The Company’s top ten customers accounted for approximately 32.9%, 40.4%, and 46.4% of consolidated revenues for the years ended December 31, 2018, 2017 and 2016, respectively. For the year ended December 31, 2017, one T&D customer accounted for 10.7% of our revenues. For the years ended December 31, 2018 and 2016, no single customer accounted for more than 10.0% of annual revenues. </div></div><div style="font-family: 'times new roman', 'serif';font-size: 10pt;margin-bottom: 0;margin-top: 6pt;text-indent: 0.28in;"><div style="color: rgb(0, 0, 0); font-family: "times new roman", serif; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">The Company grants trade credit under contractual payment terms, generally without collateral, to its customers, which include high credit quality electric utilities, governmental entities, general contractors and builders, owners and managers of commercial and industrial properties. Consequently, the Company is subject to potential credit risk related to changes in business and economic factors. However, the Company generally has certain statutory lien rights with respect to services provided. Under certain circumstances such as foreclosures or negotiated settlements, the Company may take title to the underlying assets in lieu of cash in settlement of receivables. As of December 31, 2018 and 2017, none of our customers individually exceeded 10.0% of accounts receivable. The Company believes the terms and conditions in its contracts, billing and collection policies are adequate to minimize the potential credit risk. </div></div><div style="font-family: 'times new roman', 'serif';font-size: 10pt;margin-bottom: 0;margin-top: 6pt;text-indent: 0.28in;"><div style="color: rgb(0, 0, 0); font-family: "times new roman", serif; font-size: 10pt; letter-spacing: 0px; top: 0px;;display:inline;">As of December 31, 2018, approximately 88% of the Company’s craft labor employees were covered by collective bargaining agreements. Although the majority of these agreements prohibit strikes and work stoppages, the Company cannot be certain that strikes or work stoppages will not occur in the future. </div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table>
