under the heading "Expenses."


The primary drivers of the change in our operating ratio were as follows:

                                                                                          Increase (Decrease)

(1) See previous discussion under the heading "Revenues" and "Expenses."
(2) Excludes net investment income contributed by NORCAL since the date of
acquisition. See previous discussion under the heading "Revenues."



Excluding the impact of the items specifically identified in the table above,
our operating ratio for 2021 decreased by 3.5 percentage points as compared to
2020 primarily due to an improvement in the net loss ratio in our Specialty P&C
segment, partially offset by a higher net loss ratio in our Workers'
Compensation Insurance segment. See previous discussion in this section under
the heading "Expenses" and further discussion in our Segment Operating Results
sections that follow.

ROE

ROE is calculated as net income (loss) divided by the average of beginning and
ending shareholders' equity. This ratio measures our overall after-tax
profitability and shows how efficiently capital is being used. The $74.4 million
gain on bargain purchase recognized during the second quarter of 2021 was
excluded in our calculation of ROE for 2021 consistent with our treatment of
gains on bargain purchases from previous acquisitions. ROE for the years ended
December 31, 2021 and 2020 was as follows:

                                     Year Ended December 31
                                   2021           2020      Change
                      ROE               5.3  %  (12.3  %)  17.6   pts


Our ROE in 2021 was impacted by our acquisition of NORCAL. NORCAL operations
since the date of acquisition, excluding purchase accounting adjustments,
decreased our ROE in 2021 by 0.6 percentage points largely due to the fact that
loss ratios associated with NORCAL policies are higher than the average for the
other books of business in our Specialty P&C segment, partially offset by a
lower than normal amount of DPAC amortization due to the application of GAAP
purchase

accounting rules (see previous discussion under the heading "Expenses").
Furthermore, the remaining purchase accounting adjustments associated with the
acquisition increased our ROE by 1.1 percentage points. See Note 2 of the Notes
to Consolidated Financial Statements for additional information on the NORCAL
acquisition and the related purchase accounting adjustments. Excluding the
NORCAL acquisition, ROE for 2021 increased 17.1 percentage points driven by the
prior year effect of a $161.1 million pre-tax goodwill impairment recognized
related to the Specialty P&C reporting unit during the third quarter of 2020.
Additionally, the increase in our ROE for 2021 as compared to 2020, excluding
NORCAL, reflected higher earnings from certain LPs/LLCs, realized gains from the
sale of certain available-for-sale fixed maturity securities and other
investments as well as improved underwriting results.

Book Value per Share


Book value per share is calculated as total shareholders' equity at the balance
sheet date divided by the total number of common shares outstanding. This ratio
measures the net worth of the Company to shareholders on a per share basis. Our
book value per share at December 31, 2021 as compared to December 31, 2020 is
shown in the following table.

                                                                          Book Value Per Share

Non-GAAP Financial Measures

Non-GAAP operating income (loss) is a financial measure that is widely used to
evaluate performance within the insurance sector. In calculating Non-GAAP
operating income (loss), we have excluded the effects of the items listed in the
following table that do not reflect normal results. We believe Non-GAAP
operating income (loss) presents a useful view of the performance of our
insurance operations, however it should be considered in conjunction with net
income (loss) computed in accordance with GAAP.

The following table is a reconciliation of net income (loss) to Non-GAAP
operating income (loss):

(1) Net investment gains (losses) on investments related to SPCs are recognized
in our Segregated Portfolio Cell Reinsurance segment. SPC results, including any
net investment gain or loss, that are attributable to external cell participants
are reflected in the SPC dividend expense (income). To be consistent with our
exclusion of net investment gains (losses) recognized in earnings, we are
excluding the portion of net investment gains (losses) that is included in the
SPC dividend expense (income) which is attributable to the external cell
participants.

(2) Transaction-related costs associated with our acquisition of NORCAL. We are
excluding these costs as they do not reflect normal operating results and are
unique and non-recurring in nature.

(3) Gain on bargain purchase associated with our acquisition of NORCAL which is
considered unusual, infrequent and non-recurring in nature. As such, we have
excluded the gain on bargain purchase from Non-GAAP operating income (loss) as
it does not reflect normal operating results.

(4) The 21% rate is the statutory tax rate associated with the taxable or tax
deductible items listed above. The taxes associated with the net investment
gains (losses) related to SPCs in our Segregated Portfolio Cell Reinsurance
segment are paid by the individual SPCs and are not included in our consolidated
tax provision or net income (loss); therefore, both the net investment gains
(losses) from our Segregated Portfolio Cell Reinsurance segment and the
adjustment to exclude the portion of net investment gains (losses) included in
the SPC dividend expense (income) in the table above are not tax effected. The
2021 gain on bargain purchase is non-taxable and therefore had no associated
income tax impact. The portion of 2020 goodwill impairment loss that is tax
deductible was tax effected at the statutory tax rate (21%). The remaining
portion of the 2020 goodwill impairment loss is not tax deductible and therefore
had no associated income tax benefit.

Segment Results - Specialty Property & Casualty


Our Specialty P&C segment focuses on professional liability insurance and
medical technology liability insurance as discussed in Note 19 of the Notes to
Consolidated Financial Statements. On May 5, 2021, we completed our acquisition
of NORCAL, an underwriter of healthcare professional liability insurance (Note 2
of the Notes to Consolidated Financial Statements provides additional
information regarding this acquisition). Segment results reflected pre-tax
underwriting profit or loss from these insurance lines, including the pre-tax
underwriting results of NORCAL since the date of acquisition as well as certain
purchase accounting adjustments. Segment results for the year ended December 31,
2021 exclude transaction-related costs and a $74.4 million gain on bargain
purchase related to the NORCAL acquisition as we do not consider these items in

Premiums Written

Changes in our premium volume within our Specialty P&C segment are generally
driven by four primary factors: (1) the amount of new business written, (2) our
retention of existing business, (3) the premium charged for business that is
renewed, which is affected by rates charged and by the amount and type of
coverage an insured chooses to purchase and (4) the timing of premium written
through multi-period policies. In addition, premium volume may periodically be
affected by shifts in the timing of renewals between periods. For the year ended
December 31, 2021, our premium volume was primarily affected by our acquisition
of NORCAL (see Note 2 of the Notes to Consolidated Financial Statements).

The professional liability market, which accounts for a majority of the revenues
in this segment, remains challenging as physicians continue joining hospitals or
larger group practices and are thus no longer purchasing individual or group
policies in the standard market. In addition, some competitors have chosen to
compete primarily on price; both factors may impact our ability to write new
business and retain existing business. Furthermore, the insurance and
reinsurance markets have historically been cyclical, characterized by extended
periods of intense price competition and other periods of reduced competition.
The professional liability area has been particularly affected by these cycles.
Underwriting cycles are generally driven by an excess of capacity available and
actively pursuing business that is deemed profitable. Changes in the frequency
and severity of losses may affect the cycles of the insurance and reinsurance
markets significantly. During "soft markets" where price competition is high and
underwriting profits are poor, growth and retention of business become
challenging which may result in reduced premium volumes.

(1) Standard Physician premium was our greatest source of premium revenues in
both 2021 and 2020 and is predominantly comprised of twelve month term policies.
The increase in twelve month term policies in 2021 as compared to 2020 was
driven by an increase in renewal pricing, the conversion of twenty-four month
term policies and, to a lesser extent, new business written, partially offset by
retention losses. In addition, twelve month term policies in 2020 included the
impact of premium credits granted as a result of the COVID-19 pandemic. Renewal
pricing increases during 2021 reflect the rising loss cost environment and new
business written reflects general market conditions. Retention losses in 2021
were largely attributable to the loss of two large policies totaling $5.9
million during the third quarter of 2021 due to the insureds' decision to enter
into captive arrangements and the loss of two large policies totaling $1.4
million during the first quarter of 2021 due to price competition. Retention
losses in 2021 also reflected our targeted state strategy to reassess our
underwriting appetite in certain unprofitable states. We will continue to
perform a detailed evaluation of venues, specialties and other areas to improve
our underwriting results. We also continue to focus on underwriting discipline
as we emphasize careful risk selection, rate adequacy, improved contract terms
and a willingness to walk away from business that does not fit our goal of
achieving a long-term underwriting profit. While retention for 2021 has
recovered somewhat from the impact of our re-underwriting efforts over the past
two years, it remains lower than our historical average for this line of
business as we continue to reevaluate certain states and set our rates to
reflect our observations of higher severity trends. Standard Physician premium
in 2020 also included twenty-four month term policies that were offered to
physician insureds in one selected jurisdiction. We ceased offering twenty-four
month term policies beginning in the second quarter of 2020, and the majority of
the policies that were up for renewal in 2021 were renewed to twelve month term
policies; however, a portion of the premium from 2020 related to policies that
will be subject to renewal and conversion in 2022.

(2) NORCAL Standard Physician premium represents premium contributed by NORCAL
since the date of acquisition and is comprised of three and twelve month term
policies. NORCAL Standard Physician premium in 2021 was

impacted by an increase in renewal pricing and, to a lesser extent, new business
written, partially offset by retention losses, including the loss of one large
policy during the second quarter of 2021.

(3) Custom Physician premium includes large complex physician groups,
multi-state physician groups and non-standard physicians and is written
primarily on an excess and surplus lines basis. The decrease in Custom Physician
premium in 2021 was driven by retention losses, including the loss of a $10.4
million policy due to price competition and the non-renewal of two large
policies totaling $7.3 million due to our focus on underwriting discipline. The
decrease in Custom Physician premium in 2021 also reflected the impact of the
dissolution of our arrangement with CAPAssurance as a result of our acquisition
of NORCAL, which also resulted in the loss of a large program and two large
policies in California totaling $10.2 million during the first quarter of 2021.
Partially offsetting the decrease in Custom Physician premium in 2021 was new
business written, including the addition of four large policies totaling $5.6
million, and, to a lesser extent, an increase in renewal pricing. Renewal
pricing increases for 2021 reflect the rising loss cost environment and new
business written reflects general market conditions. The retention rate in our
Custom Physician book in 2021 was lower than 2020 which also reflects the impact
of the aforementioned dissolution of our arrangement with CAPAssurance as well
as the loss of the $10.4 million policy due to price competition, which resulted
in a decrease to our Specialty retention rate of 13.6 percentage points. While
retention for 2021 has recovered somewhat from the impact of our re-underwriting
efforts over the past two years, it remains lower than our historical average
for this line of business as our rates are set to reflect our observations of
higher severity trends.

(4) NORCAL Custom Physician premium represents premium contributed by NORCAL
since the date of acquisition and includes large complex physician groups,
multi-state physician groups and non-standard physicians and is written
primarily on an excess and surplus lines basis. NORCAL Custom Physician premium
in 2021 was impacted by retention losses, including the loss of a $9.0 million
policy during the fourth quarter of 2021 due to price competition, partially
offset by an increase in renewal pricing and, to a lesser extent, new business
written.

(5) Hospitals and Facilities premium (which includes hospitals, surgery centers
and miscellaneous medical facilities) increased in 2021 as compared to 2020
driven by new business written, primarily miscellaneous medical facilities, and,
to a lesser extent, an increase in renewal pricing, partially offset by
retention losses. Renewal pricing increases in 2021 reflect rate increases and
contract modifications that we believe are appropriate given the current loss
environment and new business written reflects general market conditions.
Retention losses in 2021 were driven by the loss of a $2.3 million policy due to
price competition, the loss of a $2.0 million policy due to an insured's
decision to enter into a captive arrangement, and our decision not to renew
certain products. As we substantially completed our re-underwriting efforts on
this book of business as of the end of the third quarter of 2020, retention
rates have started to normalize.

(6) NORCAL Hospitals and Facilities premium represents premium contributed by
NORCAL since the date of acquisition and includes hospitals, surgery centers and
miscellaneous medical facilities. NORCAL Hospitals and Facilities premium in
2021 was impacted by retention losses, partially offset by new business written
and, to a lesser extent, an increase in renewal pricing.

(7) Senior Care premium includes facilities specializing in long term
residential care primarily for the elderly ranging from independent living
through skilled nursing. Our Senior Care premium remained relatively unchanged
in 2021 as compared to 2020 as retention losses were offset by new business
written and renewal pricing increases. The increase in renewal pricing in 2021
was primarily the result of an increase in the rate charged for certain renewed
policies in select states. Retention losses in 2021 were driven by our decision
not to renew certain classes of Senior Care business based on our expectations
of poor loss performance. As we completed our re-underwriting efforts on this
book of business during the third quarter of 2020, retention rates have started
to normalize.

(8) We offer custom alternative risk solutions including assumed reinsurance.
The increase in premium in 2021 primarily reflected an increase premiums assumed
on a quota share basis through a strategic partnership since 2016 with an
international medical professional liability insurer. For 2021, we increased our
participation in the original program and entered into another program with this
insurer in a new international territory. We anticipate the volume of premium
assumed through this partnership will continue to grow going forward. Our custom
alternative risk solutions in 2021 also include an assumed reinsurance
arrangement with a regional hospital group entered into during the first quarter
of 2021, which resulted in $4.5 million of premium written, comprised of $2.3
million of retroactive premium written and fully earned and $2.2 million of
prospective premium written. Furthermore, the increase in premium in 2021
reflected the annual renewal of this arrangement during the third quarter of
2021. See Note 5 of the Notes to Consolidated Financial Statements for further
information on this transaction.

(9) Our Small Business Unit is primarily comprised of premium associated with
podiatrists, legal professionals, dentists and chiropractors. Our Small Business
Unit premium increased in 2021 as compared to 2020 driven by an increase in
renewal pricing and, to a lesser extent, new business written, partially offset
by retention losses. The increase in renewal pricing in 2021 was primarily the
result of an increase in the rate charged for certain renewed policies in select
states.

(10) We offer extended reporting endorsement or "tail" coverage to insureds who
discontinue their claims-made coverage with us, and we also periodically offer
tail coverage through stand-alone policies. Tail coverage premiums are generally
100% earned in the period written because the policies insure only incidents
that occurred in prior periods and are not cancellable. The amount of tail
coverage premium written can vary significantly from period to period. The
decrease in 2021 as compared to 2020 was primarily due to the prior year effect
of a large national healthcare account that exercised its contractual option to
purchase tail coverage which resulted in $14.3 million of one-time premiums
written and fully earned in the second quarter of 2020. This impact was largely
offset by $7.8 million of tail premium written and fully earned during the
second quarter of 2021 associated with a Custom Physician policy and two large
tail policies totaling $2.1 million written and fully earned during the first
quarter of 2021.

(11) NORCAL Tail Coverages represent premium contributed by NORCAL since the
date of acquisition and include endorsement coverages to insureds who
discontinue their claims-made coverage and may also periodically include tail
coverage offered through stand-alone policies. As detailed in the previous
footnote, tail coverage premiums are generally 100% earned in the period written
and the amount of tail coverage premium written can vary significantly from
period to period. NORCAL Tail Coverages in 2021 included five large tail
policies totaling $4.5 million written and fully earned.

(12) Our Medical Technology Liability business is marketed throughout the U.S.;
coverage is typically offered on a primary basis, within specified limits, to
manufacturers and distributors of medical technology and life sciences products
including entities conducting human clinical trials. In addition to the
previously listed factors that affect our premium volume, our Medical Technology
Liability premium is also impacted by the sales volume of insureds. Our Medical
Technology Liability premium increased in 2021 as compared to 2020 due to new
business written and, to a lesser extent, an increase in renewal pricing,
partially offset by retention losses. Renewal pricing increases in 2021 are
primarily due to changes in the sales volume of certain insureds, including
changes in exposure. Retention losses in 2021 are primarily attributable to an
increase in competition on terms and pricing, as well as merger activity within
the industry.

(13) This component of gross premiums written includes all other product lines
within our Specialty P&C segment.


(14) Certain components of our gross premiums written include alternative market
premiums. We currently cede either all or a portion of the alternative market
premium, net of reinsurance, to three SPCs of our wholly owned Cayman Islands
reinsurance subsidiaries, Inova Re and Eastern Re, which are reported in our
Segregated Portfolio Cell Reinsurance segment (see further discussion in the
Ceded Premiums Written section that follows). The portion not ceded to the SPCs
is retained within our Specialty P&C segment.

The increase in alternative market gross premiums written in 2021 as compared to
2020 was driven by renewal pricing increases, primarily due to an increase in
the rate charged for one program and, to a lesser extent, the impact of tail
coverages.

We are committed to a rate structure that will allow us to fulfill our
obligations to our insureds, while generating competitive long-term returns for
our shareholders. Our pricing continues to be based on expected losses as
indicated by our historical loss data and available industry loss data. In
recent years, this practice has resulted in gradual rate increases and we
anticipate further rate increases due to indications of increasing loss
severity. Additionally, the pricing of our business includes the effects of
filed rates, surcharges and discounts. Renewal pricing also reflects changes in
our exposure base, deductibles,

For our Specialty P&C segment, we calculate retention as annualized renewed
premium divided by all annualized premium subject to renewal. Retention is
affected by a number of factors. We may lose insureds to competitors or to
alternative insurance mechanisms such as risk retention groups, captive
arrangements or self-insurance entities (often when physicians join hospitals or
large group practices) or due to pricing or other issues. We may choose not to
renew an insured as a result of our underwriting evaluation. Insureds may also
terminate coverage because they have left the practice of medicine for various
reasons, principally for retirement, death or disability, but also for personal
reasons.

Retention for our Specialty P&C segment, including by major component, was as
follows:

Ceded Premiums Written


Ceded premiums represent the amounts owed to our reinsurers for their assumption
of a portion of our losses. Our HCPL and Medical Technology Liability excess of
loss reinsurance arrangements renew annually on October 1. For those excess of
loss reinsurance arrangements in effect prior to October 1, 2021, we generally
retained the first $2 million in risk insured by us and ceded coverages in
excess of this amount. Effective October 1, 2021, our HCPL treaty renewed at a
lower gross rate and we generally retain from 0% to 5% of the next $24 million
of risk for our HCPL coverages in excess of $2 million. Our HCPL excess of loss
reinsurance arrangement that renewed on October 1, 2021 also incorporated NORCAL
policies. Prior to October 1, 2021, NORCAL policies were reinsured under
separate reinsurance agreements, primarily excess of loss, which have
historically renewed annually on January 1. For the NORCAL excess of loss
reinsurance arrangement that renewed on January 1, 2021, retention was generally
the first $2 million in risk and coverages in excess of this amount are ceded up
to $24 million. For our Medical Technology Liability treaty which also renewed
effective October 1, 2021, we also retain 2.5% of the next $8 million of risk
for coverages in excess of $2 million. There were no significant changes in the
cost or structure of our Medical Technology Liability treaty upon the October
2021 renewal.

We pay our reinsurers a ceding premium in exchange for their accepting the risk,
and in certain of our excess of loss arrangements, the ultimate amount of which
is determined by the loss experience of the business ceded, subject to certain
minimum and maximum amounts. Given the length of time that it takes to resolve
our claims, many years may elapse before all losses recoverable under a
reinsurance arrangement are known. As a part of the process of estimating our
loss reserve we also make estimates regarding the amounts recoverable under our
reinsurance arrangements. As a result, we may have an adjustment to our estimate
of expected losses and associated recoveries for prior year ceded losses under
certain loss sensitive reinsurance agreements. Any changes to estimates of
premiums ceded related to prior accident years are fully earned in the period
the changes in estimates occur.

Ceded premiums written were as follows:

(1)We generally reinsure risks under our excess of loss reinsurance arrangements
pursuant to which the reinsurers agree to assume all or a portion of all risks
that we insure above our individual risk retention levels, up to the maximum
individual limits offered. Premium due to reinsurers also fluctuates with the
volume of written premium subject to cession under the arrangement. In certain
of our excess of loss reinsurance arrangements, the premium due to the reinsurer
is determined by the loss experience of that business reinsured, subject to
certain minimum and maximum amounts. The decrease in ceded premiums written
under our excess of loss reinsurance arrangements in 2021 as compared to 2020
primarily reflected the reduced rate on the treaty year effective October 1,
2020 and, to a lesser extent, a decrease in the overall volume of gross premiums
written subject to cession. The decrease in ceded premiums written under our
excess of loss reinsurance arrangements in 2021 was partially offset by
additional ceded premiums of $1.9 million as a result of incorporating NORCAL
policies into our existing HCPL excess of loss reinsurance arrangements with the
October 1, 2021 renewal (see further discussion in footnote 4 below).

(2)We have entered into various shared risk arrangements, including quota share,
fronting and captive arrangements, with certain large healthcare systems and
other insurance entities. While we cede a large portion of the premium written
under these arrangements, they provide us an opportunity to grow net premium
through strategic partnerships. These arrangements primarily include our
Ascension Health program and, prior to the fourth quarter of 2020, our
CAPAssurance program. Our CAPAssurance program was mutually dissolved on October
1, 2020. During the first quarter of 2021, we entered into a new shared risk
arrangement with a regional hospital group. The decrease in ceded premiums
written under our shared risk arrangements in 2021 as compared to 2020 was
primarily due to the aforementioned dissolution of our arrangement with
CAPAssurance and, to a lesser extent, a decrease in premium ceded to our
Ascension Health Program, somewhat offset by the premium ceded under our new
shared risk arrangement, as previously discussed.

(3)As previously discussed, as a part of our alternative market solutions, all
or a portion of certain healthcare premium written is ceded to SPCs in our
Segregated Portfolio Cell Reinsurance segment under either excess of loss or
quota share reinsurance agreements, depending on the structure of the individual
program. See the Segment Results - Segregated Portfolio Cell Reinsurance section
for further discussion on the cession to the SPCs from our Specialty P&C
segment. The increase in premiums ceded to SPCs in 2021 as compared to 2020 was
driven by renewal pricing increases (see discussion in footnote 14 under the
heading "Gross Premiums Written").

(4)NORCAL policies written prior to September 30, 2021 were reinsured under
separate reinsurance agreements, primarily excess of loss; however, these
policies were incorporated into our existing HCPL excess of loss reinsurance
arrangements with the October 1, 2021 renewal, as previously discussed. For
NORCAL's previous excess of loss agreement, deposit ceded premium, as defined in
the contract, was initially estimated and recorded at the inception date of the
treaty, generally January 1, as an estimate of ceded premiums written for the
full contract year based on information provided by brokers and reinsurers. As a
result, the majority of ceded premiums for NORCAL's excess of loss reinsurance
arrangement was recorded by NORCAL before the acquisition in their first quarter
2021 results and were expensed pro rata throughout the contract year. However,
these initial estimates of ceded premiums may be periodically adjusted as new
information is received and are fully earned in the period the changes in
estimates occur. NORCAL's ceded premiums written since acquisition in 2021 under
these reinsurance arrangements related almost entirely to an increase in the
estimate of premiums owed in excess of the deposit ceded premium initially
recorded by NORCAL prior to acquisition and, to a lesser extent, premium related
to cyber liability coverages. Effective October 1, 2021, we incorporated NORCAL
policies into our existing HCPL excess of loss reinsurance arrangement, as
previously discussed.

(5)Given the length of time that it takes to resolve our claims, many years may
elapse before all losses recoverable under a reinsurance arrangement are known.
As a part of the process of estimating our loss reserve we also make estimates
regarding the amounts recoverable under our reinsurance arrangements. As
previously discussed, the premiums ultimately ceded under certain of our excess
of loss reinsurance arrangements are subject to the losses ceded under the
arrangements. As part of the review of our reserves for 2021, we decreased our
estimate of expected losses and associated recoveries for prior year ceded
losses, as well as our estimate of ceded premiums owed to reinsurers. In 2020,
we increased our estimate of expected losses and associated recoveries for prior
year ceded losses, as well as our estimate of ceded premiums owed to reinsurers
due to reaching the maximum level of premium due under certain prior year excess
of loss arrangements. Changes to estimates of premiums ceded related to prior
accident years are fully earned in the period the changes in estimates occur.

Ceded Premiums Ratio


As shown in the table below, our ceded premiums ratio was affected in both 2021
and 2020 by revisions to our estimate of premiums owed to reinsurers related to
coverages provided in prior accident years.

reinsurance agreements, prior accident years (as previously
discussed)

The above table reflects ceded premiums written, excluding the effect of prior
year ceded premium adjustments, as a percent of gross premiums written. Our
current accident year ceded premiums ratio for 2021 was impacted by the
inclusion of NORCAL ceded and written premiums since the date of acquisition,
which accounted for 1.7 percentage points of the decrease in the ratio as the
majority of ceded premiums for NORCAL's excess of loss reinsurance arrangements
were recorded before the acquisition, as previously discussed. Excluding the
impact of the NORCAL acquisition, our current accident year ceded premium ratio
for 2021 decreased 3.2 percentage points as compared to 2020. This decrease was
driven by a decrease in premiums ceded under our shared risk arrangements,
partially offset by the effect of a large national healthcare account tail
policy premium written during the second quarter of 2020. See further discussion
on NORCAL ceded premiums and our shared risk arrangements above under the
heading "Ceded Premiums Written."

Net Premiums Earned


Net premiums earned consist of gross premiums earned less the portion of earned
premiums that we cede to our reinsurers for their assumption of a portion of our
losses. Because premiums are generally earned pro rata over the entire policy
period, fluctuations in premiums earned tend to lag those of premiums written.
The majority of our policies carry a term of one year; however, some of our
Medical Technology Liability policies have a multi-year term and some of our
NORCAL Standard Physician policies have a three-month term. In addition, prior
to the third quarter of 2020, we wrote certain Standard Physician policies with
a twenty-four month term. Tail coverage premiums are generally 100% earned in
the period written because the policies insure only incidents that occurred in
prior periods and are not cancellable. Retroactive coverage premiums are 100%
earned at the inception of the contract, as all of the associated underlying
loss events occurred in the past. Additionally, any ceded premium changes due to
changes to estimates of premiums owed under reinsurance agreements for prior
accident years are fully earned in the period of change.

Net premiums earned were as follows:

217,643 45.6 %



Gross premiums earned in 2021 included additional earned premiums of
approximately $226.0 million from our acquisition of NORCAL. Of that amount of
earned premium, approximately $155.1 million was associated with NORCAL policies
written prior to our acquisition. Excluding premiums associated with the NORCAL
acquisition, gross premiums earned decreased $16.4 million in 2021 as compared
to 2020 driven by the pro rata effect of a decrease in the volume of written
premium during the preceding twelve months, predominantly in our Specialty line
of business, due to our re-underwriting efforts and, to a lesser extent, the
dissolution of our arrangement with CAPAssurance. The decrease in gross premiums
earned in 2021 also reflected premium adjustments related to loss sensitive
policies which decreased earned premium by $2.1 million and increased earned
premium by $2.9 million in 2020. In addition, the decrease in gross premiums
earned during 2021 reflected the prior year effect of a large national
healthcare account that exercised its contractual option to purchase tail
coverage which resulted in $14.3 million of one-time premiums written and fully
earned during the second quarter of 2020 (see previous discussion in footnote 10
under the heading "Gross Premiums Written"). The decrease in gross premiums
earned in 2021 was partially offset by tail premium associated with a Custom
Physician policy, which resulted in $7.8 million of one-time written and fully
earned during the second quarter of 2021 (see previous discussion in footnote 10
under the heading "Gross Premiums Written") and $2.3 million of retroactive
premium written and fully earned associated with an assumed reinsurance program
(see previous discussion in footnote 8 under the heading "Gross Premiums
Written").

Ceded premiums earned during 2021 included additional ceded premium of
approximately $11.4 million from our acquisition of NORCAL, which is primarily
attributable to subsequent adjustments made to initial deposit ceded premium
recorded under NORCAL's excess of loss reinsurance arrangement (see previous
discussion in footnote 4 under the heading "Ceded Premiums Written"). Excluding
ceded premiums from our NORCAL acquisition, ceded premiums earned decreased
$19.5 million in 2021 as compared to 2020 driven by the pro rata effect of a
decrease in premium ceded under our shared risk and excess of loss arrangements
during the preceding twelve months and, to a lesser extent, the effect of the
decrease in our estimate of ceded premiums owed to reinsurers for expected
recoveries on prior year ceded losses in 2021 as compared to an increase in our
estimate in 2020.

Losses and Loss Adjustment Expenses


The determination of calendar year losses involves the actuarial evaluation of
incurred losses for the current accident year and the actuarial re-evaluation of
incurred losses for prior accident years, including an evaluation of the reserve
amounts required for ECO/XPL losses.

Accident year refers to the accounting period in which the insured event becomes
a liability of the insurer. For claims-made policies, which represent the
majority of the premiums written in our Specialty P&C segment, the insured event
generally becomes a liability when the event is first reported to us. For
occurrence policies, the insured event becomes a liability when the event takes
place. For retroactive coverages, the insured event becomes a liability at
inception of the underlying contract. We believe that measuring losses on an
accident year basis is the best measure of the underlying profitability of the
premiums earned in that period, since it associates policy premiums earned with
the estimate of the losses incurred related to those policy premiums.

The following table summarizes calendar year net loss ratios for our Specialty
P&C segment by separating losses between the current accident year and all prior
accident years. Additionally, the table shows our current accident year net loss
ratios were affected by revisions to our estimate of premiums owed to reinsurers
related to coverages provided in prior accident years. Furthermore, net loss
ratios in the following table include the impact of NORCAL since the date of
acquisition.

prior accident years which decreased net premiums earned. See the discussion in

Excluding the impact of the items specifically identified in the table above,
our current accident year net loss ratio during 2021 improved 5.9 percentage
points driven by decreases to certain loss ratios during the first quarter of
2021 in our Standard Physician and Specialty lines of business as we continue to
recognize the beneficial impacts of our re-underwriting efforts and focus on
rate adequacy. In addition, we observed a reduction in claims frequency that
continued into 2021, some of which is due to our re-underwriting efforts while
some of which we believe is

associated with the COVID-19 pandemic including the disruption of the court
systems. Given the consistent and prolonged nature of this favorable claims
frequency trend, we further reduced certain loss ratios in our Standard
Physician line of business during the third and fourth quarters of 2021.


Initial loss ratios associated with NORCAL policies were higher than the average
for our other books of business in this segment; however, we reduced certain
NORCAL loss ratios during the fourth quarter of 2021 due to favorable frequency
trends, as previously discussed. The net impact of NORCAL operations resulted in
a 2.0 percentage point increase in our current accident year net loss ratio in
2021. We are currently in the process of evaluating the NORCAL book of business
and implementing ProAssurance's underwriting strategies. Also as a result of our
acquisition of NORCAL, our current accident year net loss ratio in 2021 was
impacted by amortization of the negative VOBA associated with NORCAL's assumed
unearned premium which is recorded as a reduction to current accident year net
losses and accounted for a 1.4 percentage point decrease in our current period
ratio. See Note 2 of the Notes to Consolidated Financial Statements for
additional information on the NORCAL acquisition and the related purchase
accounting adjustments. In addition, our current accident year net loss ratio in
2021 was impacted by changes in premium adjustments related to loss sensitive
policies which increased the current period ratio as compared to 2020 by 1.0
percentage point (see previous discussion under the heading "Net Premiums
Earned"). Our 2020 current accident year net loss ratio was higher due to the
effect of a large national healthcare account, net of the impact of related PDR
amortization, which accounted for 9.5 percentage points of the decrease in the
2021 ratio as compared to 2020. In addition, our current accident year net loss
ratio in 2020 was impacted by a $10 million IBNR reserve we recorded during the
second quarter of 2020 for COVID-19 which accounted for 2.2 percentage points of
the decrease in the 2021 ratio as compared to 2020.

We re-evaluate our previously established reserve each quarter based upon the
most recently completed actuarial analysis supplemented by any new analysis,
information or trends that have emerged since the date of that study. We also
take into account currently available industry trend information.

We recognized net favorable prior year accident reserve development of $32.9
million for the year ended December 31, 2021 as compared to $27.5 million for
the year ended December 31, 2020. Development recognized during 2021 primarily
reflected a lower than anticipated loss emergence, principally related to
accident years 2015 through 2020. Development recognized in 2020 principally
related to accident years 2014 through 2017. Net favorable prior accident year
reserve development recognized in 2021 included a $1.0 million reduction in our
IBNR reserve for COVID-19 during the third quarter of 2021 due to the fact that
early first notices have not materialized into claims. See additional discussion
on the COVID-19 IBNR reserve in the Critical Accounting Estimates section under
the heading "Reserve for Losses and Loss Adjustment Expenses". In addition, net
favorable prior accident year reserve development recognized in 2021 included an
increase for potential ECO/XPL claims of $1.0 million in 2021 as compared to a
reduction in the same reserve of $4.0 million in 2020. Furthermore, favorable
development recognized in 2021 included $7.9 million related to the amortization
of the purchase accounting fair value adjustment on NORCAL's assumed net reserve
and amortization of the negative VOBA associated with NORCAL's DDR reserve which
is recorded as a reduction to prior accident year net losses and loss adjustment
expenses. We have not recognized any development related to NORCAL's prior
accident year reserves since the date of acquisition.

A detailed discussion of factors influencing our recognition of loss development
is included in our Critical Accounting Estimates section under the heading
"Reserve for Losses and Loss Adjustment Expenses." Assumptions used in
establishing our reserve are regularly reviewed and updated by management as new
data becomes available. Any adjustments necessary are reflected in the then
current operations. Due to the size of our reserve, even a small percentage
adjustment to the assumptions can have a material effect on our results of
operations for the period in which the change is made, as was the case in both
2021 and 2020.

Underwriting, Policy Acquisition and Operating Expenses

Our Specialty P&C segment underwriting, policy acquisition and operating
expenses, including NORCAL expenses since the date of acquisition, were
comprised as follows:

Table of Contents


DPAC amortization for 2021 included approximately $9.4 million of DPAC
amortization associated with NORCAL policies written subsequent to our
acquisition; however, this level of DPAC amortization is approximately $13.4
million lower than would be considered normal for the period of time
post-acquisition due to the application of GAAP purchase accounting rules
whereby the capitalized policy acquisition costs for policies written prior to
the acquisition date were written off through purchase accounting rather than
being expensed pro rata over the remaining term of the associated policies (see
Note 2 of the Notes to Consolidated Financial Statements for more information).
Excluding NORCAL, DPAC amortization decreased for 2021 as compared to 2020
driven by a lower volume of premium written and a decrease in
compensation-related expenses driven by a reduction in headcount as a result of
the 2020 organizational restructuring. Partially offsetting the decrease in DPAC
amortization for 2021 was a decrease in ceding commission income, which is an
offset to expense, from certain of our shared risk arrangements.

Management fees are charged pursuant to a management agreement by the Corporate
segment to the operating subsidiaries within our Specialty P&C segment,
excluding the acquired operating subsidiaries of NORCAL, for services provided
based on the extent to which services are provided to the subsidiary and the
amount of premium written by the subsidiary. Fluctuations in the amount of
premium written by each subsidiary can result in corresponding variations in the
management fee charged to each subsidiary during a particular period. Due to
organizational structure enhancements in our Specialty P&C segment during 2020,
the extent to which services are provided by the Corporate segment to the
operating subsidiaries within the segment decreased effective January 1, 2021.
Accordingly, we reduced the fee charged to the operating subsidiaries in 2021.

Other underwriting and operating expenses increased in 2021 primarily due to the
addition of approximately $10.0 million of expenses contributed by NORCAL since
the date of acquisition and an increase in amortization related to new software
placed into service during the second quarter of 2020. In addition, the increase
in 2021 reflected higher amounts accrued for performance-related incentive plans
due to our improved combined ratio and other performance metrics. These
increases in expenses during 2021 were partially offset by lower operating
expenses in 2021 resulting from the operational and structural changes
implemented over the past two years as well as the effect of $3.4 million of
one-time expenses incurred during the prior year. One-time expenses in 2020 were
mainly comprised of early retirement benefits granted to certain employees
during the third quarter of 2020 as well as expenses associated with the
restructuring of our HCPL field office organization, largely during the first
half of 2020, consisting of employee severance charges and lease exit costs due
to a reduction in physical office locations. The remaining variance in other
underwriting and operating expenses for 2021 as compared to 2020 was comprised
of individually insignificant components.

Underwriting Expense Ratio (the Expense Ratio)

Our expense ratio for the Specialty P&C segment was as follows:


                                                    Year Ended December 31

addition, excludes certain one-time expenses included in DPAC amortization in 2020 of $0.6 million.
(2) See previous discussion under the heading "Gross Premiums Written."


Our underwriting expense ratio for 2021 was impacted by our acquisition of
NORCAL. The additional expenses of NORCAL of $19.3 million for 2021 had only a
nominal effect on the underwriting expense ratio as it was more than offset by
the favorable effect on the ratio of net premiums earned of $214.6 million
contributed by NORCAL which decreased our

--------------------------------------------------------------------------------

Table of Contents


Specialty P&C segment expense ratio for 2021 by 4.2 percentage points. However,
as previously discussed, DPAC amortization associated with NORCAL recorded
during 2021 was lower than would be considered normal due to the application of
GAAP purchase accounting rules. Normalizing this amortization would have
increased our expense ratio for 2021 by an estimated 1.9 percentage points.
Excluding the impact of NORCAL and the remaining items identified in the table
above, our expense ratio for 2021 increased by 0.6 percentage points primarily
due to the impact of an increase in amortization related to new software placed
into service during the second quarter of 2020 and higher amounts accrued for
performance-related incentive plans. These increases in 2021 as compared to 2020
were partially offset by decreased operating expenses resulting from the
operational and structural changes implemented over the past two years, as well
as the aforementioned reduction to the management fee charged by the Corporate
segment.

Segment Results - Workers' Compensation Insurance

Our Workers' Compensation Insurance segment includes workers' compensation
products provided to employers generally with 1,000 or fewer employees, as
discussed in Note 19 of the Notes to Consolidated Financial Statements. Workers'
compensation products offered include guaranteed cost policies, policyholder
dividend policies, retrospectively-rated policies, deductible policies and
alternative market programs. Alternative market programs include program design,
fronting, claims administration, risk management, SPC rental, asset management
and SPC management services. Alternative market program premiums are 100% ceded
to either the SPCs within our Segregated Portfolio Cell Reinsurance segment or,
to a limited extent, an unaffiliated captive insurer for one program. Our
Workers' Compensation Insurance segment results reflect pre-tax underwriting
profit or loss from these workers' compensation products, exclusive of
investment results, which are included in our Corporate segment. Segment results
included the following:

Premiums Written

Our workers' compensation premium volume is driven by five primary factors: (1)
the amount of new business written, (2) retention of our existing book of
business, (3) premium rates charged on our renewal book of business, (4) changes
in payroll exposure and (5) audit premium.

Gross, ceded and net premiums written were as follows:

(2) A majority of alternative market premiums are ceded to SPCs in our
Segregated Portfolio Cell Reinsurance segment. See further discussion on
alternative market gross premiums written in our Segment Operating Results -
Segregated Portfolio Cell Reinsurance section under the heading "Gross Premiums
Written" that follows.

Gross premiums written decreased during the year ended December 31, 2021 as
compared to 2020, reflecting a decrease in audit premium and new business,
partially offset by improvement in both renewal retention and renewal rate
changes. Policy audits processed during 2021 resulted in audit premium returned
to policyholders totaling $0.8 million as compared to audit premium billed to
policyholders of $0.6 million during 2020. We reduced our EBUB estimate by $1.2
million in 2021 as compared to $1.3 million in 2020. The decrease in audit
premium processed as well as the reduction of our EBUB estimate in 2021
primarily reflected the impact of COVID-19 on actual and expected final payroll
audits for policies written prior to the onset of the pandemic in 2020. Renewal
retention was 87% in 2021 as compared to 84% for 2020. The 2020 renewal
retention was impacted by the reduction in premium funding for a large
alternative market program. Renewal rate decreased 2% in 2021 as compared to 4%
in 2020. New business written decreased $6.3 million during 2021 as compared to
2020, reflecting the competitive workers' compensation market conditions and a
decrease in new business submissions in 2021, which were 18% lower than 2020.

We retained 23 of the 24 workers' compensation alternative market programs up
for renewal during the year ended December 31, 2021. During the fourth quarter
of 2021, we placed one program into run-off due to continued unfavorable
underwriting results. The program had gross written premium of $1.8 million for
the year ended December 31, 2021.

Premiums ceded to SPCs represent alternative market business that is ceded under
100% quota share agreements to the SPCs in our Segregated Portfolio Cell
Reinsurance segment. Premiums ceded to unaffiliated captive insurer represent
alternative market business for one program that is ceded under a 100% quota
share reinsurance agreement. Alternative market premiums written decreased in
2021, which resulted in lower premium ceded to SPCs. See further discussion on
alternative market gross premiums written in our Segment Operating Results -
Segregated Portfolio Cell Reinsurance section under the heading "Gross Premiums
Written" that follows.

Under our external reinsurance agreement for traditional business, we retain the
first $0.5 million in risk insured by us and cede losses in excess of this
amount on each loss occurrence under our primary external reinsurance treaty,
subject to an AAD equal to 3.5% of ceded earned premium for the treaty year
effective May 1, 2021. Per our reinsurance agreements, we cede premiums related
to our traditional business on an earned premium basis. The decrease in premiums
ceded to external reinsurers during the year ended December 31, 2021 primarily
reflected lower earned premium, partially offset by an increase in reinsurance
rates effective May 1, 2021.

Changes in the return premium estimate reflected adjustments to our estimate of
expected future recovery of ceded premium based on the underlying loss
experience of our reinsurance contracts that include a provision for return
premium. We increased our estimate of return premium by $0.6 million for the
year ended December 31, 2021 as compared to a nominal amount in 2020. The change
in estimated return premium for the year ended December 31, 2021 primarily
reflected favorable prior year loss development on previously reported reinsured
claims.

Ceded Premiums Ratio

Ceded premiums ratio was as follows:

The above table reflects traditional ceded premiums earned as a percent of
traditional gross premiums earned. As discussed above, we cede premiums in our
traditional business to external reinsurers on an earned premium basis. The
increase in the ceded premiums ratio in 2021 as compared to 2020 primarily
reflected the increase in reinsurance rates.

Net Premiums Earned


Net premiums earned consist of gross premiums earned less the portion of earned
premiums that we cede to SPCs in our Segregated Portfolio Cell Reinsurance
segment, external reinsurers (including changes related to the return premium
and revenue share estimates) and the unaffiliated captive insurer. Because
premiums are earned pro rata over the entire policy period, fluctuations in
premiums earned tend to lag those of premiums written. Our workers' compensation
policies are twelve month term policies, and premiums are earned on a pro rata
basis over the policy period. Net premiums earned also include premium
adjustments related to the audit of our insureds' payrolls, changes in our EBUB
estimate and premium adjustments related to retrospectively-rated policies.
Payroll audits are conducted subsequent to the end of the policy period and any
related premium adjustments processed are recorded as fully earned in the
current period. In addition, we record an estimate for EBUB and evaluate the
estimate on a quarterly basis.

Net premiums earned were as follows:


                                                       Year Ended December 

31

               ($ in thousands)           2021           2020               

Change

Gross premiums earned $ 243,665 $ 255,484 $ (11,819) (4.6 %)

Less: Ceded premiums earned 79,065 83,712 (4,647) (5.6 %)

         Net premiums earned           $ 164,600      $ 171,772      $  

(7,172) (4.2 %)



The decrease in net premiums earned during the year ended December 31, 2021 as
compared to 2020 primarily reflected the pro rata effect of a reduction in net
premiums written during the preceding twelve months and the impact of audit
premium returned to policyholders. The decrease in net premiums earned during
the year ended December 31, 2021 was partially offset by a decrease in negative
premium adjustments under retrospectively-rated policies and a decrease in ceded
earned premium, which reflected the increased revenue share and return premium
estimates.

Losses and Loss Adjustment Expenses


We estimate our current accident year loss and loss adjustment expenses by
developing actual reported losses using historical loss development factors,
adjusted to reflect current and expected trends based on various internal
analyses and supplemental information. The following table summarizes calendar
year net loss ratios by separating losses between the current accident year and
all prior accident years. Calendar year and current accident year net loss
ratios by component were as follows:

                                                                           

Year Ended December 31

                                                           2021                    2020                    Change
Calendar year net loss ratio                                  69.7  %                 64.9  %                 4.8   pts

Less impact of prior accident years on the net loss
ratio

                                                         (4.3  %)                (4.1  %)               (0.2   pts)
Current accident year net loss ratio                          74.0  %                 69.0  %                 5.0   pts


The current accident year loss ratio increased in 2021 as compared to 2020,
reflecting workers returning to full employment in 2021 after the lifting of
pandemic-related restrictions and the labor shortage. We experienced an increase
in reported claim activity in 2021, including an increase in severity-related
claim activity. The increase in reported claim activity is attributable to
workers being out of "work shape" as they returned to employment in 2021 as well
as the lack of training, alternative work arrangements and employee fatigue due
to the labor shortage. The current accident year loss ratio in 2021 was also
impacted by the continuation of intense price competition and the resulting
renewal rate decreases as well as the reduction in net premiums earned related
to negative audit premium, as previously discussed.

Calendar year incurred losses (excluding IBNR) in excess of our per occurrence
reinsurance retention, before consideration of the AAD (see previous discussion
under the heading "Ceded Premiums Written"), increased $11.3 million in 2021 as
compared to 2020. Current accident year ceded incurred losses totaled $6.9
million in 2021 as compared to $2.8 million in 2020. We retained calendar year
incurred losses in excess of our per occurrence retention totaling $6.6 million
for the year ended December 31, 2021 which reflected losses within the AAD.

We recognized net favorable prior year development related to our previously
established reserve of $7.1 million for the year ended December 31, 2021 as
compared to $7.0 million for 2020. The net favorable prior year reserve
development for the years ended December 31, 2021 and 2020 reflected overall
favorable trends in claim closing patterns. Net favorable development for the
year ended December 31, 2021 primarily related to accident years 2012 through
2017. Net favorable development for the year ended December 31, 2020 primarily
related to accident years 2014 through 2017.

Underwriting, Policy Acquisition and Operating Expenses


Underwriting, policy acquisition and operating expenses include the amortization
of commissions, premium taxes and underwriting salaries, which are capitalized
and deferred over the related workers' compensation policy period, net of ceding
commissions earned. The capitalization of underwriting salaries can vary as they
are subject to the success rate of our contract acquisition efforts. These
expenses also include a management fee charged by our Corporate segment, which
represents intercompany charges pursuant to a management agreement, and the
amortization of intangible assets, primarily related to the acquisition of
Eastern by ProAssurance. The management fee is based on the extent to which
services are provided to the subsidiary and the amount of premium written by the
subsidiary.

Our Workers' Compensation Insurance segment underwriting, policy acquisition and
operating expenses were comprised as follows:


                                                               Year Ended

   Total                                        $ 52,418      $ 56,449      $ (4,031)       (7.1  %)

The decrease in DPAC amortization for the year ended December 31, 2021 as
compared to 2020 primarily reflected the decrease in net premiums earned.


The decrease in other underwriting and operating expenses for the year ended
December 31, 2021 as compared to 2020 primarily reflected a decrease in
compensation-related costs driven by a reduction in headcount as a result of the
third quarter of 2020 restructuring and a reduction in our allowance for
expected credit losses, partially offset by an increase in expenses related to
our policy administration and claim system implementation project. Additionally,
the decrease in other underwriting and operating expenses in 2021 as compared to
2020 reflected the prior year effect of one-time costs of $0.9 million primarily
comprised of employee severance costs associated with the 2020 restructuring.

As previously discussed, alternative market premiums written by our Workers'
Compensation Insurance segment unit are 100% ceded, less a ceding commission, to
either the SPCs in our Segregated Portfolio Cell Reinsurance segment or, to a
limited extent, an unaffiliated captive insurer. The ceding commission charged
to the SPCs consists of an amount for fronting fees, cell rental fees,
commissions, premium taxes and risk management fees. The fronting fees,
commissions, premium taxes and risk management fees are recorded as an offset to
underwriting, policy acquisition and operating expenses. Cell rental fees are
recorded as a component of other income and claims administration fees are
recorded as ceded ULAE. The decrease in SPC ceding commissions earned for the
year ended December 31, 2021 as compared to 2020, primarily reflected the
decrease in alternative market ceded earned premium.

Underwriting Expense Ratio (the Expense Ratio)

The underwriting expense ratio included the impact of the following:

Excluding the items noted in the table above, the expense ratio decreased for
the year ended December 31, 2021, primarily reflecting the reduction in
compensation-related costs and the allowance for credit losses noted above,
partially offset by the decrease in net premiums earned.

Segment Results - Segregated Portfolio Cell Reinsurance

The Segregated Portfolio Cell Reinsurance segment includes the results
(underwriting profit or loss, plus investment results, net of U.S. federal
income taxes) of SPCs at Inova Re and Eastern Re, our Cayman Islands SPC
operations, as discussed in Note 19 of the Notes to Consolidated Financial
Statements. SPCs are segregated pools of assets and liabilities that provide an
insurance facility for a defined set of risks. Assets of each SPC are solely for
the benefit of that individual cell and each SPC is solely responsible for the
liabilities of that individual cell. Assets of one SPC are statutorily protected
from the creditors of the others. Each SPC is owned, fully or in part, by an
individual company, agency, group or association and the results of the SPCs are
attributable to the participants of that cell. We participate to a varying
degree in the results of selected SPCs and, for the SPCs in which we
participate, our participation interest ranges from a low of 20% to a high of
85%. SPC results attributable to external cell participants are reported as an
SPC dividend (expense) income in our Segregated Portfolio Cell Reinsurance
segment. In addition, our Segregated Portfolio Cell Reinsurance segment includes
the investment results of the SPCs as the investments are solely for the benefit
of the cell participants and investment results attributable to external cell
participants are reflected in the SPC dividend (expense) income. As of
December 31, 2021, there were 27 (4 inactive) SPCs. The SPCs assume workers'
compensation insurance, healthcare professional liability insurance or a
combination of the two from our Workers' Compensation Insurance and Specialty
P&C segments. As of December 31, 2021, there were two SPCs that assumed both
workers' compensation insurance and healthcare professional liability insurance
and one SPC that assumed only healthcare professional liability insurance.

Segment results reflects our share of the underwriting and investment results of
the SPCs in which we participate, and included the following:

Premiums Written


Premiums in our Segregated Portfolio Cell Reinsurance segment are assumed from
either our Workers' Compensation Insurance or Specialty P&C segments. Premium
volume is driven by five primary factors: (1) the amount of new business
written, (2) retention of the existing book of business, (3) premium rates
charged on the renewal book of business and, for workers' compensation business,
(4) changes in payroll exposure and (5) audit premium.

Gross, ceded and net premiums written were as follows:

                                                        Year Ended December 31
                 ($ in thousands)           2021          2020                Change
          Gross premiums written         $ 71,850      $ 72,843      $   (993)       (1.4  %)
          Less: Ceded premiums written      8,808         8,684           124         1.4  %
          Net premiums written           $ 63,042      $ 64,159      $ (1,117)       (1.7  %)


Gross Premiums Written

Gross premiums written reflected reinsurance premiums assumed by component as
follows:

                                                          Year Ended December 31
                ($ in thousands)              2021          2020                Change
       Workers' compensation               $ 64,639      $ 66,725      $ 

(2,086) (3.1 %)

Healthcare professional liability 7,211 6,118 1,093 17.9 %


       Gross Premiums Written              $ 71,850      $ 72,843      $   

(993) (1.4 %)



Gross premiums written for the years ended December 31, 2021 and 2020 were
primarily comprised of workers' compensation coverages assumed from our Workers'
Compensation Insurance segment. Workers' compensation gross premiums written
decreased during the year ended December 31, 2021 as compared to 2020, which
primarily reflected the competitive workers' compensation market conditions and
the resulting renewal rate decreases of 4%, partially offset by an improvement
in renewal retention. The renewal retention rate during 2020 includes the impact
of a reduction in premium funding for a large workers' compensation program. We
do not participate in this program; therefore, the reduction in premium funding
had no effect on the segment results for the year ended December 31, 2021. The
increase in healthcare professional liability gross premiums written in 2021 as
compared to 2020 primarily reflected higher renewal pricing and exposure
increases in two programs. We retained 22 of the 23 workers' compensation
alternative market programs up for renewal for the year ended December 31, 2021.
During the fourth quarter, we placed one program into run-off due to continued
unfavorable underwriting results. The program had gross written premium of $1.8
million for the year ended December 31, 2021. We retained 100% of the 3
healthcare professional liability programs up for renewal during 2021.

New business, audit premium, retention and renewal price changes for the assumed
workers' compensation premium is shown in the table below:

Year Ended December 31

(1) We calculate our workers' compensation retention rate as annualized expiring renewed premium
divided by all annualized expiring premium subject to renewal. Our retention rate can be impacted by
various factors, including price or other competitive issues, insureds being acquired, or a decision
not to renew based on our underwriting evaluation.
(2) The pricing of our business includes an assessment of the underlying policy exposure and market
conditions. We continue to base our pricing on expected losses, as indicated by our historical loss
data.

Ceded Premiums Written

Ceded premiums written were as follows:

                                                     Year Ended December 31
                    ($ in thousands)        2021          2020             Change
                Ceded premiums written   $   8,808      $ 8,684      $ 124       1.4  %


For the workers' compensation business, each SPC has in place its own external
reinsurance arrangements. The healthcare professional liability business is
assumed net of reinsurance from our Specialty P&C segment; therefore, there are
no ceded premiums related to the healthcare professional liability business
reflected in the table above. The risk retention for each loss occurrence for
the workers' compensation business ranges from $0.3 million to $0.4 million
based on the program, with limits up to $119.7 million. In addition, each
program has aggregate reinsurance coverage between $1.1 million and $2.1 million
on a program year basis. Per the SPC external reinsurance agreements, premiums
are ceded on a written premium basis. The change in ceded premiums written in
2021 as compared to 2020 primarily reflected the impact of rate increases under
the external reinsurance contract, partially offset by the decrease in workers'
compensation gross premiums written. External reinsurance rates vary based on
the alternative market program.

Ceded Premiums Ratio

Ceded premiums ratio was as follows:

                                                 Year Ended December 31
                                             2021              2020        Change
              Ceded premiums ratio                13.6  %     13.0  %     0.6   pts


The above table reflects ceded premiums as a percent of gross premiums written
for the workers' compensation business only; healthcare professional liability
business is assumed net of reinsurance, as discussed above. The ceded premiums
ratio reflects the weighted average reinsurance rates of all SPC programs. The
increase in the ceded premiums ratio for the year ended December 31, 2021
reflects an increase in reinsurance rates.

Net Premiums Earned


Net premiums earned consist of gross premiums earned less the portion of earned
premiums that the SPCs cede to external reinsurers. Because premiums are
generally earned pro rata over the entire policy period, fluctuations in
premiums earned tend to lag those of premiums written. Policies ceded to the
SPCs are twelve month term policies and premiums are earned on a pro rata basis
over the policy period. Net premiums earned also include premium adjustments
related to the audit of workers' compensation insureds' payrolls. Payroll audits
are conducted subsequent to the end of the policy period and any related
adjustments processed are recorded as fully earned in the current period.

Gross, ceded and net premiums earned were as follows:

                                                       Year Ended December 31
                ($ in thousands)           2021          2020                Change
          Gross premiums earned         $ 72,359      $ 75,112      $ (2,753)       (3.7  %)
          Less: Ceded premiums earned      8,671         8,760           (89)       (1.0  %)
          Net premiums earned           $ 63,688      $ 66,352      $ (2,664)       (4.0  %)

The decrease in net premiums earned during the year ended December 31, 2021
primarily reflected the pro rata effect of a reduction in net premiums written
during the preceding twelve months.

Net Investment Income and Net Investment Gains (Losses)


Net investment income for the years ended December 31, 2021 and 2020 was
primarily attributable to interest earned on available-for-sale fixed maturity
investments, which primarily include investment-grade corporate debt securities.
We recognized $4.1 million and $3.1 million of net investment gains for the
years ended December 31, 2021 and 2020, respectively, which primarily reflected
an increase in the fair value of our equity portfolio.

                                      101

Table of Contents

Losses and Loss Adjustment Expenses


The following table summarizes the calendar year net loss ratios by separating
losses between the current accident year and all prior accident years. The
current accident year net loss ratio reflects the aggregate loss ratio for all
programs. Loss reserves are estimated for each program on a quarterly basis. Due
to the size of some of the programs, quarterly loss results can create
volatility in the current accident year net loss ratio from period to period.

Calendar year and current accident year net loss ratios for the years ended
December 31, 2021 and 2020 were as follows:

                                                             Year Ended December 31
                                                   2021                       2020             Change

Calendar year net loss ratio                           51.1  %                    44.6  %                                   6.5   pts
Less impact of prior accident years on the
net loss ratio                                        (16.0  %)                  (25.0  %)                                  9.0   pts
Current accident year net loss ratio                   67.1  %                    69.6  %                                  (2.5   pts)


The current accident year net loss ratio decreased in 2021 as compared to 2020,
primarily reflecting favorable trends in the prior accident year claim results
and their impact on our analysis of the current accident year loss estimate. The
decrease was partially offset by the continuation of intense price competition
and the resulting renewal rate decreases in the workers' compensation business
as well as the impact of higher claim activity related to workers returning to
full employment in 2021 after the lifting of pandemic-related restrictions and
the labor shortage.

Calendar year incurred losses (excluding IBNR) ceded to our external reinsurers
increased $5.2 million for the year ended December 31, 2021 as compared to 2020.
Current accident year ceded incurred losses (excluding IBNR) increased $2.3
million for the year ended December 31, 2021 as compared to 2020.

We recognized net favorable prior year reserve development of $10.2 million and
$16.5 million for the years ended December 31, 2021 and 2020, respectively.


Net favorable prior year reserve development in the workers' compensation
business totaled $7.6 million in 2021 as compared to $12.1 million in 2020. The
2021 net favorable prior year reserve development related primarily to accident
year 2015 and accident years 2018 through 2020. The 2020 net favorable
development related primarily to accident years 2018 and 2019.

Net favorable prior year reserve development in the healthcare professional
liability business totaled $2.5 million in 2021 as compared to $4.4 million in
2020. The 2021 net favorable prior year reserve development related primarily to
accident years 2018 through 2020, while the 2020 net favorable prior year
reserve development related primarily to accident years 2017 through 2019.

Underwriting, Policy Acquisition and Operating Expenses

Our Segregated Portfolio Cell Reinsurance segment underwriting, policy
acquisition and operating expenses were comprised as follows:


                                                               Year Ended

DPAC amortization primarily represents ceding commissions, which vary by program
and are paid to our Workers' Compensation Insurance and Specialty P&C segments
for premiums assumed. Ceding commissions include an amount for fronting fees,
commissions, premium taxes and risk management fees, which are reported as an
offset to underwriting, policy acquisition and operating expenses within our
Workers' Compensation Insurance and Specialty P&C segments. In addition, ceding
commissions paid to our Workers' Compensation Insurance segment include cell
rental fees which are recorded as other income and claims administration fees
which are recorded as ceded ULAE within our Workers' Compensation Insurance
segment.

Other underwriting and operating expenses primarily include bank fees,
professional fees and changes in the allowance for expected credit losses. The
increase in other underwriting and operating expenses for the year ended
December 31, 2021 as


                                      102

--------------------------------------------------------------------------------

Table of Contents


compared to 2020 primarily reflected the change in our allowance for expected
credit losses related to one program in which we do not participate, partially
offset by a decrease in professional fees.

The increase in policyholder dividend expense for the year ended December 31,
2021 as compared to 2020, related primarily to one SPC program, in which we do
not participate.

Underwriting Expense Ratio (the Expense Ratio)

The underwriting expense ratio included the impact of the following:

Year Ended December 31

                                                             2021                    2020                   Change
Underwriting expense ratio, as reported                         34.0  %                 31.2  %                2.8   pts
Less: impact of audit premium on expense ratio                  (0.5  %)                 0.1  %               (0.6   pts)

Underwriting expense ratio, excluding the effect of
audit premium

                                                   34.5  %                 31.1  %                3.4   pts


Excluding the effect of audit premium, the underwriting expense ratio increased
for the year ended December 31, 2021. The increase primarily reflected the
change in the allowance for expected credit losses and policyholder dividend
expense, as discussed above, as well as the decrease in net premiums earned.

SPC U.S. Federal Income Tax Expense


The SPCs at Inova Re have made a 953(d) election under the U.S. Internal Revenue
Code and are subject to U.S. federal income tax. U.S. federal income taxes
incurred totaled $1.9 million and $1.7 million for the years ended December 31,
2021 and 2020, respectively. U.S. federal income taxes are included in the total
SPC net results and are paid by the individual SPCs.

Segment Results - Lloyd's Syndicates


Our Lloyd's Syndicates segment includes the results from our participation in
certain Syndicates at Lloyd's of London. In addition to our participation in
Syndicate results, we have investments in and other obligations to our Lloyd's
Syndicates consisting of a Syndicate Credit Agreement and FAL requirements. For
the 2021 underwriting year, our FAL was comprised of investment securities and
cash and cash equivalents deposited with Lloyd's which at December 31, 2021 had
a fair value of approximately $37.8 million, as discussed in Note 4 of the Notes
to Consolidated Financial Statements. During the second and fourth quarters of
2021, we received a return of approximately $24.5 million and $8.0 million,
respectively, of cash from our FAL balances given the reduction in our
participation in the results of Syndicate 1729, to 5% from 29%, and Syndicate
6131, to 50% from 100%, for the 2021 underwriting year. Further, during the
fourth quarter of 2021, we received a return of approximately $26.6 million of
cash from our FAL balances given Syndicate 6131 ceased underwriting on a quota
share basis with Syndicate 1729 as Syndicate 6131's business is retained within
Syndicate 1729 beginning with the 2022 underwriting year.

We normally report results from our involvement in Lloyd's Syndicates on a
quarter lag, except when information is available that is material to the
current period. Furthermore, the investment results associated with our FAL
investments and certain U.S. paid administrative expenses are reported
concurrently as that information is available on an earlier time frame.


Lloyd's Syndicate 1729. We provide capital to Syndicate 1729, which covers a
range of property and casualty insurance and reinsurance lines in both the U.S.
and international markets. The remaining capital for Syndicate 1729 is provided
by unrelated third parties, including private names and other corporate members.
As previously discussed, we decreased our participation in the results of
Syndicate 1729 for the 2021 underwriting year to 5% to support and grow our core
insurance operations. Due to the quarter lag, this reduced participation was not
reflected in our results until the second quarter of 2021. Syndicate 1729 had a
maximum underwriting capacity of £185 million (approximately $250 million based
on December 31, 2021 exchange rates) for the 2021 underwriting year, of which £9
million (approximately $13 million based on December 31, 2021 exchange rates)
was our allocated underwriting capacity. For the 2022 underwriting year, our
participation in the results of Syndicate 1729 remains unchanged at 5%.
Syndicate 1729's maximum underwriting capacity for the 2022 underwriting year is
£210 million (approximately $284 million at December 31, 2021), of which £11
million (approximately $15 million at December 31, 2021) is our allocated
underwriting capacity.

Lloyd's Syndicate 6131. Prior to January 1, 2022, we provided capital to an SPA,
Syndicate 6131, which focused on contingency and specialty property business.
Effective July 1, 2020, Syndicate 6131 entered into a six-month quota share
reinsurance agreement with an unaffiliated insurer. Under this agreement,
Syndicate 6131 ceded essentially half of the premium assumed from Syndicate 1729
to the unaffiliated insurer; the agreement was non-renewed on January 1, 2021
and we decreased our participation in the results of Syndicate 6131 to 50% from
100% for the 2021 underwriting year, as previously discussed. Due to the quarter
lag, this reduced participation was not reflected in our results until the
second quarter of 2021. Syndicate 6131 had a maximum underwriting capacity for
the 2021 underwriting year of £20 million (approximately $27 million based on
December 31, 2021 exchange rates), of which £10 million (approximately $14
million based on December 31, 2021 exchange rates) was our allocated
underwriting capacity. Effective January 1, 2022, Syndicate 6131 ceased
underwriting on a quota share basis with Syndicate 1729 as Syndicate 6131's
business is retained within Syndicate 1729 beginning with the 2022 underwriting
year, as previously discussed. Premium from our participation in the results of
Syndicate 6131 from open underwriting years prior to 2022 will continue to earn
out pro rata over the entire policy period of the underlying business.

Premiums Written

Changes in premium volume within our Lloyd's Syndicates segment are driven by
five primary factors: (1) changes in our participation in the Syndicates, (2)
the amount of new business and the channels in which the business is written,
(3) the retention of existing business, (4) the premium charged for business
that is renewed, which is affected by rates charged and by the amount and type
of coverage an insured chooses to purchase and (5) the timing of premium written
through multi-period policies.

Gross, ceded and net premiums written were as follows:


                                          Year Ended December 31
       ($ in thousands)           2021       2020            Change

Gross premiums written $ 37,969 $ 84,718 $ (46,749) (55.2 %)
Less: Ceded premiums written 6,302 17,066 (10,764) (63.1 %)
Net premiums written

           $ 31,667   $ 67,652   $ (35,985)   (53.2  %)


Gross Premiums Written

Gross premiums written in 2021 consisted of specialty property coverages (31% of
total gross premiums written), property insurance coverages (27%), casualty
coverages (26%), contingency coverages (9%), catastrophe reinsurance coverages
(5%) and property reinsurance coverages (2%). The decrease in gross premiums
written in 2021 as compared to 2020 was primarily driven by our decreased
participation in the results of Syndicates 1729 and 6131, partially offset by
volume increases on renewal business and renewal pricing increases, primarily on
property insurance and casualty coverages and new business written, primarily on
specialty property and property insurance coverages.

Ceded Premiums Written


Syndicate 1729 utilizes reinsurance to provide the capacity to write larger
limits of liability on individual risks, to provide protection against
catastrophic loss and to provide protection against losses in excess of policy
limits. As previously discussed, for the second half of 2020 Syndicate 6131
utilized external quota share reinsurance to manage the net loss exposure on the
specialty property and contingency coverages it assumed from Syndicate 1729 by
ceding essentially half of the premium assumed to an unaffiliated insurer; this
agreement was non-renewed on January 1, 2021. Due to the quarter lag, the effect
of this six-month reinsurance arrangement began to be reflected in our results
in the fourth quarter of 2020. Ceded premiums written decreased for the year
ended December 31, 2021 as compared to 2020 primarily driven by our decreased
participation in the results of Syndicates 1729 and 6131 and, to a lesser
extent, the impact of an increase in estimated reinsurance reinstatement
premiums of $1.2 million during the fourth quarter of 2020 triggered by certain
property and catastrophe related losses exceeding specified levels in the
reinsurance agreement.

Net Premiums Earned


Net premiums earned consist of gross premiums earned less the portion of earned
premiums that the Syndicates cede to reinsurers for their assumption of a
portion of losses. Premiums written through open-market channels are generally
earned pro rata over the entire policy period, which is predominantly twelve
months, whereas premiums written through delegated underwriting authority
arrangements are generally earned over the policy period plus twelve months.
Therefore, net premiums earned is affected by shifts in the mix of policies
written between the open-market and delegated underwriting authority
arrangements. Additionally, net premiums earned consists of a mix of policies
earned from different open underwriting years. As previously discussed, we
participate to a varying degree in each open underwriting year which may cause
fluctuations in premiums earned. Furthermore, fluctuations in premiums earned
tend to lag those of premiums written. Premiums for certain policies and assumed
reinsurance contracts are reported subsequent to the coverage period and/or may
be subject to adjustment based on loss experience. These premium adjustments are
earned when reported, which can result in further fluctuation in earned premium.

Gross, ceded and net premiums earned were as follows:

                                                      Year Ended December 31
                ($ in thousands)           2021          2020               Change
          Gross premiums earned         $ 60,590      $ 98,990      $ (38,400)   (38.8  %)
          Less: Ceded premiums earned     12,218        21,764         (9,546)   (43.9  %)
          Net premiums earned           $ 48,372      $ 77,226      $ (28,854)   (37.4  %)


The decrease in net premiums earned for the year ended December 31, 2021 as
compared to 2020 was driven by our decreased participation in Syndicates 1729
and 6131, partially offset by the effect of the aforementioned reinstatement
premiums earned of $1.2 million during the fourth quarter of 2020.

Net Losses and Loss Adjustment Expenses


Losses for the year were primarily recorded using the loss assumptions by risk
category incorporated into the business plans submitted to Lloyd's for Syndicate
1729 and Syndicate 6131 with consideration given to loss experience incurred to
date. The assumptions used in each business plan were consistent with loss
results reflected in Lloyd's historical data for similar risks. The loss ratios
may fluctuate due to the mix of earned premium and the timing of earned premium
adjustments (see discussion in this section under the heading "Net Premiums
Earned"). Premium and exposure for some of Syndicate 1729's insurance policies
and reinsurance contracts are initially estimated and subsequently adjusted over
an extended period of time as underlying premium reports are received from
cedents and insureds. When reports are received, the premium, exposure and
corresponding loss estimates are revised accordingly. Changes in loss estimates
due to premium or exposure fluctuations are incurred in the accident year in
which the premium is earned.

The following table summarizes calendar year net loss ratios by separating
losses between the current accident year and all prior accident years. Net loss
ratios for the period were as follows:

Year Ended December 31

                                                        2021                  2020                    Change
Calendar year net loss ratio                              61.6  %                65.0  %                 (3.4   pts)
Less impact of prior accident years on the net
loss ratio                                                 9.7  %                 0.8  %                  8.9   pts
Current accident year net loss ratio                      51.9  %                64.2  %                (12.3   pts)


For the year ended December 31, 2021, the current accident year net loss ratio
decreased 12.3 percentage points as compared to 2020. The decrease in the
current accident year net loss ratio was primarily driven by higher reinsurance
recoveries as a proportion of gross losses as compared to the prior year period,
partially offset by certain catastrophe related losses.

We recognized $4.7 million and $0.6 million of unfavorable prior year
development for the years ended December 31, 2021 and 2020, respectively. The
unfavorable prior year development for the year ended December 31, 2021 was
driven by higher than expected losses and development on certain large claims,
primarily catastrophe related losses.

We have exposures to potential COVID-19 claims through our participation in
Syndicates 1729 and 6131. During 2021, we recognized losses related to COVID-19
of approximately $1.6 million, net of reinsurance, as compared to $3.6 million
during 2020, primarily in Syndicate 6131's contingency and Syndicate 1729's
casualty books of business. See previous discussion in Part I, Item 1 under the
heading "Insurance Regulatory Matters- COVID-19."

Underwriting, Policy Acquisition and Operating Expenses

Underwriting, policy acquisition and operating expenses decreased by $12.2
million for the year ended December 31, 2021 as compared to 2020 and reflected
our decreased participation in Syndicate 1729 and Syndicate 6131.


For the year ended December 31, 2021, the underwriting expense ratio decreased
by 1.9 percentage points as compared to 2020 which primarily reflected the
impact of our reduced participation in Syndicate 1729 and Syndicate 6131.
Operating expenses incurred during 2021 primarily were related to the 2021
underwriting year for which our participation is 5% and 50% in Syndicate 1729
and Syndicate 6131, respectively, whereas the net premiums earned during the
same period also includes premium from other open underwriting years in which we
participate at a higher degree.

Investments


Syndicate 1729's fixed maturity portfolio includes certain debt securities
classified as trading securities. Investment results associated with these fixed
maturity trading securities are reported on the same quarter lag. The decrease
in net investment income in 2021 as compared to 2020 was primarily attributable
to lower average investment balances and lower yields, primarily from
investment-grade corporate debt securities. The lower average investment balance
in 2021 was driven by the return of approximately $32.3 million of cash and cash
equivalents from our FAL balances during the third quarter of 2020 given the
reduction in our participation in the results of Syndicate 1729 to 29% from 61%
for the 2020 underwriting year. In addition, we received a return of
approximately $24.5 million and $8.0 million of cash from our FAL balances
during the second and fourth quarters of 2021, respectively, given the
additional reduction in our participation in the results of Syndicate 1729 and
Syndicate 6131 for the 2021 underwriting year, as previously discussed. Further,
during the fourth quarter of 2021, we received a return of approximately
$26.6 million of cash from our FAL balances given the decision to incorporate
Syndicate 6131's business into Syndicate 1729 for the 2022 underwriting year, as
previously discussed. Our lower FAL balances will continue to impact the
segment's net investment income in future periods.

Taxes

The results of this segment are subject to U.K. income tax law.

Segment Results - Corporate


Our Corporate segment includes our investment operations, including the
investment operations of NORCAL since the date of acquisition and excludes those
reported in our Segregated Portfolio Cell Reinsurance and Lloyd's Syndicates
segments as discussed in Note 18 of the Notes to Consolidated Financial
Statements. In addition, this segment includes corporate expenses, interest
expense, U.S. income taxes and non-premium revenues generated outside of our
insurance entities. Segment results for the year ended December 31, 2021 exclude
transaction-related costs and the associated income tax benefit related to the
NORCAL acquisition as we do not consider these items in assessing the financial
performance of the segment (Note 2 of the Notes to Consolidated Financial

Net Investment Income, Equity in Earnings (Loss) of Unconsolidated Subsidiaries,
Net Investment Gains (Losses)

Net Investment Income


Net investment income is primarily derived from the income earned by our fixed
maturity securities and also includes dividend income from equity securities,
income from our short-term and cash equivalent investments, earnings from other
investments and increases in the cash surrender value of BOLI contracts, net of
investment fees and expenses. Net investment income in 2021 also includes income
earned, net of investment fees and expenses, since the date of acquisition from
investments acquired from NORCAL .

Net investment income by investment category was as follows:

Fixed Maturities

Income from our fixed maturities increased in 2021 as compared to 2020 driven by
higher average investment balances primarily attributable to the addition of
fixed maturity securities valued at $1.1 billion to our portfolio on May 5, 2021
as a result of the NORCAL acquisition (see Note 2 of the Notes to Consolidated
Financial Statements for additional information). The increase in income from
our fixed maturities in 2021 was partially offset by lower yields from our
corporate debt securities and the impact of capital planning in anticipation of
closing the NORCAL acquisition. As a result of the NORCAL acquisition, average
investment balances were approximately 51% higher for 2021 as compared to 2020;
excluding the impact of the acquisition, average investment balances were
approximately 10% higher.

Average yields for our fixed maturity portfolio were as follows:

                                                     Year Ended December 31
                                                   2021                   2020
          Average income yield                     2.3%                   3.1%
          Average tax equivalent income yield      2.3%                   3.1%

Yields on fixed maturity securities decreased in 2021 as compared to 2020. The
decrease in 2021 was primarily driven by the application of GAAP purchase
accounting rules whereby all NORCAL fixed maturity securities acquired were
valued at fair value on the date of acquisition resulting in lower average
yields on those securities as compared to the average yields on our other
securities.

Equities


Income from our equity portfolio decreased in 2021 as compared to 2020 due to a
decrease in our allocation to this asset category during the first half of 2021
and, to a lesser extent, the reallocation in our mix of securities within this
asset category.

Short-term Investments and Other Investments


Short-term investments, which have a maturity at purchase of one year or less
are carried at fair value, which approximates their cost basis, and are
primarily composed of investments in U.S. treasury obligations, commercial paper
and money market funds. Income from our short-term and other investments
decreased during 2021 primarily attributable to lower yields given the actions
taken by the Federal Reserve to aggressively reduce interest rates in response
to COVID-19, partially offset by income contributed by investments acquired from
NORCAL.

BOLI

We hold BOLI policies that are carried at the current cash surrender value of
the policies, which includes the BOLI policies acquired from NORCAL. All insured
individuals were members of ProAssurance or NORCAL management at the time the
policies were acquired. Income from our BOLI policies increased in 2021 as
compared to 2020 primarily attributable to the addition of BOLI policies valued
at $10 million to our portfolio on May 5, 2021 as a result of the NORCAL
acquisition.

Investment Fees and Expenses


Investment fees and expenses increased in 2021 as compared to 2020 driven by
additional costs associated with our investments acquired from NORCAL since the
date of acquisition.

Equity in Earnings (Loss) of Unconsolidated Subsidiaries

Equity in earnings (loss) of unconsolidated subsidiaries was comprised as

We hold interests in certain LPs/LLCs that generate earnings from trading
portfolios, secured debt, debt securities, multi-strategy funds and private
equity investments. The performance of the LPs/LLCs is affected by the
volatility of equity and credit markets. For our investments in LPs/LLCs, we
record our allocable portion of the partnership operating income or loss as the
results of the LPs/LLCs become available, typically following the end of a
reporting period. The increase in our investment results from our portfolio of
investments in LPs/LLCs for 2021 as compared to 2020 was due to higher earnings
from several LPs/LLCs and the prior year effect of the volatility in global
financial markets related to COVID-19. Our investment results from our portfolio
of investments in LPs/LLCs in 2021 included additional earnings of approximately
$1.4 million from acquired interests in four LPs as a result of the NORCAL
acquisition; given the results of our investments in LPs/LLCs are often reported
to us on a one quarter lag, the earnings from these investments were not
reflected in our results until the third quarter of 2021.

Our tax credit partnership investments are designed to generate returns in the
form of tax credits and tax-deductible project operating losses and are
comprised of qualified affordable housing project tax credit partnerships and a
historic tax credit partnership. We account for our tax credit partnership
investments under the equity method and record our allocable portion of the
operating losses of the underlying properties based on estimates provided by the
partnerships. For our qualified affordable housing project tax credit
partnerships, we adjust our estimates of our allocable portion of operating
losses

periodically as actual operating results of the underlying properties become
available. The primary benefits of tax credits and tax-deductible operating
losses from the historic tax credit partnerships are earned in a short period
with potential for additional cash flows extending over several years. The
results from our tax credit partnership investments for the year ended
December 31, 2021 reflected lower partnership operating losses as compared to
2020. In addition, based on results received, we increased our estimate of
operating losses by $1.9 million and $4.3 million for the years ended
December 31, 2021 and 2020, respectively.

The tax benefits received from our tax credit partnerships, which are not
reflected in our investment results, reduced our tax expense in 2021 and 2020 as
follows:

$ 4.2



The tax credits generated from our tax credit partnership investments of $13.2
million for 2021 were deferred for use in future periods due to the utilization
of NOLs available to us following our acquisition of NORCAL. For the year ended
December 31, 2020, due to our consolidated pre-tax loss, the tax credits
generated from our tax credit partnership investments of $17.9 million were
deferred to be utilized in future periods. For the year ended December 31, 2021,
we utilized approximately $2.0 million of tax credits carried forward from 2019
and, as of December 31, 2021, we had approximately $46.7 million of available
tax credit carryforwards generated from our investments in tax credit
partnerships which we expect to utilize in future years. See further discussion
in Note 7 of the Notes to Consolidated Financial Statements.

Tax credits provided by the underlying projects of our historic tax credit
partnership are typically available in the tax year in which the project is put
into active service, whereas the tax credits provided by qualified affordable
housing project tax credit partnerships are provided over approximately a ten
year period.

Non-GAAP Financial Measure - Tax Equivalent Investment Result


We believe that to fully understand our investment returns it is important to
consider the current tax benefits associated with certain investments as the tax
benefit received represents a portion of the return provided by our tax-exempt
bonds, BOLI, common and preferred stocks, and tax credit partnership investments
(collectively, our tax-preferred investments). We impute a pro forma
tax-equivalent result by estimating the amount of fully-taxable income needed to
achieve the same after-tax result as is currently provided by our tax-preferred
investments. We believe this better reflects the economics behind our decision
to invest in certain asset classes that are either taxed at lower rates and/or
result in reductions to our current federal income tax expense. Our pro forma
tax-equivalent investment result is shown in the table that follows as well as a
reconciliation of our GAAP net investment result to our tax equivalent result.

2021, we utilized a portion of the tax credits carried forward from the 2019 tax year.

We did not recognize any credit-related impairment losses in earnings or
non-credit impairment losses in OCI for the year ended December 31, 2021. For
the year ended December 31, 2020, we recognized $1.5 million of credit-related
impairment losses in earnings and a nominal amount of non-credit impairment
losses in OCI. The credit-related impairment losses recognized in 2020 primarily
related to corporate bonds in the energy and consumer sectors. Additionally,
2020 included credit-related impairment losses related to four corporate bonds
in various sectors, which were sold during 2020. The non-credit impairment
losses recognized during 2020 related to three corporate bonds in the energy and
consumer sectors.

We recognized $20.0 million of net investment gains for the year ended
December 31, 2021 which include approximately $1.9 million of net investment
gains related to investments acquired from NORCAL. Net investment gains in 2021
were driven by realized gains on the sale of certain available-for-sale fixed
maturities and other investments, partially offset by unrealized holding losses
resulting from decreases in the fair value on our equity portfolio. We
recognized $11.6 million of net investment gains for the year ended December 31,
2020, driven primarily by realized gains on the sale of certain
available-for-sale fixed maturities and equity investments, partially offset by
unrealized holding losses resulting from decreases in the fair value on our
equity portfolio due to the volatility in the global financial markets related
to COVID-19.

Operating Expenses

Corporate segment operating expenses were comprised as follows:

                                                       Year Ended December 31
                ($ in thousands)           2021          2020                Change
             Operating expenses         $ 36,007      $ 37,562      $ (1,555)       (4.1  %)
             Management fee offset        (9,366)      (14,133)        4,767       (33.7  %)
             Total                      $ 26,641      $ 23,429      $  3,212        13.7  %


Operating expenses decreased during the year ended December 31, 2021 as compared
to 2020 primarily due to a decrease in professional fees and, to a lesser
extent, the prior year effect of $0.5 million of one-time expenses incurred in
2020, partially offset by an increase in compensation-related costs. The
decrease in professional fees in 2021 was driven by a decrease in corporate
legal expenses. One-time expenses in 2020 were primarily comprised of employee
severance and early retirement benefits granted to certain employees. The
increase in compensation-related costs during 2021 was driven by higher amounts
accrued for performance-related incentive plans due to our improved performance
metrics and, to a lesser extent, an increase in share-based compensation
expenses attributable to the effect of an increase in the value of projected
awards in 2021 based upon the improvement of the associated performance metrics.

Operating subsidiaries within our Specialty P&C segment (excluding the acquired
operating subsidiaries of NORCAL) and our Workers' Compensation Insurance
segment are charged a management fee by the Corporate segment for services
provided to these subsidiaries. The management fee is based on the extent to
which services are provided to the subsidiary and the amount of premium written
by the subsidiary. Under the arrangement, the expenses associated with such
services are reported as expenses of the Corporate segment, and the management
fees charged are reported as an offset to Corporate operating expenses.
Fluctuations in the amount of premium written by each subsidiary can result in
corresponding variations in the management fee charged to each subsidiary during
a particular period. Due to organizational structure enhancements in our
Specialty P&C segment during 2020, the extent to which services are provided by
the Corporate segment to the operating subsidiaries within that segment
decreased effective January 1, 2021. Accordingly, we reduced the fee charged to
the operating subsidiaries within the Specialty P&C segment during 2021. There
were no changes to the extent to which services are provided by the Corporate
segment to the operating subsidiaries within our Workers' Compensation Insurance
segment in 2021.

Interest Expense

Consolidated interest expense for the years ended December 31, 2021 and 2020 was
comprised as follows:

                                                                           Year Ended December 31

*Includes accretion of approximately $1.2 million for the year ended December 31, 2021 which is recorded as an increase
to interest expense as a result of the difference between the recorded acquisition date fair value and the principal
balance of the Contribution Certificates associated with our acquisition of NORCAL.



Consolidated interest expense increased during 2021 as compared to 2020 driven
by the addition of interest expense on the Contribution Certificates associated
with our acquisition of NORCAL (See Note 2 and Note 13 of the Notes to
Consolidated Financial Statements) and, to a lesser extent, an increase in the
borrowings on our Revolving Credit Agreement. During the third quarter of 2021,
we repaid the balance outstanding on the Revolving Credit Agreement of $15.0
million and there were no outstanding borrowings on this agreement during 2020;
interest expense on the Revolving Credit Agreement in both 2021 and 2020
primarily reflected unused commitment fees. The increase in consolidated
interest expense for 2021 was partially offset by lower interest expense on our
Mortgage Loans. In 2021, we repaid the balance outstanding on our Mortgage Loans
of $35.3 million; interest expense on the Mortgage Loans during the current
period included the write-off of the related unamortized debt issuance costs
which were nominal in amount. In addition, consolidated interest expense during
2021 was impacted by the change in the fair value of our interest rate cap.

See further discussion of our interest rate cap agreement in Note 3 and further
discussion on our outstanding debt in Note 13 of the Notes to Consolidated
Financial Statements.

Taxes


Tax expense allocated to our Corporate segment includes U.S. tax only, which
would include U.S. tax expense incurred from our corporate membership in Lloyd's
of London. The U.K. tax expense incurred by the U.K. based subsidiaries of our
Lloyd's Syndicates segment is allocated to that segment. The SPCs at Inova Re,
one of our Cayman Islands reinsurance subsidiaries, have each made a 953(d)
election under the U.S. Internal Revenue Code and are subject to U.S. federal
income tax; therefore, tax expense allocated to our Corporate segment also
includes tax expense incurred from any SPC at Inova Re in which we have a
participation interest of 80% or greater as those SPCs are required to be
included in our consolidated tax return. Consolidated tax expense (benefit)
reflects the tax expense (benefit) of both segments and the tax impact of items
excluded from segment reporting, as shown in the table below:

                                                                           Year Ended December

*Represents the income tax benefit associated with the transaction-related
costs related to our acquisition of NORCAL that are not included in a segment
as we do not consider these costs in assessing the financial performance of
any of our operating or reportable segments. See Note 18 of the Notes to
Consolidated Financial Statements for a reconciliation of our segment results
to our consolidated results.


Listed below are the primary factors affecting our consolidated effective tax
rate for the years ended December 31, 2021 and 2020. The comparability of each
factor's impact on our effective tax rate is affected by the consolidated
pre-tax income recognized during 2021 as compared to the consolidated pre-tax
loss recognized during 2020. Factors that have the same directional impact on
income tax expense (benefit) in each period have an opposite impact on our
effective tax rate due to the effective tax rate being calculated based upon a
pre-tax income during the year ended December 31, 2021 versus the pre-tax loss
during the year ended December 31, 2020. These factors include the following:

                                                                                        Year Ended December 31

the gain on bargain purchase in Note 2 of the Notes to Consolidated Financial
Statements.

Our effective tax rates for 2021 and 2020, as shown in the table above, differed
from the statutory federal income tax rate of 21% in each respective year. The
most significant item impacting our effective tax rate for 2021 was the gain on
bargain purchase of $74.4 million related to the NORCAL acquisition, all of
which was non-taxable. See further discussion on the gain on bargain purchase in
Note 2 of the Notes to Consolidated Financial Statements. Additionally, our
effective tax rates for both 2021 and 2020 include the benefit recognized from
the tax credits transferred to us from our tax credit partnership investments.
Tax credits recognized for the year ended December 31, 2021 were $13.2 million
as compared to $17.9 million in 2020. While projected tax credits for 2021 are
less than 2020, they continue to have a significant impact on the effective tax
rate for 2021. For 2020, our effective tax rate was also affected by the
additional statutory tax rate differential of 14% on the carryback of our 2020
and 2019 NOLs to the 2015 and 2014 tax years, respectively, as a result of
changes made by the CARES Act to the NOL provisions of the tax law. Furthermore,
our pre-tax loss in 2020 included a $161.1 million goodwill impairment
recognized in relation to the Specialty P&C reporting unit during the third
quarter of 2020. Of the $161.1 million goodwill impairment, $149.6 million was
non-deductible for which no tax benefit was recognized, while the remaining
$11.5 million was deductible for which a 21% tax benefit was recognized on the
related income tax amortization. Consequently, the total impact of the goodwill
impairment on the effective tax rate in 2020 was approximately 14.5%. See
further discussion on this goodwill impairment in Notes 1 and 8 of the Notes to
Consolidated Financial Statements.
