Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies 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 Certain reclassifications have been made to prior-period amounts to conform to current-period reporting classifications. Concentrations of Credit Risk As of December 29, 2023, two customers accounted for 24.3% of the Company’s outstanding trade accounts receivable, net. No other customers accounted for 10% or more of outstanding trade accounts receivable, net as of such dates. 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. For the nine-month period ended December 29, 2023, one customer accounted for 11.0% of total net sales. For the three- and nine-month periods ended December 23, 2022, Sanken accounted for 18.1% and 18.7% of total net sales, respectively. No other customers accounted for 10% or more of total net sales for either of the three- or nine-month periods ended December 23, 2022 or for the three-month period ended December 29, 2023. Recent Accounting Pronouncements In December 2023, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures. ASU 2023-09 requires entities to provide additional information of the Company’s tax rate reconciliation, as well as additional disclosures about income taxes paid by jurisdictions. ASU 2023-09 is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted. The ASU 2023-09 should be applied prospectively, but entities have the option to apply it retrospectively for each period presented. The Company is currently evaluating the impact of adopting this guidance. In December 2022, the FASB issued 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 was 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. All other recent accounting pronouncements were determined to not have a material impact on the Company’s financial position, results of operations, cash flows, or related disclosures.
