Long-Term Debt

On June 8, 2012, we entered into the Fifth Amended Credit Agreement. The Fifth Amended Credit Agreement provides us with a $200.0 million revolving credit facility that expires on June 8, 2017 and includes a swingline sub facility of $20.0 million and a $75.0 million sub facility for letters of credit. The Fifth Amended Credit Agreement also provides a $200.0 million term loan facility that matures on June 8, 2017, $192.5 million of which remained outstanding on March 31, 2013, and an uncommitted incremental accordion facility of $200.0 million. As of March 31, 2013, availability under the revolving credit facility totaled $82.6 million as calculated under the most restrictive covenant.

Borrowings under the Fifth Amended Credit Agreement generally bear interest at variable rates based on a margin or spread in excess of either (1) the one-month, two-month, three-month or six-month rate (or with the approval of affected lenders, nine-month or twelve-month rate) for Eurodollar deposits ("LIBOR") or (2) the greatest of (a) the SunTrust Bank prime lending rate, (b) the federal funds rate plus 0.50%, and (c) one-month LIBOR plus 1.00% (the "Base Rate"), as selected by the Company. The LIBOR margin varies between 1.75% and 3.00%, and the Base Rate margin varies between 0.75% and 2.00%, depending on our leverage ratio. The Fifth Amended Credit Agreement also provides for an annual fee ranging between 0.30% and 0.50% of the unused commitments under the revolving credit facility. Extensions of credit under the Fifth Amended Credit Agreement are secured by guarantees from all of the Company's active domestic subsidiaries and by security interests in substantially all of the Company's and such subsidiaries' assets.

On February 5, 2013, we entered into a First Amendment to the Fifth Amended Credit Agreement, which included, among other things, a temporary increase in the LIBOR and Base Rate margins of 0.25%. The increased margins are effective through December 31, 2013 and apply only in the event that our total funded debt to EBITDA ratio is greater than or equal to 3.50 to 1.00.

We are required to repay outstanding revolving loans under the revolving credit facility in full on June 8, 2017. We are required to repay term loans in quarterly principal installments aggregating (1) 1.250% of the original aggregate principal amount of the term loans during each of the eight quarters beginning with the quarter ended September 30, 2012, (2) 1.875% of the original aggregate principal amount of the term loans during each of the next four quarters beginning with the quarter ending September 30, 2014, and (3) 2.500% of the original aggregate principal amount of the term loans during each of the remaining quarters prior to maturity on June 8, 2017, at which time the entire unpaid principal balance of the term loans is due and payable.

The Fifth Amended Credit Agreement contains financial covenants that require us to maintain specified ratios or levels of (1) total funded debt to EBITDA and (2) fixed charge coverage. As of March 31, 2013, we were in compliance with all of the financial covenant requirements of the Fifth Amended Credit Agreement.

The Fifth Amended Credit Agreement contains various other affirmative and negative covenants that are typical for financings of this type. Among other things, the Fifth Amended Credit Agreement limits repurchases of the Company's common stock and the amount of dividends that the Company can pay to holders of its common stock.
