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, 2016 and December 31, 2015, respectively:



	March 31, 2016				December 31, 2015
Federal Government	$	4,794	4	%	$	4,230	4	%
State Governments	812		1	%	1,274		1	%
Local Governments	20,204		18	%	19,660		18	%
Private Companies	87,335		77	%	82,627		77	%
Total receivables	$	113,145	100	%	$	107,791	100	%

At March 31, 2016 and December 31, 2015, respectively, no single customer accounted for more than 10% of total current receivables.

Additionally, the table below represents concentrations of revenue by type of customer for the three months ended March 31, 2016 and 2015, respectively:



	Three months ended March 31,
	2016		%		2015		%
Federal	$	4,156	3	%	$	12,312	15	%
State	5,367		4	%	9,631		12	%
Local	19,677		15	%	21,292		26	%
Private	100,423		78	%	38,220		47	%
Total contract revenues	$	129,623	100	%	$	81,455	100	%

In the three months ended March 31, 2016, no single customer generated more than 10% of total contract revenues. In the three months ended March 31, 2015, the United States Army Corps of Engineers (USACOE) generated 10.6% of total contract revenues.

The Company does not believe that the loss of any one of its 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.

In addition, the commercial concrete construction segment primarily purchases concrete from select suppliers. The loss of one of these suppliers could adversely impact short-term operations.
