AFLAC INC

The Company uses derivative contracts to hedge foreign currency exchange rate risk and interest rate risk. The Company uses various strategies, including derivatives, to manage these risks. See Item 7A. Quantitative and Qualitative Disclosures About Market Risk in the 2024 Annual Report for more information about market risk and the Company’s use of derivatives.

Derivatives are designed to reduce risk on an economic basis while minimizing the impact on financial results. The Company’s derivatives programs vary depending on the type of risk being hedged. See Note 4 of the Notes to the Consolidated Financial Statements for:

•A description of the Company's derivatives, hedging strategies and underlying risk exposure.

•Information about the notional amount and fair market value of the Company's derivatives.

•Impact on earnings and other comprehensive income (loss) from various qualifying and non-qualifying hedging relationships.

Foreign Currency Exchange Rate Risk Hedge Program

The Company has deployed the following hedging strategies to mitigate exposure to foreign currency exchange rate risk:

•Aflac Japan hedges U.S. dollar-denominated investments back to yen (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).

•Aflac Japan maintains certain unhedged U.S. dollar-denominated securities, which serve as an economic currency hedge of a portion of the Company's investment in Aflac Japan, while utilizing foreign currency options to mitigate against significant movements in the yen/U.S. dollar exchange rate (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).

•The Parent Company designates yen-denominated liabilities (notes payable and loans) as non-derivative hedging instruments and designates certain foreign currency forwards and options as derivative hedges of the Company’s net investment in Aflac Japan(see Enterprise Corporate Hedging Program below).

•The Parent Company enters into forward and option contracts to accomplish a dual objective of hedging foreign currency exchange rate risk related to dividend payments by its subsidiary, ALIJ, and reducing enterprise-wide hedge costs(see Enterprise Corporate Hedging Program below).

The following table presents metrics related to Aflac Japan's U.S. dollar-denominated hedge program and the Parent Company's enterprise corporate hedging program, including associated amortized hedge costs/income, for the periods ended June 30. See the Results of Operations section of this MD&A for the Company's definition of amortized hedge costs/income.

(1) Notional is reported net of any offsetting positions within Aflac Japan or the Parent Company, respectively.

Amortized hedge costs/income can fluctuate based upon many factors, including the derivative notional amount, the length of time of the derivative contract, changes in both U.S. and Japan interest rates, and supply and demand for U.S. dollar funding. Amortized hedge costs/income have fluctuated in recent periods due to changes in the previously mentioned factors.

Aflac Japan’s U.S. Dollar-Denominated Hedge Program (U.S. Dollar Program)

Aflac Japan buys U.S. dollar-denominated investments, typically corporate bonds, and hedges them back to yen with foreign currency forwards and options to hedge foreign currency exchange rate risk. This economically creates yen assets that match yen liabilities during the life of the derivative and provides favorable capital treatment under the Japan solvency margin ratio (SMR) calculations. The currency risk being hedged is generally based on fair value of hedged investments. The following table summarizes the U.S. dollar-denominated investments held by Aflac Japan.

The U.S. Dollar Program includes all U.S. dollar-denominated investments in Aflac Japan other than the investments in certain consolidated VIEs where the instrument is economically converted to yen as a result of a derivative in the consolidated VIE. The Company uses foreign currency forwards to hedge foreign exchange risk on certain U.S. dollar-denominated investments in Aflac Japan's portfolio and one-sided foreign currency put options to mitigate the settlement risk on U.S. dollar-denominated assets related to extreme foreign currency rate changes. From time to time, Aflac Japan also maintains a collar program on a portion of its U.S. Dollar Program to mitigate against more extreme moves in foreign exchange and therefore support SMR. As of June 30, 2025, none of the Company's foreign currency options hedging Aflac Japan's U.S. dollar-denominated assets were in-the-money.

Foreign exchange derivatives used for hedging are periodically settled, which results in cash receipt or payment at inception, maturity or early termination. The following table presents the settlements associated with the Company's currency derivatives used for hedging Aflac Japan’s U.S. dollar-denominated investments.

Enterprise Corporate Hedging Program

The Company has designated certain yen-denominated liabilities and foreign currency forwards and options of the Parent Company as accounting hedges of its net investment in Aflac Japan. The Company's consolidated yen-denominated net asset position was partially hedged at $7.4 billion as of June 30, 2025, with hedging instruments comprised of $5.5 billion of yen-denominated debt and $1.9 billion of foreign currency forwards, compared with $5.9 billion as of December 31, 2024, with hedging instruments comprised of $4.1 billion of yen-denominated debt and $1.8 billion of foreign currency forwards.

The Company makes its accounting designation of net investment hedge at the beginning of each quarter. If the total of the designated Parent Company non-derivative and derivative notional is equal to or less than the Company's net investment in Aflac Japan, the hedge is deemed to be effective, and the currency exchange effect on the yen-denominated liabilities and the change in estimated fair value of the derivatives are reported in the unrealized foreign currency component of other comprehensive income. The Company's net investment hedge was effective during the three- and six-month periods ended June 30, 2025 and 2024, respectively. For additional information on the Company's net investment hedging strategy, see Note 4 of the Notes to the Consolidated Financial Statements.

In order to economically mitigate risks associated with the enterprise-wide exposure to the yen and the level and volatility of hedge costs, the Parent Company enters into foreign currency forward and option contracts. By buying U.S. dollars and selling yen, the Parent Company is effectively lowering its overall economic exposure to the yen. In addition to reducing yen exposure from dividend payments by Aflac Japan to the Parent Company, this strategy also reduces enterprise-wide hedge costs. This activity is reported in Corporate and other. The Company continually evaluates the program’s efficacy.

As part of the Company’s internal reinsurance platform, Aflac Re enters into foreign currency forwards with the Parent Company, and may enter into such forwards with third parties, to economically manage the currency mismatch between Aflac Re's assets, which are mostly denominated in U.S. dollars, and liabilities, which are mostly denominated in yen, in order to support and optimize Bermuda Monetary Authority (BMA) capital requirements. For additional information on the Company's internal reinsurance platform, see Note 8 of the Notes to the Consolidated Financial Statements and the Liquidity and Capital Resources section of this MD&A and Note 8 of the Notes to the Consolidated Financial Statements in the 2024 Annual Report.

Interest Rate Risk Hedge Program

Aflac Japan and Aflac U.S. use interest rate swaps from time to time to mitigate the risk of investment income volatility for certain variable-rate investments. Additionally, to manage interest rate risk associated with its U.S. dollar-denominated investments held by Aflac Japan, from time to time the Company utilizes interest rate swaptions.

For additional discussion of the risks associated with the foreign currency exposure refer to the Currency Risk section in Item 7A., Quantitative and Qualitative Disclosures about Market Risk, and Item 1A, specifically to the Risk Factors titled “The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" and “Lack of availability of acceptable yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity" in the 2024 Annual Report.

See Note 4 of the Notes to the Consolidated Financial Statements for additional information on the Company's hedging activities.
