Accounting Policies [Abstract] |
Significant Accounting Policies | Significant Accounting Policies Cash and Cash Equivalents The Company considers all highly-liquid investments with an original maturity of 90 days or less and money market mutual funds to be cash equivalents. The Company maintains cash balances and cash equivalents in highly-qualified financial institutions. At various times, such amounts are in excess of insured limits. Cash equivalents can consist of money market mutual funds, government and corporate obligations, and bank time deposits. Investments The Company’s investment policy restricts investments to high credit quality investments with limits on the length to maturity and requires diversification of investment portfolio. These investments, especially corporate obligations, are subject to default risk. The Company classifies its convertible debt investments as available-for-sale ("AFS") securities and reports these investments at fair value with current and long-term AFS investments included in "Other current assets" and "Other assets," respectively, in the Balance Sheets. Unrealized gains or losses, net of tax, are recorded in "Accumulated other comprehensive income (loss)" in the Balance Sheets, and realized gains or losses, as well as current expected credit loss reserves are recorded in "Non-operating income, net" in the Statements of Income. The Company has minority equity investments in privately-held companies that are classified in "Other assets" in the Balance Sheets. Substantially all of these investments are carried at cost because the Company does not have readily determinable fair values or because the Company does not have the ability to exercise significant influence over the companies. The Company has determined that it is not practicable to estimate the fair values of these investments and accounts for them at cost in accordance with ASC 321–Investments. As of January 29, 2023 and January 30, 2022, the Company had aggregate net investments carried at cost of $36.8 million and $31.5 million, respectively. As of January 29, 2023 and January 30, 2022, aggregate net investments accounted for under the equity method of accounting totaled $6.4 million and $6.0 million, respectively. The Company monitors whether there have been any events or changes in circumstances that would have a significant adverse effect on the fair values of these investments and recognizes losses in the Statements of Income when it determines that declines in the fair values of its investments below their cost are other than temporary. The Company recorded investment impairments and credit loss reserves, net of $1.2 million, $1.3 million and $6.8 million during fiscal years 2023, 2022 and 2021, respectively. Accounts Receivable Allowances Accounts receivable are recorded at net realizable value or the amount that the Company expects to collect on gross customer trade receivables. The Company evaluates the collectability of its accounts receivable based on a combination of factors. The Company generally does not require collateral on accounts receivable as the majority of the Company’s customers are large, well-established companies. Historically, bad debt provisions have been consistent with management’s expectations. If the Company becomes aware of a customer’s inability to meet its financial obligations after a sale has occurred, it records an allowance to reduce the net receivable to the amount it reasonably believes it will be able to collect from the customer. For all other customers, the Company recognizes allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment and historical experience. If the financial condition of the Company’s customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future. All of the Company’s accounts receivables are trade-related receivables. Inventories Inventories are stated at lower of cost or net realizable value and consist of materials, labor, and overhead. The Company determines the cost of inventory by the first-in, first-out method. The Company evaluates inventories for excess quantities and obsolescence. This evaluation includes analysis of sales levels by product and projections of future demand. If future demand or market conditions are less favorable than the Company’s projections, a write-down of inventory may be required, and would be reflected in cost of goods sold in the period the revision is made. In order to state the inventory at lower of cost or net realizable value, the Company maintains reserves against inventory to write down its inventory on a part-by-part basis, if required. Business Combinations The Company accounts for business combinations in accordance with ASC 805, “Business Combinations.” The Company allocates the purchase price paid for assets acquired and liabilities assumed in connection with acquisitions based on their estimated fair values at the time of acquisition. This allocation involves a number of assumptions, estimates and judgments that could materially affect the timing or amounts recognized in its financial statements. The most subjective areas include determining the fair values of the following: •intangible assets, including the valuation methodology, estimations of future cash flows, discount rates, market segment growth rates and the Company's assumed market segment share, as well as the estimated useful life of intangible assets; •deferred tax assets and liabilities, uncertain tax positions and tax-related valuation allowances, which are initially estimated as of the acquisition date; •inventory; property, plant and equipment; pre-existing liabilities or legal claims; deferred revenue; and contingent consideration, each as may be applicable; and •goodwill as measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. The Company’s assumptions and estimates are based upon comparable market data and information obtained from management and the management of the acquired companies. The Company allocates goodwill to the reporting units of the business that are expected to benefit from the business combination. Variable Interest Entities The Company consolidates VIEs in accordance with ASC 810, "Consolidation," if it is the primary beneficiary of the VIE, which is determined if it has a controlling financial interest in the VIE. A controlling financial interest will have both of the following characteristics: (i) the power to direct the VIE's activities that most significantly impact the VIE's economic performance and (ii) the obligation to absorb the VIE's losses that could potentially be significant to the VIE or the right to receive the VIE's benefits that could potentially be significant to the VIE. The Company’s variable interests in VIEs may be in the form of equity ownership, contracts to purchase assets, management services, and development agreements between the Company and a VIE, loans provided by the Company to a VIE or other member, and/or guarantees provided by members to banks and other parties. The Company analyzes its investments or other interests to determine whether it represents a variable interest in a VIE. If so, the Company evaluates the facts to determine whether it is the primary beneficiary, based on if it has a controlling financial interest in the VIE. The Company concluded that some of its equity interests represent a variable interest, but it is not the primary beneficiary as prescribed in ASC 810. Specifically, in reaching this conclusion, the Company considered the activities that most significantly drive profitability for these private entities and determined that the activities that most significantly drive profitability are related to the technology and related product road maps. In some cases, the Company has a board observer role, however, it concluded that in these cases it was not in a position of decision-making or other authority to influence the activities of the private entities that could be considered significant with respect to their operations, including research and development plans and changes to their product road maps. Derivatives and Hedging Activities The Company records all derivatives on the Balance Sheets at fair value in accordance with ASC 815, "Derivatives and Hedging" (other than the Convertible Note Hedge Transactions and the Warrants, which are recorded in additional paid-in capital as described above). The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. The Convertible Note Hedge Transactions and the Warrants meet certain accounting criteria under GAAP, are recorded in additional paid-in capital on the Balance Sheets, and are not accounted for as derivatives that are remeasured each reporting period. In accordance with the FASB’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Property, Plant and Equipment Property, plant and equipment are stated at cost or at fair market value at the time of acquisition. Depreciation is computed over the estimated useful lives of the related asset type or term of the operating lease using the straight-line method for financial statement purposes. Maintenance and repairs are charged to expense as incurred and the costs of additions and betterments that increase the useful lives of the assets are capitalized. Goodwill The Company performs an annual impairment assessment of goodwill at the reporting unit level in the fourth quarter of each fiscal year, or more frequently if indicators of potential impairment exist. The analysis may include both qualitative and quantitative factors to assess the likelihood of an impairment. The reporting unit’s carrying value used in an impairment test represents the assignment of various assets and liabilities, excluding certain corporate assets and liabilities, such as cash, investments and debt. Qualitative factors include industry and market considerations, overall financial performance and other relevant events and factors affecting the reporting unit. Additionally, as part of this assessment, the Company may perform a quantitative analysis to support the qualitative factors above by applying sensitivities to assumptions and inputs used in measuring a reporting unit’s fair value. The Company’s quantitative impairment test considers both the income approach and the market approach to estimate a reporting unit's fair value. Significant estimates include market segment growth rates, assumed market segment share, estimated costs and discount rates based on a reporting unit's weighted average cost of capital. The Company tests the reasonableness of the inputs and outcomes of its discounted cash flow analysis against available market data. As the fair values of all of the Company's reporting units exceeded their carrying values, no impairment of goodwill was recorded during fiscal years 2023, 2022 or 2021. Other Intangibles and Long-lived Assets Finite-lived intangible assets resulting from business acquisitions or technology licenses purchased are amortized on a straight-line basis over their estimated useful lives. The useful lives of acquisition-related intangible assets represent the point where over 90% of realizable undiscounted cash flows for each intangible asset are recognized. The assigned useful lives are based upon the Company’s historical experience with similar technology and other intangible assets owned by the Company. The useful life of technology licenses is usually based on the term of the agreement. Acquired in-process research and development ("IPR&D") projects, which represent projects that had not reached technological feasibility as of the date of acquisition, are recorded at fair value. Initially, these are classified as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts. Upon completion of development, acquired IPR&D asset balances are transferred to finite-lived intangible assets and amortized over their useful lives. The asset balances relating to projects that are abandoned after acquisition are impaired and recorded in "Product development and engineering" ("R&D") expense in the Statements of Income. The Company reviews indefinite-lived intangible assets for impairment on an annual basis in conjunction with goodwill or whenever events or changes in circumstances indicate that the carrying value may exceed its fair value. Impairment of indefinite-lived intangible assets is measured by comparing the carrying amount of the asset to its fair value. The Company assesses finite-lived intangibles and long-lived assets for impairment when indicators of impairment, such as reductions in demand or significant industry and economic slowdowns in the semiconductor industry, are present. Reviews are performed to determine whether the carrying value of an asset is impaired, based on comparisons to undiscounted expected future cash flows. If this comparison indicates that there is impairment, the impaired asset is written down to fair value, which is typically calculated using: (i) quoted market price trends and internal factors such as changes in the Company's business strategy and/or (ii) discounted expected future cash flows utilizing a discount rate. Impairment is based on the excess of the carrying amount over the fair value of those assets the Company forecasts for specific product lines. Also, the Company reassesses the estimated remaining useful lives of any impaired assets and adjusts accordingly estimates of future amortization expense related to these assets. For intangible long-lived assets, which consist of core technology and customer relationships, the Company uses the multi-period excess earnings method (an income approach) or the replacement cost method (a cost approach) to determine fair value. The multi-period excess earnings method estimates the value of the asset based on the present value of the after-tax cash flows attributable to the intangible asset, which includes the Company's estimates of forecasted revenue, operating margins, taxes, and discount rate. The replacement cost method incorporates a market participant’s assumption that an in-use premise is the highest and best use of customer relationships and core technology. The Company estimates the cost it would incur to rebuild or re-establish the intangible asset and the associated effort required to develop it. The fair values of individual tangible long-lived assets are determined using the cost to reproduce the long-lived asset and taking into account the age, condition, inflation using the U.S. Bureau of Labor Statistics and Marshall Valuation Services, and cost to ready the long-lived asset for its intended use. Additionally, the Company considers the potential existence of functional and economic obsolescence and quantifies these elements in its cost approach as appropriate. Functional Currency The Company's reporting currency is the U.S. dollar. The Company determines the functional currency of each of its foreign subsidiaries and their operating divisions based on the primary currency in which they operate. Revenue and expense items denominated in foreign currencies are translated at exchange rates prevailing during the period. When translating from the local currency to the functional currency, monetary assets and liabilities denominated in foreign currencies are translated at the period-end exchange rates, and non-monetary assets and liabilities are translated at exchange rates in effect when the assets are acquired or the obligations are incurred. Foreign exchange gains and losses are reflected in net income for the period. The foreign exchange gains and losses arising from translation from the functional currency to the reporting currency are reported as a component of other comprehensive income. Fair Value Measurements When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. The Company uses the following three levels of inputs in determining the fair value of the Company’s assets and liabilities, focusing on the most observable inputs when available: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities in active markets or other inputs that are observable for the assets or liabilities, either directly or indirectly. Level 3—Unobservable inputs based on the Company’s own assumptions, requiring significant management judgment or estimation. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is disclosed is determined based on the lowest level input that is significant to the fair value measurement. Revenue Recognition The Company derives its revenue primarily from the sale of its products and services into various end markets. Recurring and other services revenue includes sales from cloud services, cellular connectivity services, managed connectivity and application services, software licenses, technical support services, extended warranty services, solution design and consulting services. Revenue is recognized in accordance with ASC 606, "Revenue from Contracts with Customers," when control of products is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for these products. Control is generally transferred when products are shipped and, to a lesser extent, when the products are delivered. Recovery of costs associated with product design and engineering services are recognized during the period in which services are performed and are reported as a reduction to product development and engineering expense. Historically, these recoveries have not exceeded the cost of the related development efforts. Recurring and other services revenue is recognized over time as the service is rendered or at a point in time upon completion of a service. The Company includes revenue related to granted technology licenses as part of "Net sales" in the Statements of Income. Historically, revenue from these arrangements has not been significant though they are part of its recurring ordinary business. The Company determines revenue recognition through the following five steps: •Identification of the contract, or contracts, with a customer; •Identification of the performance obligations in the contract; •Determination of the transaction price; •Allocation of the transaction price to the performance obligations in the contract; and •Recognition of revenue when, or as, performance obligations are satisfied. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. The Company’s revenue contracts generally represent a single performance obligation to sell its products to trade customers. Net sales reflect the transaction prices for contracts, which include units shipped at selling prices reduced by variable consideration. Determination of variable consideration requires judgment by the Company. Variable consideration includes expected sales returns and other price adjustments. Variable consideration is estimated using the expected value method considering all reasonably available information, including the Company’s historical experience and its current expectations, and is reflected in the transaction price when sales are recorded. Sales returns are generally accepted at the Company’s discretion or from distributors with such rights. The Company’s contracts with trade customers do not have significant financing components or non-cash consideration. The Company provides an assurance type warranty, which is typically not sold separately and does not represent a separate performance obligation. Contract Modifications: If a contract is modified, which does not normally occur, changes in contract specifications and requirements must be accounted for. The Company considers contract modifications to exist when the modification creates new, or changes existing, enforceable rights and obligations. Most of the Company’s contract modifications are to distributor agreements for adding new goods or services that are considered distinct from the existing contract and the change in contract price reflects the standalone selling price of the distinct service. Disaggregated Revenue: The Company disaggregates revenue from contracts with customers by types of products and geography, as it believes it best depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. See Note 16, Segment Information, for further information on revenues by product line and geographic region. Contract Balances: Accounts receivable represents the Company’s unconditional right to receive consideration from its customers. Contract assets consist of the Company’s right to consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditioned on something other than the passage of time. ASC 606 also requires an entity to present a revenue contract as a contract liability in instances when a customer pays consideration, or an entity has a right to an amount of consideration that is unconditional (i.e., receivable), before the entity transfers a good or service to the customer. The Company's contract asset and contract liability balances were not material as of January 29, 2023 and January 30, 2022. There were no impairment losses recognized on the Company’s accounts receivable or contract assets during the fiscal year ended January 29, 2023. Contract Costs: All incremental customer contract acquisition costs are expensed as they are incurred as the amortization period of the asset that the Company otherwise would have recognized is one year or less in duration. Significant Financing Component: The Company does not adjust the promised amount of consideration for the effects of a significant financing component as the Company expects, at contract inception, that the period between when the Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less. Sales Tax Exclusion from the Transaction Price: The Company excludes from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from the customer. Shipping and Handling Activities: The Company accounts for shipping and handling activities performed after a customer obtains control of the good as activities to fulfill the promise to transfer the good. Cost of Sales Cost of sales includes materials, depreciation on fixed assets used in the manufacturing process, shipping costs, direct labor and overhead, and amortization of acquired technology intangible assets. Reclassification In fiscal year 2023, the Company reclassified amounts recorded for amortization of acquired technology intangible assets as a component of cost of sales. This was applied retrospectively and resulted in the reclassification of $4.9 million and $7.7 million of amortization of acquired technology intangible assets for fiscal years 2022 and 2021, respectively, from "Intangible amortization" within "Total operating costs and expenses, net" to "Amortization of acquired technology" within "Total cost of sales" in the Statements of Income, which also had the impact of reducing gross profit by the same amounts. This reclassification did not impact the Company's operating income, net income or earnings per share for any historical periods and also did not impact the Company's Balance Sheets or Statements of Cash Flows. Sales and Marketing The Company expenses sales and marketing costs, which include advertising costs, as they are incurred. Advertising costs were $1.5 million, $1.8 million and $1.0 million fo r fiscal years 2023, 2022 and 2021, respectively. Product Development and Engineering Product development and engineering costs are charged to expense as incurred. Recoveries from nonrecurring engineering services are recorded as an offset to product development expense incurred in support of this effort since these activities do not represent an earnings process core to the Company’s business and serve as a mechanism to partially recover development expenditures. The Company received approximately $10.1 million, $7.5 million and $9.6 million of recoveries for nonrecurring engineering services in fiscal years 2023, 2022 and 2021, respectively. Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts and their respective tax bases. Current and long-term prepaid taxes are included in "Prepaid taxes" and "Other assets," respectively, and current and long-term liabilities for uncertain tax positions are included in "Accrued liabilities" and "Other long-term liabilities," respectively, in the Balance Sheets. As part of the process of preparing the Company’s consolidated financial statements, the Company estimates income taxes in each of the jurisdictions in which it operates. This process involves estimating the current tax liability together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities. The Company must assess the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent the Company believes that recovery is not likely, it must establish a valuation allowance. To the extent the Company changes its valuation allowance in a period, the change is generally recorded through the tax provision in the Statements of Income. The Company continually reviews its position on undistributed earnings from its foreign subsidiaries to determine whether those earnings are indefinitely reinvested offshore. Domestic and foreign operating cash flow forecasts are reviewed to determine the sources and uses of cash. Based on these forecasts, the Company determines the need to accrue deferred tax liabilities associated with its undistributed offshore earnings. Other Comprehensive Income (Loss) Other comprehensive income or loss includes unrealized gains or losses on AFS investments, foreign currency and interest rate hedging activities, and changes in defined benefit plans, which are presented in the Statements of Comprehensive Income. The following table summarizes the changes in other comprehensive income (loss) by component:

Share-Based Compensation The Company has various equity award plans ("Plans") that provide for granting share-based awards to employees and non-employee directors of the Company. The Plans provide for the granting of several available forms of stock compensation such as non-qualified stock option awards ("NQSOs"), restricted stock unit awards ("RSUs") and equity awards with certain market conditions. The Company measures compensation cost for all share-based payments at fair value on the measurement date, which is typically the grant date. RSUs are valued based on the stock price on the measurement date, while NQSOs are valued using the Black-Scholes pricing model, which considers, among other things, estimates and assumptions on the expected life of options, stock price volatility and market value of the Company's common stock. Additionally, for awards with a market condition, the Company uses a Monte Carlo simulation model to estimate grant date fair value, which takes into consideration the range of possible stock price or total stockholder return outcomes. In accordance with ASC 718, "Compensation—Stock Compensation," the Company recognizes forfeitures as they occur. Earnings per Share The computation of basic and diluted earnings per share was as follows:
|  | Fiscal Year Ended
(in thousands, except per share data) |  | January 29, 2023 |  | January 30, 2022 |  | January 31, 2021
Net income attributable to common stockholders |  | $ | 61,380 |  |  | $ | 125,664 |  |  | $ | 59,903 |
Weighted-average shares outstanding–basic |  | 63,770 |  | 64,662 |  | 65,208
Dilutive effect of share-based compensation |  | 243 |  |  | 903 |  | 851 |
Weighted-average shares outstanding–diluted |  | 64,013 |  | 65,565 |  | 66,059
Earnings per share: |  |  |  |  |  |
Basic |  | $ | 0.96 |  |  | $ | 1.94 |  |  | $ | 0.92 |
Diluted |  | $ | 0.96 |  |  | $ | 1.92 |  |  | $ | 0.91 |
Anti-dilutive shares not included in the above calculations: |  |  |  |  |  |
Share-based compensation |  | 1,211 |  |  | 35 |  |  | 406 |
Warrants |  | 8,573 |  |  | — |  |  | — |
Total anti-dilutive shares |  | 9,784 |  | 35 |  | 406
Basic earnings per share is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding during the reporting period. Diluted earnings per share incorporates the incremental shares issuable, calculated using the treasury stock method, upon the assumed exercise of NQSOs and the vesting of RSUs and market-condition RSU awards if certain conditions have been met, but excludes such incremental shares that would have an anti-dilutive effect. Any dilutive effect of the Warrants (see Note 10, Long-Term Debt) is calculated using the treasury-stock method. During the fiscal year ended January 29, 2023, the Warrants were excluded from diluted shares outstanding because the exercise price exceeded the average market price of the Company's common stock for the reporting period. Contingencies From time to time, the Company is a defendant or plaintiff in various legal actions that arise in the normal course of business. The Company is also subject to income tax, indirect tax or other tax claims by tax agencies in jurisdictions in which it conducts business. In addition, the Company is a party to environmental matters including local, regional, state, and federal government clean-up activities at or near locations where the Company currently or has in the past conducted business. The Company is required to assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of reasonably possible losses. A determination of the amount of reserves required for these commitments and contingencies that would be charged to earnings, if any, includes assessing the probability of adverse outcomes and estimating the amount of potential losses. The required reserves, if any, may change due to new developments in each matter or changes in circumstances such as a change in settlement strategy. From time to time, the Company may record contingent earn-out liabilities, which represent the Company’s requirement to make additional payments related to acquisitions based on certain performance targets achieved during the earn-out periods. The Company measures contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The significant unobservable inputs used in the fair value measurements are revenue projections over the earn-out period (or other specified performance targets) and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Recently Adopted Accounting Guidance In August 2020, the FASB issued Accounting Standards Update ("ASU") No. 2020-06 ("ASU 2020-06"), which amends the accounting standards for convertible debt instruments that may be settled entirely or partially in cash upon conversion. ASU 2020-06 eliminates requirements to separately account for liability and equity components of such convertible debt instruments and eliminates the ability to use the treasury stock method for calculating diluted earnings per share for convertible instruments whose principal amount may be settled using shares. Instead, ASU 2020-06 requires (i) the entire amount of the security to be presented as a liability on the balance sheet and (ii) application of the "if-converted" method for calculating diluted earnings per share. Under the "if-converted" method, diluted earnings per share will generally be calculated assuming that all of the notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be anti-dilutive. However, if the principal amount of the convertible debt security being converted is required to be paid in cash and only the excess is permitted to be settled in shares, the if-converted method will produce a similar result as the "treasury stock" method prior to the adoption of ASU 2020-06 for such convertible debt security. The amendments are effective for the Company's annual and interim reporting periods beginning after December 15, 2021, with early adoption permitted for reporting periods beginning after December 15, 2020. The guidance can be applied on a full retrospective basis to all periods presented or a modified retrospective basis with a cumulative effect adjustment to the opening balance of retained earnings during the period of adoption. The Company adopted ASU 2020-06 as of January 31, 2022 and recorded the issuance of its 1.625% Convertible Senior Notes due 2027 (the "Notes") at their face value net of issuance costs in "Other long-term liabilities" and the value of the associated Convertible Note Hedge Transactions and Warrants in "Additional paid-in capital" in the Balance Sheets. The Company did not bifurcate the liability and equity components of the Notes in its Balance Sheets, and uses the if-converted method of calculating diluted earnings per share. Because the principal amount of the Notes upon conversion is required to be paid in cash, and only the excess is permitted to be settled in shares, the application of the if-converted method will produce a similar result as the treasury stock method prior to the adoption of ASU 2020-06. The effect of the treasury stock method is that the shares issuable upon conversion of the Notes are not included in the calculation of diluted earnings per share except to the extent that the conversion value of the Notes exceeds their principal amount. There were no changes to the Company’s previously issued financial statements as the Company had no existing convertible notes prior to issuance of the Notes. See Note 10, Long-Term Debt, for further discussion of the Notes. 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 improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistencies related to recognition of an acquired contract liability, and to payment terms and their effect on subsequent revenue recognized by the acquirer. Among other changes, this ASU requires that an acquirer account for acquired revenue contracts in accordance with ASC 606, "Revenue from Contracts with Customers," as if it had originated the contracts. If the acquirer is unable to assess or rely on how the acquiree applied ASC 606, the acquirer should consider the terms of the acquired contracts as of the contract inception or contract modification date in applying ASC 606 to determine what should be recorded at the acquisition date. The amendments also provide certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The guidance is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company adopted ASU 2021-08 as of October 31, 2022 and applied its provisions in the Company's acquisition of Sierra Wireless, Inc. as disclosed in Note 3, Acquisition and Divestiture. In December 2022, the FASB issued ASU No. 2022-06, "Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848," which affects entities with contracts or hedging relationships that reference an interest rate expected to be discontinued, such as LIBOR. The guidance defers the date through which entities are able to apply optional expedients that permit the entity to not apply otherwise applicable guidance to contracts or transactions that are modified or otherwise affected by reference rate reform from December 31, 2022 to December 31, 2024. The pronouncement is effective immediately for all entities and is applied prospectively. The adoption of this guidance did not have a significant impact on the Company's financial statements or results of operations.
