Commitments and Contingent Liabilities [Abstract] |
Commitments and Contingencies Disclosure | Commitments and Contingent Liabilities Standby letters of credit may be issued to third-party suppliers and insurance institutions and can only be drawn upon in the event of the Company’s failure to pay its obligations to a beneficiary. As of September 30, 2017, we had a maximum financial exposure from unused standby letters of credit totaling $0.4 million. We don’t expect circumstances to arise that would require us to perform under any of these arrangements and believe that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect our condensed consolidated financial statements. Accordingly, no liability has been recorded as of September 30, 2017 with respect to the standby letters of credit. The Company also may enter into commercial letters of credit to facilitate payments to vendors and from customers. The Company’s China operation, 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, our China operation would be required to satisfy the obligation with the transferee and the draft would revert back to our China operation. At September 30, 2017, 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. 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, 2017 and 2016 were as follows:
| Three Months Ended
| September 30
(Amounts in Thousands) | 2017 |  | 2016
Product warranty liability at the beginning of the period | $ | 593 |  |  | $ | 605 |
Additions to warranty accrual (including changes in estimates) | 47 |  |  | 170 |
Settlements made (in cash or in kind) | (53 | ) |  | (142 | )
Product warranty liability at the end of the period | $ | 587 |  |  | $ | 633 |
