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 September 30, 2014 and December 31, 2013, respectively:

	September 30, 2014				December 31, 2013
Federal Government	$	1,014	2	%	$	4,849	10	%
State Governments	2,532		5	%	4,002		8	%
Local Governments	14,171		30	%	8,857		18	%
Private Companies	29,900		63	%	31,829		64	%
Total receivables	$	47,617	100	%	$	49,537	100	%

At September 30, 2014, a private sector customer and a local port authority represented 25.8% and 10.2% 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 and nine months ended September 30, 2014 and 2013.

	Three months ended September 30,								Nine months ended September 30,
	2014		%		2013		%		2014		%		2013		%

In the three months ended September 30, 2014, one private customer generated 11.5% of revenues. In the three months ended September 30, 2013, the United States Army Corps of Engineers (USACOE) generated 9.3% of total revenues. In the nine months ended September 30, 2014, one private customer generated 9.7% of revenues. For the nine months ended September 30, 2013 the USACOE generated 13.7% of total 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 over time.
