Balances billed to customers but not paid pursuant to retainage provisions generally become payable upon contract completion and acceptance by the owner.

At December 31, 2013, a private sector customer accounted for 9.9% of total receivables. At December 31, 2012, 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, 2013, 2012 and 2011.

In the twelve months ended December 31, 2013, the US Army Corps of Engineers generated 11.7% of total revenues. In the year ended December 31, 2012, the US Army Corps of Engineers represented 16.7% of total revenues, and a private sector customer generated 10.7% of total revenues. The US Army Corps of Engineers represented 24% of contract revenues in the year ended December 31, 2011.

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 8.5%, 4% and 1% of total revenues for the years ended 2013, 2012 and 2011, respectively and were primarily located in the Caribbean.

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