Concentration of Risk and Enterprise Wide Disclosures

Concentration of Risk and Enterprise Wide Disclosures

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 receivables (trade and retainage) at September 30, 2013 and December 31, 2012, respectively:

	September 30, 2013				December 31, 2012

Private Companies	35,897		67	%	38,617		73	%
Total receivables	$	53,392	100	%	$	53,285	100	%

At September 30, 2013, no single customer represented more than 10% of total receivables. At December 31, 2012, two private sector customers accounted for 11.7% and 9.9% of total receivables, respectively.

Additionally, the table below represents concentrations of revenue by type of customer for the three and nine months ended September 30, 2013, and 2012.

In the three months ended September 30, 2013, a private customer generated 11.9% of revenues and the US Army Corps of Engineers ("USCOE") generated 9.3% of total revenues. In the three months ended September 30, 2012, a private sector customer generated 11.5% of revenues while the USCOE generated 19.5% of total revenues. For the nine month periods ended September 30,2013 and 2012, the USCOE generated 13.7% and 16.8% of total revenues, respectively. Also in the nine month period ended September 30, 2012, a private sector customer generated 12.6% of total revenues.

The Company does not believe that the loss of any one of these customers, other than the USCOE, would have a material adverse effect on the Company and its subsidiaries and affiliates.
