(a)The Companies’ policy is to review the fair value hierarchy and recognize transfers into and transfers out of the levels at the end of each reporting period. Con Edison and CECONY had $7 million of commodity derivative liabilities transferred from level 3 to level 2 during the three months ended March 31, 2023 because of availability of observable market data due to the decrease in the terms of certain contracts from beyond three years as of December 31, 2022 to less than three years as of March 31, 2023. Con Edison and CECONY had an immaterial amount of derivative liabilities and $10 million and $9 million of commodity derivative assets, respectively, transferred from level 3 to level 2 during the year ended December 31, 2022 because of availability of observable market data due to the decrease in the terms of certain contracts from beyond three years as of September 30, 2022 to less than three years as of December 31, 2022. (b)Level 2 assets and liabilities include investments held in the deferred compensation plan and/or non-qualified retirement plans, exchange-traded contracts where there is insufficient market liquidity to warrant inclusion in Level 1, and certain over-the-counter derivative instruments for electricity, refined products and natural gas. Derivative instruments classified as Level 2 are valued using industry standard models that incorporate corroborated observable inputs, such as pricing services or prices from similar instruments that trade in liquid markets, time value and volatility factors. (c)The accounting rules for fair value measurements and disclosures require consideration of the impact of nonperformance risk (including credit risk) from a market participant perspective in the measurement of the fair value of assets and liabilities. At March 31, 2023 and December 31, 2022, the Companies determined that nonperformance risk would have no material impact on their financial position or results of operations. (d)Other assets are comprised of assets such as life insurance contracts within the deferred compensation plan and non-qualified retirement plans. (e)Amounts represent the impact of legally-enforceable master netting agreements that allow the Companies to net gain and loss positions and cash collateral held or placed with the same counterparties. (f)See Note N. (g)On March 1, 2023, Con Edison completed the sale of substantially all of the assets of the Clean Energy Businesses. See Note S and Note T.
