2025 Form 10-K Market Risk

Market Risk

Market risk is the risk that we will incur losses due to adverse changes in interest rates, credit spreads, equity prices or foreign currency exchange rates. Adverse changes to these rates and prices may occur due to changes in fiscal policy, inflation, the economic climate, the liquidity of a market or market segment, insolvency or financial distress of key market makers or participants or changes in market perceptions of credit worthiness or risk tolerance. Our primary market risk exposures are to changes in interest rates, credit spreads and equity prices, and to a lesser extent, foreign currency exchange rates.

The active management of market risk is integral to our results of operations. We may use the following approaches to manage exposure to market risk within defined tolerance ranges:

1)Rebalance existing asset or liability portfolios

2)Change the type of investments purchased in the future

3)Use derivative instruments to modify the market risk characteristics of existing assets and liabilities or assets expected to be purchased

Overview In formulating and implementing guidelines for investing funds, we seek to earn attractive risk-adjusted returns that enhance our ability to offer competitive prices to customers while contributing to stable profits and long-term capital growth. Accordingly, our investment decisions and objectives are informed by underlying risks. Investment policies define the overall framework for managing market and other investment risks, including accountability and controls over risk management activities. Subsidiaries that conduct investment activities follow policies that have been approved by their respective boards of directors and which specify the investment limits and strategies that are appropriate given the liquidity, surplus, product profile and regulatory requirements of the subsidiary. Executive oversight of investment activities is conducted primarily through the subsidiaries’ boards of directors and legal entity investment committees. The Enterprise Risk and Return Council (“ERRC”) allocates a portion of enterprise risk and capital to the investment portfolio, determining enterprise risk tolerance, which is then cascaded to each subsidiary, as applicable, in conjunction with its board or investment committee.

We use widely accepted quantitative and qualitative approaches to measure, monitor and manage market risk. We evaluate our market risk exposure using multiple measures including but not limited to:

• Duration, a measure of the price sensitivity of assets and liabilities to changes in interest rates

• Value-at-risk, a statistical estimate that the change in fair value of a portfolio will exceed a certain amount over a given time horizon, at a specified probability

• Scenario analysis, an estimate of the potential changes in the fair value of a portfolio that could occur under hypothetical market conditions defined by changes to multiple market risk factors: interest rates, credit spreads, equity prices or currency exchange rates

• Sensitivity analysis, an estimate of the potential changes in the fair value of a portfolio that could occur using hypothetical shocks to a market risk factor The selection of measures used in our sensitivity analysis should not be construed as our prediction of future market events, but only as an illustration of the potential effect of such an event

In general, we establish investment portfolio asset allocation and market risk limits based upon a combination of these measures. The asset allocation limits place restrictions on the total funds that may be invested within an asset class. Comprehensive day-to-day management of market risk within defined tolerance ranges occurs as portfolio managers buy and sell within their respective markets based upon the acceptable boundaries established by investment policies. Although we apply a similar overall philosophy to market risk, the underlying business frameworks and the accounting and regulatory environments may differ between our products and therefore affect investment decisions and risk parameters. Our actual experience may differ from the results of the sensitivity measurements provided below.

Interest rate risk is the risk that we will incur a loss due to adverse changes in risk-free interest rates. This risk arises from many of our primary activities, as we invest substantial funds in interest-sensitive assets. Changes in interest rates can have favorable and unfavorable effects on our results. For example, increases in rates can improve investment income, but decrease the fair value of our fixed income securities portfolio which may result in sales of assets at losses. Decreases in rates could increase the fair value of our fixed income securities portfolio while decreasing future investment income due to reinvestment at lower market yields and accelerated pay-downs and prepayments of certain investments.

For our issued debt, we monitor market interest rates and evaluate refinancing opportunities as maturity dates approach. To mitigate this risk, we ladder the maturity dates of our debt. For our issued noncumulative perpetual preferred stock, we monitor market dividend rates and evaluate opportunities to redeem or refinance on or after specified dates. For further detail regarding our debt and our preferred stock, see Note 12 of the consolidated financial statements and the Capital Resources and Liquidity section of this Item.

2025 Form 10-KMarket Risk

Our assessment of interest rate risk reflects the effect of changing risk-free interest rates on interest-sensitive assets, including investments with callable or prepayable features. As of December 31, 2025, the fixed income portfolio duration, including the effects of interest rate derivatives, was 5.1 compared to 5.3 as of December 31, 2024.

(1)Includes the effects of interest rate derivatives.

(2)As of December 31, 2025, we held fixed income securities of $59.11 billion compared to $52.75 billion as of December 31, 2024.

Credit spread risk is the risk that we will incur a loss due to adverse changes in credit spreads (“spreads”). A credit spread is the additional yield on fixed income securities and loans above the risk-free rate that market participants require to compensate them for assuming credit, liquidity or prepayment risks. This risk arises from many of our primary activities, as we invest substantial funds in spread-sensitive fixed income assets.

Our assessment of credit spread risk reflects the effect of changing credit spreads on spread-sensitive assets, including investments with callable or prepayable features. As of December 31, 2025 and 2024, the spread duration(1) was 4.6 and 4.7, respectively.

(1)Includes the effects of credit derivatives.

Equity price risk is the risk that we will incur losses due to adverse changes in the levels of equity indices, the value of individual stocks, or private market valuations related to our limited partnership interests.

Equity investments(1) As of December 31, 2025, we held $7.27 billion in equity investments that comprise equity securities, excluding those with interest-bearing securities as their underlying investments, and including limited partnership interests where the underlying assets are predominately public equity securities, compared to $4.00 billion as of December 31, 2024.

(1)Includes the effects of equity derivatives.

Limited partnership interests As of December 31, 2025, we held $8.69 billion in limited partnership interests, excluding those limited partnership interests where the underlying assets are predominately public equity securities, compared to $8.95 billion as of December 31, 2024. These illiquid investments are primarily comprised of private equity and real estate funds, with valuation changes typically reflecting the idiosyncratic performance of the underlying asset.

For limited partnership interests, quarterly changes in fair values may not be highly correlated to equity indices in the short term.

Foreign currency exchange rate risk is the risk that we will incur economic losses due to adverse changes in foreign currency exchange rates. This risk primarily arises from our foreign equity investments, including common stocks, limited partnership interests, and our foreign operations. We use foreign currency derivative contracts to partially offset this risk.

As of December 31, 2025, we had $4.20 billion in foreign currency denominated investments, including the effects of foreign currency derivative contracts, and $1.53 billion net investment in our foreign subsidiaries, primarily related to our Canada operations. These amounts were $3.74 billion and $1.29 billion, respectively, as of December 31, 2024.

(1)Includes the effects of foreign currency derivative contracts and excludes the offset from liabilities in foreign currencies.

(2)Includes the effects of foreign currency derivative contracts and the offset from liabilities in foreign currencies.
