Accounting Policies [Abstract] |
Summary of Significant Accounting Policies and Other Matters | Summary of Significant Accounting Policies and Other Matters Accounting Policies The accounting policies of Con Edison and its subsidiaries conform to generally accepted accounting principles in the United States of America (GAAP). For the Utilities, these accounting principles include the accounting rules for regulated operations and the accounting requirements of the FERC and the state regulators having jurisdiction. Investments Con Edison's investments consist primarily of the investments of Con Edison Transmission that are accounted for under the equity method and the fair value of the Utilities' supplemental retirement income plan and deferred income plan assets. Con Edison Transmission is considering strategic alternatives with respect to its investment in Mountain Valley Pipeline, LLC (MVP) and both Con Edison Transmission and CECONY are considering strategic alternatives with respect to their investments in Honeoye Storage Corporation. Investment in MVP In June 2024, the Mountain Valley Pipeline, a 303-mile gas transmission pipeline in West Virginia and Virginia, entered service. The project operator is continuing restoration of the right of way and estimates a total project cost of approximatel y $8,100 million (excluding allowance for funds used during construction (AFUDC)). As of September 30, 2025, Con Edison Transmission's interest in MVP, the company that developed the project, is approximately 6.6 percent based on Con Edison Transmission's previous capping of its cash contributions. At September 30, 2025, the carrying value of Con Edison Transmission's investment in MVP was $162 million, and its cash contributions to the joint venture amounted to $530 million. Con Edison records its pro rata share of earnings from its equity investment in MVP, adjusted for accretion of the basis differen ce and income taxes, on its consolidated income statement. Co n Edison's pro rata share of earnings from its equity investment in MVP, adjusted for accretion of the basis difference, was $8 million ($6 million after-tax) and $22 million ($16 million after-tax) for the three and nine months ended September 30, 2025, respectively. Reclassification Certain prior period amounts have been reclassified to conform with the current period presentation. Earnings Per Share Con Edison presents basic and diluted earnings per share (EPS) on the face of its consolidated income statement. Basic EPS is calculated by dividing earnings available to common shareholders (“Net income for common stock” on Con Edison’s consolidated income statement) by the weighted average number of Con Edison common shares outstanding during the period. In the calculation of diluted EPS, weighted average shares outstanding are increased for additional shares that would be outstanding if potentially dilutive securities were converted to common stock. Potentially dilutive securities for Con Edison consist of restricted stock units and deferred stock units for which the average market price of the common shares for the period was greater than the estimated vesting price. For the three and nine months ended September 30, 2025 and 2024, basic and diluted EPS for Con Edison are calculated as follows:
| For the Three Months Ended September 30, | For the Nine Months Ended September 30,
(Millions of Dollars, except per share amounts/Shares in Millions) | 2025 | 2024 | 2025 | 2024
Net income for common stock | $688 | $588 | $1,726 | $1,510
Weighted average common shares outstanding – basic | 360.7 | 346.2 | 356.4 | 345.9
Add: Incremental shares attributable to effect of potentially dilutive securities | 1.2 | 1.3 | 1.2 | 1.3
Adjusted weighted average common shares outstanding – diluted | 361.9 | 347.5 | 357.6 | 347.2
Net Income per common share – basic | $1.91 | $1.70 | $4.84 | $4.37
Net Income per common share – diluted | $1.90 | $1.69 | $4.83 | $4.35
The computation of diluted EPS for the three and nine months ended September 30, 2024 and September 30, 2025 excluded an immaterial amount of performance share awards because of their anti-dilutive effect. Reconciliation of Cash, Temporary Cash Investments and Restricted Cash Cash, temporary cash investments and restricted cash are presented on a combined basis in the Companies’ consolidated statements of cash flows. At September 30, 2025 and 2024, cash, temporary cash investments and restricted cash for Con Edison were as follows; CECONY did not have material restricted cash balances as of September 30, 2025 and 2024:
| At September 30,
| Con Edison
(Millions of Dollars) | 2025 | 2024 (a)
Cash and temporary cash investments | $181 | $93
Restricted cash | 1 | 9
Total cash, temporary cash investments and restricted cash | $182 | $102
(a)On March 1, 2023, Con Edison completed the sale of all of the stock of the Clean Energy Businesses. See Note Q. Con Edison retained one deferred project, Broken Bow II, a 75 MW nameplate capacity wind power project located in Nebraska. Con Edison's restricted cash for the 2024 period primarily included restricted cash of Broken Bow II, which was classified as held for sale as of September 30, 2024. The sale and transfer of Broken Bow II, including the related debt, was completed in January 2025. See N ote Q. Variable Interest Entities The accounting rules for consolidation address the consolidation of a variable interest entity (VIE) by a business enterprise that is the primary beneficiary. A VIE is an entity that does not have a sufficient equity investment at risk to permit it to finance its activities without additional subordinated financial support, or whose equity investors lack the characteristics of a controlling financial interest. The primary beneficiary is the business enterprise that has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and either absorbs a significant amount of the VIE’s losses or has the right to receive benefits that could be significant to the VIE. The Companies enter into arrangements including leases, partnerships and electricity purchase agreements, with various entities. As a result of these arrangements, the Companies retain or may retain a variable interest in these entities. CECONY has an ongoing long-term electricity purchase agreement with Brooklyn Navy Yard Cogeneration Partners, LP, a potential VIE. In 2024, a request was made of this counterparty for information necessary to determine whether the entity was a VIE and whether CECONY is the primary beneficiary; however, the information was not made available. The payments for this contract constitute CECONY’s maximum exposure to loss with respect to the potential VIE.
