Appendix to Statistical Supplement	16
Effective December 31, 2017, to more clearly differentiate between the GAAP and non-GAAP financial measures, we changed the naming convention for our non-GAAP financial measures from “operating” measures to “adjusted operating” measures, which includes a change from "operating revenue" to "adjusted operating revenue", "after-tax operating income" to "after-tax adjusted operating income", and "operating return on equity" to "adjusted operating return on equity". The definition of these labels remains unchanged.
See "Appendix to Statistical Supplement" on page 16 for a summary of significant items and page 16.1 for a reconciliation of our non-GAAP financial measures.

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. Effective December 31, 2017, we changed the naming convention of "operating revenue" to "adjusted operating revenue" and "operating income" to "adjusted operating income" or "adjusted operating loss." The definition of these labels remains unchanged.  We previously excluded the amortization of prior period actuarial gains or losses, a component of the net periodic benefit cost for our pension and other postretirement benefit plans. Effective January 1, 2017, the amortization of prior period actuarial gains or losses is now reported in our Corporate segment as a component of "benefits and expenses" and the tax thereon is reported in "income tax" in the following charts.  Amounts for periods prior to January 1, 2017 have been adjusted to conform to current year reporting.

Amounts for periods prior to January 1, 2017 have been adjusted to conform to current year reporting.

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.

Appendix to Statistical Supplement

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 will be introduced in 2018. 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.

2015 Significant Item

• In September 2015, we acquired 100 percent of the common shares and voting interests in National Dental Plan Limited and associated companies (National Dental) for a total cash purchase price of £35.9 million or $54.3 million. National Dental, a provider of dental insurance in the U.K. workplace, is reported in our Unum UK segment as part of our supplemental 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 or results of operations during 2015.

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 cash flow hedges;

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

• Book value per common share, which is calculated excluding accumulated other comprehensive income (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 cash flow 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. 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.
