Revolving Credit Agreement due 2022

Our Revolving Credit Agreement provides a $400.0 million multi-currency asset-based revolving credit facility (The Revolver). The borrowing base under the Revolver includes eligible accounts receivable; inventory; and property, plant and equipment of certain of our subsidiaries in the U.S., Canada, Germany, and the Netherlands. The maturity date of the Revolver is May 16, 2022. Interest on outstanding borrowings is variable, based upon LIBOR or other similar indices in foreign jurisdictions, plus a spread that ranges from 1.25%-1.75%, depending upon our leverage position. We pay a commitment fee on our available borrowing capacity of 0.25%. In the event we borrow more than 90% of our borrowing base, we are subject to a fixed charge coverage ratio covenant. As of April 1, 2018, we had no borrowings outstanding on the Revolver, and our available borrowing capacity was $333.4 million.
