9.	DEBT AGREEMENTS

On December 7, 2012, we entered into an agreement, which was subsequently amended on May 9, 2014, June 5, 2014, December 5, 2014 and December 6, 2016 (as amended, the “U.S. credit agreement”) with a financial institution that provided us with an unsecured revolving credit and letter of credit facility. The U.S. credit agreement contains customary financial covenants, including covenants (1) restricting us from making certain investments, loans, advances and acquisitions (but permitting us to make investments in subsidiaries of up to $5.0 million), (2) requiring that we maintain a minimum working capital, and (3) requiring that we maintain a minimum tangible net worth. The U.S. credit agreement permits us to pay certain cash dividends, so long as we are not in default under the U.S. credit agreement before and after giving effect to such dividends.

Borrowings under our U.S. credit agreement bear interest either at a LIBOR-based rate or a floating rate, in each case with an interest rate floor of 0.00%. The floating rate equals 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, (c) the prevailing prime rate and (d) 0.00%. The rate we must pay for that portion of the U.S. credit agreement which is not utilized is 0.05% per annum.

On December 6, 2016, we entered into a fourth amendment to our U.S. credit agreement to, among other things, increase the unsecured revolving credit facility from $12.5 million to $15.0 million, to increase the cash dividend allowance from $4.0 million per calendar year to $5.0 million per calendar year, and to extend the scheduled maturity date to December 31, 2018. The U.S. credit agreement, as amended, provides for the issuance of up to $5.0 million in letters of credit. We also amended the U.S. credit agreement to increase the minimum working capital and minimum tangible net worth requirements from $90.0 million to $105.0 million and $120.0 million to $125.0 million, respectively.

On February 16, 2017, we amended our credit facility in China to decrease the credit facility from 40.0 million Chinese Yuan to 20.0 million Chinese Yuan (approximately $3.2 million). On February 14, 2018, we renewed this facility with an expiration date of February 13, 2019. We had $1.6 million and $1.5 million of borrowings under our China credit facility at each of April 30, 2018 and October 31, 2017, respectively, which bears interest at variable rates of 4.7% and 4.4% annually, respectively. We also have a £1.0 million revolving credit facility in the United Kingdom and a €1.5 million revolving credit facility in Germany. 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, 2018, we had unutilized credit facilities of $19.8 million.
