Domestic and Multi-Currency Line

On March 30, 2011, the Company entered into a new credit agreement for up to $330.0 million of credit with a group of commercial banks (the "Original Credit Agreement"). On November 29, 2011, the Company amended the Credit Agreement, to increase the amount available by $100.0 million, to $430.0 million (the "Credit Agreement"). The Credit Agreement consists of a $380.0 million line of credit, which includes the ability to borrow up to $50.0 million in specified foreign currencies or U.S. dollars (the "Domestic and Multi-currency Line") and a $50.0 million term loan facility (the "2015 Variable Rate Notes"). The line of credit commitment amount will decrease by $100.0 million, to $280.0 million, on the earlier of May 29, 2013 or the second business day following the closing of the proposed initial public offering of common stock of Enova. if it generates at least $350.0 million in net proceeds. See Note 12 for further discussion of this transaction. Interest on the Domestic and Multi-currency Line is charged, at the Company's option, at either the London Interbank Offered Rate ("LIBOR") plus a margin varying from 2.00% to 3.25%, or at the agent's base rate plus a margin varying from 0.50% to 1.75%. Interest on the 2015 Variable Rate Notes is charged, at the Company's option, at either LIBOR plus a margin of 3.50% or at the agent's base rate plus a margin of 2.00%. The margin for the Domestic and Multi-currency Line is dependent on the Company's cash flow leverage ratios as defined in the Credit Agreement. The Company also pays a fee on the unused portion of the Domestic and Multi-currency Line ranging from 0.25% to 0.50% (0.38% at March 31, 2012) based on the Company's cash flow leverage ratios. The weighted average interest rate (including margin) on the Domestic and Multi-currency Line and the 2015 Variable Rate Notes, respectively, was 3.03% and 3.75% at March 31, 2012. The Domestic and Multi-currency Line matures on March 31, 2015. The 2015 Variable Rate Notes require quarterly principal payments of $2.1 million with any outstanding principal remaining due at maturity on March 31, 2015.

At March 31, 2012 and 2011, borrowings under the Company's Domestic and Multi-currency Line consisted of four pricing tranches with maturity dates ranging from three to 31 days. However, the Company routinely refinances borrowings pursuant to the terms of its Domestic and Multi-currency Line. Therefore, these borrowings are reported as part of the applicable line of credit and as long-term debt.

Other

On March 30, 2011, in conjunction with the establishment of the Original Credit Agreement, the Company entered into a separate credit agreement for the issuance of $20.0 million in letters of credit (the "Letter of Credit Facility"). The Company had standby letters of credit of $18.1 million issued under the Letter of Credit Facility at March 31, 2012.

Each of the Company's credit agreements and senior unsecured notes require the Company to maintain certain financial ratios. As of March 31, 2012, the Company was in compliance with all covenants or other requirements set forth in its debt agreements.
