THE COMPANY

THE COMPANY | |
THE COMPANY | 1. THE COMPANY: Power Integrations, Inc. (“Power Integrations” or the “Company”), incorporated in California on March 25, 1988, and reincorporated in Delaware in December 1997, designs, develops, manufactures and markets analog and mixed-signal integrated circuits (“ICs”) and other electronic components and circuitry used in high-voltage power conversion. The Company’s products are used in power converters that convert electricity from a high-voltage source to the type of power required for a specified downstream use. In most cases, this conversion entails, among other functions, converting alternating current (“AC”) to direct current (“DC”) or vice versa, reducing or increasing the voltage, and regulating the output voltage and/or current according to the customer’s specifications. A large percentage of the Company’s products are ICs used in AC-DC power supplies, which convert the high-voltage AC from a wall outlet to the low-voltage DC required by most electronic devices. Power supplies incorporating the Company’s products are used with all manner of electronic products including mobile phones, computing and networking equipment, appliances, electronic utility meters, battery-powered tools, industrial controls, and “home-automation,” or “internet of things” applications such as networked thermostats, power strips and other building-automation and security devices. The Company also supplies high-voltage LED drivers, which are AC-DC ICs specifically designed for lighting applications that utilize light-emitting diodes, and motor-drivers ICs for brushless DC (“BLDC”) motors used in consumer appliances, HVAC systems, ceiling fans and a variety of industrial applications. The Company also offers high-voltage gate drivers—either standalone ICs or circuit boards containing ICs, electrical isolation components and other circuitry—used to operate high-voltage switches such as insulated-gate bipolar transistors (“IGBTs”) and silicon-carbide (“SiC”) MOSFETs. These combinations of switches and drivers are used for power conversion in high-power applications (i.e., power levels ranging from approximately 100 kilowatts up to gigawatts) such as industrial motors, solar- and wind-power systems, electric vehicles and high-voltage DC transmission systems. |

SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS | |
SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS | 2. SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS: Significant Accounting Policies and Estimates Segment Reporting The Company is organized and operates as one reportable segment, the design, development, manufacture and marketing of integrated circuits and related components for use primarily in the high-voltage power conversion markets. The Company’s chief operating decision maker, the Chief Executive Officer, reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of all intercompany transactions and balances. Estimates The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, allowances for receivables, inventories, litigation and income taxes. These estimates are based on historical facts and various other factors, which the Company believes to be reasonable at the time the estimates are made. However, as the effects of future events cannot be determined with precision, actual results could differ significantly from management’s estimates. Revenue Recognition The Company applies the provisions of Accounting Standards Codification (“ASC”) 606-10, Revenue from Contracts with Customers (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied. Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply manufacturers and distributors. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. In situations where sales are to a distributor, the Company has concluded that its contracts are with the distributor as the Company holds a contract bearing enforceable rights and obligations only with the distributor. As part of its consideration of the contract, the Company evaluates certain factors including the customer’s ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. In determining the transaction price the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company allocates the transaction price to each distinct product based on their relative standalone selling price. The product price as specified on the purchase order is considered the standalone selling price as it is an observable input which depicts the price as if sold to a similar customer in similar circumstances. Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, the Company considers if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer. Frequently, the Company receives orders for products to be delivered over multiple dates that may extend across several reporting periods. The Company invoices for each delivery upon shipment and recognizes revenues for each distinct product delivered, assuming transfer of control has occurred. As scheduled delivery dates are within one year, under the optional exemption provided by ASC 606-10-50-14 revenues allocated to future shipments of partially completed contracts are not disclosed. The Company has also elected the practical expedient under ASC 340-40-25-4 to expense commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized is less than one year. Sales to international customers that are shipped from the Company’s facility outside of the United States are pursuant to EX Works, or EXW, shipping terms, meaning that control of the product transfers to the customer upon shipment from the Company’s foreign warehouse. Sales to international customers that are shipped from the Company’s facility in California are pursuant to Delivered at Frontier, or DAF, shipping terms. As such, control of the product passes to the customer when the shipment reaches the destination country and revenue is recognized upon the arrival of the product in that country. Shipments to customers in the Americas are pursuant to Free on Board, or FOB, point of origin shipping terms meaning that control is passed to the customer upon shipment. Sales to most distributors are made under terms allowing certain price adjustments and limited rights of return (known as “stock rotation”) of the Company’s products held in their inventory or upon sale to their end customers. Revenue from sales to distributors is recognized upon the transfer of control to the distributor. Frequently, distributors need to sell at a price lower than the standard distribution price in order to win business. At the time the distributor invoices its customer or soon thereafter, the distributor submits a “ship-and-debit” price adjustment claim to the Company to adjust the distributor’s cost from the standard price to the pre-approved lower price. After the Company verifies that the claim was pre-approved, a credit memo is issued to the distributor for the ship-and-debit claim. In determining the transaction price, the Company considers ship-and-debit price adjustments to be variable consideration. Such price adjustments are estimated using the expected value method based on an analysis of actual ship-and-debit claims, at the distributor and product level, over a period of time considered adequate to account for current pricing and business trends. Historically, actual price adjustments for ship-and-debit claims have not materially differed from those estimated and included when determining the transaction price. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory. Stock rotation adjustments are an additional form of variable consideration and are also estimated using the expected value method based on historical return rates. Historically, distributor stock rotation adjustments have not been material. Sales to certain distributors are made under terms that do not include rights of return or price concessions after the product is shipped to the distributor. Accordingly, upon application of steps one through five above, product revenue is recognized upon shipment and transfer of control. The Company generally provides an assurance warranty that its products will substantially conform to the published specifications for twelve months from the date of shipment. The Company’s liability is limited to either a credit equal to the purchase price or replacement of the defective part. Returns under warranty have historically been immaterial. As such, the Company does not record a specific warranty reserve or consider activities related to such warranty, if any, to be a separate performance obligation. Inventories Inventories (which consist of costs associated with the purchases of wafers from domestic and offshore foundries and of packaged components from offshore assembly manufacturers, as well as internal labor and overhead associated with the testing of both wafers and packaged components). Inventory is recorded at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of net realizable value. The Company routinely evaluates quantities and values of inventories and records a provision for excess and obsolete inventories to reduce its recorded inventory balance to its estimated net realizable value. In order to determine the provision management considers historical usage, forecasted demand, current economic trends and historical write-offs. Income Taxes Income-tax expense is an estimate of current income taxes payable or refundable in the current fiscal year based on reported income before income taxes. Deferred income taxes reflect the effect of temporary differences and carry-forwards that are recognized for financial reporting and income tax purposes. The Company accounts for income taxes under the provisions of ASC 740, Income Taxe The U.S. tax rules require U.S. tax on foreign earnings, known as global intangible low taxed income. Under U.S. GAAP, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). We selected the deferred method of accounting and recorded the associated basis differences anticipated to influence prospective income inclusion calculations. Goodwill and Intangible Assets Goodwill and the Company’s domain name are evaluated in accordance with ASC 350-10, Goodwill and Other Intangible Assets, In accordance with ASC 360-10, Accounting for the Impairment or Disposal of Long-Lived Assets Cash and Cash Equivalents The Company considers cash invested in highly liquid financial instruments with maturities of three months or less at the date of purchase to be cash equivalents. Marketable Securities The Company generally holds securities until maturity; however, they may be sold under certain circumstances including, but not limited to, when necessary for the funding of acquisitions and other strategic investments. As a result, the Company classifies its investment portfolio as available-for-sale. The Company classifies all investments with a maturity date greater than three months at the date of purchase as short-term marketable securities in its consolidated balance sheet. As of December 31, 2023 and 2022, the Company’s marketable securities consisted primarily of commercial paper, corporate bonds, government securities and/or other high-quality commercial securities. Employee Benefits Plan The Company sponsors a 401(k) tax-deferred savings plan for all employees in the United States who meet certain eligibility requirements. Participants may contribute up to the amount allowable as a deduction for federal income tax purposes. The Company is not required to contribute; however, the Company contributes a certain percentage of employee annual salaries on a discretionary basis, not to exceed an established threshold. The Company provided for a contribution of approximately $2.1 million, $2.0 million and $1.9 million in 2023, 2022 and 2021, respectively. Retirement Benefit Obligations (Pension) The Company recognizes the over-funded or under-funded status of a defined benefit pension or post-retirement plan as an asset or liability in the accompanying consolidated balance sheets. Actuarial gains and losses are recorded in accumulated other comprehensive loss, a component of stockholders’ equity, and are amortized as a component of net periodic cost over the remaining estimated service period of participants. Foreign Currency Risk and Foreign Currency Translation As of December 31, 2023, the Company’s primary transactional currency was U.S. dollars; in addition, the Company holds cash in Swiss francs and euros to fund the operations of the Company’s Swiss subsidiary. The foreign exchange rate fluctuation between the U.S. dollar versus the Swiss franc and euro is recorded in other income in the consolidated statements of income. Gains and losses arising from the remeasurement of non-functional currency balances are recorded in other income in the accompanying consolidated statements of income. The Company recognized a loss of $0.4 million in 2023, an immaterial foreign exchange loss in 2022 and a loss of $0.6 million in 2021. The functional currencies of the Company’s other subsidiaries are the local currencies. Accordingly, all assets and liabilities are translated into U.S. dollars at the current exchange rates as of the applicable balance sheet date. Revenues and expenses are translated at the average exchange rate prevailing during the period. Cumulative gains and losses from the translation of the foreign subsidiaries’ financial statements have been included accumulated other comprehensive loss in stockholders’ equity. Warranty The Company generally warrants that its products will substantially conform to the published specifications for 12 months Advertising Advertising costs are expensed as incurred and amounted to $1.3 million, $1.4 million and $1.3 million in 2023, 2022 and 2021, respectively. Research and Development Research and development costs are expensed as incurred. Indemnifications The Company sells products to its distributors under contracts, collectively referred to as Distributor Sales Agreements (“DSA”). Each DSA contains the relevant terms of the contractual arrangement with the distributor, and generally includes certain provisions for indemnifying the distributor against losses, expenses, and liabilities from damages that may be awarded against the distributor in the event the Company’s products are found to infringe upon a patent, copyright, trademark, or other proprietary right of a third party (Customer Indemnification). The DSA generally limits the scope of and remedies for the Customer Indemnification obligations in a variety of industry-standard respects, including, but not limited to, limitations based on time and geography, and a right to replace an infringing product. The Company also, from time to time, has granted a specific indemnification right to individual customers. The Company believes its internal development processes and other policies and practices limit its exposure related to such indemnifications. In addition, the Company requires its employees to sign a proprietary information and inventions agreement, which assigns the rights to its employees’ development work to the Company. To date, the Company has not had to reimburse any of its distributors or customers for any losses related to these indemnifications and no material claims were outstanding as of December 31, 2023. For several reasons, including the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases, the Company cannot determine the maximum amount of potential future payments, if any, related to such indemnifications. Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements and expand public entities’ segment disclosures in the annual and interim financial statements. The amendment will require disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and within each reported measure of segment profit or loss, an amount and description of its composition for other segment items and interim disclosures of a reportable segment’s profit or loss and assets. The Company is required to adopt the amendments in fiscal year 2024 for annual and retrospective reporting periods and in the first quarter of fiscal year 2025 for all interim and retrospective reporting periods; with early adoption permitted. The Company is currently evaluating the effect of adopting these amendments on its consolidated financial statements. The Company does not expect the amendment to have a material impact on its consolidated financial statements upon adoption. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the potential impact of adopting this new guidance on its consolidated financial statements. |

The number of shares that are released at the end of the performance year can range from zero to 200% of the target number depending on the Company’s performance. The performance metrics of this program are annual targets consisting of a combination of net revenue, non-GAAP operating earnings and strategic goals. As the net revenue, non-GAAP operating income and strategic goals are considered performance conditions, expense associated with these awards, net of estimated forfeitures, is recognized over the service period based on an assessment of the achievement of the performance targets. The fair value of these PSUs is determined using the fair value of the Company’s common stock on the date of the grant, reduced by the discounted present value of dividends expected to be declared before the awards vest. If the performance conditions are not achieved, no compensation cost is recognized and any previously recognized compensation is reversed. A summary of PSU awards outstanding as of December 31, 2023, and activity during the three years then ended, is presented below: Weighted- Average Weighted-Average Remaining Aggregate Shares Grant Date Fair Contractual Term Intrinsic Value (In thousands) Value Per Share (In years) (In thousands) Outstanding at January 1, 2021 150 $ 46.27 Granted 105 $ 84.48 Vested (150) $ 46.27 Forfeited or canceled (1) $ 85.01 Outstanding at December 31, 2021 104 $ 84.47 Granted 119 $ 79.91 Vested (104) $ 84.48 Forfeited or canceled (85) $ 79.89 Outstanding at December 31, 2022 34 $ 79.94 Granted 131 $ 82.96 Vested (34) $ 79.94 Forfeited or canceled (93) $ 82.96 Outstanding at December 31, 2023 38 $ 82.95 — $ 3,131 Outstanding and expected to vest at December 31, 2023 38 — $ 3,131 In February 2023, it was determined that approximately 34,000 shares subject to the PSUs granted in 2022 vested in aggregate; the shares were released to the Company’s employees and executives in the first quarter of 2023. The grant-date fair value of PSU awards released, which were fully vested, in the years ended December 31, 2023, 2022 and 2021, was approximately $2.7 million, $8.8 million and $6.9 million, respectively. PRSU Awards (Long-term Performance Based) The Company’s PRSU program provides for the issuance of PRSUs which will vest based on the Company’s performance measured against the PRSU program’s established performance targets. PRSUs are granted in an amount equal to twice the target number of shares to be issued if the maximum performance metrics are met. The actual number of shares the recipient receives is determined at the end of a three-year performance period based on results achieved versus the Company’s performance goals, and may range from zero to 200% of the target number. The performance goals for PRSUs granted in fiscal 2021, 2022 and 2023 were based on the Company’s compound annual growth rate (“CAGR”) of revenue as measured against the revenue CAGR of the analog semiconductor industry (“Relative Measure”), in each case over the respective three-year performance period. In addition, the PRSUs granted in 2023 (“2023 PRSUs”) also include a performance goal related to the Company’s revenue growth over the respective three-year performance period as compared to defined targets (“Absolute Measure”) with the actual vesting of the 2023 PRSUs calculated based on higher achievement under the Relative Measure or the Absolute Measure. Expense associated with these awards, net of estimated forfeitures, is recorded throughout the year based on an assessment of the expected achievement of the performance targets. If the performance conditions are not achieved, no compensation cost is recognized and any previously recognized compensation is reversed.

The fair value of RSUs is determined using the fair value of the Company’s common stock on the date of the grant, reduced by the discounted present value of dividends expected to be declared before the awards vest. Compensation expense is recognized on a straight-line basis over the requisite service period of each grant adjusted for estimated forfeitures. A summary of RSU awards outstanding as of December 31, 2023, and activity during the three years then ended, is presented below: Weighted-Average Aggregate Weighted-Average Remaining Intrinsic Shares Grant Date Fair Contractual Term Value (In thousands) Value Per Share (In years) (In thousands) Outstanding at January 1, 2021 1,518 $ 35.51 Granted 271 $ 83.79 Vested (546) $ 35.03 Forfeited (99) $ 39.85 Outstanding at December 31, 2021 1,144 $ 46.81 Granted 519 $ 76.01 Vested (481) $ 44.70 Forfeited (86) $ 60.02 Outstanding at December 31, 2022 1,096 $ 60.52 Granted 335 $ 80.97 Vested (418) $ 53.08 Forfeited (32) $ 73.29 Outstanding at December 31, 2023 981 $ 70.27 1.48 $ 80,585 Outstanding and expected to vest at December 31, 2023 918 1.39 $ 75,384 The grant-date fair value of RSUs vested in the years ended December 31, 2023, 2022 and 2021, was approximately $22.2 million, $21.5 million and $19.1 million, respectively. |

SIGNIFICANT CUSTOMERS AND GEOGRAPHIC NET REVENUES | 8. SIGNIFICANT CUSTOMERS AND GEOGRAPHIC NET REVENUES: Customer Concentration The Company’s top ten customers accounted for approximately 80%, 76% and 78% of revenues in 2023, 2022 and 2021, respectively. A significant portion of these revenues are attributable to sales of the Company’s products to distributors of electronic components. These distributors sell the Company’s products to a broad, diverse range of end users, including OEMs and merchant power supply manufacturers. Sales to distributors in 2023, 2022 and 2021 were $307.4 million, $457.7 million and $525.7 million, respectively. Direct sales to OEMs and power-supply manufacturers accounted for the remainder.

No other customers accounted for 10% or more of the Company’s net revenues in the periods presented. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consisted principally of cash investments and trade receivables. The Company does not have any off-balance-sheet credit exposure related to its customers. As of December 31, 2023 and 2022, 86% and 87% of accounts receivable were concentrated with the Company’s top ten customers, respectively.

COMMON STOCK REPURCHASES AND CASH DIVIDENDS: Common Stock Repurchases From time to time the Company’s board of directors has authorized the use of funds to repurchase shares of the Company’s common stock. In October 2018, the Company’s board of director’s authorized the use of $80.0 million for the repurchase of the Company’s common stock, and in each of April 2021 and October 2021 In 2023, 2022 and 2021 the Company purchased approximately 0.8 million shares, 3.8 million shares and 0.9 million shares, respectively, for approximately $55.3 million, $311.1 million and $73.9 million, respectively. As of December 31, 2023, the Company had $26.0 million available for future stock repurchases. Authorization of future stock repurchase programs is at the discretion of the Company’s board of directors and will depend on the Company’s financial condition, results of operations, capital requirements and business conditions as well as other factors. Common Stock Dividend The following table presents the quarterly dividends declared per share of the Company’s common stock for the periods indicated: Year Ended December 31, 2023 2022 2021 First Quarter $ 0.19 $ 0.18 $ 0.13 Second Quarter $ 0.19 $ 0.18 $ 0.13 Third Quarter $ 0.19 $ 0.18 $ 0.13 Fourth Quarter $ 0.20 $ 0.18 $ 0.15 The Company paid approximately $44.0 million, $41.5 million and $32.6 million in cash dividends during 2023, 2022 and 2021, respectively. In January 2021, 2022 In January 2022, the Company’s board of directors raised the quarterly cash dividend by an additional $0.03 per share with the declaration of four cash dividends of $0.18 per share (in lieu of the $0.15 per share announced in October 2021) to be paid to stockholders of record at the end of each quarter in 2022.

EARNINGS PER SHARE | |
EARNINGS PER SHARE | 10. EARNINGS PER SHARE: Basic earnings per share are calculated by dividing net income by the weighted-average shares of common stock outstanding during the period. Diluted earnings per share are calculated by dividing net income by the weighted-average shares of common stock and dilutive common equivalent shares outstanding during the period. Dilutive common equivalent shares included in this calculation consist of dilutive shares issuable upon the assumed exercise of outstanding common stock options, the assumed vesting of outstanding restricted stock units, the assumed issuance of awards under the stock purchase plan and contingently issuable performance-based awards, as computed using the treasury stock method. A summary of the earnings per share calculation is as follows: Year Ended December 31, (In thousands, except per share amounts) 2023 2022 2021 Basic earnings per share: Net income $ 55,735 $ 170,851 $ 164,413 Weighted-average common shares 57,195 57,801 60,327 Basic earnings per share $ 0.97 $ 2.96 $ 2.73 Diluted earnings per share: (1) Net income $ 55,735 $ 170,851 $ 164,413 Weighted-average common shares 57,195 57,801 60,327 Effect of dilutive awards: Employee stock plans 427 570 1,140 Diluted weighted-average common shares 57,622 58,371 61,467 Diluted earnings per share $ 0.97 $ 2.93 $ 2.67 (1) The Company includes the shares underlying performance-based awards in the calculation of diluted earnings per share if the performance conditions have been satisfied as of the end of the reporting period and excludes such shares when the necessary conditions have not been met. The Company has included in the 2023, 2022 and 2021 calculations those shares that were contingently issuable upon the satisfaction of the performance conditions as of the end of the respective periods. In the years ended December 31, 2023, 2022 and 2021, no outstanding stock awards were determined to be anti-dilutive and therefore were excluded from the computation of diluted earnings per share. |

In 2023, the rate was further favorably impacted by release of $7.6 million of reserves related to federal uncertain tax positions as the statute of limitations for review of these positions expired. These benefits were partially offset by foreign income subject to U.S. tax, known as global intangible low-taxed income. The Company’s primary jurisdiction where foreign earnings are derived is the Cayman Islands, which is a non-taxing jurisdiction. Income earned in other foreign jurisdictions was not material. The Company has not been granted any incentivized tax rates and does not operate under any tax holidays in any jurisdiction. The components of the net deferred income tax assets (liabilities) were as follows: December 31, (In thousands) 2023 2022 Deferred tax assets: Capitalized R&D costs $ 30,886 $ 20,666 Other reserves and accruals 861 2,516 Tax credit carry-forwards 28,223 26,154 Stock compensation 1,543 1,559 Capital losses 141 150 Net operating loss 2,269 2,217 Other 465 439 Valuation allowance (31,031) (29,036) 33,357 24,665 Deferred tax liabilities: Depreciation (5,040) (5,596) (5,040) (5,596) Net deferred tax assets $ 28,317 $ 19,069 In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities and projected future taxable income. In the event that the Company determines, based on available evidence and management judgment, that all or part of the net deferred tax assets will not be realized in the future, the Company would record a valuation allowance in the period the determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a material impact on its results of operations and financial position. As of December 31, 2023, the Company continues to maintain a valuation allowance primarily as a result of its California, New Jersey and Canada deferred tax assets as the Company believes that it is not more likely than not that the deferred tax assets will be fully realized. As of December 31, 2023, the Company had utilized all of its federal research and development tax credit carryforwards. As of December 31, 2023, the Company had California research and development tax credit carryforwards of approximately $40.7 million (there is no expiration of research and development tax credit carryforwards for the state of California) and California net operating losses of $44.2 million which will begin to expire in 2032 2030 2029 The Tax Act signed into law on December 22, 2017, generally allows companies to repatriate accumulated foreign earnings without incurring additional U.S. federal taxes beginning after December 31, 2017. Local foreign and U.S. states taxes may still be incurred upon repatriation. The Company has not provided for U.S. taxes on its undistributed earnings of foreign subsidiaries. The determination of the future tax consequences of the remittance of these earnings is not practicable. Unrecognized Tax Benefits The Company applies the provisions of ASC 740-10, relating to accounting for uncertain income taxes. Reconciliation of the beginning and ending amount of unrecognized tax benefits: Unrecognized (In thousands) Tax Benefits Unrecognized tax benefits balance at January 1, 2021 $ 21,051 Gross increase for tax positions of current year 2,068 Gross decrease for tax positions of prior years — Statute of limitation release for tax positions of prior years (1,756) Unrecognized tax benefits balance at December 31, 2021 21,363 Gross increase for tax positions of current year 2,188 Gross decrease for tax positions of prior years — Statute of limitation release for tax positions of prior years (165) Unrecognized tax benefits balance at December 31, 2022 23,386 Gross increase for tax positions of current year 605 Gross decrease for tax positions of prior years — Statute of limitation release for tax positions of prior years (7,602) Unrecognized tax benefits balance at December 31, 2023 $ 16,389 The Company’s total unrecognized tax benefits as of December 31, 2023, 2022 and 2021, were $16.4 million, $23.4 million and $21.4 million, respectively. An income tax benefit of $4.5 million, net of valuation allowance adjustments, would be recorded if fiscal year 2023 unrecognized tax benefits are recognized. The Company cannot reasonably estimate the amount of the unrecognized tax benefit that could be adjusted in the next twelve months. The Company’s continuing practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had accrued interest and penalties of $0.3 million and $1.2 million as of December 31, 2023 and 2022, respectively, which have been recorded in long-term income taxes payable in the accompanying consolidated balance sheets. As of December 31, 2023, the Company has concluded all U.S. federal income tax matters for the years through 2019. However, due to tax attributes, the IRS may calculate tax adjustments for the 2017 transition tax calculation for positions taken prior to 2017 since it has an extended statute of limitations period totaling six years. The California Franchise Tax Board has started an audit for the Company’s tax years 2018 and 2019, it is currently ongoing. |

The Company also owns a research and development facility in New Jersey, a design center in Germany and a multipurpose office building in Switzerland. The Company’s leases consist of operating leases for administrative office spaces, research-and-development facilities and sales offices in various countries around the world. The Company determines whether an arrangement is a lease at inception. Some lease agreements contain lease and non-lease components, which are accounted for as a single lease component. Total lease expense was $3.6 million for the year ended December 31, 2023, and $3.3 million in both the years ended December 31, 2022 and 2021; short-term and variable lease expenses were not material during these periods.

Remaining lease terms range from one some of which include options to extend for up to five years, and some of which include options to terminate within one year. Leases with an initial term of twelve months or less are not recorded on the balance sheet. As the Company’s leases do not provide an implicit rate, the present value of future lease payments is determined using the Company’s incremental borrowing rate based on information available at commencement date.

LEGAL PROCEEDINGS AND CONTINGENCIES | |
LEGAL PROCEEDINGS AND CONTINGENCIES | 13. LEGAL PROCEEDINGS AND CONTINGENCIES: From time to time in the ordinary course of business, the Company becomes involved in lawsuits, or customers and distributors may make claims against the Company. In accordance with ASC 450 10, Contingencies, the Company makes a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. On January 6, 2020, the Company filed a complaint against CogniPower LLC in the United States District Court for the District of Delaware for infringement of two of the Company’s patents and seeking a declaration of non-infringement with respect to patents that CogniPower had charged the Company’s customers with infringing, based on customer use of the Company’s products. In response, CogniPower filed a motion to dismiss the Company’s declaratory judgment claims on the basis that CogniPower had not threatened the Company directly with suit. That motion was granted, so CogniPower’s claims for infringement initially went forward separately in their lawsuit against the Company’s customers in the District of Delaware, but the Company filed a motion to intervene in that lawsuit and received a ruling allowing the Company to intervene in CogniPower’s customer lawsuit on February 1, 2021, and the parties thereafter agreed to dismiss the Company’s separate lawsuit against CogniPower. The remaining case is currently stayed, but the Company recently filed a motion to amend its claims against CogniPower to include three additional patents that are in the same family as the two CogniPower patents that are already in the lawsuit, after CogniPower accused the Company’s customers of infringing those three related patents in a lawsuit in the Eastern District of Texas. A ruling on the Company’s motion is expected in the coming months, and the Company believes it has strong claims and defenses with respect to all of CogniPower’s asserted patents and intends to vigorously defend itself against CogniPower’s claims against the Company’s technology, with appeals to follow if necessary. On October 31, 2022, Waverly Licensing LLC filed a complaint against the Company in the United States District Court for the Western District of Texas. In its complaint, Waverly alleged that the Company was infringing one patent pertaining to charging a battery-operated device. The Company believes it has strong claims and defenses, and intends to vigorously defend itself against Waverly’s claims, with appeals to follow if necessary. Because the Company believed that Waverly’s Texas complaint was improperly filed in the wrong court, the Company filed a motion to dismiss, and on November 30, 2022, the Company filed a complaint against Waverly Licensing LLC and related entities IP Edge LLC, Mavexar LLC, and Array IP LLC in the United States District Court for the District of Delaware seeking a declaration of non-infringement with respect to a patent that Waverly charged the Company with infringing. The Texas court thereafter dismissed Waverly’s Texas complaint. The Company’s Delaware lawsuit is in its earliest stages, but on April 6, 2023, the Delaware defendants filed a motion to dismiss based on a series of covenants not to sue that the Delaware defendants filed with the Court, with further proceedings on the Delaware defendants’ motion expected in the coming months. The Company is unable to predict the outcome of legal proceedings with certainty, and there can be no assurance that the Company will prevail in the above-mentioned unsettled litigations. These litigations, whether or not determined in the Company’s favor or settled, will be costly and will divert the efforts and attention of the Company’s management and technical personnel from normal business operations, potentially causing a material adverse effect on the business, financial condition and operating results. Currently, the Company is not able to estimate a loss or a range of loss for the ongoing litigations disclosed above, however adverse determinations in litigation could result in monetary losses, the loss of proprietary rights, subject the Company to significant liabilities, require the Company to seek licenses from third parties or prevent the Company from licensing the technology, any of which could have a material adverse effect on the Company’s business, financial condition and operating results. |

The plan assets, which provide benefits in the event of an employee’s retirement, death or disability, are held in legally autonomous trustee-administered funds that are subject to Swiss law. Benefits are based on the employee’s age, years of service and salary, and the plan is financed by contributions by both the employee and the Company. The net periodic benefit cost of the Pension Plan was not material to the Company’s financial statements during the years ended December 31, 2023, 2022 and 2021. At December 31, 2023, the projected benefit obligation was $11.4 million, the plan assets were $7.9 million and the net pension liability was $3.5 million. As of December 31, 2022, the projected benefit obligation was $12.1 million, the plan assets were $8.2 million, and the net pension liability was $3.9 million.

The Company expects to make contributions to the Pension Plan of approximately $0.4 million during 2024. The accumulated unrealized actuarial activity on pension benefits, net of tax, at December 31, 2023, 2022 and 2021 was $1.6 million gain, $0.9 million gain and $0.7 million loss, respectively.

The Credit Agreement was amended with an effective date of June 28, 2023 to include the Secured Overnight Financing Rates (“SOFR”) as interest rate benchmark rates, with all other terms remaining the same. The Company’s ability to borrow under the revolving line of credit is conditioned upon the Company’s compliance with specified covenants, including reporting and financial covenants, primarily a minimum cash requirement and a debt to earnings ratio. The Credit Agreement terminates on June 7, 2026; all advances under the revolving line of credit will become due on such date, or earlier in the event of a default.

These estimates are based on historical facts and various other factors, which the Company believes to be reasonable at the time the estimates are made. However, as the effects of future events cannot be determined with precision, actual results could differ significantly from management’s estimates. |
Revenue Recognition | Revenue Recognition The Company applies the provisions of Accounting Standards Codification (“ASC”) 606-10, Revenue from Contracts with Customers (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied. Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply manufacturers and distributors. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. In situations where sales are to a distributor, the Company has concluded that its contracts are with the distributor as the Company holds a contract bearing enforceable rights and obligations only with the distributor. As part of its consideration of the contract, the Company evaluates certain factors including the customer’s ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. In determining the transaction price the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company allocates the transaction price to each distinct product based on their relative standalone selling price. The product price as specified on the purchase order is considered the standalone selling price as it is an observable input which depicts the price as if sold to a similar customer in similar circumstances. Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which typically occurs at shipment. Further, in determining whether control has transferred, the Company considers if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer. Frequently, the Company receives orders for products to be delivered over multiple dates that may extend across several reporting periods. The Company invoices for each delivery upon shipment and recognizes revenues for each distinct product delivered, assuming transfer of control has occurred. As scheduled delivery dates are within one year, under the optional exemption provided by ASC 606-10-50-14 revenues allocated to future shipments of partially completed contracts are not disclosed. The Company has also elected the practical expedient under ASC 340-40-25-4 to expense commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized is less than one year. Sales to international customers that are shipped from the Company’s facility outside of the United States are pursuant to EX Works, or EXW, shipping terms, meaning that control of the product transfers to the customer upon shipment from the Company’s foreign warehouse. Sales to international customers that are shipped from the Company’s facility in California are pursuant to Delivered at Frontier, or DAF, shipping terms. As such, control of the product passes to the customer when the shipment reaches the destination country and revenue is recognized upon the arrival of the product in that country. Shipments to customers in the Americas are pursuant to Free on Board, or FOB, point of origin shipping terms meaning that control is passed to the customer upon shipment. Sales to most distributors are made under terms allowing certain price adjustments and limited rights of return (known as “stock rotation”) of the Company’s products held in their inventory or upon sale to their end customers. Revenue from sales to distributors is recognized upon the transfer of control to the distributor. Frequently, distributors need to sell at a price lower than the standard distribution price in order to win business. At the time the distributor invoices its customer or soon thereafter, the distributor submits a “ship-and-debit” price adjustment claim to the Company to adjust the distributor’s cost from the standard price to the pre-approved lower price. After the Company verifies that the claim was pre-approved, a credit memo is issued to the distributor for the ship-and-debit claim. In determining the transaction price, the Company considers ship-and-debit price adjustments to be variable consideration. Such price adjustments are estimated using the expected value method based on an analysis of actual ship-and-debit claims, at the distributor and product level, over a period of time considered adequate to account for current pricing and business trends. Historically, actual price adjustments for ship-and-debit claims have not materially differed from those estimated and included when determining the transaction price. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory. Stock rotation adjustments are an additional form of variable consideration and are also estimated using the expected value method based on historical return rates. Historically, distributor stock rotation adjustments have not been material. Sales to certain distributors are made under terms that do not include rights of return or price concessions after the product is shipped to the distributor. Accordingly, upon application of steps one through five above, product revenue is recognized upon shipment and transfer of control. The Company generally provides an assurance warranty that its products will substantially conform to the published specifications for twelve months from the date of shipment. The Company’s liability is limited to either a credit equal to the purchase price or replacement of the defective part. Returns under warranty have historically been immaterial. As such, the Company does not record a specific warranty reserve or consider activities related to such warranty, if any, to be a separate performance obligation. |
Inventories | Inventories Inventories (which consist of costs associated with the purchases of wafers from domestic and offshore foundries and of packaged components from offshore assembly manufacturers, as well as internal labor and overhead associated with the testing of both wafers and packaged components). Inventory is recorded at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of net realizable value. The Company routinely evaluates quantities and values of inventories and records a provision for excess and obsolete inventories to reduce its recorded inventory balance to its estimated net realizable value. In order to determine the provision management considers historical usage, forecasted demand, current economic trends and historical write-offs. |
Income Taxes | Income Taxes Income-tax expense is an estimate of current income taxes payable or refundable in the current fiscal year based on reported income before income taxes. Deferred income taxes reflect the effect of temporary differences and carry-forwards that are recognized for financial reporting and income tax purposes. The Company accounts for income taxes under the provisions of ASC 740, Income Taxe The U.S. tax rules require U.S. tax on foreign earnings, known as global intangible low taxed income. Under U.S. GAAP, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). We selected the deferred method of accounting and recorded the associated basis differences anticipated to influence prospective income inclusion calculations. |
Goodwill and Intangible Assets | Goodwill and Intangible Assets Goodwill and the Company’s domain name are evaluated in accordance with ASC 350-10, Goodwill and Other Intangible Assets, In accordance with ASC 360-10, Accounting for the Impairment or Disposal of Long-Lived Assets |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers cash invested in highly liquid financial instruments with maturities of three months or less at the date of purchase to be cash equivalents. |
Marketable Securities | Marketable Securities The Company generally holds securities until maturity; however, they may be sold under certain circumstances including, but not limited to, when necessary for the funding of acquisitions and other strategic investments. As a result, the Company classifies its investment portfolio as available-for-sale. The Company classifies all investments with a maturity date greater than three months at the date of purchase as short-term marketable securities in its consolidated balance sheet. As of December 31, 2023 and 2022, the Company’s marketable securities consisted primarily of commercial paper, corporate bonds, government securities and/or other high-quality commercial securities. |
Employee Benefits Plan | Employee Benefits Plan The Company sponsors a 401(k) tax-deferred savings plan for all employees in the United States who meet certain eligibility requirements. Participants may contribute up to the amount allowable as a deduction for federal income tax purposes. The Company is not required to contribute; however, the Company contributes a certain percentage of employee annual salaries on a discretionary basis, not to exceed an established threshold. The Company provided for a contribution of approximately $2.1 million, $2.0 million and $1.9 million in 2023, 2022 and 2021, respectively. |
Retirement Benefit Obligations (Pension) | Retirement Benefit Obligations (Pension) The Company recognizes the over-funded or under-funded status of a defined benefit pension or post-retirement plan as an asset or liability in the accompanying consolidated balance sheets. Actuarial gains and losses are recorded in accumulated other comprehensive loss, a component of stockholders’ equity, and are amortized as a component of net periodic cost over the remaining estimated service period of participants. |
Foreign Currency Risk and Foreign Currency Translation | Foreign Currency Risk and Foreign Currency Translation As of December 31, 2023, the Company’s primary transactional currency was U.S. dollars; in addition, the Company holds cash in Swiss francs and euros to fund the operations of the Company’s Swiss subsidiary. The foreign exchange rate fluctuation between the U.S. dollar versus the Swiss franc and euro is recorded in other income in the consolidated statements of income. Gains and losses arising from the remeasurement of non-functional currency balances are recorded in other income in the accompanying consolidated statements of income. The Company recognized a loss of $0.4 million in 2023, an immaterial foreign exchange loss in 2022 and a loss of $0.6 million in 2021. The functional currencies of the Company’s other subsidiaries are the local currencies. Accordingly, all assets and liabilities are translated into U.S. dollars at the current exchange rates as of the applicable balance sheet date. Revenues and expenses are translated at the average exchange rate prevailing during the period. Cumulative gains and losses from the translation of the foreign subsidiaries’ financial statements have been included accumulated other comprehensive loss in stockholders’ equity. |
Warranty | Warranty The Company generally warrants that its products will substantially conform to the published specifications for 12 months |
Advertising | Advertising Advertising costs are expensed as incurred and amounted to $1.3 million, $1.4 million and $1.3 million in 2023, 2022 and 2021, respectively. |
Research and Development | Research and Development Research and development costs are expensed as incurred. |
Indemnifications | Indemnifications The Company sells products to its distributors under contracts, collectively referred to as Distributor Sales Agreements (“DSA”). Each DSA contains the relevant terms of the contractual arrangement with the distributor, and generally includes certain provisions for indemnifying the distributor against losses, expenses, and liabilities from damages that may be awarded against the distributor in the event the Company’s products are found to infringe upon a patent, copyright, trademark, or other proprietary right of a third party (Customer Indemnification). The DSA generally limits the scope of and remedies for the Customer Indemnification obligations in a variety of industry-standard respects, including, but not limited to, limitations based on time and geography, and a right to replace an infringing product. The Company also, from time to time, has granted a specific indemnification right to individual customers. The Company believes its internal development processes and other policies and practices limit its exposure related to such indemnifications. In addition, the Company requires its employees to sign a proprietary information and inventions agreement, which assigns the rights to its employees’ development work to the Company. To date, the Company has not had to reimburse any of its distributors or customers for any losses related to these indemnifications and no material claims were outstanding as of December 31, 2023. For several reasons, including the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases, the Company cannot determine the maximum amount of potential future payments, if any, related to such indemnifications. |
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements and expand public entities’ segment disclosures in the annual and interim financial statements. The amendment will require disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and within each reported measure of segment profit or loss, an amount and description of its composition for other segment items and interim disclosures of a reportable segment’s profit or loss and assets. The Company is required to adopt the amendments in fiscal year 2024 for annual and retrospective reporting periods and in the first quarter of fiscal year 2025 for all interim and retrospective reporting periods; with early adoption permitted. The Company is currently evaluating the effect of adopting these amendments on its consolidated financial statements. The Company does not expect the amendment to have a material impact on its consolidated financial statements upon adoption. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the potential impact of adopting this new guidance on its consolidated financial statements. |
