Accounting Standards Update and Change in Accounting Principle [Abstract] |
Accounting Policies and Recent Accounting Pronouncements | Accounting Policies and Recent Accounting Pronouncements There have been no material changes in our significant accounting policies from those described in our combined 2024 Form 10-K, except discussed below. Cash and Cash Equivalents and Restricted Cash The table below provides a reconciliation of cash, cash equivalents and restricted cash reported in the Condensed Consolidated Balance Sheets to the amount reported in the Condensed Statements of Consolidated Cash Flows:
| June 30, 2025 |  | December 31, 2024
| CenterPoint Energy |  | Houston Electric |  | CERC |  | CenterPoint Energy |  | Houston Electric |  | CERC
| (in millions)
Cash and cash equivalents (1) | $ | 93 |  |  | $ | 15 |  |  | $ | — |  |  | $ | 24 |  |  | $ | 14 |  |  | $ | 2 |
Restricted cash included in Prepaid expenses and other current assets (2) | 6 |  |  | — |  |  | — |  |  | 6 |  |  | — |  |  | — |
Total cash, cash equivalents and restricted cash shown in Condensed Statements of Consolidated Cash Flows | $ | 99 |  |  | $ | 15 |  |  | $ | — |  |  | $ | 30 |  |  | $ | 14 |  |  | $ | 2 |
(1)Cash and cash equivalents related to VIEs as of June 30, 2025 and December 31, 2024 included $22 million and $21 million, respectively, at CenterPoint Energy and $15 million and $14 million, respectively, at Houston Electric. (2)Restricted cash primarily related to accounts established by CenterPoint Energy in connection with the issuance of the Securitization Bonds to collateralize the Securitization Bonds that were issued in these financing transactions. These restricted cash accounts are not available for withdrawal until the maturity of the Securitization Bonds. Recent Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). This ASU enhances the transparency of income tax disclosures related to rate reconciliation and income taxes. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Registrants are currently evaluating the impact of this ASU on their respective consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures (“ASU 2024-03”). This ASU improves disclosure of a public business entity’s expense by requiring disaggregated disclosure of expenses in commonly presented expense captions. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and for interim periods beginning after December 15, 2027. Early adoption is permitted. The Registrants are currently evaluating the impact of this ASU on their respective consolidated financial statements. Management believes that all other recently adopted and recently issued accounting standards that are not yet effective will not have a material impact on the Registrants’ financial position, results of operations or cash flows upon adoption.
