Product Warranties Disclosures [Abstract] |
Warranty Obligations | Warranty Obligations The Company records the estimated cost of fulfilling product warranties at the time of sale based upon historical costs to fulfill claims. Obligations may also be recorded subsequent to the time of sale whenever specific events or circumstances impacting product quality become known that would not have been taken into account using historical data. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers and third-party contract manufacturers, the Company’s warranty obligation is affected by product failure rates, material usage, and service delivery costs incurred in correcting a product failure. An adverse change in any of these factors may result in the need for additional warranty provisions. Warranty obligations are included in “Accrued expenses” on the Consolidated Balance Sheets. The changes in the warranty obligation were as follows (in thousands):
Balance as of December 31, 2017 | $ | 4,701 |
Provisions for warranties issued during the period | 3,376 |
Fulfillment of warranty obligations | (3,223 | )
Foreign exchange rate changes | (117 | )
Balance as of September 30, 2018 | $ | 4,737 |
