U.S. Revolver

We have a $75.0 million revolving credit facility (U.S. Revolver) to provide working capital support and letters of credit which expires on June 27, 2022. The amount available under the U.S. Revolver at December 31, 2017 was reduced by $27.0 million for our outstanding letters of credit. There were no loans outstanding under the U.S. Revolver as of December 31, 2017. Amounts available under the U.S. Revolver were $48.0 million at December 31, 2017.

Per the terms of the U.S. Revolver, we are required to maintain a cash balance in a pledged cash collateral account equal to 102% of the outstanding amount of any loans and letter of credit obligations until we meet certain financial ratios. As of December 31, 2017, the balance in the pledged account was $27.8 million. The cash collateral associated with the outstanding letters of credit that are due to expire beyond twelve months has been classified as non-current restricted cash on the balance sheet as of December 31, 2017.

The interest rate for amounts outstanding under the U.S. Revolver is a floating rate based upon the higher of the Federal Funds Rate plus 0.5%, the bank’s prime rate, or the Eurocurrency rate plus 1.00%. Once the applicable rate is determined, a margin ranging up to 1.25% is added to the applicable rate.

The U.S. Revolver is collateralized by a pledge of 100% of the voting capital stock of each of our domestic subsidiaries and 65% of the voting capital stock of each non-domestic subsidiary. The U.S. Revolver provides for customary events of default and carries cross-default provisions with other existing debt agreements. If an event of default (as defined in the U.S. Revolver) occurs and is continuing, on the terms and subject to the conditions set forth in the U.S. Revolver, amounts outstanding under the U.S. Revolver may be accelerated and may become immediately due and payable. It also contains financial covenants defining various financial measures and the levels of these measures with which we must comply, as well as a “material adverse change” clause. A “material adverse change” is defined as a material change in our operations, business, properties, liabilities or condition (financial or otherwise) or a material impairment of our ability to perform our obligations under our credit agreements. As of December 31, 2017, we were in compliance with all of the financial covenants of the U.S. Revolver.

Industrial Development Revenue Bonds

We borrowed $8.0 million in October 2001 through a loan agreement funded with proceeds from tax-exempt industrial development revenue bonds (Bonds). These Bonds were issued by the Illinois Development Finance Authority and were used for the completion of our Northlake, Illinois facility. Pursuant to the Bond issuance, a reimbursement agreement between us and a major domestic bank required an issuance by the bank of an irrevocable direct-pay letter of credit (Bond LC), as collateral, to the Bonds’ trustee to guarantee payment of the Bonds’ principal and interest when due. The Bond LC is subject to both early termination and extension provisions customary to such agreements, as well as various covenants, for which we were in compliance at December 31, 2017. While the Bonds mature in 2021, the reimbursement agreement requires annual redemptions of $0.4 million that commenced on October 25, 2002. A sinking fund is used for the redemption of the Bonds. The Bonds bear interest at a floating rate determined weekly by the Bonds’ remarketing agent, which was the underwriter for the Bonds and is an affiliate of the bank. This interest rate was 1.90% as of December 31, 2017.
