U.S. Revolver

We have a $75.0 million revolving credit facility (U.S. Revolver) to provide working capital support and letters of credit. In June 2017, we entered into the Third Amendment to the Credit Agreement (the Third Amendment). The Third Amendment, among other things, (i) extended the Maturity Date from December 2018 to June 2022; (ii) amended the definition of Applicable Rate by (a) providing that Pricing Level I shall apply when a Cash Collateral Period (described below) is in effect and that Pricing Level II shall apply when no Cash Collateral Period is in effect, (b) decreasing the Letter of Credit Fee percentage for Pricing Level I from 1.00% to 0.875% and (c) increasing the Commitment Fee percentage for both Pricing Level I and Pricing Level II from 0.1875% to 0.20%; (iii) added a new requirement that during a Cash Collateral Period we maintain a cash balance in a pledged cash collateral account equal to at least 102% of the Outstanding Amount of Revolving Loans and Letter of Credit Obligations and (iv) modified the Financial Covenants by requiring that, during any Cash Collateral Period, the Consolidated Current Ratio be no less than 1.10 to 1.0. Price Level 3 in the prior agreement was removed and our ability to pay dividends remains subject to financial covenant restrictions.

Generally, a Cash Collateral Period under the Third Amendment is defined as a fiscal quarter during which we have pledged our cash collateral account to the Administrative Agent. A Cash Collateral Period will terminate on the last day of the fiscal quarter in which we satisfy the Level II Pricing Covenants set forth in the Third Amendment for two consecutive fiscal quarters. If we are not in compliance with the Level II Pricing Covenants, we are subject to Level I Pricing Covenants.

The Cash Collateral Period was in effect as of September 30, 2017; therefore, we have placed $24.9 million in a pledged cash collateral account, which was approximately 102% of our outstanding letters of credit as of September 30, 2017. 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 September 30, 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 provides for the issuance of letters of credit which reduce the amounts that may be borrowed under this revolver. The amount available under the U.S. Revolver was reduced by $24.1 million for our outstanding letters of credit at September 30, 2017. There were no borrowings outstanding under the U.S. Revolver as of September 30, 2017. Amounts available under the U.S. Revolver were $50.9 million at September 30, 2017. The U.S. Revolver expires on June 27, 2022.

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, as well as by the pledged cash collateral account during any Cash Collateral Period. 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. As of September 30, 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 September 30, 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 1.19% as of September 30, 2017.
