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 December 31, 2012 and December 31, 2011, respectively:

Private Companies	38,617		73	%	14,387		53	%

At December 31, 2012, two private sector customers accounted for 11.7%, and 9.9% of total receivables. At December 31, 2011, receivables from the US Army Corps of Engineers and a private sector customer accounted for 9.1% and 12.5% of total receivables, respectively.

Additionally, the table below represents concentrations of revenue by type of customer for the years ended December 31, 2012, 2011 and 2010.

In the twelve months ended December 31, 2012, the US Army Corps of Engineers and a private sector customer generated 16.7%, and 10.7% of total revenues, respectively. In the year ended December 31, 2011, the US Army Corps of Engineers represented 24.0% of total revenues. The US Army Corps of Engineers and a private sector customer represented 28% and 9.8% of contract revenues in the year ended December 31, 2010.

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.

Revenues generated outside the United States totaled 4%, 1%, and 5% of total revenues for the years ended 2012, 2011 and 2010, respectively and were primarily located in the Caribbean.

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