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, 2013 and December 31, 2012, respectively:

	March 31, 2013				December 31, 2012
Federal Government	$	11,794	31	%	$	7,375	14	%
State Governments	194		1	%	1,761		3	%
Local Governments	6,924		17	%	5,532		10	%
Private Companies	19,415		51	%	38,617		73	%
Total receivables	$	38,327	100	%	$	53,285	100	%

At March 31, 2013, the US Army Corps of Engineers and a private sector customer accounted for 16.7%, and 14.8% of total receivables. At December 31, 2012, two private sector customers accounted for 11.7% and 9.9% of total receivables.

Additionally, the table below represents concentrations of revenue by type of customer for the three months ended March 31, 2013, and 2012.

	Three months ended March 31,
	2013		%		2012		%
Federal	$	20,031	27	%	$	12,716	25	%
State	6,219		8	%	7,520		15	%
Local	17,234		23	%	11,116		22	%
Private	31,575		42	%	19,538		38	%
	$	75,059	100	%	$	50,890	100	%

In the three months ended March 31, 2013, the US Army Corps of Engineers generated 13.3% of total revenues. In the three months ended March 31, 2012, the US Army Corps of Engineers represented 21.0% of total revenues.

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

The Company’s long-lived assets are substantially located in the United States.
