Accounts receivable include amounts billed to governmental agencies and private customers and do not bear interest. Balances billed to customers but not paid pursuant to retainage provisions generally become payable upon contract completion and acceptance by the owner. The table below presents the concentrations of current receivables (trade and retainage) at September 30, 2015 and December 31, 2014, respectively:

In the three months ended September 30, 2015, no single customer generated more than 10% of total contract revenues. In the three months ended September 30, 2014, one private customer generated 11.5% of total contract revenues. In the nine months ended September 30, 2015, no single customer generated more than 10% of total contract revenues. In the nine months ended September 30, 2014, one private customer generated 9.7% of total contract revenues.

The Company does not believe that the loss of any one of these customers would have a material adverse effect on the Company or its subsidiaries and affiliates, since no single specific customer sustains such a large portion of receivables or contract revenue over time.

In addition, the commercial concrete construction segment primarily purchases concrete from select suppliers. The loss of one of these suppliers could adversely impact short-term operations.
