Reported net margin was approximately 10.4% of revenue, compared with approximately 11.7% in 2022. The consolidated benefit ratio improved to 72.2% from 72.7%; excluding reserve assumption updates and non-contemporaneous reinsurance, it improved to 70.1% from 74.9%.
- Segment performance: Unum US adjusted operating income increased to $1,355.5 million from $972.6 million, with a benefit ratio of 59.8% versus 66.3%. Unum International increased to $158.1 million from $134.0 million. Colonial Life declined to $400.1 million from $412.9 million. Closed Block declined to $164.9 million from $251.9 million.
- Reserve and policy liabilities: Liability for future policy benefits was $40.0 billion, up from $38.6 billion. Long-term care represented $16.6 billion of the liability and was the filing’s critical audit matter.
- Investments: Fixed maturity securities were $36.8 billion at fair value. The net unrealized loss on fixed maturity securities was $1.6 billion, improved from $3.0 billion in 2022. The earned book yield declined to 4.45% from 4.57%.
- Debt: Long-term debt was $3.43 billion, including a $350.0 million variable-rate term loan due in 2027. Contractual principal maturities include $275.0 million in 2025, $350.0 million in 2027 and $354.3 million in 2028, with $2.48 billion thereafter.
- Liquidity and capital: Holding-company liquidity was $1.65 billion. No borrowings were outstanding under the $500.0 million revolving credit facility at year-end, and approximately $935.3 million of additional FHLB borrowing capacity was available. The weighted-average RBC ratio for traditional U.S. insurance subsidiaries was approximately 415%.
- Capital returns: The company repurchased 5.7 million shares for approximately $250.0 million, excluding commissions and excise tax, and paid $277.1 million of common dividends. The quarterly dividend increased to $0.365 per share in the fourth quarter from $0.330 in the fourth quarter of 2022. A new $500.0 million repurchase authorization became effective January 1, 2024.
Material Changes Versus the Prior Comparable Period
- Premium income and sales grew across the principal operating segments, led by Unum US sales growth of 15.1% and Unum International sales growth of 27.8%.
- Underlying operating performance improved materially, particularly in Unum US, due to favorable disability claims experience, higher premium income and improved benefit ratios.
- GAAP net income declined despite stronger adjusted operating income because 2023 included a $177.2 million pretax net reserve increase from assumption updates, compared with a $243.3 million pretax net reserve benefit in 2022.
- The largest adverse reserve update was a $368.1 million pretax increase in Closed Block long-term care reserves, driven primarily by lower expected active-policy lapse and mortality rates, partially offset by higher expected future premium rate increases.
- Unum US group disability reserves benefited from a $121.0 million pretax reduction related primarily to sustained improvement in claim recovery trends. Colonial Life benefited from an $80.7 million reduction related primarily to improved claim-cost assumptions and higher policyholder lapses.
- Closed Block long-term care performance deteriorated: the net premium ratio increased to 93.5% from 85.1%, and the interest-adjusted loss ratio increased to 97.9% from 84.0%, excluding reserve assumption updates.
- Operating cash flow decreased by $215.9 million, while investing cash outflows narrowed to $725.9 million from $955.9 million. The company sold more than $700 million of shorter-duration long-term care bonds and reinvested the proceeds in higher-quality, higher-yielding, longer-duration assets, recognizing approximately $35 million of investment losses.
- Other comprehensive income was $140.3 million, compared with $1.72 billion in 2022, primarily reflecting less favorable changes in investment values and insurance liability discount-rate effects than in 2022.
- The company adopted ASU 2018-12 using a modified retrospective approach. Prior-period amounts were recast, and the adoption materially changed reserve, deferred acquisition cost, other comprehensive income and equity presentation.
Guidance, Outlook, Risks and Unusual Items
Management expects positive operating trends to continue in 2024. It expects continued premium and sales growth, stable or favorable claims experience in the core businesses, strong adjusted operating income in Unum US and Colonial Life, and continued growth in Unum International. Management did not provide a consolidated numerical earnings target in the provided filing text.
- Higher interest rates may increase yields on new investments but may create additional unrealized losses on existing holdings. Lower rates could reduce unrealized losses but pressure future investment yields.
- Unum International expects sales and premium growth but noted that 2023 earnings benefited from inflation-linked income, which is expected to decline in 2024.
- Closed Block premium income and adjusted operating revenue are expected to decline over the long term as legacy blocks run off. Long-term care remains subject to claims volatility and the regulatory approval process for premium-rate increases.
- The Maine Bureau of Insurance reserve deficiency for Unum America’s long-term care business was fully recognized under the permitted statutory phase-in basis as of December 31, 2023. The company made $600.0 million of capital contributions to affiliated captive reinsurer Fairwind during 2023 and does not expect to make contributions in 2024.
- Key risks include long-term care morbidity, mortality, lapse and claim-resolution assumptions; disability incidence and recovery trends; interest-rate, credit-spread and investment-default risk; commercial real estate exposure; reinsurance counterparty collectability; regulatory capital and dividend restrictions; litigation; cybersecurity; technology execution; third-party vendors; and foreign-currency translation.
- Unum reported that cybersecurity risks had not materially affected, and were not reasonably likely to materially affect, its strategy, operations or financial condition as of the filing date. The company nevertheless identified cyberattacks, ransomware, privacy breaches and vendor incidents as potentially material risks.
- Ernst & Young issued unqualified opinions on the financial statements and internal control over financial reporting. The critical audit matter was valuation of the $16.6 billion long-term care liability for future policy benefits.
Investor Verification Checklist
- Verify the sustainability of favorable Unum US disability claim recovery trends and the expected 2024 benefit ratios.
- Review long-term care reserve sensitivity to lapse, mortality, morbidity, claim incidence, claim resolution and approved premium-rate increase assumptions.
- Reconcile GAAP net income with after-tax adjusted operating income and assess whether excluded reserve, reinsurance and investment items may recur.
- Assess statutory capital, the 415% RBC ratio, Fairwind’s role, future capital contributions and restrictions on subsidiary dividends.
- Review the $1.6 billion net unrealized fixed-maturity loss, investment-grade versus below-investment-grade exposure, commercial mortgage portfolio and private-equity commitments.
- Confirm debt maturities, variable-rate exposure, credit-facility covenants and the conditions that could trigger the contingent issuance of up to $400 million of senior notes.
- Evaluate operating cash flow conversion, policyholder liability cash requirements and the availability of holding-company liquidity under stressed claims or market conditions.
- Monitor regulatory, litigation, cybersecurity, reinsurance-counterparty and technology risks, including matters for which the filing states that potential losses cannot be reasonably estimated.
