Effective December 20, 2016, the Company amended its revolving credit facility to extend the termination date, reduce LIBOR interest margin, and to modify certain financial and other covenants in order to meet the ongoing needs of the Company's business and to allow for greater flexibility in relation to future acquisitions.

The Company maintains an unsecured revolving credit facility with certain lenders under its Amended and Restated Revolving Credit Agreement ("Agreement"). The aggregate commitments from lenders under this Agreement are $250,000,000 and, subject to certain conditions, the Company has the option to request an increase in aggregate commitments of up to an additional $50,000,000. The Agreement requires us to maintain various financial covenants including a minimum earnings before interest and tax to interest expense ratio, a maximum leverage ratio, and a minimum asset coverage ratio. The Agreement also contains various covenants relating to limitations on indebtedness, limitations on investments and acquisitions, limitations on sale of properties, and limitations on liens and capital expenditures. The Agreement also contains other customary covenants, representations and events of defaults. The expiration date of the revolving credit facility is December 20, 2021. As of December 31, 2017, $60,000,000 was outstanding under the Agreement. On December 31, 2017, $1,655,000 of the revolver capacity was committed to irrevocable standby letters of credit issued in the ordinary course of business as required by vendors' contracts resulting in $188,345,000 in available borrowings.

The aggregate maturities of long-term debt, as of December 31, 2017, are as follows: $82,000 in 2018; zero in 2019 and 2020; $60,000,000 in 2021; and zero thereafter.

The carrying value of our debt approximates the fair value as of December 31, 2017 and 2016, as our borrowings bear interest based upon short-term floating market interest rates. The fair value measurement for these liabilities is categorized as Level 2 in the fair value hierarchy. Fair values determined by Level 2 utilize inputs that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
