Change in Accounting Estimate, Description						Change in Estimates: The Company reviews the estimated useful lives of its fixed assets on an ongoing basis. In evaluating useful lives, the Company considers how long assets will remain functionally efficient and effective, given levels of technology, competitive factors, and the economic environment. If the assessment indicates that the assets will continue to be used for a longer period than previously anticipated, the useful life of the assets is revised, resulting in a change in estimate. Changes in estimates are accounted for on a prospective basis by depreciating the assets’ current carrying values over their revised remaining useful lives. In fiscal year 2022, a review indicated that Surface Mount Technology production equipment had actual lives that were longer than previously estimated.
