Commitments and Contingencies Disclosure [Abstract] |
Product Warranties | The Company provides only assurance-type warranties for a limited time period, which cover workmanship and assures the product complies with specifications provided by or agreed upon with the customer. We maintain a provision for limited warranty repair or replacement of products manufactured and sold, which has been established in specific manufacturing contract agreements. We estimate product warranty liability at the time of sale based on historical repair or replacement cost trends in conjunction with the length of the warranty offered. Management refines the warranty liability periodically based on changes in historical cost trends and in certain cases where specific warranty issues become known.
