6. Long-Term Debt

On October 21, 2011, we entered into a senior credit agreement, which we refer to as the credit agreement, with a syndicate of lenders led by JPMorgan Chase Bank, N.A., as administrative agent, that provides for an unsecured revolving credit facility of up to $250,000 in loan commitments with letter of credit and swing line loan sublimits of $25,000 each. We may from time to time, so long as no default or event of default has occurred and is continuing, increase the loan commitments under the credit agreement by up to $150,000 by adding new commitments or increasing the commitment of willing lenders. The maturity date of the credit agreement is October 21, 2016.

Any borrowings under the facility will bear interest at LIBOR plus 1.25% to 1.50%, depending on our leverage ratio, which is the ratio of our consolidated total indebtedness to our consolidated earnings before interest, taxes, depreciation and amortization ("EBITDA").As of December 31, 2011, the weighted-average interest rate on outstanding borrowings was 1.64%. We must also pay a commitment fee of 0.175% to 0.225% depending on our leverage ratio.

The credit agreement contains financial and other covenants, including but not limited to (1) limitations on our incurrence of additional indebtedness and liens, the consummation of certain fundamental changes, investments and restricted payments, and the amount of consolidated capital expenditures that we may make in each of our fiscal years ending June 30, 2012 through 2016 and (2) financial covenants calculated on a trailing twelve month basis that:

•

our consolidated leverage ratio will not exceed 3.5 times our trailing twelve-month, or TTM, consolidated EBITDA;

•

our consolidated senior leverage ratio, which is the ratio of our consolidated indebtedness that is not subordinated to our indebtedness under the credit agreement to our TTM consolidated EBITDA, will not exceed 2.75 times our TTM consolidated EBITDA; and

•

our interest coverage ratio, which is the ratio of our TTM consolidated EBITDA to our TTM consolidated interest expense, will be at least 3.0.

As of December 31, 2011, we were in compliance with all financial covenants under the credit agreement. Availability under our credit facility consisted of the following:


	December 31, 2011
Maximum aggregate available borrowing amount	$	250,000
Outstanding borrowings (1)		(146,500	)
Stand-by letters of credit		(294	)

Maximum additional available borrowing amount	$	103,206

(1)	Amounts outstanding under the credit facility are not due until maturity (October 21, 2016). Amounts outstanding from overnight borrowings under the credit facility of $6,000 have been classified as current liabilities.
