​ Under certain utility contracts, the Company periodically receives cash deposits to be held in trust for the payment of energy incentive rebates to be sent directly to the utility’s end-customer on behalf of the utility. The Company acts solely as the utility’s agent to distribute these funds to the end-customer and, accordingly, the Company classifies these contractually restricted funds as restricted cash. Because these funds are held in trust for pass through to the utility’s customers and have no impact on the Company’s working capital or operating cash flows, these cash receipts are presented in the consolidated statement of cash flows as financing cash inflows, “Receipt of restricted cash”, with the subsequent payments classified as financing cash outflows, “Payment of restricted cash.” Accounts Receivable Accounts receivable consisted of the following: ​

​ Billed accounts receivable represent amounts billed to clients that have yet to be collected. Unbilled accounts receivable represent revenue recognized, but not yet billed, pursuant to contract terms or accounts billed after the period end. Substantially all unbilled receivables as of December 30, 2022 are, or were expected to be, billed and collected within twelve months of such date. Contract retentions represent amounts invoiced to clients where payments have been withheld pending the completion of certain milestones, other contractual conditions or upon the completion of the project. These retention agreements vary from project to project and could be outstanding for several months. Allowances for doubtful accounts have been determined through specific identification of amounts considered to be uncollectible and potential write-offs, plus a non-specific allowance for other amounts for which some potential loss has been determined to be probable based on current and past experience.
