Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies Disclosure | Commitments and Contingent Liabilities 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. Changes in the product warranty accrual for the nine months ended March 31, 2021 and 2020 were as follows:
| Nine Months Ended
| March 31
(Amounts in Thousands) | 2021 |  | 2020
Product warranty liability at the beginning of the period | $ | 647 |  |  | $ | 958 |
Additions to warranty accrual (including changes in estimates) | (31) |  |  | (269) |
Settlements made (in cash or in kind) | (58) |  |  | (30) |
Product warranty liability at the end of the period | $ | 558 |  |  | $ | 659 |
