Revolving Credit Agreement [Abstract]

8.	Revolving Credit Agreement

The Company has a $350 million syndicated credit agreement ("Credit Agreement") that extends to June 21, 2016. Interest on the borrowings under the Credit Agreement accrue at variable rates, based upon LIBOR or a defined "Base Rate," both determined based upon the rating of the Company's senior unsecured long-term debt (the "Debt Rating"). The applicable margin to be added to LIBOR ranges from 0.65% to 1.95% (1.20% as of March 31, 2012), and for Base Rate-determined loans, from 0.0% to 0.95% (0.00% as of March 31, 2012). The Company also pays a quarterly facility fee ranging from 0.10% to 0.45% (0.20% as of March 31, 2012), determined based upon the Debt Rating, of the $350 million commitment under the Credit Agreement. In addition, the Company must pay certain letter of credit fees, ranging from 0.65% to 1.95% (1.20% as of March 31, 2012), with respect to letters-of-credit issued under the Credit Agreement. The Company has the right to voluntarily prepay and reborrow loans and to terminate or reduce the commitments under the facility. As of March 31, 2012, the Company had $5.9 million of issued letters of credit under the Credit Agreement, with the balance of $344.1 million available for future borrowings.

The Company is subject to certain financial and restrictive covenants under the Credit Agreement, which, among other things, require the maintenance of a minimum interest coverage ratio (3.5 to 1.0 for March 31, 2012). The interest coverage ratio is defined in the Credit Agreement as, for any period, the ratio of consolidated earnings before interest, taxes, depreciation and amortization, and non-cash net pension expense ("EBITDA") to consolidated interest expense for such period. The Credit Agreement also requires the Company to maintain a debt to capital ratio of less than 55%. The debt to capital ratio is defined in the Credit Agreement as the ratio of consolidated indebtedness, as defined therein, to consolidated capitalization, as defined therein. As of March 31, 2012, the Company was in compliance with all of the covenants of the Credit Agreement.
