1. Nature of Operations and Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Principal Financial Group, Inc. (“PFG”) have been prepared in conformity with accounting principles generally accepted in the U.S. (“U.S. GAAP”) for interim financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.

Operating results for the three months ended March 31, 2025, are not necessarily indicative of the results that may be expected for the year ended December 31, 2025, especially when considering risks and uncertainties that may impact our business, results of operations, financial condition and liquidity. Our use of estimates and assumptions affect amounts reported and disclosed and includes, but is not limited to, the fair value of investments in the absence of quoted market values, investment impairments and valuation allowances, the fair value of derivatives, the fair value of market risk benefits (“MRBs”), measurement of goodwill and intangible assets, the liability for future policy benefits and claims, the value of pension and other postretirement benefit obligations and accounting for income taxes and the valuation of deferred tax assets. Our estimates and assumptions could change in the future. Our results of operations and financial condition may also be impacted by other uncertainties including evolving regulatory, legislative and standard-setter accounting interpretations and guidance.

These interim unaudited condensed consolidated financial statements should be read in conjunction with our annual audited financial statements as of December 31, 2024, included in our Form 10-K for the year ended December 31, 2024, filed with the United States Securities and Exchange Commission (“SEC”). The accompanying condensed consolidated statement of financial position as of December 31, 2024, has been derived from the audited consolidated statement of financial position but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

Consolidation

We have relationships with various special purpose entities and other legal entities that must be evaluated to determine if the entities meet the criteria of a variable interest entity (“VIE”) or a voting interest entity (“VOE”). This assessment is performed by reviewing contractual, ownership and other rights, including involvement of related parties, and requires use of judgment. First, we determine if we hold a variable interest in an entity by assessing if we have the right to receive expected losses and expected residual returns of the entity. If we hold a variable interest, then the entity is assessed to determine if it is a VIE. An entity is a VIE if the equity at risk is not sufficient to support its activities, if the equity holders lack a controlling financial interest or if the entity is structured with non-substantive voting rights. In addition to the previous criteria, if the entity is a limited partnership or similar entity, it is a VIE if the limited partners do not have the power to direct the entity’s most significant activities through substantive kick-out rights or participating rights. A VIE is evaluated to determine the primary beneficiary. The primary beneficiary of a VIE is the enterprise with (1) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and (2) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. When we are the primary beneficiary, we are required to consolidate the entity in our financial statements. We reassess our involvement with VIEs on a quarterly basis. For further information about VIEs, refer to Note 3, Variable Interest Entities.

If an entity is not a VIE, it is considered a VOE. VOEs are generally consolidated if we own a greater than 50% voting interest. If we determine our involvement in an entity no longer meets the requirements for consolidation under either the VIE or VOE models, the entity is deconsolidated. Entities in which we have management influence over the operating and financing decisions but are not required to consolidate, other than investments accounted for at fair value under the fair value option, are reported using the equity method.

Recent Accounting Pronouncements

Description | Date of adoption | Effect on our consolidated financial statements or other significant matters
--- | --- | ---
Standards not yet adopted: | ​ | ​
Disaggregation of income statement expenses This authoritative guidance expands the disclosures about a public entity’s expenses and addresses requests for more granular information about the types of expenses in commonly presented expense categories. | December 31, 2027 | We are currently evaluating the impact this guidance will have on our notes to the consolidated financial statements.
Standards adopted: | ​ | ​
Improvements to income tax disclosures This authoritative guidance provides improvements to income tax disclosures for annual periods primarily related to the rate reconciliation and income taxes paid information. | January 1, 2025 | This guidance will not have a material impact on our notes to the consolidated financial statements when the new annual disclosures are included in our notes to the consolidated financial statements.
Improvements to reportable segments disclosures This authoritative guidance enhances the disclosures about a public entity’s reportable segments and addresses requests from investors for additional, more detailed information about a reportable segment’s expenses. | December 31, 2024 | The enhanced disclosures can be found in Note 18, Segment Information.
Facilitation of the effects of reference rate reform on financial reporting This authoritative guidance provided optional expedients and exceptions for contracts and hedging relationships affected by reference rate reform. An entity could elect not to apply certain modification accounting requirements to contracts affected by reference rate reform and instead account for the modified contract as a continuation of the existing contract. Also, an entity could apply optional expedients to continue hedge accounting for hedging relationships in which the critical terms changed due to reference rate reform. This guidance eased the financial reporting impacts of reference rate reform on contracts and hedging relationships and was effective until December 31, 2022. A subsequent amendment issued in December 2022 extended the relief date from December 31, 2022, to December 31, 2024, and was effective upon issuance. | March 12, 2020 | We adopted the guidance upon issuance prospectively and elected the applicable optional expedients and exceptions for contracts and hedging relationships impacted by reference rate reform through December 31, 2024. The guidance did not have an impact on our consolidated financial statements upon adoption.

​

When we adopt new accounting standards, we have a process in place to perform a thorough review of the pronouncement, identify the financial statement and system impacts and create an implementation plan among our impacted business units to ensure we are compliant with the pronouncement on the date of adoption. This includes having effective processes and controls in place to support the reported amounts. Each of the standards listed above is in varying stages in our implementation process based on its issuance and adoption dates. We are on track to implement guidance by the respective effective dates.

Long-Duration Insurance Contracts Disclosures

​

We include disaggregated rollforwards for deferred acquisition costs (“DAC”), the unearned revenue liability, separate account liabilities, policyholder account balances, the liability for future policy benefits, the additional liability for certain benefit features and MRBs. Further, for certain actuarial balances, disclosures are required for the significant inputs, judgments, assumptions and methods used in measurement, including changes in those inputs, judgments and assumptions, and the effect of those changes on measurement.

​

Amounts from different reportable segments cannot be aggregated for disclosures. Factors to consider in determining the level of aggregation for disclosures include the type of coverage, geography and market or type of customer. We have identified the following levels of aggregation for long-duration insurance contract disclosures.

| o | Investment only – Primarily guaranteed investment contracts (“GICs”) and funding agreements offered to retirement plan sponsors and other institutions

| ● | Principal Asset Management – International Pension

| o | Latin America:

| ◾ | Individual fixed income annuities – SPIAs offered to individuals

| ● | Benefits and Protection – Specialty Benefits:

| o | Individual disability – Disability insurance providing protection to individuals and/or business owners

| ● | Benefits and Protection – Life Insurance:

| o | Universal life – Universal life, variable universal life and indexed universal life insurance products offered to individuals and/or business owners, which will be collectively referred to hereafter as “universal life” contracts; includes our exited universal life insurance with secondary guarantee (“ULSG”) business

| o | Term life – Term life insurance products offered to individuals and/or business owners

2. Other Intangible Assets

Finite Lived Intangible Assets

On January 16, 2025, we announced the signing of an agreement with Bank Consortium Trust Company (“BCT”) to expand our investment management capabilities and exit our sponsor and trustee (pension) roles in Hong Kong for Mandatory Provident Fund Schemes (“MPF Schemes”). BCT will be assuming the role as sponsor and trustee for the Principal MPF Schemes. The transaction is expected to close during the first quarter of 2026, subject to regulatory approval; however, certain transaction impacts were recognized in first quarter 2025. We impaired our distribution agreement intangible asset that will cease to exist, resulting in a $20.0 million loss reported in operating expenses on our consolidated statements of operations. Additionally, our customer relationship intangible asset was classified as held-for-sale, resulting in a $77.0 million loss reported in net realized capital gains (losses) on our consolidated statements of operations. We also recorded an impairment for contract costs from pension contracts. See Note 19, Revenues from Contract with Customers, for further details.

​

3. Variable Interest Entities

We have relationships with various types of entities which may be VIEs. Certain VIEs are consolidated in our financial results. See Note 1, Nature of Operations and Significant Accounting Policies, under the caption “Consolidation” for further details of our consolidation accounting policies. We did not provide financial or other support to investees designated as VIEs for the periods ended March 31, 2025 and December 31, 2024.

Consolidated Variable Interest Entities

Mandatory Retirement Savings Funds

We hold an equity interest in Chilean mandatory privatized social security funds in which we provide asset management services. We determined the mandatory privatized social security funds, which also include contributions for voluntary pension savings, voluntary non-pension savings and compensation savings accounts, are VIEs. This is because the equity holders as a group lack the power, due to voting rights or similar rights, to direct the activities of the entity that most significantly impact the entity’s economic performance and also because equity investors are protected from below-average market investment returns relative to the industry’s return, due to a regulatory guarantee that we provide. Further, we concluded we are the primary beneficiary through our power to make decisions and our significant variable interest in the funds. The purpose of the funds, which reside in legally segregated entities, is to provide long-term retirement savings. The obligation to the customer is directly related to the assets held in the funds and, as such, we present the assets as separate account assets and the obligation as separate account liabilities within our consolidated statements of financial position.

Real Estate

We invest in several real estate limited partnerships and limited liability companies. The entities invest in real estate properties. Certain of these entities are VIEs based on the combination of our significant economic interest and related voting rights. We determined we are the primary beneficiary as a result of our power to control the entities through our significant ownership. Due to the nature of these real estate investments, the investment balance will fluctuate as we purchase and sell interests in the entities and as capital expenditures are made to improve the underlying real estate.

Sponsored Investment Funds

We sponsor and invest in certain investment funds for which we provide asset management services. Although our asset management fee is commensurate with the services provided and consistent with fees for similar services negotiated at arms-length, we have a variable interest for funds where our other interests are more than insignificant. The funds are VIEs as the equity holders lack power through voting rights to direct the activities of the entity that most significantly impact its economic performance. We determined we are the primary beneficiary of the VIEs where our interest in the entity is more than insignificant and we are the asset manager. We deconsolidated a sponsored investment fund in 2025 due to the acquisition of substantial voting rights through investment in the fund by external investors.

Residential Mortgage Loans

We invest in asset-backed securities (“ABS”) trusts. The trusts issue various collateralized mortgage obligation certificates and purchase residential mortgage loans. The trusts are considered VIEs due to insufficient equity to sustain themselves. We concluded we are the primary beneficiary as we purchase substantially all of the certificates and have the obligation to absorb losses that could potentially be significant to the VIEs.

Asset-Backed Limited Partnership

We invest in an ABS limited partnership. The limited partnership issues multiple notes and purchases consumer loans, auto loans, other loans and credit facilities. The limited partnership is considered a VIE due to insufficient equity to sustain itself. We concluded we are the primary beneficiary as we have purchased all of the notes and have the obligation to absorb losses and residual returns that could potentially be significant to the VIE.

​

Assets and Liabilities of Consolidated Variable Interest Entities

The carrying amounts of our consolidated VIE assets, which can only be used to settle obligations of consolidated VIEs, and liabilities of consolidated VIEs for which creditors do not have recourse were as follows:

​

Total | ​ | $ | 37,596.6 | ​ | $ | 34,743.0 | ​ | $ | 35,834.9 | ​ | $ | 33,051.8

(1) | The assets of the mandatory retirement savings funds primarily include separate account assets and equity securities. The liabilities primarily include separate account liabilities.

(2) | The assets of the real estate VIEs primarily include real estate, other investments and cash. Liabilities primarily include other liabilities.

(3) | The assets of sponsored investment funds are primarily fixed maturities and equity securities, certain of which are reported with other investments, and cash. The liabilities primarily include other liabilities. The consolidated statements of financial position included a $298.8 million and $309.9 million redeemable noncontrolling interest for sponsored investment funds as of March 31, 2025 and December 31, 2024, respectively. For certain sponsored investment funds, we have unfunded commitments to the VIE. Unfunded commitments are not liabilities on our consolidated statements of financial position because we are only required to fund additional capital when called upon to do so by the investment manager.

(4) | The assets of the residential mortgage loans VIEs primarily include residential mortgage loans. The liabilities primarily include other liabilities.

(5) | The assets of the asset-backed limited partnership VIE primarily include consumer loans, auto loans, other loans and credit facilities. These assets are reported with cash and cash equivalents, other investments and fixed maturities, trading on the consolidated statements of financial position.

Unconsolidated Variable Interest Entities

We hold a variable interest in a number of VIEs where we are not the primary beneficiary. Our investments in these VIEs are reported in fixed maturities, available-for-sale; fixed maturities, trading; equity securities and other investments in the consolidated statements of financial position and are described below.

Unconsolidated VIEs include certain commercial mortgage-backed securities (“CMBS”), residential mortgage-backed pass-through securities (“RMBS”) and other ABS. All of these entities were deemed VIEs because the equity within these entities is insufficient to sustain them. We determined we are not the primary beneficiary in the entities within these categories of investments. This determination was based primarily on the fact we do not own the class of security that controls the unilateral right to replace the special servicer or equivalent function.

We invest in cash collateralized debt obligations, collateralized bond obligations, collateralized loan obligations and other collateralized structures, which are VIEs due to insufficient equity to sustain the entities. We have determined we are not the primary beneficiary of these entities primarily because we do not control the economic performance of the entities and were not involved with the design of the entities or because we do not have a potentially significant variable interest in the entities for which we are the asset manager.

We have invested in various VIE trusts and similar entities as a debt holder. Most of these entities are classified as VIEs due to insufficient equity to sustain them. In addition, we have an entity classified as a VIE based on the combination of our significant economic interest and lack of voting rights. We have determined we are not the primary beneficiary primarily because we do not control the economic performance of the entities and were not involved with the design of the entities.

We have invested in partnerships and other funds, which are classified as VIEs. The entities are VIEs as equity holders lack the power to control the most significant activities of the entities because the equity holders do not have either the ability by a simple majority to exercise substantive kick-out rights or substantive participating rights. We have determined we are not the primary beneficiary because we do not have the power to direct the most significant activities of the entities.

As previously discussed, we sponsor and invest in certain investment funds that are VIEs. We determined we are not the primary beneficiary of the VIEs for which we are the asset manager but do not have a potentially significant variable interest in the funds.

We hold an equity interest in Mexican mandatory privatized social security funds in which we provide asset management services. Our equity interest in the funds is considered a variable interest. We concluded the funds are VIEs because the equity holders as a group lack decision-making ability through their voting rights. We are not the primary beneficiary of the VIEs because although we, as the asset manager, have the power to direct the activities of the VIEs, we do not have a potentially significant variable interest in the funds.

Our risk of loss is limited to our investment measured at fair value for our fixed maturities, trading and equity securities. Our risk of loss is limited to our carrying value plus any unfunded commitments and/or guarantees and similar provisions for our other investments. A carrying value of zero is used if distributions have been received in excess of our investment, resulting in a negative carrying value for the investment.

Money Market Funds

We are the investment manager for certain money market mutual funds. These types of funds are exempt from assessment under any consolidation model due to a scope exception for money market funds registered under Rule 2a-7 of the Investment Company Act of 1940 or similar funds. As of March 31, 2025 and December 31, 2024, money market mutual funds we manage held $4.4 billion and $4.5 billion in total assets, respectively. We have no contractual obligation to contribute to these funds; however, we provide support through the waiver of fees and through expense reimbursements. The amount of fees waived and expenses reimbursed was insignificant.

​

4. Investments

Our investments include assets backing reserves as part of a coinsurance with funds withheld agreement. The funds withheld invested assets are reported within their respective line items, primarily consisting of fixed maturities available-for-sale, mortgage loans and other investments. See Note 11, Reinsurance, for more information on the funds withheld invested assets.

Fixed Maturities

Fixed maturities include bonds, ABS, redeemable preferred stock and certain non-redeemable preferred securities. Equity securities include mutual funds, common stock, non-redeemable preferred stock and required regulatory investments. We classify fixed maturities as either available-for-sale or trading at the time of the purchase and, accordingly, carry them at fair value. Equity securities are also carried at fair value. See Note 17, Fair Value Measurements, for methodologies related to the determination of fair value. Unrealized gains and losses related to fixed maturities, available-for-sale, excluding those in fair value hedging relationships, are reflected in stockholders’ equity, net of adjustments associated with related actuarial balances, derivatives in cash flow hedge relationships and applicable income taxes. Mark-to-market adjustments on certain equity securities and mark-to-market adjustments on certain fixed maturities, trading are reflected in net realized capital gains (losses). Mark-to-market adjustments on certain fixed maturities, trading are reflected in market risk benefit remeasurement (gain) loss. Unrealized gains and losses related to hedged portions of fixed maturities, available-for-sale in fair value hedging relationships are reflected in net investment income. Mark-to-market adjustments related to certain securities carried at fair value with an investment objective to realize economic value through mark-to-market changes are reflected in net investment income.

The amortized cost of fixed maturities includes cost adjusted for amortization of premiums and discounts, computed using the interest method. The amortized cost of fixed maturities, available-for-sale is adjusted for changes in fair value of the hedged portions of securities in fair value hedging relationships and excludes accrued interest receivable. Accrued interest receivable is reported in accrued investment income on the consolidated statements of financial position. Fixed maturities, available-for-sale are subject to an allowance for credit loss and changes in the allowance are reported in net income as a component of net realized capital gains (losses). Interest income, as well as prepayment fees and the amortization of the related premium or discount, is reported in net investment income. For loan-backed and structured securities, we recognize income using a constant effective yield based on currently anticipated cash flows.

Net Realized Capital Gains and Losses

Net realized capital gains and losses on sales of investments are determined on the basis of specific identification. In general, in addition to realized capital gains and losses on investment sales and periodic settlements on derivatives not designated as hedges, we report gains and losses related to the following in net realized capital gains (losses) on the consolidated statements of operations: mark-to-market adjustments on certain equity securities, mark-to-market adjustments on certain fixed maturities, trading, mark-to-market adjustments on sponsored investment funds, mark-to-market adjustments on derivatives not designated as hedges, cash flow hedge gains (losses) when the hedged item impacts realized capital gains (losses), changes in the valuation allowance for fixed maturities available-for-sale and certain financing receivables, impairments of real estate held for investment and impairments on equity method investments. Investment gains and losses on sales of certain real estate held for sale due to investment strategy and mark-to-market adjustments on certain securities carried at fair value with an investment objective to realize economic value through mark-to-market changes are reported as net investment income and are excluded from net realized capital gains (losses).

Allowance for Credit Loss

We have a process in place to identify fixed maturity securities that could potentially require an allowance for credit loss. This process involves monitoring market events that could impact issuers’ credit ratings, business climate, management changes, litigation and government actions and other similar factors. This process also involves monitoring late payments, pricing levels, downgrades by rating agencies, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues.

Each reporting period, all securities in an unrealized loss position are reviewed to determine whether a decline in value is due to credit. Relevant facts and circumstances considered include: (1) the extent the fair value is below cost; (2) the reasons for the decline in value; (3) the financial position and access to capital of the issuer, including the current and future impact of any specific events and (4) for structured securities, the adequacy of the expected cash flows. To the extent we determine an unrealized loss is due to credit, an allowance for credit loss is recognized through a reduction to net income.

We estimate the amount of the allowance for credit loss as the difference between amortized cost and the present value of the expected cash flows of the security. The present value is determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The methodology and assumptions for establishing the best estimate cash flows vary depending on the type of security. The ABS cash flow estimates are based on security specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds and structural support, including subordination and guarantees. The corporate security cash flow estimates are derived from scenario-based outcomes of expected corporate restructurings or liquidations using bond specific facts and circumstances including timing, security interests and loss severity. We do not measure a credit loss allowance on accrued interest receivable because we write off the accrued interest receivable balance to net investment income in a timely manner when we have concern regarding collectability.

Amounts on fixed maturities, available-for-sale deemed to be uncollectible are written off and removed from the allowance for credit loss. A write-off may also occur if we intend to sell a security or whether it is more likely than not we will be required to sell the security before the recovery of its amortized cost which, in some cases, may extend to maturity.

A rollforward of the allowance for credit loss by major security type was as follows.

Of the total amounts, Principal Life Insurance Company’s (“Principal Life’s”) consolidated portfolio represented $42,666.1 million in available-for-sale fixed maturities with gross unrealized losses of $5,796.7 million. Of the available-for-sale fixed maturities within Principal Life’s consolidated portfolio in a gross unrealized loss position, 96% were investment grade (rated AAA through BBB-) with an average price of 88 (carrying value/amortized cost) as of March 31, 2025. Gross unrealized losses in our fixed maturities portfolio decreased during the three months ended March 31, 2025, primarily due to a decrease in interest rates, which was partially offset by a widening of credit spreads.

For those securities that had been in a continuous unrealized loss position for less than twelve months, Principal Life’s consolidated portfolio held 1,433 securities with a carrying value of $8,933.2 million and unrealized losses of $187.4 million reflecting an average price of 98 as of March 31, 2025. Of this portfolio, 95% was investment grade (rated AAA through BBB-) as of March 31, 2025, with associated unrealized losses of $182.5 million. The unrealized losses on these securities can primarily be attributed to changes in market interest rates and changes in credit spreads since the securities were acquired.

For those securities that had been in a continuous unrealized loss position greater than or equal to twelve months, Principal Life’s consolidated portfolio held 6,099 securities with a carrying value of $33,732.9 million and unrealized losses of $5,609.3 million as of March 31, 2025. The average credit rating of this portfolio was A with an average price of 86 as of March 31, 2025. Of the $5,609.3 million in unrealized losses, the corporate sector accounts for $3,236.9 million in unrealized losses with an average price of 86 and an average credit rating of BBB+. Furthermore, unrealized losses include $1,036.0 million within the states and political subdivisions sector with an average price of 82 and an average credit rating of AA-; $422.6 million within the collateralized mortgage obligation security sector with an average price of 85 and an average credit rating of AAA; and $387.3 million within the CMBS sector with an average price of 91 and an average credit rating of AA. The unrealized losses on these securities can primarily be attributed to changes in market interest rates and changes in credit spreads since the securities were acquired.

Because we expected to recover our amortized cost, we did not record an allowance for credit loss on these securities as of March 31, 2025. Because it was not our intent to sell the fixed maturity available-for-sale securities with unrealized losses and it was not more likely than not that we would be required to sell these securities before recovery of the amortized cost, which may be at maturity, we did not write down these investments to fair value.

Financing Receivables

Mortgage Loans

Mortgage loans consist of commercial and residential mortgage loans. Our commercial mortgage loan portfolio consists primarily of non-recourse, fixed rate mortgages on stabilized properties. Our residential mortgage loan portfolio is composed of first lien and home equity mortgages concentrated in Chile and the United States.

(Unaudited)

Commercial and residential mortgage loans are generally reported at cost adjusted for amortization of premiums and accrual of discounts, computed using the interest method and net of valuation allowances. Amortized cost excludes accrued interest receivable. The amortized cost of our residential mortgage loans also includes basis adjustments related to fair value hedges in a closed portfolio. See Note 5, Derivative Financial Instruments, for further information. Interest income is accrued on the principal amount of the loan based on the loan’s contractual interest rate. Interest income, as well as prepayment of fees and the amortization of the related premium or discount, is reported in net investment income on the consolidated statements of operations. Accrued interest receivable is reported in accrued investment income on the consolidated statements of financial position. Any changes in the loan valuation allowances are reported in net realized capital gains (losses) on the consolidated statements of operations. Further details relating to our valuation allowance are included under the caption “Financing Receivables Valuation Allowance.”

Direct Financing Leases

Our direct financing leases are concentrated in Chile. Our Chilean operations enter into private placement contracts for commercial, industrial and office space properties whereby our Chilean operations purchase the real estate and/or building from the seller-lessee but then lease the property back to the seller-lessee. Ownership of the property is transferred to the lessee by the end of the lease term. Direct financing leases are reported as a component of other investments in the consolidated statements of financial position.

Reinsurance Recoverable and Deposit Receivable

Our reinsurance recoverables include amounts due from reinsurers for paid or unpaid claims, claims incurred but not reported or policy benefits. We cede life, disability, medical and long-term care insurance as well as fixed annuity contracts with significant life insurance risk to other insurance companies through reinsurance. Deposit receivables include amounts due from the reinsurer for fixed annuity contracts without significant life insurance risk recorded using the deposit method of accounting.

Other Loans

Our other loans include consumer, auto and other loans (“other loans”) of a consolidated VIE for which the fair value option was elected as well as consumer loans for which the fair value option was not elected. Other loans are generally subject to amortized cost accounting and a valuation allowance if the fair value option is not elected. Other loans are reported as a component of other investments in the consolidated statements of financial position.

Financing Receivables Credit Monitoring

Commercial Mortgage Loan Credit Risk Profile Based on Internal Rating

We actively monitor and manage our commercial mortgage loan and direct financing lease portfolios. All commercial mortgage loans and direct financing leases are analyzed regularly and substantially all are internally rated, based on a proprietary risk rating cash flow model, in order to monitor the financial quality of these assets. The models stress expected cash flows at various levels and at different points in time depending on the durability of the income stream, which includes our assessment of factors such as location (macro and micro markets), tenant quality and lease expirations. Our internal rating analysis presents expected losses in terms of an S&P Global (“S&P”) bond equivalent rating for domestic commercial mortgage loans and Feller rate equivalent for Chilean commercial mortgage loans and direct financing leases. As the credit risk for commercial mortgage loans and direct financing leases increases, we adjust our internal ratings downward with loans in the category “B+ and below” having the highest risk for credit loss. Internal ratings on commercial mortgage loans and direct financing leases are updated at least annually and potentially more often for certain investments with material changes in collateral value or occupancy and for investments on an internal “watch list”.

Commercial mortgage loans and direct financing leases that require more frequent and detailed attention are identified and placed on an internal “watch list”. Among the criteria that may indicate a potential problem are significant negative changes in ratios of loan to value or contract rents to debt service, major tenant vacancies or bankruptcies, borrower sponsorship problems, late payments, delinquent taxes and loan relief/restructuring requests.

Residential Mortgage Loan Credit Risk Profile Based on Performance Status

Our residential mortgage loan portfolio is monitored based on performance of the loans. Monitoring on a residential mortgage loan increases when the loan is delinquent or earlier if there is an indication of potential impairment. We define non-performing domestic residential mortgage loans as loans 90 days or greater delinquent or on non-accrual status. We define non-performing residential first lien mortgages in the Chilean market as loans that have missed a specified number of coupon payments based on the nature of the loans and collection practices in that market.

Other Loans Credit Risk Profile Based on Performance Status

Our other loans are monitored based on performance of the loans. Monitoring on other loans increases when the loan is delinquent or earlier if there is an indication of potential impairment.

Non-Accrual Financing Receivables

Financing receivables are placed on non-accrual status if we have concern regarding the collectability of future payments or if a financing receivable has matured without being paid off or extended. Factors considered may include conversations with the borrower, loss of major tenant, bankruptcy of borrower or major tenant, decreased property cash flow for commercial mortgage loans and direct financing leases or number of days past due and other circumstances for residential mortgage loans. Based on an assessment as to the collectability of the principal, a determination is made to apply any payments received either against the principal, against the valuation allowance or according to the contractual terms. When a financing receivable is placed on non-accrual status, the accrued unpaid interest receivable is reversed against interest income. Accrual of interest resumes after factors resulting in doubts about collectability have improved. Financing receivables in the Chilean market are carried on accrual for a longer period of delinquency than domestic financing receivables, as assessment of collectability is based on the nature of the financing receivables and collection practices in that market.

Financing Receivables Valuation Allowance

We establish a valuation allowance to provide for the risk of credit losses inherent in our financing receivables. The valuation allowance is maintained at a level believed adequate by management to absorb estimated expected credit losses. The valuation allowance is based on amortized cost excluding accrued interest receivable and includes reserves for pools of financing receivables with similar risk characteristics. We do not measure a credit loss allowance on accrued interest receivable because we write off the uncollectible accrued interest receivable balance to net investment income in a timely manner, generally within 90 days domestically or, in the Chilean market, based on the nature of the loans and collection practices in that market. During 2025 and 2024, we did not write off any commercial mortgage loan accrued interest or residential mortgage loan accrued interest.

For commercial and residential mortgage loans and direct financing leases, management’s periodic evaluation and assessment of the valuation allowance adequacy is based on known and inherent risks in the portfolio, adverse situations that may affect a borrower’s ability to repay, the estimated value of the underlying collateral, composition of the portfolio, portfolio delinquency information, underwriting standards, peer group information, current and forecasted economic conditions, loss experience and other relevant factors. For reinsurance recoverables and deposit receivables, management’s periodic evaluation and assessment of the valuation allowance adequacy is based on known and inherent risks, adverse situations that may affect a reinsurer’s ability to repay, current and forecasted economic conditions, industry loss experience and other relevant factors.

Our commercial mortgage loans and direct financing leases are pooled by risk rating level with an estimated loss ratio applied against each risk rating level. The loss ratio is generally based upon historical loss experience for each risk rating level as adjusted for certain current and forecasted environmental factors management believes to be relevant. Environmental factors are forecasted for two years or less with immediate reversion to historical experience. The allowance for direct financing leases is also adjusted for the residual value of the leased assets. A commercial mortgage loan or direct financing lease is evaluated individually if it does not continue to share similar risk characteristics of a pool. We analyze the need for an individual evaluation for any domestic commercial mortgage loan that is delinquent for 60 days or more, in process of foreclosure, restructured, on the internal “watch list” or that currently is evaluated individually. We analyze the need for an individual evaluation for any Chilean commercial mortgage loan or direct financing lease that is considered past due based on collection practices in the Chilean market and the nature of the loan or lease.

We estimate expected credit losses for certain commercial mortgage loan or direct financing lease commitments where we have a contractual obligation to extend credit. The expected credit losses are estimated based on the commercial mortgage loan or direct financing lease valuation allowance process described previously, adjusted for probability of funding. The estimated expected credit losses for commercial mortgage loan and direct financing lease commitments are reported in other liabilities on the consolidated statements of financial position. The change in the credit loss liability for commitments is included in net realized capital gains (losses) on the consolidated statements of operations. Once funded, expected credit losses for commercial mortgage loans or direct financing leases are included within the commercial mortgage loan or direct financing lease valuation allowance described previously.

We evaluate residential mortgage loans based on aggregated risk factors and historical loss experience by pool type. We adjust these quantitative factors for qualitative factors of present and forecasted conditions. Qualitative factors include items such as economic and business conditions, changes in the portfolio, value of underlying collateral and concentrations. A residential mortgage loan is evaluated individually if it does not continue to share similar risk characteristics of a pool. We analyze the need for an individual evaluation for any domestic residential mortgage loan that is delinquent for 60 days or more, in process of foreclosure, restructured, on the internal “watch list” or that currently is evaluated individually. We analyze the need for an individual evaluation for any Chilean residential mortgage loan that is considered past due based on collection practices in the Chilean market and the nature of the loan.

As discussed previously, commercial and residential mortgage loans and direct financing leases are evaluated individually if the asset does not continue to share similar risk characteristics of a pool. When we determine a commercial or residential mortgage loan is probable of foreclosure, a valuation allowance is established equal to the difference between the carrying amount of the mortgage loan and the estimated value of the collateral reduced by the cost to sell or for certain residential mortgage loans, the present value of the loan’s expected future cash flows. For certain commercial mortgage loans where repayment is expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty, we elect to establish a valuation allowance equal to the difference between the carrying amount of the mortgage loan and the estimated value of the real estate collateral, which may be reduced by the cost to sell. Estimated value may also be based on either the present value of the expected future cash flows discounted at the asset’s effective interest rate or the asset’s observable market price. Subsequent changes in the estimated value are reflected in the valuation allowance. Amounts on financing receivables deemed to be uncollectible are charged off and removed from the valuation allowance. The change in the valuation allowance for loans and direct financing leases is included in net realized capital gains (losses) on the consolidated statements of operations.

Our reinsurance recoverables and deposit receivable are pooled by reinsurer risk rating with an estimated loss ratio applied against each risk rating level. The loss ratio is generally based upon industry historical loss experience and expected recovery timing as adjusted for certain current and forecasted environmental factors management believes to be relevant. Environmental factors are forecasted for five years or less with immediate reversion to industry historical experience. A reinsurance recoverable or deposit receivable is evaluated individually if it does not continue to share similar risk characteristics of a pool. We analyze the need for an individual evaluation for any reinsurance recoverable or deposit receivable based on past due payments and changes in reinsurer risk ratings. The change in the valuation allowance for reinsurance recoverables and deposit receivable is included in benefits, claims and settlement expenses on the consolidated statements of operations.

Mortgage Loan Modifications

Our commercial and residential mortgage loan portfolios include loans that have been modified. We assess loan modifications that are related to our borrowers experiencing financial difficulty in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay or a term extension (or a combination thereof). Generally, an assessment of whether a borrower is experiencing financial difficulty is made on the date of the modification.

The financing receivables valuation allowance utilizes an estimate of lifetime expected credit losses and it is recorded on each loan upon origination or acquisition. The starting point for the estimate of the valuation allowance is historical loss information, which includes losses from modification of receivables to borrowers experiencing financial difficulty. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the valuation allowance because of the measurement methodologies used to estimate the allowance, a change to the valuation allowance is generally not recorded upon modification.

Occasionally, a modification of a loan from a borrower experiencing financial difficulty is in the form of principal forgiveness. When principal forgiveness is provided as a modification, the amount of the principal forgiven is deemed uncollectible. Therefore, that portion of the loan is written off, which results in a reduction of the amortized cost and a corresponding adjustment to the valuation allowance.

In some cases, we modify a loan by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession such as principal forgiveness may be granted.

We did not have any significant mortgage loans that were modified for both the three months ended March 31, 2025 and 2024.

Securities Posted as Collateral

As of March 31, 2025 and December 31, 2024, we posted $6,856.7 million and $6,748.8 million, respectively, in commercial mortgage loans and residential first lien mortgages to satisfy collateral requirements associated with our obligation under funding agreements with Federal Home Loan Bank of Des Moines (“FHLB Des Moines”). In addition, as of March 31, 2025 and December 31, 2024, we posted $3,772.9 million and $3,636.7 million, respectively, in fixed maturities, available-for-sale and trading securities to satisfy collateral requirements primarily associated with a reinsurance arrangement, our derivative credit support annex (collateral) agreements, Futures Commission Merchant (“FCM”) agreements, a lending arrangement and our obligation under funding agreements with FHLB Des Moines. Since we did not relinquish ownership rights on these instruments, they are reported as mortgage loans, fixed maturities, available-for-sale and fixed maturities, trading, respectively, on our consolidated statements of financial position. Of the securities posted as collateral, as of March 31, 2025 and December 31, 2024, $364.9 million and $206.0 million, respectively, could be sold or repledged by the secured party.

The financial instruments that are subject to master netting agreements or similar agreements include right of setoff provisions. Derivative instruments include provisions to setoff positions covered under the agreements with the same counterparties and provisions to setoff positions outside of the agreements with the same counterparties in the event of default by one of the parties. Derivative instruments also include collateral or variation margin provisions, which are generally settled daily with each counterparty. See Note 5, Derivative Financial Instruments, for further details.

Repurchase and reverse repurchase agreements include provisions to setoff other repurchase and reverse repurchase balances with the same counterparty. Repurchase and reverse repurchase agreements also include collateral provisions with the counterparties. For reverse repurchase agreements we require the counterparties to pledge collateral with a value greater than the amount of cash transferred. We have the right but do not sell or repledge collateral received in reverse repurchase agreements. Repurchase agreements are structured as secured borrowings for all counterparties. We pledge fixed maturities available-for-sale, which the counterparties have the right to sell or repledge. Interest incurred on repurchase agreements is reported as part of operating expenses on the consolidated statements of operations. Net proceeds related to repurchase agreements are reported as a component of financing activities on the consolidated statements of cash flows. We did not have any outstanding repurchase agreements as of March 31, 2025 and December 31, 2024.

5. Derivative Financial Instruments

Derivatives are generally used to hedge or reduce exposure to market risks associated with assets held or expected to be purchased or sold and liabilities incurred or expected to be incurred. Derivatives are used to change the characteristics of our asset/liability mix consistent with our risk management activities. Derivatives are also used in asset replication and income generation strategies.

Types of Derivative Instruments

Interest Rate Contracts

Interest rate risk is the risk we will incur economic losses due to adverse changes in interest rates. Sources of interest rate risk include the difference between the maturity and interest rate changes of assets with the liabilities they support, timing differences between the pricing of liabilities and the purchase or procurement of assets and changing cash flow profiles from original projections due to prepayment options embedded within asset and liability contracts. We use various derivatives to manage our exposure to fluctuations in interest rates.

(Unaudited)

Interest rate swaps are contracts in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and/or floating rate interest amounts based upon designated market rates or rate indices and an agreed-upon notional principal amount. Generally, no cash is exchanged at the outset of the contract and no principal payments are made by any party. Cash is paid or received based on the terms of the swap. We use interest rate swaps primarily to more closely match the interest rate characteristics of assets and liabilities and to mitigate the risks arising from timing mismatches between assets and liabilities (including duration mismatches). We also use interest rate swaps to hedge against changes in the value of assets we anticipate acquiring and other anticipated transactions and commitments; to hedge against cash variability related to forecasted transactions and to hedge against changes in the value of the guaranteed minimum withdrawal benefit (“GMWB”) MRB. The GMWB rider on our variable annuity products provides for guaranteed minimum withdrawal benefits regardless of the actual performance of various equity and/or fixed income funds available with the product. Additionally, we utilize interest rate swaps to replicate the returns of floating rate assets.

Interest rate options, including interest rate caps and interest rate floors, which can be combined to form interest rate collars, are contracts that entitle the purchaser to pay or receive the amounts, if any, by which a specified market rate exceeds a cap strike interest rate, or falls below a floor strike interest rate, respectively, at specified dates. We use interest rate options to manage prepayment risks in our assets and minimum guaranteed interest rates and lapse risks in our liabilities.

A swaption is an option to enter into an interest rate swap at a future date. We have purchased swaptions to hedge interest rate exposure for certain assets and liabilities. Swaptions not only hedge against the downside risk, but also allow us to take advantage of any upside benefits.

In exchange-traded futures transactions, we agree to purchase or sell a specified number of contracts, the values of which are determined by the values of designated classes of securities, and to post variation margin on a daily basis in an amount equal to the difference in the daily market values of those contracts. We enter into exchange-traded futures with regulated futures commissions merchants who are members of a trading exchange. We use exchange-traded interest rate futures to hedge against changes in value of the GMWB MRB in addition to the economic exposure to certain fund strategies.

Interest rate forwards, including to be announced (“TBA”) forwards, bond forwards and treasury forwards, are contracts to take delivery of a fixed income security at a specified price at a future date. TBA forwards deliver government guaranteed mortgage-backed securities. Bond forwards and treasury forwards deliver corporate or municipal and U.S. Treasury bonds, respectively. At inception of the TBA and certain treasury forward contracts we do not intend to take physical delivery. We intend to take delivery of the bond forwards referencing corporate, municipal and certain treasury bonds. We have used TBA forwards to gain exposure to the investment risk and return of agency mortgage-backed security pools in order to reduce asset and liability duration mismatch. Treasury forwards are used to hedge against changes in the value of the GMWB MRB and to more closely match the interest rate characteristics of assets and liabilities. Bond forwards are used to gain leverage through synthetic exposure during the forward period and fix the purchase price of a bond at a specified date in future.

Foreign Exchange Contracts

Foreign currency risk is the risk we will incur economic losses due to adverse fluctuations in foreign currency exchange rates. This risk arises from foreign currency-denominated funding agreements issued to nonqualified institutional investors in the international market, foreign currency-denominated fixed maturity and equity securities, and our international operations, including expected cash flows and potential acquisition and divestiture activity. We use various derivatives to manage our exposure to fluctuations in foreign currency exchange rates.

Currency swaps are contracts in which we agree with other parties to exchange, at specified intervals, a series of principal and interest payments in one currency for that of another currency. Generally, the principal amount of each currency is exchanged at the beginning and termination of the currency swap by each party. The interest payments are primarily fixed-to-fixed rate; however, they may also be fixed-to-floating rate or floating-to-fixed rate. These transactions are entered into pursuant to master agreements that provide for a single net payment to be made by one counterparty for payments made in the same currency at each due date. We use currency swaps to reduce market risks from changes in currency exchange rates with respect to investments or liabilities denominated in foreign currencies that we either hold or intend to acquire or sell.

Currency forwards are contracts in which we agree with other parties to deliver or receive a specified amount of an identified currency at a specified future date. Typically, the price is agreed upon at the time of the contract and payment for such a contract is made at the specified future date. We use currency forwards to reduce market risks from changes in currency exchange rates with respect to investments or liabilities denominated in foreign currencies that we either hold or intend to acquire or sell.

Equity Contracts

Equity risk is the risk that we will incur economic losses due to adverse fluctuations in common stock prices. We use various derivatives to manage our exposure to equity risk, which arises from products in which the return or interest we credit is tied to an external equity index as well as products subject to minimum contractual guarantees.

We purchase equity call spreads (“option collars”) to hedge the equity participation rates promised to contractholders in conjunction with our fixed deferred annuity and universal life products that credit interest based on changes in an external equity index.

We use equity put options to hedge against changes in the value of the GMWB MRB related to the GMWB rider on our variable annuity products. We also use equity options to hedge returns credited to policyholder accounts related to our RILA products. The premium associated with certain options is paid quarterly over the life of the option contract.

We use exchange-traded equity futures to hedge against changes in the value of the GMWB MRB and returns credited to policyholder accounts related to our RILA products. We have used equity futures to hedge the economic exposure to certain fund closures in process.

We use equity total return swaps to hedge for income enhancement. Total return swaps are contracts in which we agree with other parties to periodically exchange the total return on a referenced security for an agreed-upon reference rate or spread based on specified notional amounts.

Credit Contracts

Credit risk relates to the uncertainty associated with the continued ability of a given obligor to make timely payments of principal and interest. We use credit default swaps to enhance the return on our investment portfolio by providing comparable exposure to fixed income securities that might not be available in the primary market. They are also used to hedge credit exposures in our investment portfolio. Credit derivatives are used to sell or buy credit protection on an identified name or names on an unfunded or synthetic basis in return for receiving or paying a quarterly premium. The premium generally corresponds to a referenced name’s credit spread at the time the agreement is executed.

We also use credit total return swaps for income enhancement. In the case of a predefined credit event, total return swaps require the total return receiver to pay for the decline in the price of the referenced security.

In cases where we sell protection, we also buy a quality cash bond to match against the swap, thereby entering into a synthetic transaction replicating a cash security. When selling protection, if there is an event of default by the referenced name, as defined by the agreement, we are obligated to pay the counterparty the referenced amount of the contract and receive in return the referenced security in a principal amount equal to the notional value of the swap.

Other Contracts

Embedded Derivatives. We purchase or issue certain financial instruments or products that contain a derivative instrument that is embedded in the financial instrument or product. When it is determined that the embedded derivative possesses economic characteristics that are not clearly or closely related to the economic characteristics of the host contract and a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is bifurcated from the host instrument for measurement purposes. The embedded derivative, which is reported with the host instrument in the consolidated statements of financial position, is carried at fair value.

We offer group annuity contracts that have guaranteed separate accounts as an investment option. We have fixed deferred annuities, RILAs and universal life products that credit interest based on changes in an external equity index.

We have a funds withheld payable associated with coinsurance with funds withheld reinsurance agreements. The funds withheld payable has an embedded total return swap as the total return of the funds withheld assets are transferred to the reinsurer, which is not based on our own creditworthiness.

Exposure

Our risk of loss is typically limited to the fair value of our derivative instruments and not to the notional or contractual amounts of these derivatives. We are also exposed to credit losses in the event of nonperformance of the counterparties. Our current credit exposure is limited to the value of derivatives that have become favorable to us. This credit risk is minimized by purchasing such agreements from financial institutions with high credit ratings and by establishing and monitoring exposure limits. We also utilize various credit enhancements, including collateral and credit triggers to reduce the credit exposure to our derivative instruments.

Derivatives may be exchange-traded or they may be privately negotiated contracts, which are usually referred to as over-the-counter (“OTC”) derivatives. Certain of our OTC derivatives are cleared and settled through central clearing counterparties (“OTC cleared”), while others are bilateral contracts between two counterparties (“bilateral OTC”). Our derivative transactions are generally documented under International Swaps and Derivatives Association, Inc. (“ISDA”) Master Agreements. Management believes that such agreements provide for legally enforceable set-off and close-out netting of exposures to specific counterparties. Under such agreements, in connection with an early termination of a transaction, we are permitted to set off our receivable from a counterparty against our payables to the same counterparty arising out of all included transactions. For reporting purposes, we do not offset fair value amounts of bilateral OTC derivatives for the right to reclaim cash collateral or the obligation to return cash collateral against fair value amounts recognized for derivative instruments executed with the same counterparties under master netting agreements. OTC cleared derivatives have variation margin that is legally characterized as settlement of the derivative exposure, which reduces their fair value in the consolidated statements of financial position.

We posted $539.4 million and $533.7 million in cash and securities under collateral arrangements as of March 31, 2025 and December 31, 2024, respectively, to satisfy collateral and initial margin requirements associated with our derivative credit support agreements and FCM agreements.

Certain of our derivative instruments contain provisions that require us to maintain an investment grade rating from each of the major credit rating agencies on our debt. If the ratings on our debt were to fall below investment grade, it would be in violation of these provisions and the counterparties to the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions. The aggregate fair value, inclusive of accrued interest, of all derivative instruments with credit-risk-related contingent features that were in a liability position without regard to netting under derivative credit support annex agreements as of March 31, 2025 and December 31, 2024, was $420.0 million and $472.3 million, respectively. Cleared derivatives have contingent features that require us to post excess margin as required by the FCM. The terms surrounding excess margin vary by FCM agreement. With respect to derivatives containing collateral provisions, we posted collateral and initial margin of $539.4 million and $533.7 million as of March 31, 2025 and December 31, 2024, respectively, in the normal course of business, which reflects netting under derivative agreements. If the credit-risk-related contingent features underlying these agreements were triggered on March 31, 2025, we would be required to post up to an additional $108.2 million of collateral to our counterparties.

As of March 31, 2025 and December 31, 2024, we had received $332.7 million and $358.9 million, respectively, of cash collateral associated with our derivative credit support annex agreements and FCM agreements, for which we recorded a corresponding liability reflecting our obligation to return the collateral.

Notional amounts are used to express the extent of our involvement in derivative transactions and represent a standard measurement of the volume of our derivative activity. Notional amounts represent those amounts used to calculate contractual flows to be exchanged and are not paid or received, except for contracts such as currency swaps. Credit exposure represents the gross amount owed to us under derivative contracts as of the valuation date.

Embedded derivatives with a net liability fair value of $522.7 million and $578.4 million as of March 31, 2025 and December 31, 2024, respectively, are reported with contractholder funds on the consolidated statements of financial position. Embedded derivatives with a net (asset) liability fair value of $(2,804.8) million and $(3,014.5) million as of March 31, 2025 and December 31, 2024, respectively, are reported with funds withheld payable on the consolidated statements of financial position.

Credit Derivatives Sold

When we sell credit protection, we are exposed to the underlying credit risk similar to purchasing a fixed maturity security instrument. Our credit derivative contracts sold reference a single name or reference security (referred to as “single name credit default swaps” or “single name total return swaps”). These instruments are either referenced in an OTC credit derivative transaction or embedded within an investment structure that has been fully consolidated into our financial statements.

These credit derivative transactions are subject to events of default defined within the terms of the contract, which normally consist of bankruptcy, failure to pay, or modified restructuring of the reference entity and/or issue. If a default event occurs for a reference name or security, we are obligated to pay the counterparty an amount equal to the notional amount of the credit derivative transaction. As a result, our maximum future payment is equal to the notional amount of the credit derivative. In certain cases, we also may have purchased credit protection with identical underlyings to certain of our sold protection transactions. As of March 31, 2025 and December 31, 2024, we did not purchase credit protection relating to our sold protection transactions. In certain circumstances, our potential loss could also be reduced by any amount recovered in the default proceedings of the underlying credit name.

Fair Value and Cash Flow Hedges

Fair Value Hedges

We use fixed-to-floating rate interest rate swaps to more closely align the interest rate characteristics of certain assets and also use them to align the interest rate characteristics of certain liabilities. In general, these swaps are used in asset and liability management to modify duration, which is a measure of sensitivity to interest rate changes.

We enter into currency exchange swap agreements to convert certain foreign denominated assets into U.S. dollar denominated instruments to hedge the exposure to future currency volatility on those items.

The net interest effect of interest rate swap and currency swap transactions for derivatives in fair value hedges is recorded as an adjustment to income or expense of the underlying hedged item in our consolidated statements of operations. The currency related impacts of currency swap transactions for derivatives in fair value hedges is recorded as an adjustment to net realized capital gains or losses of the underlying hedged item in our consolidated statements of operations.

The following amounts were recorded on the consolidated statements of financial position related to cumulative basis adjustments for fair value hedges. The amortized cost includes the amortized cost basis and the fair value hedging basis adjustment.

For the three months ended March 31, 2025 and 2024, $1.1 million and $0.0 million, respectively, of the derivative instruments’ gains (losses) were excluded from the assessment of hedge effectiveness.

Cash Flow Hedges

We utilize floating-to-fixed rate interest rate swaps to eliminate the variability in cash flows of recognized financial assets and liabilities.

We enter into currency exchange swap agreements to convert both principal and interest payments of certain foreign denominated assets and liabilities into U.S. dollar denominated fixed rate instruments to eliminate the exposure to future currency volatility on those items.

We use bond forwards and floating-to-fixed rate interest rate swaps to hedge forecasted transactions.

The net interest effect of interest rate swap and currency swap transactions for derivatives in cash flow hedges is recorded as an adjustment to income or expense of the underlying hedged item in our consolidated statements of operations.

The maximum length of time we are hedging our exposure to the variability in future cash flows for forecasted transactions, excluding those related to the payments of variable interest on existing financial assets and liabilities, is 1.9 years. As of March 31, 2025, we had $6.5 million of net gains reported in AOCI on the consolidated statements of financial position related to active hedges of forecasted transactions. If a hedged forecasted transaction is no longer probable of occurring, cash flow hedge accounting is discontinued. If it is probable that the hedged forecasted transaction will not occur, the deferred gain or loss is immediately reclassified from AOCI into net income.

The following table shows the effect of derivatives in cash flow hedging relationships on the consolidated statements of financial position.

​

​

We expect to reclassify net gains of $22.1 million from AOCI into net income in the next twelve months, which includes both net deferred gains on discontinued hedges and net gains on periodic settlements of active hedges. Actual amounts may vary from this amount as a result of market conditions.

Net Investment Hedges

We may take measures to hedge our net equity investments in our foreign operations from currency risk. This is accomplished with the use of currency forwards.

Gains and losses associated with net investment hedges are recorded in AOCI and will be released into net income if our investment in the foreign operation is sold or substantially liquidated.

Derivatives Not Designated as Hedging Instruments

We use futures, certain swaptions and swaps, option collars, options and forwards in effective economic hedges that have not been designated as hedges for financial reporting purposes. As such, periodic changes in the market value of these instruments, which includes mark-to-market gains and losses as well as periodic and final settlements, primarily flow directly into net realized capital gains (losses) on the consolidated statements of operations. However, the change in fair value of the funds withheld embedded derivative is separately reported on the consolidated statements of operations. Additionally, mark-to-market gains and losses as well as periodic and final settlements for derivatives used to hedge market risk benefits are reported in market risk benefit (gain) loss on the consolidated statements of operations.

The following table shows the effect of derivatives not designated as hedging instruments, including fair value changes of embedded derivatives that have been bifurcated from the host contract, on the consolidated statements of operations and are net of amounts on funds withheld invested assets that are passed directly to the reinsurer. See Note 11, Reinsurance, for further details.

6. Deferred Acquisition Costs and Other Actuarial Balances

Deferred Acquisition Costs

Incremental direct costs of contract acquisition as well as certain costs directly related to acquisition activities (underwriting, policy issuance and processing, medical and inspection and sales force contract selling) for the successful acquisition of new and renewal insurance policies and investment contracts are capitalized in the period they are incurred. Maintenance costs and acquisition costs that are not deferrable are charged to operating expenses as incurred.

For our long-duration insurance products and certain investment contracts, DAC is amortized on a constant level basis over the expected life of the contracts using groupings and assumptions consistent with those used in computing policyholder liabilities. For each of our long-duration insurance products, we select an inforce measure as a basis for amortization that will result in a constant level amortization pattern for the expected life of the contract. If our actual contract terminations differ from our expectation, the amortization pattern is adjusted on a prospective basis.

Some of our life and disability products within the Benefits and Protection segment have renewal commissions resulting in new DAC capitalizations in the years following the initial capitalization. We also have life products that allow for underwritten death benefit increases and cost of living adjustments, resulting in an immaterial amount of new DAC capitalizations each year. The new capitalizations are added to the existing DAC balance when incurred and amortized over the remaining life of the business.

DAC on short-duration group benefits contracts is amortized over the estimated life of the underlying contracts.

We review and update actuarial experience assumptions (such as mortality, surrenders, lapse, and premium persistency) serving as inputs to the models that establish the expected life for DAC and other actuarial balances during the third quarter of each year, or more frequently if evidence suggests assumptions should be revised. We make model refinements as necessary, and any changes resulting from these assumption updates are applied prospectively.

DAC amortization expense of $98.5 million and $97.3 million related to our long-duration and short-duration contracts was recorded in operating expenses on the consolidated statements of operations for the three months ended March 31, 2025 and 2024, respectively.

The following tables summarize disaggregated DAC amounts and reconcile the totals to those reported in the consolidated statements of financial position.

Unearned Revenue Liability

An unearned revenue liability is established when we collect fees or other policyholder assessments, inclusive of cost of insurance charges, administrative charges and other similar fees, for services to be provided in future periods. These unearned front-end fees are deferred and the amortization is recorded using an approach consistent with DAC.

The unearned revenue liability is included within other policyholder funds in the consolidated statements of financial position. The following table summarizes disaggregated unearned revenue liability amounts and reconciles the totals to those reported in the consolidated statements of financial position.

7. Separate Account Balances

The separate accounts are legally segregated and are not subject to claims that arise out of any of our other business. The client, rather than us, directs the investments and bears the investment risk of these funds. The separate account assets represent the fair value of funds that are separately administered by us for contracts with equity, real estate and fixed income investments and are presented as a summary total within the consolidated statements of financial position. An equivalent amount is reported as separate account liabilities, which represent the obligation to return the monies to the client. Refer to Note 17, Fair Value Measurements, for further information on the valuation methodologies.

We receive fees for mortality, withdrawal and expense risks, as well as administrative, maintenance and investment advisory services that are included in the consolidated statements of operations. Net deposits, net investment income and realized and unrealized capital gains and losses of the separate accounts are not reflected in the consolidated statements of operations.

The Retirement and Income Solutions segment offers variable annuity contracts that allow the policyholder to allocate deposits into various investment options in a separate account. The variable annuity contracts can also include GMWB riders and guaranteed minimum death benefit (“GMDB”) riders that are accounted for as MRBs. Retirement and Income Solutions also offers certain group annuity contracts that have separate accounts as an investment option.

The Principal Asset Management segment offers certain retirement accumulation products in Latin America where the segregated funds and associated obligation to the client are consolidated as separate account assets and liabilities within the financial statements. We have determined that summary totals are the most meaningful presentation for these funds.

The Benefits and Protection segment offers variable universal life products with separate account investment options.

Refer to Note 10, Market Risk Benefits, for further information on the MRBs associated with the contracts mentioned above.

As of March 31, 2025 and December 31, 2024, the separate accounts included a separate account valued at $85.2 million and $79.8 million, respectively, which primarily included shares of our stock that were allocated and issued to eligible participants of qualified employee benefit plans administered by us as part of the policy credits issued under our 2001 demutualization. These shares are included in both basic and diluted earnings per share calculations. In the consolidated statements of financial position, the separate account shares are recorded at fair value and are reported as separate account assets with a corresponding separate account liability. Changes in fair value of the separate account shares are reflected in both the separate account assets and separate account liabilities and do not impact our results of operations.

Liability for Unpaid Claims

The liability for unpaid claims is reported in future policy benefits and claims within our consolidated statements of financial position. Activity associated with unpaid claims was as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | For the three months ended March 31,
​ |  | 2025 |  | 2024
​ | ​ | (in millions)
Balance at beginning of period | ​ | $ | 1,379.9 | ​ | $ | 1,405.9
Less: reinsurance recoverable | ​ |  | 61.2 | ​ |  | 67.8
Net balance at beginning of period | ​ |  | 1,318.7 | ​ |  | 1,338.1
Incurred: | ​ |  | ​ | ​ |  | ​
Current year | ​ |  | 472.5 | ​ |  | 458.0
Prior years | ​ |  | (42.4) | ​ |  | (47.4)
Total incurred | ​ |  | 430.1 | ​ |  | 410.6
Payments: | ​ |  | ​ | ​ |  | ​
Current year | ​ |  | 256.1 | ​ |  | 240.3
Prior years | ​ |  | 175.0 | ​ |  | 173.0
Total payments | ​ |  | 431.1 | ​ |  | 413.3
Net balance at end of period | ​ |  | 1,317.7 | ​ |  | 1,335.4
Plus: reinsurance recoverable | ​ |  | 61.0 | ​ |  | 64.5
Balance at end of period | ​ | $ | 1,378.7 | ​ | $ | 1,399.9

​

Incurred liability adjustments relating to prior years, which affected current operations during 2025 and 2024, resulted in part from developed claims for prior years being different than were anticipated when the liabilities for unpaid claims were originally estimated. These trends have been considered in establishing the current year liability for unpaid claims.

Liability for Future Policy Benefits

The liability for future policy benefits (“LFPB”) for individual and group annuities is generally equal to the present value of expected future policy benefit payments. The reserves are computed using assumptions for mortality and interest. The LFPB for non-participating term life insurance, individual disability income contracts and individual and group long-term care contracts is generally equal to the present value of expected future policy benefit payments less the present value of expected net premiums. The reserves are computed using assumptions for mortality, interest, morbidity and lapse. Cohorts are used as the unit of account for liability measurement. Actual cash flows are grouped into issue-year cohorts for the liability calculation and updated quarterly. We review and update, if necessary, assumptions used to measure cash flows for the LFPB during the third quarter of each year, or more frequently if evidence suggests assumptions should be revised. The change in our liability estimate as a result of updating cash flow assumptions is recognized in net income.

An interest accretion rate is determined for an identified cohort and remains unchanged after the issue year. For policies issued on or prior to December 31, 2020, the interest accretion rate is based on the assumed investment yield when the business was issued. For policies issued after December 31, 2020, the interest accretion rate is based on the upper-medium grade fixed-income instrument yields, which is generally equivalent to a single-A rated bond yield matched to the duration of our insurance liabilities, when the business was issued.

The LFPB is remeasured to reflect current upper-medium grade fixed-income instrument yields as of each reporting date. The liability is calculated by discounting cash flows using rate curves reflecting the currency and duration of the insurance liabilities. For discount rate tenors, or points on the curves, where the upper-medium grade fixed-income instrument yields are not liquid or limited observable market data is available, we use various estimation techniques consistent with fair value measurement guidance.

For our individual fixed income annuities in Latin America, the discount rate methodology is designed to prioritize observable inputs based on market data available in the local debt markets where the respective policies are issued in the currency in which the policies are denominated. For discount rate tenors where upper-medium grade fixed-income instrument yields based on international rating standards are not liquid or limited observable market data is available, estimation techniques are used to determine a curve in the appropriate currency.

Further details regarding reference rates used are included under “Interest Accretion and Current Discount Rates.”

We updated our actuarial assumptions during the third quarter of 2024, resulting in a $32.3 million increase in the LFPB and an $18.2 million decrease to income before taxes, net of reinsurance, for Individual disability. This was primarily due to unfavorable updates to termination and lapse assumptions. The updates also resulted in a $68.2 million increase in the LFPB and a $52.9 million decrease to income before taxes, net of reinsurance, for Term life. This was primarily due to unfavorable updates to mortality and lapse assumptions.

Additional Liability for Certain Benefit Features

The LFPB also includes an additional reserve on certain universal life contracts where benefit features result in gains in early years followed by losses in later years. The liability for these future losses is accrued in relation to estimated contract assessments. A premium deficiency exists if the net liabilities together with future premiums are determined to be insufficient to provide for expected future policy benefits. Premium deficiency testing considers, among other factors, anticipated investment income and does not include a provision for adverse deviation. We did not have a premium deficiency reserve as of March 31, 2025 or December 31, 2024.

The balances and the changes in the additional liability for certain benefit features for Life Insurance - Universal life contracts, excluding the impact of unrealized gains (losses), were as follows:

Interest Accretion and Current Discount Rates

The interest accretion rate shown for each level of aggregation is an average of the cohort-level accretion rates weighted by the reserve balance for each cohort within that level of aggregation. The current discount rate is calculated at a cohort-level based on current upper-medium fixed-income instrument yields and weighted by the reserve balance for each cohort within each level of aggregation. The weighted-average rates were as follows:

Contracts or contract features that provide protection to the policyholder from capital market risk, including equity, interest rate or foreign exchange risk, and expose us to other-than-nominal capital market risk are classified as MRBs. We issue certain annuity contracts and other investment contracts that include MRBs that have been bifurcated from the host contract. The Retirement and Income Solutions segment offers variable annuity products with GMWB riders and GMDB riders, including return-of-premium GMDB and GMWB riders for its RILA products.

MRBs are measured at fair value at the contract level and can be in either an asset or liability position, depending on certain inputs at the reporting date. MRB assets and liabilities are presented separately within the consolidated statements of financial position. Increases to an asset or decreases to a liability are described as favorable changes to fair value.

Changes in fair value are reported in MRB remeasurement (gain) loss on the consolidated statements of operations. However, the change in fair value related to our own nonperformance risk is reported in OCI. For contracts that contain multiple MRB features, the MRBs are valued on a combined basis using an integrated model.

MRBs are classified as Level 3 fair value measurements as the fair value is based on unobservable inputs. The key assumptions for calculating the fair value of the MRBs are market assumptions such as equity market returns, interest rate levels, market volatility and correlations and policyholder behavior assumptions such as lapse, mortality, utilization and withdrawal patterns. Risk margins are included in the policyholder behavior assumptions. The assumptions are based on a combination of historical data and actuarial judgment. The MRBs are valued using stochastic models that incorporate a spread reflecting our own nonperformance risk.

The assumption for our own nonperformance risk for MRBs is based on the current market credit spreads for debt-like instruments we have issued and are available in the market. Increases (decreases) in our own nonperformance risk, which impacts the rates used to discount future cash flows, could lead to favorable (unfavorable) changes in the fair value of the MRBs.

Long-term interest rates are used as the mean return when projecting the growth in the value of the associated account value and impact the discount rate used in the discounted future cash flows valuation. The amount of claims will increase if account value is not sufficient to cover guaranteed withdrawals. An increase (decrease) in risk-free rates could cause a favorable (unfavorable) change in the fair value of the MRBs. A decrease (increase) in market volatilities could cause a favorable (unfavorable) change in the fair value of the MRBs.

An increase (decrease) in mortality rates or the overall lapse rate assumptions could cause a favorable (unfavorable) change in the fair value of the MRBs. The lapse rate assumption may vary dynamically based on the relationship between the guarantee and associated account value. A weaker (stronger) dynamic lapse rate assumption could lead to favorable (unfavorable) changes in the fair value of the MRBs.

The utilization rate assumption includes how many contractholders will take withdrawals, when they will take them and how much of their benefit they will take. A decrease (increase) in the number of contractholders taking withdrawals, contractholders taking withdrawals earlier versus later, or contractholders taking more versus less of their benefit could lead to favorable (unfavorable) changes in the fair value of the MRBs.

The following tables summarize disaggregated MRB amounts in an asset and liability position reported in the consolidated statements of financial position.

Net amount at risk (2) | ​ | $ | 132.4 | ​ | $ | 46.8

(1) | The weighted-average attained age is calculated at the contract level using the total contributions since inception and the age of the contractholders.

(2) | The net amount at risk for our GMDB riders is defined as the current GMDB amount in excess of the current account balance. The net amount at risk for our GMWB riders is defined as the greater of the present value of the GMWB payments less the current account balance or zero. For contracts with both GMDB and GMWB riders, the net amount at risk is the greater of the GMDB or GMWB net amount at risk. We had an increase in the net amount at risk in 2025 primarily as a result of decreases in the equity markets.

​

Significant changes to inputs and assumptions that impacted the change in the MRB fair value measurement shown above were as follows:

​

​ | ​ | For the three months ended | ​ | For the year ended
​ | ​ | March 31, 2025 | ​ | December 31, 2024
​ |  | ​ |  | Change in net |  | ​ |  | Change in net
​ | ​ | Change in input | ​ | MRB asset (liability) | ​ | Change in input | ​ | MRB asset (liability)
Long-term interest rate | ​ | Decreased | ​ | Unfavorable | ​ | Increased | ​ | Favorable
Equity markets | ​ | Decreased | ​ | Unfavorable | ​ | Increased | ​ | Favorable
Equity market volatilities | ​ | Decreased | ​ | Unfavorable (1) | ​ | Decreased | ​ | Favorable
Own nonperformance risk | ​ | Increased | ​ | Favorable | ​ | Decreased | ​ | Unfavorable

(1) | The weighted - average equity market volatility input is calculated using market - implied volatilities and the difference between account values and the present value of future benefits. An equity market decline during first quarter 2025 shifted this calculation, moving the block along the volatility curve. As a result, the weighted - average market volatility input decreased despite rising equity market volatility, which results in unfavorable impacts to the net MRB asset (liability).

11. Reinsurance

We reinsure a portion of the insurance risks associated with our individual disability, traditional life, universal life, medical and long-term care insurance as well as retail fixed annuity contracts with significant life insurance risk through reinsurance agreements with unaffiliated reinsurance companies, primarily on a quota share, excess loss, yearly renewable term (“YRT”) or coinsurance basis. We have coinsurance with funds withheld reinsurance agreements in which we cede our U.S. retail fixed annuity and ULSG blocks of business using both the reinsurance and deposit methods of accounting.

We are contingently liable with respect to reinsurance ceded to other companies in the event the reinsurer is unable to meet the obligations it has assumed. As of March 31, 2025, and December 31, 2024, we had $14,692.7 million and $14,592.6 million of reinsurance recoverable assets, respectively, included in reinsurance recoverable and deposit receivable on the consolidated statements of financial position, which does not reflect potentially offsetting impacts of collateral. As of March 31, 2025, and December 31, 2024, we had $74.9 million and $60.3 million of reinsurance recoverable liabilities, respectively, included in future policy benefits and claims on the consolidated statements of financial position.

​

As of March 31, 2025 and December 31, 2024, we had a $4,699.9 million and $4,897.5 million reinsurance deposit receivable, respectively.

Refer to Note 4, Investments, for information on our financing receivables valuation allowance related to the reinsurance recoverable and deposit receivable.

Cost of Reinsurance

A reinsurance asset or liability is established to spread the expected net reinsurance costs or profits over the expected term of the contracts. The cost of reinsurance asset and liability are reported in premiums due and other receivables and liability for future policy benefits and claims, respectively, on the consolidated statements of financial position. The cost of reinsurance asset and liability included on the consolidated statements of financial position were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | March 31, 2025 |  | December 31, 2024

Cost of reinsurance asset | ​ | $ | 3,165.9 | ​ | $ | 3,187.6
​ | ​ | ​ | ​ | ​ | ​ | ​
Cost of reinsurance liability | ​ | $ | 956.9 | ​ | $ | 958.1

​

Cost of reinsurance amortization, including the impacts of remeasurement, of $20.0 million and $5.5 million for the three months ended March 31, 2025 and 2024, respectively, was reported in benefits, claims and settlement expenses and liability for future policy benefits remeasurement (gain) loss on the consolidated statements of operations.

​

Certain assets are reported at amortized cost while the fair value of those assets is reflected in the funds withheld payable. As of March 31, 2025 and December 31, 2024, we had a $18,212.3 million and $18,103.7 million funds withheld payable, which was net of a $2,804.8 million and $3,014.5 million embedded derivative asset, respectively. The change in fair value of the embedded derivative was a gain (loss) of $(209.7) million and $197.0 million for the three months ended March 31, 2025 and 2024, respectively.

While the economic benefits of the funds withheld assets flow to the reinsurer, we retain legal ownership of the assets within the funds withheld account. Guidelines are in place to ensure the investment risk is appropriately managed. Net investment income and net realized capital gains (losses) related to the assets on the consolidated statements of operations is reported net of the amounts that flow to the reinsurer. The realized gains and losses that do not flow to the reinsurer are reported in net realized capital gains (losses) on funds withheld assets on the consolidated statements of operations.

Following are the components of net realized capital gains (losses) on the funds withheld assets that were passed to the reinsurer.

Contingent Funding Agreements for Senior Debt Issuance

On March 8, 2018, we entered into two contingent funding agreements: (1) a 10-year contingent funding agreement with a Delaware trust (“2028 Trust”) formed by us in connection with the sale by the trust of $400.0 million pre-capitalized trust securities redeemable February 15, 2028 (“2028 P-Caps”) in a Rule 144A private placement and (2) a 30-year contingent funding agreement with a Delaware trust (“2048 Trust”) formed by us in connection with the sale by the trust of $350.0 million pre-capitalized trust securities redeemable February 15, 2048 (“2048 P-Caps”) in a Rule 144A private placement. The trusts invested the proceeds from the sale of the 2028 P-Caps and 2048 P-Caps in a portfolio of principal and interest strips of U.S. Treasury securities. The contingent funding agreements provide us a put option that gives us the right to sell at any time: (1) to the 2028 Trust up to $400.0 million of its 4.111% Senior Notes due 2028 (“4.111% Senior Notes”) and (2) to the 2048 Trust up to $350.0 million of its 4.682% Senior Notes due 2048 (“4.682% Senior Notes”) and receive in exchange a corresponding amount of the principal and interest strips of U.S. Treasury securities held by the trusts (“Eligible Assets”). The 4.682% Senior Notes will not be issued unless and until a put option is exercised, while the put option for the 4.111% Senior Notes was exercised on March 19, 2025. We agreed to pay a semi-annual put premium of 1.275% and 1.580% per annum on the unexercised portion of the put option to the 2028 Trust and 2048 Trust, respectively, and to reimburse the trusts for expenses. The put option premiums are recorded in operating expenses in the consolidated statements of operations. The 4.111% Senior Notes and 4.682% Senior Notes will be fully, irrevocably and unconditionally guaranteed by Principal Financial Services, Inc. (“PFS”). In addition, our obligations under the put option agreement and the expense reimbursement agreement with the trusts are also guaranteed by PFS. The contingent funding agreements with the trusts provide us with a source of liquid assets, which could be used to meet future financial obligations or to provide additional capital.

On March 19, 2025, we completed the exercise of our rights in full under the put option with the 2028 Trust in exchange for the Eligible Assets (the “2028 P - Caps Exercise”). In connection with the exercise of our put options right, we (1) issued $400.0 million of 4.111% Senior Notes due 2028 (“2028 Notes”) to the 2028 Trust (2) waived our rights to repurchase the 2028 Notes and (3) directed The Bank of New York Mellon to dissolve the 2028 Trust in accordance with its declaration of trust and deliver the 2028 Notes to the beneficial holders of the 2028 P-Caps pro rata in respect of each 2028 P-Cap. We intend to use the proceeds from the 2028 P-Caps Exercise to redeem or repay at or prior to maturity all $400.0 million aggregate principal amount outstanding of our 3.400% senior notes that mature on May 15, 2025 (the “2025 Notes”), in accordance with the terms of the indenture governing the 2025 Notes.

In addition, on March 6, 2025, we entered into a 30-year contingent funding agreement with a Delaware trust (“2055 Trust”) formed by us in connection with the sale by the trust of $500.0 million pre-capitalized trust securities redeemable February 15, 2055 (“2055 P-Caps”) in a Rule 144A private placement. The trusts invested the proceeds from the sale of the 2055 P-Caps in a portfolio of principal and interest strips of U.S. Treasury securities. The contingent funding agreements provide us the right to sell at any time to the 2055 Trust up to $500.0 million of its 5.807% Senior Notes due 2055 (“5.807% Senior Notes”) and receive in exchange a corresponding amount of the principal and interest strips of U.S. Treasury securities held by the trusts. The 5.807% Senior Notes will not be issued unless and until we exercise our issuance right. We agreed to pay a semi-annual facility fee of 1.289% per annum on the unexercised portion of the contingent fund mechanism to the 2055 Trust (the “facility agreement”), respectively, and to reimburse the trusts for expenses. The facility fee paid under the facility agreement is recorded in operating expenses in the consolidated statements of operations. The 5.807% Senior Notes will be fully, irrevocably and unconditionally guaranteed by PFS. In addition, our obligations under the facility agreement and the expense reimbursement agreement with the trusts are also guaranteed by PFS.

Pillar Two Model Rules

​

We are currently monitoring global enactments of the Pillar Two model rules proposed by the Organisation for Economic Co-operation and Development, which brings forward a 15% global minimum tax. Generally, a company is required to consider the impact of new tax law on realizability of its deferred tax assets (“DTAs”), including determination of whether a change to its valuation allowance amounts is necessary. We made an accounting policy election to disregard the Pillar Two model rules when evaluating DTAs and rather recognize a current period tax expense when incurred.

Contributions

Our funding policy for our qualified pension plan is to fund the plan annually in an amount at least equal to the minimum annual contribution required under the Employee Retirement Income Security Act (“ERISA”) and, generally, not greater than the maximum amount that can be deducted for U.S. federal income tax purposes. We do not anticipate contributions will be needed to satisfy the minimum funding requirements of ERISA for our qualified plan in 2025; however, it is possible that we may fund both the qualified and nonqualified pension plans in 2025 for a combined total of up to $70.0 million. During the three months ended March 31, 2025, we did not contribute to these plans.

​

15. Contingencies, Guarantees and Indemnifications

Litigation and Regulatory Contingencies

We are regularly involved in litigation, both as a defendant and as a plaintiff, but primarily as a defendant. Litigation naming us as a defendant ordinarily arises out of our business operations as a provider of asset management and accumulation products and services, individual life insurance, specialty benefits insurance and our investment activities. Some of the lawsuits may be class actions, or purport to be, and some may include claims for unspecified or substantial punitive and treble damages.

We may discuss such litigation in one of three ways. We accrue a charge to income and disclose legal matters for which the chance of loss is probable and for which the amount of loss can be reasonably estimated. We may disclose contingencies for which the chance of loss is reasonably possible and provide an estimate of the possible loss or range of loss or a statement that such an estimate cannot be made. Finally, we may voluntarily disclose loss contingencies for which the chance of loss is remote in order to provide information concerning matters that potentially expose us to possible losses.

In addition, regulatory bodies such as state insurance departments, the SEC, the Financial Industry Regulatory Authority (“FINRA”), the Department of Labor (“DOL”) and other regulatory agencies in the U.S. and in international locations in which we do business, regularly make inquiries and conduct examinations or investigations concerning our compliance with, among other things, insurance laws, securities laws, ERISA and laws governing the activities of broker-dealers. We receive requests from regulators and other governmental authorities relating to industry issues and may receive additional requests, including subpoenas and interrogatories, in the future.

While the outcome of any pending or future litigation or regulatory matter cannot be predicted, management does not believe any such matter will have a material adverse effect on our business or financial position. To the extent such matters present a reasonably possible chance of loss, we are generally not able to estimate the possible loss or range of loss associated therewith. The outcome of such matters is always uncertain and unforeseen results can occur. It is possible that such outcomes could require us to pay damages or make other expenditures or establish accruals in amounts that we could not estimate as of March 31, 2025.

Guarantees and Indemnifications

In the normal course of business, we have provided guarantees to third parties primarily related to former subsidiaries and joint ventures. The terms of these agreements range in duration and often are not explicitly defined. The maximum exposure under these agreements as of March 31, 2025, was approximately $77.0 million. At inception, the fair value of such guarantees was insignificant. In addition, we believe the likelihood is remote that material payments will be required. Therefore, any liability accrued within our consolidated statements of financial position is insignificant. Should we be required to perform under these guarantees, we generally could recover a portion of the loss from third parties through recourse provisions included in agreements with such parties, the sale of assets held as collateral that can be liquidated in the event performance is required under the guarantees or other recourse generally available to us; therefore, such guarantees would not result in a material adverse effect on our business or financial position. While the likelihood is remote, such outcomes could materially affect net income in a particular quarter or annual period. Furthermore, in connection with our contingent funding agreements, we are required to purchase any principal and interest strips of U.S. Treasury securities that are due and not paid from the associated unconsolidated trusts. The maximum exposure under these agreements as of March 31, 2025, was $850.0 million. See Note 12, Long-Term Debt, for further details.

We manage mandatory privatized social security funds in Chile. By regulation, we have a required minimum guarantee on the funds’ relative return. Because the guarantee has no limitation with respect to duration or amount, the maximum exposure of the guarantee in the future is indeterminable.

We are also subject to various other indemnification obligations issued in conjunction with divestitures, acquisitions, financing and reinsurance transactions whose terms range in duration and often are not explicitly defined. Certain portions of these indemnifications may be capped, while other portions are not subject to such limitations; therefore, the overall maximum amount of the obligation under the indemnifications cannot be reasonably estimated. At inception, the fair value of such indemnifications was insignificant. In addition, we believe the likelihood is remote that material payments will be required. Therefore, any liability accrued within our consolidated statements of financial position is insignificant. While we are unable to estimate with certainty the ultimate legal and financial liability with respect to these indemnifications, we believe that performance under these indemnifications would not result in a material adverse effect on our business or financial position. While the likelihood is remote, performance under these indemnifications could materially affect net income in a particular quarter or annual period.

​

Noncontrolling Interest

Interests held by unaffiliated parties in consolidated entities are reflected in noncontrolling interest, which represents the noncontrolling partners’ share of the underlying net assets of our consolidated subsidiaries. Noncontrolling interest that is not redeemable is reported in the equity section of the consolidated statements of financial position.

The noncontrolling interest holders in certain of our consolidated entities maintain an equity interest that is redeemable at the option of the holder, which may be exercised on varying dates. Since redemption of the noncontrolling interest is outside of our control, this interest is excluded from stockholders’ equity and reported separately as redeemable noncontrolling interest on the consolidated statements of financial position. Our redeemable noncontrolling interest primarily relates to consolidated sponsored investment funds for which interests are redeemed at fair value from the net assets of the funds.

For our redeemable noncontrolling interest related to other consolidated subsidiaries, redemptions are required to be purchased at fair value or a value based on a formula that management intended to reasonably approximate fair value based on a fixed multiple of earnings over a measurement period. The carrying value of the redeemable noncontrolling interest is compared to the redemption value at each reporting period. Any adjustments to the carrying amount of the redeemable noncontrolling interest for changes in redemption value prior to exercise of the redemption option are determined after the attribution of net income or loss of the subsidiary and are recognized in the redemption value as they occur. Adjustments to the carrying value of redeemable noncontrolling interest result in adjustments to additional paid-in capital and/or retained earnings. Adjustments are recorded in retained earnings to the extent the redemption value of the redeemable noncontrolling interest exceeds its fair value and will impact the numerator in our earnings per share calculations. All other adjustments to the redeemable noncontrolling interest are recorded in additional paid-in capital.

17. Fair Value Measurements

We use fair value measurements to record fair value of certain assets and liabilities and to estimate fair value of financial instruments not recorded at fair value but required to be disclosed at fair value. Certain financial instruments, particularly policyholder liabilities other than investment contracts, are excluded from these fair value disclosure requirements.

Valuation Hierarchy

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety considering factors specific to the asset or liability.

● | Level 1 – Fair values are based on unadjusted quoted prices in active markets for identical assets or liabilities.

● | Level 2 – Fair values are based on inputs other than quoted prices within Level 1 that are observable for the asset or liability, either directly or indirectly.

● | Level 3 – Fair values are based on at least one significant unobservable input for the asset or liability.

Determination of Fair Value

The following discussion describes the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis. The techniques utilized in estimating the fair value of financial instruments are reliant on the assumptions used. Care should be exercised in deriving conclusions about our business, its value or financial position based on the fair value information of financial instruments presented below.

Fair value estimates are made based on available market information and judgments about the financial instrument at a specific point in time. Such estimates do not consider the tax impact of the realization of unrealized gains or losses. In addition, the disclosed fair value may not be realized in the immediate settlement of the financial instrument. We validate prices through an investment analyst review process, which includes validation through direct interaction with external sources, review of recent trade activity or use of internal models. In circumstances where broker quotes are used to value an instrument, we generally receive one non-binding quote. Broker quotes are validated through an investment analyst review process, which includes validation through direct interaction with external sources and use of internal models or other relevant information. We did not make any significant changes to our valuation processes during 2025.

Fixed Maturities

Fixed maturities include bonds, ABS, redeemable preferred stock and certain non-redeemable preferred securities. When available, the fair value of fixed maturities is based on quoted prices of identical assets in active markets. These are reflected in Level 1 and primarily include U.S. Treasury bonds and actively traded redeemable corporate preferred securities.

When quoted prices of identical assets in active markets are not available, our first priority is to obtain prices from third party pricing vendors. We have regular interaction with these vendors to ensure we understand their pricing methodologies and to confirm they are utilizing observable market information. Their methodologies vary by asset class and include inputs such as estimated cash flows, benchmark yields, reported trades, broker quotes, credit quality, industry events and economic events. Fixed maturities with validated prices from pricing services, which includes the majority of our public fixed maturities in all asset classes, are generally reflected in Level 2. Also included in Level 2 are corporate bonds when quoted market prices are not available, for which an internal model using substantially all observable inputs or a matrix pricing valuation approach is used. In the matrix approach, securities are grouped into pricing categories that vary by sector, rating and average life. Each pricing category is assigned a risk spread based on studies of observable public market data for specific security classes. The expected cash flows of the security are then discounted back at the current Treasury curve plus the appropriate risk spread. Although the matrix valuation approach provides a fair valuation of each pricing category, the valuation of an individual security within each pricing category may also be impacted by company specific factors.

If we are unable to price a fixed maturity security using prices from third party pricing vendors or other sources specific to the asset class, we may obtain a broker quote or utilize an internal pricing model specific to the asset utilizing relevant market information, to the extent available and where at least one significant unobservable input is utilized. These are reflected in Level 3 in the fair value hierarchy and can include fixed maturities across all asset classes. As of March 31, 2025, approximately 3% of our total fixed maturities were Level 3 securities valued using internal pricing models.

The primary inputs, by asset class, for valuations of the majority of our Level 2 investments from third party pricing vendors or our internal pricing valuation approach are described below.

U.S. Government and Agencies/Non-U.S. Governments. Inputs include recently executed market transactions, interest rate yield curves, maturity dates, market price quotations and credit spreads relating to similar instruments.

States and Political Subdivisions. Inputs include Municipal Securities Rulemaking Board reported trades, U.S. Treasury and other benchmark curves, material event notices, new issue data and obligor credit ratings.

Corporate. Inputs include recently executed transactions, market price quotations, benchmark yields, issuer spreads and observations of equity and credit default swap curves related to the issuer. For private placement corporate securities valued through the matrix valuation approach inputs include the current Treasury curve and risk spreads based on sector, rating and average life of the issuance.

RMBS, CMBS, Collateralized Debt Obligations and Other Debt Obligations.

Equity Securities

Equity securities include mutual funds, common stock, non-redeemable preferred stock and required regulatory investments. Fair values of equity securities are determined using quoted prices in active markets for identical assets when available, which are reflected in Level 1. When quoted prices are not available, we may utilize internal valuation methodologies appropriate for the specific asset that use observable inputs such as underlying share prices or the NAV, which are reflected in Level 2. Fair values might also be determined using broker quotes or through the use of internal models or analysis that incorporate significant assumptions deemed appropriate given the circumstances and consistent with what other market participants would use when pricing such securities, which are reflected in Level 3.

Mortgage Loans

Mortgage loans reported at fair value included those of a consolidated VIE for which the fair value option was elected. Fair values of commercial mortgage loans were primarily determined by discounting the expected cash flows at current treasury rates plus an applicable risk spread, which reflected credit quality and maturity of the loans. The risk spread was based on market clearing levels for loans with comparable credit quality, maturities and risk. These were reflected in Level 3. Mortgage loans valued using securitized pricing based on observable market data should be reflected in Level 2 of the fair value hierarchy. The consolidated VIE was deconsolidated during 2025.

Derivatives

The fair values of exchange-traded derivatives are determined through quoted market prices, which are reflected in Level 1. Exchange-traded derivatives include futures that are settled daily, which reduces their fair value in the consolidated statements of financial position. The fair values of OTC cleared derivatives are determined through market prices published by the clearinghouses, which are reflected in Level 2. The clearinghouses utilize the secured overnight financing rate (“SOFR”) curve in their valuation. Variation margin associated with OTC cleared derivatives is settled daily, which reduces their fair value in the consolidated statements of financial position. The fair values of bilateral OTC derivative instruments are determined using either pricing valuation models that utilize market observable inputs or broker quotes. The majority of our bilateral OTC derivatives are valued with models that use market observable inputs, which are reflected in Level 2. Significant inputs include contractual terms, interest rates, currency exchange rates, credit spread curves, equity prices and volatilities. These valuation models consider projected discounted cash flows, relevant swap curves and appropriate implied volatilities. Certain bilateral OTC derivatives utilize unobservable market data, primarily independent broker quotes that are nonbinding quotes based on models that do not reflect the result of market transactions, which are reflected in Level 3.

Our non-cleared derivative contracts are generally documented under ISDA Master Agreements, which provide for legally enforceable set-off and close-out netting of exposures to specific counterparties. Collateral arrangements are bilateral and based on current ratings of each entity. We utilize the SOFR curve to value our positions. Counterparty credit risk is routinely monitored to ensure our adjustment for nonperformance risk is appropriate. Our centrally cleared derivative contracts are conducted with regulated centralized clearinghouses, which provide for daily exchange of cash collateral or variation margin equal to the difference in the daily market values of those contracts that eliminates the nonperformance risk on these trades.

Interest Rate Contracts. For non-cleared contracts, which include interest rate swaps and interest rate options, we use discounted cash flow valuation techniques to determine the fair value using observable swap curves as the inputs. These are reflected in Level 2. We have forward contracts for which we obtain prices from third party pricing vendors. These are reflected in Level 2. For centrally cleared contracts we use published prices from clearinghouses. These are reflected in Level 2. In addition, we have forward contracts that are valued using broker quotes. These are reflected in Level 3.

Foreign Exchange Contracts. We use discounted cash flow valuation techniques that utilize observable swap curves and exchange rates as the inputs to determine the fair value of foreign currency swaps. These are reflected in Level 2. Currency forwards are valued using observable market inputs, including forward currency exchange rates. These are reflected in Level 2. In addition, we had a limited number of non-standard currency swaps that were valued using broker quotes. These were reflected within Level 3.

Equity Contracts. We use an option pricing model using observable implied volatilities, dividend yields, index prices and swap curves as the inputs to determine the fair value of equity options. Certain total return swaps use an accrual method comparing both cash flows to determine fair value. These are reflected in Level 2. Certain equity option contracts are valued using broker quotes. These are reflected in Level 3.

Credit Contracts. We use either the ISDA Credit Default Swap Standard discounted cash flow model that utilizes observable default probabilities and recovery rates as inputs to determine the fair value of credit default swaps. These are reflected in Level 2. In addition, we have total return swaps and a limited number of credit default swaps that are valued using broker quotes. These are reflected within Level 3.

Other Investments

Other investments reported at fair value include invested assets of consolidated sponsored investment funds, unconsolidated sponsored investment funds, other investment funds reported at fair value, other loans of a consolidated VIE for which the fair value option was elected and certain redeemable and nonredeemable preferred stock.

Invested assets of consolidated sponsored investment funds include equity securities, fixed maturities and derivative assets, for which fair values are determined as previously described, and are reflected in Level 1 and Level 2.

The fair value of unconsolidated sponsored investment funds and other investment funds is determined using the NAV of the fund. The NAV of the fund represents the price at which we would be able to initiate a transaction. Investments for which the NAV represents a quoted price in an active market for identical assets are reflected in Level 1. Investments that do not have a quoted price in an active market are reflected in Level 2.

Other loans of a consolidated VIE for which the fair value option was elected are reflected in Level 3. The fair value of these loans is estimated using a discounted cash flow valuation model that utilizes standard assumption-setting methodology accepted by market participants in the industry. The assumptions are formed based on historical performance of the loans and utilizes market data inputs such as charge-off rates, prepayment rates, recovery rates and discount rates.

Cash Equivalents

Certain cash equivalents are reported at fair value on a recurring basis and include money market instruments and other short-term investments with maturities of three months or less. Fair values of these cash equivalents may be determined using public quotations, when available, which are reflected in Level 1. When public quotations are not available, because of the highly liquid nature of these assets, carrying amounts may be used to approximate fair values, which are reflected in Level 2.

Separate Account Assets

Separate account assets include equity securities, debt securities, cash equivalents and derivative instruments, for which fair values are determined as previously described, and are reflected in Level 1, Level 2 and Level 3. Separate account assets also include commercial mortgage loans, for which the fair value is estimated by discounting the expected total cash flows using market rates that are applicable to the yield, credit quality and maturity of the loans. The market clearing spreads vary based on mortgage type, weighted average life, rating and liquidity. These are reflected in Level 3. Finally, separate account assets include real estate, for which the fair value is estimated using discounted cash flow valuation models that utilize various public real estate market data inputs. In addition, each property is appraised annually by an independent appraiser. The real estate included in separate account assets is recorded net of related mortgage encumbrances for which the fair value is estimated using discounted cash flow analysis based on our incremental borrowing rate for similar borrowing arrangements. The real estate within the separate accounts is reflected in Level 3.

Market Risk Benefits

MRBs are measured at fair value at the contract level on a recurring basis and are reflected in Level 3 as either an asset or a liability, depending on certain inputs at the reporting date. The key assumptions for calculating the fair value are market assumptions and policyholder behavior. Risk margins are included in the policyholder behavior assumptions. The assumptions are based on a combination of historical data and actuarial judgment. The MRBs are valued using stochastic models that incorporate a spread reflecting our own nonperformance risk.

The assumption for our own nonperformance risk is based on current market credit spreads for debt-like instruments we have issued and are available in the market. Refer to Note 10, Market Risk Benefits, for further information on the determination of fair value measurement of MRBs.

Investment and Universal Life Contracts

Certain universal life, annuity and other investment contracts include embedded derivatives that have been bifurcated from the host contract and are measured at fair value on a recurring basis, which are reflected in Level 3. The key assumptions for calculating the fair value of the embedded derivative liabilities are market assumptions (such as equity market returns, interest rate levels, market volatility and correlations) and policyholder behavior assumptions (such as lapse and mortality). Risk margins are included in the policyholder behavior assumptions. The assumptions are based on a combination of historical data and actuarial judgment. The embedded derivative liabilities are valued using models that incorporate a spread reflecting our own creditworthiness.

The assumption for our own nonperformance risk for investment contracts and any embedded derivatives bifurcated from certain universal life, annuity and investment contracts is based on the current market credit spreads for debt-like instruments we have issued and are available in the market.

Funds Withheld Payable

The funds withheld payable includes an embedded derivative that has been bifurcated from the host contract and is measured at fair value on a recurring basis, which is reflected in Level 3. The fair value is determined based on the change in the estimated fair value of the underlying funds withheld investments. The fair value of these assets is determined as previously described.

Long-Term Debt

Long-term debt reported at fair value included that of a consolidated VIE for which the fair value option was elected. The long-term debt was a secured credit facility that was primarily financing for commercial real estate loans. The fair value was estimated using discounted cash flow analysis based on our incremental borrowing rate for similar borrowing arrangements. These were reflected in Level 2. The consolidated VIE was deconsolidated during 2025.

Other Liabilities

Derivative liabilities of consolidated sponsored investment funds are reported at fair value within other liabilities. Fair values of these derivatives are determined as previously described and are reflected in Level 1 and Level 2.

Assets transferred into Level 3 during the three months ended March 31, 2024, primarily included those assets for which we are now unable to obtain pricing from a recognized third party pricing vendor as well as assets that were previously priced using a matrix valuation approach that may no longer be relevant when applied to asset-specific situations.

Assets transferred out of Level 3 during the three months ended March 31, 2025 and 2024, primarily included those assets for which we are now able to obtain pricing from a recognized third party pricing vendor or from internal models using substantially all market observable information.

Quantitative Information about Level 3 Fair Value Measurements

The following table provides quantitative information about the significant unobservable inputs used for recurring fair value measurements categorized within Level 3, excluding assets and liabilities for which significant quantitative unobservable inputs are not developed internally, which primarily consists of those valued using broker quotes. The MRB asset and liability are excluded from the table. Refer to Note 10, Market Risk Benefits, for information on the unobservable inputs used for fair value measurement of MRBs. The funds withheld payable embedded derivative is excluded from the table as the determination of its fair value incorporates the fair value of the invested assets supporting the reinsurance agreement. The commercial mortgage loans of a consolidated VIE are excluded from the table as the determination of fair value was based on transaction price due to proximity of purchase to year - end, and thus no inputs to be provided. Refer to “Assets and liabilities measured at fair value on a recurring basis” for a complete valuation hierarchy summary.

Market comparable discount rates are used as the base rate in the discounted cash flows used to determine the fair value of certain assets. The use of a higher or lower discount rate would have caused the fair value of the assets to significantly decrease or increase, respectively. Additionally, we may adjust the base discount rate or the modeled price by applying an illiquidity premium given the highly structured nature of certain assets. The use of a higher or lower illiquidity premium would have caused significant decreases or increases, respectively, in the fair value of the asset.

Embedded derivatives within our investment and universal life contracts liability can be in either an asset or liability position, depending on certain inputs at the reporting date. Increases to an asset or decreases to a liability are described as increases to fair value. The use of a higher or lower market volatility would have caused significant decreases or increases, respectively, in the fair value of embedded derivatives in investment and universal life contracts. Long duration interest rates are used as the mean return when projecting the growth in the value of associated account value and impact the discount rate used in the discounted future cash flows valuation. The use of higher or lower risk-free rates would have caused the fair value of the embedded derivative to significantly increase or decrease, respectively. The use of a higher or lower rate for our own credit risks, which impact the rates used to discount future cash flows, would have significantly increased or decreased, respectively, the fair value of the embedded derivative. The use of a lower or higher mortality rate assumption would have caused the fair value of the embedded derivative to decrease or increase, respectively. The use of a lower or higher overall lapse rate assumption would have caused the fair value of the embedded derivative to decrease or increase, respectively.

​

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

No significant assets and liabilities were measured at fair value on a nonrecurring basis for the three months ended March 31, 2025 and 2024.

Fair Value Option

We elected fair value accounting for:

| ● | Certain other loans of a consolidated VIE that were subject to amortized cost accounting and a valuation allowance so that credit losses are recognized within the changes in fair value in the consolidated statements of operations.

| ● | Certain mortgage loans and long-term debt of a consolidated VIE to provide alignment between the consolidated VIE’s financial reporting and the calculation of net asset value per share used to determine the prices at which investors could purchase and redeem shares of the entity’s stock. The consolidated VIE was deconsolidated during 2025.

18. Segment Information

We provide financial products and services through the following segments: Retirement and Income Solutions, Principal Asset Management and Benefits and Protection. In addition, we have a Corporate segment. The segments are managed and reported separately because they provide different products and services, have different strategies or have different markets and distribution channels.

The Retirement and Income Solutions segment provides retirement and related financial products and services primarily to businesses, their employees and other individuals. The segment includes workplace savings and retirement solutions, banking, trust and custodial services, individual variable annuities (including RILAs), pension risk transfer, investment only and our exited retail fixed annuities business.

The Principal Asset Management segment provides global investment solutions to institutional, retirement, retail and high net worth investors in the U.S. and select emerging markets. The segment is organized into Investment Management, which provides public, multi-asset and private market capabilities across all asset classes, including equity, fixed income, real estate and alternatives, to serve a breadth of client investment objectives; and International Pension, which provides long-term savings and retirement solutions through pension accumulation and income annuities in Asia and Latin America.

The Benefits and Protection segment focuses on solutions primarily for small-to-mid sized businesses and their employees. The segment is organized into Specialty Benefits, which provides group dental, group life insurance, group disability insurance (including short-term disability, long-term disability and paid family and medical leave), supplemental health products (including vision, critical illness, accident and hospital indemnity) and individual disability insurance; and Life Insurance, which provides life insurance focused on the business market customer, including universal life and variable universal life (including indexed universal life) and traditional life insurance (including term life insurance). All remaining customers are part of the legacy life block of business, including universal and variable universal life insurance (including indexed universal life), traditional life insurance (including participating whole life, adjustable life products and term life insurance) and our exited ULSG business.

Our Corporate segment manages the assets representing capital that has not been allocated to any other segment. Financial results of the Corporate segment primarily reflect our financing activities (including financing costs), income on capital not allocated to other segments, inter-segment eliminations, income tax risks and certain income, expenses and other adjustments not allocated to the segments based on the nature of such items. Results of Principal Securities, Inc. (“PSI”), our retail broker-dealer and registered investment advisor (“RIA”); and our exited group medical and long-term care insurance businesses are reported in this segment.

Our chief operating decision maker (“CODM”) is our chief executive officer. Our CODM and management team, use segment pre-tax operating earnings in evaluating performance, which is consistent with the financial results provided to and discussed with securities analysts. In addition, the financial information provided to our CODM is used in making decisions about the allocation of resources and determining annual incentive compensation paid to our employees. We determine segment pre-tax operating earnings by adjusting U.S. GAAP income before income taxes for pre-tax net realized capital gains (losses), as adjusted, pre-tax income (loss) from exited business, pre-tax other adjustments that management believes are not indicative of overall operating trends and certain adjustments related to equity method investments and noncontrolling interest. While these items may be significant components in understanding and assessing the consolidated financial performance, management believes the presentation of pre-tax operating earnings enhances the understanding of our results of operations by highlighting pre-tax earnings attributable to the normal, ongoing operations of the business.

The pre-tax net realized capital gains (losses), as adjusted, excluded from pre-tax operating earnings reflects consolidated U.S. GAAP pre-tax net realized capital gains (losses) excluding the following items that are included in pre-tax operating earnings:

| ● | Periodic settlements and accruals on derivative instruments not designated as hedging instruments,

| ● | Certain market value adjustments of derivatives and embedded derivatives and

| ● | Certain market value adjustments of derivative instruments used to economically hedge embedded derivatives.

Pre-tax net realized capital gains (losses), as adjusted, are further adjusted for:

| ● | Amortization of hedge accounting book value adjustments for certain discontinued hedges,

| ● | Certain hedge accounting market value revenue adjustments,

| ● | Certain market value adjustments to fee revenues,

| ● | Pre-tax net realized capital gains (losses) related to equity method investments,

| ● | Pre-tax net realized capital gains (losses) related to sponsored investment funds and other adjustments,

| ● | Certain variable annuity fees,

| ● | Market value adjustments of market risk benefits,

| ● | Related changes in the amortization pattern of actuarial balances,

| ● | Certain hedge accounting market value expense adjustments and

| ● | Net realized capital gains (losses) distributed.

Pre-tax income (loss) from exited business includes amounts associated with our exited U.S. retail fixed annuity and ULSG businesses as well as amounts associated with other exited or divested businesses. Pre-tax income (loss) from exited business includes the change in fair value of the funds withheld embedded derivative, net realized capital gains (losses) on funds withheld assets, amortization of reinsurance gain (loss) and other impacts of exited business. Other impacts of exited business primarily includes change in reserves and DAC amortization. Other impacts of exited business in 2025 also include the impairment of assets associated with an exited business.

Segment operating revenues reflect consolidated U.S. GAAP total revenues excluding:

| ● | Net realized capital gains (losses), except periodic settlements and accruals on derivatives not designated as hedging instruments and certain market value adjustments of derivative instruments used to economically hedge embedded derivatives, and their impact on:

| ● | Amortization of hedge accounting book value adjustments for certain discontinued hedges,

| ● | Certain hedge accounting market value revenue adjustments,

| ● | Certain variable annuity fees,

| ● | Certain market value adjustments to fee revenues,

| ● | Pre-tax net realized capital gains (losses) related to equity method investments and

| ● | Pre-tax net realized capital gains (losses) related to sponsored investment funds and other adjustments.

| ● | Pre-tax revenues from exited business,

| ● | Pre-tax other revenue adjustments and income taxes of equity method investments and

| ● | Pre-tax other revenue adjustments management believes are not indicative of overall operating trends.

Segment expenses reflect consolidated U.S. GAAP total expenses excluding:

| ● | Pre-tax expenses associated with net realized capital gains (losses),

| ● | Periodic settlements and accruals on derivatives used to hedge MRBs,

| ● | Pre-tax expenses from exited business and

| ● | Pre-tax expense adjustments management believes are not indicative of overall operating trends.

​

The accounting policies of the segments are consistent with the accounting policies for the consolidated financial statements, with the exception of: (1) pension and other postretirement employee benefits cost allocations, (2) certain expenses deemed to benefit the entire organization and (3) income tax allocations. For purposes of determining pre-tax operating earnings, the segments are allocated the service component of pension and other postretirement benefit costs. The Corporate segment reflects the non-service components of pension and other postretirement benefit costs as assumptions are established and funding decisions are managed from a company-wide perspective. Additionally, the Corporate segment reflects expenses that benefit the entire organization for which the segments are not able to influence the spend. This includes expenses such as public company costs, executive management costs, acquisition and disposition costs, among others. The Corporate segment functions to absorb the risk inherent in interpreting and applying tax law. For purposes of determining non-GAAP operating earnings, the segments are allocated tax adjustments consistent with the positions we took on tax returns. The Corporate segment results reflect any differences between the tax returns and the estimated resolution of any disputes.

Retirement and Income Solutions

Retirement and Income Solutions offers service and trust agreements for defined contribution retirement plans, including 401(k) plans, 403(b) plans, and employee stock ownership plans. The investment components of these service agreements are in the form of mutual fund offerings. In addition, plan sponsor retirement plan trust and custody services are also available through our trust company. Individual retirement accounts (“IRAs”) are offered through Principal Bank. Furthermore, services and trust agreements are offered to non-retirement customers including insurance companies, endowments and other financial institutions.

Administrative service fee revenues are earned for administrative activities performed for the defined contribution retirement plans including recordkeeping and reporting as well as trust and custody, asset management and investment services. Administrative service fee revenues are earned for administrative activities performed for non-retirement plan customers including trust and custody services, defined benefit administration and investment management activities. The majority of these activities are performed daily over time. Fee-for-service transactions are also provided upon client request. These services are considered distinct or grouped into a bundle until a distinct performance obligation is identified. Some performance obligations are considered a series of distinct services, which are substantially the same and have the same pattern of transfer to the customer.

Administrative service fee revenues can be based on a fixed contractual rate for these services or can be variable based upon contractual rates applied to the market value of the client’s investments or assets under administration. If the consideration for this series of performance obligations is based on market value, it is considered variable during the billing period as the services are performed over time. The consideration becomes unconstrained and thus recognized as revenue for each billing period’s series of distinct services once the market value of the client’s investments or assets under administration is determined at market close. Additionally, fixed fees and other revenues are recognized point-in-time as fee-for-service transactions upon completion.

IRAs are primarily funded by retirement savings rolled over from qualified retirement plans. The IRAs are held in savings accounts, money market accounts and certificates of deposit. Deposit account fee revenues are earned as the performance of establishing and maintaining IRA accounts is completed. Fee-for-service transactions are also provided upon client request. The establishment fees and annual maintenance fees are accrued into earnings over a period of time using the average account life. Upfront and recurring bank fees are related to performance obligations that have the same pattern of transfer to the customer and are recognized in income over time with control transferred to the customers utilizing the output method. These fees are based on a fixed contractual rate. Fixed fees and other revenues are also recognized point-in-time as fee-for-service transactions upon completion. Additionally, commission income is earned on advisory services provided to customers. The revenues are earned over time as the service is performed based upon contractual rates applied to the market value of the clients’ portfolios.

The types of revenues from contracts with customers were as follows:

​

Principal Asset Management

Fees and other revenues earned for asset management, investment advisory and distribution services provided to institutional and retail clients in addition to trustee and/or administrative services performed for retirement savings plans. Fees are based largely upon contractual rates applied to the specified amounts of the clients’ portfolios. Each service is a distinct performance obligation; however, if the services are not distinct on their own, we combine them into a distinct bundle or we have a series of distinct services that are substantially the same and have the same pattern of transfer to the customer. Fees and other revenues received for performance obligations such as asset management and other services are typically recognized over time utilizing the output method as the service is performed. Performance fees and transaction fees on certain accounts are recognized in income when the probability of significant reversal will not occur upon resolution of the uncertainty, which could be based on a variety of factors such as market performance or other internal metrics. Asset management fees are accrued each month based on the fee terms within the applicable agreement and are generally billed quarterly when values used for the calculation are available. Management fees and performance fees are variable consideration as they are subject to fluctuation based on assets under management (“AUM”) and other constraints. These fees are not recognized until unconstrained at the end of each reporting period.

Incentive-based fees are recognized in income when the probability of significant reversal will not occur upon the resolution of the uncertainty, which is based on market performance.

Benefits and Protection

Fees and other revenues are earned for administrative services performed including recordkeeping and reporting services for fee-for-service products, nonqualified benefit plans, separate accounts and dental networks. Services within contracts are not distinct on their own; however, we combine the services into a distinct bundle and account for the bundle as a single performance obligation, which is satisfied over time utilizing the output method as services are rendered. The transaction price corresponds with the performance completed to date, for which the value is recognized as revenue during the period. Variability of consideration is resolved at the end of each period and payments are due when billed.

Commission income is earned through sponsored brokerage services. Performance obligations are satisfied at a point in time, upon delivery of a placed case, and the transaction price calculated per the compensation schedule is recognized as revenue.

Corporate

Fees and other revenues are earned on the performance of selling and servicing of securities and related products offered through PSI, an introducing broker-dealer registered with the FINRA.

PSI enters into selling and distribution agreements with the obligation to sell or distribute the securities products, such as mutual funds, annuities and products sold through RIAs, to individual clients in return for front-end sales charges, 12b-1 service fees, annuity fees and asset-based fees. Front-end sales charges, 12b-1 fees and annuity fees are related to a single sale and are earned at the time of sale. PSI also enters into agreements with individual customers to provide securities trade execution and custody through a brokerage services platform in return for ticket charge and other service fee revenue. These services are bundled as one single distinct service referred to as brokerage services. This revenue is related to distinct transactions and is earned at a point in time.

PSI also enters into agreements with individual customers to provide trade execution, clearing services, custody services and investment research services through our proprietary offered fee-based products. These services are bundled as one single distinct service referred to as advisory services. In addition, for outside RIA business PSI performs sales and distribution services only. The revenues are earned over time as the service is performed utilizing the output method.

A majority of our revenue is based upon contractual rates applied to the market value of the clients’ portfolios and considered variable consideration.

Contract Costs

Sales compensation and other incremental costs of obtaining a contract are capitalized and amortized over the period of contract benefit if the costs are expected to be recovered. The contract cost asset, which is included in other assets on the consolidated statements of financial position, was $158.7 million and $198.9 million as of March 31, 2025 and December 31, 2024, respectively.

We apply the practical expedient for certain costs where we recognize the incremental costs of obtaining these contracts as an expense when incurred if the amortization period of the assets is one year or less. These costs, along with costs that are not deferrable, are included in operating expenses on the consolidated statements of operations.

Deferred contract costs consist primarily of commissions and variable compensation. We amortize capitalized contract costs on a straight-line basis over the expected contract life, reflecting lapses as they are incurred. Deferred contract costs are subject to impairment testing on an annual basis, or when a triggering event occurs that could warrant an impairment. To the extent future revenues less future maintenance expenses are not adequate to cover the asset balance, an impairment is recognized. For the three months ended March 31, 2025 and 2024, $52.8 million and $9.5 million, respectively, of amortization expense was recorded in operating expenses on the consolidated statements of operations. Additionally, for the three months ended March 31, 2025 and 2024, $45.4 million and $0.0 million, respectively, of impairment loss was recognized in operating expenses on the consolidated statements of operations in relation to the costs capitalized. See Note 2, Other Intangible Assets, for further details of the agreement with BCT that led to the 2025 impairment.

20. Stock-Based Compensation Plans

As of March 31, 2025, we had the 2021 Stock Incentive Plan, the 2020 Directors Stock Plan, the 2014 Stock Incentive Plan, the Employee Stock Purchase Plan, the 2014 Directors Stock Plan, the Amended and Restated 2010 Stock Incentive Plan, the 2005 Directors Stock Plan, the Stock Incentive Plan and the Directors Stock Plan (“Stock-Based Compensation Plans”). No new grants will be made under the 2020 Directors Stock Plan, the 2014 Stock Incentive Plan, the 2014 Directors Stock Plan, the Amended and Restated 2010 Stock Incentive Plan, the 2005 Directors Stock Plan, the Stock Incentive Plan or the Directors Stock Plan. Under the terms of the 2021 Stock Incentive Plan, grants may be nonqualified stock options, incentive stock options qualifying under Section 422 of the Internal Revenue Code, restricted stock, restricted stock units, stock appreciation rights, performance shares, performance units or other stock-based awards. To date, we have not granted any incentive stock options, restricted stock or performance units under any plans. As part of our fair value process, we assess the impact of material nonpublic information on our share price or expected volatility, as applicable, at the time of grant. No awards in 2025 required a fair value adjustment.

As of March 31, 2025, the maximum number of new shares of common stock available for grant under the 2021 Stock Incentive Plan was 19.1 million.

For awards with graded vesting, we use an accelerated expense attribution method. The compensation cost that was charged against net income for stock-based awards granted under the Stock-Based Compensation Plans was as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | For the three months ended March 31,
​ |  | 2025 |  | 2024
​ | ​ | (in millions)
Compensation cost | ​ | $ | 39.3 | ​ | $ | 30.6
Related income tax benefit | ​ |  | 9.0 | ​ |  | 7.1
Capitalized as part of an asset | ​ |  | 0.4 | ​ |  | 0.4

​

Nonqualified Stock Options

No nonqualified stock options were granted to employees during both the three months ended March 31, 2025 and 2024. All outstanding nonqualified stock options are vested and have been fully expensed.

Performance Share Awards

Performance share awards were granted to certain employees under the 2021 Stock Incentive Plan. Total performance share awards granted were 0.3 million for the three months ended March 31, 2025. The performance share awards granted represent initial target awards and do not reflect potential increases or decreases resulting from the final performance results to be determined at the end of the performance period. The performance share awards include a relative total shareholder return modifier under which the number of shares ultimately awarded is also impacted by our actual shareholder return relative to our S&P 500 Financial Sector Index peer group. The actual number of common shares to be awarded at the end of each performance period will range between 0% and 180% of the initial target awards. The fair value of performance share awards is determined using a Monte Carlo simulation model. The weighted-average grant date fair value of these performance share awards granted was $90.41 per common share.

As of March 31, 2025, we had $37.9 million of total unrecognized compensation cost related to nonvested performance share awards granted. The cost is expected to be recognized over a weighted-average service period of approximately 1.7 years.

Restricted Stock Units

Restricted stock units were issued to certain employees and non-employee directors pursuant to the 2021 Stock Incentive Plan. Total restricted stock units granted were 1.0 million for the three months ended March 31, 2025. The fair value of restricted stock units is determined based on the closing stock price of our common shares on the grant date. The weighted-average grant date fair value of these restricted stock units granted was $85.10 per common share.

As of March 31, 2025, we had $119.5 million of total unrecognized compensation cost related to nonvested restricted stock unit awards granted. The cost is expected to be recognized over a weighted-average period of approximately 1.9 years.

Employee Stock Purchase Plan

Under the Employee Stock Purchase Plan, employees purchased 0.2 million shares for the three months ended March 31, 2025. The weighted average fair value of the discount on the stock purchased was $8.44 per share.

As of March 31, 2025, a total of 2.4 million of new shares were available to be made issuable by us for this plan.

21. Earnings Per Common Share

The computations of the basic and diluted per share amounts were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | For the three months ended March 31,
​ |  | 2025 |  | 2024
​ | ​ | (in millions, except per share data)
Net income | ​ | $ | 62.9 | ​ | $ | 532.0
Subtract: | ​ | ​ | ​ | ​ | ​ | ​
Net income (loss) attributable to noncontrolling interest | ​ | ​ | 14.8 | ​ | ​ | (0.5)
Total | ​ | $ | 48.1 | ​ | $ | 532.5
Weighted-average shares outstanding: | ​ | ​ | ​ | ​ | ​ | ​
Basic | ​ | ​ | 225.7 | ​ | ​ | 236.0
Dilutive effects: | ​ | ​ | ​ | ​ | ​ | ​
Stock options | ​ | ​ | 0.7 | ​ | ​ | 0.8
Restricted stock units | ​ | ​ | 2.1 | ​ | ​ | 2.2
Performance share awards | ​ | ​ | 0.3 | ​ | ​ | 0.4
Diluted | ​ | ​ | 228.8 | ​ | ​ | 239.4
Net income per common share: | ​ | ​ | ​ | ​ | ​ | ​
Basic | ​ | $ | 0.21 | ​ | $ | 2.26
Diluted | ​ | $ | 0.21 | ​ | $ | 2.22

​

The calculation of diluted earnings per share for the three months ended March 31, 2025 and 2024, excludes the incremental effects related to certain outstanding stock-based compensation grants due to their anti-dilutive effect. When a net loss is reported, our basic weighted-average shares are used to calculate diluted earnings per share, as dilutive shares would have an antidilutive effect and result in a lower loss per share.

Transaction Affecting Comparability of Results of Operations

Principal Mandatory Provident Funds

On January 16, 2025, we announced the signing of an agreement with BCT to expand our investment management capabilities and exit our sponsor and trustee (pension) roles in Hong Kong for MPF Schemes. BCT will be assuming the role as sponsor and trustee for the Principal MPF Schemes. The transaction is expected to close during the first quarter of 2026, subject to regulatory approval; however, certain transaction impacts were recognized in first quarter 2025. We impaired our distribution agreement intangible asset and contract cost asset, resulting in a $65.4 million loss reported in operating expenses on our consolidated statements of operations. Additionally, we classified our customer relationship intangible asset as held-for-sale, resulting in a $77.0 million loss reported in net realized capital gains (losses) on our consolidated statements of operations. For segment reporting, the impairments are reflected in loss from exited business and the held-for-sale write-down is reflected in net realized capital losses. As such, they had no impact on our Principal Asset Management segment pre-tax operating earnings.

Other Factors Affecting Comparability of Results of Operations

Fluctuations in Foreign Currency to U.S. Dollar Exchange Rates

Fluctuations in foreign currency to U.S. dollar exchange rates for locations in which we have operations can affect reported financial results. In years when foreign currencies weaken against the U.S. dollar, translating foreign currencies into U.S. dollars results in fewer U.S. dollars to be reported. When foreign currencies strengthen, translating foreign currencies into U.S. dollars results in more U.S. dollars to be reported.

Foreign currency exchange rate fluctuations create variances in our financial statement line items. The most significant impact occurs within our Principal Asset Management segment where pre-tax operating earnings were negatively impacted $6.0 million for the three months ended March 31, 2025, as a result of fluctuations in foreign currency to U.S. dollar exchange rates. This impact was calculated by comparing (a) the difference between current year results and prior year results to (b) the difference between current year results and prior year results translated using current year exchange rates for both periods. We use this approach to calculate the impact of exchange rates on all revenue and expense line items. For a discussion of our approaches to managing foreign currency exchange rate risk, see Item 3. “Quantitative and Qualitative Disclosures About Market Risk — Foreign Currency Risk.”

Variable Investment Income

Variable investment income includes certain types of investment returns such as prepayment fees and income (loss) from certain elements of our other alternative asset classes, including results of value-add real estate sales activity. Due to its unpredictable nature, variable investment income may or may not be material to our financial results for a given reporting period and may create variances when comparing different reporting periods. For additional information, see “Investment Results.”

​

Three Months Ended March 31, 2025 Compared to Three Months Ended March 31, 2024

Net Income Attributable to Principal Financial Group, Inc.

Net income (loss) attributable to Principal Financial Group, Inc. decreased $321.4 million due to the change in the fair value of the funds withheld embedded derivative and $119.7 million due to the impact from asset write-downs related to exiting our sponsor and trustee (pension) roles in Hong Kong for MPF Schemes.

Total Revenues

Premiums and other considerations increased $44.7 million for the Retirement and Income Solutions segment primarily due to higher sales of single premium group annuities with life contingencies. The single premium group annuity product, which is typically used to fund defined benefit plan terminations, can generate large premiums from very few customers and therefore premiums tend to vary from period to period. Premiums and other considerations increased $22.3 million for the Benefits and Protection segment primarily from growth in our Specialty Benefits business.

Fees and other revenues increased $15.5 million for the Principal Asset Management segment primarily due to higher management fee revenue as a result of increased average AUM managed by our Investment Management operations. Fees and other revenues increased $5.5 million for the Benefits and Protection segment primarily due to growth in our Life Insurance business.

For net investment income and net realized capital gains (losses) variance information, see “Investments — Investment Results” under the captions “Net Investment Income” and “Net Realized Capital Gains (Losses),” respectively.

Net realized capital gains on funds withheld assets decreased due to $38.5 million lower net gains on sales of funds withheld assets as a result of reduced sales in 2025 by an external reinsurer partially offset by a $15.4 million increase due to net unrealized gains on funds withheld assets in 2025 as compared to net unrealized losses in 2024.

114

Table of Contents

The change in the fair value of the funds withheld embedded derivative resulted in a loss in 2025 compared to a gain in 2024 driven by changes in interest rates.

Total Expenses

Benefits, claims and settlement expenses increased $109.2 million for the Retirement and Income Solutions segment primarily due to an increase in reserves, largely stemming from higher sales of single premium group annuities with life contingencies. Benefits, claims and settlement expenses increased for the Benefits and Protection segment primarily due to an $18.3 million increase from growth in our Specialty Benefits business and a $13.9 million increase due to unfavorable claims experience in our Life Insurance business.

The market risk benefit remeasurement (gain) loss change is primarily due to a $154.6 million unfavorable impact from the change in fair value of the MRB asset (liability), excluding impacts of nonperformance risk, primarily driven by changes in market movements. This change was partially offset by a $105.4 million favorable impact from periodic and final settlements for derivatives used to hedge MRBs. See Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 10, Market Risk Benefits” for further information on market effects.

Operating expenses increased primarily due to $65.4 million of impairments of our distribution agreement intangible asset and contract cost asset in Hong Kong, a $34.2 million increase in compensation costs and an $18.3 million increase in nondeferrable commission expense. These increases were partially offset by a $65.6 million decrease in amounts credited to employee accounts in a nonqualified defined contribution pension plan.

Income Taxes

The effective income tax rate of (118)% for the three months ended March 31, 2025, changed from 15% for the three months ended March 31, 2024, primarily due to a decrease in pre-tax income with no proportionate change in permanent tax differences. See Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 13, Income Taxes” for a reconciliation of the corporate income tax rate to the effective income tax rate.

Results of Operations by Segment

Retirement and Income Solutions Segment

Retirement and Income Solutions Segment Summary Financial Data

Net revenue and average monthly account values are key metrics used to understand Retirement and Income Solutions earnings growth. Net revenue, which is used only at the segment level, is defined as operating revenues less benefits, claims and settlement expenses; liability for future policy benefits remeasurement (gain) loss; market risk benefit remeasurement (gain) loss and dividends to policyholders. Net revenue is impacted by: (1) changes in the equity markets and interest rates and (2) the difference between investment income earned on the underlying general account assets and the interest rate credited to the contracts. Average monthly account values include the net balances that customers have accumulated within their account, along with future policy benefits for retirement payout products. Average monthly account values are primarily impacted by net customer cash flows and credit market performance.

Principal Asset Management Segment

AUM

AUM forms the basis for generating our management fee revenues. However, in Chile, the Cuprum business operates differently, as most fees are collected with each deposit made by mandatory retirement customers, based on a capped salary level rather than asset levels. AUM growth is primarily driven by two factors: market performance and net cash flow. Market performance encompasses the returns from equity, fixed income, real estate and other alternative investments, while net cash flow reflects client deposits and withdrawals. Revenue growth increasingly depends on the fee levels associated with these deposits and withdrawals, which can vary significantly depending on the business or product mix. Additionally, our non-U.S. results are influenced by fluctuations in foreign currency exchange rates relative to the U.S. dollar. The AUM of our foreign subsidiaries is converted to U.S. dollars at the end of the reporting period using spot exchange rates, while revenue and expenses are translated using average exchange rates for the reporting period.

Three Months Ended March 31, 2025 Compared to Three Months Ended March 31, 2024

Pre-Tax Operating Earnings

Pre-tax operating earnings increased in our International Pension operations primarily due to $4.8 million of lower expenses in Asia. Pre-tax operating earnings decreased in our Investment Management operations due to a $19.7 million increase in variable compensation expense and a $2.4 million decrease in borrower fees revenue related to lower production in 2025. These decreases were partially offset by $18.5 million higher management fee revenue as a result of increased average AUM.

Benefits and Protection Segment

Benefits and Protection Segment Summary Financial Data

Premium and fees are a key metric for growth in the Benefits and Protection segment. We receive premiums on our specialty benefits insurance products as well as our traditional life insurance products. Fees are generated from our universal life, variable universal life and indexed universal life insurance products. We use several reinsurance programs to help manage the mortality and morbidity risk. Premium and fees are reported net of reinsurance premiums.

Three Months Ended March 31, 2025 Compared to Three Months Ended March 31, 2024

Pre-Tax Operating Earnings

Pre-tax operating earnings in our Specialty Benefits business increased $4.2 million primarily due to growth in the business. Pre-tax operating earnings in our Life Insurance business increased $12.9 million due to a change in the policyholder dividend obligation and $6.6 million due to higher yields on invested assets. These increases were offset by a $13.9 million impact from unfavorable claims experience.

Operating Revenues

Premium and fees increased primarily due to growth in our Specialty Benefits business.

Net investment income in our Specialty Benefits business increased $2.9 million due to higher yields on invested assets and $2.5 million due to growth in invested assets. Net investment income in our Life Insurance business decreased $16.1 million from mark-to-market changes on options associated with our indexed universal life insurance, partially offset by a $6.6 million increase due to higher yields on invested assets.

Total Expenses

Benefits, claims and settlement expenses in our Specialty Benefits business increased $18.3 million from growth in the business. Benefits, claims and settlement expenses in our Life Insurance business decreased $16.8 million from changes in reserves and interest credited associated with our indexed universal life business, partially offset by a $13.9 million increase from unfavorable claims experience.

Dividends to policyholders in our Life Insurance business decreased $12.9 million due to a change in the policyholder dividend obligation, partially offset by a $2.6 million increase due to higher dividends on our Closed Block business.

Operating expenses increased primarily due to higher net commissions in our Specialty Benefits business.

Liquidity and Capital Resources

Liquidity and capital resources represent the overall strength of a company and its ability to generate strong cash flows, borrow funds at a competitive rate and raise new capital to meet operating and growth needs. We are monitoring our liquidity closely and feel confident in our ability to meet all long-term obligations to customers, policyholders and debt holders. Our sources of strength include our laddered long-term debt maturities with the next maturity occurring in May 2025, access to revolving credit facility and contingent funding arrangements, a strong risk-based capital position and our available cash and liquid assets. Our legal entity structure has an impact on our ability to meet cash flow needs as an organization. Following is a simplified organizational structure.

​

Liquidity

Our liquidity requirements have been and will continue to be met by funds from consolidated operations as well as the issuance of commercial paper, common stock, debt or other capital securities and borrowings from credit facilities. We believe the cash flows from these sources are sufficient to satisfy the current liquidity requirements of our operations, including reasonably foreseeable contingencies.

We maintain a level of cash and securities which, combined with expected cash inflows from investments and operations, we believe to be adequate to meet anticipated short-term and long-term payment obligations. We will continue our prudent capital management practice of regularly exploring options available to us to maximize capital flexibility, including accessing the capital markets and careful attention to and management of expenses.

We perform rigorous liquidity stress testing to ensure our asset portfolio includes sufficient high quality liquid assets that could be utilized to bolster our liquidity position under increasingly stressed market conditions. These assets could be utilized as collateral for secured borrowing transactions with various third parties or by selling the securities in the open market if needed.

We also manage liquidity risk by limiting the sales of liabilities with features such as puts or other options that can be exercised at inopportune times. For example, as of March 31, 2025, approximately $14.6 billion, or 99%, of our institutional guaranteed investment contracts and funding agreements cannot be redeemed by contractholders prior to maturity. Our individual annuity liabilities also contain surrender charges and other provisions limiting early surrenders.

​

Universal life insurance and certain traditional life insurance policies are also subject to discretionary withdrawals by policyholders. However, life insurance policies tend to be less susceptible to withdrawal than our investment contracts because policyholders may be subject to a new underwriting process in order to obtain a new life insurance policy. In addition, our life insurance liabilities include surrender charges to discourage early surrenders.

We had the following short-term credit financing structures available with various financial institutions as of March 31, 2025:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | ​ |  | ​ |  | ​ | ​ |  | Amount

Total |  |  |  |  | ​ | $ | 907.3 | ​ | $ | 28.9

(1) | The credit facility is supported by sixteen banks.

(2) | The unsecured lines of credit can be used for repurchase agreements or other borrowings. Each line has a maturity of less than one year.

(3) | The amount outstanding is reported in short-term debt on the consolidated statements of financial position.

The revolving credit facility is committed and available for general corporate purposes. The credit facility also provides 100% back-stop support for our commercial paper program, of which we had no outstanding balances as of March 31, 2025 and December 31, 2024. Most of the banks supporting the credit facility have other relationships with us. Due to the financial strength and the strong relationships we have with these providers, we are comfortable we have very low risk the financial institutions would be unable or unwilling to fund this facility.

The Holding Companies: PFG and PFS. The principal sources of funds available to our parent holding company, PFG, are dividends from subsidiaries as well as its ability to borrow funds at competitive rates and raise capital to meet operating and growth needs. These funds are used by PFG to meet its obligations, which include the payment of dividends on common stock, debt service and the repurchase of stock. The declaration and payment of common stock dividends is subject to the discretion of our Board and will depend on our overall financial condition, results of operations, capital levels, cash requirements, future prospects, receipt of dividends or other distributions from Principal Life (as described below), risk management considerations and other factors deemed relevant by the Board. No significant restrictions limit the payment of dividends by PFG, except those generally applicable to corporations incorporated in Delaware.

121

Table of Contents

Dividends or other distributions from Principal Life, our primary subsidiary, are limited by Iowa law. Under Iowa law, Principal Life may pay dividends or make other distributions only from the earned surplus arising from its business and must receive the prior approval of the Commissioner of Insurance of the State of Iowa (the “Commissioner”) to pay stockholder dividends or make any other distribution if such distribution would exceed certain statutory limitations. Iowa law gives the Commissioner discretion to disapprove requests for distributions in excess of these limitations. Extraordinary dividends include those made, together with dividends and other distributions, within the preceding twelve months that exceed the greater of (i) 10% of statutory policyholder surplus as of the previous year-end excluding admitted disallowed interest maintenance reserve or (ii) the statutory net gain from operations from the previous calendar year, not to exceed earned surplus. Based on statutory results for the year ended December 31, 2024, the ordinary stockholder dividend limitation for Principal Life is approximately $1,313.1 million in 2025. However, because the dividend test is based on dividends previously paid over rolling twelve month periods, if paid before a specified date during 2025, some or all of such dividends may be extraordinary and require regulatory approval.

Total stockholder dividends paid by Principal Life to its parent for the three months ended March 31, 2025, were $350.0 million, all of which was extraordinary and approved by the Commissioner. As of March 31, 2025, we had $1,599.4 million of cash and liquid assets held in our holding companies and other subsidiaries, which is available for corporate purposes. Corporate balances held in foreign holding companies meet the indefinite reinvestment exception.

Operations. Our primary consolidated cash flow sources are premiums from insurance products, pension and annuity deposits, asset management fee revenues, administrative services fee revenues, income from investments and proceeds from the sales or maturity of investments. Cash outflows consist primarily of payment of benefits to policyholders and beneficiaries, income and other taxes, current operating expenses, payment of dividends to policyholders, payments in connection with investments acquired, payments made to acquire subsidiaries, payments relating to policy and contract surrenders, withdrawals, policy loans, interest payments and repayment of short-term debt and long-term debt. Our investment strategies are generally intended to provide adequate funds to pay benefits without forced sales of investments. For a discussion of our investment objectives and strategies, see “Investments.”

Cash Flows. Cash flow activity, as reported in our consolidated statements of cash flows, provides relevant information regarding our sources and uses of cash. The following discussion of our operating, investing and financing portions of the cash flows excludes cash flows attributable to the separate accounts.

Net cash provided by operating activities was $977.3 million and $584.2 million for the three months ended March 31, 2025 and 2024, respectively. Our insurance business typically generates positive cash flows from operating activities, as premiums collected from our insurance products and investment income received exceed acquisition costs, benefits paid, redemptions and operating expenses. These positive cash flows are then invested to support the obligations of our insurance and investment products and required capital supporting these products. Our cash flows from operating activities are affected by the timing of premiums, fees and investment income received and benefits and expenses paid. The increase in cash provided by operating activities in 2025 compared to 2024 was primarily due to fluctuations in receivables and payables associated with the timing of settlements.

Net cash used in investing activities was $952.7 million and $1,343.2 million for the three months ended March 31, 2025 and 2024, respectively. The decrease in cash used in investing activities was primarily due to higher net sales of mortgage loans in 2025 as compared to 2024.

Net cash used in financing activities was $360.8 million for the three months ended March 31, 2025, compared to net cash provided by financing activities of $219.7 million for the three months ended March 31, 2024. The increase in cash used in financing activities was due to lower net investment contract deposits in 2025 as compared to 2024 and a net decrease in banking operation deposits in 2025 as compared to an increase in 2024.

Guarantors and Issuers of Guaranteed Securities. PFG has issued certain notes pursuant to transactions registered under the Securities Act of 1933. Such notes include all currently outstanding senior notes (the “registered notes”). For additional information on the senior notes, see Item 8. “Financial Statements and Supplementary Data, Notes to Consolidated Financial Statements, Note 13, Debt” in our Annual Report on Form 10-K for the year ended December 31, 2024.

122

Table of Contents

PFS, a wholly owned subsidiary of PFG, has guaranteed each of the registered notes on a full and unconditional basis. The full and unconditional guarantees require PFS to satisfy the obligations of the guaranteed security immediately, if and when PFG has failed to make a scheduled payment thereunder. If PFS does not make such payment, any holder of the guaranteed security may immediately bring suit directly against PFS for payment of amounts due and payable. No other subsidiary of PFG has guaranteed any of the registered notes.

Summary financial information is presented below on a combined basis for PFG and PFS (the “obligor group”) and transactions between the obligor group have been eliminated. The summary financial information excludes subsidiaries that are not issuers or guarantors. Any investments by the obligor group in other subsidiaries have been excluded.

For long-term debt information, see Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 12, Long-Term Debt.”

Contingent Funding Agreements for Senior Debt Issuance. On March 6, 2025, we entered into a contingent funding agreement that gives us the right at any time over a thirty-year period to issue up to $500.0 million of senior notes.

123

Table of Contents

In March 2018, we entered into two contingent funding agreements that give us the right at any time over a ten-year or thirty-year period to issue up to $400.0 million or $350.0 million, respectively, of senior notes. In March 2025, we exercised our right to issue $400.0 million of senior notes under one of the agreements.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels. The fair value hierarchy gives the highest priority (Level 1) to unadjusted quoted prices in active markets for identical assets or liabilities and gives the lowest priority (Level 3) to unobservable inputs. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety considering factors specific to the asset or liability. See Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 17, Fair Value Measurements” for further details, including a reconciliation of changes in Level 3 fair value measurements.

As of March 31, 2025, 46% of our net assets (liabilities) were Level 1, 51% were Level 2 and 3% were Level 3. Excluding separate account assets as of March 31, 2025, 4% of our net assets (liabilities) were Level 1, 87% were Level 2 and 9% were Level 3.

As of December 31, 2024, 47% of our net assets (liabilities) were Level 1, 50% were Level 2 and 3% were Level 3. Excluding separate account assets as of December 31, 2024, 4% of our net assets (liabilities) were Level 1, 87% were Level 2 and 9% were Level 3.

Changes in Level 3 Fair Value Measurements

Net assets (liabilities) measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of March 31, 2025, were $7,736.7 million as compared to $8,046.3 million as of December 31, 2024. The decrease was primarily related to a decrease in the funds withheld payable embedded derivative net asset.

Investments

We had total consolidated assets as of March 31, 2025, of $313,003.3 million, of which $105,294.6 million were invested assets. A portion of our invested assets represent funds withheld backing reserves as part of coinsurance with funds withheld reinsurance agreements. The funds withheld assets and associated net investment income and net realized capital gains (losses) are not included in the discussions below as the investment risk is passed to the reinsurer. See Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 11, Reinsurance” for more information on the funds withheld assets. The rest of our total consolidated assets are comprised primarily of separate account assets for which we do not bear investment risk; therefore, the discussion and financial information below does not include such assets.

Overall Composition of Invested Assets

Invested assets as of March 31, 2025, were predominantly high quality and broadly diversified across asset class, individual credit, industry and geographic location. Asset allocation is determined based on cash flow and the risk/return requirements of our products. As shown in the following table, the major categories of invested assets are fixed maturities and mortgage loans.

Net Investment Income

The following table presents the yield and investment income, excluding net realized capital gains and losses, for our invested assets for the periods indicated. We calculate annualized yields using a simple average of asset classes at the beginning and end of the reporting period. The yields for available-for-sale fixed maturities are calculated using amortized cost. All other yields are calculated using carrying amounts.

Three Months Ended March 31, 2025 Compared to Three Months Ended March 31, 2024

Net investment income increased primarily due to higher average invested assets and yields in fixed maturities for our U.S. operations. These increases were partially offset by lower income in other investments, particularly related to hedge funds for our U.S. operations.

Net Realized Capital Gains (Losses)

The following table presents the contributors to net realized capital gains and losses for the periods indicated. The amounts below do not include net realized capital gains (losses) on funds withheld assets that are not passed to the reinsurer, which are separately reported on the consolidated statements of operations.

Table of Contents

Three Months Ended March 31, 2025 Compared to Three Months Ended March 31, 2024

Net realized capital losses increased primarily due to a held-for-sale write-down of an intangible asset in 2025, increased non-credit losses on available-for-sale fixed maturities and increased losses on non-hedged interest rate derivatives due to changes in interest rates. These increases were partially offset by gains versus losses on currency derivatives, increased gains on GMWB/RILA activities and gains versus losses on commercial mortgage loan reserve changes.

U.S. Investment Operations

In the following sections, we provide details about U.S. Investment Operations, excluding investments held as part of coinsurance with funds withheld agreements. We believe the details of the composition of our investment portfolio excluding the funds withheld are most relevant to an understanding of our operations that are pertinent to investors because all funds withheld assets support obligations and liabilities relating to reinsurance agreements. Guidelines are in place to ensure the investment risk associated with these fund withheld assets are appropriately managed. See Note 11, Reinsurance, for further information on the funds withheld assets.

Of our invested assets, $81,720.7 million were held by our U.S. operations as of March 31, 2025. Our U.S. invested assets are managed primarily by Principal Asset Management–Investment Management. Our Investment Committee, appointed by our Board, is responsible for establishing investment policies and monitoring risk limits and tolerances. Our primary investment objective is to maximize after-tax returns consistent with acceptable risk parameters. We seek to protect customers’ benefits by optimizing the risk/return relationship on an ongoing basis, through asset/liability matching, reducing credit risk, avoiding high levels of investments that may be redeemed by the issuer, maintaining sufficiently liquid investments and avoiding undue asset concentrations through diversification. We are exposed to two primary sources of investment risk:

| ● | credit risk, relating to the uncertainty associated with the continued ability of an obligor to make timely payments of principal and interest and

| ● | interest rate risk, relating to the market price and/or cash flow variability associated with changes in market yield curves.

Our ability to manage credit risk is essential to our business and our profitability. We devote considerable resources to the credit analysis of each new investment. We manage credit risk through industry, issuer and asset class diversification.

A dedicated committee, comprised of senior investment professional staff members, approves the credit rating for the fixed maturities we purchase. We have teams of security analysts, organized by industry and asset class, that analyze and monitor these investments. Investments held in the portfolio are monitored on a continuous basis with a formal review annually or more frequently if material events affect the issuer. The analysis includes both fundamental and technical factors. The fundamental analysis encompasses both quantitative and qualitative analysis of the issuer. The qualitative analysis includes an assessment of both accounting and management aggressiveness of the issuer. In addition, technical indicators such as stock price volatility and credit default swap levels are monitored. We regularly review our investments to determine whether we should re-rate them, employing the following criteria:

| ● | material changes in the issuer’s revenues, margins, capital structure or collateral values;

| ● | significant management or organizational changes;

| ● | significant changes regarding the issuer’s industry;

| ● | debt service coverage or cash flow ratios that fall below industry-specific thresholds;

| ● | violation of financial covenants and

| ● | other business factors that relate to the issuer.

We purchase credit default swaps to hedge certain credit exposures in our investment portfolio. We economically hedged credit exposure in our portfolio by purchasing credit default swaps with a notional amount of $155.0 million as of both March 31, 2025 and December 31, 2024. We sell credit default swaps and total return swaps to offer credit protection to investors when entering into synthetic replicating transactions. When selling credit protection, if there is an event of default by the referenced name, we are obligated to pay the counterparty the referenced amount of the contract and receive in return the referenced security. When selling total return swaps, if there is an event of default by the referenced name, we are obligated to compensate the protection buyer for any decline in the price of the referenced security. For further information on credit derivatives sold, see Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 5, Derivative Financial Instruments” under the caption, “Credit Derivatives Sold.”

Our use of derivatives exposes us to counterparty risk, or the risk that the counterparty fails to perform the terms of the derivative contract. We actively manage this risk by:

| ● | obtaining approval of all new counterparties by the Investment Committee;

| ● | establishing exposure limits that take into account non-derivative exposure we have with the counterparty as well as derivative exposure;

| ● | performing similar credit analysis prior to approval on each derivatives counterparty that we do when lending money on a long-term basis;

| ● | diversifying our risk across numerous approved counterparties;

| ● | implementing credit support annex (collateral) agreements (“CSAs”) for over-the-counter derivative transactions or similar agreements with a majority of our counterparties to further limit counterparty exposures, which provide for netting of exposures;

| ● | limiting exposure to A credit or better for over-the-counter derivative counterparties without CSAs;

| ● | conducting stress-test analysis to determine the maximum exposure created during the life of a prospective transaction;

| ● | daily monitoring of counterparty credit ratings, exposures and associated collateral levels and

| ● | trading mandatorily cleared contracts through centralized clearinghouses.

We manage our exposure on a net basis, whereby we net positive and negative exposures for each counterparty with agreements in place. For further information on derivative exposure, see Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 4, Investments” under the caption, “Balance Sheet Offsetting.”

A dedicated risk management team is responsible for centralized monitoring of the commercial mortgage loan portfolio. We apply a variety of guidelines to minimize credit risk in our commercial mortgage loan portfolio. When considering new commercial mortgage loans, we review the cash flow fundamentals of the property, make a physical assessment of the underlying commercial real estate, conduct a comprehensive market analysis and compare against industry lending practices. We use a proprietary risk rating model to evaluate all new and substantially all existing loans within the portfolio. The proprietary risk model is designed to stress projected cash flows under simulated economic and market downturns. Our lending guidelines are typically 75% or less loan-to-value ratio and a debt service coverage ratio of at least 1.2 times. We analyze investments outside of these guidelines based on cash flow quality, tenancy and other factors. The following table presents loan-to-value and debt service coverage ratios for our brick and mortar commercial mortgage loans:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Weighted average loan-to-value ratio | ​ | Debt service coverage ratio |
​ |  | March 31, 2025 |  | December 31, 2024 |  | March 31, 2025 |  | December 31, 2024 |
New mortgages |  | 47 | % | 53 | % | 1.4 | x | 1.7 | x
Entire mortgage portfolio |  | 50 | % | 50 | % | 2.3 | x | 2.3 | x

​

We also seek to manage call or prepayment risk arising from changes in interest rates. We assess and price for call or prepayment risks in all of our investments and monitor these risks in accordance with asset/liability management policies.

The amortized cost and weighted average yield, calculated using amortized cost, of non-structured fixed maturity securities that will be callable at the option of the issuer, excluding securities with a make-whole provision, were $2,344.8 million and 4.3%, respectively, as of March 31, 2025, and $2,091.5 million and 4.0%, respectively, as of December 31, 2024. In addition, the amortized cost and weighted average yield of RMBS, residential collateralized mortgage obligations, and asset-backed securities - home equity with material prepayment risk were $8,637.1 million and 4.2%, respectively, as of March 31, 2025, and $8,401.9 million and 4.1%, respectively, as of December 31, 2024.

Our investment decisions and objectives are a function of the underlying risks and product profiles of each primary business operation. In addition, we diversify our product portfolio offerings to include products that contain features that will protect us against fluctuations in interest rates. Those features include adjustable crediting rates, policy surrender charges and market value adjustments on liquidations. For further information on our management of interest rate risk, see Item 3. “Quantitative and Qualitative Disclosures About Market Risk – Interest Rate Risk.”

​

We believe it is desirable to hold residential mortgage-backed pass-through securities due to their credit quality and liquidity as well as portfolio diversification characteristics. Our portfolio is comprised of Government National Mortgage Association, Federal National Mortgage Association and Federal Home Loan Mortgage Corporation pass-through securities. In addition, our residential collateralized mortgage obligation portfolio offers structural features that allow cash flows to be matched to our liabilities.

We purchase CMBS to diversify the overall credit risks of the fixed maturities portfolio and to provide attractive returns. The primary risks in holding CMBS are structural and credit risks. Structural risks include the security’s priority in the issuer’s capital structure, the adequacy of and ability to realize proceeds from the collateral and the potential for prepayments. Credit risks involve collateral and issuer/servicer risk where collateral and servicer performance may deteriorate. CMBS are predominantly comprised of large pool securitizations that are diverse by property type, borrower and geographic dispersion. The risks to any CMBS deal are determined by the credit quality of the underlying loans and how those loans perform over time. Another key risk is the vintage of the underlying loans and the state of the markets during a particular vintage.

130

Table of Contents

Similar to CMBS, we purchase ABS for diversification and to provide attractive returns. The primary risks in holding ABS are also structural and credit risks, which are similar to those noted above for CMBS. Our ABS portfolio is diversified by type of asset, issuer, and vintage. We actively monitor holdings of ABS to recognize adverse changes in the risk profile of each security. Prepayments in the ABS portfolio are, in general, insensitive to changes in interest rates or are insulated from such changes by call protection features. In the event we are subject to prepayment risk, we monitor the factors that impact the level of prepayment and prepayment speed for those ABS. In addition, we hold a diverse class of securities, which limits our exposure to any one security.

The international exposure held in our U.S. operation’s fixed maturities portfolio was 14% of total fixed maturities as of both March 31, 2025 and December 31, 2024. It is comprised of corporate and foreign government fixed maturities.

International fixed maturities exposure is determined by the country of risk of the obligor entity. All international fixed maturities held by our U.S. operations are either denominated in U.S. dollars or have been swapped into U.S. dollar equivalents. Our international investments are analyzed internally by country and industry credit investment professionals. We control concentrations using issuer and country level exposure benchmarks, which are based on the credit quality of the issuer and the country. Our investment policy limits total international fixed maturities investments and we are within those internal limits. Exposure to Canada is not included in our international exposure. As of March 31, 2025 and December 31, 2024, our investments in Canada totaled $969.5 million and $966.1 million, respectively.

Fixed Maturities Credit Concentrations. One aspect of managing credit risk is through industry, issuer and asset class diversification. Our credit concentrations are managed to established limits. The top 10 exposures comprised 5.4% of single-name credit fixed maturity exposures as of both March 31, 2025 and December 31, 2024.

Fixed Maturities Valuation and Credit Quality. Valuation techniques for the fixed maturities portfolio vary by security type and the availability of market data. The use of different pricing techniques and their assumptions could produce different financial results. See Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 17, Fair Value Measurements” for further details regarding our pricing methodology. Once prices are determined, they are reviewed by pricing analysts for reasonableness based on asset class and observable market data. Investment analysts who are familiar with specific securities review prices for reasonableness through direct interaction with external sources, review of recent trade activity or use of internal models. All fixed maturities placed on the “watch list” are periodically analyzed by investment analysts. These analysts periodically meet with the Chief Investment Officer and the Portfolio Managers to determine reasonableness of the analysts’ prices. The valuation of bonds for which a credit loss exists and there is no quoted price is typically based on relative value analysis and the present value of the future cash flows expected to be received. Although we believe these values reasonably reflect the fair value of those securities, the key assumptions about risk premiums, performance of underlying collateral (if any) and other market factors involve qualitative and unobservable inputs.

The Securities Valuation Office (“SVO”) of the National Association of Insurance Commissioners (“NAIC”) monitors the bond investments of insurers for regulatory capital and reporting purposes and, when required, assigns securities to one of six categories referred to as NAIC designations. Although NAIC designations are not produced to aid the investment decision making process, NAIC designations may serve as a reasonable proxy for Nationally Recognized Statistical Rating Organizations’ (“NRSRO”) credit ratings for certain bonds. For most corporate bonds, NAIC designations 1 and 2 include bonds generally considered investment grade by such rating organizations. Bonds are considered investment grade when rated ‘‘Baa3’’ or higher by Moody’s, or ‘‘BBB-’’ or higher by S&P. NAIC designations 3 through 6 include bonds generally referred to as below investment grade. Bonds are considered below investment grade when rated ‘‘Ba1’’ or lower by Moody’s, or ‘‘BB+’’ or lower by S&P.

131

Table of Contents

For loan-backed and structured securities, as defined by the NAIC, the NAIC designation is not always a reasonable indication of an NRSRO rating as described below. For CMBS and non-agency RMBS, Blackrock Solutions undertakes the modeling of those NAIC designations. This may result in a final designation being higher or lower than the NRSRO credit rating.

The following table presents our total fixed maturities by NAIC designation as of the periods indicated as well as the percentage, based on fair value, that each designation comprises.

Fixed maturities included 59 securities with an amortized cost of $785.8 million, gross gains of $7.9 million, gross losses of $6.5 million, valuation allowance of $0.0 million and a carrying amount of $787.2 million as of March 31, 2025, that were still pending a review and assignment of a designation by the SVO or NRSRO ratings to be assigned. Due to the timing of when fixed maturities are purchased, legal documents are filed and the review by the SVO is completed, or NRSRO ratings that have expired or been withdrawn, we will always have securities in our portfolio that are unrated over a reporting period. In these instances, an equivalent designation is assigned based on our fixed income analyst’s assessment.

Commercial Mortgage-Backed Securities. As of March 31, 2025, based on amortized cost, 96% of our CMBS portfolio had an NAIC designation of 1.

The following table presents our exposure by credit quality based on NAIC designations for our CMBS portfolio as of the periods indicated.

Fixed Maturities Watch List. We monitor any decline in the credit quality of fixed maturities through the designation of “problem securities,” “potential problem securities” and “restructured securities”. We define problem securities in our fixed maturity portfolio as securities: (i) with principal and/or interest payments in default or where default is perceived to be imminent in the near term, or (ii) issued by a company that went into bankruptcy subsequent to the acquisition of such securities. We define potential problem securities in our fixed maturity portfolio as securities included on an internal “watch list” for which management has concerns as to the ability of the issuer to comply with the present debt payment terms and which may result in the security becoming a problem or being restructured. The decision whether to classify a performing fixed maturity security as a potential problem involves significant subjective judgments by our management as to the likely future industry conditions and developments with respect to the issuer. We define restructured securities in our fixed maturity portfolio as securities where a concession has been granted to the borrower related to the borrower’s financial difficulties that would not have otherwise been considered. We determine that restructures should occur in those instances where greater economic value will be realized under the new terms than through liquidation or other disposition and may involve a change in contractual cash flows. If the present value of the restructured cash flows is less than the current cost of the asset being restructured, a realized capital loss is recorded in net income and a new cost basis is established.

The following table presents the total carrying amount of our fixed maturities portfolio, as well as its problem, potential problem and restructured fixed maturities for the periods indicated.

Fixed Maturities Credit Losses. Each reporting period, a group of individuals including the Chief Investment Officer, our Portfolio Managers, the assigned analysts and representatives from Investment Accounting review all securities to determine whether a credit loss exists. The analysis focuses on each issuer’s ability to service its debts in a timely fashion. Formal documentation of the analysis and our decision is prepared and approved by management. For additional details regarding our process to identify and evaluate securities with credit losses, see Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 4, Investments” under the caption, “Allowance for Credit Loss.”

We would not consider a security with unrealized losses to have a decline in value due to credit when it is not our intent to sell the security, it is not more likely than not that we would be required to sell the security before recovery of the amortized cost, which may be maturity, and we expect to recover the amortized cost basis. However, we do sell securities under certain circumstances, such as when we have evidence of a change in the issuer’s creditworthiness, when we anticipate poor relative future performance of securities, when a change in regulatory requirements modifies what constitutes a permissible investment or the maximum level of investments held or when there is an increase in capital requirements or a change in risk weights of debt securities. Sales generate both gains and losses.

A number of significant risks and uncertainties are inherent in the process of monitoring credit losses and determining the allowance for credit loss. These risks and uncertainties include: (1) the risk that our assessment of an issuer’s ability to meet all of its contractual obligations will change based on changes in the credit characteristics of that issuer, (2) the risk that the economic outlook will be worse than expected or have more of an impact on the issuer than anticipated, (3) the risk that our investment professionals are making decisions based on fraudulent or misstated information in the financial statements provided by issuers and (4) the risk that new information obtained by us or changes in other facts and circumstances lead us to change our intent to not sell the security prior to recovery of its amortized cost. Any of these situations could result in a charge to net income in a future period.

The net realized loss relating to the change in the allowance for credit loss and credit related sales of fixed maturities was $5.0 million and $8.1 million for the three months ended March 31, 2025 and 2024, respectively.

Of the $3,808.2 million in gross unrealized losses as of March 31, 2025, $4.9 million in losses were attributed to securities scheduled to mature in one year or less, $197.9 million attributed to securities scheduled to mature between one to five years, $466.1 million attributed to securities scheduled to mature between five to ten years, $2,252.1 million attributed to securities scheduled to mature after ten years and $887.2 million related to mortgage-backed and other ABS that are not classified by maturity year. As of March 31, 2025, we were in a $3,260.1 million net unrealized loss position as compared to a $3,769.9 million net unrealized loss position as of December 31, 2024. The $509.8 million decrease in net unrealized losses for the three months ended March 31, 2025, can be attributed to a decrease in interest rates, which was partially offset by a widening of credit spreads.

Fixed Maturities Available-For-Sale Unrealized Losses. We believe our long-term fixed maturities portfolio is well diversified among industry types and between publicly traded and privately placed securities. Each year, we direct the majority of our net cash inflows into investment grade fixed maturities. Our current policy is to limit the percentage of fixed maturities invested in below investment grade assets to 15%.

We invest in privately placed fixed maturities to enhance the overall value of the portfolio, increase diversification and obtain higher yields than are possible with comparable quality public market securities. Generally, private placements provide broader access to management information, strengthened negotiated protective covenants, call protection features and, where applicable, a higher level of collateral. They are, however, generally not freely tradable because of restrictions imposed by U.S. federal and state securities laws and illiquid trading markets.

The following table presents our fixed maturities available-for-sale by investment grade and below investment grade as of the periods indicated.

Mortgage Loans

Mortgage loans consist of commercial mortgage loans on real estate and residential mortgage loans. For further details about residential mortgage loans, see Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 4, Investments” under the caption, “Financing Receivables.”

Commercial Mortgage Loans. We generally report commercial mortgage loans on real estate at cost adjusted for amortization of premiums and accrual of discounts, computed using the interest method and net of valuation allowances.

Commercial mortgage loans play an important role in our investment strategy by:

| ● | providing strong risk-adjusted relative value in comparison to other investment alternatives;

| ● | enhancing total returns and

| ● | providing strategic portfolio diversification.

As a result, we have focused on constructing a high quality portfolio of mortgages. Our portfolio is generally comprised of mortgages originated with conservative loan-to-value ratios, high debt service coverages and general purpose property types with a strong credit tenancy.

Our commercial mortgage loan portfolio consists primarily of non-recourse, fixed rate mortgages on fully or near fully leased properties. The mortgage portfolio is comprised primarily of office properties, apartments, well-anchored retail properties and general-purpose industrial properties.

Our commercial mortgage loan portfolio is diversified by geography and specific collateral property type. Commercial mortgage lending in the state of California accounted for 23% and 24% of our commercial mortgage loan portfolio before valuation allowance as of March 31, 2025 and December 31, 2024, respectively. We are, therefore, exposed to potential losses resulting from the risk of catastrophes, including but not limited to earthquakes, fires, drought, extreme heat, flooding, and tsunamis, that may affect the region. For the years ended March 31, 2025 and December 31, 2024, we did not experience any material losses due to the aforementioned catastrophe risks.

The typical borrower in our commercial mortgage loan portfolio is a single purpose entity or single asset entity. As of March 31, 2025 and December 31, 2024, the total number of commercial mortgage loans outstanding were 608 and 620, of which 36% and 35% were for loans with principal balances less than $10.0 million as of March 31, 2025 and December 31, 2024, respectively. The average loan size of our commercial mortgage portfolio was $23.1 million and $23.2 million as of March 31, 2025 and December 31, 2024, respectively.

Commercial Mortgage Loan Credit Monitoring. For further details on monitoring and management of our commercial mortgage loan portfolio, see Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 4, Investments” under the caption, “Financing Receivables Credit Monitoring.”

We categorize loans that are 60 days or more delinquent, loans in process of foreclosure and loans with borrowers or credit tenants in bankruptcy that are delinquent as “problem” loans. We categorize loans that are delinquent less than 60 days where the default is expected to be cured and loans with borrowers or credit tenants in bankruptcy that are current as “potential problem” loans. The decision whether to classify a loan delinquent less than 60 days as a potential problem involves significant subjective judgments by management as to the likely future economic conditions and developments with respect to the borrower. We categorize loans for which the original note rate has been reduced below market and loans for which the principal has been reduced as “restructured” loans. We also consider loans that are refinanced more than one year beyond the original maturity or call date at below market rates as restructured.

Table of Contents

We had two delinquent problem commercial mortgage loans with a carrying amount of $20.5 million for which we had a valuation allowance of $18.8 million as of March 31, 2025. We also had one potential problem commercial mortgage loan with a carrying amount of $65.5 million for which we had a valuation allowance of $28.0 million and one restructured problem commercial mortgage loan with a carrying amount of $34.1 million for which we had a valuation allowance of $34.1 million as of March 31, 2025. We had three delinquent problem commercial mortgage loans with a carrying amount of $20.6 million for which we had a valuation allowance of $18.9 million as of December 31, 2024. We also had two potential problem commercial mortgage loans with a carrying amount of $140.5 million for which we had a valuation allowance of $33.0 million and one restructured problem commercial mortgage loan with a carrying amount of $34.1 million for which we had a valuation allowance of $34.1 million as of December 31, 2024.

Commercial Mortgage Loan Valuation Allowance. We establish the commercial mortgage loan valuation allowance at levels considered adequate to absorb estimated expected credit losses within the portfolio. For further details on the commercial mortgage loan valuation allowance, see Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements, Note 4, Investments” under the caption, “Financing Receivables Valuation Allowance.”

Real Estate

Real estate consists primarily of commercial equity real estate. As of March 31, 2025 and December 31, 2024, the carrying amount of our equity real estate investment was $2,479.0 million and $2,463.7 million, respectively. Our commercial equity real estate is held in the form of wholly owned real estate, real estate acquired upon foreclosure of commercial mortgage loans and majority owned interests in real estate joint ventures.

Equity real estate is categorized as either “real estate held for investment” or “real estate held for sale.” The carrying value of real estate held for investment is generally adjusted for impairments whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. Such impairment adjustments are recorded as net realized capital losses in our consolidated results of operations. No such impairment adjustments were recorded for the three months ended March 31, 2025 or for the year ended December 31, 2024.

Once we identify a real estate property to be sold and it is probable that it will be sold, we classify the property as held for sale. We establish a valuation allowance subject to periodic revisions, if necessary, to adjust the carrying value of the property to reflect the lower of its current carrying value or the fair value, less associated selling costs. The valuation allowance did not change for the three months ended March 31, 2025 or for the year ended December 31, 2024.

We use research, both internal and external, to recommend appropriate product and geographic allocations and changes to the equity real estate portfolio. We monitor product, geographic and industry diversification separately and together to determine the most appropriate mix.

Equity real estate is distributed across geographic regions of the country. As of March 31, 2025, our largest equity real estate portfolio concentration was in the Pacific (48%) region of the United States. By property type, our largest concentrations were in Industrial (32%) and Office (32%) as of March 31, 2025.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market Risk Exposures and Risk Management

Market risk is the risk we will incur losses due to adverse fluctuations in market rates and prices. Our primary market risk exposures are to interest rates, equity markets and foreign currency exchange rates. The active management of market risk is an integral part of our operations. We manage our overall market risk exposure within established risk tolerance ranges using several approaches, including:

| ● | rebalancing our existing asset or liability portfolios;

| ● | controlling the risk structure of newly acquired assets and liabilities and

| ● | using derivative instruments to modify the market risk characteristics of existing assets or liabilities or assets expected to be purchased.

​

Interest Rate Risk

Interest rate risk is the risk of economic losses due to adverse changes in interest rates. Interest rate risk arises primarily from our holdings in interest sensitive assets and liabilities. Changes in interest rates impact numerous aspects of our operations, including but not limited to:

| ● | yield on our invested assets;

| ● | rate of interest we credit to contractholder account balances;

| ● | timing of cash flows on assets and liabilities containing embedded prepayment options;

| ● | cost of hedging our GMWB rider;

| ● | discount rate used in valuing our liability for future policy benefits for long-duration insurance and annuity contracts;

| ● | discount rate used in valuing our pension and OPEB obligations;

| ● | statutory reserve and capital requirements;

| ● | asset-based fees earned on the fixed income assets we manage;

| ● | interest expense on our long-term borrowings;

| ● | fair value of intangible assets in our reporting units and

| ● | fair value of financial assets and liabilities held at fair value on our consolidated statements of financial position.

Lower interest rates generally result in lower profitability in the long-term. Conversely, higher interest rates generally result in higher profitability in the long-term. However, an increase in market interest rates may cause a decline in the value of financial assets held at fair value on our consolidated statements of financial position.

Impact of Changes in Long-Term Interest Rate Assumptions

We use long-term interest rate assumptions to calculate MRBs, certain reserves and benefit plan obligations in accordance with U.S. GAAP. In setting these assumptions, we consider a variety of factors, including historical experience, emerging trends and future expectations. We evaluate our assumptions on at least an annual basis. Due to the long-term nature of our assumptions, we generally do not revise our assumptions in response to short-term fluctuations in market interest rates. However, we will consider revising our assumptions if a significant change occurs in the factors noted above.

A reduction in our long-term interest rate assumptions may result in increases in MRB liabilities and certain reserves.

Impact of Changes in Interest Rates

Changes in interest rates or a sustained low interest rate environment may result in the following impacts, which would impact our financial position and results of operations:

​

Impact of Falling Interest Rates or Sustained Low Interest Rates | Impact of Rising Interest Rates
Adverse Impacts: | Positive Impacts:
A reduction in investment income, which may be partially offset by a reduction in the interest we credit on contractholder account balances; however, our ability to lower crediting rates may be constrained by guaranteed minimum interest rates and competitive pressures | An increase in investment income, which may be partially or fully offset by an increase in the interest we credit on contractholder account balances
An increase in the cost of hedging our GMWB rider | A decrease in the cost of hedging our GMWB rider
An increase in MRB liabilities and certain reserves | A decrease in MRB liabilities and certain reserves
A reduction in the discount rate used to measure reserves for long-duration insurance and annuity contracts, leading to an increase in our reserves | An increase in the discount rate used to measure reserves for long-duration insurance and annuity contracts, leading to a decrease in our reserves
A reduction in the discount rate used in valuing our pension and OPEB obligations, leading to an increase in our Projected Benefit Obligation, Net Periodic Pension Cost, Accumulated Postretirement Benefit Obligation and Net Periodic Benefit Cost | An increase in the discount rate used in valuing our pension and OPEB obligations, leading to a decrease in our Projected Benefit Obligation, Net Periodic Pension Cost, Accumulated Postretirement Benefit Obligation and Net Periodic Benefit Cost
An increase in statutory capital we are required to hold as well as the amount of assets we must maintain to support statutory reserves | A decrease in statutory capital we are required to hold as well as the amount of assets we must maintain to support statutory reserves
An increase in prepayments or redemptions on mortgages and bonds we own, which would force us to reinvest the proceeds at lower interest rates | A decrease in prepayments or redemptions on mortgages and bonds we own, which would reduce our opportunity to reinvest the proceeds at higher interest rates
​ | ​
Positive Impacts: | Adverse Impacts:
An increase in the value of the fixed income assets we manage, resulting in an increase in our fee revenue in the short-term | A decrease in the value of the fixed income assets we manage, resulting in a decrease in our fee revenue in the short-term
A decrease in the interest expense on our long-term borrowings, to the extent the borrowings have adjustable rates or we are able to refinance our obligations at lower interest rates | An increase in the interest expense on our long-term borrowings, to the extent the borrowings have adjustable rates or we refinance our obligations at higher interest rates
An increase in the fair value of certain financial assets held at fair value on our consolidated statements of financial position | A decrease in the fair value of certain financial assets held at fair value on our consolidated statements of financial position, as discussed below
​ | A reduction in the fair value of intangible assets in our reporting units, potentially leading to an impairment of goodwill or other intangible assets

​

​

We estimate a hypothetical 100 basis point immediate, parallel decrease in U.S. interest rates would impact segment pre-tax operating earnings between (1)% and 1% over the next twelve months. This estimate reflects the impact of routine management actions in response to changes in interest rates, such as reducing the interest rates we credit on contractholder account balances, but does not reflect the impact of other actions management may consider, such as curtailing sales of certain products.

The selection of a 100 basis point immediate, parallel decrease in U.S. interest rates should not be construed as a prediction by us of future market events, but rather as an illustration of the impact of such an event. Our exposure will change as a result of ongoing portfolio transactions in response to new business, management’s assessment of changing market conditions and changes in our mix of business.

If market rates increase rapidly, policy surrenders, withdrawals and requests for policy loans may increase as customers seek to achieve higher returns. Excess lapses may result in an acceleration of amortization for our DAC and other actuarial balances. We may be required to sell assets to raise the cash necessary to respond to such surrenders, withdrawals and loans, thereby realizing capital losses on the assets sold.

Guaranteed Minimum Interest Rate Exposure. The following table provides detail on the differences between the interest rates being credited to contractholders as of March 31, 2025, and the respective GMIR. Amounts for contracts without significant fee revenues such as GICs, funding agreements, retail fixed income annuities and guaranteed pension contracts are excluded. Additionally, amounts for contracts that are reinsured are also excluded.

Impact of Rising Interest Rates on the Fair Value of Financial Assets. An increase in market interest rates may cause a decline in the value of financial assets held at fair value on our consolidated statements of financial position. Although changes in the fair value of our financial assets due to changes in interest rates may impact the amount of equity reported in our consolidated statements of financial position, these changes will not cause an economic gain or loss unless we sell investments, terminate derivative positions, record an allowance for credit loss, or determine a derivative instrument is no longer an effective hedge.

We estimate a hypothetical 100 basis point immediate, parallel increase in interest rates would reduce the net reported fair value of our financial assets and derivatives by $2,789.2 million as of March 31, 2025, compared to $2,670.8 million as of December 31, 2024. This estimate only reflects the change in fair value for financial assets and derivatives reported at fair value on our consolidated statements of financial position. Assets and liabilities not reported at fair value on our consolidated statements of financial position – including mortgage loans, liabilities relating to insurance contracts, investment contracts, debt and bank deposits – are excluded from this sensitivity analysis. We believe the excluded liability items would economically serve as a partial offset to the net interest rate risk of the financial instruments included in the sensitivity analysis. Separate account assets and liabilities are also excluded from this estimate, as any interest rate risk is borne by the holder of the separate account. Assets backing reserves as part of a coinsurance with funds withheld agreement are excluded from this estimate, as any interest rate risk is passed to the reinsurer. For more information on fair value measurements, see Item 8. “Financial Statements and Supplementary Data, Notes to Consolidated Financial Statements, Note 18, Fair Value Measurements” in our Annual Report on Form 10-K for the year ended December 31, 2024.

Our selection of a 100 basis point immediate, parallel increase in interest rates is a hypothetical rate scenario we use to demonstrate potential risk. While a 100 basis point immediate, parallel increase does not represent our view of future market changes, it is a near term reasonably possible hypothetical change that illustrates the potential impact of such events. While this sensitivity analysis provides a representation of interest rate sensitivity, it is based on our portfolio exposures at a point in time and may not be representative of future market results. These exposures will change as a result of ongoing portfolio transactions in response to new business, management’s assessment of changing market conditions and available investment opportunities.

Our net estimated potential loss in fair value as of March 31, 2025, increased $118.4 million from December 31, 2024, primarily driven by growth in the portfolio.

Interest Rate Risk Management

We manage interest rate risk through the use of an integrated risk management framework. This helps us identify, assess, monitor, report and manage our risks within established limits and risk tolerances. Our internal risk committees monitor and discuss our risk profile and identify necessary actions to mitigate impacts from interest rate risk.

The product designs within our business units result in a variety of different interest rate risk profiles. Therefore, our business units use a variety of different approaches for managing their asset and liability interest rate risks.

| ● | Retirement Business Stable Cash Flows – For stable and predictable cash flow liabilities, such as pension risk transfer, WSRS, and investment only, we use investment strategy and hedges to tightly align the cash flow run off of these asset and liability cash flows. Immunization analysis is also utilized in the management of interest rate risk.

| ● | U.S. Insurance Stable Cash Flows – Our insurance businesses in many instances contain long-term guarantees with stable and predictable liability cash flows and recurring premiums. We manage the interest rate risk through investment strategy, product crediting rates and analyzing duration and embedded value sensitivity.

| ● | Principal Asset Management – Our international businesses operate within local regulations and financial market conditions (e.g., derivative markets, assets available) to achieve similar asset and liability cash flow management objectives. In locations with a limited availability of long-dated assets and derivative markets, the duration gap is managed to risk tolerances specific to each location.

We also limit our exposure to interest rate risk through our business mix and strategy. We have intentionally limited our exposure to specific products where investment margins are critical to the product’s profitability, and we continue to emphasize the sale of products that generate revenues in the form of fees for service or premiums for insurance coverage and expose us to minimal interest rate risk.

Prepayment risk is controlled by limiting our exposure to investments that are prepayable without penalty prior to maturity at the option of the issuer. We also require additional yield on these investments to compensate for the risk the issuer will exercise such option. Prepayment risk is also controlled by limiting the sales of liabilities with features such as puts or other options that can be exercised at inopportune times. We manage the interest rate risk associated with our long-term borrowings by monitoring the interest rate environment and evaluating refinancing opportunities as maturity dates approach.

The plan fiduciaries use a Dynamic Asset Allocation strategy for our qualified defined benefit pension plan, which strategically allocates an increasing portion of the assets of the pension plan to fixed income securities as the funding status improves. The intended purpose of using the Dynamic Asset Allocation strategy is that the expected change in the value of the plan assets and the change in pension benefit obligation due to market movements are more likely to have more correlation versus a static allocation of assets between categories. For more information see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates — Benefit Plans” and Item 8. “Financial Statements and Supplementary Data, Notes to Consolidated Financial Statements, Note 15, Employee and Agent Benefits” in our Annual Report on Form 10-K for the year ended December 31, 2024.

Use of Derivatives to Manage Interest Rate Risk. We use or have used various derivative financial instruments to manage our exposure to fluctuations in interest rates, including interest rate swaps, interest rate options, TBA forwards, bond forwards, treasury forwards, swaptions and futures. We use interest rate swaps, treasury forwards and futures contracts to hedge against changes in the value of the GMWB MRB. We use interest rate swaps, treasury forwards and have used TBA forwards primarily to more closely match the interest rate characteristics of assets and liabilities. They can be used to change the sensitivity to the interest rate of specific assets and liabilities as well as an entire portfolio. We use interest rate swaps to manage our exposure to cash flow variability on recognized assets due to fluctuations in market interest rates. We use bond forwards to fix the purchase price of a bond at a specified date in the future. We use interest rate options to manage prepayment risks in our assets and minimum guaranteed interest rates and lapse risks in our liabilities. We have purchased swaptions to hedge interest rate exposure for certain assets and liabilities.

Foreign Currency Risk

Foreign currency risk is the risk we will incur economic losses due to adverse fluctuations in foreign currency exchange rates. This risk arises from foreign currency-denominated funding agreements issued to nonqualified institutional investors in the international market, foreign currency-denominated fixed maturity and equity securities, and our international operations, including expected cash flows and potential acquisition and divestiture activity.

We estimate as of March 31, 2025, a 10% immediate unfavorable change in each of the foreign currency exchange rates to which we are exposed would result in no material change to the net fair value of our foreign currency-denominated instruments identified above because we effectively hedge foreign currency-denominated instruments to minimize exchange rate impacts, which is consistent with our estimate as of December 31, 2024. However, fluctuations in foreign currency exchange rates do affect the translation of segment pre-tax operating earnings and equity of our international operations into our consolidated financial statements.

For our international operations, we estimate a 10% immediate unfavorable change in each of the foreign currency exchange rates to which we were exposed would have resulted in a $277.8 million, or 7%, reduction in the total equity excluding noncontrolling interests of our international operations as of March 31, 2025, as compared to an estimated $277.0 million, or 7%, reduction as of December 31, 2024. We estimate a 10% unfavorable change in the average foreign currency exchange rates to which we were exposed through our international operations would have resulted in a $10.3 million, or 6%, reduction in segment pre-tax operating earnings of our international operations for the three months ended March 31, 2025, as compared to an estimated $9.6 million, or 5%, reduction for the three months ended March 31, 2024.

The selection of a 10% immediate unfavorable change in all currency exchange rates should not be construed as a prediction by us of future market events, but rather as an illustration of the potential impact of such an event. These exposures will change as a result of a change in the size and mix of our foreign operations.

Use of Derivatives to Manage Foreign Currency Risk. The foreign currency risk on funding agreements and fixed maturities in our U.S. operations is mitigated by using currency swaps that swap the foreign currency interest and principal payments to our functional currency. We did not have currency swap agreements associated with foreign-denominated liabilities as of March 31, 2025 and December 31, 2024. The notional amount of our currency swap agreements associated with foreign-denominated fixed maturities was $2,829.7 million and $2,669.3 million as of March 31, 2025 and December 31, 2024, respectively.

With regard to our international operations, in order to enhance the diversification of our investment portfolios we may invest in bonds denominated in a currency that is different than the currency of our liabilities. We use foreign exchange derivatives to economically hedge the currency mismatch. Our international operations had currency swaps with a notional amount of $205.5 million and $214.5 million as of March 31, 2025 and December 31, 2024, respectively. Our international operations also utilized currency forwards with a notional amount of $680.9 million and $694.8 million as of March 31, 2025 and December 31, 2024, respectively.

We use currency forwards to hedge currency risk associated with expected cash flows in our foreign operations. We held currency forwards with a notional of $191.0 million and $179.7 million as of March 31, 2025 and December 31, 2024, respectively.

Additionally, we use currency forwards to hedge net equity investments in our foreign operations, including certain sponsored investment funds. We held currency forwards with a notional amount of $50.3 million and $50.8 million as of March 31, 2025 and December 31, 2024, respectively.

We also use currency forwards to hedge certain foreign-denominated investments in our domestic operations. We held currency forwards with a notional amount of $56.0 million and $55.9 million as of March 31, 2025 and December 31, 2024, respectively.

Equity Risk

Equity risk is the risk we will incur economic losses due to adverse fluctuations in equity markets. As of March 31, 2025 and December 31, 2024, the fair value of our equity securities was $2,428.9 million and $2,295.0 million, respectively. We estimate a 10% decline in the prices of the equity securities would result in a decline in fair value of our equity securities of $242.9 million as of March 31, 2025, as compared to a decline in fair value of our equity securities of $229.5 million as of December 31, 2024.

We are also exposed to the risk that asset-based fees decrease as a result of declines in assets under management due to changes in investment prices and the risk that asset management fees calculated by reference to performance could be lower.

We also have equity risk associated with (1) universal life contracts that credit interest to customers based on changes in an external equity index; (2) variable annuity contracts that have a GMWB rider that allows the customer to make withdrawals of a specified annual amount, either for a fixed number of years or for the lifetime of the customer, even if the account value is reduced to zero; (3) variable annuity contracts that have a GMDB that allows the death benefit to be paid, even if the account value has fallen below the GMDB amount; (4) SEC-registered annuity contracts with returns linked to an external equity index and (5) investment contracts in which the return is subject to minimum contractual guarantees. We are also subject to equity risk based upon the assets that support our employee benefit plans. For further discussion of equity risk associated with these plans, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates — Benefit Plans” in our Annual Report on Form 10-K for the year ended December 31, 2024.

We estimate an immediate 10% downward equity shock, followed by a 2% per quarter increase would reduce our annual segment pre-tax operating earnings by approximately 5% to 8% over the next twelve months. The selection of a 10% unfavorable equity shock should not be construed as a prediction by us of future market events, but rather as an illustration of the potential impact of such an event. Our exposure will change as a result of changes in our mix of business.

Separate and distinct from our equity risk associated with a decline in the equity indices, we also have equity risk associated with certain domestic alternative investments. These investments are comprised of several asset categories (including hedge funds, private equity, infrastructure and direct lending) that provide an attractive asset match to our long-dated liabilities and create diversification benefits to our fixed income investments. The risk profile of these investments is actively monitored by our Investment Committee and our corporate risk management function. Changes in the value of these investments will impact earnings. We estimate an immediate 10% decline in the value of those assets, followed by a 2% per quarter increase would reduce our annual segment pre-tax operating earnings by less than 8%. The selection of a 10% unfavorable change in the value of those assets should not be construed as a prediction of future market events, but rather as an illustration of the potential impact of such a decline in value of those assets.

Use of Derivatives to Manage Equity Risk. We economically hedge the universal life products, where the interest credited is linked to an external equity index, by purchasing options that match the product’s profile or selling options to offset existing exposures. We economically hedge certain investments using total return swaps to swap the equity risk for income enhancement. We economically hedge RILA index credit exposure using options and futures. We economically hedge the GMWB rider MRB exposure, which includes interest rate risk and equity risk, using futures, options, treasury forwards and interest rate swaps with notional amounts of $7,879.3 million and $7,678.0 million as of March 31, 2025, and December 31, 2024, respectively. The fair value of both MRBs and associated hedging instruments are sensitive to financial market conditions and the variance related to the change in fair value of these items for a given period is largely dependent on market conditions at the end of the period.
