Note (1) At September 30, 2021, $5 million and $19 million previously classified as Long-term deferred revenue (a component of Other long-term liabilities) and Other (a component of Other long-term liabilities), respectively, were reclassified to Advances for construction (a component of Other long-term liabilities) to conform with current year presentation. Interest Rate Swap Liabilities. TVA uses interest rate swaps to fix variable short-term debt to a fixed rate. The values of these derivatives are included in Accounts payable and accrued liabilities, Accrued interest, and Other long-term liabilities on the Consolidated Balance Sheets. At September 30, 2022 and 2021, the carrying amount of the interest rate swap liabilities reported in Accounts payable and accrued liabilities and Accrued interest was $54 million and $115 million, respectively. See Note 15 — Risk Management Activities and Derivative Transactions — Derivatives Not Receiving Hedge Accounting Treatment — Interest Rate Derivative s for information regarding the interest rate swap liabilities. As of September 30, 2022, interest rate swap liabilities (including current portion) decreased $734 million as compared to September 30, 2021, primarily due to increases in market interest rates along with net settlement payments made during the year. Operating Lease Liabilities. TVA's operating leases consist primarily of railcars, equipment, real estate/land, and power generating facilities. At September 30, 2022 and 2021, the current portion of TVA's operating leases reported in Accounts payable and accrued liabilities was $59 million and $40 million, respectively. See Note 8 — Leases for more information regarding leases. Currency Swap Liabilities. To protect against exchange rate risk related to British pound sterling denominated Bond transactions, TVA entered into foreign currency hedges. The values of these derivatives are included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets. At September 30, 2022 and 2021, the carrying amount of the currency swap liabilities reported in Accounts payable and accrued liabilities was $12 million and $7 million, respectively. As of September 30, 2022, currency swap liabilities (including current portion) increased $157 million as compared to September 30, 2021, primarily due to the strengthening of the U.S. dollar against the British pound sterling. See Note 15 — Risk Management Activities and Derivative Transactions — Cash Flow Hedging Strategy for Currency Swaps for more information regarding the currency swap liabilities. EnergyRight® Financing Obligation. TVA purchases certain loans receivable from its LPCs in association with the EnergyRight® program. The current and long-term portions of the resulting financing obligation are reported in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA's Consolidated Balance Sheets. At September 30, 2022 and 2021, the carrying amount of the financing obligation reported in Accounts payable and accrued liabilities was $14 million and $16 million, respectively. See Note 9 — Other Long-Term Assets for information regarding the associated loans receivable. Long-Term Deferred Compensation. TVA provides compensation arrangements to engage and retain certain employees, both executive and non-executive, which are designed to provide participants with the ability to defer compensation to future periods. The current and long-term portions are recorded in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA’s Consolidated Balance Sheets. At September 30, 2022 and 2021, the current amount of deferred compensation recorded in Accounts payable and accrued liabilities was $53 million and $51 million, respectively. Advances for Construction. TVA receives refundable and non-refundable advances for construction that are generally intended to defray all or a portion of the costs of building or extending TVA’s existing power assets. Amounts received are deferred as a liability with the long-term portion representing amounts that will not be recognized within the next 12 months. As projects meet milestones or other contractual obligations, the refundable portion is refunded to the customer and the non-refundable portion is recognized as contributions in aid of construction and offsets the cost of plant assets. At September 30, 2022 and 2021, the current amount of advances for construction recorded in Accounts payable and accrued liabilities was $33 million and $38 million, respectively. Long-Term Deferred Revenue. Long-term deferred revenue represents payments received that exceed services rendered resulting in the deferral of revenue. This long-term portion represents amounts that will not be recognized within the next 12 months primarily related to fiber and transmission agreements. The current and long-term portions of the deferral are recorded in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA’s Consolidated Balance Sheets. At September 30, 2022 and 2021, the current amount of deferred revenue recorded in Accounts payable and accrued liabilities was $16 million and $17 million, respectively. Accrued Long-Term Service Agreements. TVA has entered into various long-term service agreements for major maintenance activities at certain of its combined cycle plants. TVA uses the direct expense method of accounting for these arrangements. TVA accrues for parts when it takes ownership and for contractor services when they are rendered. Under certain of these agreements, parts received and services rendered exceed payments made. The current and long-term portions of the resulting obligation are recorded in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA's Consolidated Balance Sheets. At September 30, 2022 and 2021, the current amount of accrued long-term service agreements recorded in Accounts payable and accrued liabilities was $32 million and $28 million, respectively.
