See Note 7 — Other Long-Term Assets for information regarding the associated loans receivable. Long-Term Deferred Compensation.

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.

Advances for Construction.

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 March 31, 2023 and September 30, 2022, the current amount of advances for construction recorded in Accounts payable and accrued liabilities was $55 million and $33 million, respectively.

The current and long-term portions of the deferral are reported in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA’s Consolidated Balance Sheets. At March 31, 2023 and September 30, 2022, the current amount of deferred revenue recorded in Accounts payable and accrued liabilities was $20 million and $16 million, respectively.
