CHATTANOOGA, Tenn.(January 30, 2024) - Unum Group (NYSE: UNM) today reported net income of $330.6 million ($1.69 per diluted common share) for the fourth quarter of 2023, compared to net income of $289.2 million ($1.44 per diluted common share) for the fourth quarter of 2022.

Included in net income for the fourth quarter of 2023 is the after-tax amortization of the cost of reinsurance of $8.7 million ($0.04 per diluted common share), the after-tax impact of non-contemporaneous reinsurance of $6.6 million ($0.04 per diluted common share) as well as a net after-tax investment loss on the Company’s investment portfolio of $4.6 million ($0.02 per diluted common share). Included in net income for the fourth quarter of 2022 is the after-tax amortization of the cost of reinsurance of $9.3 million ($0.04 per diluted common share), the after-tax impact of non-contemporaneous reinsurance of $8.1 million ($0.04 per diluted common share), as well as a net after-tax investment gain on the Company’s investment portfolio of $4.9 million ($0.02 per diluted common share).

Effective January 1, 2023, the Company adopted Accounting Standards Update 2018-12 (ASU 2018-12) which amended the accounting and disclosure requirements for long-duration insurance contracts, with changes applied as of January 1, 2021. All prior period operating results and related metrics throughout this document have been adjusted for the impacts of the adoption.

"We closed 2023 with a solid fourth quarter and delivered another year of very strong performance in which we grew adjusted EPS by 23%, reflecting the fundamental strength of our business,” said Richard P. McKenney, president and chief executive officer. “By executing our growth strategy throughout the year, we achieved robust premium and sales growth while delivering against our capital allocation priorities. This included de-risking our balance sheet, increasing our returns to shareholders, and ending the year with robust capital level above our targets. Looking to 2024, the drivers of demand for our solutions remain strong. We are well positioned for continued premiums and earnings growth, driving free cash flow growth and continued flexibility to pursue our capital allocation priorities, including the return of capital to our shareholders."

RESULTS BY SEGMENT

We measure and analyze our segment performance on the basis of "adjusted operating income" or "adjusted operating loss", which differ from income before income tax as presented in our consolidated statements of income due to the exclusion of investment gains or losses, amortization of cost of reinsurance, and the impact of non-contemporaneous reinsurance. 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 U.S. generally accepted accounting principles (GAAP) guidance for segment reporting, but they should not be viewed as a substitute for income before income tax, net income, or net loss.

The benefit ratio for the fourth quarter of 2023 was 59.5 percent, compared to 65.4 percent in the fourth quarter of 2022, due primarily to favorable recoveries and lower claims incidence in the group long-term disability product line as well as favorable discount rate impacts on new claims.

Net investment income decreased 13.1 percent to $21.9 million in the fourth quarter of 2023, compared to $25.2 million in the fourth quarter of 2022, due primarily to a lower level of invested assets, partially offset by higher miscellaneous investment income. The benefit ratio in the fourth quarter of 2023 was 69.5 percent, compared to 78.2 percent in the fourth quarter of 2022, due primarily to lower incidence for waiver of premium benefits. Sales of group life and accidental death and dismemberment products increased 60.7 percent in the fourth quarter of 2023 to $152.5 million, compared to $94.9 million in the fourth quarter of 2022.

Net investment income increased 5.3 percent to $58.1 million in the fourth quarter of 2023, compared to $55.2 million in the fourth quarter of 2022, due to an increase in the yield on invested assets, higher miscellaneous investment income, and an increase in the level of invested assets.

percent for the fourth quarter of 2022, due to unfavorable experience in the critical illness product line, partially offset by favorable experience in the disability product line. The benefit ratio for the individual disability product line was 44.4 percent for the fourth quarter of 2023, compared to 48.4 percent for the fourth quarter of 2022, due primarily to lower average claim size, partially offset by lower mortality.

Premium income was £149.1 million in the fourth quarter of 2023, an increase of 12.9 percent from £132.1 million in the fourth quarter of 2022, due to in-force block growth and higher premium as a result of a reinsurance transaction.

Closed Block Segment

The Closed Block segment reported adjusted operating income of $21.3 million in the fourth quarter of 2023, which excludes the amortization of cost of reinsurance of $11.0 million and the impact of non-contemporaneous reinsurance of $8.4 million related to the Closed Block individual disability reinsurance transaction, compared to $44.3 million in the fourth quarter of 2022, which excludes the amortization of cost of reinsurance of $11.8 million and the impact of non-contemporaneous reinsurance of $10.3 million related to the Closed Block individual disability reinsurance transaction. Premium income for this segment is largely driven by our long-term care product line, and in the fourth quarter of 2023, premium income for long-term care was generally consistent with the same period of 2022. Net investment income increased 6.9 percent to $270.3 million in the fourth quarter of 2023, compared to $252.9 million in the fourth quarter of 2022, due primarily to an increase in the level of invested assets and higher miscellaneous investment income, primarily related to larger increases in the net asset value on our private equity partnerships.

The net premium ratio for the long-term care line of business increased to 93.5 percent in the fourth quarter of 2023, compared to 85.1 percent in the fourth quarter of 2022, driven primarily by the impact of the reserve assumption updates in the third quarter of 2023 and higher claim incidence. Compared to the third quarter of 2023, the net premium ratio increased from 93.4 percent, and overall claims experience was relatively consistent.

Corporate Segment

The Corporate segment reported an adjusted operating loss of $36.5 million in the fourth quarter of 2023, compared to an adjusted operating loss of $37.5 million in the fourth quarter of 2022, due primarily to an increase in net investment income, which was driven by an increase in yield on invested assets, partially offset by higher pension expenses.

Effective tax rate on adjusted operating earnings was 22.8 percent in the fourth quarter of 2023, and 21.7 percent for full year 2023. Long-term adjusted effective tax rate expected to be between 21.5 percent to 22.0 percent.

Outlook

Full-year 2024 outlook of an increase in after-tax adjusted operating income per share of seven percent to nine percent when comparing full-year 2023.

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:

• 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;

•Book value per common share, which is calculated excluding 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 segments.  Book value per common share excluding AOCI provides a more comparable and consistent view of our results, as AOCI tends to fluctuate depending on market conditions and general economic trends.

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.

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.
