Unum Group Financial Results by Segment

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, non-contemporaneous reinsurance, and reserve assumption updates, 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.

2023 Significant Items

•Third quarter of 2023 reserve assumption updates resulting in a net reserve increase of $177.2 million before tax, or $139.3 million after tax.

•In 2018, the Financial Accounting Standards Board issued ASU 2018-12, "Targeted Improvements to the Accounting for Long-Duration Contracts." This update significantly amended the accounting and disclosure requirements for long-duration insurance contracts. The update was effective for periods beginning January 1, 2023. We adopted this guidance effective January 1, 2023 using the modified retrospective approach with changes applied as of January 1, 2021, also referred to as the transition date.

•We adjusted all prior period operating results, balance sheets, and related metrics throughout this document for the adoption of ASU 2018-12, "Targeted Improvements to the Accounting for Long-Duration Contracts." Additionally, adjusted operating results also reflect the exclusion of reserve assumption updates as discussed in our "Non-GAAP Financial Measures" on page 15.2 for all prior periods with assumption updates.

2022 Significant Items

•Third quarter of 2022 reserve assumption updates resulting in a net reserve reduction of $243.3 million before tax, or $192.1 million after tax.

2021 Significant Items

•Third quarter of 2021 reserve assumption updates resulting in a net reserve reduction of $235.0 million before tax, or $185.9 million after tax.

•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 in operating earnings 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 recognized the following in 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.

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

•Reinsurance recoverable of $1,132.5 million related to the policies on claim status (DLR cohort).

•A reduction to the cost of reinsurance, or prepaid reinsurance premium, of $99.4 million related to the DLR cohort. We amortized $44.1 million or $34.8 million after tax, of the cost of reinsurance in 2023, $50.3 million or $39.7 million after tax in 2022, and $69.8 million or $55.1 million after tax in 2021.

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

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

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, non-contemporaneous reinsurance, and reserve assumption updates, 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.

Cash flow assumptions used to calculate our liability for future policy benefits are reviewed at least annually and updated, as needed, with the resulting impact reflected in net income. While the effects of these assumption updates are recorded in the reporting period in which the review is completed, these updates reflect experience emergence and changes to expectations spanning multiple periods. We believe that by excluding the impact of reserve assumption updates we are providing a more comparable and consistent view of our quarterly results.

We 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. As a result, we exclude the amortization of the cost of reinsurance that we recognized upon the exit of the business related to the policies on claim status as well as the impact of non-contemporaneous reinsurance that resulted from the adoption of ASU 2018-12. Due to the execution of the second phase of the reinsurance transaction occurring after January 1, 2021, the transition date of ASU 2018-12, in accordance with the provisions of the ASU related to non-contemporaneous reinsurance, we were required to establish the ceded reserves using an upper-medium grade fixed-income instrument as of the reinsurance transaction date in March 2021 which resulted in higher ceded reserves compared to that which was reported historically. However, the direct reserves for the block reinsured in the second phase were calculated using the original discount rate utilized as of the transition date. Both the direct and ceded reserves are then remeasured at each reporting period using a current discount rate reflective of an upper-medium grade fixed-income instrument, with the changes recognized in other comprehensive income (loss). While the total equity impact is neutral, the different original discount rates utilized for direct and ceded reserves result in disproportionate earnings impacts. The impact of non-contemporaneous reinsurance will fluctuate depending on the magnitude of reserve changes during the period. We believe that the exclusion of these items provides a better view of our results from our ongoing businesses.

15.2

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 15.4, other than book value per common share, which is presented on page 2.

Due to the implementation of ASU 2018-12 for which the beginning balances 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 balance at January 1, 2021. As a result, average equity for the year ended December 31, 2021 for certain of our segments will not compute using the historical allocated equity at December 31, 2020.
