Commitments And Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Note 10 – Commitments and contingencies: Legal proceedings. We are involved, from time to time, in various environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to our business. We currently believe the disposition of all claims and disputes, individually or in the aggregate, should not have a material long-term adverse effect on our consolidated financial condition, results of operations or liquidity. Environmental matters and litigation. Our operations are governed by various federal, state and local environmental laws and regulations. Our policy is to comply with environmental laws and regulations at all of our facilities and to continually strive to improve environmental performance in association with applicable industry initiatives. We believe our operations are in substantial compliance with applicable requirements of environmental laws. From time to time, we may be subject to environmental regulatory enforcement under various statutes, resolution of which typically involves the establishment of compliance programs. Income taxes. From time to time, we undergo examinations of our income tax returns, and tax authorities have or may propose tax deficiencies. We believe we have adequately provided accruals for additional income taxes and related interest expense which may ultimately result from such examinations and we believe that the ultimate disposition of all such examinations should not have a material adverse effect on our consolidated financial position, results of operations or liquidity. We are a party to a tax sharing agreement with Contran and NL providing for the allocation of tax liabilities and tax payments as described in Note 1. Under applicable law, we, as well as every other member of the Contran Tax Group, are each jointly and severally liable for the aggregate federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which we are included in the Contran Tax Group. NL has agreed, however, to indemnify us for any liability for income taxes of the Contran Tax Group in excess of our tax liability in accordance with the tax sharing agreement. Concentration of credit risk. Our products are sold primarily in North America to original equipment manufacturers. Our ten largest customers accounted for approximately 47% of sales in 2019, 48% in 2020 and 51% in 2021. One customer of the Security Products segment accounted for 14% of consolidated sales in 2019, 17% in 2020 and 16% in 2021.
