The Company has a revolving credit facility (“Credit Facility”) with a capacity of $450 million, as of June 30, 2016. On May 16, 2016 the Company entered into an eighth amendment to the Credit Facility ("Eighth amendment"), which increased the size of the Credit Facility from $300 million to $450 million. The Credit Facility has an expansion feature which can be increased up to an additional $150 million limited by a borrowing base primarily consisting of eligible accounts receivable and inventories. All obligations under the Credit Facility are secured by first priority liens on substantially all of the Company’s present and future assets. The terms of the Credit Facility permit prepayment without penalty at any time (subject to customary breakage costs with respect to LIBOR or CDOR based loans prepaid prior to the end of an interest period). In addition, the Eighth amendment allows for unlimited stock repurchases and dividends, as long as the Company meets certain credit availability percentages and fixed charge coverage ratios.

The Credit Facility matures in May 2020. The Company incurred fees of approximately $0.6 million in connection with the Eighth amendment.

Amounts borrowed, outstanding letters of credit and amounts available to borrow, net of certain reserves required under the Credit Facility, were as follows (in millions):



	June 30, 2016		December 31, 2015
Amounts borrowed	$	220.0	$	47.0
Outstanding letters of credit and other commitments	41.1		18.5
Amounts available to borrow⁽¹⁾	188.9		123.9
