Concentration of Risk and Enterprise Wide Disclosures

4.Concentration of Risk and Enterprise Wide Disclosures

Accounts receivable in both reportable segments 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 accounts receivable from customers (trade and retainage) at March 31, 2021 and December 31, 2020, respectively:

	March 31, 2021				December 31, 2020
Federal Government	$	4,341	3	%	$	4,826	4	%
State Governments		220	-	%		—	-	%
Local Governments		22,444	17	%		17,823	13	%
Private Companies		103,914	79	%		110,616	83	%
Gross receivables		130,919	99	%		133,265	100	%
Allowance for credit losses		(323)				(411)
Net receivables	$	130,596			$	132,854

At March 31, 2021 one customer in the Private Companies category accounted for 10.6% of total current receivables. At December 31, 2020, no single customer accounted for more than 10.0% of total current receivables.

Additionally, the table below represents concentrations of contract revenue by type of customer for the three months ended March 31, 2021 and 2020, respectively:

	Three months ended March 31,
	2021		%		2020		%
Federal Government	$	12,764	8	%	$	5,319	3	%
State Governments		168	-	%		12,232	7	%
Local Government		33,516	22	%		52,012	31	%
Private Companies		106,861	70	%		97,057	59	%
Total contract revenues	$	153,309	100	%	$	166,620	100	%

In the three months ended March 31, 2021 and 2020, no single customer exceeded 10.0% 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.

The concrete segment primarily purchases concrete from select suppliers. The loss of any one of these suppliers could adversely impact short-term operations.

Contract revenues generated outside the United States totaled 1.6% and 2.4% of total revenues for the three months ended March 31, 2021 and 2020, and were primarily located in the Caribbean Basin and Mexico.
