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, 2016 and December 31, 2015, respectively:



	September 30, 2016				December 31, 2015
Federal Government	$	812	1	%	$	4,230	5	%

Total receivables	$	126,400	100	%	$	93,398	100	%

At September 30, 2016 and December 31, 2015 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 and nine months ended September 30, 2016 and 2015, respectively:



	Three months ended September 30,								Nine months ended September 30,
	2016		%		2015		%		2016		%		2015		%
Federal	$	13,268	8	%	$	10,629	8	%	$	25,200	6	%	$	34,302	11	%

Total contract revenues	$	164,017	100	%	$	137,061	100	%	$	433,941	100	%	$	304,607	100	%

In the three and nine months ended September 30, 2016 and 2015, no single customer generated more than 10% 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.
