(a)Unbilled contract revenue represents accumulated incurred costs and earned profits on contracts (revenue arrangements), which have been recorded as revenue, but have not yet been billed to customers, and which represent contract assets as defined in Topic 606. Substantially all accrued unbilled contract revenue is expected to be collected within one year. Unbilled contract revenue arises from the cost-to-cost method of revenue recognition. Unbilled contract revenue from fixed-price type contracts is converted to billed receivables when amounts are invoiced to customers according to contractual billing terms, which generally occur when deliveries or other performance milestones are completed.

(b)Unearned revenue represents a liability for billings to customers in excess of earned revenue, which are contract liabilities as defined in Topic 606.

(c)Additions for unbilled contract revenue and subtractions for unearned revenue represent additional revenue earned. Additions for unearned revenue and subtractions for unbilled contract revenue represent billings. Activity also includes appropriate balance sheet classification for the period. Of the subtractions in 2023, $21 million and $1 million relate to the sale of the Clean Energy Businesses for unbilled contract revenue and unearned revenue, respectively. See (e) below.

(d)Of the subtractions from unearned revenue, $3 million was included in the balances as of January 1, 2023.

(e)Following the sale of the Clean Energy Businesses, Con Edison received substantially all contract revenue, net of certain costs incurred, for a battery storage project located in Imperial County, California. See Note Q.
