(1) Certain amounts have been reclassified 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 and Other long-term liabilities on the consolidated balance sheets. As of December 31, 2018, and September 30, 2018, the carrying amount of the interest rate swap liabilities reported in Accounts payable and accrued liabilities was approximately $75 million and $77 million, respectively. See Note 13 —Derivatives Not Receiving Hedge Accounting Treatment — Interest Rate Derivatives for information regarding the interest rate swap liabilities.

Gallatin Coal Combustion Residual Facilities Liability. The estimated cost of the potential Gallatin CCR project is approximately $900 million. The current and long-term portions of the resulting obligation are reported in Accounts payable and accrued liabilities and Other long-term liabilities, respectively, on TVA's consolidated balance sheets. As of December 31, 2018, and September 30, 2018, related liabilities of $23 million and $30 million, respectively, were recorded in Accounts payable and accrued liabilities. See Note 8 for information regarding the Gallatin CCR facilities.

EnergyRight^®Financing Obligation. TVA purchases certain loans receivable from its LPCs in association with the EnergyRight^® Solutions 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. The carrying amount of the financing obligation reported in Accounts payable and accrued liabilities for both December 31, 2018, and September 30, 2018, was approximately $25 million. See Note 5 for information regarding the associated loans receivable.

Paradise Pipeline Financing. TVA reserves firm pipeline capacity on an approximately 19 mile pipeline owned by Texas Gas, which serves TVA’s Paradise Combined Cycle Plant. The capacity contract contains a lease component because of TVA’s exclusive right to use the pipeline. Because TVA was initially involved in the construction of the pipeline as a result of funding certain FERC filing fees prior to construction, TVA was considered the owner of the pipeline during the construction period for accounting purposes. Due to TVA’s continuing involvement in the pipeline after the construction period, TVA accounted for the transaction as a financing transaction. This amount is shown in Other long-term liabilities in the December 31, 2018, and September 30, 2018, Consolidated Balance Sheets.

Accrued Long-Term Service Agreement. TVA has entered into various long-term service agreements for major maintenance activities at certain of TVA’s combined cycle plants. TVA uses the direct expense method of accounting for these arrangements and accrues for parts when TVA takes ownership, and for contractor services when they are rendered. Under certain of these arrangements, parts received and services rendered exceed payments made. As a result, TVA has recorded an accrued long-term service agreement obligation in Other long-term liabilities in the December 31, 2018, and September 30, 2018, Consolidated Balance Sheets.
