Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies Disclosure | Commitments and Contingent LiabilitiesOne of the Company’s China operations, in limited circumstances, receives banker’s acceptance drafts from customers as settlement for their trade accounts receivable. We in turn may transfer the acceptance drafts to a supplier of ours in settlement of current accounts payable. These drafts contain certain recourse provisions afforded to the transferee under laws of The People’s Republic of China. If a transferee were to exercise its available recourse rights, the draft would revert back to our China operation and we would be required to satisfy the obligation with the transferee. At September 30, 2020, the drafts transferred and outstanding totaled $1.3 million. No transferee has exercised their recourse rights against us. For additional information on banker’s acceptance drafts, see Note 1 – Business Description and Summary of Significant Accounting Policies of Notes to Condensed Consolidated Financial Statements. 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 three months ended September 30, 2020 and 2019 were as follows:
| Three Months Ended
| September 30
(Amounts in Thousands) | 2020 |  | 2019
Product warranty liability at the beginning of the period | $ | 647 |  |  | $ | 958 |
Additions to warranty accrual (including changes in estimates) | 249 |  |  | 24 |
Settlements made (in cash or in kind) | (2) |  |  | (23) |
Product warranty liability at the end of the period | $ | 894 |  |  | $ | 959 |
