Item 7.01 Regulation FD Disclosure

The following information is being furnished under Item 7.01 - Regulation FD
Disclosure. Such information, including the exhibits attached hereto, shall not
be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of
1934, as amended, or otherwise subject to the liability of that section.

On March 28, 2022, The Hanover Insurance Group, Inc. (the "Company") published
select historical quarterly and annual financial information reflecting the
planned changes to the Company's segment reporting. As publicly announced during
the Company's fourth quarter earnings call on February 3, 2022, the Company
plans to change its segment reporting, beginning with the quarterly financial
information to be released for the first quarter ending March 31, 2022, to
disaggregate the former Commercial Lines segment into Core Commercial and
Specialty segments, including expenses, allocated net investment income, and
other income and expenses for each. Additionally, the Company will expand its
reporting of top-line measures to include line of business and sub-segment net
premiums written, renewal price change, retention, and other such measures.
Concurrently, the Company will no longer report supplemental loss ratio
information by product line for its Core Commercial segment. Finally, although
the Company's Personal Lines segment definition did not change, in order to
streamline reporting and better align with industry practice, its homeowners
sub-segment will be combined with other personal lines, which is primarily
comprised of the Company's personal umbrella product. A copy of the select
historical financial information for 2019 through 2021 to reflect the changes
discussed above is furnished as Exhibit 99.2 to this Current Report on Form 8-K
and is hereby incorporated by reference in this Item 7.01.

The changes in reportable segment structure discussed above, as reflected in the
information included in this Current Report on Form 8-K, do not affect the
Company's previously reported consolidated results of operations, underwriting
ratios, financial condition or cash flows and affects only the presentation of
the segment information previously reported.

A copy of the March 28, 2022, press release discussing both the planned changes
to the Company's segment reporting and the publication of the select historical
quarterly and annual financial information to reflect the changes in segment
reporting is furnished herewith as Exhibit 99.1 to this Current Report on Form
8-K.
