DEBT AGREEMENTS

On December 7, 2012, we entered into an agreement (the “U.S. credit agreement”) with a financial institution that provided us with a $12.5 million unsecured revolving credit and letter of credit facility. The U.S. credit agreement permitted the issuance of up to $3.0 million in letters of credit. On May 9, 2014, the maximum amount for outstanding letters of credit under our U.S. credit agreement was increased from $3.0 million to $5.0 million.

On December 5, 2014, we amended our U.S. credit agreement to increase the cash dividend allowance from $3.0 million per calendar year to $4.0 million per calendar year and to extend the scheduled maturity date to December 7, 2016.

Borrowings under our U.S. credit agreement bear interest at a LIBOR-based rate or a floating rate of 1% above the prevailing prime rate. The floating rate will not be less than the greatest of (a) a one month LIBOR-based rate plus 1.00% per annum, (b) the federal funds effective rate plus 0.50% per annum, or (c) the prevailing prime rate. The rate we must pay for that portion of the U.S. credit agreement which is not utilized is 0.05% per annum.

The U.S. credit agreement contains customary financial covenants, including a covenant that permits us to make investments in subsidiaries of up to $5.0 million, a minimum working capital of $90.0 million and a minimum tangible net worth of $120.0 million. The U.S. credit agreement permits us to pay cash dividends in an amount not to exceed $4.0 million per calendar year, so long as we are not in default before and after giving effect to such dividends.

We have a £1.0 million revolving credit facility in the United Kingdom and a €1.5 million revolving credit facility in Germany. We also have a 40.0 million Chinese Yuan (approximately $6.2 million) credit facility in China that was renewed on February 17, 2016 with an expiration date of February 16, 2017. We had $1.5 million and $1.6 million of borrowings under our China credit facility, which bears interest at 4.9% and 5.6% annually (variable rate), at April 30, 2016 and October 31, 2015, respectively. We had no other debt or borrowings under any of our other credit facilities at either of those dates.

All of our credit facilities are unsecured. At April 30, 2016, we were in compliance with all covenants contained in the related credit agreements and, as of that date, we had unutilized credit facilities of $20.3 million.
