NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1: Background and Basis of Presentation

ON Semiconductor Corporation, together with its wholly and majority-owned subsidiaries (the “Company”), is a global supplier of power and data management semiconductors and standard semiconductor components. The Company was a wholly-owned subsidiary of Motorola Inc. (“Motorola”) prior to its August 4, 1999 recapitalization (the “recapitalization”).

On August 4, 1999, the Company was recapitalized and certain related transactions were effected pursuant to an agreement among ON Semiconductor Corporation, its principal domestic operating subsidiary, Semiconductor Components Industries, LLC (“SCI LLC”), Motorola and affiliates of Texas Pacific Group (“TPG”). Because TPG did not acquire substantially all of the Company’s common stock, the basis of the Company’s assets and liabilities for financial reporting purposes was not impacted by the recapitalization.

The accompanying unaudited financial statements as of March 30, 2007, and for the quarter ended March 30, 2007 and March 31, 2006 respectively, have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for audited financial statements. In the opinion of the Company’s management, the interim information includes all adjustments, consisting only of 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 as of December 31, 2006 and for the year then ended included in the Company’s annual report on Form 10-K for the year ended December 31, 2006.

Note 2: Liquidity

During the quarter ended March 30, 2007, the Company reported net income of $54.0 million compared to $40.4 million for the quarter ended March 31, 2006. Net cash provided by operating activities was $63.1 million for the quarter ended March 30, 2007, as compared to $50.5 million for the quarter ended March 31, 2006.

At March 30, 2007, the Company had $275.8 million in cash and cash equivalents, net working capital of $308.9 million, term and revolving debt of $1,150.4 million in the aggregate and a stockholders’ deficit of $157.2 million. The Company’s long-term debt is due at various times ranging from 2007 to 2026 depending on the debt instrument (see Note 6: Long-Term Debt). The Company’s long-term debt agreements also include various covenants which the Company was in compliance with as of March 30, 2007 and expects to remain in compliance with over the next twelve months.

The Company’s ability to service its long-term debt, to remain in compliance with the various covenants and restrictions contained in its financing agreements and to fund working capital, capital expenditures and business development efforts will depend on its ability to generate cash from operating activities which is subject to, among other things, its future operating performance as well as to general economic, financial, competitive, legislative, regulatory and other conditions, some of which may be beyond its control.

If the Company fails to generate sufficient cash from operations, it may need to sell additional equity or borrow additional funds to achieve its longer term objectives. There can be no assurance that such equity or borrowings will be available or, if available, will be on terms acceptable to the Company. Management believes that cash flows from operating activities coupled with existing cash balances will be adequate to fund the Company’s operating and capital needs through at least March 30, 2008. To the extent that results or events differ from the Company’s financial projections or business plans, its liquidity may be adversely impacted.

Note 3: Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company, as well as its wholly-owned and majority-owned subsidiaries. Investments in companies that represent less than 20% of the related voting stock are accounted for on the cost basis. All intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in accordance with generally accepted accounting principles 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 revenues and expenses during the reporting period. Significant estimates have been used by management in conjunction with the measurement of valuation allowances relating to trade and tax receivables, inventories and deferred tax assets; reserves for customer incentives, warranties, tax reserves and pension obligations; the fair values of stock options and of financial instruments (including derivative financial instruments); and future cash flows associated with long-lived assets. Actual results could differ from these estimates.

Cash and cash equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents are maintained with reputable major financial institutions. Deposits with these banks may exceed the amount of insurance provided on such deposits; however, these deposits typically may be redeemed upon demand and, therefore, bear minimal risk.

Allowance for Doubtful Accounts

In the normal course of business, the Company provides unsecured credit terms to its customers. Accordingly, the Company maintains an allowance for doubtful accounts for possible losses on uncollectible accounts receivable. The Company routinely analyzes accounts receivable and considers history, customer creditworthiness, facts and circumstances specific to outstanding balances, current economic trends, and payment term changes when evaluating adequacy of the allowance for doubtful accounts. For uncollectible accounts receivable the Company records a loss against the allowance for doubtful accounts only after exhaustive efforts have been made to collect and with management’s approval. Generally, realized losses have been within the range of management’s expectations.

Approximately 16% of the Company’s revenues for the quarter ended March 30, 2007, are attributable to its various automotive customers. Certain of these automotive customers have been experiencing a downturn in their business, in part due to labor difficulties. On October 8, 2005, Delphi Corporation (“Delphi”), one of the Company’s automotive customers, and certain of Delphi’s U.S. subsidiaries commenced reorganization proceedings under Chapter 11 of the U.S. Federal Bankruptcy Code. During the quarter ended March 30, 2007, the Company’s revenues from Delphi accounted for less than 3% of its total revenues. During the quarter ended March 30, 2007, the Company sold, without discount, to a third party with recourse to the Company all of its receivables due from Delphi of $5.4 million that are subject to collection pending resolution of the reorganization proceedings.

Inventories

Inventories are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis), or market. The Company records provisions for slow moving inventories based upon a regular analysis of inventory on hand compared to projected end user demand. Projected end user demand is generally based on sales during the prior twelve months. These provisions can influence results from operations. For example, when demand for a given part falls, all or a portion of the related inventory is reserved, impacting cost of revenues and gross profit. If demand recovers and the parts previously reserved are sold, a higher than normal margin will generally be recognized. General market conditions as well as the Company’s design activities can cause certain of its products to become obsolete.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost and are depreciated over estimated useful lives of 30-50 years for buildings and 3-20 years for machinery and equipment using accelerated and straight-line methods. During periods prior to the second quarter of 2006, a majority of the machinery and equipment was depreciated on a straight-line basis over a useful life of 5 years. During the second quarter of 2006, the Company changed the estimated useful life for a majority of its machinery and equipment currently in use from 5 years to 10 years. See Note 4: Accounting Changes for further discussion. Expenditures for maintenance and repairs are charged to operations in the year in which the expense is incurred. When assets are retired or otherwise disposed of, the related costs and accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in operations in the period realized.

The Company evaluates the recoverability of the carrying amount of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. An impairment charge is recognized when the undiscounted expected cash flows derived from an asset are less than its carrying amount. Impairment losses are measured as the amount by which the carrying value of an asset exceeds its fair value and are recognized in operating results. Judgment is used when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of an impaired asset. The dynamic economic environment in which the Company operates and the resulting assumptions used to estimate future cash flows impact the outcome of these impairment tests.

The Company plans to sell approximately 42 acres of land and two buildings located at its corporate headquarters in Phoenix, Arizona. The remainder of the Phoenix site will continue as the Company’s corporate headquarters as well as a manufacturing, design center and research and development facility. During the first quarter of 2007, the Company entered into an agreement to sell approximately 20 acres of the land for approximately $11.5 million subject to certain adjustments. If the sale is completed, at the originally contracted price, the Company expects to record a gain of approximately $10.0 million during the quarter the transaction closes. The remaining property and buildings are currently being marketed for sale with a list price between $10.0 million and $15.0 million.

Goodwill

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the Company’s April 2000 acquisition of Cherry Semiconductor Corporation (Cherry) and in the Company’s September 2006 acquisition of an additional interest in its investment in Leshan-Phoenix Semiconductor Company (“Leshan”). When the Company adopted Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets” (“SFAS No. 142”) the net carrying value of the Cherry Goodwill was $77.3 million, which included $18.4 million of accumulated amortization. Additionally, during the third quarter of 2006 the Company acquired additional interest in its investment in Leshan for $9.2 million, for which the incremental interest in the underlying net tangible assets had an estimated fair value of $5.4 million resulting in $3.8 million of Goodwill. Under SFAS No. 142, goodwill is evaluated for potential impairment on an annual basis or whenever events or circumstances indicate that an impairment may have occurred. SFAS No. 142 requires that goodwill be tested for impairment using a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares the estimated fair value of the reporting unit containing goodwill with the related carrying amount. If the estimated fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step of the impairment test is unnecessary. If the reporting unit’s carrying amount exceeds its estimated fair value, the second step test must be performed to measure the amount of the goodwill impairment loss, if any. The second step test compares the implied fair value of the reporting unit’s goodwill, determined in the same manner as the amount of goodwill recognized in a business combination, with the carrying amount of such goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The Company performs its annual impairment analysis as of the first day of the fourth quarter of each year.

Intangible Assets

Intangible assets consist of values assigned to intellectual property and assembled workforce resulting from the May 2006 purchase by the Company’s principal domestic operating subsidiary, Semiconductor Components Industries, LLC (“SCI LLC”) of LSI Logic Corporation’s (“LSI”) Gresham, Oregon wafer fabrication facility. These are stated at cost less accumulated amortization and are amortized over their economic useful life of 5 years using the straight-line method and are reviewed for impairment when facts or circumstances suggest that the carrying value of these assets may not be recoverable.

Intangible assets, net were as follows as of March 30, 2007 (in millions):


	Original Cost		Accumulated Amortization			Carrying Value		Useful Life (in Years)
Intellectual Property	$	5.2	$	(0.9	)	$	4.3	5
Assembled Workforce	$	6.7		(1.2	)	$	5.5	5

Total intangibles		11.9		(2.1	)		9.8

Amortization expense for intangible assets amounted to $0.6 million for the quarter ended March 30, 2007, and is expected to be as follows over the next five years (in millions).


	Intellectual Property		Assembled Workforce
Remainder of 2007	$	0.8	$	0.9
2008		1.0		1.3
2009		1.0		1.3
2010		1.0		1.3
2011		0.5		0.7

Total estimated amortization expense	$	4.3	$	5.5

Debt Issuance Costs

Debt issuance costs are capitalized and amortized over the term of the underlying agreements using the effective interest method. Upon prepayment of debt, the related unamortized debt issuance costs are charged to expense. Amortization of debt issuance costs is included in interest expense while the unamortized balance is included in other assets. Capitalized debt issuance costs totaled $22.1 million and $22.9 million at March 30, 2007 and December 31, 2006, respectively.

Revenue Recognition

The Company generates product revenue from sales of its semiconductor products to original equipment manufacturers, electronic manufacturing service providers and distributors. The Company also generates revenue, although to a much lesser extent, from manufacturing services provided to customers. The Company recognizes product revenue on sales to original equipment manufacturers and electronic manufacturing service providers when title passes to the end customer net of provisions for related sales returns and allowances. Title to products sold to distributors typically passes at the time of shipment by the Company so the Company records accounts receivable for the amount of the transaction, reduces its inventory for the products shipped and defers the related margin in the consolidated balance sheet. The Company recognizes the related revenue and margin when the distributor informs the Company that it has resold the products to the end user. Although payment terms vary, most distributor agreements require payment within 30 days. Freight and handling costs are included in cost of revenues and are recognized as period expense during the period in which they are incurred. Taxes assessed by governmental authorities on revenue-producing transactions, including value added and excise taxes, are presented on a net basis (excluded from revenues) in the statement of operations.

Research and Development Costs

Research and development costs are expensed as incurred.

Share-Based Payments

In December 2004, the Financial Accounting Standards Board (“FASB”) revised Statement of Financial Accounting Standards No. 123 (“SFAS No. 123R”), “Share-Based Payment,” which establishes accounting for share-based awards exchanged for employee services and requires companies to expense the estimated fair value of these awards over the requisite employee service period. On April 14, 2005, the U.S. Securities and Exchange Commission adopted a new rule amending the effective dates for SFAS 123R. In accordance with the new rule, the Company adopted SFAS No. 123R on January 1, 2006.

Under SFAS 123R, share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee’s requisite service period. As of March 30, 2007, the Company had no unvested awards with market or performance conditions, although it did have outstanding awards with time and service based vesting provisions. The Company adopted the provisions of SFAS No. 123R on January 1, 2006, the first day of the Company’s fiscal year 2006, using a modified prospective application, which provides for certain changes to the method for recognizing share-based compensation. Under the modified prospective application, prior periods are not revised for comparative purposes. The provisions of SFAS No. 123R apply to new awards and to awards that are outstanding with future service periods on the effective date. Estimated compensation expense for awards outstanding with future service periods at the effective date will be recognized over the remaining service period using the compensation cost calculated for pro forma disclosure purposes under FASB Statement No. 123, “Accounting for Stock-Based Compensation”.

Income Taxes

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

In determining the amount of the valuation allowance, estimated future taxable income as well as feasible tax planning strategies in each taxing jurisdiction is considered. If all or a portion of the remaining deferred tax assets will not be realized, the valuation allowance will be increased with a charge to income tax expense. Conversely, if the Company will ultimately be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be released to income as a credit to income tax expense.

The calculation of tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. The Company recognizes potential liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based on its estimate of whether, and the extent to which, additional taxes will be due. If payment of these liabilities ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary. Additionally, the Company reviews the collectibility of its tax receivables due from various jurisdictions and when recovery is uncertain, the Company reserves amounts deemed to be uncollectible. If the receipts of these amounts occur or are assured, the reversal of the reserves previously established would result in a tax benefit in the period.

Foreign Currencies

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

(unaudited)

The Company’s remaining foreign subsidiaries utilize the local currency as their functional currency. The assets and liabilities of these subsidiaries are translated at current exchange rates while revenues and expenses are translated at the average rates in effect for the period. The related translation gains and losses are included in accumulated other comprehensive income within stockholders’ deficit.

Defined Benefit Plans

The Company maintains pension plans covering certain of its foreign employees. For financial reporting purposes, net periodic pension costs are calculated based upon a number of actuarial assumptions, including a discount rate for plan obligations, assumed rate of return on pension plan assets and assumed rate of compensation increases for plan employees. All of these assumptions are based upon management’s judgment and consultation with an actuary, considering all known trends and uncertainties.

Asset Retirement Obligations

The Company recognizes asset retirement obligations (“AROs”) when incurred, with the initial measurement at fair value. These liabilities are accreted to full value over time through charges to income. In addition, asset retirement costs are capitalized as part of the related asset’s carrying value and are depreciated over the asset’s respective useful life. The weighted average discount rate used to determine the liability as of March 30, 2007 was 6.7%. The Company’s AROs consist primarily of estimated decontamination costs associated with manufacturing equipment and buildings resulting from the Company’s adoption of FIN 47, “Accounting for Conditional Asset Retirement Obligations—An Interpretation of FASB Statement No. 143” effective December 31, 2005.

Contingencies

The Company is involved in a variety of legal matters that arise in the normal course of business. Based on information available, management evaluates the relevant range and likelihood of potential outcomes. In accordance with SFAS No. 5, “Accounting for Contingencies”, management records the appropriate liability when the amount is deemed probable and estimable.

Note 4: Accounting Changes

Estimated Useful Life

During the quarter ended June 30, 2006, the Company commissioned a study of the manufacturing equipment at its worldwide locations, which included an assessment of the estimated useful lives of those assets. The results of the study supported an estimated useful life of 10 years. Management, factoring in the results of this study, has revised the estimated useful lives of its manufacturing equipment for depreciation purposes to 10 years as of the beginning of the second quarter of 2006 and on a prospective basis. The effect of this change was to decrease depreciation expense by $5.4 million, increase net income by $5.4 million and increase both basic and diluted net income per share by $0.02 and $0.02 for the quarter ended March 30, 2007.

Adoption of FASB Interpretation No. 48 Accounting for Uncertain Tax Positions

The Company files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2001.

As of January 1, 2007, the Company adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertain Tax Provisions” (“FIN 48”). As a result of the adoption of FIN 48, the Company recognized the cumulative effect of applying the provisions of FIN 48 as an $8.9 million change to the opening balance of accumulated deficit as of January 1, 2007. The amount of unrecognized tax benefit as of January 1, 2007 after the FIN 48 adjustment was $25.8 million.

March 2007 Amendment to Senior Bank Facilities

In March 2007, the Company refinanced the term loans under its senior bank facilities to reduce, among other things, the interest rate from LIBOR plus 2.25% to LIBOR plus 1.75%. The amended and restated credit agreement also extended the maturity date of the facilities by approximately four years to 2013. Additionally, using cash generated from operations, the Company repaid approximately $23.9 million of the term loans under the senior bank facilities. Terms within the Company’s senior bank facilities contain financial and other covenants more restrictive than those that are currently applicable should the Company exceed minimum leverage and secured leverage ratios as specified therein.

Income per common share
Basic:	$	0.19	$	0.13

Diluted:	$	0.18	$	0.12

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

Diluted income per share incorporates the incremental impact of shares issuable upon the assumed exercise of stock options for the quarters ended March 30, 2007 and March 31, 2006 and upon the assumed conversion of the zero coupon convertible senior subordinated notes for the quarter ended March 31, 2006.

The number of incremental shares from the assumed exercise of stock options is calculated by applying the treasury stock method. Common shares relating to the employee stock options where the exercise price exceeded the average market price of the Company’s common shares or the assumed exercise would have been anti-dilutive during these periods were also excluded from the diluted earnings per share calculation. The excluded option shares were 7.0 million and 8.7 million for the quarter ended March 30, 2007 and March 31, 2006, respectively.

For the quarter ended March 30, 2007, the assumed conversion of the zero coupon convertible senior subordinated notes due 2024 was also excluded in determining diluted earnings per share as the impact would have been anti-dilutive. The zero coupon convertible senior subordinated notes are convertible into cash up to the par value of $260.0 million, based on a conversion price of $9.82 per share. The excess of fair value over par value is convertible into stock. As of March 30, 2007, the Company’s common stock traded below $9.82 per share; thus, the effects of an assumed conversion would have been anti-dilutive and therefore were excluded.

For the quarter ended March 30, 2007, the assumed conversion of the 2.625% convertible senior subordinated notes was also excluded in determining diluted earnings per share. The 2.625% convertible senior subordinated notes are convertible into cash up to the par value of $484.0 million, based on an initial conversion price of approximately $10.50 per share. The excess of fair value over par value is convertible into stock. As of March 30, 2007, the Company’s common stock traded below $10.50; thus, the effects of an assumed conversion would have been anti-dilutive and therefore were excluded.

Treasury Stock is recorded at cost and is presented as a reduction of stockholders’ equity in the accompanying consolidated financial statements. None of these shares had been reissued or retired as of March 30, 2007.

Note 8: Employee Stock Benefit Plans

Stock Options

There was an aggregate of 20.7 million and 18.5 million shares of common stock available for grant under the Company’s stock option plans at March 30, 2007 and December 31, 2006, respectively. The fair value of each option grant is estimated on the date of grant using a lattice-based option valuation model. The weighted-average estimated fair value of stock options granted during the quarters ended March 30, 2007 and March 31, 2006 was $3.59 and $2.97 per share, respectively, and was calculated using the lattice model with the following weighted-average assumptions (annualized percentages):


	Quarter Ended March 30, 2007		Quarter Ended March 31, 2006
Volatility	41.2	%	49.0	%
Risk-free interest rate	4.5	%	4.7	%
Post-vesting forfeiture rate	8.1	%	9.3	%
Rate of exercise	35.9	%	28.6	%

The expected life for options granted during the quarters ended March 30, 2007 and March 31, 2006 derived from the lattice model was 4.2 and 4.0 years, respectively. Pre-vesting forfeitures were estimated to be approximately 13% and 16% in the quarter ended March 30, 2007 and March 31, 2006, respectively, based on historical experience.

A summary of stock option transactions for all stock option plans follows (in millions, except per share and

Employee Stock Purchase Plans

As of March 30, 2007, there were 2.7 million shares available for issuance under the Employee Stock Purchase Plan. The Company continues to use the Black-Scholes option-pricing model to calculate the fair value of shares issued under the 2000 Employee Stock Purchase Plan. The weighted-average fair value of shares issued under the Employee Stock Purchase Plan during the quarters ended March 30, 2007 and March 31, 2006 was $1.75 per share and $1.33 per share, respectively. The weighted-average assumptions used in the pricing model are as follows:

Total	$	40.5

⁽¹⁾	Minimum payments have not been reduced by minimum sublease rentals of $0.5 million due in the future under subleases. Minimum payments include the interest portion of payments for capital lease obligations.

Other Contingencies

The Company’s headquarters and manufacturing facility in Phoenix, Arizona is located on property that is a “Superfund” site, a property listed on the National Priorities List and subject to clean-up activities under the Comprehensive Environmental Response, Compensation, and Liability Act. Motorola is actively involved in the cleanup of on-site solvent contaminated soil and groundwater and off-site contaminated groundwater pursuant to consent decrees with the State of Arizona. As part of the August 4, 1999 recapitalization, Motorola has retained responsibility for this contamination, and has agreed to indemnify the Company with respect to remediation costs and other costs or liabilities related to this matter.

Manufacturing facilities in Slovakia and in the Czech Republic have ongoing remediation projects to respond to releases of hazardous substances that occurred during the years that these facilities were operated by government-owned entities. In each case, these remediation projects consist primarily of monitoring groundwater wells located on-site and off-site with additional action plans developed to respond in the event activity levels are exceeded at each of the respective locations. The governments of the Czech Republic and Slovakia have agreed to indemnify the Company and the respective subsidiaries, subject to specified limitations, for remediation costs associated with this historical contamination. Based upon the information available, total future remediation costs to the Company are not expected to be material.

The Company’s design center in East Greenwich, Rhode Island has adjoining 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. Based on the information available, any costs to the Company in connection with this matter are not expected to be material.

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

- 22 -

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

(unaudited)

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 intellectual property 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 is a party to various agreements with Motorola which were entered into in connection with the Company’s separation from Motorola. Pursuant to these agreements, the Company has agreed to indemnify Motorola for losses due to, for example, breach of representations and warranties and covenants, damages arising from assumed liabilities or relating to allocated assets, and for specified environmental matters. The Company’s obligations under these agreements may be limited in terms of time and/or amount and payment by the Company is conditioned on Motorola making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge Motorola’s claims.

In connection with the acquisition of the LSI’s Gresham, Oregon wafer fabrication facility, the Company entered into various agreements with LSI. Pursuant to certain of these agreements, the Company agreed to indemnify LSI for certain things limited in the most instances by time and/or monetary amounts.

The Company and its subsidiaries provide for indemnification of directors, officers and other persons in accordance with limited liability agreements, certificates of incorporation, by-laws, articles of association or similar organizational documents, as the case may be. The Company maintains directors’ and officers’ insurance, which should enable it to recover a portion of any future amounts paid.

In addition to the above, from time to time the Company provides standard representations and warranties to counterparties in contracts in connection with sales of its securities and the engagement of financial advisors and also provides indemnities that protect the counterparties to these contracts in the event they suffer damages as a result of a breach of such representations and warranties or in certain other circumstances relating to the sale of securities or their engagement by the Company.

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 condition, results of operations or cash flows.

Legal Matters

We currently are involved in a variety of legal matters that arise in the normal course of business. Based on information currently available, management does not believe that the ultimate resolution of these matters, including the matter described in the next paragraphs, will have a material adverse effect on our financial condition, results of operations or cash flows. However, because of the nature and inherent uncertainties of litigation, should the outcome of this action be unfavorable, our business, financial condition, results of operations or cash flows could be materially and adversely affected.

Securities Class Action Litigation

During the period July 5, 2001 through July 27, 2001, the Company was named as a defendant in three shareholder class action lawsuits that were filed in federal court in New York City against the Company and certain of its former officers, current and former directors and the underwriters for the Company’s initial public offering. The lawsuits allege violations of the federal securities laws and have been docketed in the U.S. District Court for the Southern District of New York as: Abrams v. ON Semiconductor Corp., et al. , C.A. No. 01-CV-6114; Breuer v. ON Semiconductor Corp., et al. , C.A. No. 01-CV-6287; and Cohen v. ON Semiconductor Corp., et al. , C.A. No. 01-CV-6942 (“District Court”). On April 19, 2002, the plaintiffs filed a single consolidated amended complaint that supersedes the individual complaints originally filed. The amended complaint alleges, among other things, that the

- 23 -

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

(unaudited)

underwriters of the Company’s initial public offering improperly required their customers to pay the underwriters’ excessive commissions and to agree to buy additional shares of the Company’s common stock in the aftermarket as conditions of receiving shares in the Company’s initial public offering. The amended complaint further alleges that these supposed practices of the underwriters should have been disclosed in the Company’s initial public offering prospectus and registration statement. The amended complaint alleges violations of both the registration and antifraud provisions of the federal securities laws and seeks unspecified damages. The Company understands that various other plaintiffs have filed substantially similar class action cases against approximately 300 other publicly-traded companies and their public offering underwriters in New York City, which have all been transferred, along with the case against the Company, to a single federal district judge for purposes of coordinated case management. The Company believes that the claims against the Company are without merit and have defended, and intend to continue to defend, the litigation vigorously. The litigation process is inherently uncertain, however, and the Company cannot guarantee that the outcome of these claims will be favorable for the Company.

On July 15, 2002, together with the other issuer defendants, the Company filed a collective motion to dismiss the consolidated, amended complaints against the issuers on various legal grounds common to all or most of the issuer defendants. The underwriters also filed separate motions to dismiss the claims against them. In addition, the parties have stipulated to the voluntary dismissal without prejudice of the Company’s individual former officers and current and former directors who were named as defendants in the Company’s litigation, and they are no longer parties to the litigation. On February 19, 2003, the District Court issued its ruling on the motions to dismiss filed by the underwriter and issuer defendants. In that ruling the District Court granted in part and denied in part those motions. As to the claims brought against the Company under the antifraud provisions of the securities laws, the District Court dismissed all of these claims with prejudice, and refused to allow plaintiffs the opportunity to re-plead these claims. As to the claims brought under the registration provisions of the securities laws, which do not require that intent to defraud be pleaded, the District Court denied the motion to dismiss these claims as to the Company and as to substantially all of the other issuer defendants as well. The District Court also denied the underwriter defendants’ motion to dismiss in all respects.

In June 2003, upon the determination of a special independent committee of the Company’s Board of Directors, the Company elected to participate in a proposed settlement with the plaintiffs in this litigation. If ultimately approved by the District Court, this proposed settlement would result in the dismissal, with prejudice, of all claims in the litigation against the Company and against any of the other issuer defendants who elect to participate in the proposed settlement, together with the current or former officers and directors of participating issuers who were named as individual defendants. The proposed settlement does not provide for the resolution of any claims against the underwriter defendants, and the litigation against those defendants is continuing. The proposed settlement provides that the class members in the class action cases brought against the participating issuer defendants will be guaranteed a recovery of $1.0 billion by the participating issuer defendants. If recoveries totaling less than $1.0 billion are obtained by the class members from the underwriter defendants, the class members will be entitled to recover the difference between $1.0 billion and the aggregate amount of those recoveries from the participating issuer defendants. If recoveries totaling $1.0 billion or more are obtained by the class members from the underwriter defendants, however, the monetary obligations to the class members under the proposed settlement will be satisfied. In addition, the Company and any other participating issuer defendants will be required to assign to the class members certain claims that the Company may have against the underwriters of the Company’s initial public offerings.

The proposed settlement contemplates that any amounts necessary to fund the settlement or settlement-related expenses would come from participating issuers’ directors and officers’ liability insurance policy proceeds, as opposed to funds of the participating issuer defendants themselves. A participating issuer defendant could be required to contribute to the costs of the settlement if that issuer’s insurance coverage were insufficient to pay that issuer’s allocable share of the settlement costs. The Company expects that its insurance proceeds will be sufficient for these purposes and that the Company will not otherwise be required to contribute to the proposed settlement.

Consummation of the proposed settlement is conditioned upon obtaining approval by the District Court. On September 1, 2005, the District Court preliminarily approved the proposed settlement and directed that notice of the terms of the proposed settlement be provided to class members. Thereafter, the District Court held a fairness hearing on April 24, 2006, at which objections to the proposed settlement were heard. After the fairness hearing, the District Court took under advisement whether to grant final approval to the proposed settlement.

On December 5, 2006, the U.S. Court of Appeals for the Second Circuit (“Court of Appeals”) issued a decision in In re Initial Public Offering Securities Litigation that six purported class action lawsuits containing allegations substantially similar to those asserted against the Company may not be certified as class actions due, in part, to the Court of Appeals’ determination that individual issues of reliance and knowledge would predominate over issues common to the proposed classes. On January 8, 2007, the plaintiffs filed a petition seeking rehearing en banc of the Court of Appeals’ decision. On April 6, 2007 the Court of Appeals denied the plaintiffs’ petition for rehearing of the Court of Appeals’ December 5, 2006 ruling but noted that the plaintiffs remain free to ask the District Court to certify a different class which might meet the standards for class certification that the Court of Appeals articulated in its December 5, 2006 decision. Because the Company’s proposed settlement with the plaintiffs involves the certification of the case against the Company as a class action for settlement purposes, the impact of the Court of Appeals’ rulings on the possible settlement of the case cannot now be predicted.

If the proposed settlement described above is not consummated, the Company intends to continue to defend the litigation vigorously. While the Company can make no promises or guarantees as to the outcome of these proceedings, it believes that the final result of these actions will have no material effect on the Company’s consolidated financial condition, results of operations or cash flows.

Note 10: Recent Accounting Pronouncements

In September of 2006, the FASB issued SFAS No. 157 “Fair Value Measurements” (SFAS No. 157). SFAS No. 157 establishes a framework for measuring fair value under generally accepted accounting procedures and expands disclosures on fair value measurements. This statement applies under previously established valuation pronouncements and does not require the changing of any fair value measurements, though it may cause some valuation procedures to change. Under SFAS No. 157, fair value is established by the price that would be received to sell the item or the amount to be paid to transfer the liability of the asset as opposed to the price to be paid for the asset or received to transfer the liability. Further, it defines fair value as a market specific valuation as opposed to an entity specific valuation, though the statement does recognize that there may be instances when the low amount of market activity for a particular item or liability may challenge an entity’s ability to establish a market amount. In the instances that the item is restricted, this pronouncement states that the owner of the asset or liability should take into consideration what affects the restriction would have if viewed from the perspective of the buyer or assumer of the liability. This statement is effective for all assets valued in financial statements for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact of SFAS No. 157 to its financial position and result of operations.

In February, 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of FASB Statement No. 115” (SFAS No. 159). SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS No. 159 is expected to expand the use of fair value measurement, which is consistent with the Board’s long-term measurement objectives for accounting for financial instruments. This statement is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007, although earlier adoption is permitted. The Company is currently evaluating the impact of SFAS No. 159 on its financial position and results of operations.

Note 11: Related Party

As described in Note 1 “Background and Basis of Presentation”, on August 4, 1999, certain related transactions were effected pursuant to an agreement among the Company, SCI LLC and TPG. As of March 30, 2007, TPG owned approximately 17.3% of the Company’s outstanding shares of common stock.

During the quarter ended March 30, 2007, the Company incurred approximately $0.2 million of costs and expenses on behalf of TPG in connection with a prospectus supplement for the sale of approximately 45.0 million shares of the Company’s common stock, which were owned by TPG.

Note 12: Segment Information

The Company is organized into five operating segments, which also represent five reporting segments: automotive and power regulation, computing, digital and consumer, standard products (which includes products that are sold in many different end-markets) and manufacturing services. Each of the Company’s major product lines has been examined and each product line has been assigned to a segment, as illustrated in the table below, based on the Company’s operating strategy. Because many products are sold into different end markets, the total revenue reported for a segment is not indicative of actual sales in the end market associated with that segment, but rather is the sum of the revenue from the product lines assigned to that segment. The Company’s manufacturing services, in which the Company manufactures parts for other semiconductor companies, principally in the newly acquired Gresham, Oregon facility, are reported in the manufacturing services segment. These segments represent the Company’s view of the business and as such are used to evaluate progress of major incentives. Information related to periods prior to this change has been revised to conform to the current presentation.


Automotive & Power Regulation	Computing Products	Digital & Consumer Products	Standard Products	Manufacturing Services
AC-DC Conversion	Low & Medium MOSFET	Analog Switches	Bipolar Power	Manufacturing Services

Analog Automotive	Power Switching	Filters	Thyristor

DC-DC Conversion	Signal & Interface	Low Voltage	Small Signal

Rectifier		App. Specific Int. Power	Zener

High Voltage MOSFET			Protection

LDO & Vregs			High Frequency Standard Logic

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company does not specifically identify and allocate any assets by operating segment. The Company evaluates performance based on gross profit as well as income or loss from operations before interest, nonrecurring gains and losses, foreign exchange gains and losses, income taxes and certain other unallocated expenses.

The Company’s wafer manufacturing facilities fabricate integrated circuits for all business units as necessary and their operating costs are reflected in the segments’ cost of revenues on the basis of product costs. Because operating segments are generally defined by the products they design and sell, they do not make sales to each other. The Company does not discretely allocate assets to its operating segments, nor does management evaluate operating segments using discrete asset information.

In addition to the operating segments mentioned above, the Company also operates global operations, sales and marketing, information systems, finance and administration groups that are led by executive or senior vice presidents who report to the Chief Executive Officer. The expenses of these groups are allocated to the operating segments based on specific and general criteria and are included in the operating results reported below. The Company does not allocate income taxes or interest expense to its operating segments as the operating segments are principally evaluated on operating profit before interest and taxes. Additionally, restructuring, asset impairments and other, net and certain other manufacturing and operating expenses, which include corporate research and development costs, inventory reserves and miscellaneous nonrecurring expenses, are not allocated to any operating segment.

Information about segments for the quarter ended March 30, 2007 and for the quarter ended March 31, 2006 is as follows, (in millions):

Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion in conjunction with our audited historical consolidated financial statements, which are included in our Form 10-K, filed with the SEC on February 23, 2007 and our unaudited consolidated financial statements for the fiscal quarter ended March 30, 2007 included elsewhere in this Form 10-Q. Management’s Discussion and Analysis of Financial Condition and Results of Operations contains statements that are forward-looking. These statements are based on current expectations and assumptions that are subject to risks, uncertainties and other factors. Actual results could differ materially because of certain factors discussed below or elsewhere in this Form 10-Q.

Executive Overview

This Executive Overview presents summary information regarding our industry, markets and operating trends only. For further information regarding the events summarized herein, you should read “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in its entirety.

Industry Overview

We participate in unit and revenue surveys and use data summarized by the World Semiconductor Trade Statistics (“WSTS”) group to evaluate overall semiconductor market trends and also to track our progress against the total market in the areas we provide semiconductor components. The most recently published estimates of WSTS project a compound annual growth rate in our total addressable market of approximately 6.9% during 2007 through 2009. These are projections and may not be indicative of actual results.

Business and Company Overview

We classify our products broadly as power and data management semiconductors and standard semiconductor components. We design, manufacture and market an extensive portfolio of semiconductor components that addresses the design needs of sophisticated electronic systems and products. Our power management semiconductor components control, convert, protect and monitor the supply of power to the different elements within a wide variety of electronic devices. Our data management semiconductor components provide high-performance clock management and data flow management for precision computing and communications systems. Our standard semiconductor components serve as “building block” components within virtually all electronic devices. These various products fall into the logic, analog and discrete categories used by WSTS.

We serve a broad base of end-user markets, including computing, automotive electronics, consumer electronics, industrial electronics, wireless communications and networking. Applications for our products in these markets include portable electronics, computers, game stations, servers, automotive and industrial automation control systems, routers, switches, storage-area networks and automated test equipment.

- 29 -

Our extensive portfolio of devices enables us to offer advanced integrated circuits and the “building block” components that deliver system level functionality and design solutions. Our product portfolio currently comprises approximately 28,800 products and we shipped approximately 7.5 billion units in the first quarter of 2007 as compared to approximately 7.6 billion units in the first quarter of 2006. We specialize in micro packages, which offer increased performance characteristics while reducing the critical board space inside today’s ever shrinking electronic devices. We believe that our ability to offer a broad range of products provides our customers with single source purchasing on a cost-effective and timely basis.

We are organized into five operating segments, which also represent five reporting segments: automotive and power regulation, computing, digital and consumer, standard products (which include products that are sold in many different end-markets) and manufacturing services. Each of our major product lines has been assigned to a segment, as illustrated in the table below, based on our operating strategy. Because many products are sold into different end markets, the total revenue reported for a segment is not indicative of actual sales in the end market associated with that segment, but rather is the sum of the revenues from the product lines assigned to that segment. Our manufacturing services, in which we manufacture parts for other semiconductor companies, principally in our newly acquired Gresham, Oregon facility, are reported in the manufacturing services segment. These segments represent our view of the business and as such are used to evaluate progress of major initiatives. Information related to periods prior to this change have been revised to conform to the current presentation.

We have approximately 158 direct customers worldwide, and we also service approximately 204 significant original equipment manufacturers indirectly through our distributor and electronic manufacturing service provider customers. Our direct and indirect customers include: (1) leading original equipment manufacturers in a broad variety of industries, such as Apple, Continental Automotive Systems, Hewlett Packard, Microsoft, Intel, Motorola, Seagate, Siemens and Sony; (2) electronic manufacturing service providers, such as Flextronics, Jabil and Solectron; and (3) global distributors, such as Arrow, Avnet, EBV Elektronik, Future, Solomon Enterprise and World Peace.

We currently have major design operations in Arizona, Rhode Island, Texas, Oregon, China, Slovakia, the Czech Republic, Korea, and France, and we currently operate manufacturing facilities in Arizona, Oregon, China, the Czech Republic, Japan, Malaysia, the Philippines, and Slovakia. In the first quarter of 2007, we announced the planned closing of one of our Arizona manufacturing facilities for cost savings purposes. The wafer manufacturing that takes place at this facility will be transferred to our other manufacturing facilities. We plan to sell the wafer fabrication facility and associated land. We also continue to market additional unused portions of our property at our corporate headquarters in Arizona and plan to use some of the proceeds from the sale to upgrade portions of our corporate headquarters. During the first quarter of 2007 we entered into an agreement to sell approximately 20 acres of the land for approximately $11.5 million. If the sale is completed, at the originally contracted price, we expect to record a gain of approximately $10.0 million during the quarter in which the transaction closes. The remaining property and buildings, excluding the wafer manufacturing facility are currently being marketed for sale. We will maintain our headquarters offices and remaining manufacturing facilities on the portions of the property that are not for sale.

On May 15, 2006, we, through our principal domestic operating subsidiary, Semiconductor Components Industries, LLC (“SCI LLC”), purchased LSI Logic Corporation’s (“LSI”) Gresham, Oregon wafer fabrication facility, including real property, tangible personal

- 30 -

property, certain intangible assets, other specified manufacturing equipment and related information. The purchase of the Gresham wafer facility significantly enhances our internal manufacturing capabilities. With this facility, we have gained process development engineers, operational expertise and process development know-how to help enable us to develop a larger mix of high volume, low cost, high-performance submicron analog and digital power products down to the 0.18 micron level, with toolset capabilities down to the 0.13 micron level in the future.

Historically, the semiconductor industry has been highly cyclical. During a down cycle, unit demand and pricing have tended to fall in tandem, resulting in revenue declines. In response to such declines, manufacturers have shut down production capacity. When new applications or other factors have eventually caused demand to strengthen, production volumes have eventually stabilized and then grown again. As market unit demand has reached levels above capacity production capabilities, shortages have begun to occur, which typically has caused pricing power to swing back from customers to manufacturers, thus prompting further capacity expansion. Such expansion has typically resulted in overcapacity following a decrease in demand, which has triggered another similar cycle.

During the first quarter of 2007, we experienced a decrease in the end market unit demand and price decreases which resulted in decreased revenue compared to our previous quarter. We expect our second quarter product revenues to grow slightly thereby indicating we have entered the growth phase of a new cycle.

New Product Innovation

As a result of the success of our research and development initiatives, excluding the introduction of lead-free products, we introduced 133 new product families in 2006 and an additional 20 new product families in the first quarter of 2007. Our new product development efforts continue to be focused on building solutions in power management that appeal to customers in focused market segments and across multiple high growth applications. In light of the recent acquisition of the Gresham, Oregon wafer fabrication facility, we are increasing our research and development in deep sub micron power management solutions to further differentiate us from our competition. As always, it is our practice to regularly re-evaluate our research and development spending, to assess the deployment of resources and to review the funding of high growth technologies regularly. We deploy people and capital with the goal of maximizing our investment in research and development in order to position us for continued growth. As a result, we often invest opportunistically to refresh existing products in our commodity logic, analog, and discrete products. We invest in these initiatives when we believe there is a strong customer demand or opportunities to innovate our current portfolio in high growth markets and applications.

Cost Savings and Restructuring Activities

We continue to implement profitability enhancement programs to improve our cost structure and, as a result, we expect to rank, as compared to our primary competitors, among the lowest in terms of cost structure. During the first quarter of 2007, we announced plans to consolidate manufacturing efforts with the closing of one of our manufacturing facilities at our Phoenix, Arizona location. The wafer manufacturing that takes place at this facility will be transferred to our off shore low cost manufacturing facilities, and we expect this transfer to be completed during the first half of 2008. After we have completed the transfer to other facilities, we plan to sell the wafer fabrication facility at our Phoenix location. It is anticipated that approximately 110 employees will be terminated as a result of this consolidation effort. We expect the full annual cost savings from this consolidation to be at least $7.0 million to $9.0 million beginning in the third quarter of 2008.

Although we have production at several locations, we have initiated process improvements and selective capital acquisitions that we expect will increase our overall capacity. Our profitability enhancement programs will continue to focus on:

•

consolidating manufacturing sites to improve economies of scale;

•

transferring production to lower cost regions;

- 31 -

•

increasing die manufacturing capacity in a cost-effective manner by moving production from 4” to 6” and 8” wafers and increasing the number of die per square inch;

•

reducing of the number of product platforms and process flows; and

•

focusing production on profitable product families.

Debt Reduction and Financing Activities

Since our 1999 recapitalization, we have had relatively high levels of long-term debt as compared to our principal competitors. During 2002 and 2003, we engaged in several debt refinancing transactions, which extended a portion of our debt maturities. Since 2003, however, we began undertaking measures to reduce our long-term debt and related interest costs. As a result of these measures, we reduced our total debt from $1,302.9 million as of December 31, 2003 to $1,150.4 million as of March 30, 2007. Similarly, our 2003 average quarterly interest expense of $37.8 million has declined, and we recorded $9.7 million of interest expense in the first quarter of 2007. Also, see “Liquidity and Capital Resources” and Note 6 “Long-term debt” of the notes to our unaudited consolidated financial statements included elsewhere in this Form 10-Q.

Outlook

Based upon booking trends, backlog levels, anticipated manufacturing services revenue and estimated turns levels, we anticipate that total revenues will be approximately $375.0 million to $385.0 million in the second quarter of 2007 as compared to revenues of $375.3 million in the second quarter of 2006 and revenues of $374.2 million in the first quarter of 2007. We also anticipate that approximately $25.0 million of our total revenues will come from manufacturing services revenues during the second quarter of 2007. Backlog levels at the beginning of the second quarter of 2007 were down slightly from backlog levels at the beginning of the first quarter of 2007, and represented approximately 85 percent of our anticipated second quarter 2007 revenues. We expect average selling prices will be down approximately one to two percent in the second quarter of 2007. We expect our product gross margins to be approximately 39 to 40 percent and our manufacturing services gross margin to be similar to that of the first quarter of 2007 in the second quarter of 2007. We currently expect our stock based compensation expense to be approximately $3.0 million to $4.0 million in the second quarter of 2007.

For the second quarter of 2007, we expect selling and marketing and general and administrative expenses at approximately 11% to 12% of revenues and research and development expenses at approximately 8% of revenues. We anticipate that net interest expense and income tax provision will be approximately $7.0 million and $2.5 million, respectively, for the second quarter of 2007. We expect fully diluted common shares outstanding to be approximately 305 million shares in the second quarter of 2007 based on the share price of our common stock as of April 26, 2007. We anticipate cash capital expenditures will be approximately $40.0 million in the second quarter of 2007.

Revenues

Net revenues were $374.2 million and $334.0 million during the quarters ended March 30, 2007 and March 31, 2006, respectively. The increase from the first quarter of 2006 to the first quarter of 2007 was primarily due to increased product volume and manufacturing services revenue resulting from the acquisition of LSI’s Gresham, Oregon wafer fabrication facility, partially offset by a decrease in average selling prices by approximately 2%. As indicated in the table below, the increase was most pronounced in the manufacturing services and in the digital and consumer products segments. The revenues by reportable segment were as follows (dollars in millions):


	Quarter Ended March 30, 2007		As a % Revenue		Quarter Ended March 31, 2006		As a % Revenue⁽¹⁾		Dollar Change			% Change

(1)	Certain amounts may not total due to rounding of individual amounts.

Revenues from automotive and power regulation increased $7.3 million, or 7.4%, in the first quarter of 2007 as compared to the first quarter of 2006. The increase is attributed to an increase in revenues from the DC to DC conversion, AC to DC conversion, rectifier, LDO and voltage regulator products, partially offset by decreases in revenues from analog automotive products.

- 33 -

Revenues from computing products increased $3.4 million, or 4.4%, in the first quarter of 2007 as compared to the first quarter of 2006. The increase is attributed to an increase in revenues from power switching and signal and interface products, partially offset by decreases in revenues from low and medium voltage MOSFET products.

Revenues from digital and consumer products increased $16.2 million, or 62.3%, in the first quarter of 2007 as compared to the first quarter of 2006. This increase is due to increased revenues from analog switches, filters, and low voltage products.

Revenues from standard products decreased $12.1 million, or 9.2%, in the first quarter of 2007 as compared to the first quarter of 2006. The decrease is primarily attributed to a decrease in revenues from standard logic, small signal, and thyristor products, partially offset by increased revenues in protection and zener products.

Additionally, revenue growth in manufacturing services is due to the manufacturing services revenue from the wafer supply agreement with LSI that began in the second quarter of 2006 related to our purchase of LSI’s Gresham, Oregon wafer fabrication facility.

Revenues by geographic area as a percentage of revenues were as follows (dollars in millions):


	Quarter Ended March 30, 2007		As a % Revenue⁽¹⁾		Quarter Ended March 31, 2006		As a % Revenue⁽¹⁾
Americas	$	100.6	27	%	$	77.2	23	%

(1)

Certain amounts may not total due to rounding of individual amounts.

A majority of our end customers, served directly or through distribution channels, are manufacturers of electronic devices.

For the quarter ended March 30, 2007, one of our customers accounted for 13% of our net revenues.

For the quarter ended March 31, 2006, two of our customers accounted for 11% and 10% of our net revenues.

Approximately 16% of our revenues for the quarter ended March 30, 2007, are attributable to our various automotive customers. Certain of these automotive customers have been experiencing a downturn in their business, in part due to labor difficulties. On October 8, 2005, Delphi Corporation (“Delphi”), one of our automotive customers, and certain of Delphi’s U.S. subsidiaries commenced reorganization proceedings under Chapter 11 of the U.S. Federal Bankruptcy Code. During the quarter ended March 30, 2007, our revenues from Delphi accounted for less than 3% of our total revenues. During the quarter ended March 30, 2007, we sold, without discount, to a third party with recourse to us all of our receivables due from Delphi totaling $5.4 million, all of which are subject to collection pending resolution of the reorganization proceedings.

Gross Profit

Our gross profit was $136.6 million in the first quarter of 2007 compared to $117.7 million in the first quarter of 2006. As a percentage of revenues, our gross profit was 36.5% in the first quarter of 2007 as compared to 35.2% in the first quarter of 2006. Gross profit increased during the first quarter of 2007 as compared to the first quarter of 2006 primarily due to increased sales volume and a reduction in depreciation expense of approximately $5.4 million resulting from a change in our estimate of the useful life of our machinery and equipment assets. See Note 4 “Accounting Changes” of the notes to our unaudited consolidated financial statements included elsewhere in this Form 10-Q. The gross profit by reportable segment in each of these quarters were as follows (dollars in millions):

Total gross profit	$	136.6		36.5	%	$	117.7		35.2	%

Gross profit from automotive and power regulation increased $3.0 million, or 7.7%, in the first quarter of 2007 as compared to the first quarter of 2006. The increase can be attributed to increased gross profit from DC to DC conversion, AC to DC conversion, analog automotive and LDO and voltage regulators products, partially offset by decreases in gross profit from rectifier and high voltage MOSFET products.

Gross profit from computing products increased $4.3 million, or 16.8%, in the first quarter of 2007 as compared to the first quarter of 2006. The increase can be attributed to increases in gross profit from low and medium voltage MOSFET and signal and interface products, partially offset by decreases in gross profit from power switching products.

Gross profit from digital and consumer products increased $8.6 million, or 67.2%, in the first quarter of 2007 as compared to the first quarter of 2006. The increase can be attributed to increases in gross profit in the analog switches, filters, and low voltage products, partially offset by a decrease in gross profit from standard logic products.

Gross profit from standard products decreased $3.3 million, or 5.7%, in the first quarter of 2007 as compared to the first quarter of 2006. The increase can be primarily attributed to an increase in gross profit from zener and protection products, partially offset by a decrease in gross profit in high frequency, small signal, and standard logic products.

Gross profit from manufacturing services decreased $2.5 million in the first quarter of 2007 as compared to the first quarter of 2006.

Operating Expenses

Research and development expenses were $30.8 million in the first quarter of 2007 compared to $23.6 million in the first quarter of 2006, representing an increase of $7.2 million, or 30.5%. Research and development expenses represented 8.2% and 7.1% of revenues in the first quarter of 2007 and the first quarter of 2006, respectively. The increase in research and development expenses was attributable to increased employee salaries and wages and increased headcount as well as increased stock compensation expense. Additionally, increased costs associated with research of new product technology, combined with increase in engineering fees. The above increases are slightly offset by a decrease in performance bonus.

Selling and marketing expenses were $22.9 million in the first quarter of 2007 compared to $21.0 million in the first quarter of 2006, representing an increase of $1.9 million, or 9%. Selling and marketing expenses represented 6.1% and 6.3% of revenues in the first quarter of 2007 and the first quarter of 2006, respectively. The increase in selling and marketing expenses is primarily attributable to increased employee salaries and wages from higher head count.

General and administrative expenses were $20.2 million in the first quarter of 2007 compared to $20.2 million in the first quarter of 2006, representing no increase year over year. General and administrative expenses represented 5.4% and 6.0% of revenues in the first quarter of 2007 and the first quarter of 2006, respectively.

Interest Expense

Interest expense was $9.7 million in the first quarter of 2007 compared to $13.0 million in the first quarter of 2006. The decrease in interest expense was primarily a result of interest savings during the first quarter of 2007 that resulted from the prepayment of our senior bank facilities during the fourth quarter of 2006 and during the first quarter of 2007. Our average month-end long-term debt balance (including current maturities) in the first quarter of 2007 was $1,172.8 million with a weighted average interest rate of 3.3% compared to $1,106.5 million and a weighted average interest rate of 4.9% in the first quarter of 2006. See also “Liquidity and Capital Resources—Key Financing Events” for a description of our refinancing activities.

Provision for Income Taxes

Provision for income taxes was $0.6 million in the first quarter of 2007 compared to $2.0 million in the first quarter of 2006. The provision for the first quarter of 2007 included $1.9 million for income and withholding taxes of certain of our foreign operations and $0.6 million of new reserves for potential liabilities in foreign taxing jurisdictions, partially offset by the reversal of $1.9 million of previously accrued income taxes for anticipated audit issues. The provision for the first quarter of 2006 included income and withholding taxes of certain of our foreign operations. Due to our continuing domestic tax losses and tax rate differential in our foreign subsidiaries, our effective tax rate is lower than the U.S. statutory federal income tax rate. We continue to maintain a full valuation allowance on all of our domestic deferred tax assets.

Our long-term debt includes $175.0 million outstanding under senior bank facilities, approximately $260.0 million of zero coupon convertible senior subordinated notes due 2024, $95.0 million of 1.875% convertible senior subordinated notes due 2025, $484.0 million of 2.625% convertible senior subordinated notes due 2026, $10.9 million outstanding under a note payable to a Japanese bank, $53.1 million outstanding under loan facilities with two Chinese banks, $0.5 million note payable to Oregon State due 2009 and $71.9 million of capital lease obligations. See Note 6 “Long-Term Debt” of the notes to our unaudited consolidated financial statements included elsewhere in this Form 10-Q.

In the normal course of our business, we enter into various operating leases for equipment including our mainframe computer system, desktop computers, communications, foundry equipment and service agreements relating to this equipment.

Our other long-term contractual obligations consist of estimated payments to fund liabilities that have been accrued in our consolidated balance sheet for our foreign pension plans. (See Note 5 “Balance Sheet Information” of the notes to our unaudited consolidated financial statements included elsewhere in this Form 10-Q).

Our balance of cash and cash equivalents was $275.8 million at March 30, 2007. We believe that our cash flows from operations, coupled with existing cash and cash equivalents will be adequate to fund our operating and capital needs through at least March 30, 2008. Our senior bank facilities include a $25.0 million revolving facility. Letters of credit totaling $4.6 million were outstanding under the revolving facility at March 30, 2007. We amended our primary foreign exchange hedging agreement to provide for termination if at any time the amount available under our revolving credit facility is less than $2.5 million.

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 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 us require us to indemnify the other party against losses due to intellectual property infringement, property damage including environmental contamination, personal injury, failure to comply with applicable laws, our negligence or willful misconduct, or breach of representations and warranties and covenants related to such matters as title to sold assets.

- 37 -

We are a party to various agreements with Motorola, a former affiliate, which were entered into in connection with our separation from Motorola. Pursuant to these agreements, we have agreed to indemnify Motorola for losses due to, for example, breach of representations and warranties and covenants, damages arising from assumed liabilities or relating to allocated assets, and for specified environmental matters. Our obligations under these agreements may be limited in terms of time and/or amount and payment by us is conditioned on Motorola making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow us to challenge Motorola’s claims.

In connection with the acquisition of LSI’s Gresham, Oregon wafer fabrication facility, we entered into various agreements with LSI. Pursuant to certain of these agreements, we have agreed to indemnify LSI for certain things limited in most instances by time and/or monetary amounts.

We provide for indemnification of directors, officers and other persons in accordance with limited liability agreements, certificates of incorporation, by-laws, articles of association or similar organizational documents, as the case may be. We maintain directors’ and officers’ insurance, which should enable us to recover a portion of any future amounts paid.

In addition to the above, from time to time we provide standard representations and warranties to counterparties in contracts in connection with sales of our securities and the engagement of financial advisors and also provide indemnities that protect the counterparties to these contracts in the event they suffer damages as a result of a breach of such representations and warranties or in certain other circumstances relating to the sale of securities or their engagement by us.

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 Part II, Item 1 “Legal Proceedings” of this Form 10-Q for possible contingencies related to legal matters and see Part I, Item 1 “Business—Government Regulation” of our annual report on Form 10-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 research and development, to make capital expenditures, strategic acquisitions and investments, to repurchase our stock, and to pay debt service, including principal and interest and capital lease payments. 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, cash and cash equivalents on hand and targeted asset sales. Additionally, as part of our business strategy, we review acquisition and divestiture opportunities and proposals on a regular basis.

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 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 productivity and our ability to make the research and development expenditures required to remain competitive in our business; and

- 38 -

•

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, our ability to maintain compliance with financial covenants under our existing credit facilities and other limitations imposed by our credit facilities or arising from our substantial leverage.

Our ability to service our long-term debt, to remain in compliance with the various covenants and restrictions contained in our credit 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.

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 will be adequate to fund our operating and capital needs as well as enable us to maintain compliance with our various debt agreements through March 30, 2008. To the extent that results or events differ from our financial projections or business plans, our liquidity may be adversely impacted.

Operations

Our operational cash flows are affected by the ability of our operations to generate cash, and our management of our assets and liabilities, including both working capital and long-term assets and liabilities. Each of these components is discussed herein:

EBITDA

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is a key indicator that management uses to evaluate our operating performance and cash flows. While EBITDA is not intended to represent cash flow from operations as defined by generally accepted accounting principles and should not be considered as an indicator of operating performance or an alternative to cash flow as a measure of liquidity, we believe this measure is useful to investors to assess our ability to meet our future debt service, capital expenditure and working capital requirements. This calculation may differ in method of calculation from similarly titled measures used by other companies. The following table sets forth our EBITDA for the three months ended March 30, 2007, December 31, 2006, and March 31, 2006 with a reconciliation to cash flows from operations, the most directly comparable financial measure under generally accepted accounting principles (in millions):

If we were not in compliance with the covenants contained in our senior bank facilities credit agreement, the lenders under our senior bank facilities credit agreement could cause all outstanding amounts to be due and payable immediately. If we were unable to repay, refinance or restructure that indebtedness, the lenders could proceed against the collateral securing that indebtedness. In addition, any such event of default or declaration of acceleration could also result in an event of default under one or more of our other debt instruments and have a material adverse effect on our financial condition, results of operations and liquidity.

Working Capital

Working capital fluctuates depending on end-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 increase as we purchase additional manufacturing inputs 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. Our working capital, including cash, was $308.9 million at March 30, 2007, and has fluctuated between $202.0 million and $315.8 million over the last eight quarter-ends.

The components of our working capital at March 30, 2007 and December 31, 2006 are set forth below (in millions), followed by explanations for changes between December 31, 2006 and March 30, 2007 for cash and cash equivalents and any other changes greater than $5 million:

Total current liabilities		398.7		433.0		(34.3	)

Net working capital	$	308.9	$	267.8	$	41.1

The increase of $7.0 million in cash and cash equivalents is due to $63.1 million in cash provided by operating activities, partially offset by $43.2 million in cash used in investing activities and $12.7 million in cash used in financing activities.

The decrease of $27.5 million in accounts payable was mainly due to the timing of payments at the respective period ends and a decrease in fixed asset additions during the first quarter of 2007 that remained unpaid as of March 30, 2007, as compared to the fourth quarter of 2006.

The decrease in accrued expenses of $7.4 million was primarily attributable to a decrease in accrued employee performance bonus.

Long-Term Assets and Liabilities

Our long-term assets consist primarily of property, plant and equipment, intangible assets, foreign tax receivables and capitalized debt issuance costs.

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. Capital expenditures were $49.0 million during the first three months of 2007 compared to $31.7 million during the first three months of 2006. 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, consist of liabilities under our foreign defined benefit pension plans and contingent tax reserves. In regard to our foreign defined benefit pension plans, generally, 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.

Key Financing Events

Overview

Since we became an independent company as a result of our 1999 recapitalization, we have had relatively high levels of long-term debt as compared to our principal competitors.

- 41 -

During the second half of 2003, we began undertaking measures to reduce our long-term debt, reduce related interest costs and, in some cases, extend a portion of our debt maturities to continue to provide us additional operating flexibility. These measures continued into 2007, as described below:

March 2007 Amendment to Senior Bank Facilities

In March 2007, we refinanced the term loans under our senior bank facilities to, among other things, reduce the interest rate from LIBOR plus 2.25% to LIBOR plus 1.75%. The amended and restated credit agreement also extended the maturity date of the facilities by approximately four years to 2013. Additionally, we repaid approximately $23.9 million of the term loans under the senior bank facilities during the quarter. Terms within our senior bank facilities contain financial and other covenants more restrictive than those that are currently applicable should we exceed minimum leverage and secured leverage ratios, as specified therein.

Oregon State Note

In January 2007, we recorded the receipt of $0.5 million of proceeds from a loan agreement and promissory note with the State of Oregon for the purpose of developing local business. The total loan is expected to be for $1.5 million and is to be disbursed in three (3) equal payments with each payment conditioned on the completion of certain requirements by us. The note is for the loan amount or so much thereof as has been disbursed. The note matures on July 31, 2009 and carries an annual interest rate of 5.0%. The State of Oregon will forgive all or a portion of the loan and accrued interest upon the satisfaction by us of certain conditions, including maintaining 400 full-time equivalent employees at the Gresham, Oregon facility for a specific period of time.

Debt Instruments, Guarantees and Related Covenants

We have pledged substantially all of our tangible and intangible assets and similar assets of each of our existing and subsequently acquired or organized domestic subsidiaries (but no more than 65% of the capital stock of foreign subsidiaries held by them) to secure our senior bank facilities.

SCI LLC, the primary domestic operating subsidiary of ON Semiconductor Corporation, is the borrower under our senior bank facilities. ON Semiconductor Corporation and our other domestic subsidiaries fully and unconditionally guarantee on a joint and several basis the obligations of the borrower under such facilities. ON Semiconductor Corporation is the issuer, and SCI LLC is a guarantor, of our zero coupon convertible senior subordinated notes due 2024, our 1.875% convertible senior subordinated notes due 2025 and our 2.625% convertible senior subordinated notes due 2026. Our other domestic subsidiaries fully and unconditionally guarantee on a joint and several basis the obligations of the issuers of such notes. None of our non-U.S. subsidiaries guarantee the senior bank facilities or the notes.

As of March 30, 2007, we were in compliance with the various covenants and other requirements contained in the credit agreement relating to our senior bank facilities and the indentures relating to our zero coupon convertible senior subordinated notes due 2024, our 1.875% convertible senior subordinated notes due 2025 and our 2.625% convertible senior subordinated notes due 2026. We believe that we will be able to comply with the various covenants and other requirements contained in such credit agreement and the indentures through March 30, 2008.

- 43 -

Our debt agreements contain, and any future debt agreements may include, a number of restrictive covenants that impose significant operating and financial restrictions on among other things, our ability to:

•

incur additional debt, including guarantees;

•

incur liens;

•

sell or otherwise dispose of assets;

•

make investments, loans or advances;

•

make some acquisitions;

•

engage in mergers or consolidations;

•

pay dividends, redeem capital stock or make certain other restricted payments or investments;

•

pay dividends from Semiconductor Components Industries, LLC to ON Semiconductor Corporation;

•

engage in sale and leaseback transactions;

•

enter into new lines of business;

•

issue some types of preferred stock; and

•

enter into transactions with our affiliates.

Terms within our senior bank facilities contain financial and other covenants more restrictive than those that are currently applicable should we exceed minimum leverage and secured leverage ratios, as specified therein.

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 on a timely basis to allow us to maintain our manufacturing efficiency and support our platforms of new products.

Accounting Changes

During the quarter ended June 30, 2006, we commissioned a study of the manufacturing equipment at its other worldwide locations, which included an assessment of the estimated useful lives of those assets. The results of the study supported an estimated useful life of 10 years. We, factoring in the results of this study, have revised the estimated useful lives of our manufacturing equipment for depreciation purposes to 10 years as of the beginning of the second quarter of 2006 and on a prospective basis. The effect of this change was to decrease depreciation expense by $5.4 million and increase net income by $5.4 million and increase both basic net income per share by $0.02 for the quarter ended March 30, 2007 and diluted net income per share by $0.2 for the quarter ended March 30, 2007.

We or one of our subsidiaries files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2001.

- 44 -

As of January 1, 2007, we adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertain Tax Provisions” (“FIN 48”). As a result of the adoption of FIN 48, we recognized the cumulative effect of applying the provisions of FIN 48 as an $8.9 million change to the opening balance of accumulated deficit as of January 1, 2007. The amount of unrecognized tax benefit as of January 1, 2007 was $25.8 million, including the $8.9 million adjustment.

The entire January 1, 2007 balance of $25.8 million relates to unrecognized tax positions that, if recognized, would affect the annual effective tax rate.

We recognize interest and penalties accrued in relation to unrecognized tax benefits in tax expense. We had approximately $4.0 million for payment of interest and penalties accrued at January 1, 2007.

The impact of the adoption of FIN 48 the opening balance of accumulated deficit as of January 1, 2007 is as follows (in millions):

Critical Accounting Policies and Estimates

The accompanying discussion and analysis of our financial condition and results of operations is based upon our audited consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. We believe certain of our accounting policies are critical to understanding our financial position and results of operations. We utilize the following critical accounting policies in the preparation of our financial statements.

Revenue. We generate revenue from sales of our semiconductor products to original equipment manufacturers, electronic manufacturing service providers and distributors. We also generate revenue, although to a much lesser extent, from manufacturing services provided to customers. We recognize revenue on sales to original equipment manufacturers and electronic manufacturing service providers when title passes to the customer net of provisions for related sales returns and allowances. Title to products sold to distributors typically passes at the time of shipment by us so we record accounts receivable for the amount of the transaction, reduce our inventory for the products shipped and defer the related margin in our consolidated balance sheet. We recognize the related revenue and cost of revenues when the distributor informs us that they have resold the products to the end user. Although payment terms vary, most distributor agreements require payment within 30 days. Taxes assessed by governmental authorities on revenue-producing transactions, including value added and excise taxes, are presented on a net basis (excluded from revenues) in the statement of operations.

Sales returns and allowances are estimated based on historical experience. Given that our revenues consist of a high volume of relatively similar products, our actual returns and allowances do not fluctuate significantly from period to period, and our returns and allowances provisions have historically been reasonably accurate.

Freight and handling costs are included in cost of revenues and are recognized as period expense during the period in which they are incurred.

Inventories. We carry our inventories at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market and record provisions for slow moving inventories based upon a regular analysis of inventory on hand compared to historical and projected end user demand. Projected end user demand is generally based on sales during the prior 12 months. These provisions can influence our results from operations. For example, when demand falls for a given part, all or a portion of the related

- 45 -

inventory is reserved, impacting our cost of revenues and gross profit. If demand recovers and the parts previously reserved are sold, we will generally recognize a higher than normal margin. However, the majority of product inventory that has been previously reserved is ultimately discarded. Although we do sell some products that have previously been written down, such sales have historically been relatively consistent on a quarterly basis and the related impact on our margins has not been material.

Deferred Tax Valuation Allowance. We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income as well as feasible tax planning strategies in each taxing jurisdiction in which we operate. If we determine that we will not realize all or a portion of our remaining deferred tax assets, we will increase our valuation allowance with a charge to income tax expense. Conversely, if we determine that we will ultimately be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be released to income as a credit to income tax expense. In the fourth quarter of 2001, a valuation allowance was established for our domestic deferred tax assets and a portion of our foreign deferred tax assets. Additionally, throughout 2003, 2004, 2005, 2006 and continuing into 2007, no incremental domestic deferred tax benefits were recognized. Our ability to utilize our deferred tax assets and the continuing need for a related valuation allowance are monitored on an ongoing basis.

Impairment of Long-Lived Assets. We evaluate the recoverability of the carrying amount of our property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. Impairment is assessed when the undiscounted expected cash flows derived for an asset are less than its carrying amount. Impairment losses are measured as the amount by which the carrying value of an asset exceeds its fair value and are recognized in operating results. We continually apply our best judgment when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of an impaired asset. The dynamic economic environment in which we operate and the resulting assumptions used to estimate future cash flows impact the outcome of our impairment tests. In recent years, most of our assets that have been impaired consist of assets that were ultimately abandoned, sold or otherwise disposed of due to cost reduction activities and the consolidation of our manufacturing facilities. In some instances, these assets have subsequently been sold for amounts higher than their impaired value. When material, these gains are recorded in the restructuring, asset impairment and other, net line item in our consolidated statement of operations and disclosed in the footnotes to the financial statements.

Goodwill. We evaluate our goodwill for potential impairment on an annual basis or whenever events or circumstances indicate that an impairment may have occurred in accordance with the provisions of Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets” (“SFAS No. 142”), which requires that goodwill be tested for impairment using a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares the estimated fair value of the reporting unit containing our goodwill with the related carrying amount. If the estimated fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step is unnecessary. To date, our goodwill has not been considered to be impaired based on the results of this first step.

Defined Benefit Plans. We maintain pension plans covering certain of our employees. For financial reporting purposes, net periodic pension costs are calculated based upon a number of actuarial assumptions, including a discount rate for plan obligations, assumed rate of return on pension plan assets and assumed rate of compensation increase for plan employees. All of these assumptions are based upon management’s judgment, considering all known trends and uncertainties. Actual results that differ from these assumptions impact the expense recognition and cash funding requirements of our pension plans.

Asset Retirement Obligations. We recognize asset retirement obligations (“AROs”) when incurred, with the initial measurement at fair value. These liabilities are accreted to full value over time through charges to income. In addition, asset retirement costs are capitalized as part of the related asset’s carrying value and are depreciated over the asset’s respective useful life. Our AROs consist primarily of estimated decontamination costs associated with manufacturing equipment and buildings.

Contingencies. We are involved in a variety of legal matters that arise in the normal course of business. Based on the available information, we evaluate the relevant range and likelihood of potential outcomes. In accordance with SFAS No. 5, “Accounting for Contingencies”, we record the appropriate liability when the amount is deemed probable and estimable.

- 46 -

Valuation of Stock Compensation. The fair value of each option grant in 2005 and thereafter is estimated on the date of grant using a lattice-based option valuation model. In past years, we have used the Black-Sholes option-pricing model to calculate the fair value of its options. The lattice model uses: 1) a constant volatility; 2) an employee exercise behavior model (based on an analysis of historical exercise behavior); and 3) the treasury yield curve to calculate the fair value of shares issued each option grant. We use the Black-Scholes option-pricing model to calculate the fair value of shares issued under the 2000 Employee Stock Purchase Plan.

Recent Accounting Pronouncements

In September of 2006, the FASB issued SFAS No. 157 “Fair Value Measurements” (“SFAS No. 157”). SFAS No. 157 establishes a framework for measuring fair value under generally accepted accounting procedures and expands disclosures on fair value measurements. This statement applies under previously established valuation pronouncements and does not require the changing of any fair value measurements, though it may cause some valuation procedures to change. Under SFAS No. 157, fair value is established by the price that would be received to sell the item or the amount to be paid to transfer the liability of the asset as opposed to the price to be paid for the asset or received to transfer the liability. Further, it defines fair value as a market specific valuation as opposed to an entity specific valuation, though the statement does recognize that there may be instances when the low amount of market activity for a particular item or liability may challenge an entity’s ability to establish a market amount. In the instances that the item is restricted, this pronouncement states that the owner of the asset or liability should take into consideration what affects the restriction would have if viewed from the perspective of the buyer or assumer of the liability. This statement effective for all assets valued in financial statements for fiscal years beginning after November 15, 2007. We are currently evaluating the impact of SFAS No. 157 to our financial position and result of operations.

In February, 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of FASB Statement No. 115” (SFAS No. 159). SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS No. 159 is expected to expand the use of fair value measurement, which is consistent with the Board’s long-term measurement objectives for accounting for financial instruments. This statement is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007, although earlier adoption is permitted. We are currently evaluation the impact of SFAS No. 159 to its financial position and results of operations.

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.

At March 30, 2007, our long-term debt (including current maturities) totaled $1,150.4 million. We have no interest rate exposure to rate changes on our fixed rate debt, which totaled $922.3 million. We do have interest rate exposure with respect to the $228.1 million outstanding balance on our variable interest rate debt. A 50 basis point increase in interest rates would impact our expected annual interest expense for the next twelve months by approximately $1.1 million. However, some of this impact would be offset by additional interest earned on our cash and cash equivalents as a result of the higher rates.

On January 9, 2003, we amended our primary foreign exchange hedging agreement to provide for termination if at any time the amount available under our revolving credit facility becomes less than $2.5 million.

- 47 -

A majority of our revenue, expense and capital purchasing activities are transacted in U.S. dollars. However, as a multinational business, we also conduct certain of these activities through transactions denominated in a variety of other currencies. We use forward foreign currency contracts to hedge firm commitments and reduce our overall exposure to the effects of currency fluctuations on our results of operations and cash flows. Gains and losses on these foreign currency exposures would generally be offset by corresponding losses and gains on the related hedging instruments. This strategy reduces, but does not eliminate, the short-term impact of foreign currency exchange rate movements. For example, changes in exchange rates may affect the foreign currency sales price of our products and can lead to increases or decreases in sales volume to the extent that the sales price of comparable products of our competitors are less or more than the sales price of our products. Our policy prohibits speculation on financial instruments, trading in currencies for which there are no underlying exposures, or entering into trades for any currency to intentionally increases the underlying exposure.

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 the Securities Exchange Act of 1934 (“Exchange Act”) Rules 13a-15(e) and 15d-15(e)). 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 Securities Exchange Act of 1934 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.

Change in Internal Control Over Financial Reporting. There have been no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during the fiscal quarter ended March 30, 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION

Item 1.

Legal Proceedings

Securities Class Action Litigation

During the period July 5, 2001 through July 27, 2001, we were named as a defendant in three shareholder class action lawsuits that were filed in federal court in New York City against us and certain of our former officers, current and former directors and the underwriters for our initial public offering. The lawsuits allege violations of the federal securities laws and have been docketed in the U.S. District Court for the Southern District of New York as: Abrams v. ON Semiconductor Corp., et al. , C.A. No. 01-CV-6114; Breuer v. ON Semiconductor Corp., et al. , C.A. No. 01-CV-6287; and Cohen v. ON Semiconductor Corp., et al. , C.A. No. 01-CV-6942 (“District Court”). On April 19, 2002, the plaintiffs filed a single consolidated amended complaint that supersedes the individual complaints originally filed. The amended complaint alleges, among other things, that the underwriters of our initial public offering improperly required their customers to pay the underwriters’ excessive commissions and to agree to buy additional shares of our common stock in the aftermarket as conditions of receiving shares in our initial public offering. The amended complaint further alleges that these supposed practices of the underwriters should have been disclosed in our initial public offering prospectus and registration statement. The amended complaint alleges violations of both the registration and antifraud provisions of the federal securities laws and seeks unspecified damages. We understand that various other plaintiffs have filed substantially similar class action cases against approximately 300 other publicly-traded companies and their public offering underwriters in New York City, which have all been transferred, along with the case against us, to a single federal district judge for purposes of coordinated case management. We believe that the claims against us are without merit and have defended, and intend to continue to defend, the litigation vigorously. The litigation process is inherently uncertain, however, and we cannot guarantee that the outcome of these claims will be favorable for us.

On July 15, 2002, together with the other issuer defendants, we filed a collective motion to dismiss the consolidated, amended complaints against the issuers on various legal grounds common to all or most of the issuer defendants. The underwriters also filed separate motions to dismiss the claims against them. In addition, the parties have stipulated to the voluntary dismissal without prejudice of our individual former officers and current and former directors who were named as defendants in our litigation, and they are no longer parties to the litigation. On February 19, 2003, the District Court issued its ruling on the motions to dismiss filed by the underwriter and issuer defendants. In that ruling the District Court granted in part and denied in part those motions. As to the claims brought against us under the antifraud provisions of the securities laws, the District Court dismissed all of these claims with prejudice, and refused to allow plaintiffs the opportunity to re-plead these claims. As to the claims brought under the registration provisions of the securities laws, which do not require that intent to defraud be pleaded, the District Court denied the motion to dismiss these claims as to us and as to substantially all of the other issuer defendants as well. The District Court also denied the underwriter defendants’ motion to dismiss in all respects.

In June 2003, upon the determination of a special independent committee of our Board of Directors, we elected to participate in a proposed settlement with the plaintiffs in this litigation. If ultimately approved by the District Court, this proposed settlement would result in the dismissal, with prejudice, of all claims in the litigation against us and against any of the other issuer defendants who elect to participate in the proposed settlement, together with the current or former officers and directors of participating issuers who were named as individual defendants. The proposed settlement does not provide for the resolution of any claims against the underwriter defendants, and the litigation against those defendants is continuing. The proposed settlement provides that the class members in the

- 49 -

class action cases brought against the participating issuer defendants will be guaranteed a recovery of $1.0 billion by the participating issuer defendants. If recoveries totaling less than $1.0 billion are obtained by the class members from the underwriter defendants, the class members will be entitled to recover the difference between $1.0 billion and the aggregate amount of those recoveries from the participating issuer defendants. If recoveries totaling $1.0 billion or more are obtained by the class members from the underwriter defendants, however, the monetary obligations to the class members under the proposed settlement will be satisfied. In addition, we and any other participating issuer defendants will be required to assign to the class members certain claims that we may have against the underwriters of our initial public offerings.

The proposed settlement contemplates that any amounts necessary to fund the settlement or settlement-related expenses would come from participating issuers’ directors and officers’ liability insurance policy proceeds, as opposed to funds of the participating issuer defendants themselves. A participating issuer defendant could be required to contribute to the costs of the settlement if that issuer’s insurance coverage were insufficient to pay that issuer’s allocable share of the settlement costs. We expect that our insurance proceeds will be sufficient for these purposes and that we will not otherwise be required to contribute to the proposed settlement.

On December 5, 2006, the U.S. Court of Appeals for the Second Circuit (“Court of Appeals”) issued a decision in In re Initial Public Offering Securities Litigation that six purported class action lawsuits containing allegations substantially similar to those asserted against the Company may not be certified as class actions due, in part, to the Court of Appeals’ determination that individual issues of reliance and knowledge would predominate over issues common to the proposed classes. On January 8, 2007, the plaintiffs filed a petition seeking rehearing en banc of the Court of Appeals’ decision. On April 6, 2007 the Court of Appeals denied the plaintiffs’ petition for rehearing of the Court of Appeals’ December 5, 2006 ruling but noted that the plaintiffs remain free to ask the District Court to certify a different class which might meet the standards for class certification that the Court of Appeals articulated in its December 5, 2006 decision. Because our proposed settlement with the plaintiffs involves the certification of the case against us as a class action for settlement purposes, the impact of the Court of Appeals’ rulings on the possible settlement of the case cannot now be predicted.

If the proposed settlement described above is not consummated, we intend to continue to defend the litigation vigorously. While we can make no promises or guarantees as to the outcome of these proceedings, we believe that the final result of this action will have no material effect on our consolidated financial condition, results of operations or cash flows.
