1 We previously reported Policy and Contract Benefits and Reserves for Future Policy Benefits in our consolidated balance sheets for each of the periods shown above. As part of the adoption of ASU 2018-12, these balances were reclassified into new line items, Future Policy Benefits and Policyholders' Account Balances.

4.1

Unum Group Financial Results - Adjusted for ASU 2018-12

We measure and analyze our segment performance on the basis of "adjusted operating revenue" and "adjusted operating income" or "adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of income due to the exclusion of investment gains or losses, amortization of the cost of reinsurance, and non-contemporaneous reinsurance, as well as certain other items as specified in the following pages. Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, and gains or losses on derivatives. These performance measures are in accordance with GAAP guidance for segment reporting, but they should not be viewed as a substitute for total revenue, income before income tax, or net income.

Appendix to Supplemental Exhibit

2022 Significant Items

•Third quarter of 2022 reserve assumption updates resulting in reserve reductions of $121.0 million and $34.0 million before tax, or $95.6 million and $26.9 million after tax, in our Unum US group long-term disability and group life product lines, respectively.

2021 Significant Items

•Third quarter of 2021 reserve assumption updates resulting in a reserve reduction of $215.0 million before tax, or $169.9 million after tax, in our Unum US group long-term disability product line.

•Third quarter of 2021 impairment loss of $12.1 million before tax, or $9.6 million after tax, on previously capitalized internal-use software that we no longer plan to utilize.

•Second quarter of 2021 cost related to the early retirement of debt of $67.3 million before tax, or $53.2 million after tax.

•Second quarter of 2021 impairment loss of $13.9 million, or $11.0 million after tax, on a right-of-use (ROU) asset related to an operating lease for office space that we do not plan to continue using to support our general operations.

•Second quarter of 2021 U.K. tax rate increase from 19 percent to 25 percent, effective April 1, 2023, which resulted in $23.6 million of additional tax expense through continuing operations for the revaluation of our deferred tax assets and liabilities.

•In December 2020, we completed the first phase of a reinsurance transaction, pursuant to which Provident Life and Accident Insurance Company, The Paul Revere Life Insurance Company, and Unum Life Insurance Company of America, wholly-owned domestic insurance subsidiaries of Unum Group, and collectively referred to as "the ceding companies", each entered into separate reinsurance agreements with Commonwealth Annuity and Life Insurance Company (Commonwealth), to reinsure on a coinsurance basis effective as of July 1, 2020, approximately 75 percent of the Closed Block individual disability business, primarily direct business written by the ceding companies. On March 31, 2021, we completed the second phase of the reinsurance transaction, pursuant to which the ceding companies and Commonwealth amended and restated their respective reinsurance agreements to reinsure on a coinsurance and modified coinsurance basis effective as of January 1, 2021, a substantial portion of the remaining Closed Block individual disability business that was not ceded in December 2020, primarily business previously assumed by the ceding companies.

In December 2020, Provident Life and Casualty Insurance Company (PLC), also a wholly-owned domestic insurance subsidiary of Unum Group, entered into an agreement with Commonwealth whereby PLC will provide a 12-year volatility cover to Commonwealth for the active life cohort (ALR cohort). On March 31, 2021, PLC and Commonwealth amended and restated this agreement to incorporate the ALR cohort related to the additional business that was reinsured between the ceding companies and Commonwealth as part of the second phase of the transaction. As part of the amended and restated volatility cover, PLC received a payment from Commonwealth of approximately $18 million.

In connection with the second phase of the reinsurance transaction, Commonwealth paid a total ceding commission to the ceding companies of $18.2 million. The ceding companies transferred assets of $767.0 million, which consisted primarily of cash and fixed maturity securities. In addition, we originally recognized the following in the first quarter of 2021 related to the second phase:

•Net realized investment gains totaling $67.6 million, or $53.4 million after tax, related to the transfer of investments.

•Prior to the implementation of ASU 2018-12, an increase in benefits and change in reserves for future benefits of $133.1 million, or $105.1 million after tax, resulting from the realization of previously unrealized investment gains and losses recorded in accumulated other comprehensive income.

•Transaction costs totaling $6.2 million, or $5.0 million after tax.

•Prior to the implementation of ASU 2018-12, reinsurance recoverable of $990.0 million related to the policies on claim status (DLR cohort).

•Payable of $307.2 million related to the portfolio of invested assets associated with the business ceded on a modified coinsurance basis.

•Prior to the implementation of ASU 2018-12, cost of reinsurance, or prepaid reinsurance premium, of $43.1 million related to the DLR cohort.

Appendix to Supplemental Exhibit - Continued

Deposit asset of $5.0 million related to the ALR cohort.

In applying ASU 2018-12 to the second phase of our Closed Block individual disability reinsurance transaction, we recognized the following changes:

•The ceded reserves were valued using a discount rate reflective of an upper-medium grade fixed-income instrument as of the transaction date and the increase in benefits and change in reserves for future benefits of $133.1 million described above was reversed, resulting in a net $142.5 million decrease to the cost of reinsurance, or prepaid reinsurance premium related to the DLR cohort, and a net $142.5 million increase to the reinsurance recoverable related to the DLR cohort.

Non-GAAP Financial Measures

We analyze our performance using non-GAAP financial measures which exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. We believe the following non-GAAP financial measures are better performance measures and better indicators of the revenue and profitability and underlying trends in our business:

•Consolidated adjusted operating revenue, which excludes investment gains or losses;

•After-tax adjusted operating income or loss, which excludes investment gains or losses, amortization of the cost of reinsurance, and non-contemporaneous reinsurance as well as certain other items, as applicable;

•Adjusted operating return on equity, which is calculated using after-tax adjusted operating income or loss and excludes from equity the unrealized gain or loss on securities, the effect of change in discount rate assumptions on the liability for future policy benefits, and net gain or loss on hedges;

•Leverage ratio, which excludes the unrealized gain or loss on securities, the effect of change in discount rate assumptions on the liability for future policy benefits, and net gain or loss on hedges; and

•Book value per common share, which is calculated excluding accumulated other comprehensive income (loss) (AOCI).

Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, and gains or losses on derivatives. Investment gains or losses and unrealized gains or losses on securities depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our Company. Leverage ratio and book value per common share excluding certain components of AOCI, certain of which tend to fluctuate depending on market conditions and general economic trends, are important measures.

As previously discussed, we have exited a substantial portion of our Closed Block individual disability product line through the two phases of the reinsurance transaction that were executed in December 2020 and March 2021, respectively. As a result, we exclude the amortization of the cost of reinsurance that was recognized upon the exit of the business related to the DLR cohort of policies as well as the impacts related to the non-contemporaneous reinsurance that occurred as a result of the adoption of ASU 2018-12. The impacts of non-contemporaneous reinsurance are related to the second phase of the reinsurance transaction. The direct reserves for this block are locked-in using the discount rate utilized as of the transition date, January 1, 2021, while the ceded reserves are locked-in using an upper-medium grade fixed-income instrument as of the reinsurance transaction date in March 2021, resulting in higher ceded reserves. While the total equity impact is neutral, the different discount rates utilized for direct and ceded reserves result in disproportionate earnings impacts. We believe that the exclusion of these items provides a better view of our results from our ongoing businesses.

We may at other times exclude certain other items from our discussion of financial ratios and metrics in order to enhance the understanding and comparability of our operational performance and the underlying fundamentals, but this exclusion is not an indication that similar items may not recur and does not replace net income or net loss as a measure of our overall profitability.

For a reconciliation of the most directly comparable GAAP measures to these non-GAAP financial measures, refer to the "Reconciliation of Non-GAAP Financial Measures" beginning on page 9.2, other than book value per common share, which is presented on page 2.

1Excludes unrealized gain (loss) on securities, the effect of change in discount rate assumptions on the liability for future policy benefits, and net gain (loss) on hedges and is calculated using the stockholders' equity balances presented on page 9.5. Due to the implementation of ASU 2018-12 for which the beginning balance of 2021 for certain stockholders' equity line items were adjusted, we are computing the average allocated equity for 2021 using internally allocated equity that reflects the adjusted beginning balances at January 1, 2021. As a result, average equity for the years ended December 31, 2021 for certain of our segments will not compute using the historical allocated equity at December 31, 2020.
