	(6) Aflac Japan and the Parent Company utilize foreign currency forwards and options to hedge foreign currency exchange rate risk. The hedge cost/income on the table above reflects our FX forward protection of the hedged USD portfolio, and hedge costs on one sided options used as caps, and on tail-risk put options. The table does not include the notional amount and weighted average remaining tenor for these options. At December 31, 2022, Aflac Japan caps and put options notional amount was $13.5 billion with a weighted average remaining tenor of 6.4 months. At December 31, 2022, the Parent Company caps notional amount was $2.6 billion with a weighted average remaining tenor of 9.0 months.

Non-U.S. GAAP Financial Measures

This document includes references to the Company’s financial performance measures which are not calculated in accordance with United States generally accepted accounting principles (U.S. GAAP) (non-U.S. GAAP). The financial measures exclude items that the Company believes may obscure the underlying fundamentals and trends in insurance operations because they tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with insurance operations.

Due to the size of Aflac Japan, where the functional currency is the Japanese yen, fluctuations in the yen/dollar exchange rate can have a significant effect on reported results. In periods when the yen weakens, translating yen into dollars results in fewer dollars being reported. When the yen strengthens, translating yen into dollars results in more dollars being reported. Consequently, yen weakening has the effect of suppressing current period results in relation to the comparable prior period, while yen strengthening has the effect of magnifying current period results in relation to the comparable prior period. A significant portion of the Company’s business is conducted in yen and never converted into dollars but translated into dollars for U.S. GAAP reporting purposes, which results in foreign currency impact to earnings, cash flows and book value on a U.S. GAAP basis. Management evaluates the Company's financial performance both including and excluding the impact of foreign currency translation to monitor, respectively, cumulative currency impacts and the currency-neutral operating performance over time. The average yen/dollar exchange rate is based on the published MUFG Bank, Ltd. telegraphic transfer middle rate (TTM).

The Company defines the non-U.S. GAAP financial measures included in this document as follows:

• Adjusted book value is the U.S. GAAP book value (representing total shareholders’ equity), less AOCI as recorded on the U.S. GAAP balance sheet. Adjusted book value per common share is adjusted book value at the period end divided by the ending outstanding common shares for the period presented. The Company considers adjusted book value and adjusted book value per common share important as they exclude AOCI, which fluctuates due to market movements that are outside management’s control. The most comparable U.S. GAAP financial measures for adjusted book value and adjusted book value per common share are total book value and total book value per common share, respectively.

• Adjusted book value including unrealized foreign currency translation gains and losses is adjusted book value plus unrealized foreign currency translation gains and losses. Adjusted book value including unrealized foreign currency translation gains and losses per common share is adjusted book value plus unrealized foreign currency translation gains and losses at the period end divided by the ending outstanding common shares for the period presented. The Company considers adjusted book value including unrealized foreign currency translation gains and losses, and its related per share financial measure, important as they exclude certain components of AOCI, which fluctuate due to market movements that are outside management's control; however, it includes the impact of foreign currency as a result of the significance of Aflac’s Japan operation. The most comparable U.S. GAAP financial measures for adjusted book value including unrealized foreign currency translation gains and losses and adjusted book value including unrealized foreign currency translation gains and losses per common share are total book value and total book value per common share, respectively.

• Adjusted book value including unrealized foreign currency translation gains and losses and pension liability adjustment is adjusted book value plus unrealized foreign currency translation gains and losses and pension liability adjustment. The Company considers adjusted book value including unrealized foreign currency translation gains and losses and pension liability adjustment important as it excludes certain components of AOCI, which fluctuates due to market movements that are outside management's control; however, it includes the impact of foreign currency as a result of the significance of Aflac’s Japan operation. The most comparable U.S. GAAP financial measure for adjusted book value including unrealized foreign currency translation gains and losses and pension liability adjustment is total book value.

• Adjusted debt is the sum of notes payable, as recorded on the U.S. GAAP balance sheet, excluding 50% of subordinated debentures and perpetual bonds and all pre-funding of debt maturities. The Company considers adjusted debt important as it measures outstanding debt consistently with expectations of the Company’s rating agency stakeholders. The most comparable U.S. GAAP financial measure for adjusted debt is notes payable.

• Adjusted debt including 50% of subordinated debentures and perpetual bonds is the sum of notes payable, as recorded on the U.S. GAAP balance sheet, excluding pre-funding of debt maturities. The Company considers adjusted debt including 50% of subordinated debentures and perpetual bonds important as it measures outstanding debt consistently with expectations of the Company’s rating agency stakeholders. The most comparable U.S. GAAP financial measure for adjusted debt including 50% of subordinated debentures and perpetual bonds is notes payable.

• Adjusted earnings are adjusted revenues less benefits and adjusted expenses. Adjusted earnings per share (basic or diluted) are the adjusted earnings for the period divided by the weighted average outstanding shares (basic or diluted) for the period presented. The adjustments to both revenues and expenses account for certain items that cannot be predicted or that are outside management’s control. Adjusted revenues are U.S. GAAP total revenues excluding adjusted net investment gains and losses. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest cash flows from derivatives associated with notes payable but excluding any nonrecurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company's underlying business performance. Management uses adjusted earnings and adjusted earnings per diluted share to evaluate the financial performance of the Company’s insurance operations on a consolidated basis and believes that a presentation of these financial measures is vitally important to an understanding of the underlying profitability drivers and trends of the Company’s insurance business. The most comparable U.S. GAAP financial measures for adjusted earnings and adjusted earnings per share (basic or diluted) are net earnings and net earnings per share, respectively.

• Adjusted earnings excluding current period foreign currency impact are computed using the average foreign currency exchange rate for the comparable prior-year period, which eliminates fluctuations driven solely by foreign currency exchange rate changes. Adjusted earnings per diluted share excluding current period foreign currency impact is adjusted earnings excluding current period foreign currency impact divided by the weighted average outstanding diluted shares for the period presented. The Company considers adjusted earnings excluding current period foreign currency impact and adjusted earnings per diluted share excluding current period foreign currency impact important because a significant portion of the Company's business is conducted in Japan and foreign exchange rates are outside management’s control; therefore, the Company believes it is important to understand the impact of translating foreign currency (primarily Japanese yen) into U.S. dollars. The most comparable U.S. GAAP financial measures for adjusted earnings excluding current period foreign currency impact and adjusted earnings per diluted share excluding current period foreign currency impact are net earnings and net earnings per share, respectively.

• Amortized hedge costs/income represent costs/income incurred or recognized as a result of using foreign currency derivatives to hedge certain foreign exchange risks in the Company's Japan segment or in Corporate and other. These amortized hedge costs/ income are estimated at the inception of the derivatives based on the specific terms of each contract and are recognized on a straight-line basis over the term of the hedge. The Company believes that amortized hedge costs/income measure the periodic currency risk management costs/income related to hedging certain foreign currency exchange risks and are an important component of net investment income. There is no comparable U.S. GAAP financial measure for amortized hedge costs/ income.

• Adjusted net investment gains and losses are net investment gains and losses adjusted for i) amortized hedge cost/income related to foreign currency exposure management strategies and certain derivative activity, ii) net interest cash flows from foreign currency and interest rate derivatives associated with certain investment strategies, which are both reclassified to net investment income, and iii) the impact of interest cash flows from derivatives associated with notes payable, which is reclassified to interest expense as a component of total adjusted expenses. The Company considers adjusted net investment gains and losses important as it represents the remainder amount that is considered outside management’s control, while excluding the components that are within management’s control and are accordingly reclassified to net investment income and interest expense. The most comparable U.S. GAAP financial measure for adjusted net investment gains and losses is net investment gains and losses.

• Adjusted net investment income is net investment income adjusted for i) amortized hedge cost/income related to foreign currency exposure management strategies and certain derivative activity, and ii) net interest cash flows from foreign currency and interest rate derivatives associated with certain investment strategies, which are reclassified from net investment gains and losses to net investment income. The Company considers adjusted net investment income important because it provides a more comprehensive understanding of the costs and income associated with the Company’s investments and related hedging strategies. The most comparable U.S. GAAP financial measure for adjusted net investment income is net investment income.

• Adjusted return on equity is adjusted earnings divided by average shareholders’ equity, excluding accumulated other comprehensive income (AOCI). Management uses adjusted return on equity to evaluate the financial performance of the Company’s insurance operations on a consolidated basis and believes that a presentation of this financial measure is vitally important to an understanding of the underlying profitability drivers and trends of the Company’s insurance business. The Company considers adjusted return on equity important as it excludes components of AOCI, which fluctuate due to market movements that are outside management's control. The most comparable U.S. GAAP financial measure for adjusted return on equity is return on average equity (ROE) as determined using net earnings and average total shareholders’ equity.
