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 March 31, 2014 and December 31, 2013, respectively:

	March 31, 2014				December 31, 2013
Federal Government	$	4,937	12	%	$	4,849	10	%
State Governments	1,741		4	%	4,002		8	%
Local Governments	11,188		27	%	8,857		18	%
Private Companies	23,067		57	%	31,829		64	%
Total receivables	$	40,933	100	%	$	49,537	100	%

At March 31, 2014, a private sector customer, a local port authority and the US Army Corps of Engineers ("USCOE") represented 12.1%, 12.1% and 10.7% of total receivables, respectively. At December 31, 2013, a private sector customer accounted for 9.9% of total receivables.

Additionally, the table below represents concentrations of revenue by type of customer for the three months ended March 31, 2014 and 2013.

	Three months ended March 31,
	2014		%		2013		%
Federal	$	11,897	15	%	$	20,031	27	%
State	6,911		8	%	6,219		8	%
Local	13,505		17	%	17,234		23	%
Private	48,945		60	%	31,575		42	%
	$	81,258	100	%	$	75,059	100	%

In the three months ended March 31, 2014, a private customer generated 14.3% of revenues and the USCOE generated 13.8% of total revenues. In the three months ended March 31, 2013, the USCOE generated 11.7% 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.
