Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of ON Semiconductor Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of ON Semiconductor Corporation and its subsidiaries (the "Company") as of December 31, 2020 and 2019, and the related consolidated statements of operations and comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2020, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 4 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and

expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Ship and Credit Reserves

As described in Notes 2 and 8 to the consolidated financial statements, the Company’s ship and credit reserves are $180.2 million as of December 31, 2020. Sales returns and allowances, which include ship and credit reserves for distributors, are estimated by management based on historical claims data and expected future claims. Provisions for ship and credit claims are provided for in the same period the related revenue is recognized, and are netted against revenue.

The principal considerations for our determination that performing procedures relating to ship and credit reserves is a critical audit matter are the significant judgment by management in estimating the reserves, which in turn led to significant auditor judgment, subjectivity and effort in performing procedures to evaluate management’s expected future claims assumptions.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the ship and credit reserves. These procedures also included, among others (i) testing management’s process for determining the estimate, (ii) evaluating the appropriateness of the approach used by management in developing the estimate, (iii) evaluating the reasonableness of the expected future claims assumptions, and (iv) testing the completeness and accuracy of historical claims data. Evaluating the assumptions related to the expected future claims involved evaluating whether the assumptions used were reasonable considering the past claim activity.

Valuation of Inventories

As described in Notes 2 and 8 to the consolidated financial statements, the Company’s inventory balance of $1,251.4 million as of December 31, 2020, is stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. Management writes down excess and obsolete inventories based upon a regular analysis of inventory on hand compared to historical and projected end-user demand.

The principal considerations for our determination that performing procedures relating to the valuation of inventories is a critical audit matter are the significant judgment by management in developing the write down for excess and obsolete inventories. This in turn led to significant auditor judgment, subjectivity and effort in performing procedures to evaluate the reasonableness of management’s analysis, including the inputs utilized and the significant assumptions related to projected end-user demand employed within the analysis.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of inventories. These procedures also included, among others (i) testing management’s process for developing the write down for excess and obsolete inventories, (ii) evaluating the appropriateness of the analysis, and (iii) evaluating the reasonableness of the significant assumptions related to projected end-user demand used by management in developing the write down for excess and obsolete inventories. Evaluating the reasonableness of the assumptions related to projected end-user demand involved considering the performance of product sales and whether they were consistent with evidence obtained in other areas of the audit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Background and Basis of Presentation

ON Semiconductor Corporation, together with its wholly and majority-owned subsidiaries (the "Company"), prepares its consolidated financial statements in accordance with GAAP. As of December 31, 2020, the Company was organized into three operating segments, which also represent its three reportable segments: PSG, ASG and ISG. Additional information about the Company's operating and reportable segments is included in Note 3: ''Revenue and Segment Information''.

The Company assessed certain accounting matters that generally require consideration of forecasted financial information in the context of the information reasonably available as of December 31, 2020, and through the filing date of this Form 10-K. The accounting matters assessed included, but were not limited to, the allowance for doubtful accounts, share-based compensation, inventory valuation, carrying value of indefinite-lived intangible assets, other long-lived assets and goodwill, valuation allowance for tax assets, contingencies and revenue recognition. Future assessment of the current expectations, including of the magnitude and duration of the COVID-19 pandemic, as well as other factors, could result in a material adverse impact to the consolidated financial statements in future reporting periods.

Unless otherwise noted, all dollar amounts are in millions, except per share amounts.

Note 2: Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the assets, liabilities, revenue and expenses of all wholly-owned and majority-owned subsidiaries over which the Company exercises control and, when applicable, entities in which the Company has a controlling financial interest or is the primary beneficiary. Investments in affiliates where the Company does not exert a controlling financial interest are not consolidated. All intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenue and expenses during the reporting period. Management evaluates these estimates and judgments on an ongoing basis and bases its estimates on experience, current and expected future conditions, third-party evaluations and various other assumptions that management believes are reasonable under the circumstances. Significant estimates have been used by management in conjunction with the following: (i) future payouts for customer incentives and amounts subject to allowances and returns; (ii) valuation and obsolescence relating to inventories; (iii) variable and share-based compensation; and (iv) measurement of valuation allowances against deferred tax assets, and evaluations of uncertain tax positions. Additionally, during periods where it becomes applicable, significant estimates will be used by management in determining the future cash flows used to assess and test for impairment of indefinite-lived intangible assets, long-lived assets and goodwill and in assumptions used in connection with business combinations. Actual results may differ from the estimates and assumptions used in the consolidated financial statements.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, demand deposits and highly liquid investments with original maturities at the time of purchase of three months or less. The Company maintains amounts on deposit at various financial institutions, which may at times exceed federally insured limits. However, management periodically evaluates the credit-worthiness of those institutions and has not experienced any losses on such deposits.

Inventories

Inventories are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. General market conditions, as well as the Company's design activities, can cause certain of its products to become obsolete. The Company writes down excess and obsolete inventories based upon a regular analysis of inventory on hand compared to historical and projected end-user demand. The determination of projected end-user demand requires the use of estimates and assumptions related to projected unit sales for each product. These write downs can influence results from operations. For example, when demand for a given part falls, all or a portion of the related inventory that is considered to be in

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

excess of anticipated demand is written down, impacting cost of revenue and gross profit. However, the majority of product inventory that has been previously written down is ultimately discarded. Although the Company does sell some products that have previously been written down, such sales have historically been consistently insignificant and the related impact on the Company's gross profit has also been insignificant.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost and are depreciated over estimated useful lives of 30-50 years for buildings and 3-10 years for computers, machinery and equipment using straight-line methods. Expenditures for maintenance and repairs are charged to operations in the period in which the expense is incurred. When assets are retired or otherwise disposed of, the related costs and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized.

The Company evaluates the recoverability of the carrying amount of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying value of an asset group may not be fully recoverable. A potential impairment charge is evaluated when the undiscounted expected cash flows derived from an asset group are less than its carrying amount. Impairment losses, if applicable, are measured as the amount by which the carrying value of an asset group exceeds its fair value and are recognized in operating results. Judgment is used when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of the asset group.

Business Combination Purchase Price Allocation

The allocation of the purchase price of business combinations is based on management estimates and assumptions, which utilize established valuation techniques appropriate for the technology industry. These techniques include the income approach, cost approach or market approach, depending upon which approach is the most appropriate based on the nature and reliability of available data. Management records the acquired assets and liabilities at fair value. If the income approach is used, the fair value determination is predicated upon the value of the future cash flows that an asset is expected to generate over its economic life. The cost approach takes into account the cost to replace (or reproduce) the asset and the effects on the asset's value of physical, functional and/or economic obsolescence that has occurred with respect to the asset. The market approach is used to estimate value from an analysis of actual market transactions or offerings for economically comparable assets available as of the valuation date. Determining the fair value of acquired technology assets is judgmental in nature and requires the use of significant estimates and assumptions, including the discount rate, revenue growth rates, projected gross margins, and estimated research and development and other operating expenses.

Goodwill

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in a business combination. The Company evaluates its goodwill for impairment annually during the fourth quarter and whenever events or changes in circumstances indicate the carrying value of a reporting unit may not be recoverable. The Company’s divisions are one level below the operating segments, constituting individual businesses, at which level the Company’s segment management conducts regular reviews of the operating results. The Company's divisions, either individually or in a combination, constitute reporting units for purposes of allocating and testing goodwill.

The Company's impairment evaluation consists of a qualitative assessment. If this assessment indicates that it is more likely than not the estimated fair value of a reporting unit exceeds its carrying value, goodwill is not considered impaired. Otherwise, the Company performs a quantitative impairment test by comparing the fair value of a reporting unit with its carrying value, including goodwill. If the carrying value of the net assets associated with the reporting unit exceeds the fair value of the reporting unit, goodwill is considered impaired and will be determined as the amount by which the reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The Company can bypass the qualitative assessment for any period and proceed directly to the quantitative impairment test.

Determining the fair value of the Company's reporting units is subjective in nature and involves the use of significant estimates and assumptions, including projected net cash flows, discount rates and long-term growth rates. The Company determines the fair value of its reporting units based on an income approach derived from the present value of estimated future cash flows. The assumptions about estimated cash flows include factors such as future revenue, gross profit, operating expenses and industry trends. The Company considers historical rates and current market conditions when determining the discount and long-term growth rates to use in its analysis. The Company considers other valuation methods, such as the cost approach or market approach, if it is determined that these methods provide a more representative approximation of fair value.

The Company's acquisitions have resulted in intangible assets consisting of values assigned to customer relationships, patents, developed technology, licenses, IPRD and trademarks. IPRD is considered an indefinite-lived intangible asset until the abandonment or completion of the associated research and development efforts. If abandoned, the assets would be impaired. If the activities are completed, a determination is made regarding the useful lives of such assets and methods of amortization.

The Company is required to test its IPRD assets for impairment annually using the guidance for indefinite-lived intangible assets. The Company calculates the fair value of the IPRD asset and records an impairment charge if the carrying amount exceeds fair value. The Company determines the fair value based on an income approach, which is calculated as the present value of the estimated future cash flows of the IPRD asset. The assumptions about estimated cash flows include factors such as future revenue, gross profit, operating expenses and industry trends. The Company can bypass the qualitative assessment for any asset in any period and proceed directly to the quantitative impairment test.

The remaining intangible assets are considered long-lived assets and are stated at cost less accumulated amortization. These intangible assets are amortized over their estimated useful lives and are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of an asset group containing these assets may not be recoverable.

Leases

The Company determines if an arrangement is a lease at its inception. Operating lease arrangements are comprised primarily of real estate and equipment agreements for which the right-of-use ("ROU") assets are included in other assets and the corresponding lease liabilities, depending on their maturity, are included in accrued expenses and other current liabilities or other long-term liabilities in the Consolidated Balance Sheet.

ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The lease term includes options to extend the lease when it is reasonably certain that the option will be exercised. Leases with a term of 12 months or less are not recorded on the Consolidated Balance Sheet.

The Company uses its estimated incremental borrowing rate in determining the present value of lease payments considering the term of the lease, which is derived from information available at the lease commencement date, giving consideration to publicly available data for instruments with similar characteristics. The Company accounts for the lease and non-lease components as a single lease component.

Debt Issuance Costs

Debt issuance costs for line-of-credit agreements, including the Company's Revolving Credit Facility, are capitalized and amortized over the term of the underlying agreements on a straight-line basis. Amortization of these debt issuance costs is included in interest expense while the unamortized balance is included in other assets.

Debt issuance costs for the Company's convertible notes and term debt are recorded as a direct deduction from the carrying amounts of the such debt, consistent with debt discounts, and are amortized over their term using the effective interest method. Amortization of these debt issuance costs is included in interest expense.

Contingencies

The Company is involved in a variety of legal matters, IP matters, environmental, financing and indemnification contingencies that arise in the ordinary course of business. Based on the information available, management evaluates the relevant range and likelihood of potential outcomes and records the appropriate liability when the amount is deemed probable and reasonably estimable.

Treasury Stock

Treasury stock is recorded at cost, inclusive of fees, commissions and other expenses, when outstanding common shares are repurchased by the Company, including when outstanding shares are withheld to satisfy tax withholding obligations in connection with certain shares pursuant to RSUs under the Company's share-based compensation plans. Reissuance of shares

held in treasury stock is accounted for on a first-in, first-out basis.

Revenue Recognition

The Company generates revenue from sales of its semiconductor products to OEMs, electronic manufacturing service providers and distributors. The Company also generates revenue, to a much lesser extent, from product development agreements and manufacturing services provided to customers. The Company recognizes revenue when it satisfies a performance obligation in an amount reflecting the consideration to which it expects to be entitled. For sales agreements, the Company has identified the promise to transfer products, each of which is distinct, as the performance obligation. For product development agreements, the Company has identified the completion of a service defined in the agreement as the performance obligation. The Company applies a five-step approach in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations in the contract; and (5) recognizing revenue when the performance obligation is satisfied.

Sales agreements with customers are renewable periodically and contain terms and conditions with respect to payment, delivery, warranty and supply, but typically do not require minimum purchase commitments. In the absence of a sales agreement, the Company’s standard terms and conditions apply. The Company considers the customer purchase orders, governed by sales agreements or the Company’s standard terms and conditions, to be the contract with the customer. The Company evaluates certain factors including the customer’s ability to pay (or credit risk).

Most of the Company’s OEM customers negotiate pricing terms on an annual basis, distributors generally negotiate pricing terms on a quarterly basis, while the pricing terms for electronic manufacturing service providers are negotiated periodically during the year. Pricing terms on product development agreements are negotiated at the beginning of a project. The Company allocates the transaction price to each distinct product based on its relative stand-alone selling price.

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. The Company’s OEM customers do not have the right to return products, other than pursuant to the provisions of the Company’s standard warranty. Sales to distributors, however, are typically made pursuant to agreements that provide return rights and stock rotation provisions permitting limited levels of product returns. Sales to certain distributors, primarily those with ship and credit rights, can also be subject to price adjustment on certain products. Although payment terms vary, most distributor agreements require payment within 30 days. In addition, the Company offers cash discounts to certain customers for payments received within an agreed upon time, generally ten days after shipment.

The Company recognizes revenue when it satisfies a performance obligation. The Company recognizes revenue from sales agreements upon transferring control of a product to the customer. This typically occurs when products are shipped or delivered, depending on the delivery terms, or when products that are consigned at customer locations are consumed. The Company recognizes revenue from product development agreements over time based on the cost-to-cost method. Sales returns and allowances, which include ship and credit reserves for distributors, are estimated based on historical claims data and expected future claims. Provisions for discounts and rebates to customers, estimated returns and allowances, ship and credit claims and other adjustments are provided for in the same period the related revenue are recognized, and are netted against revenue. For non-quality related returns, the Company recognizes a related asset for the right to recover returned products with a corresponding reduction to cost of goods sold. The Company records a reserve for cash discounts as a reduction to accounts receivable and a reduction to revenue, based on the experience with each customer.

Frequently, the Company receives orders with multiple delivery dates that may extend across reporting periods. Each delivery constitutes an individual performance obligation, which consists of transferring control of the products to the customers based on their stand-alone selling price. The Company invoices the customer for each delivery upon shipment and recognizes revenue in accordance with delivery terms. As scheduled delivery dates are within one year, revenue allocated to future shipments of partially completed contracts are not disclosed.

The Company records freight and handling costs associated with outbound freight after control over a product has transferred to a customer as a fulfillment cost and includes it in cost of revenue. Taxes assessed by government authorities on revenue-producing transactions, including value-added and excise taxes, are presented on a net basis (excluded from revenue).

The Company generally warrants that products sold to its customers will, at the time of shipment, be free from defects in workmanship and materials and conform to specifications. The Company’s standard warranty extends for a period of two years from the date of delivery, except in the case of image sensor products, which are warrantied for one year from the date of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

delivery. At the time revenue is recognized, the Company establishes an accrual for estimated warranty expenses associated with its sales and records them as a component of the cost of revenue.

Research and Development Costs

Research and development costs are expensed as incurred.

Income Taxes

Income taxes are accounted for using the asset and liability method. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which management cannot conclude that it is more likely than not that such deferred tax assets will be realized.

In determining the amount of the valuation allowance, estimated future taxable income, feasible tax planning strategies, future reversals of existing temporary differences and taxable income in prior carryback years, if a carryback is permitted, are considered. If the Company determines it is more likely than not that all or a portion of the remaining deferred tax assets will not be realized, the valuation allowance will be increased with a charge to income tax expense. Conversely, if the Company determines it is more likely than not to be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be recorded as a reduction to income tax expense.

The Company recognizes and measures benefits for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that is it more likely than not that the tax positions will be sustained upon audit, including resolution of any related appeals or litigation processes. For tax positions that are more likely than not to be sustained upon audit, the second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon settlement. No tax benefit is recognized for tax positions that are not more likely than not to be sustained. The Company's practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Significant judgment is required to evaluate uncertain tax positions. Evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of tax audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in significant increases or decreases in income tax expense in the period in which the change is made, which could have a significant impact to the Company's effective tax rate.

Foreign Currencies

Most of the Company's foreign subsidiaries conduct business primarily in U.S. dollars and, as a result, utilize the U.S. dollar as their functional currency. For the remeasurement of financial statements of these subsidiaries, assets and liabilities in foreign currencies that are receivable or payable in cash are remeasured at current exchange rates, while inventories and other non-monetary assets in foreign currencies are remeasured at historical rates. Gains and losses resulting from the remeasurement of such financial statements are included in the operating results, as are gains and losses incurred on foreign currency transactions.

Some of the Company's Japanese subsidiaries utilize Japanese Yen as their functional currency. The assets and liabilities of these subsidiaries are translated at current exchange rates, while revenue and expenses are translated at the average rates in effect for the period. The related translation gains and losses are included in other comprehensive income or loss within the Consolidated Statements of Operations and Comprehensive Income.

Share-Based Compensation

Share-based compensation is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee's requisite service period and for awards with performance conditions, over the performance measurement period. The Company has outstanding awards that vest based on service, performance and market conditions.

Defined Benefit Pension Plans

The Company maintains defined benefit pension plans covering certain of its foreign employees. Net periodic pension costs and

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

pension obligations are determined based on actuarial assumptions, including discount rates for plan obligations, assumed rates of return on pension plan assets and assumed rates of compensation increases for employees participating in plans. These assumptions are based upon management's judgment and consultation with actuaries, considering all known trends and uncertainties. The service cost component of the net periodic pension cost is allocated between the cost of revenue, research and development, selling and marketing and general and administrative line items, while the other components are included in other expense in the Consolidated Statements of Operations and Comprehensive Income.

Fair Value Measurement

The Company measures certain of its financial and non-financial assets at fair value by using the fair value hierarchy that prioritizes certain inputs into individual fair value measurement approaches. Fair value is the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, as follows:

  • Level 1 - Quoted prices in active markets for identical assets or liabilities;

  • Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

  • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Companies may choose to measure certain financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected must be reported in earnings. The Company has elected not to carry any of its debt instruments at fair value.

Note 3: Revenue and Segment Information

Revenue recognized for product sales amounted to $5,227.8 million, $5,492.0 million and $5,849.0 million for the years ended December 31, 2020, 2019 and 2018, respectively. Revenue recognized for product development agreements amounted to $27.2 million, $25.9 million and $29.3 million for the years ended December 31, 2020, 2019 and 2018, respectively.

The Company is organized into three operating and reportable segments consisting of PSG, ASG and ISG. The Company's wafer manufacturing facilities fabricate ICs for all business units, as necessary, and their operating costs are reflected in the segments' cost of revenue on the basis of product costs. Because operating segments are generally defined by the products they design and sell, they do not make sales to each other. The Company does not allocate income taxes or interest expense to its operating segments as the operating segments are principally evaluated on gross profit. Additionally, restructuring, asset impairments and other charges, net and certain other manufacturing and operating expenses, which include corporate research and development costs, unallocated inventory reserves and miscellaneous nonrecurring expenses, are not allocated to any segment. In addition to the operating and reportable segments, the Company also operates global operations, sales and marketing, information systems and finance and administration groups. A portion of the expenses for each of these groups are allocated to the segments based on specific and general criteria and are included in the segment results.

The Company operates in various geographic locations. Sales to unaffiliated customers have little correlation with the location of manufacturers. It is, therefore, not meaningful to present operating profit by geographical location.

The Company does not discretely allocate assets to its operating segments, nor does management evaluate operating segments using discrete asset information. The Company’s consolidated assets are not specifically ascribed to its individual reportable segments. Rather, assets used in operations are generally shared across the Company’s operating and reportable segments.

Note 4: Recent Accounting Pronouncements

Adopted:

ASU 2020-04 – Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04")

In March 2020, the FASB issued ASU 2020-04 to address constituents’ concerns about certain accounting consequences that could result from the global markets’ anticipated transition away from the use of the LIBO Rate and other interbank offered rates to alternative reference rates. ASU 2020-04 includes optional expedients and the relief provided is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBO Rate or another reference rate expected to be discontinued because of reference rate reform. These amendments are effective for entities as of March 12, 2020 through December 31, 2022. The Company elected to apply the provisions of ASU 2020-04 for its contracts and hedging relationships as of March 12, 2020. The adoption of ASU 2020-04 did not have a material impact on the Company's consolidated financial statements.

ASU 2019-12 – Income taxes (Topic 740): Simplifying the accounting for income taxes ("ASU 2019-12")

In December 2019, the FASB issued ASU 2019-12, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Income taxes (Topic 740). The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company early adopted ASU 2019-12 during the quarter ended April 3, 2020. The adoption of ASU 2019-12 did not have a material impact on the Company's consolidated financial statements.

ASU 2018-14 – Defined Benefit Plans – General (Topic 715-20): Disclosure Framework – Changes to the Disclosure Requirements of Defined Benefit Plans ("ASU 2018-14")

During 2018, the FASB issued ASU 2018-14, which amended ASC 715: Compensation - Retirement Benefits, to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. ASU 2018-14 added requirements to disclose, among others, a narrative description of the reasons for significant gains and losses affecting the benefit obligation for the period, and also removed certain other disclosure requirements. For public business entities, the provisions of ASU 2018-14 is effective for fiscal years ending after December 15, 2020. The adoption of ASU 2018-14 did not have a material impact on the Company’s consolidated financial statements.

ASU No. 2016-02 - Leases (Topic 842) ("ASU 2016-02"), ASU No. 2018-10 - Codification improvements to Topic 842, Leases ("ASU 2018-10"), ASU No. 2018-11 - Leases (Topic 842) ("ASU 2018-11") (collectively, the "New Leasing Standard")

The New Leasing Standard became effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted the New Leasing Standard as of January 1, 2019 using the effective date method by recording right-of-use assets of $112.3 million, net of deferred rent liabilities of $5.1 million that were reclassified to right-of-use assets, and lease liabilities of $117.4 million. Under this method, periods prior to 2019 remain unchanged. The Company applied the practical expedients relating to the leases that commenced before January 1, 2019 whereby the Company elected to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases.

Pending Adoption:

ASU 2020-06 - Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06")

In August 2020, the FASB issued ASU 2020-06, which simplifies the guidance on the issuer’s accounting for convertible debt instruments by removing the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. As a result, entities will not separately present in equity an embedded conversion feature in such debt and will account for a convertible debt instrument wholly as debt, unless certain other conditions are met. The elimination of these models will reduce reported interest expense and increase reported net income for entities that have issued a convertible instrument that is within the scope of ASU 2020-06. Also, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and the treasury stock method will be no longer available. ASU 2020-06 is applicable for fiscal years beginning after December 15, 2021, with early adoption permitted no earlier than fiscal years beginning after December 15, 2020. The Company does not intend to early adopt ASU 2020-06; however, based on the application of the new standard on the 1.625% Notes, there would be a decrease in interest expense and an increase in the dilutive effect of convertible notes included in diluted weighted average shares of common stock outstanding for calculating earnings per share.

Note 5: Acquisitions, Divestiture and Licensing Transactions

The Company pursues strategic acquisitions and divestitures from time to time to leverage its existing capabilities and further build its business. Acquisition costs are not included as components of consideration transferred and instead are accounted for as expenses in the period in which the costs are incurred. During the years ended December 31, 2020 and 2019, the Company incurred acquisition and divestiture related costs of approximately $1.0 million and $11.3 million, respectively, which are included in operating expenses in the Company's Consolidated Statements of Operations and Comprehensive Income. The decrease in 2020 was due to the lack of any significant acquisition-related activities.

Pending Acquisition of Manufacturing Facility and Related Assets

On April 22, 2019, the Company entered into the Asset Purchase Agreement with GFUS and GLOBALFOUNDRIES Inc. pursuant to which the Company will acquire GFUS’s East Fishkill, New York site and fabrication facilities and certain other assets and liabilities on or around the Closing Date, subject to certain conditions, for the Total Consideration of $400.0 million. On April 22, 2019, the Company paid GFUS $70.0 million of the Total Consideration in cash as a non-refundable deposit, which will be applied toward and reduce the Total Consideration.

Also on April 22, 2019, the parties entered into certain ancillary agreements pursuant to which, the Company will be provided with technology transfer and development services as well as foundry services prior to the Closing Date, and GFUS will be

provided foundry services for a limited period of time following the Closing Date, and the Company paid GFUS a license fee of $30.0 million in cash for certain technology. This amount has been recorded as an intangible asset in the Consolidated Balance Sheets.

On October 1, 2020, the Company entered into an amendment to the APA Amendment pursuant to which the Company paid GFUS a non-refundable deposit in the amount of $100.0 million in cash on October 5, 2020 (the "Additional Deposit"). The Additional Deposit will be applied toward and reduce the Total Consideration, and the remaining $230.0 million of the Total Consideration will be paid on or around the Closing Date. Other terms and conditions of the Asset Purchase Agreement remain unchanged. In connection with the APA Amendment, the Company also entered into an amendment to an ancillary agreement relating to the provision of foundry services entered into in connection with the execution of the Asset Purchase Agreement, which provides the Company certain additional tools and flexibility in its capital expenditures and manufacturing plans for 2021.

2019 Acquisition

On June 19, 2019, the Company acquired 100% of the outstanding shares of Quantenna, a global leader and innovator of high performance Wi-Fi solutions, whereby Quantenna became a wholly-owned subsidiary of the Company. The acquisition of Quantenna created a strong platform for addressing connectivity solutions for industrial IoT by combining the Company's expertise in power management and Bluetooth technologies with Quantenna's Wi-Fi technologies and software capabilities. Following the acquisition, Quantenna changed its name to ON Semiconductor Connectivity Solutions, Inc.

The purchase price consideration for the acquisition totaled $1,039.3 million, and was funded by a combination of a draw of $900.0 million against the Revolving Credit Facility and cash on hand. From the closing date of the Quantenna acquisition through December 31, 2019, the Company recognized approximately $84.8 million in revenue and $39.3 million in net loss relating to Quantenna, which included the amortization of fair market value step-up of inventory and intangible assets and restructuring charges. The operations of Quantenna have since been integrated with that of the Company.

The following table presents the allocation of the purchase price of Quantenna for the assets acquired and liabilities assumed based on their relative fair values, which was finalized during the year ended December 31, 2019 (in millions):

IPRD assets are amortized over the estimated useful life of the assets upon successful completion of the related projects. The value assigned to IPRD was determined by estimating the net cash flows from the projects when completed and discounting the net cash flows to their present value using a discount rate of approximately 12.0%. The cash flows from IPRD’s significant products commenced from 2020 onwards.

The acquisition produced $726.7 million of goodwill, which has been assigned to a reporting unit within ASG. The goodwill is attributable to a combination of Quantenna's assembled workforce, expectations regarding a more meaningful engagement by the customers due to the scale of the combined company and other product and operating synergies. Goodwill arising from the Quantenna acquisition is not deductible for tax purposes.

Year ended December 31, 2020:

Voluntary Separation Program

During the first quarter of 2020, the Company offered the VSP to employees that met certain criteria. Participation was subject to management review and approval. The purpose of the VSP was to allow employees to voluntarily separate employment during a specific time and with enhanced separation compensation and benefits, thereby enabling the Company to optimize its cost structure and progress towards its target financial model. Management approved 243 employees for participation in the VSP during the first quarter, after which the VSP was terminated. The aggregate expense for the VSP amounted to $27.5 million for the 243 employees, all of whom had exited by the end of the second quarter of 2020. All amounts under the VSP have been paid during 2020, and there are no payments remaining as of December 31, 2020.

2020 Involuntary Separation Program

During the second quarter of 2020, the Company implemented the ISP restructuring program. Under the ISP, the Company notified approximately 191 employees of their employment termination with aggregate severance costs and other benefits amounting to $11.8 million. All notified employees have exited during 2020 and an insignificant amount remained accrued as of December 31, 2020. The Company currently does not anticipate additional employee terminations under this program.

General workforce reduction

In addition to the VSP and the ISP, the Company undertook certain general workforce reduction measures during 2020.

During the first three quarters of 2020, the Company notified approximately 153 employees of their employment termination with aggregate severance costs and other benefits amounting $6.2 million. All notified employees have exited during 2020 and an insignificant amount remained accrued as of December 31, 2020.

During the fourth quarter of 2020, the Company notified approximately 106 employees of their employment termination with aggregate severance costs and other benefits amounting to approximately $6.1 million, of which 67 employees have exited as of the end of the year. As of December 31, 2020, $5.3 million remained accrued and is expected to be paid during the first quarter of 2021.

Year ended December 31, 2019:

General workforce reductions and post-Quantenna acquisition restructuring

During the first quarter of 2019, the Company approved and began to implement certain restructuring actions aimed at cost savings, primarily through workforce reductions. As of December 31, 2019, the Company had notified approximately 143 employees of their employment termination, all of whom had exited by December 31, 2019. For the year ended December 31, 2020, the expense for this program amounted to $8.4 million, all of which was paid as of December 31, 2019.

Following the acquisition of Quantenna and during the quarter ended June 28, 2019, the Company implemented a cost-reduction plan resulting in the elimination of approximately eight executive positions from Quantenna’s workforce, primarily as a result of redundancies. During the year ended December 31, 2019, the Company terminated an additional ten employees. The total restructuring expense of $15.7 million was attributable to the accelerated vesting of stock awards previously issued by Quantenna, executive retention and other severance benefits. All severance benefits for this program were paid as of December 31, 2019.

Year ended December 31, 2018:

The Company did not have any significant restructuring activities during the year ended December 31, 2018.

The Company continues to evaluate employee positions and locations for potential efficiencies and may incur additional charges in the future.

Amended Credit Agreement

The Company obtained capital for the acquisition of Fairchild and other general corporate purposes under a Credit Agreement dated as of April 15, 2016, by and among the Company, as borrower, the several lenders party thereto, Deutsche Bank AG, New York Branch, as administrative agent and collateral agent, and certain other parties (as subsequently amended, the "Amended Credit Agreement"). The Amended Credit Agreement provides for a $1.97 billion revolving credit facility (the "Revolving Credit Facility") and a $2.4 billion term loan "B" facility (the “Term Loan "B" Facility”).

Amendments to the Amended Credit Agreement

Between 2016 and 2019, the Company, the Guarantors (as defined in the Amended Credit Agreement), the several lenders party thereto and the Agent (as defined in the Amended Credit Agreement) entered into seven amendments to the Amended Credit Agreement. These amendments, among others, reduced the interest rates payable under the Term Loan "B" Facility and the Revolving Credit Facility, increased the amounts that may be borrowed under the Term Loan "B" Facility and the Revolving Credit Facility and also amended certain financial covenants. As part of the seventh amendment to the Amended Credit Agreement executed during 2019, the Company drew an additional $500.0 million under Term Loan "B" Facility and utilized the additional borrowings to repay $500.0 million of the outstanding balance under the Revolving Credit Facility. The maturity date of borrowings under the Revolving Credit Facility and Term Loan "B" Facility currently is June 12, 2024 and September 19, 2026, respectively.

On June 23, 2020, the Company entered into the Eighth Amendment ("Eighth Amendment") to the Amended Credit Agreement to change certain defined terms and to modify certain terms and conditions of the Amended Credit Agreement to align with the domestication of certain foreign subsidiaries. There was no impact to the consolidated financial statements due to the Eighth Amendment. See Note 16: ''Income Taxes'' for additional information on the domestication.

The obligations under the Amended Credit Agreement are guaranteed by the Guarantors and collateralized by a pledge of substantially all of the assets of the Company and the Guarantors, including a pledge of the equity interests in certain of the Company’s domestic and first tier foreign subsidiaries, subject to customary exceptions. The obligations under the Amended Credit Agreement are also collateralized by mortgage on certain real property assets of the Company and its domestic subsidiaries.

The Amended Credit Agreement includes a maximum total net leverage ratio as a financial maintenance covenant, which the Company was in compliance as of December 31, 2020. It also contains other customary affirmative and negative covenants and events of default.

Loss on debt refinancing and prepayment

In connection with an amendment during 2019, the Company incurred fees to lenders, third parties, legal and other costs amounting to $17.5 million, of which a significant portion was capitalized. Management recorded a loss on debt refinancing amounting to $5.8 million, which included a proportionate write-off of the unamortized debt discount and issuance costs and the third party fees incurred for the transaction. In connection with another amendment during 2019, the Company incurred third party, legal and other fees of $6.6 million and recorded $0.4 million as loss on extinguishment of debt, while capitalizing the remaining cost incurred.

The loss on debt refinancing and prepayment amounted to $6.2 million for the year ended December 31, 2019. No such losses were recorded during the year ended December 31, 2020.

Borrowing and repayments under the Revolving Credit Facility

On March 24, 2020, the Company borrowed $1,165.0 million under the Revolving Credit Facility as a precautionary measure in order to increase the Company’s cash position and provide financial flexibility in light of the uncertainty resulting from the impact of the COVID-19 pandemic. Due to better macroeconomic and business conditions, on August 21, 2020, the Company used the net proceeds from the issuance of the 3.875% Notes along with cash on hand to repay $1,200 million of such outstanding borrowings. Additionally, on December 31, 2020, the Company repaid $65.0 million of outstanding borrowings under the Revolving Credit Facility. As of December 31, 2020, approximately $1,269.0 million was available for future borrowings under the Revolving Credit Facility.

Issuance of 3.875% Notes

On August 21, 2020, the Company completed its private offering of $700.0 million aggregate principal amount of the 3.875% Notes. The 3.875% Notes were offered in the United States to qualified institutional buyers pursuant to Rule 144A under the Securities Act and outside the United States pursuant to Regulation S under the Securities Act. The 3.875% Notes are fully and unconditionally guaranteed, on a joint and several basis, by each of the Company’s subsidiaries that is a borrower or Guarantor under the Amended Credit Agreement and will also be fully and unconditionally guaranteed by any of the Company’s subsidiaries that becomes a borrower or guarantees any indebtedness under the Amended Credit Agreement in the future.

The 3.875% Notes and the guarantees thereof are the Company’s and the Guarantors’ general unsecured obligations, respectively, and (i) rank equally in right of payment with all of the Company’s and the Guarantors’ existing and future senior indebtedness (including the 1.625% Notes); (ii) rank senior to any subordinated indebtedness that the Company or the Guarantors may incur; (iii) are effectively subordinated to all of the Company’s or the Guarantors’ existing and future secured indebtedness (including indebtedness under the Amended Credit Agreement), in each case, to the extent of the value of the assets securing such indebtedness; and (iv) are structurally subordinated in right of payment to all existing and future obligations of the Company’s subsidiaries that are not Guarantors of the 3.875% Notes.

The 3.875% Notes bear interest at a rate of 3.875% per year, payable semi-annually on March 1 and September 1 of each year, beginning on March 1, 2021, and will mature on September 1, 2028, unless earlier redeemed or repurchased by the Company. The original issue discount and debt issuance costs incurred by the Company in connection with the offering of the 3.875% Notes amounted to $9.4 million, which has been capitalized and will be amortized to interest expense through the maturity date of September 1, 2028. The net proceeds from the issuance of the 3.875% Notes were used entirely to repay borrowings under the Revolving Credit Facility.

Maturity and Settlement of 1.00% Notes due 2020

The 1.00% Notes matured on December 1, 2020. The maturity of the notes resulted in the Company paying $690.0 million in cash to holders of the 1.00% Notes, representing the principal portion of the 1.00% Notes, using the available cash and cash equivalents.

The excess over the principal amount was settled on December 1, 2020 by issuing shares of the Company's common stock held in treasury. The transaction resulted in a net impact of $88.7 million to additional paid-in capital and treasury stock, measured based on the acquisition cost of the reissued shares with no overall impact to equity. At the time of issuance of the 1.00% Notes, the Company concurrently entered into hedge transactions with certain of the initial purchasers of the 1.00% Notes. According to the terms of these hedge contracts, on December 1, 2020, the Company repurchased an equivalent amount of shares of its common stock at the prevailing fair market value, to effectively offset the issuance of shares, which resulted in an impact of $321.0 million to additional paid-in capital and treasury stock, with no overall impact to equity.

Also at the time of issuance of the 1.00% Notes, the Company sold warrants to certain bank counterparties whereby the holders of the warrants have the option to purchase the equivalent number of shares of the Company’s common stock at a price of $25.96 per share from the Company. These warrants can be exercised by the holders beginning in March and expire no later than April 2021. The Company currently anticipates the holders to exercise the warrants to purchase up to 37.3 million shares of common stock from the Company, which will be settled on a net-share basis depending on the average stock price on the day of exercise.

1.625% Notes due 2023

On March 31, 2017, the Company completed a private placement of $575.0 million of its 1.625% Notes to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 1.625% Notes are governed by an indenture between the Company, as the issuer, the guarantors named therein and Wells Fargo Bank, National Association, as trustee (the "1.625% Indenture"). The 1.625% Notes are convertible by holders into cash and shares of the Company’s common stock at a conversion rate of 48.2567 shares of common stock per $1,000 principal amount of notes (subject to adjustment in certain events), which is equivalent to an initial conversion price of $20.72 per share of common stock. The Company will settle conversion of all 1.625% Notes validly tendered for conversion in cash, shares of the Company’s common stock or a combination of cash and shares to be determined by the Company.

Holders may convert their 1.625% only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on June 30, 2017 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading

days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the 1.625% Notes for each trading day of such period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (iii) upon the occurrence of specified corporate transactions described in the 1.625% Indenture; or (iv) on or after July 15, 2023 (each considered a "trigger"). Upon conversion of the 1.625% Notes, the Company will deliver cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election.

The last reported sale price of the Company’s common stock for at least 20 trading days during the period of 30 consecutive trading days ending on December 31, 2020 was greater than or equal to $26.94 (130% of the conversion price) on each applicable trading day. As a result, the Company recorded the outstanding balance of the 1.625% Notes amounting to $515.6 million, net of unamortized discount and issuance costs, as a current portion of long-term debt as of December 31, 2020, and as required by the 1.625% Indenture, gave notice to the trustee, the conversion agent and each holder on December 31, 2020 that each holder has the right to surrender any portion of its 1.625% Notes (in minimum denominations of $1,000 in principal amount or an integral multiple thereof) for conversion during the calendar quarter ending March 31, 2021 (and only during such calendar quarter unless the trigger remains) pursuant to the terms of the 1.625% Indenture.

Other Long-term Debt

Note Payable to Fujitsu

On October 1, 2018, the Company assumed a yen-denominated non-collateralized loan obligation amounting to $50.6 million as a result of the Company acquiring a majority ownership in OSA. Amortization and maturity of the loan was at the request of the lender, FSL. Upon acquiring 100% ownership in OSA, the Company repaid the balance in full during the year ended December 31, 2020.

Note 10: Earnings Per Share and Equity

Earnings Per Share

Net income per share of common stock attributable to ON Semiconductor Corporation is shown below (in millions, except per share data):

Year ended December 31,
202020192018
Net income attributable to ON Semiconductor Corporation$234.2$211.7$627.4
Basic weighted-average shares of common stock outstanding410.7410.9423.8
Add: Incremental shares for:
Dilutive effect of share-based awards1.91.94.3
Dilutive effect of convertible notes and warrants6.23.27.8
Diluted weighted average shares of common stock outstanding418.8416.0435.9
Net income per share of common stock attributable to ON Semiconductor Corporation:
Basic$0.57$0.52$1.48
Diluted$0.56$0.51$1.44

Basic income per share of common stock is computed by dividing net income attributable to the Company by the weighted average number of shares of common stock outstanding during the period.

To calculate the diluted weighted-average shares of common stock outstanding, treasury stock method has been applied to calculate the number of incremental shares from the assumed issuance of shares relating to RSUs. Share-based awards of approximately 0.8 million, 0.8 million and 0.6 million for the years ended December 31, 2020, 2019 and 2018, respectively, were excluded as the impact was considered to be anti-dilutive.

The dilutive impact related to the Company’s 1.00% Notes and 1.625% Notes, for the period such notes were outstanding, has

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

been determined in accordance with the net share settlement requirements, under which the Company’s convertible notes are assumed to be convertible into cash up to the par value, with the excess of par value being convertible into common stock. The 1.00% Notes matured and were repaid and settled on December 1, 2020. While the dilutive impact of the warrants that were issued concurrently with the issuance of the 1.00% Notes which have an exercise price of $25.96 have been included in the calculation of diluted weighted-average common shares outstanding, the warrants issued concurrently with the issuance of the 1.625% Notes which have an exercise price of $30.70 were still anti-dilutive and excluded. Prior to conversion, the convertible note hedges are not considered for purposes of the earnings per share calculations, as their effect would be anti-dilutive. Upon conversion, the convertible note hedges are expected to offset the dilutive effect of the 1.625% Notes when the stock price is above $20.72 per share.

Equity

Share Repurchase Programs

On December 1, 2014, the Company announced the "Capital Allocation Policy" under which the Company intends to return to stockholders approximately 80 percent of free cash flow, less repayments of long-term debt, subject to a variety of factors, including the strategic plans, market and economic conditions and the discretion of the Board of Directors. For the purposes of the Capital Allocation Policy, the Company defines "free cash flow" as net cash provided by operating activities less purchases of property, plant and equipment.

On December 1, 2014, the Company announced the 2014 Share Repurchase Program pursuant to the Capital Allocation Policy. Under the Company’s 2014 Share Repurchase Program, the Company had the ability to repurchase up to $1.0 billion (exclusive of fees, commissions and other expenses) of the Company’s common stock over a period of four years from December 1, 2014, subject to certain contingencies. The 2014 Share Repurchase Program, which did not require the Company to purchase any particular amount of common stock and was subject to the discretion of the Board of Directors, expired on November 30, 2018 with approximately $288.2 million remaining unutilized. The Company repurchased common stock for an aggregate purchase price of approximately $315.0 million under the 2014 Share Repurchase Program during the year ended December 31, 2018.

On November 15, 2018, the Company announced the 2018 Share Repurchase Program pursuant to the Capital Allocation Policy. Under the 2018 Share Repurchase Program, the Company is authorized to repurchase up to $1.5 billion of its common shares from December 1, 2018 through December 31, 2022, exclusive of any fees, commissions or other expenses. The Company may repurchase its common stock from time to time in privately negotiated transactions or open market transactions, including pursuant to a trading plan in accordance with Rule 10b5-1 and Rule 10b-18 of the Exchange Act, or by any combination of such methods or other methods. The timing of any repurchases and the actual number of shares repurchased will depend on a variety of factors, including the Company’s stock price, corporate and regulatory requirements, restrictions under the Company’s debt obligations and other market and economic conditions. There were $65.3 million and $138.9 million in repurchases of the Company's common stock under the 2018 Share Repurchase Program during the years ended December 31, 2020 and December 31, 2019, respectively. As of December 31, 2020, the remaining authorized amount under the 2018 Share Repurchase Program was $1,295.8 million.

Information relating to the Company's 2018 and 2014 Share Repurchase Programs is as follows (in millions, except per share data):

Reissuance of shares held in treasury stock

In connection with the maturity of the 1.00% Notes, the Company reissued shares of common stock held in treasury to settle the excess over the principal amount. This was the first time the Company reissued shares held in treasury stock and accounted for such reissuance on a first-in, first-out basis. Pursuant to the hedge transactions entered concurrently with the issuance of the 1.00% Notes, the Company repurchased an equivalent number of shares of its common stock at the prevailing fair market value, to effectively offset the reissuance from treasury stock. This repurchase did not reduce the authorized amount remaining under the 2018 Share Repurchase Program.

Shares for Restricted Stock Units Tax Withholding

Treasury stock is recorded at cost and is presented as a reduction of stockholders’ equity in the accompanying consolidated financial statements. Shares with a fair market value equal to the applicable amount of the employee withholding taxes due are withheld upon the vesting of RSUs to pay the applicable amount of employee withholding taxes and are considered common stock repurchases. The Company then pays the applicable amount of withholding taxes in cash. The amounts remitted during the years ended December 31, 2020, 2019 and 2018 were $20.0 million, $33.5 million and $31.6 million, respectively, for which the Company withheld approximately 1.1 million, 1.6 million and 1.3 million shares of common stock, respectively, that were underlying the RSUs that vested. None of these shares had been reissued or retired as of December 31, 2020, but may be reissued or retired later. These deemed repurchases in connection with tax withholding upon vesting were not made under the 2018 Share Repurchase Program or 2014 Share Repurchase Program, and the amounts spent in connection with such deemed repurchases did not reduce the authorized amount remaining under the 2018 Share Repurchase Program.

Non-Controlling Interest

Leshan operates assembly and test operations in Leshan, China. The Company owns 80% of the outstanding equity interests in Leshan, and the results of Leshan have been consolidated in the Company's financial statements. At December 31, 2020, the Leshan non-controlling interest balance was $19.6 million. This balance included the Leshan non-controlling interest's $2.2 million share of the earnings for the year ended December 31, 2020 offset by $5.0 million of dividends paid to the non-controlling shareholder. At December 31, 2019, the Leshan non-controlling interest balance was $22.4 million. This balance included the Leshan non-controlling interest's $2.2 million share of the earnings for the year ended December 31, 2019 offset by $2.3 million of dividends paid to the non-controlling shareholder.

OSA operates a front-end wafer fabrication facility in Aizuwakamatsu, Japan. During 2018, the Company acquired an incremental 50% equity interest in OSA for approximately $24.6 million, net of cash acquired, to increase its ownership to 60% of the outstanding equity interest. During 2020, the Company acquired the remaining 40% of the equity interest in OSA from FSL, whereby OSA became a wholly-owned subsidiary of the Company. The purchase price payable to FSL for the remaining 40% equity, offset by the purchase price adjustment, resulted in the Company receiving $26.0 million in settlement of the purchase price from FSL during the year ended December 31, 2020. The results of OSA have been consolidated in the Company’s financial statements since 2018 when the Company became the majority owner.

Stockholders' Rights Plan

On June 7, 2020, the Board of Directors authorized and declared a dividend of one preferred share purchase right (a "Right") to be issued as of 5:00 p.m. New York City time on June 18, 2020 for each outstanding share of common stock to the stockholders of record on that date. In connection with the Rights, the Company and Computershare Trust Company, N.A., as rights agent, entered into a Rights Agreement, dated as of June 8, 2020 (the "Rights Agreement"). Each Right entitles the registered holder of common stock to purchase from the Company one one-hundred-thousandth of a share (a "Unit") of Series B Junior Participating Preferred Stock, par value $0.01 per share, at a purchase price of $100.80 per Unit (the "Purchase Price"), subject to adjustment as provided in the Rights Agreement. Subject to certain exceptions, if a person or group becomes the beneficial owner of more than 15% of the Company’s outstanding shares of common stock, the Rights will become exercisable for that number of shares of Common Stock having a market value of two times the Purchase Price. The Rights, which have a de minimis value as of December 31, 2020, expire on the earlier of (i) the close of business on June 7, 2021, (ii) the time at which the Rights are redeemed pursuant to the Rights Agreement, (iii) the closing of any merger or other acquisition transaction involving the Company that has been approved by the Board of Directors, at which time the Rights are terminated, and (iv) the time at which the Rights are exchanged pursuant to the Rights Agreement. The Rights are in all respects subject to and governed by the provisions of the Rights Agreement.

At December 31, 2020, total unrecognized share-based compensation expense, net of estimated forfeitures, related to non-vested RSUs with service, performance and market conditions was $74.5 million, which is expected to be recognized over a weighted-average period of 1.6 years. There was an insignificant amount of stock options exercised during the year ended December 31, 2020. Upon option exercise, vesting of RSUs, stock grant awards or completion of a purchase under the ESPP, the Company issues new shares of common stock.

Share-Based Compensation Information

The fair value per unit of RSU and stock grant award is determined on the grant date. There were no employee stock options granted during the years ended December 31, 2020, 2019 and 2018. Share-based compensation expense is based on awards ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The annualized pre-vesting forfeitures for RSUs were estimated to be approximately 5% for the years ended December 31, 2020, 2019 and 2018.

Plan Descriptions

On March 23, 2010, the Company adopted the Amended and Restated SIP, which was subsequently approved by the Company's stockholders at the annual stockholder meeting on May 18, 2010 and reapproved by the Company’s stockholders at the annual stockholder meeting on May 20, 2015. The Amended and Restated SIP provides key employees, directors and consultants with various equity-based incentives as described in the plan document. The Amended and Restated SIP is administered by the Board of Directors or a committee thereof, which is authorized to determine, among other things, the key employees, directors or consultants who will receive awards under the plan, the amount and type of award, exercise prices or performance criteria, if applicable, and vesting schedules. On May 15, 2012, stockholders approved certain amendments to the Amended and Restated SIP to increase the number of shares of common stock subject to all awards under the Amended and Restated SIP by 33.0 million. On May 17, 2017, stockholders approved certain amendments to the Amended and Restated SIP to increase the number of shares of common stock subject to all awards under the Amended and Restated SIP by 27.9 million to 87.0 million, exclusive of shares of common stock subject to awards that were previously granted pursuant to the 2000 SIP that have or will become available for grant pursuant to the Amended and Restated SIP.

Generally, RSUs granted under the Amended and Restated SIP vest ratably over three years for awards with service conditions and over two years for awards with performance or market conditions, or a combination thereof, and are settled in shares of the Company's common stock upon vesting. Generally, upon the termination of an RSU holder's employment, all unvested RSUs will immediately cancel, except under circumstances where the service condition has been fulfilled.

As of December 31, 2020, there was an aggregate of 16.5 million shares of common stock available for grant under the Amended and Restated SIP.

During 2020, the Company awarded 2.7 million RSUs to certain officers and employees of the Company that vest upon the achievement of certain performance criteria and market conditions. The number of units expected to vest is evaluated each reporting period and compensation expense is recognized for those units for which achievement of the performance criteria is considered probable. Compensation expense for RSUs with market conditions are recognized based on the grant date fair value irrespective of the achievement of the condition.

As of December 31, 2020, unrecognized compensation expense, net of estimated forfeitures related to non-vested RSUs granted under the Amended and Restated SIP with service, performance and market conditions, was $69.7 million, $0.8 million and $4.0 million, respectively. For RSUs with time-based service conditions, expense is being recognized over the vesting period; for RSUs with performance criteria, expense is recognized over the period when the performance criteria is expected to be achieved; for RSUs with market conditions, expense is recognized over the period in which the condition is assessed irrespective of whether it would be achieved or not. Unrecognized compensation cost for awards with certain performance criteria that are not expected to be achieved is not included here. Total compensation expense related to performance-based, service-based, and market-based RSUs was $58.1 million for the year ended December 31, 2020, which included $52.5 million for RSUs with time-based service conditions that were granted in 2020 and prior that are expected to vest.

Employee Stock Purchase Plan

On February 17, 2000, the Company adopted the ESPP.

Employees are limited to annual purchases of $25,000 under this plan. In addition, during each quarterly offering period, employees may not purchase stock exceeding the lesser of: (i) 500 shares; or (ii) the number of shares equal to $6,250 divided by the fair market value of the stock on the first day of the offering period. During the years ended December 31, 2020, 2019 and 2018 employees purchased approximately 1.8 million, 1.7 million and 1.5 million shares, respectively, under the ESPP. On May 17, 2017, stockholders approved an amendment to the Company’s ESPP, which increased the number of shares reserved and available to be issued pursuant to the ESPP to a total of 28.5 million. As of December 31, 2020, there were approximately 3.0 million shares available for issuance under the ESPP. Total compensation expense related to the ESPP for the year ended December 31, 2020 was $8.1 million.

Note 12: Employee Benefit Plans

Defined Benefit Pension Plans

The Company maintains defined benefit pension plans for employees of certain of its foreign subsidiaries. Such plans conform to local practice in terms of providing minimum benefits mandated by law, collective agreements or customary practice. The

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

Company recognizes the aggregate amount of all overfunded plans as assets and the aggregate amount of all underfunded plans as liabilities in its Consolidated Balance Sheets. The Company's expected long-term rate of return on plan assets is updated at least annually, taking into consideration its asset allocation, historical returns on similar types of assets and the current economic environment. For estimation purposes, the Company assumes its long-term asset mix will generally be consistent with the current mix. The Company determines its discount rates using highly rated corporate bond yields and government bond yields.

Benefits under all of the plans are valued utilizing the projected unit credit cost method. The Company's policy is to fund its defined benefit plans in accordance with local requirements and regulations. The funding is primarily driven by the current assessment of the economic environment and projected benefit payments of foreign subsidiaries. The measurement date for determining the defined benefit obligations for all plans is December 31 of each year.

The Company recognizes actuarial gains and losses during the period the Company's annual pension plan actuarial valuations are prepared, which generally occurs during the fourth calendar quarter of each year, or during any interim period where a revaluation is deemed necessary. For the years ended December 31, 2020, 2019 and 2018, the Company recognized actuarial losses amounting to $4.0 million, $15.6 million and $6.1 million, respectively. For 2020, the net actuarial loss of $8.1 million which was primarily due to a decrease in the discount rates and other insignificant changes in actuarial assumptions, was partially offset by better than expected return on plan assets amounting to $4.1 million.

Following is a summary of the status of the Company's foreign defined benefit pension plans and the net periodic pension cost (amounts in millions):

The total underfunded status was $141.9 million at December 31, 2020. The Company expects to contribute $22.1 million during 2021 to its foreign defined benefit plans.

Defined Contribution Plans

The Company has a deferred compensation savings plan for all eligible U.S. employees established under the provisions of Section 401(k) of the Internal Revenue Code (the "Code"). Eligible employees may contribute a percentage of their salary subject to certain limitations. The Company has elected to match 100% of employee contributions between 0% and 4% of their salary, with an annual limit of $11,400. The Company recognized $19.4 million, $18.1 million and $19.2 million of expense relating to matching contributions in 2020, 2019 and 2018, respectively.

Certain foreign subsidiaries have defined contribution plans in which eligible employees participate. The Company recognized compensation expense of $21.8 million, $20.6 million and $20.5 million relating to these plans for the years ended 2020, 2019 and 2018, respectively.

Environmental Contingencies

The Company’s headquarters in Phoenix, Arizona are located on property that is a "Superfund" site, which is a property listed on the National Priorities List and subject to clean-up activities under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"). Motorola and Freescale (acquired by NXP Semiconductors N.V.) have been

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

involved in the clean-up activities of on-site solvent contaminated soil and groundwater and off-site contaminated groundwater pursuant to consent decrees with the State of Arizona. As part of the Company’s separation from Motorola in 1999, Motorola retained responsibility for this contamination, and Motorola and Freescale have agreed to indemnify the Company with respect to remediation costs and other costs or liabilities related to this matter. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be, material.

The Company’s former front-end manufacturing location in Aizu, Japan is located on property where soil and ground water contamination was detected. The Company believes that the contamination originally occurred during a time when the facility was operated by a prior owner. The Company worked with local authorities to implement a remediation plan and has completed remaining remediation. The majority of the cost of remediation was covered by insurance. During 2018, semi-annual groundwater monitoring indicated that the treatment was effective, and accordingly, we ceased such monitoring and have determined that this remediation project is complete. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be material.

The Company’s manufacturing facility in the Czech Republic has undergone remediation to respond to releases of hazardous substances that occurred during the years that this facility was operated by government-owned entities. The remediation projects consisted primarily of monitoring groundwater wells located on-site and off-site with additional action plans developed to respond in the event certain contamination levels are exceeded. The government of the Czech Republic has agreed to indemnify the Company and its respective subsidiaries, subject to specified limitations, for remediation costs associated with this historical contamination. The Company has completed remediation on this project, and accordingly, has ceased all related monitoring efforts. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be material.

The Company’s design center in East Greenwich, Rhode Island is located on property that has localized soil contamination. In connection with the purchase of the facility, the Company entered into a Settlement Agreement and Covenant Not to Sue with the State of Rhode Island. This agreement requires that remedial actions be undertaken and a quarterly groundwater monitoring program be initiated by the former owners of the property. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be material.

As a result of the acquisition of AMIS in 2008, the Company is a "primary responsible party" to an environmental remediation and clean-up plan at AMIS’s former corporate headquarters in Santa Clara, California. Costs incurred by AMIS include implementation of the clean-up plan, operations and maintenance of remediation systems, and other project management costs. However, AMIS’s former parent company, a subsidiary of Nippon Mining, contractually agreed to indemnify AMIS and the Company for any obligations relating to environmental remediation and clean-up activities at this location. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be material.

Through its acquisition of Fairchild, the Company acquired a facility in South Portland, Maine. This facility has ongoing environmental remediation projects to respond to certain releases of hazardous substances that occurred prior to the leveraged recapitalization of Fairchild from its former parent company, National Semiconductor Corporation, which is now owned by Texas Instruments Incorporated. Although the Company may incur certain liabilities with respect to these remediation projects, pursuant to a 1997 asset purchase agreement entered into in connection with the Fairchild recapitalization, National Semiconductor Corporation agreed to indemnify Fairchild, without limitation and for an indefinite period of time, for all future costs related to these projects. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be material.

Under a 1999 asset purchase agreement pursuant to which Fairchild purchased the power device business of Samsung, Samsung agreed to indemnify Fairchild in an amount up to $150.0 million for remediation costs and other liabilities related to historical contamination at Samsung’s Bucheon, South Korea operations. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be material.

Under a 2001 asset purchase agreement pursuant to which Fairchild purchased a manufacturing facility in Mountain Top, Pennsylvania, Intersil Corp. (subsequently acquired by Renesas Electronics Corporation) agreed to indemnify Fairchild for remediation costs and other liabilities related to historical contamination at the facility. Any costs to the Company incurred to respond to the above conditions and projects have not been, and are not expected to be material, and any future payments the Company makes in connection with such liabilities are not expected to be material.

The Company was notified by the EPA that it has been identified as a PRP under CERCLA in the Chemetco Superfund matter. Chemetco, a defunct reclamation services supplier that operated in Hartford, Illinois at what is now a Superfund site, has performed reclamation services for the Company in the past. The EPA is pursuing Chemetco customers for contribution to the site clean-up activities. The Company has joined a PRP group, which is cooperating with the EPA in the evaluation and funding of the clean-up activities. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be material.

Financing Contingencies

In the ordinary course of business, the Company provides standby letters of credit or other guarantee instruments to certain parties initiated by either the Company or its subsidiaries, as required for transactions, including, but not limited to, material purchase commitments, agreements to mitigate collection risk, leases, utilities or customs guarantees. As of December 31, 2020, the Company's Revolving Credit Facility included $15.0 million available for the issuance of letters of credit. There were $0.9 million letters of credit outstanding under the Revolving Credit Facility as of December 31, 2020, which reduced the Company's borrowing capacity. The Company also had outstanding guarantees and letters of credit outside of its Revolving Credit Facility totaling $9.7 million as of December 31, 2020.

As part of obtaining financing in the ordinary course of business, the Company issued guarantees related to certain of its subsidiaries, which totaled $0.9 million as of December 31, 2020. Based on historical experience and information currently available, the Company believes that it will not be required to make payments under the standby letters of credit or guarantee arrangements for the foreseeable future.

Indemnification Contingencies

The Company is a party to a variety of agreements entered into in the ordinary course of business pursuant to which it may be obligated to indemnify the other parties for certain liabilities that arise out of or relate to the subject matter of the agreements. Some of the agreements entered into by the Company require it to indemnify the other party against losses due to IP infringement, property damage (including environmental contamination), personal injury, failure to comply with applicable laws, the Company’s negligence or willful misconduct or breach of representations and warranties and covenants related to such matters as title to sold assets.

The Company faces risk of exposure to warranty and product liability claims in the event that its products fail to perform as expected or such failure of its products results, or is alleged to result, in economic damage, bodily injury or property damage. In addition, if any of the Company’s designed products are alleged to be defective, the Company may be required to participate in their recall. Depending on the significance of any particular customer and other relevant factors, the Company may agree to provide more favorable rights to such customer for valid defective product claims.

The Company and its subsidiaries provide for indemnification of directors, officers and other persons in accordance with limited liability company operating agreements, certificates of incorporation, by-laws, articles of association or similar organizational documents, as the case may be. Section 145 of the Delaware General Corporation Law ("DGCL") authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers under certain circumstances and subject to certain limitations. The terms of Section 145 of the DGCL are sufficiently broad to permit indemnification under certain circumstances for liabilities, including reimbursement of expenses incurred, arising under the Exchange Act. As permitted by the DGCL, the Company’s Amended and Restated Certificate of Incorporation (as amended, the "Certificate of Incorporation"), contains provisions relating to the limitation of liability and indemnification of directors and officers. The Certificate of Incorporation eliminates the personal liability of each of the Company’s directors to the fullest extent permitted by Section 102(b)(7) of the DGCL, as it may be amended or supplemented, and provides that the Company will indemnify its directors and officers to the fullest extent permitted by Section 145 of the DGCL, as amended from time to time.

The Company has entered into indemnification agreements with each of its directors and executive officers. The form of agreement (the "Indemnification Agreement") provides, subject to certain exceptions and conditions specified in the Indemnification Agreement, that the Company will indemnify each indemnitee to the fullest extent permitted by Delaware law against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with a proceeding or claim in which such person is involved because of his or her status as one of the Company’s directors or executive officers. In addition, the Indemnification Agreement provides that the Company will, to the extent not

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

prohibited by law and subject to certain exceptions and repayment conditions, advance specified indemnifiable expenses incurred by the indemnitee in connection with such proceeding or claim.

The Company also maintains directors’ and officers’ insurance policies that indemnify its directors and officers against various liabilities, including certain liabilities under the Exchange Act, which might be incurred by any director or officer in his or her capacity as such.

The agreement and plan of merger relating to the acquisition of Fairchild (the "Fairchild Agreement") provides for indemnification and insurance rights in favor of Fairchild’s then current and former directors, officers and employees. Specifically, the Company has agreed that, for no fewer than six years following the Fairchild acquisition, the Company will: (a) indemnify and hold harmless each such indemnitee against losses and expenses (including advancement of attorneys’ fees and expenses) in connection with any proceeding asserted against the indemnified party in connection with such person’s servings as a director, officer, employee or other fiduciary of Fairchild or its subsidiaries prior to the effective time of the acquisition; (b) maintain in effect all provisions of the certificate of incorporation or bylaws of Fairchild or any of its subsidiaries or any other agreements of Fairchild or any of its subsidiaries with any indemnified party regarding elimination of liability, indemnification of officers, directors and employees and advancement of expenses in existence on the date of the Fairchild Agreement for acts or omissions occurring prior to the effective time of the acquisition; and (c) subject to certain qualifications, provide to Fairchild’s then current directors and officers an insurance and indemnification policy that provides coverage for events occurring prior to the effective time of the acquisition that is no less favorable than Fairchild’s then-existing policy, or, if insurance coverage that is no less favorable is unavailable, the best available coverage.

Similarly, the agreement and plan of merger relating to the acquisition of Quantenna (the "Quantenna Agreement") provides for indemnification and insurance rights in favor of Quantenna’s then current and former directors, officers, employees and agents. Specifically, the Company has agreed that, for no fewer than six years following the Quantenna acquisition, the Company will: (a) indemnify and hold harmless each such indemnified party to the fullest extent permitted by Delaware law in the event of any threatened or actual claim suit, action, proceeding or investigation against the indemnified party based in whole or in part on, or pertaining to, such person’s serving as a director, officer, employee or agent of Quantenna or its subsidiaries or predecessors prior to the effective time of the acquisition or in connection with the Quantenna Agreement; (b) maintain in effect provisions of the certificate of incorporation and bylaws of Quantenna and each of its subsidiaries regarding the elimination of liability of directors and indemnification of officers, directors and employees that are no less advantageous to the intended beneficiaries than the corresponding provisions in the certificate of incorporation and bylaws of Quantenna and each of its subsidiaries in existence on the date of the Quantenna Agreement; and (c) obtain and fully pay the premium for a non-cancelable extension of directors’ and officers’ liability coverage of Quantenna’s directors’ and officers’ policies and Quantenna’s fiduciary liability insurance policies in effect as of the date of the Quantenna Agreement.

While the Company’s future obligations under certain agreements may contain limitations on liability for indemnification, other agreements do not contain such limitations and under such agreements it is not possible to predict the maximum potential amount of future payments due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under any of these indemnities have not had a material effect on the Company’s business, financial condition, results of operations or cash flows. Additionally, the Company does not believe that any amounts that it may be required to pay under these indemnities in the future will be material to the Company’s business, financial position, results of operations, or cash flows.

Legal Matters

From time to time, the Company is party to various legal proceedings arising in the ordinary course of business, including indemnification claims, claims of alleged infringement of patents, trademarks, copyrights and other IP rights, claims of alleged non-compliance with contract provisions and claims related to alleged violations of laws and regulations. The Company regularly evaluates the status of the legal proceedings in which it is involved to assess whether a loss is probable or there is a reasonable possibility that a loss, or an additional loss, may have been incurred and determines if accruals are appropriate. If accruals are not appropriate, the Company further evaluates each legal proceeding to assess whether an estimate of possible loss or range of possible loss can be made for disclosure. Although litigation is inherently unpredictable, the Company believes that it has adequate provisions for any probable and estimable losses. Nevertheless, it is possible that the Company’s consolidated financial position, results of operations or liquidity could be materially and adversely affected in any particular period by the resolution of a legal proceeding. The Company’s estimates do not represent its maximum exposure. Legal expenses related to defense, negotiations, settlements, rulings and advice of outside legal counsel are expensed as incurred.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

The Company is currently involved in a variety of legal matters that arise in the ordinary course of business. Based on information currently available, except as disclosed below, the Company is not involved in any pending or threatened legal proceedings that it believes could reasonably be expected to have a material adverse effect on its financial condition, results of operations or liquidity. The litigation process is inherently uncertain, and the Company cannot guarantee that the outcome of any litigation matter will be favorable to the Company.

Patent Litigation with PI

On October 19, 2019, the Company and PI entered into a Settlement Agreement (the "Settlement Agreement") pursuant to which the parties agreed to withdraw all outstanding legal and administrative disputes on the terms set forth in a binding term sheet previously entered into by and among the Company and PI on October 4, 2019.

Pursuant to the Settlement Agreement, the Company paid PI $175.0 million in cash on October 22, 2019, and the parties have dismissed all previously pending litigation and administrative proceedings. In addition, each party agreed to release the other party from any claims to damages or monetary relief for alleged acts of patent infringement across the various patent infringement litigations and not to file any additional action for legal or equitable relief until June 30, 2023. Neither party granted any licenses to the other.

Litigation with AcBel Polytech, Inc.

On November 27, 2013, Fairchild and Fairchild Semiconductor Corporation were named as defendants in a complaint filed by AcBel Polytech, Inc. ("AcBel") in the U.S. District Court for the District of Massachusetts. The lawsuit alleged a number of causes of action, including breach of warranty, fraud, negligence and strict liability. In parallel to the litigation with AcBel, Fairchild filed an arbitration against its distributor, Synnex Technology International Corp ("Synnex"), in Hong Kong in response to Synnex’s failure to pass along Fairchild’s limited warranty to AcBel.

On July 31, 2020, the Company entered into a settlement agreement and release in respect of the dispute with Synnex and AcBel. On August 6, 2020, the Company paid its full aggregate liability of $6.0 million in accordance with the settlement agreement and all applicable claims were released.

Intellectual Property Matters

The Company faces risk of exposure from claims of infringement of the IP rights of others. In the ordinary course of business, the Company receives letters asserting that the Company’s products or components breach another party’s rights. Such letters may request royalty payments from the Company, that the Company cease and desist using certain IP or other remedies.

The fair value of other long-term debt was estimated based on discounting the remaining principal and interest payments using current market rates for similar debt (Level 2) at December 31, 2020 and December 31, 2019.

Fair Values Measured on a Non-Recurring Basis

Our non-financial assets, such as property, plant and equipment, goodwill and intangible assets are recorded at fair value upon a business combination and are remeasured at fair value only if an impairment charge is recognized. The Company uses unobservable inputs to the valuation methodologies that are significant to the fair value measurements, and the valuations require management's judgment due to the absence of quoted market prices. The Company determines the fair value of its held and used assets, goodwill and intangible assets using an income, cost or market approach as determined reasonable.

As of December 31, 2020 and December 31, 2019, there were no non-financial assets included in the Company's Consolidated Balance Sheet that were remeasured at fair value on a non-recurring basis.

Note 15: Financial Instruments

Foreign Currencies

As a multinational business, the Company's transactions are denominated in a variety of currencies. When appropriate, the Company uses forward foreign currency contracts to reduce its overall exposure to the effects of currency fluctuations on its results of operations and cash flows. The Company's policy prohibits trading in currencies for which there are no underlying exposures and entering into trades for any currency to intentionally increase the underlying exposure. The Company primarily hedges existing assets and liabilities associated with transactions currently on its balance sheet, which are undesignated hedges for accounting purposes.

As of December 31, 2020 and 2019, the Company had outstanding foreign exchange contracts with notional amounts of $263.4 million and $183.3 million, respectively. Such contracts were obtained through financial institutions and were scheduled to mature within one to three months from the time of purchase. Management believes that these financial instruments should not subject the Company to increased risks from foreign exchange movements because gains and losses on these contracts should offset losses and gains on the underlying assets, liabilities and transactions to which they are related.

The following schedule summarizes the Company's net foreign exchange positions in U.S. dollars (in millions):

Amounts receivable or payable under the contracts are included in other current assets or accrued expenses and other current liabilities in the accompanying Consolidated Balance Sheets. For the years ended December 31, 2020, 2019 and 2018, realized and unrealized foreign currency transactions totaled a loss of $6.2 million, $5.0 million and $8.0 million, respectively. The realized and unrealized foreign currency transactions are included in other income (expense) in the Company's Consolidated Statements of Operations and Comprehensive Income.

Cash Flow Hedges

All derivatives are recognized on the balance sheet at their fair value and classified based on each instrument’s maturity date.

Foreign currency risk

The purpose of the Company's foreign currency hedging activities is to protect the Company from the risk that the eventual cash flows resulting from transactions in foreign currencies will be adversely affected by changes in exchange rates. The Company enters into forward contracts that are designated as foreign currency cash flow hedges of selected forecasted payments denominated in currencies other than U.S. dollars.

The Company did not have outstanding derivatives for its foreign currency exposure designated as cash flow hedges as of December 31, 2020 and 2019. See Note 17: ''Changes in Accumulated Other Comprehensive Loss'' for the effective amounts

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

related to derivative instruments designated as cash flow hedges affecting accumulated other comprehensive loss and the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2020.

Interest rate risk

The Company uses interest rate swap contracts to mitigate its exposure to interest rate fluctuations. On April 17, 2020, the Company entered into interest rate swap agreements for notional amounts totaling $1.25 billion (effective as of April 30, 2020) and $750.0 million (effective as of December 31, 2020) and $750.0 million (effective as of December 31, 2021) with maturity dates of December 31, 2020, December 31, 2021 and December 31, 2022, respectively.

The Company did not identify any ineffectiveness with respect to the notional amounts of the interest rate swap contracts effective as of December 31, 2020 and December 31, 2019 amounting to $1.5 billion and $1.0 billion, respectively.

Convertible Note Hedges

The Company entered into convertible note hedges in connection with the issuance of the 1.625% Notes.

Other

At December 31, 2020, the Company had no outstanding commodity derivatives, currency swaps or options relating to either its debt instruments or investments. The Company does not hedge the value of its equity investments in its subsidiaries or affiliated companies. The Company is exposed to credit-related losses if counterparties to hedge contracts fail to perform their obligations. As of December 31, 2020, the counterparties to the Company's hedge contracts are held at financial institutions which the Company believes to be highly rated, and no credit related losses are anticipated.

(1)For the year ended December 31, 2018, this primarily included expense of (i) $31.8 million, or 4.2%, related to the recognition of deferred tax liability for undistributed prior years' earnings of the foreign subsidiaries, (ii) $1.8 million, or 0.3% related to the limitation on deductibility of prior years’ executive compensation, and (iii) $1.5 million, or 0.2% related to the impact of the mandatory repatriation tax. These adjustments were made pursuant to SAB 118.

(2)For the year ended December 31, 2018, this included a one-time benefit of $48.2 million, or 6.4%, related to U.S. tax method changes made during the year that impacted the Company’s GILTI inclusion.

(3)On July 6, 2020, the Company completed a simplification of its corporate structure by repatriating the economic rights of its non-U.S. IP to the United States via domestication of certain foreign subsidiaries (the "Domestication"). The Domestication more closely aligns the Company's corporate structure with its operating structure in accordance with the OECD’s BEPS conclusions and changes to U.S. and European tax laws. The impact of the Domestication, which is regarded as a change in tax status, resulted in a benefit primarily from recognizing certain deferred tax assets, net of deferred tax liabilities, of $63.0 million, or 35.7%.

(4)For the year ended December 31, 2020, this included a benefit of $49.4 million, or 28.0%, for the release of a partial state valuation allowance due to an increase to forecasted domestic income as a result of the Domestication of certain foreign subsidiaries and an expense of $61.8 million, or 35.0%, primarily related to the expiration of Japan net operating losses, netted with the offsetting benefit of $61.8 million, or 35.0%, primarily for the decrease in the related valuation allowance for those same Japan net operating losses. For the year ended December 31, 2019, this included an expense of $11.2 million, or 4.0%, primarily related to the write-off of Hong Kong NOL and expiration of Japan NOL, netted with the offsetting benefit of $11.2 million, or 4.0%, primarily for the decrease in related valuation allowance for those same Hong Kong and Japan NOLs. For the year ended December 31, 2018, this included an expense of $135.2 million, or 17.9%, primarily related to the expiration of Japan NOLs, netted with the offsetting benefit of $135.2 million, or 17.9%, primarily for the decrease in the related valuation allowance for those same Japan NOLs.

The Company’s effective tax rate for 2020 was a benefit of (33.8)%, which differs from the U.S. federal income tax rate of 21%, primarily due to the Domestication of certain foreign subsidiaries and a partial release of state valuation allowance, partially offset by foreign taxes for which the Company will not receive a U.S. tax credit as well as period costs related to the Company's GILTI inclusion.

The Company’s effective tax rate for 2019 was 22.7%, which differs from the U.S. federal income tax rate of 21%, primarily due to foreign taxes for which the Company will not receive a U.S. tax credit as well as period costs related to the Company's GILTI inclusion.

The Company's effective tax rate for 2018 was 16.6%, which differs from the U.S. federal statutory income tax rate of 21% primarily due to a one-time benefit of U.S. tax method changes made during the year that impacted the Company's GILTI inclusion.

(1)The deferred tax assets and liabilities disclosure as of December 31, 2019 has been adjusted to reflect the gross deferred tax right-of-use asset and related gross deferred lease liability recognized in accordance with the New Leasing Standard.

As of December 31, 2020 and 2019, the Company had approximately $99.0 million and $521.9 million, respectively, of federal NOL carryforwards, before reduction for unrecognized tax benefits, which are subject to annual limitations prescribed in Section 382 of the Internal Revenue Code. The decrease is due to current year utilization. If not utilized, a portion of the NOLs will expire in varying amounts from 2028 to 2036; however, a small portion of the NOL that was generated after December 31, 2017 is carried forward indefinitely.

As of December 31, 2020 and 2019, the Company had approximately $153.4 million and $134.5 million, respectively, of federal credit carryforwards, before consideration of valuation allowance or reduction for unrecognized tax benefits, which are subject to annual limitations prescribed in Section 383 of the Internal Revenue Code. If not utilized, the credits will expire in varying amounts from 2028 to 2040.

As of December 31, 2020 and 2019, the Company had approximately $741.3 million and $825.8 million, respectively, of state NOL carryforwards, before consideration of valuation allowance or reduction for unrecognized tax benefits. The decrease is primarily due to current year utilization. If not utilized, a portion of the NOLs will expire in varying amounts starting in 2021. Certain states have adopted the federal rule allowing unlimited NOL carryover for NOLs generated in tax years beginning after December 31, 2017. Therefore, a portion of the state NOLs generated after 2017 carry forward indefinitely. As of December 31, 2020 and 2019, the Company had $141.1 million and $138.6 million, respectively, of state credit carryforwards before consideration of valuation allowance or reduction for unrecognized tax benefits. If not utilized, a portion of the credits will begin to expire in varying amounts starting in 2021.

As of December 31, 2020 and 2019, the Company had approximately $581.6 million and $757.1 million, respectively, of foreign NOL carryforwards, before consideration of valuation allowance. The decrease is primarily due to expiration of Japan NOLs as discussed above. If not utilized, a portion of the NOLs will begin to expire in varying amounts starting in 2021. A significant portion of these NOLs will expire by 2025. As of December 31, 2020 and 2019, the Company had $69.4 million and

$76.8 million, respectively, of foreign credit carryforwards before consideration of valuation allowance. If not utilized, the majority of these credits will expire by 2026.

The Company continues to maintain a valuation allowance of $128.5 million on a portion of its Japan NOLs, which expire in varying amounts from 2021 to 2024. In addition to the valuation allowance on the Japan NOLs, the Company maintains a partial valuation allowance of $72.5 million on its U.S. state deferred tax assets, and a valuation allowance on foreign net operating losses and tax credits in certain other foreign jurisdictions.

At December 31, 2020, 2019 and 2018, respectively, the Company was not indefinitely reinvested with respect to the earnings of its foreign subsidiaries and has therefore accrued withholding taxes that would be owed upon future distributions of such earnings.

The Company maintains liabilities for unrecognized tax benefits. These liabilities involve considerable judgment and estimation and are continuously monitored by management based on the best information available, including changes in tax regulations, the outcome of relevant court cases, and other information. The Company is currently under examination by various taxing authorities. Although the outcome of any tax audit is uncertain, the Company believes that it has adequately provided in its consolidated financial statements for any additional taxes that the Company may be required to pay as a result of such examinations. If the payment ultimately proves not to be necessary, the reversal of these tax liabilities would result in tax benefits being recognized in the period the Company determines such liabilities are no longer necessary. However, if an ultimate tax assessment exceeds the Company's estimate of tax liabilities, additional tax expense will be recorded. The impact of such adjustments could have a material impact on the Company's results of operations in future periods.

The activity for unrecognized gross tax benefits is as follows (in millions):

202020192018
Balance at beginning of year$130.0$112.2$114.8
Acquired balances—15.5—
Additions for tax benefits related to the current year11.99.47.4
Additions for tax benefits of prior years12.38.02.8
Reductions for tax benefits of prior years(1.4)(0.2)(1.9)
Lapse of statute(1.3)(8.2)(10.9)
Settlements(0.5)(6.7)—
Balance at end of year$151.0$130.0$112.2

Included in the December 31, 2020 balance of $151.0 million is $116.0 million related to unrecognized tax benefits that, if recognized, would affect the annual effective tax rate. Also included in the balance of unrecognized tax benefits as of December 31, 2020 is $35.0 million of benefit that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes. Although the Company cannot predict the timing of resolution with taxing authorities, if any, the Company believes it is reasonably possible that its unrecognized tax benefits will be reduced by $48.8 million in the next 12 months due to settlement with tax authorities or expiration of the applicable statute of limitations.

The Company recognized approximately $0.2 million of tax expense for interest and penalties during the year ended December 31, 2020. The Company had approximately $5.3 million, $5.1 million, and $5.1 million of accrued interest and penalties at December 31, 2020, 2019, and 2018, respectively.

Tax years prior to 2017 are generally not subject to examination by the IRS except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. The Company is currently under IRS examination for the 2017 tax year. For state tax returns, the Company is generally not subject to income tax examinations for tax years prior to 2016. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. With respect to jurisdictions outside the United States, the Company is generally not subject to examination for tax years prior to 2010. The Company believes that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with the Company's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs.
