​ 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: ​
