Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Mar. 25, 2023
Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation We prepare financial statements on a 52- or 53-week year that ends on the last Saturday in March. Fiscal years 2023, 2022, and 2021 were 52-week years. The next 53-week year will be fiscal year 2024.
Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
Reclassifications | Reclassifications Certain reclassifications have been made to prior year balances in order to conform to the current year’s presentation of financial information.
Use of Estimates | Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires the use of management estimates. These estimates are subjective in nature and involve judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at fiscal year-end and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist primarily of money market funds, commercial paper, and U.S. Government Treasury and Agency instruments with original maturities of three months or less at the date of purchase.
Business Combinations | Business Combinations We account for business combinations using the acquisition method of accounting and allocate the fair value of acquisition consideration to the assets acquired and liabilities assumed based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of the assets acquired and liabilities assumed is recorded as goodwill. The results of operations of the business acquired is included in our consolidated statements of income beginning on the date of the acquisition.
Leases | Leases We account for leases under ASC 842, Leases. Our leases generally contain fixed rental payments, with additional variable payments linked to actual common area maintenance costs incurred by the landlord. These variable payments are not included within the lease liability and right-of-use ("ROU") asset, but are recognized as an expense when incurred. As our leases typically do not provide an implicit rate, the Company determines the Incremental Borrowing Rate ("IBR") for each lease based on the information available at the commencement date, taking into consideration necessary adjustments for collateral, currency, and lease term. Operating leases in excess of 12 months are recognized on the balance sheet, with future lease payments recognized as a liability, measured at present value, and the ROU asset recognized for the lease term. Lease expense is recognized in the income statement over the lease term.
Inventories | Inventories We use the lower of cost or net realizable value to value our inventories, with cost being determined on a first-in, first-out basis. One of the factors we consistently evaluate in the application of this method is the extent to which products are accepted into the marketplace. By policy, we evaluate market acceptance based on known business factors and conditions by comparing forecasted customer unit demand for our products over a specific future period, or demand horizon, to quantities on hand at the end of each accounting period. On a quarterly and annual basis, we analyze inventories on a part-by-part basis. Product life cycles and the competitive nature of the industry are factors considered in the evaluation of customer unit demand at the end of each quarterly accounting period. Inventory on-hand in excess of forecasted demand is considered to have reduced market value and, therefore, the cost basis is adjusted to the lower of cost or net realizable value. Typically, market values for excess or obsolete inventories are considered to be zero. Inventory charges recorded for excess and obsolete inventory, including scrapped inventory, were $9.9 million and $6.5 million, in fiscal year 2023 and 2022, respectively. Inventory charges in fiscal year 2023 and 2022 related to a combination of quality issues and inventory exceeding demand.
Property, Plant and Equipment, net | Property, Plant and Equipment, netProperty, plant and equipment is recorded at cost, net of depreciation and amortization. Depreciation and amortization is calculated on a straight-line basis over estimated economic lives, ranging from 3 to 39 years. Leasehold improvements are depreciated over the shorter of the term of the lease or the estimated useful life. Furniture, fixtures, machinery, and equipment are all depreciated over a useful life of 3 to 10 years, while buildings are depreciated over a period of up to 39 years. In general, our capitalized software is amortized over a useful life of 3 years, with capitalized enterprise resource planning software being amortized over a useful life of 10 years. Gains or losses related to retirements or dispositions of fixed assets are recognized in the period incurred. Additionally, if impairment indicators exist, the Company will assess the carrying value in relation to the calculated fair value of the associated asset.
Goodwill | Goodwill Goodwill is recorded at the time of an acquisition and is calculated as the difference between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company tests goodwill for impairment on an annual basis or more frequently if the Company believes indicators of impairment exist. Impairment evaluations involve management’s assessment of qualitative factors to determine whether it is more likely than not that goodwill is impaired. If management concludes from its assessment of qualitative factors that it is more likely than not that impairment exists, then a quantitative impairment test will be performed involving management estimates of future cash flows. Significant management judgment is required in the forecasts of future operating results that are used in these evaluations. Following the quantitative test, an impairment charge would be recorded for the amount the carrying value exceeds the calculated fair value.
Long-Lived Assets | Long-Lived Assets Intangible assets include purchased technology licenses and patents that are reported at cost and are amortized on a straight-line basis over their useful lives, generally ranging from 1 to 5 years. Acquired intangibles include existing technology, core technology or patents, license agreements, in-process research & development, trademarks, tradenames, customer relationships, and non-compete agreements. These assets are amortized on a straight-line basis over lives ranging from 1 to 15 years. We regularly review whether facts or circumstances exist that indicate the carrying values of property, plant and equipment or other long-lived assets, including intangible assets, are impaired. We assess the recoverability of assets by comparing the projected undiscounted net cash flows associated with those assets to their respective carrying amounts. We measure any impairment loss by comparing the fair value of the asset to its carrying amount. We estimate fair value based on discounted future cash flows, quoted market prices, or independent appraisals. During the fourth quarter of fiscal year 2023, the Company recorded $85.8 million of acquired intangible asset impairment charges. See Note 7 — Intangibles, net and Goodwill for further detail. There were no other material intangible asset impairments recorded in fiscal years 2023, 2022, and 2021.
Foreign Currency Translation | Foreign Currency TranslationSome of the Company's subsidiaries utilize the local currency as the functional currency. The Company’s main entities, including the entities that generate the majority of sales and employ the majority of employees, are U.S. dollar functional.
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject us to material concentrations of credit risk consist primarily of cash equivalents, marketable securities, long-term marketable securities, and trade accounts receivable. We are exposed to credit risk to the extent of the amounts recorded on the balance sheet. By policy, our cash equivalents, marketable securities, and long-term marketable securities are subject to certain nationally recognized credit standards, issuer concentrations, sovereign risk, and marketability or liquidity considerations. In evaluating our trade receivables, we perform credit evaluations of our major customers’ financial condition and monitor closely all of our receivables to limit our financial exposure by limiting the length of time and amount of credit extended. In certain situations, we may require payment in advance or utilize letters of credit to reduce credit risk. By policy, we establish a reserve for trade accounts receivable based on the type of business in which a customer is engaged, the length of time a trade account receivable is outstanding, and other knowledge that we may possess relating to the probability that a trade receivable is at risk for non-payment. We had three contract manufacturers aggregated at their parent level, Foxconn, Pegatron and Luxshare Precision, who represented 35 percent, 16 percent, 11 percent, respectively, of our consolidated gross trade accounts receivable as of the end of fiscal year 2023. We had two contract manufacturers aggregated at their parent level, Foxconn and Pegatron, who represented 49 percent and 17 percent, respectively, of our consolidated gross trade accounts receivable as of the end of fiscal year 2022. No other distributor or contract manufacturer had receivable balances that represented more than 10 percent of consolidated gross trade accounts receivable as of the end of fiscal year 2023 or 2022. Since the components we produce are largely proprietary and generally not available from second sources, we consider our end customer to be the entity specifying the use of our component in their design. These end customers may then purchase our products directly from us, from a distributor, or through a third-party manufacturer contracted to produce their end product. For fiscal year 2023, our ten largest end customers represented approximately 92 percent and for each of fiscal years 2022 and 2021, our ten largest end customers represented 93 percent of our sales. For fiscal years 2023, 2022, and 2021, we had one end customer, Apple Inc., who purchased through multiple contract manufacturers and represented approximately 83 percent, 79 percent, and 83 percent, of the Company’s total sales, respectively. No other customer or distributor represented more than 10 percent of net sales in fiscal years 2023, 2022, or 2021.
Revenue Recognition, Shipping Costs | Revenue Recognition We recognize revenue upon the transfer of promised goods or services to customers, in an amount that reflects the consideration the Company expects to be entitled in exchange for those goods or services. Performance Obligations The Company’s single performance obligation is the delivery of promised goods to the customer. The promised goods are explicitly stated in the customer contract and are comprised of a single type of good. This performance obligation is satisfied upon transfer of control of the promised goods to the customer, as defined per the shipping terms within the customer’s contract. The vast majority of the Company’s contracts with customers have an original expected term of one year or less. A s allowed by ASC 606, the Company has not disclosed the value of any unsatisfied performance obligations related to these contracts. Contract balances Payments are typically due within 30 to 60 days of invoicing and terms do not include a significant financing component or noncash consideration. There have been no material impairment losses on accounts receivable. There are no material contract assets or contract liabilities recorded on the consolidated balance sheets. Transaction price The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods to the customer. Fixed pricing is the consideration that is agreed upon in the customer contract. Variable pricing includes rights of return, price protection and stock rotation. Rights of return costs are estimated using the "most likely amount" method by reviewing historical returns to determine the most likely customer return rate and applying materiality thresholds. Price protection includes price adjustments available to certain distributors based upon established book price and a stated adjustment period. Stock rotation is also available to certain distributors based on a stated maximum of prior billings. The Company estimates all variable consideration at the most likely amount which it expects to be entitled. The estimate is based on current and historical information available to the Company, including recent sales activity and pricing. Variable consideration is only included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company defers all variable consideration that does not meet the revenue recognition criteria. Shipping Costs Our shipping and handling costs are included in cost of sales for all periods presented in the consolidated statements of income. Disaggregation of revenue We disaggregate revenue from contracts with customers by product line and ship to location of the customer. Sales are designated in the product line categories of Audio and High-Performance Mixed-Signal ("HPMS"). Total net sales based on the product line disaggregation criteria described above are shown in the table below (in thousands).

Advertising Costs | Advertising CostsAdvertising costs are expensed as incurred.
Stock-Based Compensation | Stock-Based Compensation Stock-based compensation is measured at the grant date based on the grant-date fair value of the awards and is recognized as an expense, on a ratable basis, over the vesting period, which is generally between 1 and 4 years. Determining the amount of stock-based compensation to be recorded requires the Company to develop estimates used in calculating the grant-date fair value of stock options and performance awards (also called market stock units). The Company calculates the grant-date fair value for stock options and market stock units using the Black-Scholes valuation model and the Monte Carlo simulation, respectively. The use of valuation models requires the Company to make estimates of assumptions such as expected volatility, expected term, risk-free interest rate, expected dividend yield, and forfeiture rates. The grant-date fair value of restricted stock units is the market value at grant date multiplied by the number of units.
Income Taxes | Income Taxes We are required to calculate income taxes in each of the jurisdictions in which we operate. This process involves calculating the actual current tax liability as well as assessing temporary differences in the recognition of income or loss for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheet. We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company evaluates the ability to realize its deferred tax assets based on all the facts and circumstances, including projections of future taxable income and expiration dates of carryover tax attributes. The calculation of our tax liabilities involves assessing uncertainties with respect to the application of complex tax rules and the potential for future adjustment of our uncertain tax positions by the U.S. Internal Revenue Service or other taxing jurisdiction. We recognize liabilities for uncertain tax positions based on the required two-step process. The first step requires us to determine if the weight of available evidence indicates that the tax position has met the threshold for recognition; therefore, we must evaluate whether it is more likely than not that the position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step requires us to measure the tax benefit of the tax position taken, or expected to be taken, in an income tax return as the largest amount that is more than 50 percent likely of being realized upon ultimate settlement. We reevaluate the uncertain tax positions each quarter based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, expirations of statutes of limitation, effectively settled issues under audit, and new audit activity. A change in the recognition step or measurement step would result in the recognition of a tax benefit or an additional charge to the tax provision in the period. Although we believe the measurement of our liabilities for uncertain tax positions is reasonable, we cannot assure that the final outcome of these matters will not be different than what is reflected in the historical income tax provisions and accruals. If additional taxes are assessed as a result of an audit or litigation, it could have a material effect on our income tax provision and net income in the period or periods for which that determination is made. We operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues which may require an extended period of time to resolve and could result in additional assessments of income tax. We believe adequate provisions for income taxes have been made for all periods. See Note 19 - Income Taxes for further detail. Government Assistance The Company benefits from the Research and Development Expenditure Credit (“RDEC”) program in the United Kingdom. The RDEC is recorded as an offset to research and development expenses in the consolidated statements of income, $26.2 million and $23.2 million in fiscal years 2023 and 2022, respectively. RDEC receivables are first settled against the Company's United Kingdom income taxes with the remainder paid in cash on an annual basis. RDEC receivables as of March 25, 2023, totaled $47.0 million, presented within "Other current Assets" and "Other assets" on the consolidated balance sheet. While the duration of RDEC benefits is indefinite, the program is subject to future policy changes and RDEC claims are subject to regular audits by the United Kingdom government.
Net Income Per Share | Net Income Per Share Basic net income per share is based on the weighted effect of common shares issued and outstanding and is calculated by dividing net income by the basic weighted average shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares used in the basic net income per share calculation, plus the equivalent number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding. These potentially dilutive items consist primarily of outstanding stock options and restricted stock grants.
Accumulated Other Comprehensive Loss | Accumulated Other Comprehensive Loss Our accumulated other comprehensive loss is comprised of foreign currency translation adjustments and unrealized gains and losses on investments classified as available-for-sale. See Note 18 — Accumulated Other Comprehensive Income (Loss) for additional discussion.
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832) – Disclosures by Business Entities about Government Assistance, which requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution type accounting model. The disclosures requires information about the nature and related policy used for the transactions, the line items on the balance sheet and income statement that are affected and the amounts applicable to each financial statement line item, and significant terms and conditions of the transactions. This ASU is effective for financial statements issued for annual periods beginning after December 15, 2021. The Company adopted this ASU in the fourth quarter of fiscal year 2023 on a prospective basis. See related policy discussion above. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805) – Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured at the acquisition date in accordance with Revenue from Contracts with Customers (Topic 606) as if the acquirer had originated the contracts. Prior to the issuance of this ASU, contract assets and liabilities were recognized at fair value on the acquisition date. This ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within that fiscal year, with early adoption permitted, and should be applied on a prospective basis. The Company early adopted this ASU in the fourth quarter of fiscal year 2023 with no material impact to the financial statements.
Marketable Securities | The Company’s investments have been classified as available-for-sale securities in accordance with U.S. GAAP. Marketable securities are categorized on the consolidated balance sheet as “Marketable securities” within the short-term or long-term classification, as appropriate.
