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 current receivables (trade and retainage) at March 31, 2015 and December 31, 2014, respectively:

	March 31, 2015				December 31, 2014
Federal Government	$	4,376	10	%	$	4,607	9	%
State Governments	1,346		3	%	476		1	%
Local Governments	13,517		32	%	13,927		26	%
Private Companies	23,159		55	%	33,778		64	%
Total receivables	$	42,398	100	%	$	52,788	100	%

At March 31, 2015, a private sector customer represented 16.2% of total trade receivables. At December 31, 2014, a private sector customer accounted for 14.0% of total trade receivables.

Additionally, the table below represents concentrations of revenue by type of customer for the three months and three months ended March 31, 2015 and 2014.

	Three months ended March 31,
	2015		%		2014		%
Federal	$	12,312	15	%	$	11,897	15	%
State	9,631		12	%	6,911		8	%
Local	21,292		26	%	13,505		17	%
Private	38,220		47	%	48,945		60	%
	$	81,455	100	%	$	81,258	100	%

In the three months ended March 31, 2015, the United States Army Corps of Engineers (USACOE) generated 10.6% of total contract revenues. In the three months ended March 31, 2014, a private customer generated 14.3% of total contract revenues and the USACOE generated 13.8% 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.
