Business Group Highlights

Asset Management: A global leader in both public and alternative asset classes through MFS and SLC Management

Asset Management underlying net income of $282 million was in line with prior year, driven by:

•MFS in line with prior year (up US$1 million): Higher fee income from average net assets ("ANA") mostly offset by higher expenses, which include fair value changes in management's participation in MFS shares. The MFS pre-tax net operating profit margin(1) improved to 37.2% for Q1'24 from 36.8% in the prior year due to higher ANA.

•SLC Management in line with prior year: Higher-fee related earnings offset by lower net seed investment income.Fee-related earnings(1) increased 1% driven by higher AUM, reflecting capital raising and deployment across the platform, offset by higher expenses. Fee-related earnings margin(1) was 23.9% for Q1'24, compared to 24.3% in the prior year.

Reported net income of $284 million increased $30 million or 12% from prior year, driven by a gain on the early termination of a distribution agreement partially offset by fair value changes in management's ownership of MFS shares.

Asset Management ended Q1'24 with $1,079 billion of AUM, consisting of $852 billion (US$630 billion) in MFS and $226 billion in SLC Management. Total Asset Management net outflows of $10.1 billion in Q1'24 reflected MFS net outflows of $11.7 billion (US$8.6 billion) partially offset by SLC Management net inflows of $1.5 billion.

During the first quarter, MFS celebrated its centennial anniversary. With a purpose of creating long-term value responsibly, MFS has been driven by a conviction to always do what's best for Clients, staying true to its active investment approach, core values and collaborative culture.

Our Asset Management businesses advanced their sustainable investing objectives with BentallGreenOak ("BGO") completing Ontario's first all-electric net zero carbon industrial building, owned by Sun Life.

•Lower earnings on surplus across all businesses primarily reflecting lower realized gains.

Reported net income of $290 million decreased $39 million or 12% from prior year, reflecting a prior year gain on sale of the sponsored markets business, partially offset by market-related impacts. The market-related impacts were primarily from interest rates, partially offset by real estate experience.

•Group - Health & Protection down US$30 million:Lower Dental results primarily reflecting the impact of Medicaid redeterminations following the end of the Public Health Emergency, and lower Group Benefits results primarily reflecting less favourable morbidity experience in medical stop-loss as utilization normalizes partially offset by strong revenue growth and favourable disability experience.

•Individual - Protection downUS$5 million: The inclusion of the UK payout annuity business(1) was offset by unfavourable credit experience in the quarter.

Reported net income of US$71 million decreased US$54 million or 43% ($97 million decreased $71 million or 42%) from prior year, reflecting the decrease in underlying net income and market-related impacts largely from real estate experience partially offset by favourable interest rate impacts.

U.S. group sales of US$142 million were down US$108 million or 43% ($191 million, down $148 million or 44%), reflecting comparable Group Benefits sales and lower Medicaid and commercial sales in Dental driven by large institutional sales in the prior year.

We continue to expand our capabilities and advance our strategy to help our members access the health care and coverage they need. In Employee Benefits, we are now offering Health Navigator, powered by PinnacleCare, to the large employer group benefits market. This personal health care navigation and advisory service helps members get the right medical diagnoses, doctors and treatments for their specific needs and helps improve health and productivity outcomes for employers.

Reported net income of $235 million increased $101 million or 75% from prior year, driven by a gain on partial sale of ABSLAMC and the increase in underlying net income, partially offset by market-related impacts. The market-related impacts were primarily from interest rates and lower equity markets in China, partially offset by real estate experience.

Asia's sales(2):

•Individual sales of $627 million were up 67%, primarily driven by higher sales in Hong Kong reflecting expanded distribution capabilities, partially offset by lower sales in China, Vietnam and India reflecting industry and market conditions.

•Wealth sales & asset management gross flows of $2 billion were down 14%, reflecting lower money market fund sales in the Philippines, lower Mandatory Provident Fund ("MPF") sales in Hong Kong, and lower sales in India primarily from fixed income funds.

New business CSM of $230 million in Q1'24 was up from $102 million in the prior year, primarily driven by sales in Hong Kong.

We are committed to delivering shareholder value, including building and realizing value through strategic investments. To meet regulatory obligations, in March, we sold 6.3% of our ownership interest in Aditya Birla Sun Life AMC Limited (BSE: ABSLAMC.BO and NSE: ABSLAMC.NS), unlocking value in our investment through generating a $98 million (post-tax $84 million) gain. Since the Initial Public Offering in 2021, Sun Life has generated gains of over $450 million (post-tax gains of over $350 million), while still retaining 30.2% ownership of the listed entity following the most recent sell-down. This highlights the value of ABSLAMC, reflecting a strong track record of performance, with an attractive product mix including fixed income, equities and alternatives, and a fast-growing retail presence in India.

We continue to build on our Purpose to help Clients achieve lifetime financial security and live healthier lives. Our focus on making a difference in the lives of our Clients was recognized by our Platinum award(3) for the most trusted brand in the life insurance industry in the Philippines. This is Sun Life Philippines' 15th year in a row to be recognized in the Trusted Brand Awards.

A. How We Report Our Results

Sun Life Financial Inc. ("SLF Inc."), its subsidiaries and, where applicable, its joint ventures and associates are collectively referred to as "the Company", "Sun Life", "we", "our", and "us". We manage our operations and report our financial results in five business segments: Canada, United States ("U.S."), Asset Management, Asia, and Corporate. Information concerning these segments is included in our annual and interim consolidated financial statements and accompanying notes ("Annual Consolidated Financial Statements" and "Interim Consolidated Financial Statements", respectively, and "Consolidated Financial Statements" collectively) and interim and annual management's discussion and analysis ("MD&A"). We prepare our unaudited Interim Consolidated Financial Statements using International Financial Reporting Standards ("IFRS"), the accounting requirements of the Office of the Superintendent of Financial Institutions ("OSFI") and in accordance with the International Accounting Standard ("IAS") 34 Interim Financial Reporting. Reported net income (loss) refers to Common shareholders' net income (loss) determined in accordance with IFRS.

Unless otherwise noted, all amounts are in Canadian dollars. Amounts in this document may be impacted by rounding. Certain 2023 results in the Drivers of Earnings and CSM Movement Analysis were refined to more accurately reflect how the business is managed.

Underlying net income by Business Types

Sun Life has a diversified mix of businesses and our earnings by business type supports the analysis of our results:

•Wealth & asset management: Sun Life's wealth & asset management businesses generate fee income and/or spread on investment products.

•Group - Health & Protection: Group businesses provide health and protection benefits to employer and government plan members. The products generally have shorter-term coverage periods, and more frequent repricing. The revenues are driven by premiums for coverage provided as well as fee-based earnings (i.e., Administrative Services Only plans, and dental fees).

•Individual - Protection: Generally, individual protection businesses have a longer-term profitability profile and are more sensitive to experience trends. The premiums include a margin for providing protection and are invested to eaa retuover the expected amounts required to fulfill insurance liabilities.

The following provides an overview of the business types in Sun Life's business segments/business groups:

Quarterly Comparison - Q1'24 vs. Q1'23

Underlying net income(1) of $875 milliondecreased $20 million from prior year, driven by:

•Wealth & asset management(1) down$3 million: Higher fee income offset by higher expenses in Asset Management, as well as lower net seed investment income in SLC Management.

•Group - Health & Protection(1) down$23 million: Less favourable morbidity experience in U.S. medical stop-loss and lower results in U.S. Dental primarily reflecting the impact of Medicaid redeterminations following the end of the Public Health Emergency, partially offset by strong revenue growth in U.S. Group Benefits, and business growth and improved disability experience in Canada.

•Individual - Protection(1) down$13 million: Lower earnings due to the sale of Sun Life UK(2) partially offset by business growth in Asia.

•Corporate expenses & other(1) $19 million decrease in net loss driven by lower financing costs.

Reported net income of $818 million increased $12 million from prior year, driven by:

•Gains on partial sale of ABSLAMC(3) and the early termination of a distribution agreement in Asset Management; largely offset by

•The prior year gain on sale of the sponsored markets business in Canada(4);

•Fair value changes in management's ownership of MFS(5) shares; and

•The decrease in underlying net income.

•Unfavourable real estate experience(6) was mostly offset by favourable interest rate impacts.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. First Quarter 2024 9

Foreign exchange translation led to a decrease of $4 million and $2 million in underlying net income and reported net income, respectively.

Underlying ROE was 16.0% and reported ROE was 15.0% (Q1'23 - 17.3% and 15.6%, respectively).

1.Market-related impacts

Market-related impacts represent the difference between actual versus expected market movements. Market-related impacts resulted in a decrease of $70 million to reported net income, primarily driven by real estate experience, partially offset by favourable interest rate impacts.

2.Assumption changes and management actions

The net impact of assumption changes and management actions was a decrease of $7 million to reported net income and includes methods and assumptions changes on insurance contracts as well as related impacts. These included various small enhancements.

3.Other adjustments

Other adjustments increased reported net income by $20 million, driven by gains on the partial sale of ABSLAMC and the early termination of a distribution agreement in Asset Management, largely offset by DentaQuest integration costs and amortization of acquired intangible assets, and SLC Management's acquisition-related liabilities(1).

4.Experience-related items

In the first quarter of 2024, notable experience items included:

•Unfavourable morbidity experience in U.S. Dental was mostly offset by favourable morbidity experience in U.S. group disability and medical stop-loss;

•Unfavourable expense experience largely in U.S. Dental;

•Unfavourable credit experience largely in Canada and the U.S.; and

•Other experience was favourable primarily from the U.S., Asia, and Canada.

5.Income taxes

The statutory tax rate is impacted by various tax items, such as lower taxes on income subject to tax in foreign jurisdictions, tax-exempt investment income, and other sustainable tax benefits.

The Pillar Two global minimum tax rules apply to us effective January 1, 2024 and have been substantively enacted in several jurisdictions in which we operate, including the UK, Ireland, Luxembourg and Vietnam, however the rules are not yet substantively enacted in Canada. The Pillar Two legislation is expected to increase the effective tax rate on underlying net income by approximately one to two percentage points. For additional information, refer to Note 9 of our Interim Consolidated Financial Statements for the period ended March 31, 2024.

The Q1'24 effective income tax rate(2) on underlying net income and reported net income was 16.2% and 21.8% respectively.

6.Impacts of foreign exchange translation

Foreign exchange translation led to a decrease of $4 million and $2 million in underlying net income and reported net income, respectively.

(1)Amounts relate to acquisition costs for our SLC Management affiliates, BentallGreenOak, InfraRed Capital Partners, Crescent Capital Group LP and Advisors Asset Management Inc., which include the unwinding of the discount for Other financial liabilities.

(2)Our effective income tax rate on reported net income is calculated using Total income (loss) before income taxes, as detailed in Note 9 of our Interim Consolidated Financial Statements for the period ended March 31, 2024. Our effective income tax rate on underlying net income is calculated using pre-tax underlying net income, as detailed in section N - Non-IFRS Financial Measures in this document, and the associated income tax expense.

Total wealth sales & asset management gross flows increased $0.5 billion from prior year ($0.7 billion(1), excluding foreign exchange translation).

•Asset Management gross flows were in line with prior year, as higher gross flows in MFS were mostly offset by lower gross flows in SLC Management.

•Canada wealth sales & asset management gross flows increased $1.0 billion or 32%, driven by higher mutual fund sales in Individual Wealth and higher defined benefit solution and defined contribution sales in Group Retirement Services ("GRS").

•Asia wealth sales & asset management gross flows decreased $0.3 billion(1) or 13%(1), reflecting lower money market fund sales in the Philippines, lower Mandatory Provident Fund ("MPF") sales in Hong Kong, and lower sales in India primarily from fixed income funds.

Total group health & protection sales increased $19 million or 4% from prior year ($20 million(1) or 4%(1), excluding foreign exchange translation).

•Canada group sales increased $166 million or 114%, driven by higher large case sales.

•U.S. group sales decreased $147 million(1) or 43%(1), reflecting comparable Group Benefits sales and lower Medicaid and commercial sales in Dental driven by large institutional sales in the prior year.

Total individual protection sales increased $246 million or 48% from prior year ($252 million(1) or 49%(1), excluding foreign exchange translation).

•Canada individual sales decreased $6 million or 4%, reflecting lower participating whole life insurance sales.

•Asia individual sales increased $258 million(1) or 69%(1), primarily driven by higher sales in Hong Kong reflecting expanded distribution capabilities, partially offset by lower sales in China, Vietnam and India reflecting industry and market conditions.

New business CSM represents growth derived from sales activity in the period. The impact of new insurance business drove a $347 million increase in CSM, compared to new business CSM of $232 million in the prior year, primarily driven by strong sales in Asia in Hong Kong.

(1)This change excludes the impacts of foreign exchange translation. For more information about these non-IFRS financial measures, see section

1. Life Insurance Capital Adequacy Test

The Office of the Superintendent of Financial Institutions has developed the regulatory capital framework referred to as the Life Insurance Capital Adequacy Test for Canada. LICAT measures the capital adequacy of an insurer using a risk-based approach and includes elements that contribute to financial strength through periods when an insurer is under stress as well as elements that contribute to policyholder and creditor protection wind-up.

SLF Inc. is a non-operating insurance company and is subject to the LICAT guideline. Sun Life Assurance, SLF Inc.'s principal operating life insurance subsidiary, is also subject to the LICAT guideline.

SLF Inc.'s LICAT ratio of 148% as at March 31, 2024 decreased one percentage point compared to December 31, 2023, driven by shareholder dividend payments and share buybacks, mostly offset by reported net income and M&A(1) activity.

Sun Life Assurance's LICAT ratio of 142% as at March 31, 2024 increased one percentage point compared to December 31, 2023, driven by reported net income and M&A activity, mostly offset by dividend payments to SLF Inc.

The Sun Life Assurance LICAT ratios in both periods are well above OSFI's supervisory ratio of 100% and regulatory minimum ratio of 90%.

2. Capital

Our total capital consists of subordinated debt and other capital instruments, CSM, equity in the participating account and total shareholders' equity which includes common shareholders' equity, preferred shares and other equity instruments, and non-controlling interests. As at March 31, 2024, our total capital was $43.2 billion, an increase of $0.8 billion compared to December 31, 2023. The increase to total capital included reported net income of $818 million, an increase of $355 million in CSM, and the favourable impacts of foreign exchange translation of $292 million included in other comprehensive income (loss) ("OCI"). This was partially offset by the payment of $456 million of dividends on common shares of SLF Inc. ("common shares") and a decrease of $174 million from the repurchase and cancellation of common shares.

Our capital and liquidity positions remain strong with a LICAT ratio of 148% at SLF Inc., a financial leverage ratio of 21.1%(1) and $1.5 billion in cash and other liquid assets(1) as at March 31, 2024 in SLF Inc.(2) (December 31, 2023 - $1.6 billion).

Normal Course Issuer Bids

On August 29, 2023, SLF Inc. commenced its previously announced normal course issuer bid, which remains in effect until August 28, 2024, or such earlier date as SLF Inc. may determine, or until SLF Inc. has purchased an aggregate of 17 million common shares under the bid ("the NCIB"). During the first quarter of 2024, SLF Inc. purchased approximately 2.4 million common shares at a total cost of $174 million. All common shares purchased under SLF Inc.'s NCIB were subsequently cancelled. As at March 31, 2024, the total aggregate shares cancelled and associated cost under SLF Inc.'s NCIB were 5.2 million and $360 million, respectively.

Profitability

Quarterly Comparison - Q1'24 vs. Q1'23

Asset Management underlying net income of $282 million was in line with prior year, driven by:

•SLC Management in line with prior year: Higher-fee related earnings offset by lower net seed investment income. Fee-related earnings(1) increased 1% driven by higher AUM, reflecting capital raising and deployment across the platform, offset by higher expenses.

H. Investments

Total general fund invested assets of $173.4 billion as at March 31, 2024, were down $0.9 billion from December 31, 2023. The decrease was primarily due to decline in net fair value from rising interest rates, partially offset by favourable impacts from foreign exchange translation. Our general fund invested assets are well-diversified across investment types, geographies and sectors with the majority of our portfolio invested in high quality fixed income assets.

The following table sets out the composition of our general fund invested assets:(1)


March 31, 2024	December 31, 2023
($ millions)	Carrying value	% of Total carrying value	Carrying value	% of Total carrying value
Cash, cash equivalents and short-term securities	11,265	6%	13,173	8%
Debt securities	75,887	44%	75,493	43%
Equity securities	7,750	4%	7,138	4%
Mortgages and loans	54,798	32%	54,600	31%
Derivative assets	1,504	1%	2,183	1%
Other invested assets	12,656	7%	12,018	7%
Investment properties	9,555	6%	9,723	6%
Total invested assets	173,415	100%	174,328	100%

(1)The values and ratios presented are based on the fair value of the respective asset categories. Generally, the carrying values for invested assets are equal to their fair values. For invested assets supporting insurance contracts, in the event of default, if the amounts recovered are insufficient to satisfy the related insurance contract liability cash flows that the assets are intended to support, credit exposure may be greater than the carrying value of the assets.

1. Debt Securities

The debt securities portfolio is actively managed through a regular program of purchases and sales aimed at optimizing yield, quality, and liquidity, while ensuring that it remains well-diversified and duration-matched to insurance contract liabilities. As at March 31, 2024, with the exception of certain countries where we have business operations, including Canada, the United States and the Philippines, our exposure to debt securities from any single country did not exceed 1% of total invested assets.

Debt Securities by Geography

The carrying value of our debt securities by geographic location is presented in the following table.


March 31, 2024	December 31, 2023
($ millions)	FVTPL debt securities	FVOCI debt securities	Total	% of Total	FVTPL debt securities	FVOCI debt securities	Total	% of Total

Total debt securities	61,598	14,289	75,887	100%	61,180	14,313	75,493	100%

Our gross unrealized losses as at March 31, 2024 for FVTPL and FVOCI debt securities were $7,219 million and $635 million, respectively (December 31, 2023 - $6,119 million and $615 million, respectively). The increase in gross unrealized losses was largely due to the impact from rising interest rates.

Debt Securities by Credit Rating

Debt securities with a credit rating of "A" or higher represented 72% of the total debt securities as at March 31, 2024, consistent with December 31, 2023. Debt securities with a credit rating of "BBB" or higher represented 99% of total debt securities as at March 31, 2024, consistent with December 31, 2023.

(1)The geographic location for mortgages is based on the location of the property and for loans it is based on the country of the creditor's parent.

Mortgage Portfolio

As at March 31, 2024, we held $14.0 billion of mortgages (December 31, 2023 - $14.1 billion). Our mortgage portfolio consists entirely of commercial mortgages, as presented in the following table.


March 31, 2024	December 31, 2023
($ millions)	Insured	Uninsured	Total	Insured	Uninsured	Total
Mortgages:
Retail	-	2,530	2,530	-	2,558	2,558
Office	-	2,724	2,724	-	2,754	2,754

% of Total mortgages	28%	72%	100%	28%	72%	100%

Our mortgage portfolio consists entirely of commercial mortgages, including retail, office, multi-family, and industrial properties. As at
March 31, 2024, 34% of our commercial mortgage portfolio consisted of multi-family residential mortgages; there are no single-family residential mortgages. Our uninsured commercial portfolio had a weighted average loan-to-value ratio of approximately 52% as at
March 31, 2024 (December 31, 2023 - 52%). While we generally limit the maximum loan-to-value ratio to 75% at issuance, we may invest in mortgages with a higher loan-to-value ratio in Canada if the mortgage is insured by the Canada Mortgage and Housing Corporation ("CMHC"). The estimated weighted average debt service coverage for our uninsured commercial portfolio is 1.75 times. Of the $3.7 billion of multi-family residential mortgages in the Canadian commercial mortgage portfolio, 93% were insured by the CMHC.

As at March 31, 2024, we held $40.8 billion of loans (December 31, 2023 - $40.5 billion). Private placement loans provide diversification by type of loan, industry segment and borrower credit quality. The private placement loan portfolio consists of senior secured and unsecured loans to large- and mid-market corporate borrowers, securitized lease/loan obligations secured by a variety of assets, and project finance loans in sectors such as power and infrastructure.

As at March 31, 2024, our impaired mortgages and loans, net of allowances for losses, were $19 million (December 31, 2023 - $7 million).

3. Derivatives

The values associated with our derivative instruments are presented in the following table. Notional amounts serve as the basis for payments calculated under derivatives contracts and are generally not exchanged.


($ millions)	March 31, 2024	December 31, 2023
Net fair value asset (liability)	(199)	872
Total notional amount	71,796	70,421
Credit equivalent amount(1)	1,346	1,594
Risk-weighted credit equivalent amount(1)	30	34

(1)Amounts presented are net of collateral received.

The net fair value of derivatives was a liability of $199 million as at March 31, 2024 (December 31, 2023 - asset of $872 million). The decrease in net fair value was driven by a decrease in interest rate contracts primarily due to upward shifts in yield curves and decrease in foreign exchange contracts due to the depreciation of the Canadian dollar against U.S. dollar.

24 Sun Life Financial Inc. First Quarter 2024 MANAGEMENT'S DISCUSSION AND ANALYSIS

The total notional amount of our derivatives increased to $71.8 billion as at March 31, 2024 (December 31, 2023 - $70.4 billion). The change in notional amount is mainly attributable to an increase in interest rate contracts used for duration matching and foreign exchange contracts used for hedging foreign currency assets.

4. Investment Properties

As at March 31, 2024, we held $9.6 billion of investment properties (December 31, 2023 - $9.7 billion). The decrease in our investment property portfolio is predominantly driven by declines in market value, mainly in the office and U.S. industrial sectors, and property sales in the Canadian industrial sector.

5. Loss Allowance and Provision for Credit Losses

The balance of the total loss allowance was $84 million as at March 31, 2024 (December 31, 2023- $89 million) and the provision for credit losses decreased by $5 million for the three months ended March 31, 2024 (increased by $8 million for the three months ended
March 31, 2023).

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. First Quarter 2024 25

I. Risk Management

We have established a Risk Management Framework to assist in identifying, measuring, managing, monitoring and reporting risks. The Risk

Management Framework covers all risks and these have been grouped into six major categories: market, insurance, credit, business and strategic, operational and liquidity risks. Through our enterprise risk management processes, we oversee the various risk factors identified in the Risk Management Framework and provide reports to senior management and to the Board Committees at least quarterly. Our enterprise risk management processes and risk factors are described in our 2023 Annual MD&A and AIF.

This section includes our disclosure on market risks and should be read in conjunction with our unaudited Interim Consolidated Financial Statements for the quarter ended March 31, 2024. When referring to segregated funds in this section, it is inclusive of segregated fund guarantees, variable annuities and investment products.

Equity Risk

Equity risk is the potential for financial loss arising from declines or volatility in public or private equity market prices. We are exposed to equity risk from a number of sources.

We generate revenue in our asset management businesses and from certain insurance and annuity contracts where fees are levied on account balances that are affected directly by equity market levels. Accordingly, we have further exposure to equity risk as adverse fluctuations in the market value of such assets will result in corresponding adverse impacts on revenue, income, and the contractual service margin. In addition, declining and volatile equity markets may have a negative impact on sales and redemptions (surrenders) in these businesses, and this may result in further adverse impacts on net income, the contractual service margin, and capital.

A portion of our exposure to equity risk arises in connection with benefit guarantees on segregated fund products, some participating insurance contracts, some adjustable insurance contracts, and some universal life contracts. These benefit guarantees may be triggered upon death, maturity, withdrawal or annuitization. The cost of providing these guarantees is uncertain and depends upon a number of factors, including general capital market conditions, our hedging strategies, policyholder behaviour and mortality experience, each of which may result in negative impacts on net income, the contractual service margin, and capital.

We also have direct exposure to equity markets from the investments supporting other general account liabilities, surplus, and employee benefit plans. These exposures fall within our risk-taking philosophy and appetite, and are therefore generally not hedged.

Interest Rate and Spread Risk

Interest rate and spread risk includes the potential for financial loss arising from changes in the value of insurance and investment contract liabilities and financial assets due to changes or volatility in interest rates or spreads. In practice, when asset cash flows and the policy obligations they support are not matched, this may result in the need to either sell assets to meet policy payments and expenses or reinvest excess asset cash flows in unfavourable interest rate or credit spread environments. This risk is managed in our asset-liability management program. Details of the asset-liability management program are discussed under the heading "Market Risk Management Governance and Control" in section K - Risk Management in the 2023 Annual MD&A.

Our primary exposure to interest rate and spread risk arises from insurance and investment contracts that contain guarantees in the form of minimum crediting rates, maximum premium rates, settlement options, guaranteed annuitization options and minimum benefits. If investment returns fall below guaranteed levels, we may be required to increase liabilities or capital in respect of these contracts. The guarantees attached to these products may be applicable to both past premiums collected and future premiums not yet received. Segregated fund contracts provide benefit guarantees that are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. Exposure to guarantees is managed within our risk appetite limits through our asset-liability management program, which may include the use of hedging strategies utilizing interest rate derivatives such as interest rate floors, swaps, futures and swaptions. The impact of these guarantees on net income, contractual service margin, and capital are included in the disclosed market risk sensitivities.

Significant changes or volatility in interest rates or spreads could have a negative impact on sales of certain insurance and annuity products, and adversely impact the expected patteof redemptions (surrenders) on existing policies. Increases in interest rates or widening credit spreads may increase the risk that policyholders will surrender their contracts, potentially forcing us to liquidate assets at a loss. While we have established hedging programs in place and our insurance and annuity products often contain surrender mitigation features, these may not be sufficient to fully offset the adverse impact of changes in interest rates or spreads. Declines in interest rates or narrowing spreads can result in compression of the net spread between interest earned on investments and interest credited to policyholders. Declines in interest rates or narrowing spreads can also result in increased asset calls, mortgage prepayments, and net reinvestment of positive cash flows at lower yields, and therefore adversely impact our profitability and financial position. Negative interest rates may additionally result in losses on our cash and short-term deposits and low or negative returns on our fixed income assets impacting our profitability.

We also have direct exposure to interest rates and spreads from investments supporting other general account liabilities, surplus and employee benefit plans. Higher interest rates or wider spreads will reduce the value of our existing assets. Conversely, lower interest rates or a narrowing of spreads will result in reduced investment income on new fixed income asset purchases. These exposures fall within our risk-taking philosophy and appetite and are therefore generally not hedged.

A sustained low interest rate environment may additionally adversely impact our net income, CSM, capital, and our ability to implement our business strategy and plans. This may be realized through lower sales, less profitable new business, changes in the patteof redemptions on existing policies, among other impacts.

26 Sun Life Financial Inc. First Quarter 2024 MANAGEMENT'S DISCUSSION AND ANALYSIS

Real Estate Risk

Real estate risk is the potential for financial loss arising from fluctuations in the value of, or future cash flows from, our investments in real estate. We are exposed to real estate risk and may experience financial losses resulting from the direct ownership of real estate investments or indirectly through fixed income investments secured by real estate property, leasehold interests, ground rents, and purchase and leaseback transactions. Real estate price risk may arise from external market conditions, inadequate property analysis, inadequate insurance coverage, inappropriate real estate appraisals, or from environmental risk exposures. We hold real estate investments that support general account liabilities and surplus, and fluctuations in value will affect our net income, CSM, and capital. A material and sustained increase in interest rates may lead to deterioration in real estate values.

Foreign Currency Risk

Foreign currency risk is the result of mismatches in the currency of our assets and liabilities (inclusive of capital), and cash flows. This risk may arise from a variety of sources such as foreign currency transactions and services, foreign currency hedging, investments denominated in foreign currencies, investments in foreign subsidiaries and net income from foreign operations. Changes or volatility in foreign exchange rates, including a change to currencies that are fixed in value to another currency, could adversely affect our net income, contractual service margin and capital.

As an international provider of financial services, we operate in a number of countries, with revenues and expenses denominated in several local currencies. In each country in which we operate, we generally maintain the currency profile of assets to match the currency of liabilities and required capital. This approach provides an operational hedge against disruptions in local operations caused by currency fluctuations. Foreign currency derivative contracts such as currency swaps and forwards are used as a risk management tool to manage the currency exposure in accordance with our Asset Liability Management Policy. As at March 31, 2024 and December 31, 2023, the Company did not have a material foreign currency risk exposure.

Changes in exchange rates can affect our net income and surplus when financial results in functional currencies are translated into Canadian dollars. Net income earned outside of Canada is generally not currency hedged and a weakening in the local currency of our foreign operations relative to the Canadian dollar can have a negative impact on our net income reported in Canadian currency. A strengthening in the local currency of our foreign operations relative to the Canadian dollar would have the opposite effect. Regulatory capital ratios could also be impacted by changes in exchange rates.

Inflation Risk

Inflation risk is the potential for financial loss arising from changes in inflation rates. This risk results from insurance contract liabilities that are linked to market measures of inflation such as the Consumer Price Index. The primary sources for this risk exposure are from certain group and retail annuity contracts and group long term disability contracts. In these contracts, the annuity and disability benefit payments may be linked to an indexing formula containing an inflation price index. Benefit payments linked to inflation indices may also include various caps, floors and averaging mechanisms that vary across product designs.

Exposure to inflation risk is managed within our asset-liability management program, primarily by investing in inflation linked assets to match liability exposures.

i. Market Risk Sensitivities

We use a variety of methods and measures to manage and quantify our market risk exposures. These include duration and key rate duration management, convexity measures, cash flow gap analysis, scenario testing, and sensitivity testing of earnings and regulatory capital ratios.

The measurement of liabilities and assets are affected by the level of equity market performance, interest rates, credit and swap spreads and other market risk variables. The following sections set out the estimated immediate impact on, or sensitivity of, our net income(1), contractual service margin, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in market variables as at March 31, 2024 and December 31, 2023.

The estimated sensitivities in the tables below reflect the impact of market movements on insurance contracts and investment contracts, assets backing insurance contracts, assets backing investment contracts, assets backing the surplus segment, and seed investments in our asset management subsidiaries.

Net income sensitivities to equity and real estate market movements are driven primarily by changes in the value of investments backing general account liabilities and surplus. Net income sensitivities to interest rates and spreads are driven by the net impact on liabilities and the assets backing them. Lower interest rates or a narrowing of spreads will result in increased liabilities for insurance contracts, offset by increased values of the assets backing general account liabilities. Higher interest rates or a widening of spreads will result in decreased liabilities for insurance contracts, offset by decreased values of the assets backing general account liabilities. Further detail on the impact of changes or volatility in market prices on assets and liabilities is provided under the headings "Equity Risk", "Interest Rate and Spread Risk", and "Real Estate Risk" above.

(1)Net income in section I - Risk Management in this document refers to common shareholders' net income.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. First Quarter 2024 27

OCI sensitivities are impacted by changes in the market value of assets classified as FVOCI. The market value of FVOCI fixed income assets, which are held primarily in our surplus and investment contract segments, increases with lower interest rates or a narrowing of spreads, and decreases with higher interest rates or a widening of spreads.

As these market risk sensitivities reflect an instantaneous impact on net income, CSM, OCI and SLF Inc.'s LICAT ratio, they do not include impacts over time such as the effect on fee income in our asset management businesses.

Refer to Additional Cautionary Language and Key Assumptions Related to Sensitivities in this section for important additional information regarding these estimates.

1. Private and Public Equity Market Sensitivities

The following table sets out the estimated immediate impact on, or sensitivity of, our net income, CSM, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in public or private equity market prices as at March 31, 2024 and December 31, 2023. The sensitivities shown outline the impact of the same percentage increase or decrease applied to each of private equity and public equity. About two-thirds of our expected net income sensitivity to changes in equity markets is driven by investments in private equity.

(1)Represents the respective change across all equity exposures as at March 31, 2024 and December 31, 2023. Due to the impact of active management, basis risk, and other factors, realized sensitivities may differ significantly from expectations. Sensitivities include the impact of re-balancing equity hedges for hedging programs at 2% intervals (for 10% changes in equity markets) and at 5% intervals (for 25% changes in equity markets). (2)The market risk sensitivities include the estimated impact of our hedging programs in effect as at March 31, 2024 and December 31, 2023, and include new business added and product changes implemented prior to such dates. (3)Net income, CSM and OCI sensitivities have been rounded in increments of $25 million. The sensitivities exclude the market impacts on the income from our joint ventures and associates, which we account for on an equity basis. (4)The market risk OCI sensitivities exclude the impact of changes in the defined benefit obligations and plan assets. (5)The LICAT sensitivities illustrate the impact on SLF Inc. as at March 31, 2024 and December 31, 2023. LICAT ratios are rounded in increments of 0.5%.

2. Interest Rate Sensitivities

The following table sets out the estimated immediate impact on, or sensitivity of, our net income, CSM, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in interest rates as at March 31, 2024 and December 31, 2023.


($ millions, unless otherwise noted)	As at March 31, 2024	As at December 31, 2023
Change in Interest Rates(1)(2)(3)	50 basis point decrease	50 basis point increase	50 basis point decrease	50 basis point increase
Potential impact on net income (after-tax)	(25)	25	(25)	50

Potential impact on LICAT ratio(5)	2.0% point increase	1.0% point decrease	1.5% point increase	1.5% point decrease
(1)Interest rate sensitivities assume a parallel shift in assumed interest rates across the entire yield curve as at March 31, 2024 and December 31, 2023 with no change to the ultimate risk-free rate. Variations in realized yields based on factors such as different terms to maturity and geographies may result in realized sensitivities being significantly different from those illustrated above. Sensitivities include the impact of re-balancing interest rate hedges for hedging programs at 10 basis point intervals (for 50 basis point changes in interest rates). (2)The market risk sensitivities include the estimated impact of our hedging programs in effect as at March 31, 2024 and December 31, 2023, and include new business added and product changes implemented prior to such dates. (3)Net income, CSM and OCI sensitivities have been rounded in increments of $25 million. The sensitivities exclude the market impacts on the income from our joint ventures and associates, which we account for on an equity basis. (4)The market risk OCI sensitivities exclude the impact of changes in the defined benefit obligations and plan assets. (5)The LICAT sensitivities illustrate the impact on SLF Inc. as at March 31, 2024 and December 31, 2023. The sensitivities reflect the worst scenario as at March 31, 2024 and assume that a scenario switch does not occur in the quarter. LICAT ratios are rounded in increments of 0.5%.

The above sensitivities were determined using a 50 basis point change in interest rates and a 10% and 25% changes in our equity markets because we believe that these market shocks were reasonably possible as at March 31, 2024. Significant changes in market variables may result in other than proportionate impacts on our sensitivities.

3. Credit Spread and Swap Sensitivities

Credit spread sensitivities reflect the impact of changes in credit spreads on our asset and liability values (including provincial government bonds, corporate bonds, and other fixed income assets). Swap spread sensitivities reflect the impact of changes in swap spreads on swap-based derivative positions and liability values.

The following tables set out the estimated immediate impact on, or sensitivity of, our net income, CSM, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in credit spreads and our net income, CSM, and OCI to certain changes in swap spreads as at March 31, 2024 and December 31, 2023.

(1)The credit spread sensitivities assume a parallel shift in the indicated spreads across the entire term structure with no change to the ultimate liquidity premium. The sensitivities reflect a floor of zero on credit spreads where the spreads are not currently negative. Variations in realized spread changes based on different terms to maturity, geographies, asset classes and derivative types, underlying interest rate movements, and ratings may result in realized sensitivities being significantly different from those provided above. (2)Net income, CSM, and OCI sensitivities have been rounded in increments of $25 million. (3)The market risk OCI sensitivities exclude the impact of changes in the defined benefit obligations and plan assets. (4)The LICAT sensitivities illustrate the impact on SLF Inc. as at March 31, 2024 and December 31, 2023. The sensitivities reflect the worst scenario as of March 31, 2024 and assume that a scenario switch does not occur in the quarter. LICAT ratios are rounded in increments of 0.5%.

(1)Net income, CSM, and OCI sensitivities have been rounded in increments of $25 million.

LICAT Interest Rate Scenario Switch

The LICAT interest rate risk is assessed under four different interest rate scenarios, and the scenario leading to the highest capital requirement is chosen as the worst scenario for each geographic region as defined by the LICAT guideline. Changes and interaction between the level and term movements in interest rates and credit spreads can shift the interest rate scenario applied in the LICAT calculation causing a discontinuity where capital requirements change materially. In 2020, OSFI updated the LICAT guideline for interest rate risk requirements for participating businesses to be smoothed over six quarters. As a result, the actual impact to the LICAT ratio from participating businesses in any quarter will reflect the scenarios from current quarter as well as the prior five quarters and switching between the scenarios would have the effect of offsetting the previous impacts over time. It should be noted that switching of the scenario can also change the direction of our sensitivities.

For SLF Inc., assuming no further scenario switches, no additional LICAT ratio impact is expected over the next five quarters.

In Q1'24, Sun Life Assurance experienced a scenario switch, resulting in no change to the LICAT ratio. For Sun Life Assurance, assuming no further scenario switches, the remaining impact of one-half percentage point is expected to increase the LICAT ratio over the next five quarters.

5. Additional Cautionary Language and Key Assumptions Related to Sensitivities

Our market risk sensitivities are measures of our estimated change in net income, OCI, CSM and LICAT ratio for changes in market risk variables described above, based on market risk variables and business in force as at the reporting date. These sensitivities are calculated independently for each risk factor, generally assuming that all other risk variables stay constant. The sensitivities do not take into account indirect effects such as potential impacts on goodwill impairment or valuation allowances on deferred tax assets.

We have provided measures of our net income sensitivity to instantaneous changes in equity markets, interest rates, credit spreads, swap spreads, real estate price levels, and capital sensitivities to changes in equity price levels, interest rates and credit spreads. The LICAT ratio and CSM sensitivities are non-IFRS financial measures, and for additional information, see section N - Non-IFRS Financial Measures in this document. The cautionary language which appears in this section is applicable to all net income, CSM, OCI and LICAT ratio sensitivities.

Actual results can differ materially from these estimates for a variety of reasons, including differences in the patteor distribution of the market shocks, the interaction between these risk factors, model error, or changes in other assumptions such as business mix, effective tax rates, policyholder behaviour, currency exchange rates and other market variables relative to those underlying the calculation of these sensitivities. The extent to which actual results may differ from the indicative ranges will generally increase with larger movements in risk variables. Our sensitivities as at December 31, 2023 have been included for comparative purposes only.

Sensitivities to interest rates and credit spreads assume a parallel shift in assumed interest rates across the entire yield curve or a parallel shift in the indicated spreads across the entire term structure, with no change to the ultimate risk-free rate or ultimate liquidity premium. Realized sensitivities may be significantly differently from those illustrated based on factors such as different terms to maturity, geographies, asset classes and derivative types, and ratings.

The sensitivities reflect the composition of our assets and liabilities as at March 31, 2024 and December 31, 2023, respectively. Changes in these positions due to new sales or maturities, asset purchases/sales, or other management actions could result in material changes to these reported sensitivities. In particular, these sensitivities reflect the expected impact of hedging activities based on the hedging programs in place as at the respective calculation dates. The actual impact of hedging activity can differ materially from that assumed in the estimated sensitivities due to ongoing hedge re-balancing activities, changes in the scale or scope of hedging activities, changes in the cost or general availability of hedging instruments, basis risk (i.e., the risk that hedges do not exactly replicate the underlying portfolio experience), model risk, and other operational risks in the ongoing management of the hedge programs or the potential failure of hedge counterparties to perform in accordance with expectations.

Our hedging programs may themselves expose us to other risks, including basis risk, volatility risk, and increased levels of derivative counterparty credit risk, liquidity risk, model risk and other operational risks. These factors may adversely impact the net effectiveness, costs, and financial viability of maintaining these hedging programs and therefore adversely impact our profitability and financial position. While our hedging programs are intended to mitigate these effects (e.g., hedge counterparty credit risk is managed by maintaining broad diversification, dealing primarily with highly-rated counterparties, and transacting through over-the-counter ("OTC") contracts cleared through central clearing houses, exchange-traded contracts or bilateral OTC contracts negotiated directly between counterparties that include credit support annexes), residual risk, potential reported earnings and capital volatility remain.

The sensitivities are based on methods and assumptions in effect as at March 31, 2024 and December 31, 2023, as applicable. Changes in the regulatory environment, assumptions or methods used to measure assets and liabilities after those dates could result in material changes to the estimated sensitivities. Changes in market risk variables in excess of the changes illustrated may result in other than proportionate impacts.

The sensitivities reflect the CSM as at March 31, 2024 and December 31, 2023. For insurance contracts measured using the variable fee approach ("VFA"), where the change in the effect of the time value of money and financial risk not arising from the underlying items adjusts the CSM, changes in the CSM balance will affect the sensitivity of income to changes in market risk variables.

Our LICAT sensitivities may be non-linear and can change due to the interrelationship between market rates and spreads, actuarial assumptions and our LICAT calculations.

For the reasons outlined above, our sensitivities should only be viewed as indicative estimates of the underlying sensitivities of each factor under these specialized assumptions, and should not be viewed as predictors of our future income, OCI, CSM or capital. Given the nature of these calculations, we cannot provide assurance that actual impacts will be consistent with the estimates provided.

Information related to market risk sensitivities should be read in conjunction with the information contained in section

N - Accounting and Control Matters - 1 - Critical Accounting Policies and Estimates in the 2023 Annual MD&A. Additional information on market risk can be found in Note 2 and Note 6 of the 2023 Annual Consolidated Financial Statements and the Risk Factors section in the 2023 AIF.

Fee income	2,012	2,065	1,901
Total revenue	6,875	18,684	11,983

Total revenue decreased $5.1 billion compared to the prior year, primarily driven by net investment losses from fair value changes of invested assets. By business group, total revenue reflected net investment losses in Canada, the U.S. and Asia partially offset by higher insurance revenue primarily in the U.S.

2. Changes in the Statements of Financial Position and in Shareholders' Equity

Total general fund assets were $205.0 billion as at March 31, 2024 (December 31, 2023 - $204.8 billion).

The net liabilities balance for insurance contracts issued(1) was $134.7 billion as at March 31, 2024 (December 31, 2023 - $135.5 billion), primarily reflecting insurance finance income and expenses and the change in insurance service result, partially offset by foreign currency translation and cash flows.

Total shareholders' equity, including preferred shares and other equity instruments, is $24.0 billion as at March 31, 2024 (December 31, 2023 - $23.6 billion). The change in total shareholders' equity included:

(i)total shareholders' net income of $838 million, before preferred share dividends of $20 million; and

(ii)favourable impacts from foreign exchange translation of $292 million included in OCI; partially offset by

(iii)common share dividend payments of $456 million; and

(iv)a decrease of $174 million from the repurchase and cancellation of common shares.

As at April 26, 2024, SLF Inc. had 581,252,131 common shares, 3,641,145 options to acquire SLF Inc. common shares, and 52,200,000 Class A Shares outstanding.

Net cash, cash equivalents and short-term securities, end of period	11,123	13,173	10,832

Our operating activities generate cash flows which include net premiums, net investment income, fee income, and the sale and maturity of investments. They are the principal source of funds to pay for policyholder claims and benefits, commissions, operating expenses, and the purchase of investments. Cash flows used in investing activities primarily include transactions related to associates, joint ventures and acquisitions. Cash flows provided by and used in financing activities largely reflect capital transactions including payments of dividends, the issuance and repurchase of shares, as well as the issuance and retirement of debt instruments and preferred shares.

Q1'24 cash flows used in financing activities were higher year-over-year primarily due to borrowing from credit facilities in the prior year and the impact from common shares purchased for cancellation in the current year.

Fourth Quarter 2023

Underlying net income of $983 million increased $91 million or 10% from prior year, driven by:

•Wealth & asset managementup$27 million: Higher Asset Management fee-related earnings and higher investment income driven by volume growth and an increase in yields.

•Group - Health & Protection up$44 million:Business premium growth in the U.S. and Canada, improved disability experience in Canada, and higher investment contributions in the U.S., partially offset by lower results in U.S. Dental.

•Individual - Protectionup$53 million: Business growth reflecting good sales momentum in Asia, and higher investment contributions in Canada, partially offset by lower earnings due to the sale of Sun Life UK.

•Corporate expenses & other$(33) million increase in net loss driven by higher operating expenses reflecting business growth and continued investments in the business, partially offset by a lower effective tax rate.

•Higher earnings on surplus primarily driven by higher net interest income and lower realized losses.

Reported net income of $749 million decreased $416 million or 36%, driven by unfavourable market-related impacts primarily reflecting interest rates and real estate experience, the prior year impact of the Canada Tax Rate Change, and fair value changes in management's ownership of MFS shares; partially offset by the increase in underlying net income, the impact of the Bermuda Corporate Income Tax Change; and lower DentaQuest integration costs.

Third Quarter 2023

Underlying net income of $930 milliondecreased $19 million or 2%, driven by:

•Wealth & asset managementup$38 million: Higher investment income driven by volume growth and an increase in yields, and higher Asset Management fee-related earnings.

•Group - Health & Protectionup$4 million: Strong revenue growth across all U.S. businesses and better disability experience in Canada, largely offset by health and protection experience in the U.S., and lower fee-related earnings in Canada.

•Individual - Protectiondown$8 million: Lower earnings due to the sale of Sun Life UK, and lower net investment results in the U.S., partially offset by business growth reflecting good sales momentum during the past year in Asia.

•Corporate expenses & other$(53) million increase in net loss includes higher debt financing costs.

•Higher expenses across business types were driven by volume growth, continued investments in the business, and higher incentive compensation.

Reported net income of $871 million increased $760 million, driven by favourable market-related impacts primarily reflecting interest rates partially offset by real estate experience, a $170 million charge related to the sale of Sun Life UKand a higher increase in SLC Management's acquisition-related liabilitiesin the prior year, and ACMA impacts; partially offset by fair value changes in management's ownership of MFS shares.

Second Quarter 2023

Underlying net income of $920 millionincreased $112 million or 14%, driven by:

•Wealth & asset management down$1 million: Higher investment income driven by volume growth and an increase in yields was largely offset by lower fee-based earnings in MFS, reflecting equity market declines over the past year, as well as higher expenses in Canada.

•Group - Health & Protection up$122 million: Strong performance driven by good premium growth and better disability experience in Canada and the U.S., as well as a full quarter of DentaQuest contributions.

•Individual - Protectionup$50 million: Higher premiums reflecting good sales momentum during the past year in Asia, and improved insurance experience in Canada and the U.S.

•Corporate expenses & other $(59) million increased net loss driven by higher operating expenses including incentive compensation and an increase in debt financing costs.

•Higher earnings on surplus reflecting an increase in realized gains and net interest income from higher rates.

Reported net income of $660 million decreased $270 million or 29%, driven by market-related impacts primarily reflecting interest rates and real estate investments, the prior year gain on the sale-leaseback of the Wellesley office in the U.S., and fair value changes in management's ownership of MFS shares; partially offset by the increase in underlying net income.

First Quarter 2023

Underlying net income of $895 million increased $175 million or 24%, driven by:

•Wealth & asset managementdown$11 million: Lower fee-based earnings in MFS, Canada, and Asia, reflecting equity market declines, largely offset by an increase in investment income driven by higher volumes and yields.

•Group - Health & Protectionup$180 million: Strong performance including premium growth, improved disability in Canada and the U.S., strong medical stop-loss margins, and improved U.S. mortality. DentaQuest results also contributed to the increase.

•Individual - Protectionup$42 million: Higher premiums reflecting good sales momentum during the past year, and improved mortality in Asia.

•Corporate Support & other$(36) million increased net loss: Higher operating expenses including long-term incentive compensation and IFRS 17 project spend, as well as an increase in debt financing costs.

•Higher investment income reflecting an increase in realized gains from surplus assets and net interest income from higher rates.

Reported net income of $806 million increased $141 million or 21%, driven by the increase in underlying net income and gain on the sale of the sponsored markets business in Canada, partially offset by market-related impacts, and DentaQuest integration and SLC Management acquisition-related costs.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. First Quarter 2024 35

Fourth Quarter 2022(1)

Reported net income of $951 million decreased $127 million or 12%, primarily reflecting unfavourable market-related impacts and DentaQuest integration costs, partially offset by the impact of the Canada Tax Rate Change, fair value changes on MFS' share-based payment awards and ACMA. Prior year reported net income included a gain on the initial public offering ("IPO") of our India asset management joint venture partially offset by an increase to SLC Management's acquisition-related liabilities. Underlying net income of $990 million increased
$92 million or 10%, driven by business growth and experience in protection and health and contribution from the DentaQuest acquisition. This was partially offset by lower wealth and asset management earnings reflecting declines in global equity markets, and a higher effective tax rate compared to prior year.

Third Quarter 2022(1)

Reported net income of $466 million decreased $553 million or 54% from prior year, primarily reflecting unfavourable market-related impacts, a $170 million charge related to the sale of Sun Life UK, less favourable ACMA impacts, and an increase in SLC Management's acquisition-related liabilities, partially offset by fair value changes on MFS' share-based payment awards. Underlying net income of
$949 million increased $47 million or 5%, driven by business growth and experience in protection and health including a strong contribution from the DentaQuest acquisition. This was partially offset by lower fee-based income in wealth and asset management, mainly driven by declines in global equity markets.

Second Quarter 2022(1)

Q2'22 reported net income of $785 million decreased $115 million or 13%, reflecting unfavourable market-related impacts and DentaQuest acquisition costs, partially offset by fair value changes on MFS' share-based payment awards and a gain on the sale-leaseback of our Wellesley office in the U.S. Underlying net income of $892 million was up slightly driven by business growth, new business gains, contribution from the DentaQuest acquisition, and lower incentive compensation expenses. This was largely offset by Asset Management results reflecting a decline in global equity markets driving lower average net assets, lower available-for-sale gains and morbidity experience in the U.S. Foreign exchange translation led to an increase of $16 million and $12 million in reported net income and underlying net income, respectively.

2. Underlying Net Income and Underlying EPS

Underlying net income is a non-IFRS financial measure that assists in understanding Sun Life's business performance by making certain adjustments to IFRS income. Underlying net income, along with common shareholders' net income (Reported net income), is used as a basis for management planning, and is also a key measure in our employee incentive compensation programs. This measure reflects management's view of the underlying business performance of the company and long-term earnings potential. For example, due to the longer term nature of our individual protection businesses, market movements related to interest rates, equity markets and investment properties can have a significant impact on reported net income in the reporting period. However, these impacts are not necessarily realized, and may never be realized, if markets move in the opposite direction in subsequent periods or in the case of interest rates, the fixed income investment is held to maturity.

Underlying net income removes the impact of the following items from reported net income:

•Market-related impacts reflecting the after-tax difference in actual versus expected market movements, including:

i)Net interest impact from risk-free rate, credit spread, and swap spread movements, reflecting accounting mismatches between assets and liabilities:

a.Differences arising from fair value changes(1) of fixed income assets (including derivatives) measured at FVTPL supporting insurance contracts, compared to fair value changes of the liabilities(2);

b.Fair value changes of fixed income assets (including derivatives) measured at FVTPL supporting our investment contract liability and surplus portfolios(3); and

c.Tax-exempt investment income above or below expected long-term tax savings relating to our Canadian multi-national insurance operations.

ii)Non-fixed income investments where the weighted average expected retuis approximately 2% per quarter, including:

a.Equity investments (including derivatives) supporting insurance contracts and surplus portfolios; and

b.Investment properties supporting insurance contracts and surplus portfolios.

•ACMA - captures the impact of method and assumption changes, and management actions on insurance and reinsurance contracts.

•Other adjustments:

i)Management's ownership of MFS shares - this adjustment removes the change in fair value and other activity related to MFS common shares owned by management.

ii)Acquisition, integration, and restructuring - expense and income related to acquisition or disposal of a business. Also includes expenses related to restructuring activities.

iii)Intangible asset amortization - removes the amortization expense associated with finite life intangible assets arising from acquisitions or business combinations excluding amortization of software and distribution agreements.

iv)Other - represents items that are unusual or exceptional in nature which management believes are not representative of the long-term performance of the Company.

Underlying EPS (diluted). This measure is used in comparing the profitability across multiple periods and is calculated by dividing underlying net income by weighted average common shares outstanding for diluted EPS, excluding the dilutive impact of convertible instruments. For additional information about the underlying net income, see above. For additional information about the composition of the EPS, please refer to Note 13 of our Interim Consolidated Financial Statements for the period ended March 31, 2024. For additional information about the SLEECS, please refer to Note 12 of our 2023 Annual Consolidated Financial Statements.

(1)For fixed income assets, Underlying Net Income includes credit experience from rating changes on assets measured at FVTPL, and the ECL impact for assets measured at FVOCI.

(2)Underlying net income is based on observable discount curves and exchange rates at the beginning of the period.

(3)Underlying net income for earnings on surplus includes realized gains (losses) on fixed income assets classified as FVOCI.

(3)Includes integration costs associated with DentaQuest, acquired on June 1, 2022.

(4)To meet regulatory obligations, in Q1'24 we sold 6.3% of our ownership interest in Aditya Birla Sun Life AMC Limited, generating a gain of
$84 million. As a result of the transaction, our ownership interest in ABSLAMC was reduced from 36.5% to 30.2% for gross proceeds of $136 million.

(5)Includes a $65 million gain on the sale of the sponsored markets business in Canada in Q1'23.

(7)On December 27, 2023, Bermuda enacted its Corporate Income Tax Act 2023, which will apply a 15% income tax beginning on January 1, 2025 ("Bermuda Corporate Income Tax Change"). The enacted legislation provides an economic transition adjustment that aligns an entity's starting point for the tax regime more closely with its economic position prior to the application of the Corporate Income Tax 2023. The benefit of this economic transition adjustment has been recognized in 2023. As a result, reported net income increased by $51 million in Q4'23, reflected in Other adjustments.

In contrast, the net income impacts of method and assumption changes in the Interim Consolidated Financial Statements for the period ended March 31, 2024 (Note 10.B.v of the 2023 Annual Consolidated Financial Statements) includes amounts attributable to participating policyholders and excludes non-liability impacts.

Taxes related to underlying net income adjustments may vary from the expected effective tax rate range reflecting the mix of business based on the Company's international operations and other tax-related adjustments.

3. Additional Non-IFRS Financial Measures

Management also uses the following non-IFRS financial measures:

After-tax profit margin for U.S. Group Benefits. This ratio expresses U.S. Group Benefits underlying net income as a percentage of net premiums. It assists in explaining our results from period to period and measures profitability. This ratio is calculated by dividing underlying net income (loss) by net premiums for the trailing four quarters. There is no directly comparable IFRS measure.

Assets under administration (in SLC Management). AUA represents Client assets for which Sun Life provides administrative services. In Asset Management, AUA includes assets distributed by SLC Management's affiliate, Advisors Asset Management, Inc. There is no directly comparable IFRS measure.

Assets under management. AUM is a non-IFRS financial measure that indicates the size of our Company's assets across asset management, wealth, and insurance. There is no standardized financial measure under IFRS. In addition to the most directly comparable IFRS measures, which are the balance of General funds and Segregated funds on our Statements of Financial Position, AUM also includes Third-party AUM and Consolidation adjustments. "Consolidation adjustments" is presented separately as consolidation adjustments apply to all components of total AUM.

AUM not yet earning fees. This measure represents the committed uninvested capital portion of total AUM not currently earning management fees. The amount depends on the specific terms and conditions of each fund. There is no directly comparable IFRS measure.

Capital raising. This measure consists of increases in SLC Management's commitments from fund raising activities for all real estate, infrastructure and alternative credit Clients excluding leverage. Investment-grade fixed income capital raising consists of sales made to new Clients. There is no directly comparable IFRS measure.

Cash and other liquid assets. This measure is comprised of cash, cash equivalents, short-term investments, and publicly traded securities, net of loans related to acquisitions that are held at SLF Inc. (the ultimate parent company), and its wholly owned holding companies. This measure is a key consideration of available funds for capital re-deployment to support business growth.


($ millions)	As at March 31, 2024	As at December 31, 2023

(1)Includes publicly traded bonds.

(2)Includes ETF Investments.

Constant currency. We remove the impacts of foreign exchange translation from certain IFRS and non-IFRS measures to assist in comparing our results from period to period. The impacts of foreign exchange translation is approximated by using the foreign exchange rates in effect during the comparative period, using the average or period end foreign exchange rates, as appropriate.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. First Quarter 2024 41

CSM Movement Analysis includes certain non-IFRS financial measures, detailed below, and also presents certain measures on a net basis to reflect how the business is managed, compared to a gross basis in the Consolidated Financial Statements. Examples include i) The impacts of insurance contracts issued is presented net of reinsurance; ii) Impact of new business is presented net of acquisition expense gain/loss; and iii) Certain methodology changes are presented as an impact of change in assumptions, whereas the Consolidated Financial Statement presentation is a contract modification.

•Organic CSM Movement is comprised of the Impact of new insurance business, Expected movements from asset returns & locked-in rates, Insurance experience gains/losses, and CSM recognized for services provided.

•Impact of new insurance business on CSM, also referred to as "new business CSM", represents growth from sales activity in the period, including individual protection sales (excluding joint ventures), and defined benefit solutions and segregated fund wealth sales in Canada. New business CSM is presented net of acquisition expense gain/loss.

•Expected movements from asset returns & locked-in rates applies to variable fee approach ("VFA") and general measurement approach ("GMA") contracts. For VFA contracts, this component of the CSM movement analysis is comprised of two factors: (i) the expected retuon underlying assets and (ii) the measurement of financial guarantees. The difference between actual and expected results are reported as the impact of markets. For GMA contracts, this component of the CSM includes the accretion of the CSM balance at locked-in rates, which refer to the term structure associated with locked-in discount rates, set when the insurance contract was sold or on transition to IFRS 17. Average locked-in rates increase with the passage of time on in-force business and new business added at current rates.

•Impact of markets & other includes the difference between actual and expected movement for VFA contracts for: (i) the retuon underlying assets and (ii) the measurement of financial guarantees. Also includes other amounts excluded from Organic CSM Movement.

•Insurance experience gains/losses represents the current period impacts of insurance experience, resulting in a change in future cash flows that adjust CSM.

•Impact of change in assumptions represents the future period impacts of changes in fulfilment cash flows that adjust CSM.

•CSM market sensitivities. CSM market sensitivities are non-IFRS financial measures for which there are no directly comparable measures under IFRS so it is not possible to provide a reconciliation of these amounts to the most directly comparable IFRS measures.

Deployment. This measure represents the amount of capital that has been invested in the period, including leverage where applicable. Deployment also includes capital committed in infrastructure deals to be invested in specific assets. There is no directly comparable IFRS measure.

Drivers of Earnings. The Drivers of Earnings ("DOE") analysis provides additional detail on the sources of earnings, primarily for protection and health businesses, and explains the actual results compared to the longer term expectations. The DOE is presented on a reported and underlying common shareholders' basis. Within the net insurance service result, the underlying DOE provides detail on expected insurance earnings, impact of new insurance business and experience gains (losses). Within the net investment result, the underlying DOE provides detail on expected investment earnings, credit experience, earnings on surplus, and joint ventures & other. For more information, refer to the headings "Underlying net income and Underlying EPS", "Earnings on surplus", "Notable items attributable to reported and underlying net income", in this document.

Certain amounts in the DOE are presented on a net basis to reflect how the business is managed, compared to a gross basis in the Consolidated Financial Statements. Examples include: i) Net investment result and Other expenses of the Asset Management operating segment are combined with Fee Income to report the net contribution to earnings; ii) Income for fee-based businesses is reported net of the associated expenses; iii) Carried interest in SLC Management within Fee Income excludes the carried interest that Sun Life does not participate in economically, and nets the non-controlling interest portion of the carried interest against fee income and expenses of consolidated funds; iv) Net investment results include assets returns net of the crediting rate for investment contract liabilities and the unwinding of and changes in the discount rate for insurance contract liabilities; v) Earnings on surplus reflects net spread earned from investment strategies; vi) Earnings attributable to the participating account are excluded; and vii) Assumption changes and management actions combines the amounts included in Net insurance service result and Net investment result.

Earnings on Surplus. This component of the Drivers of Earnings represents the net income earned on a company's surplus funds. Earnings on Surplus is comprised of realized gains on fair value through other comprehensive income assets, as well as net investment returns on surplus, such as investment income, gains (losses) on seed investments and investment properties mark-to-market, and also includes impacts from derivatives, currency and other items.

Experience-related items attributable to reported net income and underlying net income. These notable items attributable to reported net income and underlying net income are components of the Drivers of Earnings represents gains and losses that are due to differences between the actual results during the reporting period and management's estimate of the expected longer-term returns on assets and liabilities (i.e. expected insurance earnings and expected investment earnings) at the start of the reporting period.

Fee earning AUM. FE AUM consists of assets managed by SLC Management, which are beneficially owned by Clients, on which we eamanagement fees for providing investment management, property management or advisory-related services. There is no directly comparable IFRS measure.

Fee-related earnings and Operating income. Fee-related earnings represent profitability of SLC Management's fee-related portfolios, and is calculated as Fee-related revenue less Fee-related expenses. Operating income represents profit realized from our business operations, and is calculated as the sum of Fee-related earnings, Investment income (loss) and performance fees, and Interest and other. Fee-related revenue represents all fee income, with the exception of performance fees, generated from third-party investors. Fee-related expenses represent all expenses directly related to generating fee revenue from third-party investors. Investment income (loss) and performance fees represent total income or loss from our seed investments, net of the related expenses. Interest and other represents performance fee compensation, our net interest income or expense and income from managing the General Account assets.

(4)Investment income (loss) and performance fee in SLC Management's Supplemental Income Statement relates to the underlying results of our seed investments. As such, we have excluded non-underlying market-related impacts as well as the gains or losses of certain non-seed hedges that are reported under Net investment income (loss) under IFRS. The reconciliation is as follows (amounts have been adjusted for rounding):

(5)Includes Interest and other reported under Fee income under IFRS, net of Interest and other reported under Total expenses under IFRS.

Financial leverage ratio. This ratio is an indicator of the Company's balance sheet strength measured by its proportion of capital qualifying debt in accordance with OSFI guidelines. This is calculated as the ratio of total debt plus preferred shares to total capital including the contractual service margin net of taxes, where debt consists of all capital-qualifying debt securities. Capital-qualifying debt securities consist of subordinated debt and innovative capital instruments. The CSM is included net of taxes because debts are repaid and serviced from available after-tax funds.

Impacts of foreign exchange translation. To assist in comparing our results from period-to-period, the favourable or unfavourable impacts of foreign exchange translation are approximated using the foreign exchange rates, in effect during the comparative period, for several IFRS and Non-IFRS financial measures using the average or period end foreign exchange rates, as appropriate. Items impacting a reporting period, such as Revenue, Expenses, and Reported net income (loss) in our Consolidated Statements of Operations, as well as underlying net income (loss), and sales, are translated into Canadian dollars using average exchange rates for the appropriate daily, monthly, or quarterly period. For Assets and Liabilities in our Consolidated Statements of Financial Position, as well as the AUM and certain components of the Drivers of Earnings disclosure, period-end rates are used for currency translation purposes.

LICAT market sensitivities. LICAT market sensitivities are non-IFRS financial measures for which there are no directly comparable measures under IFRS so it is not possible to provide a reconciliation of these amounts to the most directly comparable IFRS measures.

Pre-tax fee related earnings margin. This ratio is a measure of SLC Management's profitability in relation to funds that earecurring fee revenues, while excluding investment income and performance fees. The ratio is calculated by dividing fee-related earnings by fee-related revenues and is based on the last twelve months. There is no directly comparable IFRS measure.

Pre-tax net operating margin. This ratio is a measure of the profitability and there is no directly comparable IFRS measure. For MFS, this ratio is calculated by excluding management's ownership of MFS shares and certain commission expenses that are offsetting. These commission expenses are excluded in order to neutralize the impact these items have on the pre-tax net operating margin and have no impact on the profitability of MFS. For SLC Management, the ratio is calculated by dividing the total operating income by fee-related revenue plus investment Income (loss) and performance fees, and is based on the last twelve months.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. First Quarter 2024 43

The following table provides a reconciliation to calculate MFS' pre-tax net operating margin:


MFS	Quarterly results

(1)Other includes accounting basis differences, such as sub-advisory expenses and product allowances.

(2)Excluding non-controlling interest. For more information on Management's ownership of MFS shares, see the heading Underlying Net Income and Underlying EPS.

Retuon equity.IFRS does not prescribe the calculation of ROE and therefore a comparable measure under IFRS is not available. To determine reported ROE and underlying ROE, respectively, reported net income (loss) and underlying net income (loss) is divided by the total weighted average common shareholders' equity for the period. The ROE provides an indication of the overall profitability of the Company. The quarterly ROE is annualized.

Sales and flows.Asset Management gross flows includes funds from retail and institutional Clients; SLC Management gross flows include capital raising, such as uncalled capital commitments and fund leverage. Asset Management net flows consist of gross flows less gross outflows; SLC Management's net flows do not include Client distributions from the sale of underlying assets in closed-end funds. In Canada and in Asia, net sales consist of wealth sales & asset management gross flows less redemptions. In Canada, wealth sales & asset management gross flows consist of sales in Group Retirement Services and Individual Wealth; group - health & protection sales consist of workplace benefits sold by Sun Life Health; and individual - protection sales refer to individual insurance sales. In the U.S., group - health & protection sales consist of sales by Group Benefits and Dental. In Asia, wealth sales & asset management gross flows consist of Hong Kong wealth sales & asset management gross flows, Philippines mutual fund sales, wealth sales & asset management gross flows by our India and China joint ventures and associates, and Aditya Birla Sun Life AMC Limited's equity and fixed income mutual fund sales based on our proportionate equity interest, including sales as reported by our bank distribution partners; individual - protection sales consist of the individual insurance sales, by our subsidiaries and joint ventures and associates, based on our proportionate equity interest, in the Philippines, Indonesia, India, China, Malaysia, Vietnam, International, Hong Kong and Singapore. Asia also has group - health & protection sales in the Philippines, Hong Kong and our joint ventures. To provide greater comparability across reporting periods, we exclude the impacts of foreign exchange translation from sales and gross flows. There is no directly comparable IFRS measure.

Third-party AUM. Third-party AUM is composed of retail, institutional, and other third party assets, which includes general fund and segregated fund assets managed by our joint ventures. In Asset Management, third-party AUM includes Client assets for retail and institutional Clients, as well as capital raising, such as uncalled commitments and fund leverage in SLC Management. In Canada, third-party AUM includes Client assets in retail mutual fund products of Sun Life Global Investments. In Asia, third-party AUM includes Client assets in Hong Kong managed fund products, International wealth & asset management products, Philippines mutual and managed fund products, Aditya Birla Sun Life AMC Limited equity and fixed income mutual fund products, Sun Life Everbright Asset Management products and our joint ventures' general fund and segregated fund assets based on our proportionate equity interest. There is no directly comparable IFRS financial measure.

Total weighted premium income ("TWPI"). This measure consists of 100% renewal premiums, 100% of first year premiums, and 10% of single premiums. In contrast to sales, which only includes premiums from new business, TWPI includes renewal premiums, reflecting the strength of the in-force block and providing a better understanding of both new and existing business. There is no directly comparable IFRS measure.

Underlying dividend payout ratio. This is the ratio of dividends paid per share to diluted underlying EPS for the period. The ratio is utilized during the medium-term capital budgeting process to inform our planned capital initiatives. We target an underlying dividend payout ratio of between 40% and 50% based on underlying EPS. For more information, see Section J - Capital and Liquidity Management in the 2023 Annual MD&A.

Underlying effective tax rate. This measure is calculated using the pre-tax underlying net income and the income tax expense associated with it. Our statutory tax rate is normally reduced by various tax benefits, such as lower taxes on income subject to tax in foreign jurisdictions, a range of tax-exempt investment income, and other sustainable tax benefits. Our effective tax rate helps in the analysis of the income tax impacts in the period.

(1)2022 results have been restated for the adoption of IFRS 17 and the related IFRS 9 classification overlay ("the new standards"). The restated results may not be fully representative of our future earnings profile, as we were not managing our asset and liability portfolios under the new standards. The majority of the actions taken to re-balance asset portfolios and transition asset-liability management execution to an IFRS 17 basis occurred in Q1'23. Accordingly, analysis based on 2022 comparative results may not necessarily be indicative of future trends, and should be interpreted with this context.

O. Forward-looking Statements

Condensed Notes to the Interim Consolidated Financial Statements

(Unaudited, in millions of Canadian dollars, except for per share amounts and where otherwise stated. All amounts stated in U.S. dollars are in millions.)

1. General Information

Description of Business

Sun Life Financial Inc. ("SLF Inc.") is a publicly traded company domiciled in Canada and is the holding company of Sun Life Assurance Company of Canada ("Sun Life Assurance"). SLF Inc. and its subsidiaries are collectively referred to as "us", "our", "ours", "we", or "the Company".

Our Interim Consolidated Financial Statements have been prepared in accordance with International Accounting Standard ("IAS") 34 Interim Financial Reporting as issued by the International Accounting Standards Board ("IASB"). We have used accounting policies which are consistent with our accounting policies in our 2023 Annual Consolidated Financial Statements, except as updated in Note 2 below. Our Interim Consolidated Financial Statements should be read in conjunction with our 2023 Annual Consolidated Financial Statements, as interim financial statements do not include all the information incorporated in annual consolidated financial statements prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the IASB.

2. Changes in Accounting Policies

Our material accounting policies and future changes in accounting policies that are not yet effective for us are disclosed in Notes 1 and 2 of our 2023 Annual Consolidated Financial Statements.

2.A New and Amended International Financial Reporting Standards Adopted in 2024

In September 2022, the IASB issued amendments to IFRS 16 Leases to add subsequent measurement requirements for sale and leaseback transactions that satisfy the requirements in IFRS 15 Revenue from Contracts with Customers to be accounted for as a sale. The amendments require a seller-lessee to subsequently measure lease liabilities arising from a leaseback in a way that it does not recognize any amount of the gain or loss that relates to the right of use it retains. The adoption of this amendment, effective January 1, 2024, did not have a material impact on our Consolidated Financial Statements.

2.B New and Amended International Financial Reporting Standards to be Adopted in 2025 or Later

In April 2024, the IASB issued IFRS 18 Presentation and Disclosure in Financial Statements ("IFRS 18") which replaces IAS 1 Presentation of Financial Statements. IFRS 18 introduces new requirements on presentation within the statement of profit or loss, disclosure of management-defined performance measures, and principles for aggregation and disaggregation of financial information in the financial statements and the notes. IFRS 18 will be effective for annual reporting periods beginning on or after January 1, 2027. IFRS 18 is to be applied retrospectively. We are currently assessing the impact that IFRS 18 will have on our Consolidated Financial Statements.

3. Disposition

On March 21, 2024, we completed the partial disposition of our investment in Aditya Birla Sun Life AMC Limited ("ABSLAMC"). As a result of the disposition, our ownership interest was reduced by 6.3% and we generated gross proceeds of $136, which included a realized gain of approximately $98 (pre-tax). After the disposition, we retained ownership of the listed entity of 30.2%.

4. Segmented Information

We have five reportable business segments: Canada, United States ("U.S."), Asset Management, Asia, and Corporate. These business segments operate in the financial services industry and reflect our management structure and internal financial reporting. Asset Management includes the results of our MFS Investment Management and SLC Management business units. Corporate includes the results of our United Kingdom ("UK") business unit and our Corporate Support operations, which include run-off reinsurance operations, as well as investment income, expenses, capital and other items not allocated to our other business groups. In the second quarter of 2023, we completed the sale of our UK Business unit and have retained our economic interest in the annuity business via a reinsurance arrangement that is reported under the U.S. reportable segment. Effective the third quarter of 2023, the run-off reinsurance operations is reported under the U.S. reportable segment.

Revenues from our business segments are derived primarily from life and health insurance, investment management and annuities, and mutual funds. Revenues not attributed to the strategic business units are derived primarily from Corporate investments and earnings on capital. Transactions between segments are executed and priced at an arm's-length basis in a manner similar to transactions with third parties.

The expenses in each business segment may include costs or services directly incurred or provided on their behalf at the enterprise level. For other costs not directly attributable to one of our business segments, we use a management reporting framework that uses assumptions, judgments, and methodologies for allocating overhead costs and indirect expenses to our business segments.

Intersegment transactions consist primarily of internal financing agreements which are measured at fair values prevailing when the arrangements are negotiated. Intersegment investment income consists primarily of interest paid by U.S. to Corporate. Intersegment fee income is primarily asset management fees paid by our business segments to Asset Management. SLC Management collects fee income and incurs the operational expenses associated with the management of the general fund assets. Intersegment transactions are eliminated in the Consolidation adjustments column in the following tables.

Management considers its external Clients to be individuals and corporations. We are not reliant on any individual Client as none is individually significant to our operations.

Collateralized Loan Obligations Structure

Crescent, a subsidiary within our Asset Management business segment, issues and manages CLOs. Each CLO is a special purpose vehicle that owns a portfolio of investments, consisting primarily of senior secured loans, and issues various tranches of senior and subordinated notes to third parties for the purpose of financing the purchase of those investments. Assets of the special purpose vehicle, the senior secured loans, are included in Other financial invested assets and the associated liabilities, the senior and subordinated notes issued to third parties, are included in Other liabilities in our Consolidated Statements of Financial Position.

As at March 31, 2024, the carrying value of the assets related to CLOs are $3,784 (December 31, 2023 - $3,478), which consists of cash and accounts receivable of $268 (December 31, 2023 - $251) and loans of $3,516 (December 31, 2023 - $3,227). These underlying loans are mainly below investment grade.

As at March 31, 2024, the carrying value of the liabilities related to CLOs are $3,545 (December 31, 2023 - $3,247). Our maximum contractual exposure to loss related to the CLOs is limited to our investment of $215 (December 31, 2023 - $192) in the most subordinated tranche. The net unrealized loss incurred to date is $41.

5.A.ii Non-Financial Invested Assets

Non-financial invested assets consist of investment properties, investment in associates, subsidiaries and joint ventures which are not consolidated. As at March 31, 2024, the carrying value and fair value of investment properties was $9,555 (December 31, 2023 - $9,723) and $9,555 (December 31, 2023 - $9,723), respectively.

(1) Included in Net investment income (loss) in our Consolidated Statements of Operations for Total invested assets measured at fair value.

(2) Total gains and losses in net income (loss) and other comprehensive income ("OCI") are calculated assuming transfers into or out of Level 3 occur at the beginning of the period. For an asset or liability that transfers into Level 3 during the reporting period, the entire change in fair value for the period is included in the table above. For transfers out of Level 3 during the reporting period, the change in fair value for the period is excluded from the table above.

(3) Investment properties included in net income is comprised of fair value changes on investment properties of $(157) for the three months ended March 31, 2024, (March 31, 2023 - $(11)), net of amortization of leasing commissions and tenant inducements of $9 for the three months ended March 31, 2024, (March 31, 2023 - $6). As at March 31, 2024, we have used assumptions that reflect known changes in the property values including changes in expected future cash flows.

(4) Transfers into Level 3 occur when the inputs used to price the assets and liabilities lack observable market data, and as a result, no longer meet the Level 1 or 2 definitions at the reporting date. Transfers out of Level 3 occur when the pricing inputs become more transparent and satisfy the Level 1 or 2 criteria and are primarily the result of observable market data being available at the reporting date, thus removing the requirement to rely on inputs that lack observability.

(5) Foreign currency translation relates to the foreign exchange impact of translating Level 3 assets and liabilities of foreign subsidiaries from their functional currencies to Canadian dollars.

8. Fee Income


For the three months ended
March 31, 2024	March 31, 2023
Fee income from service contracts:
Distribution fees	$	255	$	232
Fund management and other asset-based fees	1,427	1,365
Administrative service and other fees	330	304
Total fee income	$	2,012	$	1,901

Distribution fees and Fund management and other asset-based fees are primarily earned in the Asset Management segment. Administrative service and other fees are primarily earned in the Canada and U.S. segments. The fee income by business segment is presented in Note 4.

9. Income Taxes

The Company's effective income tax rate is generally lower than our statutory income tax rate of 27.8% due to various tax benefits, such as lower taxes on income subject to tax in foreign jurisdictions and a range of tax-exempt investment income.

Our effective income tax rate for the three months ended March 31, 2024 was 21.8% compared to 16.2% for the three months ended March 31, 2023. The effective income tax rate for the three months ended March 31, 2024 was higher than the effective income tax rate for the three months ended March 31, 2023 primarily due to the impact of lower tax-exempt investment income earned in 2024.

In our Consolidated Statements of Operations, Income tax expense (benefit) has the following components:


For the three months ended
March 31, 2024	March 31, 2023
Current income tax expense (benefit)	$	307	$	300
Deferred income tax expense (benefit)	(46)	(123)
Total income tax expense (benefit)	$	261	$	177

Recent amendments to IAS 12 Income Taxes provide a mandatory temporary exception to the recognition and disclosure of information about deferred taxes arising from Pillar Two, and we have applied this temporary exception. Our deferred taxes will not reflect impacts of Pillar Two while the mandatory exception is applicable. The global minimum tax rules apply to Sun Life effective January 1, 2024 and have been substantively enacted in several jurisdictions in which Sun Life operates, including the UK, Ireland, Luxembourg and Vietnam, however the rules are not yet substantively enacted in Canada. The Current income tax expense (benefit) for the three months ended March 31, 2024 includes tax expense related to Pillar Two income taxes of $2.

10. Capital Management

10.A Capital

Our capital base is structured to exceed minimum regulatory and internal capital targets and maintain strong credit and financial strength ratings, while maintaining a capital efficient structure. We strive to achieve an optimal capital structure by balancing the use of debt and equity financing. Capital is managed both on a consolidated basis under the principles that consider all the risks associated with the business, as well as at the business group level under the principles appropriate to the jurisdiction in which each operates. We manage the capital for all of our international subsidiaries on a local statutory basis in a manner commensurate with their individual risk profiles. Further details on our capital, and how it is managed, are included in Note 20 of our 2023 Annual Consolidated Financial Statements.

SLF Inc. is a non-operating insurance company and is subject to the Life Insurance Capital Adequacy Test ("LICAT") guideline. As at March 31, 2024, SLF Inc.'s LICAT ratio exceeded the regulatory minimum target as set out by the Office of the Superintendent of Financial Institutions, Canada ("OSFI").

Sun Life Assurance, SLF Inc.'s principal operating life insurance subsidiary in Canada, is also subject to the LICAT guideline. As at March 31, 2024, Sun Life Assurance's LICAT ratio exceeded OSFI's minimum regulatory target; as well as OSFI's supervisory target applicable to operating life insurance companies.

In the U.S., Sun Life Assurance operates through a branch which is subject to U.S. regulatory supervision and it exceeded the levels under which regulatory action would be required as at March 31, 2024. In addition, other subsidiaries of SLF Inc. that must comply with local capital or solvency requirements in the jurisdiction in which they operate maintained capital levels above minimum local requirements as at March 31, 2024.

Our capital base consists mainly of common shareholders' equity, preferred shareholders' equity, equity in the participating account, non-controlling interest's equity, CSM, and certain other capital securities that qualify as regulatory capital.

On August 29, 2023, we launched a normal course issuer bid (the "NCIB") to purchase up to 17 million of our common shares between

August 29, 2023 and, at the latest, August 28, 2024. We implemented an automatic repurchase plan with our designated broker in order to

facilitate purchases of common shares under the NCIB. Under the automatic repurchase plan, our designated broker is able to purchase

common shares pursuant to the NCIB at times when we ordinarily would not be active in the market due to applicable securities laws or
self-imposed blackout periods. Any common shares purchased by us pursuant to the NCIB will be cancelled or used in connection with certain

equity settled incentive arrangements.

For the three months ended March 31, 2024, we purchased and cancelled approximately 2.4 million common shares at an average price per share of $73.34 for a total amount of $174 under the NCIB. The total amount paid to purchase the shares pursuant to the NCIB is allocated to Common shares and Retained earnings in our Consolidated Statements of Changes in Equity. The amount allocated to Common shares is based on the average cost per common share and amounts paid above the average cost are allocated to Retained earnings.

15. Legal and Regulatory Proceedings

We are regularly involved in legal actions, both as a defendant and as a plaintiff. Legal actions naming us as a defendant ordinarily involve our activities as a provider of insurance protection and wealth management products, as an investor and investment advisor, and as an employer. In addition, government and regulatory bodies in Canada, the U.S., the UK, and Asia, including federal, provincial, and state securities and insurance regulators, tax authorities, and other government authorities, from time to time, make inquiries and require the production of information or conduct examinations or investigations concerning our compliance with tax, insurance, securities, and other laws.

Provisions for legal proceedings related to insurance contracts, such as for disability and life insurance claims and the cost of litigation, are included in Insurance contract liabilities in our Consolidated Statements of Financial Position. Other provisions are established outside of the Insurance contract liabilities if, in the opinion of management, it is both probable that a payment will be required and a reliable estimate can be made of the amount of the obligation. Management reviews the status of all proceedings on an ongoing basis and exercises judgment in resolving them in such manner as management believes to be in our best interest.

Our significant legal proceedings and regulatory matters are disclosed in Note 22.G of our 2023 Annual Consolidated Financial Statements. There have been no significant updates to such legal and regulatory proceedings.
