Based on the current level of availability based on the covenant calculations, the Company’s remaining borrowing capacity was approximately $395 million as of June 30, 2018. As of June 30, 2018, the Company was in compliance with all covenants and conditions under its Credit Agreement. Letters of Credit As of June 30, 2018, outstanding letters of credit under the Credit Agreement totaled $3.8 million and primarily guaranteed workers’ compensation and other insurance related obligations. As of June 30, 2018, letters of credit and contract performance guarantees issued outside of the Credit Agreement totaled $1.8 million. Legal Proceedings From time to time, the Company has been involved in legal actions, both as plaintiff and defendant, which arise in the ordinary course of business. The Company accrues for exposures associated with such legal actions to the extent that losses are deemed both probable and reasonably estimable. To the extent specific reserves have not been made for certain legal proceedings, their ultimate outcome, and consequently, an estimate of possible loss, if any, cannot reasonably be determined at this time. Based on currently available information and advice received from counsel, the Company believes that the disposition or ultimate resolution of any current legal proceedings, except as otherwise specifically reserved for in its financial statements, will not have a material adverse effect on the Company’s financial position, cash flows or results of operations.
