Regulation | Regulation Our distribution and pipeline and storage operations are subject to regulation with respect to rates, service, maintenance of accounting records, and various other matters by the respective regulatory authorities in the states in which we operate, which creates regulatory assets and liabilities that are recovered from or refunded to customers over time through the ratemaking process. Substantially all of our regulatory assets are recorded as a component of other current assets and deferred charges and other assets and our regulatory liabilities are recorded as a component of other current liabilities and deferred credits and other liabilities. Deferred gas costs are recorded either in other current assets or liabilities and the long-term portion of regulatory excess deferred taxes and regulatory cost of removal obligation are reported separately. Significant regulatory assets and liabilities as of September 30, 2024 and 2023 included the following:
(1)Infrastructure mechanisms in Texas, Louisiana, and Tennessee allow for the deferral of all eligible expenses associated with capital expenditures incurred pursuant to these rules, including the recording of interest on the deferred expenses until the next rate proceeding (rate case or annual rate filing), at which time investment and costs would be recovered through base rates. (2)Regulatory excess deferred taxes represent changes in our net deferred tax liability related to our cost of service ratemaking due to the enactment of the Tax Cuts and Jobs Act of 2017 (the "TCJA") and a Kansas legislative change enacted in fiscal 2020. See Notes 13 and 15 to the consolidated financial statements for further information. (3)In APT's general rate case settlement in December 2023, the RRC approved a new annual compliance filing that allows APT to recover certain system safety and integrity costs incurred each year. Costs above a specified benchmark are deferred onto the balance sheet as incurred. Once the filing is approved by the RRC, the revenue and expense are recognized over 12 months resulting in no impact to operating income. Securitization Kansas See Note 10 to the consolidated financial statements for securitization and other information related to Atmos Energy Kansas Securitization I, LLC (AEK). Texas In Texas, we recorded a $2.02 billion regulatory asset in fiscal 2021 for costs incurred during Winter Storm Uri. In 2021, the Texas Legislature passed House Bill 1520, which authorized the RRC to issue a statewide securitization financing order directing the Texas Public Finance Authority (TPFA) to issue bonds (customer rate relief bonds) for gas utilities that chose to participate to recover extraordinary costs incurred to secure gas supply and to provide service during Winter Storm Uri, and to restore gas utility systems after that event, thereby providing rate relief to customers by extending the period during which these extraordinary costs would otherwise be recovered and supporting the financial strength and stability of gas utility companies. In March 2023, the Texas Natural Gas Securitization Finance Corporation (the Finance Corporation), with the authority of the TPFA, issued $3.5 billion in customer rate relief bonds with varying scheduled final maturities from 12 to 18 years. The bonds are obligations of the Finance Corporation, payable from the customer rate relief charges and other bond collateral, and are not an obligation of Atmos Energy. We collected $2.02 billion of this amount and relieved the regulatory asset. We began collecting the customer rate relief charges on October 1, 2023, and any such property collected is solely owned by the Finance Corporation and not available to pay creditors of Atmos Energy. Additionally, we deferred $32.4 million in carrying costs incurred after September 1, 2022. During fiscal 2024, we have recovered $22.0 million of this amount. Of the remaining $10.4 million, $4.0 million has been recorded as a current asset in other current assets as of September 30, 2024 and $6.4 million has been recorded as a long-term asset in deferred charges and other assets as of September 30, 2024 as we anticipate recovering this amount in future regulatory proceedings.
