Accounting Policies [Abstract] |
Use of Estimates | Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and disclosures of contingencies at the date of the unaudited condensed consolidated financial statements and the reported amounts of net sales and expenses during the reporting period. Such estimates relate to useful lives of fixed and intangible assets, provisions for expected credit losses and customer returns and sales allowances. Such estimates also relate to accrued liabilities, the valuation of stock-based awards, deferred tax valuation allowances, the net realizable value of inventory, and other reserves. On an ongoing basis, management evaluates its estimates. Actual results could differ from those estimates, and such differences may be material to the unaudited condensed consolidated financial statements.
Reclassifications | Reclassifications Certain reclassifications have been made to prior-period amounts to conform to current-period reporting classifications.
Concentrations of Credit Risk | Concentrations of Credit Risk As of June 30, 2023, one customer accounted for 14.8% of the Company’s outstanding trade accounts receivable, net. As of March 31, 2023, Sanken Electric Co., Ltd. (“Sanken”) and another customer accounted for 10.6% and 17.3%, respectively, of the Company’s outstanding trade accounts receivable, net, including related party trade accounts receivable. No other customers accounted for 10% or more of outstanding trade accounts receivable, net as of such dates. For the three months ended June 30, 2023, one customer accounted for 12.2% of total net sales. For the three months ended June 24, 2022, Sanken accounted for 19.2% of total net sales. No other customers accounted for 10% or more of total net sales for either of the three months ended June 30, 2023 or June 24, 2022.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In December 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-06, Reference Rate Reform (Topic 848), Deferral of the Sunset Date of Topic 848. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provided temporary relief when transitioning from the London Interbank Offered Rate (“LIBOR”) to the Secured Overnight Financing Rate (“SOFR”) or another applicable rate during the original transition period ending on December 31, 2022. In March 2021, the UK Financial Conduct Authority announced that the intended cessation date of the overnight 1-, 3-, 6-, and 12-month tenors of U.S. dollar LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848. In light of this development, the FASB issued this update to defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. The adoption of this new guidance did not have a material impact on the Company’s financial position, results of operations, cash flows, or related disclosures.
