As discussed above in the section “Non-GAAP Financial Measures,” in addition to financial measures determined in accordance with U.S. GAAP, we believe our non-GAAP financial measures, which are not a substitute for U.S. GAAP and may not be consistent with similarly titled non-GAAP financial measures used by other companies, provide meaningful information and are useful to investors because management evaluates performance based on these metrics for purposes of (i) establishing corporate goals; (ii) budgeting and forecasting; (iii) comparing period-to-period operating results, analyzing changes in results and identifying potential trends; (iv) monitoring our overall leverage and credit ratings; and (v) making compensation decisions. In addition, certain of the financial covenants in our committed bank revolving line of credit agreements and debt indentures are based on non-GAAP financial measures. Below we discuss each of the non-GAAP financial measures and provide a reconciliation of our non-GAAP financial measures to the most comparable U.S. GAAP financial measures.

Statements of Operations Non-GAAP Financial Measures

One of our primary performance measures is TIER, which is a measure indicating our ability to cover the interest expense requirements on our debt. TIER is calculated by adding the interest expense to net income and dividing that total by the interest expense. We adjust the TIER calculation to add the derivative cash settlements income (expense) to the interest expense and to remove the derivative forward value gains (losses) from total net income. Adding the cash settlements income (expense) back to interest expense also has a corresponding effect on our adjusted net interest income.

We use derivatives to manage interest rate risk on our funding of the loan portfolio. The derivative cash settlements income (expense) represents the amount that we receive from or pay to our counterparties based on the interest rate indexes in our derivatives that do not qualify for hedge accounting. We adjust the reported interest expense to include the derivative cash settlements income (expense). We use the adjusted cost of funding to set interest rates on loans to our members and believe that the interest expense adjusted to include derivative cash settlements income (expense) represents our total cost of funding for the period. TIER, calculated by adding the derivative cash settlements income (expense) to the interest expense, reflects management’s perspective on our operations and, therefore, we believe that it represents a useful financial measure for investors.

The derivative forward value gains (losses) do not represent our cash inflows or outflows during the current period and, therefore, do not affect our current ability to cover our debt service obligations. The derivative forward value gains (losses) included in the derivative gains (losses) line of the statement of operations represents a present-value estimate of the future cash inflows or outflows that will be recognized as net cash settlements income (expense) for all periods through the maturity of our derivatives that do not qualify for hedge accounting. For operational management and decision-making purposes, we subtract derivative forward value gains (losses) from our net income when calculating TIER and for other net income presentation purposes. In addition, since the derivative forward value gains (losses) do not represent current-period cash flows, we do not allocate such funds to our members.

Net Income and Adjusted Net Income

Table 33 provides a reconciliation of adjusted interest expense, adjusted net interest income and adjusted net income to the comparable U.S. GAAP financial measures. These adjusted financial measures are used in the calculation of our adjusted net interest yield and adjusted TIER.

Table 33: Adjusted Net Income

(1)Represents primarily the net periodic contractual interest income amount on our interest rate swaps during the reporting period.

(2)Represents the change in fair value of our interest rate swaps during the reporting period due to changes in expected future interest rates over the remaining life of our derivative contracts.

We primarily fund our loan portfolio through the issuance of debt. However, we use derivatives as economic hedges as part of our strategy to manage the interest rate risk associated with funding our loan portfolio. We therefore consider the interest income and expense incurred on our derivatives to be part of our funding cost in addition to the interest expense on our debt. As such, we add net periodic derivative cash settlements interest income and expense amounts to our reported interest expense to derive our adjusted interest expense and adjusted net interest income. We exclude unrealized derivative forward value gains (losses) from our adjusted net income.

TIER and Adjusted TIER

Table 34 displays the calculation of our TIER and adjusted TIER.

Table 34: TIER and Adjusted TIER

(1) TIER is calculated based on our net income (loss) plus interest expense for the period divided by interest expense for the period.

(2) Adjusted TIER is calculated based on adjusted net income (loss) plus adjusted interest expense for the period divided by adjusted interest expense for the period.

Debt Outstanding and Equity and Adjusted Debt Outstanding and Equity

Adjusted debt-to-equity ratio is one of the key measures in managing our business and is used for: (i) establishing corporate goals; (ii) budgeting and forecasting; and (iii) monitoring our overall leverage and credit ratings. We therefore believe that this adjusted financial measure, in combination with the comparable U.S. GAAP financial measure, is useful to investors in evaluating our financial condition. We adjust the comparable U.S. GAAP financial measure to:

•exclude from total debt outstanding, and add to total equity, 100% of members’ subordinated certificates;

•exclude from total debt outstanding, and add to total equity, 50% of subordinated deferrable debt; and

•exclude from total equity the noncash cumulative impact of changes in derivative forward value gains (losses), historical foreign currency translation adjustments, and the amounts of AOCI.

Members’ subordinated certificates are accounted for as debt under U.S. GAAP. These subordinated certificates are held only by our members and are subordinated to all senior and nonmember subordinated indebtedness of CFC. The members’ subordinated certificates have long-dated maturities and in certain cases pay no interest or pay interest that is below market. Under certain conditions we are prohibited from making interest payments to members on the subordinated certificates. Given the subordinated certificates’ equity-like characteristics, we subtract 100% of members’ subordinated certificates from total debt outstanding and add them to total equity when calculating our adjusted debt-to-equity ratio.

We issue subordinated deferrable debt in the capital markets with maturities of up to 45 years including the option to defer interest payments. The characteristics of subordination, deferrable interest and long-dated maturity are all equity-like characteristics. Since the subordinated deferrable debt is issued in the capital markets and not just to members of CFC and it ranks higher in subordination compared with members’ subordinated certificates, we subtract 50% of our subordinated deferrable debt from total debt outstanding and add it to total equity. This approach more closely aligns with the rating agencies’ methodology for calculating the adjusted debt-to-equity ratio.

We record derivative instruments at fair value on our consolidated balance sheets. Our total equity includes the noncash impact of derivative forward value gains (losses) and historical foreign currency translation adjustments recorded in net income. We have not issued foreign-denominated debt since 2007, and as of May 31, 2026 and 2025, there were no foreign currency derivative instruments outstanding. It also includes as a component of AOCI the impact of changes in the fair value of derivatives designated as cash flow hedges as well as the unrealized gains (losses) on the defined benefit pension plan. In evaluating our adjusted debt-to-equity ratio, we make adjustments to equity similar to the adjustments made in calculating TIER. We exclude from total equity the noncash cumulative impact of changes in derivative forward value gains (losses), historical foreign currency translation adjustments, and the amounts of AOCI, which reflects management’s perspective on our operations and, therefore, we believe, is a useful financial measure for investors.

Table 35 provides a reconciliation between our total debt outstanding and total equity and the adjusted amounts used in the calculation of our adjusted debt-to-equity ratio as of May 31, 2026 and 2025.

Table 35: Adjusted Total Debt Outstanding and Equity

(1)Total debt outstanding includes our interest-bearing debt and excludes non-interest-bearing liabilities, such as derivative liabilities.

(2)Represents consolidated total derivative forward value gains (losses). The cumulative amounts also include historical foreign currency translation adjustments recorded in net income.

Debt-to-Equity and Adjusted Debt-to-Equity Ratios

Table 36 displays the calculations of our debt-to-equity and adjusted debt-to-equity ratios as of May 31, 2026 and 2025.

Table 36: Debt-to-Equity Ratio and Adjusted Debt-to-Equity Ratio

(1)Calculated based on total debt outstanding at period end divided by total equity at period end.

(2) See Table 35 above for details on the calculation of these non-GAAP financial measures and the reconciliation to the most comparable U.S. GAAP financial measures.

(3)Calculated based on adjusted total debt outstanding at period end divided by adjusted total equity at period end.

Total CFC Equity and Members’Equity

Members’ equity excludes the noncash impact of derivative forward value gains (losses), historical foreign currency adjustments recorded in net income, and amounts recorded in AOCI. Because these amounts generally have not been realized, they are not available to members and are excluded by the CFC Board of Directors in determining the annual allocation of adjusted net income to patronage capital, to the members’ capital reserve and to other member funds. Table 37 provides a reconciliation of members’ equity to total CFC equity as of May 31, 2026 and 2025. We present the components of AOCI in “Note 11—Equity.”

Table 37: Members’ Equity

(1)Represents period-end cumulative derivative forward value gains and historical foreign currency translation adjustments recorded in net income for CFC only, as total CFC equity does not include the noncontrolling interest of the variable interest entity, which we are required to consolidate. We report the separate results of operations for CFC in “Note 16—Business Segments.” The period-end cumulative derivative forward value total gain amounts as of May 31, 2026 and 2025 are presented above in Table 35.
