NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1:    Background and Basis of Presentation

ON Semiconductor Corporation, together with its wholly and majority-owned subsidiaries (“ON Semiconductor,” “we,” “us,” “our,” or the “Company”), uses a thirteen-week fiscal quarter accounting period for the first three fiscal quarters of each year, with the first quarter of 2019 having ended on March 29, 2019 and each fiscal year ending on December 31. The quarters ended March 29, 2019 and March 30, 2018 contained 88 and 89 days, respectively. As of March 29, 2019, the Company was organized into the following three operating and reporting segments: the Power Solutions Group (“PSG”), theAnalog Solutions Group (“ASG”) and the Intelligent Sensing Group (“ISG”). Additional details on the Company’s operating and reporting segments are included in Note 2: “Revenue and Segment Information.”

The accompanying unaudited financial statements as of and for the quarter ended March 29, 2019 have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for unaudited interim financial information. Accordingly, the unaudited financial statements do not include all of the information and footnotes required by GAAP for audited financial statements. The balance sheet as of December 31, 2018 was derived from the Company’s audited financial statements but does not include all disclosures required by GAAP for audited financial statements. In the opinion of the Company’s management, the interim information includes all adjustments, which includes normal recurring adjustments, necessary for a fair statement of the results for the interim periods. The footnote disclosures related to the interim financial information included herein are also unaudited. Such financial information should be read in conjunction with the consolidated financial statements and related notes thereto for the year ended December 31, 2018 included in the Company’s Annual Report on Form10-K for the fiscal year ended December 31, 2018, which was filed with the SEC on February 20, 2019 (the “2018 Form10-K”). Financial results for interim periods are not necessarily indicative of the results of operations that may be expected for a full fiscal year.

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) estimates of future payouts for customer incentives and estimates of amounts subject to allowances, returns and warranties; (ii) measurement of valuation allowances relating to inventories; (iii) fair values of share-based compensation and of financial instruments (including derivative financial instruments); and (iv) measurement of valuation allowances against deferred tax assets and evaluations of unrecognized tax benefits. 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 goodwill, indefinite-lived intangible assets and long-lived assets and in assumptions used in connection with business combinations. Actual results may differ from the estimates and assumptions used in the consolidated financial statements and related notes.

Pending Acquisition of Quantenna Communications, Inc.

On March 27, 2019, the Company entered into a definitive Agreement and Plan of Merger (the “Quantenna Agreement”) with each of Quantenna Communications, Inc. (“Quantenna”) and Raptor Operations Sub, Inc., the Company’s wholly-owned subsidiary (“Raptor”), which provides for the proposed merger of Quantenna with Raptor, whereby Quantenna will continue as the surviving corporation and a wholly-owned subsidiary of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

(unaudited)

Pursuant to the terms and conditions set forth in the Quantenna Agreement, at the effective time of the merger (the “Effective Time”), each share of Quantenna’s common stock, par value $0.0001 per share (the “Shares”), outstanding immediately prior to the Effective Time will automatically be canceled and converted into the right to receive $24.50 per Share in cash, without interest. The merger consideration represents equity value of approximately $1.07 billion and enterprise value of approximately $936.0 million, after accounting for Quantenna’s net cash of approximately $136.0 million at the end of fourth quarter of 2018. The Company intends to finance the approximately $1.07 billion of cash consideration with a combination of cash on hand and available capacity under its Revolving Credit Facility.

The Quantenna Agreement has been adopted by the boards of directors of each of ON Semiconductor and Quantenna, and the board of directors of Quantenna has recommended that stockholders of Quantenna adopt the Quantenna Agreement. No approval of the Company’s stockholders is required in connection with the transaction.

A detailed description of the transactions contemplated by the Quantenna Agreement can be found in the Form8-K filed by the Company with the SEC on March 27, 2019. The Company currently expects the transactions contemplated by the Quantenna Agreement to close in the second half of 2019. Factors such as the adoption of the Quantenna Agreement by the requisite vote of Quantenna’s stockholders and the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the applicable antitrust laws of certain other jurisdictions may affect when and whether the merger will occur.

Note 2:    Revenue and Segment Information

The Company is organized into three operating and reporting segments consisting of PSG, ASG and ISG. Because many products are sold into differentend-markets, the total revenue reported for a segment is not indicative of actual sales in theend-market associated with that segment, but rather is the sum of the revenue from the product lines assigned to that segment. These segments represent the Company’s view of the business and as such are used to evaluate progress of major initiatives and allocation of resources.

Revenue and gross profit for the Company’s operating and reporting segments were as follows (in millions):

	PSG		ASG		ISG		Total
For the quarter ended March 29, 2019:
Revenue from external customers	$	704.2	$	494.1	$	188.3	$	1,386.6
Gross profit	$	249.0	$	200.1	$	74.9	$	524.0
For the quarter ended March 30, 2018:
Revenue from external customers	$	692.6	$	496.2	$	188.8	$	1,377.6
Gross profit	$	239.2	$	206.8	$	81.7	$	527.7

Gross profit is exclusive of the amortization of acquisition-related intangible assets. Depreciation expense is included in segment gross profit. Reconciliations of segment gross profit to consolidated gross profit are as follows (in millions):

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’s consolidated assets are not specifically ascribed to its individual reporting segments. Rather, assets used in operations are generally shared across the Company’s operating and reporting segments.

Property, plant and equipment, net by geographic location, is summarized as follows (in millions):

Note 3: Recent Accounting Pronouncements

ASU Adopted:

ASU No.2016-02 - Leases (Topic 842) (“ASU2016-02”), ASU No.2018-10 - Codification improvements to Topic 842, Leases (“ASU2018-10”), ASU No.2018-11 - Leases (Topic 842) (“ASU2018-11”) (collectively, the “New Leasing Standard”)

In February 2016, the FASB issued ASU2016-02, which amended the accounting treatment for leases. ASU 2016-02 requires that a lessee should recognize on its balance sheet a liability to make lease payments (the lease liability) and aright-of-use asset representing its right to use the underlying asset for the lease term. Lessees must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. In July 2018, the FASB issued ASU2018-10 and ASU2018-11. ASU2018-10 provides certain areas for improvement in ASU2016-02 and ASU2018-11 provides an additional optional transition method by allowing entities to initially apply the New Leasing Standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption (the “effective date method”). The New Leasing Standard is effective 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 recordingright-of-use assets of $112.3 million, net of deferred rent liabilities of $5.1 million that were reclassified toright-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. See Note 6: ‘‘Balance Sheet Information’’ for further information and disclosures relating to the New Leasing Standard.

There was no change in the balance of goodwill between December 31, 2018 and March 29, 2019.

Goodwill is tested for impairment annually on the first day of the fourth quarter or more frequently if events or changes in circumstances (each, a “triggering event”) would more likely than not reduce the carrying value of goodwill below its fair value. Management did not identify any triggering events during the quarter ended March 29, 2019 that would require an interim impairment analysis.

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 theright-of-use 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. There are certain immaterial finance leases recorded in the Consolidated Balance Sheet. The Company has elected to account for the lease andnon-lease components as a single lease component.

Right-of-use assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. 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’s existing leases do not contain significant restrictive provisions; however, certain leases contain renewal options and provisions for payment of real estate taxes, insurance and maintenance costs by the Company. The lease term includes options to extend the lease when it is reasonably certain that that the option will be exercised. Leases with a term of 12 months or less are not recorded on the Consolidated Balance Sheet. The lease agreements do not contain any residual value guarantees.

The components of lease expense are as follows (in millions):

	Quarter Ended

Operating lease expense	$	8.3
Variable lease expense		1.2
Short-term lease expense		0.7

Note 8: Earnings Per Share and Equity

Earnings Per Share

Calculations of net income per common share attributable to ON Semiconductor are as follows (in millions, except per share data):

	Quarters Ended
	March 29, 2019		March 30, 2018
Net income attributable to ON Semiconductor Corporation	$	114.1	$	139.6
Basic weighted-average common shares outstanding		410.6		425.9
Dilutive effect of share-based awards		3.2		5.7
Dilutive effect of convertible notes		3.9		12.6
Diluted weighted-average common shares outstanding		417.7		444.2
Net income per common share attributable to ON Semiconductor Corporation:
Basic	$	0.28	$	0.33
Diluted	$	0.27	$	0.31

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

To calculate the diluted weighted-average common shares outstanding, the number of incremental shares from the assumed exercise of stock options and assumed issuance of shares relating to RSUs is calculated by applying the treasury stock method. Share-based awards whose impact is considered to be anti-dilutive under the treasury stock method were excluded from the diluted net income per share calculation. The excluded number of anti-dilutive share-based awards was 0.6 million and 0.5 million for the quarters ended March 29, 2019 and March 30, 2018, respectively.

The dilutive impact related to the Company’s 1.00% Notes and 1.625% Notes is 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. During the quarter ended March 29, 2019, the average share price exceeded the conversion price for the 1.00% Notes and the impact of the excess over par value is included in calculating the dilutive effect of the convertible notes.

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 by the Company 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 amount remitted in the quarters ended March 29, 2019 and March 30, 2018 were $26.1 million and $18.8 million, respectively, for which the Company withheld approximately 1.2 million and 0.7 million shares of common stock, respectively, that were underlying the RSUs that vested. None of these shares had been reissued or retired as of March 29, 2019, but may be reissued or retired by the Company at a later date. These repurchases do not count against the Share Repurchase Program.

At March 29, 2019, total unrecognized share-based compensation expense, net of estimated forfeitures, related tonon-vested RSUs with time-based service conditions, market-based and performance-based vesting criteria was $131.0 million, which is expected to be recognized over a weighted-average period of 1.80 years. The total intrinsic value of stock options exercised during the quarter ended March 29, 2019 was $1.1 million. The Company received cash of $0.5 million, during the quarter ended March 29, 2019 from the exercise of stock options. 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 expense is based on awards that are 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 annualizedpre-vesting forfeiture rate for RSUs was estimated to be 5% during the quarters ended March 29, 2019 and March 30, 2018.

Shares Available

As of March 29, 2019 and December 31, 2018, there was an aggregate of 27.0 million and 33.7 million shares of common stock, respectively, available for grant under the Amended and Restated SIP. As of March 29, 2019 and December 31, 2018, there was an aggregate of 6.5 million shares of common stock, respectively, available for issuance under the ESPP.

Stock Options

The number of options outstanding at December 31, 2018 was 0.3 million at a weighted average exercise price of $6.41 per option, of which 0.1 million options were exercised at a weighted average exercise price of $6.18 per option during the quarter ended March 29, 2019. The number of options outstanding at March 29, 2019 was 0.2 million at a weighted average exercise price of $6.49 per option and had an aggregate intrinsic value of $2.9 million.

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 subjectto clean-up activities under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). Motorola and Freescale (acquired by NXP Semiconductors N.V.) have been involved in theclean-up activitiesof on-site solvent contaminated soil and groundwaterand 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’sformer 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. 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 wellslocated on-site and off-site with additional action plans developed to respond in the event certain levels of contamination 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 andclean-up plan at AMIS’s former corporate headquarters in Santa Clara, California. Costs incurred by AMIS include implementation ofthe 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 andclean-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. 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 Environmental Protection Agency (“EPA”) that it has been identified as a “potentially responsible party” (“PRP”) under CERCLA in the Chemetco Superfund matter. Chemetco, a defunct reclamation services supplier that operated in Hartford, Illinois, which 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 siteclean-up activities. The Company has joined a PRP group, which is cooperating with the EPA in the evaluation and funding of theclean-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 March 29, 2019, the Revolving Credit Facility included $15.0 million of availability for the issuance of letters of credit. As of March 29, 2019, there were letters of credit in the amount of $1.0 million outstanding under the Revolving Credit Facility, which reduces the Company’s borrowing capacity. As of March 29, 2019, the Company also had outstanding guarantees and letters of credit outside of its Revolving Credit Facility totaling $6.2 million. See Note 1: “Background and Basis of Presentation” and Note 16: “Subsequent Event” for information related to the Company’s commitments and financing contingencies with respect to certain pending acquisitions.

As part of obtaining financing in the ordinary course of business, the Company issued guarantees related to certain of its subsidiaries’ finance lease obligations, equipment financing, lines of credit and real estate mortgages, which totaled $60.5 million as of March 29, 2019.

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 ofincorporation, 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 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 foregoing description of the Indemnification Agreement does not purport to be complete and is qualified in its entirety by reference to the full and complete terms of the Indemnification Agreement, which is filed as Exhibit 10.1 to the Current Report onForm 8-K filed by the Company on February 25, 2016 and is incorporated by reference herein.

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 that 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, deliver 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.

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 intellectual property rights, claims ofalleged 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.

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 and the administrative process at the United States Patent and Trademark Office (the “USPTO”) are inherently uncertain, and the Company cannot guarantee that the outcome of these matters will be favorable to it.

Patent Litigation with Power Integrations, Inc.

There are eight outstanding civil litigation proceedings with Power Integrations, Inc. (“PI”), five of which were pending between PI and various Fairchild entities (including Fairchild Semiconductor International, Inc., Fairchild Semiconductor Corporation, and Fairchild (Taiwan) Corporation, f/k/a System General Corporation (collectively referred to inthis sub-section as “Fairchild”), prior to the acquisition of Fairchild. The Company is vigorously defending the lawsuits filed by PI and believes that it has strong defenses. There are also numerous outstanding administrative proceedings between the parties at the USPTO in which each party is challenging the validity of the other party’s patents.

The outcome of any litigation is inherently uncertain and difficult to predict. Any estimate or statement regarding any reserve or the estimated range of possible losses is made solely in compliance with applicable GAAP requirements and is not a statement or admission that the Company is or should be liable in any amount, or that any arguments, motions or appeals before any Court lack merit or are subject to impeachment. To the contrary, the Company believes that it has significant and meritorious grounds for judgment in its favor with respect to all of the PI cases and that the Company’s appeals or motions currently pending at the district court level will significantly reduce or eliminate all prior adverse jury verdicts. Subject to the foregoing, as of the date of the filing of thisForm 10-Q, the Company estimates its range of possible losses for all PI cases to be between approximately $4.0 million and $20.0 million in the aggregate.

Power Integrations v. Fairchild Semiconductor International, Inc. et al. (October 20, 2004, Delaware, 1:04-cv-01371-LPS): PI filed this lawsuit in 2004 in the U.S. District Court for the District of Delaware against Fairchild, alleging that certain of Fairchild’s pulse width modulation (“PWM”) integrated circuit products infringed U.S. patents owned by PI. The lawsuit sought a permanent injunction as well as money damages for Fairchild’s alleged infringement. In October 2006, a jury returned a willful infringement verdict and assessed damages against Fairchild. Fairchild voluntarily stopped U.S. sales and importation of those products in 2007 and has been offering replacement products since 2006. In December 2008, the judge overseeing the case reduced the jury’s 2006 damages award from $34.0 million to approximately $6.1 million and ordered a new trial on the issue of willfulness. Following the new trial held in June 2009, the court found Fairchild’s infringement to have been willful, and in January 2011 the court awarded PI final damages in the amount of $12.2 million. Fairchild appealed the final damages award, willfulness finding, and other issues to the U.S. Court of Appeals for the Federal Circuit. In March 2013, the Court of Appeals vacated substantially all of the damages award, ruling that there was no basis upon which a reasonable jury could find Fairchild liable for induced infringement. The Court of Appeals also vacated the earlier judgment of willful patent infringement. The full Court of Appeals and the Supreme Court of the United States later denied PI’s request to review the Court of Appeals ruling. The Court of Appeals instructed the lower court to conduct further proceedings to determine damages based on approximately $0.8 million worth of sales and imports of affected products, andto re-assess its finding that the infringement was willful. In December 2017, the lower court reinstated the willfulness finding but stayed resolution of the other outstanding issues, including damages. In June 2018, the Supreme Court of the United States decided WesternGeco LLC v. ION Geophysical Corp., in which the Court determined that certain extraterritorial conduct may be relevant to some United States patent litigation. On October 4, 2018, the lower court issued an order finding that WesternGeco implicitly overruled the Court of Appeals’ 2013 decision in this case and stated that PI would be allowed to seek recovery of worldwide damages in a future retrial on damages. The lower court also, however, certified its October 4, 2018 order for interlocutory review by the Court of Appeals. The Court of Appeals has accepted the interlocutory appeal, and briefing in that appeal is underway.

Power Integrations v. Fairchild Semiconductor International, Inc. et al. (May 23, 2008, Delaware, 1:08-cv-00309-LPS): This lawsuit was initiated by PI in 2008 in the U.S. District Court for the District of Delaware against Fairchild, alleging that certain other PWM products infringed several U.S. patents owned by PI. On October 14, 2008, Fairchild filed a patent infringement lawsuit against PI in the U.S. District Court for the District of Delaware, alleging that certain PI products infringed U.S. patents owned by Fairchild. Each lawsuit included claims for money damages and a request for a permanent injunction. These two lawsuits were consolidated and heard together in a jury trial in April 2012, during which the jury found that PI infringed one of the two U.S. patents owned by Fairchild and upheld the validity of both of the Fairchild patents. In the same verdict, the jury found that Fairchild infringed two of four U.S. patents asserted by PI and that Fairchild had induced its customers to infringe the asserted patents. (The court later ruled that Fairchild infringed one other asserted PI patent that the jury found was not infringed.) The jury also upheld the validity of the asserted PI patents, and the court entered a permanent injunction against Fairchild. Willfulness and damages were not considered in the April 2012 trial but were reserved for subsequent proceedings. Fairchild and PI appealed the liability phase of this litigation to the U.S. Court of Appeals for the Federal Circuit, which heard arguments in July 2016 and issued a decision in December 2016. In the decision, the appeals court vacated the jury’s finding that Fairchild induced infringement of PI’s patents, held that one of PI’s patents was invalid, vacated the permanent injunction against Fairchild, reversed the jury’s finding that PI infringed the Fairchild patent, and remanded the case back to the lower court for further

proceedings consistent with these rulings. A second jury trial was held in this matter fromNovember 5-9, 2018, with the jury finding that Fairchild induced infringement of both remaining PI patents and that Fairchild’s infringement was willful. The jury also awarded PI damages in the amount of $24.3 million. In the parties’ post-trial motions, PI is seeking a trebling of the jury verdict in view of the jury’s willfulnessfinding, pre- and post- judgment interest, and its attorneys’ fees, whereas Fairchild is seeking judgment as a matter of law in its favor, or a new trial, on inducement, willfulness, and damages.

Power Integrations v. Fairchild Semiconductor International Inc. et al. (November 4, 2009, Northern District of California,3:09-cv-05235-MMC): In 2009, PI sued Fairchild in the U.S. District Court for the Northern District of California, alleging that several of Fairchild’s products infringe three of PI’s patents. Fairchild filed counterclaims asserting that PI infringed two Fairchild patents. During the initial trial on this matter in 2014, a jury found that Fairchild willfully infringed two PI patents, awarded PI $105.0 million in damages and found that PI did not infringe any Fairchild patent. In September 2014, the court granted a motion filed by Fairchild that sought to set aside the jury’s determination that it acted willfully, and held that, as a matter of law, Fairchild’s actions were not willful. In November 2014, in response to another post-trial motion filed by Fairchild, the trial court ruled that the jury lacked sufficient evidence on which to base its damages award and, consequently, vacated the $105.0 million verdict and ordered a second trial on damages. The second damages trial was held in December 2015, in which a jury awarded PI $139.8 million in damages. Fairchild filed a number of post-trial motions challenging the second damages verdict, but the court ruled against Fairchild on these motions and awarded PI approximately $7.0 million inpre-judgment interest. Following the court’s rulings on these issues, PI moved the court to reinstate the jury’s willfulness finding and sought enhanced damages and attorneys’ fees. On January 23, 2017, the court reinstated the jury’s willful infringement finding, but denied PI’s motion for enhanced damages and attorneys’ fees in its entirety. The Company appealed the infringement and damages judgments, and in July 2018, the U.S. Court of Appeals for the Federal Circuit affirmed the judgment with respect to infringement of both PI patents but vacated the damages judgment because PI had presented legally insufficient evidence to support its damages claim. The appellate court thus remanded the case back to the lower court for a new trial on damages. In August 2018, PI requested that the Federal Circuit rehear,en banc, the issues of the vacated damages award, but this request was denied in September 2018. In December 2018, PI filed a petition for certiorari in the Supreme Court of the United States for review of the Federal Circuit’s decision, to which the Company responded in January 2019. PI also requested that the Supreme Court of the United States review the Federal Circuit’s vacatur of the damages award, but that request was denied in February 2019. All claims of the two PI patents found to be infringed by Fairchild have since been determined to be unpatentable in several inter partes review administrative proceedings described below. The impact of the USPTO’s unpatentability determinations on the district court judgment is uncertain at this stage of the proceedings.

Fairchild Semiconductor International Inc. et al. v. Power Integrations (May 1, 2012, Delaware, 1:12-cv-00540-LPS): In May 2012, Fairchild sued PI in the U.S. District Court for the District of Delaware, and alleged that various PI products infringe Fairchild’s U.S. patents. PI filed counterclaims of patent infringement against Fairchild, asserting five PI patents. Of those five patents, the court granted Fairchild summary judgment of no infringement on one, and PI voluntarily withdrew a second and was forced to remove a third patent during the trial, which began in May 2015. In that trial, the jury found that PI induced infringement of Fairchild’s patent rights and awarded Fairchild $2.4 million in damages. The same jury found that Fairchild infringed a PI patent and awarded PI damages of $0.1 million. Based on the December 2016 appellate court decision in the litigation filed in Delaware in 2008 (described above), on July 13, 2017, the District Court vacated the jury’s finding that PI infringed Fairchild’s patent. A jury trial was held in November 2018 to resolve several outstanding issues prior to appeal in this case. The jury in that trial found that Fairchild induced infringement of the sole PI patent Fairchild had previously been found to infringe and awarded PI damages in the amount of $0.7 million. In the parties’ post-trial motions, PI isseeking pre- and post-judgment interest and a permanent injunction, whereas Fairchild is seeking judgment as a matter of law in its favor, or a new trial, on inducement and damages.

Power Integrations v. Fairchild Semiconductor International Inc. et al. (October 21, 2015, Northern District of California,3:15-cv-04854 MMC): In 2015, PI filed another complaint for patent infringement against Fairchild in the U.S. District Court for the Northern District of California, alleging Fairchild’s products willfully infringe two PI patents. In the complaint, PI is seeking a

permanent injunction, unspecified damages, a trebling of damages, and an accounting of costs and fees. Fairchild answered and counterclaimed, alleging infringement by PI of four Fairchild patents related to aspects of PI’s products, and also seeking damages and a permanent injunction. The lawsuit is in its earliest stages, and had previously been stayed pending the outcome of the Company’s administrative challenges, which are described below, to the two PI patents asserted against Fairchild. In March 2019, however, the stay was lifted and this case was set for trial in November 2020. PI has also filed administrative challenges to Fairchild’s asserted patents.

Power Integrations v. ON Semiconductor Corporation, and Semiconductor Components Industries, LLC (November 1, 2016, Northern District of California,5:16-cv-06371-BLF and5:17-cv-03189):On August 11, 2016, ON Semiconductor Corporation and SCI LLC (collectively referred to in thissub-section as “ON Semi”) filed a lawsuit against PI in the U.S. District Court for the District of Arizona, alleging that PI infringed six patents and seeking a permanent injunction and money damages for the alleged infringement. The lawsuit also sought a claim for a declaratory judgment that ON Semi does not infringe several of PI’s patents. Rather than responding to ON Semi’s lawsuit in Arizona, PI filed a separate lawsuit in the U.S. District Court for the Northern District of California in November 2016, alleging that ON Semi infringes six PI patents, including two of the three PI patents in ON Semi’s declaratory judgment claims from Arizona. PI also moved the Arizona court to dismiss ON Semi’s lawsuit, or in the alternative to transfer the lawsuit to California. Following various procedural motions, ON Semi’s Arizona action has been transferred to the U.S. District Court for the Northern District of California and consolidated with PI’s November 2016 lawsuit, in which PI has subsequently asserted a claim for infringement on the last of the three PI patents in ON Semi’s original declaratory judgment claims. In late 2018, the parties received a claim construction order, which included a finding that claims from several of PI’s asserted patents are invalid. Fact discovery is nearly complete and will be followed by infringement, validity, and damages expert discovery and summary judgment motions. The trial is scheduled for December 2019.

ON Semiconductor Corporation and Semiconductor Components Industries, LLC v. Power Integrations, Inc. (March 9, 2017, District of Delaware,1:17-cv-00247-LPS-CJB): On March 9, 2017, ON Semi filed a lawsuit against PI in the U.S. District Court for the District of Delaware, alleging that PI’s InnoSwitch family of products infringe six of ON Semi’s U.S. patents. Following some procedural motions, PI has since counterclaimed alleging infringement by ON Semi of seven of PI’s U.S. patents. One of those seven patents was dropped by PI because it is asserted against ON Semi in a separate litigation. Both parties seek money damages and a permanent injunction. In late 2018, the parties received a claim construction order, following which ON Semi was forced to stipulateto non-infringement of two of ON Semi’s original six patents. In January 2019, PI voluntarily dropped their claims of infringement on two of PI’s patents, leaving each party with four asserted patents. Fact discovery is nearly complete and will be followed by infringement, validity, and damages expert discovery and summary judgment motions. The trial is scheduled for February 2020.

Semiconductor Components Industries, LLC v. Power Integrations, Inc. (November 2017, Taiwan Intellectual Property Court,106-Ming-min-bu-Tzu-238): In November 2017, Semiconductor Components Industries, LLC filed a lawsuit against PI in Taiwan, alleging infringement by PI of three of ON Semi’s Taiwanese patents. On April 16, 2019, a first-instance judgment was rendered finding that none of the asserted patents were infringed by PI. The Company disagrees with this first-instance finding and is preparing for a second-instance review by the Taiwanese IP Court.

Administrative Challenges to PI’s Patents:

In addition to the eight court proceedings described above, there are presently numerous inter partes review administrative proceedings between PI and ON Semi/Fairchild. Each of these administrative proceedings seeks to invalidate certain claims asserted in the various court proceedings. For the two proceedings filed by ON Semi involving claims asserted in the case filed in 2009 in the Northern District of California, the USPTO has issued a Final Written Decision finding that all of the claims challenged in those proceedings are unpatentable, and PI filed a notice of appeal for those decisions. The USPTO has also issued Final Written Decisions in seven additional proceedings initiated by ON Semi that have been resolved in ON Semi’s favor. PI’s appeals in all but one of those cases are ongoing, and PI failed to appeal one such Final Written Decision. In six of the proceedings

26

initiated by PI, the USPTO has instituted a review of six ON Semi/Fairchild patents that are being asserted against PI. In two of those six proceedings, the USPTO recently found all of the claims challenged by PI to be unpatentable. In one of those two cases, ON Semi has filed an appeal to challenge the unpatentability finding, but elected to forego an appeal in the other case. With regard to a third instituted proceeding initiated by PI, the USPTO found one challenged patent claim unpatentable over the prior art and two claims patentable. PI is pursuing an appeal for this third administrative proceeding, but ON Semi decided to forego an appeal with respect to the claim that was found unpatentable. With regard to a fourth instituted proceeding initiated by PI, the USPTO recently found some patent claims unpatentable over the prior art and some claims patentable, and the Company is evaluating whether to appeal the unpatentability findings. All of the other administrative proceedings between PI and the Company remain pending or were terminated without institution of an administrative trial by the USPTO.

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, and has been docketed as Acbel Polytech, Inc. v. Fairchild Semiconductor International, Inc. et al, Case #1:13-CV-13046-DJC. On December 10, 2016, the Court issued an order on the Company’s motion for summary judgment dismissing all of Acbel’s claims except for claims alleging breach of implied warranties. A bench trial was held in June 2017. On December 27, 2017, the Court rendered a verdict in favor of the Fairchild defendants on the remaining implied warranty claims. Acbel appealed the Court’s ruling, and on September 11, 2018, the U.S. Court of Appeals for the First Circuit heard arguments in this matter from Fairchild and Acbel.

Intellectual Property Matters

The Company faces risk to 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 intellectual property or other remedies.

Note 12: 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 March 29, 2019 and December 31, 2018, the Company had net outstanding foreign exchange contracts with notional amounts of $181.4 million and $157.3 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.

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 quarters ended March 29, 2019 and March 30, 2018, realized and unrealized foreign currency transactions totaled a loss of $3.1 million and $4.4 million, respectively. The realized and unrealized foreign currency transactions are included in other income and expenses 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 the instrument’s maturity date.

Interest rate risk

The Company uses interest rate swap contracts to mitigate its exposure to interest rate fluctuations. The Company does not use such swap contracts for speculative or trading purposes. These contracts effectively hedge some of the future variable rate LIBOR interest expense to a fixed rate interest expense. The derivative instruments qualified for accounting as a cash flow hedge, and the Company designated it as such. On February 25, 2019, the Company entered into additional interest rate swap agreements for notional amounts totaling $1.0 billion (effective as of December 31, 2019) and $750.0 million (effective as of December 31, 2020) with expiry dates of December 31, 2020 and December 31, 2021, respectively. The notional amounts of the interest rate swap agreements outstanding as of March 29, 2019 and March 30, 2018 amounted to $1.0 billion and $750.0 million, respectively. The Company performed effectiveness assessments and concluded that there was no ineffectiveness during the quarters ended March 29, 2019 and March 30, 2018.

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.

For the quarters ended March 29, 2019 and March 30, 2018, the Company did not have outstanding derivatives for its foreign currency exposure designated as cash flow hedges.

Convertible Note Hedges

The Company entered into convertible note hedges in connection with the issuance of the 1.00% Notes and 1.625% Notes.

Other

At March 29, 2019, 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 March 29, 2019, 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.

Note 13: Income Taxes

The Company determines its interim income tax provision by applying the estimated effective income tax rate expected to be applicable for the full fiscal year to the income before income taxes for the period. In determining the full year estimate, the Company does not include the estimated impact of unusual and/or infrequent items, which may cause significant variations in the customary relationship between income tax expense and income before income taxes. Significant judgment is exercised in determining the income tax provision due to transactions, credits and calculations where the ultimate tax determination is uncertain.

The Company’s effective tax rate for the quarter ended March 29, 2019 was 25.1%, which differs from the U.S. federal income tax rate of 21.0%, primarily due to foreign taxes for which the Company will not receive a U.S. tax credit.

The Company recognizes interest and penalties related to unrecognized tax benefits in tax expense on the Company’s Consolidated Statements of Operations and Comprehensive Income. The Company had approximately $5.8 million and $6.4 million of net interest and penalties accrued at March 29, 2019 and March 30, 2018, respectively.

Although the Company cannot predict the timing of resolution with taxing authorities, if any, it believes it is reasonably possible that $7.7 million of its unrecognized tax benefits will be reduced in the next 12 months due to settlement with tax authorities or expiration of the applicable statute of limitations.

Tax years prior to 2015 are generally not subject to examination by the Internal Revenue Service (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 not currently under IRS examination. For state tax returns, the Company is generally not subject to income tax examinations for tax years prior to 2014. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. With respect to major jurisdictions outside the United States, the Company’s subsidiaries are no longer subject to income tax audits for tax years prior to 2008. The Company is currently under audit in the following significant jurisdictions: China, the Czech Republic, Japan, Mauritius and the Philippines.

Executive Overview

Industry Overview

We participate in unit and revenue surveys and use data summarized by WSTS (an industry research firm) to evaluate overall semiconductor market trends and to track our progress against the market in the areas we provide semiconductor components.

32

The most recently published estimates from WSTS project a compound annual growth rate in our serviceable addressable market of approximately 4.0% through 2021. These are not our projections and may not be indicative of actual results. We, like many of our competitors, view this information as helpful third party projections and estimates.

ON Semiconductor Overview

ON Semiconductor is driving innovation in energy-efficient electronics. Our extensive portfolio of sensors, power management, connectivity, custom and SoC, analog, logic, timing and discrete devices helps customers efficiently solve their design challenges in advanced electronic systems and products. Our power management and motor driver semiconductor components control, convert, protect and monitor the supply of power to the different elements within a wide variety of electronic devices. Our custom ASICs and SoC devices use analog, MCU, DSP, mixed-signal and advanced logic capabilities to enable the application and uses of many of our automotive, medical, aerospace/defense, consumer and industrial customers’ products. Our signal management semiconductor components provide high-performance clock management and data flow management for precision computing, communications and industrial systems. Our growing portfolio of sensors, including image sensors, radar and LiDAR, provide advanced solutions for automotive, industrial and IoT applications. Our standard semiconductor components serve as “building blocks” within virtually all types of electronic devices. These various products fall into the logic, analog, discrete, image sensors, IoT and memory categories used by the WSTS group.

We serve a broad baseof end-user markets, including automotive, communications, computing, consumer, medical, industrial, networking, telecom and aerospace/defense. Our devices are found in a wide variety of end products, including automobiles, smartphones, data center and enterprise servers, wearable medical devices, personal computers, industrial building and home automation systems, factory automation, consumer white goods, security and surveillance systems, machine vision and robotics, LED lighting, power supplies, networking and telecom equipment, medical diagnostics and imaging and hearing health.

Our portfolio of devices enables us to offer advanced ICs and the “building block” components that deliver system level functionality and design solutions. We shipped approximately 16.3 billion units during the quarter ended March 29, 2019, as compared to 17.6 billion units during the quarter ended March 30, 2018. We offer micro packages, which provide increased performance characteristics while reducing the critical board space inside today’s ever shrinking electronic devices and power modules, delivering improved energy efficiency and reliability for a wide variety of medium and high power applications. We believe that our ability to offer a broad range of products, combined with our applications and global manufacturing and logistics network, provides our customers with single source purchasing on a cost-effective and timely basis.

Operating and Reporting Segments

As many products are sold into differentend-markets, the total revenue reported for a segment is not indicative of actual sales in theend-market associated with that segment, but rather is the sum of the revenue from the product lines assigned to that segment. From time to time, we reassess the alignment of our product families and devices to our operating segments and may move product families or individual devices from one operating segment to another. As of March 29, 2019, we were organized into the following three operating and reporting segments: PSG, ASG and ISG.

Business and Macroeconomic Environment

The semiconductor industry has traditionally been highly cyclical, has often experienced significant downturns in connection with, or in anticipation of, declines in general economic conditions, and may experience significant uncertainty and volatility in the future. We believe our business today is driven more by secular growth drivers and not solely by macroeconomic and industry cyclicality, as was the case historically. However, in the future, we could again experienceperiod-to-period fluctuations in operating results due to general industry or economic conditions.

We have historically pursued, and expect to continue to pursue, cost-saving initiatives to align our overall cost structure, capital investments and other expenditures with our expected revenue, spending and capacity levels based on our current sales and manufacturing projections. We have recognized efficiencies from previously implemented restructuring activities and programs

33

and continue to implement profitability enhancement programs to improve our cost structure. We have historically taken significant actions to align our overall cost structure with our expectations of market conditions by focusing on synergies-related cost reductions arising from each of our acquisitions. However, there can be no assurances that we will adequately forecast economic conditions or that we will effectively align our cost structure, capital investments and other expenditures with our revenue, spending and capacity levels in the future.

Recent Developments

Quantenna Communications, Inc.

On March 27, 2019, we entered into the Quantenna Agreement with each of Quantenna and Raptor. The Quantenna Agreement provides for the proposed merger of Quantenna with Raptor, whereby Quantenna will continue as the surviving corporation and our wholly-owned subsidiary. See Note 1: “Background and Basis of Presentation” for further information about the Quantenna Agreement.

GLOBALFOUNDRIES U.S. Inc.

On April 22, 2019, we entered into the Asset Purchase Agreement with GFUS and GLOBALFOUNDRIES Inc. pursuant to which we will acquire the Transferred Assets from GFUS. We anticipate that the Asset Purchase will: (i) significantly enhance our access to intellectual property through the licenses; (ii) add a major production facility to our portfolio; (iii) provide us with experienced 300mm wafer manufacturing capabilities and a development team to enable the conversion of our wafer processes from 200mm to 300mm; (iv) provide access to advanced CMOS capability, including 45nm and 65nm technology nodes, which will facilitate our future development; and (v) improve our manufacturing cost structure. See Note 16: ‘‘Subsequent Event’’ for further information about the Asset Purchase Agreement.

Gross profit as a percentage of revenue decreased to approximately 37.0% for the quarter ended March 29, 2019 from approximately 37.6% for the quarter ended March 30, 2018. The decrease was primarily due to product mix.

36

Operating Expenses

Research and development expenses were $151.8 million for the quarter ended March 29, 2019, as compared to $155.2 million for the quarter ended March 30, 2018, representing a decrease of $3.4 million, or approximately 2%. The decrease did not relate to a change in any significant expense driver.

Selling and marketing expenses were $77.1 million for the quarter ended March 29, 2019, as compared to $77.8 million for the quarter ended March 30, 2018, representing a decrease of $0.7 million, or approximately 1%. The decrease did not relate to a change in any significant expense driver.

General and administrative expenses were $72.9 million for the quarter ended March 29, 2019, as compared to $70.9 million in the quarter ended March 30, 2018, representing an increase of $2.0 million, or approximately 3%. The increase did not relate to a change in any significant expense driver.

Other Operating Expenses

Amortization of Acquisition-Related Intangible Assets

Amortization of acquisition-related intangible assets was $25.7 million and $27.4 million for the quarters ended March 29, 2019 and March 30, 2018, respectively, representing a period-over-period decrease of $1.7 million, or approximately 6%. The decrease is primarily as a result of the fewer number of days in the quarter ended March 29, 2019 compared to the quarter ended March 30, 2018.

Restructuring, Asset Impairments and Other, Net

Restructuring, asset impairments and other, net was $5.6 million for the quarter ended March 29, 2019, as compared to $0.4 million for the quarter ended March 30, 2018, representing an increase of $5.2 million, which was attributable to certain restructuring actions approved and undertaken by us during the first quarter of 2019 aimed at cost savings, primarily through workforce reductions. We notified approximately 100 employees of their employment termination, of which 27 had exited by March 29, 2019. The expense for this program amounted to $5.5 million, of which $4.3 million remains accrued as of March 29, 2019. We will continue to evaluate positions for redundancies and may incur additional charges in the future.

Intangible Asset Impairment

Intangible asset impairment was $1.2 million for the quarter ended March 29, 2019, as compared to zero for the quarter ended March 30, 2018. During the quarter ended March 29, 2019, we abandoned one of our previously capitalized IPRD projects and recorded an impairment charge of $1.2 million.

Interest Expense

Interest expense increased by $0.2 million to $31.7 million during the quarter ended March 29, 2019, as compared to $31.5 million during the quarter ended March 30, 2018 primarily due to an increase in interest rates offset by repayments of outstanding balances. Our average gross long-term debt balance (including current maturities) for the quarter ended March 29, 2019 was $2,935.0 million at a weighted-average interest rate of approximately 4.3%, as compared to $3,109.2 million at a weighted-average interest rate of approximately 4.1% for the quarter ended March 30, 2018.

Licensing Income

Licensing income was zero for the quarter ended March 29, 2019, as compared to $3.8 million for the quarter ended March 30, 2018. The licensing income during the quarter ended March 30, 2018 was attributable to payments received under various licensing agreements.

37

Other Income (Expense)

Other income (expense) increased by $4.1 million to income of $2.1 million for the quarter ended March 29, 2019, compared to an expense of $2.0 million for the quarter ended March 30, 2018. The increase is primarily attributable to the $4.9 million indemnification gain on the resolution of a foreign tax dispute.

Provision for Income Taxes

We recorded an income tax provision of $38.2 million and $16.4 million during the quarters ended March 29, 2019 and March 30, 2018, respectively.

The income tax provision for the quarter ended March 29, 2019 consisted of $36.0 million for income and withholding taxes of certain of our foreign and domestic operations, $6.0 million relating to the resolution of a foreign tax dispute, $0.9 million primarily related to new interest and penalties on existing reserves for unrecognized tax benefits and $0.4 million of prior year adjustments, offset by a discrete benefit of $5.1 million relating to equity award excess tax benefits.

The income tax provision for the quarter ended March 30, 2018 consisted of $39.9 million for income and withholding taxes of certain of our foreign and domestic operations and $0.3 million of new interest on existing reserves for uncertain tax positions in foreign tax jurisdictions, offset by discrete benefits of $17.1 million relating to an increase in deferred tax assets expected to be realized in the foreseeable future due to the liquidation of a foreign subsidiary and $6.7 million relating to equity award excess tax benefits.

We expect our effective tax rate, before discrete items, to be between 22% and 26% until we fully utilize all of our U.S. federal net operating losses. The primary difference between our effective tax rate and the federal statutory rate of 21% is due to foreign taxes for which the Company will not receive a U.S. tax credit until our U.S. federal net operating losses are fully utilized. Once our U.S. federal net operating losses are fully utilized, we expect our future effective tax rate, before discrete items, to approximate, or be lower than, the federal statutory rate of 21%. We anticipate our U.S. federal net operating losses and credits will be fully utilized by 2021.

Our cash tax, as a percentage of income before income taxes (“Cash Tax Rate”), is significantly lower than our effective tax rate due to the current utilization of our U.S. federal net operating losses and credits. We expect our future Cash Tax Rate to approximate our effective tax rate once our U.S. federal net operating losses and credits are fully utilized.

We continue to maintain a full valuation allowance on our U.S. state deferred tax assets and a valuation allowance on foreign net operating losses and tax credits in certain other foreign jurisdictions, a substantial portion of which relate to Japan net operating losses which are projected to expire prior to utilization.

This section includes a discussion and analysis of our cash requirements,off-balance sheet arrangements, contingencies, sources and uses of cash, operations, working capital and long-term assets and liabilities.

Contractual Obligations

As of March 29, 2019, there were no material changes outside of the ordinary course of business to the contractual obligations table, including the notes thereto, contained in the 2018 Form10-K. See Note 6: ‘‘Balance Sheet Information’’ for information with respect to operating leases and pension plan, in each case, in the notes to our unaudited consolidated financial statements included elsewhere in this Form10-Q.

38

Our balance of cash and cash equivalents was $939.6 million as of March 29, 2019. We believe that our cash flows from operations, coupled with our existing cash and cash equivalents, and cash available from our Revolving Credit Facility, will be adequate to fund our operating and capital needs for at least the next 12 months, including the capital requirements associated with the Quantenna Agreement and the Asset Purchase Agreement. Total cash and cash equivalents as of March 29, 2019 include approximately $317.9 million available within the United States. While we hold a significant amount of cash and cash equivalents outside the United States in various foreign subsidiaries, we have the ability to obtain cash in the United States in order to cover our domestic needs, through distributions from our foreign subsidiaries, by utilizing existing credit facilities or through new bank loans or debt obligations.

Off-Balance Sheet Arrangements

In the ordinary course of business, we provide standby letters of credit or other guarantee instruments to certain parties in connection with certain transactions, including, but not limited to: material purchase commitments, agreements to mitigate collection risk, leases, utilities or customs guarantees. As of March 29, 2019, our Revolving Credit Facility included $15.0 million of availability for the issuance of letters of credit. There were letters of credit in the amount of $1.0 million outstanding under our Revolving Credit Facility as of March 29, 2019, which reduces our borrowing capacitydollar-for-dollar. As of March 29, 2019, we also had outstanding guarantees and letters of credit outside of our Revolving Credit Facility in the amount of $6.2 million.

As part of securing financing in the ordinary course of business, we have issued guarantees related to certain of our subsidiaries’ finance lease obligations, equipment financing, lines of credit and real estate mortgages which totaled $60.5 million as of March 29, 2019. Based on historical experience and information currently available, we believe that we will not be required to make payments under the standby letters of credit or guarantee arrangements for the foreseeable future.

We have not recorded any liability in connection with these letters of credit and guarantee arrangements. See Note 3: ‘‘Recent Accounting Pronouncements,’’ Note 7: ‘‘Long-Term Debt’’ and Note 10: ‘‘Commitments and Contingencies’’ in the notes to our unaudited consolidated financial statements included elsewhere in this Form10-Q for additional information.

Contingencies

We are a party to a variety of agreements entered into in the ordinary course of business pursuant to which we may be obligated to indemnify 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 us require us to indemnify the other party against losses due to IP infringement, environmental contamination and other property damage, personal injury, our failure to comply with applicable laws, our negligence or willful misconduct or our breach of representations, warranties or covenants related to such matters as title to sold assets.

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

We maintain directors’ and officers’ insurance policies that indemnify our directors and officers against various liabilities, including certain liabilities under the Exchange Act, that might be incurred by any director or officer in his or her capacity as such.

The Fairchild Agreement provides for indemnification and insurance rights in favor of Fairchild’s then current and former directors, officers and employees. Specifically, we have agreed that, for no fewer than six years following the Fairchild acquisition, we 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

39

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.

While our 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 our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under any of these indemnities have not had a material effect on our business, financial condition, results of operations or cash flows, and we do not believe that any amounts that we may be required to pay under these indemnities in the future will be material to our business, financial condition, results of operations or cash flows.

See Note 10: ‘‘Commitments and Contingencies’’ in the notes to our unaudited consolidated financial statements under the heading “Legal Matters” included elsewhere in this Form10-Q for possible contingencies related to legal matters. See also Part I, Item 1 “Business—Government Regulation” of the 2018 Form10-K for information on certain environmental matters.

Sources and Uses of Cash

We require cash to fund our operating expenses and working capital requirements, including outlays for strategic acquisitions and investments, for research and development, to make capital expenditures, to repurchase our common stock and other Company securities and to pay debt service, including principal and interest and finance lease payments. We expect interest expense to remain significant in future periods as we continue to service our debt. Our principal sources of liquidity are cash on hand, cash generated from operations and funds from external borrowings and equity issuances. In the near term, we expect to fund our primary cash requirements through cash generated from operations and with cash and cash equivalents on hand. We also have the ability to utilize our Revolving Credit Facility.

As part of our business strategy, we review acquisition and divestiture opportunities and proposals on a regular basis. During the quarter ended March 29, 2019 we entered into a definitive agreement to acquire Quantenna, which is expected to close in the second half of 2019. See Note 1: ‘‘Background and Basis of Presentation’’ in the notes to our unaudited consolidated financial statements for additional information.

We believe that the key factors that could affect our internal and external sources of cash include:

• Factors that affect our results of operations and cash flows, including the impact on our business and operations as a result of changes in demand for our products, competitive pricing pressures, effective management of our manufacturing capacity, our ability to achieve further reductions in operating expenses, the impact of our restructuring programs on our production and cost efficiency and our ability to make the research and development expenditures required to remain competitive in our business; and

• Factors that affect our access to bank financing and the debt and equity capital markets that could impair our ability to obtain needed financing on acceptable terms or to respond to business opportunities and developments as they arise, including interest rate fluctuations, macroeconomic conditions, sudden reductions in the general availability of lending from banks or the related increase in cost to obtain bank financing and our ability to maintain compliance with covenants under our debt agreements in effect from time to time.

Our ability to service our long-term debt, including our 1.625% Notes, 1.00% Notes, Revolving Credit Facility and Term Loan “B” Facility, to remain in compliance with the various covenants contained in our debt agreements and to fund working capital, capital expenditures and business development efforts will depend on our ability to generate cash from operating activities, which is subject to, among other things, our future operating performance, as well as to general economic, financial, competitive, legislative, regulatory and other conditions, some of which may be beyond our control.

40

If we fail to generate sufficient cash from operations, we may need to raise additional equity or borrow additional funds to achieve our longer term objectives. There can be no assurance that such equity or borrowings will be available or, if available, will be at rates or prices acceptable to us. We believe that cash flow from operating activities coupled with existing cash and cash equivalents and existing credit facilities will be adequate to fund our operating and capital needs, as well as enable us to maintain compliance with our various debt agreements, through at least the next 12 months. To the extent that results or events differ from our financial projections or business plans, our liquidity may be adversely impacted.

During the ordinary course of business, we evaluate our cash requirements and, if necessary, adjust our expenditures for inventory, operating expenditures and capital expenditures to reflect the current market conditions and our projected sales and demand. Our capital expenditures are primarily directed toward production equipment and capacity expansion. Our capital expenditure levels can materially influence our available cash for other initiatives. For example, during the quarter ended March 29, 2019, we paid $157.0 million for capital expenditures, while during the quarter ended March 30, 2018, we paid $99.5 million for capital expenditures. Our current minimum contractual capital expenditure commitment for the remainder of 2019 is approximately $108.7 million. Our current minimum contractual capital expenditure commitment for 2020 and thereafter is approximately $3.9 million. We expect to incur capital expenditures of approximately 8% to 9% of annual revenue for the remainder of 2019 and 2020 to adjust to a higher growth environment and to further improve our manufacturing cost structure. Future capital expenditures may be impacted by events and transactions that are not currently forecasted.

Primary Cash Flow Sources

Our long-term cash generation is dependent on the ability of our operations to generate cash. Our cash flows from operating activities were $138.2 million and $226.5 million for the quarter ended March 29, 2019 and March 30, 2018, respectively. The decrease of $88.3 million was primarily attributable to the change in working capital during the period. Our ability to maintain positive operating cash flows is dependent on, among other factors, our success in achieving our revenue goals and manufacturing and operating cost targets.

Our management of our assets and liabilities, including both working capital and long-term assets and liabilities, also influences our operating cash flows, and each of these components is discussed below.

Working Capital

Working capital, calculated as total current assets less total current liabilities, fluctuates depending onend-market demand and our effective management of certain items such as receivables, inventory and payables. In times of escalating demand, our working capital requirements may be affected as we purchase additional manufacturing materials and increase production. Our working capital may also be affected by restructuring programs, which may require us to use cash for severance payments, asset transfers and contract termination costs. In addition, our working capital may be affected by acquisitions and transactions involving our convertible notes and other debt instruments. Our working capital, excluding cash and cash equivalents and the current portion of long-term debt, was $920.4 million at March 29, 2019 and has fluctuated between $930.5 million and $743.4 million at the end of each of our last eight fiscal quarters. Our working capital, including cash and cash equivalents and the current portion of long-term debt, was $1,729.2 million at March 29, 2019 and has fluctuated between $1,782.3 million and $1,022.0 million at the end of each of our last eight fiscal quarters.

Although investments made to fund working capital will reduce our cash balances, these investments are necessary to support business and operating initiatives. During the quarter ended March 29, 2019, our working capital was most significantly impacted by payments for variable compensation and our capital expenditures.

Long-Term Assets and Liabilities

Our long-term assets consist primarily of property, plant and equipment, intangible assets, deferred taxes and goodwill.

41

Our manufacturing rationalization plans have included efforts to utilize our existing manufacturing assets and supply arrangements more efficiently. We believe that near-term access to additional manufacturing capacity, should it be required, could be readily obtained on reasonable terms through manufacturing agreements with third parties. We will continue to look for opportunities to make strategic purchases in the future for additional capacity.

Our long-term liabilities, excluding long-term debt and deferred taxes, consist of liabilities under our foreign defined benefit pension plans and contingent tax reserves. In regard to our foreign defined benefit pension plans, our annual funding of these obligations is equal to the minimum amount legally required in each jurisdiction in which the plans operate. This annual amount is dependent upon numerous actuarial assumptions. For additional information, see Note 6: ‘‘Balance Sheet Information’’ and Note 13: ‘‘Income Taxes’’ in the notes to our unaudited consolidated financial statements included elsewhere in this Form10-Q.

Key Financing and Capital Events

Overview

For the past several years, we have undertaken various measures to secure liquidity to pursue acquisitions, repurchase shares of our common stock, reduce interest costs, amend existing key financing arrangements and, in some cases, extend a portion of our debt maturities to continue to provide us additional operating flexibility.

Cash Management

Our ability to manage cash is limited, as our primary cash inflows and outflows are dictated by the terms of our sales and supply agreements, contractual obligations, debt instruments and legal and regulatory requirements. While we have some flexibility with respect to the timing of capital equipment purchases, we must invest in capital equipment on a timely basis to allow us to maintain our manufacturing efficiency and support our platforms for new products.

Debt Guarantees and Related Covenants

As of March 29, 2019, we were in compliance with the indentures relating to our 1.00% Notes and 1.625% Notes and with covenants in the Amended Credit Agreement, including those relating to our Term Loan “B” Facility and Revolving Credit Facility, and covenants in our other debt agreements. Our 1.00% Notes are senior to the existing and future subordinated indebtedness of ON Semiconductor and its guarantor subsidiaries. Our 1.625% Notes rank equally in right of payment to all of our existing and future senior debt and as unsecured obligations are subordinated to all of our existing and future secured debt. See Note 7: ‘‘Long-Term Debt’’ in the notes to our unaudited consolidated financial statements included elsewhere in this Form10-Q for additional information.

Recent Accounting Pronouncements

For a discussion of recent accounting pronouncements, see Note 3: ‘‘Recent Accounting Pronouncements’’ in the notes to our unaudited consolidated financial statements included elsewhere in this Form10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial market risks, including changes in interest rates and foreign currency exchange rates. To mitigate these risks, we utilize derivative financial instruments. We do not use derivative financial instruments for speculative or trading purposes.

As of March 29, 2019, our long-term debt (including current maturities) totaled $2,931.1 million. We have no interest rate exposure to rate changes on our fixed rate debt, which totaled $2,294.0 million as of March 29, 2019. We do have interest rate exposure with respect to the $637.1 million balance of our variable interest rate debt outstanding as of March 29, 2019. A 50 basis point increase in interest rates, including the impact of interest rate swaps, would impact our expected annual interest

42

expense for the next 12 months by approximately $3.2 million. However, some of this impact would be offset by additional interest earned on our cash and cash equivalents should rates on deposits and investments also increase. We entered into interest rate swaps to hedge some of the risk of variability in cash flows resulting from future interest payments on our variable interest rate debt under the Term Loan “B” Facility.

Except as described above, our exposure to market risk from December 31, 2018 to March 29, 2019 has not changed materially from the information provided in the 2018 Form10-K.

To ensure the adequacy and effectiveness of our foreign exchange hedge positions, we continually monitor our foreign exchange forward positions, both on a stand-alone basis and in conjunction with their underlying foreign currency exposures, from an accounting and economic perspective. However, given the inherent limitations of forecasting and the anticipatory nature of exposures intended to be hedged, we cannot provide any assurances that such programs will offset more than a portion of the adverse financial impact resulting from unfavorable movements in foreign exchange rates.

We are subject to risks associated with transactions that are denominated in currencies other than our functional currencies, as well as the effects of translating amounts denominated in a foreign currency to the U.S. Dollar as a normal part of the reporting process. Some of our Japanese operations utilize Japanese Yen as the functional currency, which results in a translation adjustment that is included as a component of accumulated other comprehensive income.

We enter into forward foreign currency contracts that economically hedge the gains and losses generated by there-measurement of certain recorded assets and liabilities in anon-functional currency. Changes in the fair value of these undesignated hedges are recognized in other income and expense immediately as an offset to the changes in the fair value of the assets or liabilities being hedged. The notional amount of foreign exchange contracts at March 29, 2019 and December 31, 2018 was $181.4 million and $157.3 million, respectively. Our policies prohibit speculation on financial instruments, trading in currencies for which there are no underlying exposures or entering into trades for any currency to intentionally increase the underlying exposure.

Substantially all of our revenue is transacted in U.S. Dollars. However, a significant amount of our operating expenditures and capital purchases are transacted in local currencies, including Japanese Yen, Euros, Korean Won, Malaysian Ringgit, Philippines Peso, Singapore Dollars, Swiss Francs, Chinese Renminbi and Czech Koruna. Due to the materiality of our transactions in these local currencies, our results are impacted by changes in currency exchange rates measured against the U.S. Dollar. For example, we determined that based on a hypothetical weighted-average change of 10% in currency exchange rates, our results would have impacted our income before taxes by approximately $25.0 million as of March 29, 2019, assuming no offsetting hedge positions or correlated activities.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules13a-15(e) and15d-15(e) of the Exchange Act). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered in this report, our disclosure controls and procedures were effective to ensure that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within the required time periods and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

We also carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of changes to our internal control over financial reporting (as defined in Rules13a-15(f) and15d-15(f) of the Exchange Act) that occurred during the fiscal quarter ended March 29, 2019.

There have been no changes to our internal control over financial reporting (as defined in Exchange Act Rules13a-15(f) and15d-15(f)) that occurred during the fiscal quarter ended March 29, 2019 which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(1) These time periods represent our fiscal month start and end dates for the first quarter of 2019.

(2) The number of shares purchased represents shares of common stock held by employees who tendered owned shares of common stock to the Company to satisfy the employee withholding taxes due upon the vesting of RSUs and shares purchased under the Share Repurchase Program.

(3) The price per share is based on the fair market value at the time of tender or repurchase, respectively.

Share Repurchase Program

During the quarter ended March 29, 2019, we repurchased 4.4 million shares of our common stock for $75.7 million under the Share Repurchase Program.

Under the Share Repurchase Program, we may repurchase up to $1.5 billion (exclusive of fees, commissions and other expenses) of our common stock over a period of four years from December 1, 2018, subject to certain contingencies. We may repurchase our common stock from time to time in privately negotiated transactions or open market transactions, including pursuant to a trading plan in accordance with Rule10b5-1 and Rule10b-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 our stock price, corporate and regulatory requirements, restrictions under our debt obligations, the availability of capital and other market and economic conditions. The Share Repurchase Program does not require us to purchase any particular amount of common stock and is subject to a variety of factors including the discretion of our board of directors. As of March 29, 2019, the authorized amount remaining under the Share Repurchase Program was $1,424.3 million.

See Note 8: ‘‘Earnings Per Share and Equity’’ of the notes to our unaudited consolidated financial statements included elsewhere in this Form10-Q for further information on shares of common stock tendered to the Company by employees to satisfy applicable employee withholding taxes due upon vesting of RSUs and the Share Repurchase Program.
