In August 2013, the Company entered into a $175.0 million Amended and Restated Credit Agreement with a syndicate of banks. The multi-currency credit agreement, which expires in August 2018, replaced the Company’s then-existing $145.0 million revolving credit facility which would have expired in August 2014. Borrowings under the credit agreement bear interest at a variable rate based on LIBOR plus 125 to 225 basis points depending upon the Company’s leverage ratio, defined below. At December 31, 2013 and March 31, 2013, the Company had no borrowings outstanding under its revolving credit facilities. At December 31, 2013, domestic letters of credit totaled $8.0 million, resulting in available borrowings under the Company’s domestic revolving credit facility of $167.0 million. The Company also maintains credit agreements for its foreign subsidiaries with outstanding short-term borrowings at December 31, 2013 and March 31, 2013 of $35.9 million and $30.6 million, respectively. At December 31, 2013, the Company’s foreign unused lines of credit in Europe, Brazil, China, and India totaled $46.0 million. In aggregate, the Company had total available lines of credit of $213.0 million at December 31, 2013. Provisions in the Company’s revolving credit facility, Senior Note agreements, and various foreign credit agreements require the Company to maintain compliance with various covenants and include certain cross-default clauses. Under the Company’s primary debt agreements in the U.S., the Company is subject to a leverage ratio covenant, which requires the Company to limit its consolidated indebtedness, less a certain portion of the Company’s cash balance, both as defined by the credit agreement, to no more than three and one-quarter times consolidated net earnings before interest, taxes, depreciation, amortization, and certain other adjustments (“Adjusted EBIDTA”). The Company is also subject to an interest expense coverage ratio, which requires the Company to maintain Adjusted EBIDTA of at least three times consolidated interest expense. The Company was in compliance with its debt covenants as of December 31, 2013. The fair value of long-term debt is estimated using discounted future cash flows at rates offered to the Company for similar debt instruments with comparable maturities. At December 31, 2013 and March 31, 2013, the carrying value of Modine’s long-term debt approximated fair value, with the exception of the Senior Notes, which had a fair value of approximately $139.0 million at both December 31, 2013 and March 31, 2013.
