Financial Instruments

6. Financial Instruments

The Company’s financial instruments include cash equivalents, restricted cash, accounts receivable, notes receivable, accounts payable, publicly-registered long-term notes, debentures and other long-term debt.

Cash equivalents are placed primarily in money market funds, money market demand deposit accounts and Eurodollar time deposits. The Company’s cash equivalents have original maturities of less than three months. Due to the short maturity of these investments, they are carried on the consolidated balance sheets at cost, which approximates fair value.

Restricted cash is held in a trust account with a third-party intermediary. Due to the short-term nature of this account, the fair value of restricted cash approximates its carrying value.

Accounts receivable are due from a large number of customers, primarily in the construction industry, and are dispersed across wide geographic and economic regions. No single customer accounted for 10% or more of consolidated total revenues in the three and nine month periods ended September 30, 2020 and 2019. The estimated fair values of accounts receivable approximate their carrying amounts due to the periodic reset of interest rates.

Accounts payable represent amounts owed to suppliers and vendors. The estimated fair value of accounts payable approximates the carrying amount due to the short-term nature of the payables.

The carrying values and fair values of the Company’s long-term debt were $2.63 billion and $2.98 billion, respectively, at September 30, 2020 and $2.77 billion and $2.94 billion, respectively, at December 31, 2019. The estimated fair value of the publicly-registered long-term notes was estimated based on Level 2 of the fair value hierarchy using quoted market prices. The estimated fair value of other borrowings approximate their carrying amounts as the interest rates reset periodically.
