The Company is involved in environmental remediation and monitoring activities at its Randolph, Wisconsin manufacturing facility and accrues for related costs when such costs are determined to be probable and estimable. The Company expenses annual costs of remediation, which have ranged from $47,000 to $56,000 per year over the past five years. The Company’s estimated liability for these costs is $916,000 at May 31, 2015 and 2014, measured on an undiscounted basis over an estimated period of 15 years; $50,000 of the liability is recorded within current liabilities and the remainder is recorded within other long term liabilities in the consolidated balance sheet. The Company has agreements with unrelated third parties that provide for the payment of license fees and royalties on the sale of certain products. Royalty expense under the terms of these agreements was $2,189,000, $2,278,000 and $1,837,000 for fiscal years 2015, 2014 and 2013, respectively. Some of these agreements provide for guaranteed minimum royalty payments to be paid each fiscal year by the Company for certain technologies. Future minimum royalty payments are as follows: 2016—$643,000, 2017—$634,000, 2018—$659,000, and 2019—$659,000. The Company leases office and manufacturing facilities under non-cancelable operating leases. Rent expense for fiscal years 2015, 2014 and 2013 was $736,000, $856,000 and $657,000, respectively. Future fiscal year minimum rental payments for these leases over their remaining terms are as follows: 2016—$424,000, 2017—$161,000, 2018—$161,000, 2019—$85,200, and 2020 and later—$62,400. The Company is subject to certain legal and other proceedings in the normal course of business that, in the opinion of management, should not have a material effect on its future results of operations or financial position.
