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 net realized investment gains and losses and certain other items as specified in the following pages. 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.

The adjustment related to unrealized investment gains and losses reflects the changes that would be necessary to policyholder liabilities if the unrealized investment gains and losses related to the corresponding available-for-sale securities had been realized. Changes in this adjustment are primarily due to movements in the U.S. Treasury rates and credit spreads.

2018 Significant Items

• During the second quarter of 2018, we accelerated our work on our long-term care annual reserve analysis, which is now anticipated to be completed in the third quarter of 2018. When completed, this work will incorporate our most recent experience and will include a review of all assumptions. The review will also utilize internal and external data and an outside consulting firm for quality assurance and industry benchmarking. Subject to completion of the work, we believe that we may need to increase our reserves for long-term care as part of our third quarter 2018 closing process. Although we still have work to complete and are still assessing our assumptions, we currently expect that any strengthening will likely be predominantly a GAAP event and will likely not exceed $750 million after-tax.

• In January of 2018, we entered into a definitive agreement to acquire Pramerica Zycie TUiR SA ("Pramerica"), a financial protection benefits provider in Poland. The acquisition of Pramerica will expand our European presence, which we believe to be an attractive market for financial protection benefits. The transaction, which we anticipate will close by the end of 2018 subject to customary approvals and closing conditions, is not expected to materially impact our results of operations or financial position for 2018 or alter our share repurchase and common stock dividend strategy.

• In January 2016, the Financial Accounting Standards Board (FASB) issued an update that changed the accounting and disclosure requirements for certain financial instruments. These changes include a requirement to measure equity investments, other than those that result in consolidation or are accounted for under the equity method, at fair value through net income unless the investment qualifies for certain practicability exceptions. In addition, the update clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale fixed maturity securities. We adopted this update effective January 1, 2018 using a modified retrospective approach through a cumulative-effect adjustment as of January 1, 2018 which resulted in a decrease to accumulated other comprehensive income (AOCI) of $17.5 million, an increase to retained earnings of $14.5 million, a decrease to other long-term investments of $3.8 million, and a decrease to deferred income tax liability of $0.8 million.

2017 Significant Items

• Fourth quarter of 2017 unclaimed death benefit reserve increase of $18.5 million for Unum US group life, $8.1 million for Unum US voluntary life and $12.4

million for Colonial Life voluntary life, for a total reserve increase of $39.0 million before tax and $25.4 million after tax.

• Fourth quarter of 2017 net tax benefit of $31.5 million resulting from H.R.1, An Act to Provide Reconciliation Pursuant to Titles II and V of the Concurrent

Resolution on the Budget for Fiscal Year 2018, more commonly known as the Tax Cuts and Jobs Act (TCJA) enacted on December 22, 2017. This is comprised of

a tax benefit of $97.9 million related to the revaluation of our net deferred tax liabilities associated with our U.S. operations to the newly enacted U.S. corporate tax

rate and a tax expense of $66.4 million resulting from the tax on undistributed and previously untaxed foreign earnings and profits.

• Fourth quarter of 2017 results for the Unum US individual disability product line reflects a reserve release of $19.5 million before tax and $12.7 million after tax,

resulting from our annual review of reserve adequacy which reflects the recognition of updated morbidity assumptions in our disabled life reserves.

• First quarter of 2017 loss from a guaranty fund assessment of $20.6 million before tax and $13.4 million after tax.

2016 Significant Item

• In August 2016, we acquired 100 percent of the shares and voting interests in H&J Capital, L.L.C., parent of Starmount Life Insurance Company and AlwaysCare Benefits (which collectively we refer to as Starmount) for a total cash purchase price of $140.3 million, plus contingent cash consideration of $10.0 million. Starmount Life Insurance Company is an independent provider of dental and vision insurance in the U.S. workplace, and AlwaysCare Benefits is a nationally licensed, third-party administrator. Starmount's dental and vision products and new dental and vision products marketed by Unum US are reported in our Unum US segment within our supplemental and voluntary product lines. Colonial Life dental and vision products were introduced in 2018 and are reported in our Accident, Sickness and Disability product line. This acquisition, the results of which are included in our consolidated financial statements for the period subsequent to the date of acquisition, did not have a material impact on revenue, operating results, or sales during 2016.

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 realized investment gains or losses;

• After-tax adjusted operating income or loss, which excludes realized investment gains or losses and 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 and net gain on hedges;

• Leverage ratio, which excludes the unrealized gain or loss on securities and net gain on hedges, and the non-recourse debt and associated capital of Northwind Holdings, LLC;

• Book value per common share, which is calculated excluding AOCI; and

• Benefit ratio for our Unum US individual disability product, adjusted for the reserve release in the fourth quarter of 2017.

Realized investment gains or losses and unrealized gains or losses on securities and net gains on hedges 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. We also 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 the comparable GAAP measures in the determination of overall profitability.

Information reconciling the Company’s outlook on after-tax adjusted operating income growth per share to the comparable GAAP financial measure is not provided. The only amounts excluded from after-tax adjusted operating income are those described in this Appendix to Statistical Supplement, which includes any impact from the long-term care annual reserve analysis that is anticipated to be complete in the third quarter of 2018. The Company is unable to predict with reasonable certainty realized investment gains and losses, which are affected by overall market conditions and also by factors such as an economic or political change in the country of the issuer, a regulatory change pertaining to the issuer’s industry, a significant improvement or deterioration in the cash flows of the issuer, unforeseen accounting irregularities or fraud committed by an issuer, movement in credit spreads, ratings upgrades or downgrades, a change in the issuer’s marketplace or business prospects, or any other event that significantly affects the issuers of the fixed maturity securities which the Company holds in its investment portfolio. 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 16.2, other than book value per common share, which is presented on page 2.
