We have a revolving credit facility (“Credit Facility”) with a capacity of $200 million which is expandable up to an additional $100 million of lenders' revolving commitments, subject to certain provisions. On May 30, 2013, we entered into a fifth amendment to our Credit Facility (the "Fifth Amendment"), which extended the term of our Credit Facility from May 2016 to May 2018 and reduced the margin on LIBOR or CDOR borrowings and the unused facility fees. The margin added to LIBOR or CDOR is a range of 125 to 175 basis points, down from a range of 175 to 225 basis points. The Fifth Amendment established our basket for permitted stock repurchases at $50 million, not to exceed $15 million in any year, and re-established a $75 million ceiling for dividends allowable over the term of the Credit Facility. At the date of signing the Fifth Amendment, we incurred fees of approximately $0.3 million, which are being amortized over the term of the amendment.

All obligations under the Credit Facility are secured by first priority liens upon substantially all of our 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).

The Credit Facility contains restrictive covenants, including among others, limitations on dividends and other restricted payments, other indebtedness, liens, investments and acquisitions and certain asset sales. As of June 30, 2013, we were in compliance with all of the covenants under the Credit Facility.

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,		December 31,
	2013		2012
Amounts borrowed	$	47.0	$	73.3
Outstanding letters of credit	$	21.9	$	19.8
Amounts available to borrow ⁽¹⁾	$	120.9	$	97.7

Average borrowings during the three and six months ended June 30, 2013 were $41.4 million and $37.9 million, respectively, with amounts borrowed, at any one time, ranging from zero to $112.0 million.

Our weighted-average interest rate was calculated based on our daily cost of borrowing, which was computed on a blend of prime and LIBOR rates.

We paid total unused facility fees and letter of credit participation fees, which are included in interest expense, of $0.2 million and $0.5 million during the three and six months ended June 30, 2013 and 2012, respectively. Amortization of debt issuance costs is included in interest expense. Unamortized debt issuance costs were $1.6 million as of June 30, 2013 and $1.5 million as of December 31, 2012.
