U.S. Revolver

In Fiscal 2014, we amended and restated our existing credit agreement (Amended Credit Agreement) with a major domestic bank. We entered into this Amended Credit Agreement to, among other things, allow for the payment of dividends and to extend the expiration date of the facility. The Amended Credit Agreement provides for a $75.0 million revolving credit facility (U.S. Revolver). Obligations are collateralized by the stock of certain of our subsidiaries.

The interest rate for amounts outstanding under the Amended Credit Agreement for 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 1.75%, as determined by our consolidated leverage ratio, 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 $21.5 million for our outstanding letters of credit at September 30, 2014.

There were no borrowings outstanding under the U.S. Revolver as of September 30, 2014. Amounts available under the U.S. Revolver were $53.5 million at September 30, 2014. The U.S. Revolver expires on December 31, 2018.

The Amended Credit Agreement contains certain restrictive and maintenance-type covenants, such as restrictions on the amount of capital expenditures allowed. 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.

The Amended Credit Agreement is collateralized by a pledge of 100% of the voting capital stock of each of our domestic subsidiaries and 66% of the voting capital stock of each non-domestic subsidiary, excluding Powell Canada. The Amended Credit Agreement 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 Amended Credit Agreement) occurs and is continuing, on the terms and subject to the conditions set forth in the Amended Credit Agreement, amounts outstanding under the Amended Credit Agreement may be accelerated and may become immediately due and payable. As of September 30, 2014, we were in compliance with all of the financial covenants of the Amended Credit Agreement.

Canadian Revolver

We have a $9.0 million credit agreement with a major international bank in Canada (the Canadian Revolver) to provide working capital support and letters of credit for our operations in Canada. The Canadian Revolver provides for the issuance of letters of credit which reduce the amounts that may be borrowed under this revolver. There were no outstanding letters of credit at September 30, 2014.

There were no borrowings outstanding under the Canadian Revolver as of September 30, 2014 and amounts available under the Canadian Revolver were $9.0 million at September 30, 2014. The Canadian Revolver expires on February 28, 2015. The interest rate for amounts outstanding under the Canadian Revolver is a floating interest rate based upon either the Canadian Prime Rate, or the lender’s Bankers’ Acceptance Rate. Once the applicable rate is determined, a margin of 0.50% to 1.75%, as determined by our consolidated leverage ratio, is added to the applicable rate.

The principal financial covenants are consistent with those described in our Amended Credit Agreement. The Canadian Revolver contains a “material adverse effect” clause. A “material adverse effect” is defined as a material change in the operations of Powell or Powell Canada in relation to our financial condition, property, business operations, expected net cash flows, liabilities or capitalization.

The Canadian Revolver is secured by the assets of our Canadian operations and provides for customary events of default and carries cross-default provisions with our existing debt agreements. If an event of default (as defined in the Canadian Revolver) occurs and is continuing, per the terms and subject to the conditions set forth in the Canadian Revolver, amounts outstanding under the Canadian Revolver may be accelerated and may become immediately due and payable. As of September 30, 2014, we were in compliance with all of the financial covenants of the Canadian 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 June 30, 2014. 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. At September 30, 2014, the balance in the restricted sinking fund was approximately $0.4 million and was recorded in cash and cash equivalents. 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 0.20% as of September 30, 2014.
