ALTERA CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1  Summary of Significant Accounting Policies

Organization and Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Altera
Corporation and its subsidiaries, collectively referred to herein as Altera, we, us, or our, have been prepared by us in accordance with accounting principles generally accepted in the United States of
America (GAAP) for interim financial information. This financial information reflects all adjustments which are, in the opinion of our management, of a normal recurring nature and necessary for a fair statement of the results for the
periods presented. The December 28, 2007 condensed consolidated balance sheet data was derived from our audited consolidated financial statements included in our 2007 Annual Report on Form 10-K, but does not include all disclosures required by
GAAP. The condensed consolidated financial statements include our accounts as well as those of our wholly-owned subsidiaries after elimination of all significant inter-company balances and transactions.

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect
the amounts reported in our condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates and material effects on our consolidated operating results and financial position may result.

Certain reclassifications have been made to prior year financial statements to conform to the current year presentation. Interest expense
was presented as a separate line item in our condensed consolidated statements of income (previously reported as a component of interest and other income, net). Cash flows from our trading securities were reclassified from operating to investing
activities in our condensed consolidated statements of cash flows and purchases and proceeds from sale were presented separately (previously reported on a net basis) based on our analysis of the provisions of SFAS No. 159, The Fair Value Option
for Financial Assets and Financial Liabilities. These reclassifications had no effect on our consolidated operating results or cash flows, as previously reported.

These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 28, 2007 included in our Annual Report on Form 10-K,
as filed on February 25, 2008 with the Securities and Exchange Commission (SEC). The consolidated operating results for the three and six months ended June 27, 2008 are not necessarily indicative of the results to be expected
for any future period.

Significant Accounting Policies

Revenue Recognition

We sell our products to original equipment manufacturers, or OEMs, and to electronic components
distributors who resell these products to OEMs, or their subcontract manufacturers. We sell more than 90% of our products to distributors for subsequent resale to OEMs or their subcontract manufacturers. In almost all cases, sales to distributors
are made under agreements allowing for subsequent price adjustments and returns, and we defer recognition of revenue until the products are resold by the distributor at which time our final net sales price is fixed. At the time of shipment to
distributors, we (1) record a trade receivable at the list selling price since there is a legally enforceable obligation from the distributor to pay us currently for product delivered, (2) relieve inventory for the carrying value of goods
shipped since legal title has passed to the distributor, and (3) record deferred revenue and deferred cost of sales in Deferred income and allowances on sales to distributors in the liability section of our consolidated balance sheets.

Deferred income effectively represents the gross margin on the sale to the distributor; however, the amount of gross margin we recognize
in future periods will be less than the originally recorded deferred income as a result of negotiated price concessions. We sell each item in our product catalog to all of our distributors worldwide at a list price. However, distributors resell our
products to end customers at a very broad range of individually negotiated price points based on a variety of factors, including customer, product, quantity, geography and competitive differentiation. The majority of our distributors resales
are priced at a discount from list price. Often, under these circumstances, we remit back to the distributor a portion of their original purchase price after we validate the distributors resale information, including end customer, device,
quantity and price, against the approved distributor price concession, upon the completion of the resale transaction. To receive price concessions, distributors must submit the price concession claims to Altera for approval within 60 days of the
resale of the product to an end customer. Primarily because of the uncertainty related to the final price, we defer revenue recognition on sales to distributors until our products are sold by the distributor to the end customer, which is when our
price is fixed or

determinable. A substantial portion of the Deferred income and allowances on sales to distributors balance represents a portion of distributors
original purchase price that will be remitted back to the distributor in the future. The wide range and variability of negotiated price concessions granted to distributors does not allow us to accurately estimate the portion of the balance in the
Deferred income and allowances on sales to distributors that will be remitted back to the distributors. Therefore, we do not reduce deferred income by anticipated future price concessions; instead, price concessions are typically recorded against
deferred income and allowances on sales to distributors when incurred, which is generally at the time the distributor sells the product to an end customer. For the six months ended June 27, 2008 and June 29, 2007, total price concessions
earned by distributors were $2.0 billion and $1.5 billion, respectively.

Our distributors have certain return rights, including stock
rotation and return of defective, overstocked, obsolete and discontinued products. Our stock rotation program generally allows distributors to return to Altera product valued at up to 5% of Alteras net billings to the distributor for the six
months prior to the stock rotation. Such rights of return expire upon the products being resold by the distributor to end customers. For the six months ended June 27, 2008 and June 29, 2007, returns from distributors totaled $57.9 million
and $78.2 million, respectively.

For the components of our Deferred income and allowances on sales to distributors account, see Note 2
 Balance Sheet Details.

Revenue from products sold directly to OEMs is recognized upon shipment provided that persuasive evidence of
an arrangement exists, the price is fixed, title has transferred, collection of resulting receivables is reasonably assured, there are no customer acceptance requirements, and there are no remaining significant obligations. We present any taxes
assessed by a governmental authority that are both imposed on and concurrent with our sales on a net basis, excluded from revenues. We record reserves for OEM sales returns and allowances, included in Accounts receivable, net, in the asset section
of our accompanying condensed consolidated balance sheets, for any specific known customer returns or allowances.

Impairment of Deferred Cost of
Sales

We evaluate whether our deferred cost of sales has been impaired based on expected net cash flow to be received for the
deferred item. In assessing the impairment of our deferred cost of sales, we use the guidance provided by Accounting Research Bulletin No. 43, which establishes the lower-of-cost-or-market rule as the guiding principle to be used in assessing
whether cost or a lower estimate of realizable value should be used for inventories. Our deferred cost of sales represents the products shipped from Altera to our distributors. We apply our inventory valuation procedures, including potential
impairment due to excess or obsolescence, to Altera owned inventory and distributor owned inventory. Realization of the deferred cost occurs because we earn revenue in excess of the amount of costs deferred. We do not typically agree to price
discounts with our distributors that would result in us receiving cash in an amount less than the deferred costs of sales. In those rare instances where we have agreed to a price discount below our cost, we write the inventory down to its new cost
basis in accordance with SEC Staff Accounting Bulletin No. 100, Restructuring and Impairment Charges. This results in the amount of deferred cost of sales not exceeding its realizable value.

Derivative Financial Instruments

We account
for derivative instruments and hedging activities under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended (SFAS 133). This statement establishes accounting and reporting standards for
derivative instruments and requires recognition of all derivatives as assets or liabilities in the statement of financial position and measurement of those instruments at fair value. Derivatives that are not designated as hedges for accounting
purposes must be adjusted to fair value through earnings.

We have entered into forward foreign exchange contracts where the counterparty
is a bank. These contracts are intended to reduce our exposure to foreign currency rate changes related to the building construction cost for our new facility in Penang, Malaysia. We do not enter into foreign exchange transactions for trading or
speculative purposes. Although these contracts are or can be effective as hedges from an economic perspective, they do not qualify for hedge accounting under SFAS 133; therefore, they are marked-to-market each period with the change in fair
value recognized in our consolidated statement of income in Interest and other income, net, and classified as either Other current assets or Accrued liabilities in our condensed consolidated balance sheets.

As of June 27, 2008, we had five outstanding forward contracts with a total notional value of $23.8 million to purchase Malaysian Ringgits. The fair
value of the liabilities associated with these forward contracts recorded in our condensed consolidated financial statements was $0.4 million. The forward contracts outstanding as of June 27, 2008 are for terms ranging from 38 to 240 days. The
realized loss from the settlement of the forward contracts did not have a significant impact on our consolidated operating results for the three and six months ended June 27, 2008.

Recent Accounting Pronouncements

In March 2008, the Financial Accounting Standards Board (FASB) issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133
(SFAS 161). This new standard requires enhanced disclosures for derivative instruments, including those used in hedging activities. SFAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008 and
will be applicable to the company in the first quarter of fiscal 2009. We are currently assessing the potential impact that the adoption of SFAS 161 may have on our condensed consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS 157). SFAS 157 defines fair value, establishes a
framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007,
and interim periods of those fiscal years. In February 2008, the FASB released a FASB Staff Position (FSP FAS 157-2Effective Date of FASB Statement No. 157) which delays, to fiscal years beginning after November 15, 2008, the
effective date of SFAS 157 for all non-financial assets and non-financial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). Effective December 29,
2007, we adopted SFAS 157, as it applies to our financial instruments. The adoption of SFAS 157 for financial assets and liabilities did not have a material impact on our condensed consolidated balance sheets, statements of income or cash flows. See
Note 13  Fair Value of Financial Instruments.

Advances to Distributors

On sales to distributors, our payment terms frequently require the distributor to settle amounts owed to us for an amount in excess of their ultimate cost. Our sales price to the distributor may be higher than the
amount that the distributor will ultimately owe us because distributors often negotiate price discounts after purchasing the product from us and such discounts are often significant. It is our practice to apply these negotiated price discounts to
future purchases, requiring the distributor to settle, on a current basis, generally within 30 days, for amounts originally invoiced. This practice has an adverse impact on the working capital of our distributors. As such, we have entered into
business arrangements with certain distributors whereby we advance cash to the distributors to minimize the distributors working capital requirements. These advances are settled in cash at least on a quarterly basis and are the result of
estimates based on the amount of ending inventory as reported by the distributor multiplied by a negotiated percentage. Such advances have no impact on our revenue recognition or our condensed consolidated statements of income and are a component of
the Deferred income and allowances on sales to distributors on our condensed consolidated balance sheets. We continuously process discounts taken by distributors against our deferred income and allowances on sales to distributors. We adjust the
recorded amount of the distributor advances based on cash settlements at the end of each quarter. These advances are set forth in binding legal agreements and are unsecured, bear no interest and are due upon demand. The agreements governing these
advances can be cancelled by us at any time. Such advances totaled $135.7 million at June 27, 2008 and $118.7 million at December 28, 2007.

We also enter into arrangements that, in substance, finance distributors accounts receivable and inventory. The amounts advanced are classified as Other current assets in our condensed consolidated balance
sheets and totaled $63.3 million at June 27, 2008 and $54.8 million at December 28, 2007. These arrangements are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand.

Accumulated other comprehensive loss presented in the accompanying condensed consolidated balance
sheets consists of the accumulated unrealized gain/loss on investments, net of tax, and unamortized balance of gain/loss on our retiree medical plan, net of tax.

Note 4  Income Per Share

In accordance with Statement of Financial Accounting Standards No. 128, Earnings Per
Share (SFAS 128), we compute basic income per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. To determine diluted share count, we apply the
treasury stock method to determine the dilutive effect of outstanding stock option shares, restricted stock units, and ESPP shares. Our application of the treasury stock method includes as assumed proceeds the average unamortized stock-based
compensation expense for the period and the impact of the pro forma deferred tax benefit or cost associated with stock-based compensation expense.

In applying the treasury stock method, we excluded 19.4 million and 26.6 million stock option shares for the three and six months ended June 27, 2008, respectively, and 21.8 million and 23.1 million stock option
shares for the three and six months ended June 29, 2007, respectively, because their effect was anti-dilutive. While these stock option shares are currently anti-dilutive, they could be dilutive in the future. All restricted stock units
outstanding as of June 27, 2008 were in-the-money and were included in our treasury stock method calculation. A reconciliation of basic and diluted income per share is presented below:

Our total borrowings under the Facility at June 27, 2008 were $500
million. Borrowings under this Facility bear interest at either a Eurodollar rate (LIBOR) or a Prime rate, at our option, plus an applicable margin based upon certain financial ratios, determined and payable quarterly. The interest rate
as of June 27, 2008 was LIBOR plus 0.35%. In addition, we pay a facility fee on the entire Facility. This facility fee varies with certain financial ratios and was 0.10% as of June 27, 2008. The principal amount of borrowings, together
with accrued interest, is due on the maturity date in August 2012. As of June 27, 2008, $250 million is available under this Facility.

The terms of this Facility require compliance with certain financial covenants that require us to
maintain certain financial ratios related to interest coverage and financial leverage. As of June 27, 2008 we were in compliance with all such covenants.

Note 7  Commitments and Contingencies

Indemnification and Product Warranty

We indemnify certain customers, distributors, suppliers, and subcontractors for attorney fees, and damages and costs awarded against these parties in
certain circumstances in which our products are alleged to infringe third party intellectual property rights including patents, trade secrets, trademarks, or copyrights. We cannot estimate the amount of potential future payments, if any, that we
might be required to make as a result of these agreements. To date, we have not paid any claim or been required to defend any action related to our indemnification obligations, and accordingly, we have not accrued any amounts for such
indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations.

We generally
warrant our devices for one year, against defects in materials, workmanship and non-conformance to our specifications. We accrue for known warranty issues if a loss is probable and can be reasonably estimated, and accrue for estimated but
unidentified issues based on historical activity. If there is a material increase in customer claims compared with our historical experience or if the costs of servicing warranty claims are greater than expected, we may record a charge against cost
of sales.

The following table summarizes the activity related to our product warranty liability for the six months ended June 27,
2008 and June 29, 2007, which is included in Accrued liabilities in our condensed consolidated balance sheets. Activity for the three months ended June 27, 2008 and June 29, 2007 was not significant.

Purchase Obligations

We depend entirely upon subcontractors to manufacture our silicon wafers and provide assembly and test services. Due to lengthy subcontractor lead times, we must order these materials and services from these
subcontractors well in advance, and we are obligated to pay for the materials and services once they are completed. As of June 27, 2008, we had approximately $121.9 million of outstanding purchase commitments to such subcontractors. We expect
to receive and pay for these materials and services within the next four to six months.

Note 9  Stock-Based Compensation

Stock-Based Compensation Plans

2005 Equity Incentive Plan

Our equity incentive program is a broad-based, long-term retention program intended to attract, motivate, and retain talented employees as well as align
stockholder and employee interests. On May 10, 2005, our stockholders approved Alteras 2005 Equity Incentive Plan (the 2005 Plan). The 2005 Plan replaced our 1996 Stock Option Plan (the 1996 Plan) and our 1998
Director Stock Option Plan (the 1998 Plan) (together, the 1996 Plan and the 1998 Plan are referred to as Prior Plans) and is now Alteras only plan for providing stock-based incentive compensation (awards) to
both our eligible employees and non-employee directors. Awards that may be granted under the 2005 Plan include non-qualified and incentive stock options, restricted stock units (RSUs), restricted stock awards, stock appreciation rights,
and stock bonus awards. To date, we have granted both options and RSUs under the 2005 Plan. The majority of awards of stock options and RSUs granted under the 2005 Plan vests over four years. Stock options granted under the 2005 Plan have a maximum
contractual term of ten years. As of June 27, 2008, the 2005 Plan had a total of 28.5 million shares reserved for future issuance, of which 17.9 million shares were available for future grants.

A summary of our RSU activity for the six months ended June 27, 2008 and information regarding RSUs outstanding and expected to vest as of
June 27, 2008 is as follows:

from the employee stock purchase plan (ESPP), and the vesting of RSUs. The net tax benefit from such stock related activities was $7.5 million and $17.3 million for the six months ended June 27, 2008 and June 29, 2007,
respectively.

As of June 27, 2008, 3.0 million shares were available for future issuance under the ESPP. We sold 532,634 shares
of common stock under the ESPP at a price of $16.39 for the six months ended June 27, 2008 and 579,064 shares of common stock at a price of $15.07 for the six months ended June 29, 2007.

As at June 27, 2008, unamortized stock-based compensation expense related to the outstanding
unvested stock options, RSUs, and ESPP shares that are expected to vest was approximately $94.0 million. This unamortized stock-based compensation expense is expected to be recognized over a weighted average period of approximately 2.6 years. No
stock based compensation was capitalized during the six months ended June 27, 2008.

Stock Options and ESPP Shares

We estimate the fair value of stock options and ESPP shares on the date of grant using the Black-Scholes option-pricing model. The assumptions used to
estimate the fair value of stock options and ESPP shares granted during the three and six months ended June 27, 2008 and June 29, 2007 were as follows:

Note 10  Income Taxes

Our effective tax rate reflects the impact of a significant amount of our earnings being taxed in foreign jurisdictions at rates below the U.S. statutory tax rate. Our effective tax rate for the three and six months
ended June 27, 2008 was 16.5%, compared with 14% for the three and six months ended June 29, 2007. The increase in our effective tax rate was primarily due to the expiration of the federal research and development credit.

We file U.S. federal income tax returns as well as income tax returns in various states and foreign jurisdictions. The Internal Revenue Service
(IRS) has completed field examinations of our tax returns for fiscal years 2002 through 2004 and has issued a notice of proposed adjustment seeking additional taxes of approximately $34.5 million (excluding interest) for those years. We
are contesting through the administrative process the IRS claims regarding our 2002 through 2004 tax years. The IRS has notified us that it intends to examine our tax returns for fiscal years 2005 and 2006. Other significant jurisdictions in which
we may be subject to examination for fiscal years 2002 forward include Hong Kong, Ireland, Japan, and the state of California. As mentioned below, we believe we have made adequate tax payments and/or accrued adequate amounts such that the outcome of
these audits will have no material adverse effects on our consolidated operating results.

We maintain reserves for uncertain tax benefits
within our income taxes payable account. These reserves involve considerable judgment and estimation and are monitored by management based on the best information available, including changes in tax regulations, the outcome of relevant court cases
and other information. We are currently under examination by various taxing authorities. Although the outcome of any tax audit is uncertain, we believe we have adequately provided in our condensed consolidated financial statements for any additional
taxes that we may be required to pay as a result of such examinations. If the payment ultimately proves to be unnecessary, the reversal of these tax liabilities would result in tax benefits being recognized in the period we determine such
liabilities are no longer necessary. However, if an ultimate tax assessment exceeds our estimate of tax liabilities, an additional tax provision will be recorded. The impact of such adjustments in our tax accounts could have a material impact on our
consolidated operating results and cash flows in future periods.

As of June 27, 2008, we had $183.0 million of unrecognized tax
benefits of which $17.6 million is expected to be settled in the next 12 months. On December 28, 2007, we had $169.7 million of unrecognized tax benefits of which $13.6 million was expected to be settled in the next 12 months.

We recognize interest and penalties related to uncertain tax positions in our income tax provision. On December 28, 2007, we had approximately $28.1
million accrued for the payment of interest and penalties. As of June 27, 2008, we had approximately $34.5 million accrued for the payment of interest and penalties related to uncertain tax positions.

Note 11  Nonqualified Deferred Compensation Plan

We allow our U.S.-based officers, director-level employees, and members of our board of directors to defer a portion of their compensation under the Altera Corporation Nonqualified Deferred Compensation Plan (NQDC Plan). Our
Retirement Plans Committee administers the NQDC Plan. On June 27, 2008, there were approximately 121 participants in the NQDC

Plan who self-direct their investments in the NQDC Plan, subject to certain limitations. In the event we become insolvent, NQDC Plan assets are subject to
the claims of our general creditors. Since the inception of the NQDC Plan, we have not made any contributions to the NQDC Plan and we have no commitments to do so in the future. There are no NQDC Plan provisions that provide for any guarantees or
minimum return on investments. NQDC Plan participants are prohibited from investing in Altera common stock. On June 27, 2008, NQDC Plan assets and obligations were $68.3 million. On December 28, 2007, NQDC Plan assets and obligations were
$74.8 million.

Investment income (loss) earned by the NQDC Plan is recorded within interest and other income, net, in our condensed
consolidated statements of income. The investment income (loss) also represents an increase (decrease) in the future payout to employees and is treated as current period compensation expense. Income (loss) earned by the NQDC Plan does not impact,
nor has it ever impacted, our income before income taxes, net income, or cash balances. The following table presents the net investment gains (loss) and corresponding compensation expense for the three and six months ended June 27, 2008, and
June 29, 2007.

Note 12  Restructuring Charges

During the fourth quarter of fiscal 2007, we announced a restructuring of our operations in order to lower our overall cost structure and enhance near and
long term profitability of the company. The restructuring plan included elimination of 67 jobs and consolidation of excess facilities resulting in restructuring of our office leases in San Diego and Santa Cruz, California; Ottawa, Canada; and Hong
Kong. The following table summarizes the significant activity within, and components of, our restructuring obligations as of June 27, 2008:

Note 13  Fair Value of Financial Instruments

We adopted SFAS 157 effective December 29, 2007 for financial assets and liabilities measured on a recurring basis. SFAS 157 clarifies that fair
value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be
determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, SFAS 157 establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair
value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which
there is little or no market data, which require us to develop our own assumptions. This hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring
basis, we measure certain financial assets and liabilities at fair value, which consist of our marketable securities and foreign currency contracts.

The following table summarizes the valuation of our short-term investments and the financial instruments which were determined by using the following inputs as of June 27, 2008:

Our cash and investment instruments are classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market
prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The types of instruments valued based on quoted market prices in active markets include money market securities, exchange traded stocks
and open-end mutual funds. Such instruments are generally classified within Level 1 of the fair value hierarchy.

The types of instruments
valued based on other observable inputs include bank commercial deposits, corporate commercial paper and municipal obligations. Such instruments are generally classified within Level 2 of the fair value hierarchy.

The principal market where we execute our foreign currency contracts is the retail market in an over-the-counter environment with a relatively high level
of price transparency. The market participants usually are large commercial and investment banks. Our foreign currency contracts valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not
involve management judgment. These contracts are typically classified within Level 2 of the fair value hierarchy.

Note 14  Legal Proceedings

We have been named as a party to several lawsuits concerning our historical stock option practices and related accounting and reporting.

In May and July 2006, we were notified that three shareholder derivative lawsuits had been filed in the Superior Court of the State of
California, County of Santa Clara, by persons identifying themselves as Altera shareholders and purporting to act on behalf of Altera, naming Altera Corporation as a nominal defendant and naming some of our current and former officers and directors
as defendants. On July 12, 2006, one of these derivative actions was voluntarily dismissed by the plaintiff shareholder. The remaining two derivative lawsuits pending in Santa Clara Superior Court were consolidated into a

single action on September 5, 2006. Plaintiffs filed a second amended consolidated complaint on December 15, 2006. On January 30, 2007, Altera
and the defendants filed a motion to stay this action pending resolution of the federal derivative action (discussed below). There have been no material developments in this action since January 30, 2007.

The consolidated California state court action names Altera Corporation as a nominal defendant and the following current and former Altera officers and
directors as defendants: John P. Daane, Nathan M. Sarkisian, Denis M. Berlan, Robert W. Reed, Robert J. Finocchio, Jr., Kevin McGarity, Paul Newhagen, William E. Terry, Susan Wang, Charles M. Clough, Rodney Smith, Michael B. Jacobs, Katherine E.
Schuelke, Deborah Reiman, Michael J. Ellison, C. Wendell Bergere, Clive McCarthy, and Peter Smyth. Plaintiffs assert claims against these individual defendants for breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate
assets, unjust enrichment, violations of California Corporation Code sections 25402 and 25403, breach of fiduciary duty for insider selling and misappropriation of information, rescission, constructive trust, accounting, and deceit. Plaintiffs
claims concern the granting of stock options by Altera between 1994 and 2001 and the alleged filing of false and misleading financial statements between 1994 and 2006. All of these claims are asserted derivatively on behalf of Altera. Plaintiffs
seek, among other relief, an indeterminate amount of damages from the individual defendants and a judgment directing Altera to reform its corporate governance practices.

During the months of May, June, and July 2006, four other derivative lawsuits were filed by purported Altera shareholders, on behalf of Altera, in the United States District Court for the Northern District of
California. On August 8, 2006, these actions were consolidated, and the plaintiffs filed a consolidated complaint on November 30, 2006. During the third quarter of 2007, Altera moved to dismiss this action for lack of standing. The court
granted Alteras motion in May 2008. The plaintiffs filed a first amended consolidated complaint on June 16, 2008, which Altera moved to dismiss for lack of standing on July 15, 2008.

Among the defendants named in these derivative actions are Altera Corporation as a nominal defendant and the following current and former officers and
directors of Altera: John P. Daane, Nathan M. Sarkisian, Denis M. Berlan, Robert W. Reed, Robert J. Finocchio, Jr., Kevin McGarity, Paul Newhagen, William E. Terry, Susan Wang, Charles M. Clough, Rodney Smith, Michael B. Jacobs, Katherine E.
Schuelke, John R. Fitzhenry, Deborah Reiman, Michael J. Ellison, C. Wendell Bergere, Clive McCarthy, and Peter Smyth. The first amended consolidated complaint includes claims for violations of Sections 10(b), 14(a), and 20(a) of the Securities
Exchange Act of 1934, breach of fiduciary duty, corporate waste, gross mismanagement, unjust enrichment, abuse of control, insider selling and misappropriation of information, rescission, accounting, and violations of California Corporation Code
sections 25402 and 25502.5. Plaintiffs claims concern the granting of stock options by Altera between 1995 and 2001 and the alleged filing of false and misleading financial statements between 1996 and 2005.

Note 15  Subsequent Event

On July 14,
2008, our board of directors declared a quarterly cash dividend of $0.05 per common share which is payable on September 2, 2008 to shareholders of record on August 11, 2008.

The following Managements Discussion and Analysis of Financial Condition and Results of Operations, as well as information contained in the risk
factors described in Item 1A of this report and elsewhere in this report, contains forward-looking statements, which are provided under the safe harbor protection of the Private Securities Litigation Reform Act of 1995.
Forward-looking statements are generally written in the future tense and/or are preceded by words such as will, may, should, could, expect, suggest, believe,
anticipate, intend, plan, or other similar words. Forward-looking statements include statements regarding (1) our gross margins and factors that affect gross margins; (2) trends in our future sales;
(3) our research and development expenditures and efforts; (4) our capital expenditures; (5) the impact of accounting pronouncements, (6) our provision for tax liabilities and other critical accounting estimates.

Forward-looking statements are not guarantees of future performance and involve risks and uncertainties. The forward-looking statements contained
in this report are based on information that is currently available to us and expectations and assumptions that we deemed reasonable at the time the statements were made. We do not undertake any obligation to update any forward-looking statements in
this report or in any of our other communications, except as required by law. All such forward-looking statements should be read as of the time the statements were made and with the recognition that these forward-looking statements may not be
complete or accurate at a later date.

Many factors may cause actual results to differ materially from those expressed or implied by
the forward-looking statements contained in this report. These factors include, but are not limited to, those risks described in Part II Item 1A of this report and those risks described under Managements Discussion and Analysis of
Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 28, 2007.

CRITICAL
ACCOUNTING ESTIMATES

The preparation of our condensed consolidated financial statements and related disclosures in conformity with
accounting principles generally accepted in the United States requires our management to make judgments and estimates that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Our management believes
that we consistently apply these judgments and estimates and the condensed consolidated financial statements and accompanying notes fairly represent all periods presented. However, any differences between these judgments and estimates and actual
results could have a material impact on our condensed consolidated statement of income and financial position. Critical accounting estimates, as defined by the Securities and Exchange Commission (SEC), are those that are most important to the
portrayal of our consolidated financial condition and results of operations and require our managements most difficult and subjective judgments and estimates of matters that are inherently uncertain. Our critical accounting estimates include
those regarding (1) revenue recognition, (2) valuation of inventories, (3) income taxes, and (4) stock-based compensation.

Revenue Recognition

We sell our products to original equipment manufacturers, or OEMs, and to electronic components
distributors who resell these products to OEMs, or their subcontract manufacturers. We sell more than 90% of our products to distributors for subsequent resale to OEMs or their subcontract manufacturers. In almost all cases, sales to distributors
are made under agreements allowing for subsequent price adjustments and returns, and we defer recognition of revenue until the products are resold by the distributor. Our revenue reporting is highly dependent on receiving pertinent and accurate data
from our distributors in a timely fashion. Distributors provide us with periodic data regarding the product, price, quantity, and end customer when products are resold as well as the quantities of our products they still have in stock. Because the
data set is so large and because there may be errors in the reported data, we must use estimates and apply judgments to reconcile distributors reported inventories to their activities. This reconciliation process requires us to estimate the
amount of in-transit shipments (net of in-transit returns) to our distributors. In-transit days can significantly vary among geographies and individual distributors. We also apply judgment when estimating the total value of price concessions earned
by our distributors but not claimed by the end of the reporting period. This is because there is a time lag between the price concessions earned and claimed by the distributors for any underlying resale of products. Any error in our judgment could
lead to inaccurate reporting of our revenues, deferred income and allowances on sales to distributors, and net income.

For a discussion of
our other critical accounting estimates, see Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations  Critical Accounting Estimates in our Annual Report on Form 10-K for the year ended
December 28, 2007.

RESULTS OF OPERATIONS

Sales Overview

We design, manufacture, and market high-performance,
high-density programmable logic devices, or PLDs; HardCopy® ASIC devices; pre-defined software design building blocks known as intellectual property cores, or IP cores; and associated
development tools.

We classify our products into three categories: New, Mainstream, and Mature and Other Products as follows:



| |  |  | New Products include the Stratix® II, Stratix II GX, Stratix
III, Arria GX, Cyclone® II, Cyclone III, MAX® II, HardCopy, and Hardcopy II devices;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mainstream Products include the Stratix, Stratix GX, Cyclone, and MAX 3000A devices; and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | Mature and Other Products include the Classic, MAX 7000, MAX 7000A, MAX 7000B, MAX 7000S, MAX 9000, FLEX® series, APEX series, Mercury, Excalibur, configuration and other devices, intellectual property cores, and software and other tools.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The product categories above have been constructed to approximate the relative life cycle stages of the companys products. The product
categories compositions are adjusted approximately every two to three years. New Products are primarily comprised of the companys most advanced products. Customers select these products for their latest generation of electronic systems.
Demand is generally driven by prototyping and production needs. Mainstream Products are somewhat older products which are generally no longer design-win vehicles. Demand is driven by customers later stage production-based needs. Mature
Products are yet older products with demand generated by the oldest customer systems still in production. This category also includes sales of software, intellectual property, and other miscellaneous devices.

Our net sales of $359.9 million for the three months ended June 27, 2008 increased by $40.2 million, or 13%, over our net sales of $319.7 million
for the three months ended June 29, 2007. Our net sales of $695.9 million for the six months ended June 27, 2008 increased by $71.3 million, or 11%, over our net sales of $624.6 million for the six months ended June 29, 2007. The
year-over-year increase in net sales was due to growth in sales of our New Products, led by higher sales of our Stratix II, Stratix II GX, Cyclone II, Cyclone III and Max II families.

Sales for the three and six months ended June 27, 2008 were driven by four primary business dynamics:



| |  |  | Strong double-digit growth in New Products, partially offset by declines in the Mainstream and Mature Product categories;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | PLD expansion into new applications across all four major market segments, enabled by advances in technology and performance;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | Increasing programmable content in electronic systems and displacement of alternative products; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | Rising demand in emerging markets
| | - |  | ---------------------------------

In
the three and six months ended June 27, 2008, three of our four major market segments advanced versus the comparable period in 2007, primarily as a result of strong traction in ASIC and ASSP replacement. Additionally, prior year sales were
lower due to wide-spread customer inventory reduction programs. Sales in the Computer and Storage segment declined for the three months ended June 27, 2008 versus the comparable period in 2007, primarily as a result of customers ramping down
older generation programs.

Sales by Market Segment

The following market segment data is derived from data that is provided to us by our distributors and end customers. With a broad base of customers, who in some cases manufacture end products spanning multiple market
segments, the assignment of revenue to a market segment requires the use of estimates, judgment, and extrapolation. As such, actual results may differ from those reported.

Sales by market segment, as a percentage of total sales, as well as year-over-year and sequential growth or decline for the periods indicated, were as

Sales of FPGAs and CPLDs

Our PLDs consist of field-programmable gate arrays, or FPGAs, and complex programmable logic devices, or CPLDs. FPGAs consist of our Stratix, Cyclone, APEX, FLEX, and ACEX series, as well as our Excalibur and Mercury
families. CPLDs consist of our MAX, MAX II, and Classic families. Our other products consist of HardCopy, HardCopy II and other masked programmed logic devices, configuration devices, software and other tools and IP cores (collectively, Other
Products). Sales of Other Products for the three months ended June 27, 2008 decreased by 15%, when compared to the three months ended June 29, 2007. This decrease was primarily attributable to customers ramping down older generation
programs. Our sales of FPGAs and CPLDs, and Other Products as a percentage of total sales, as well as year-over-year and sequential growth or decline for the periods indicated, were as follows:

Price Concessions and Product Returns from Distributors

We sell each item in our product catalog to all of our distributors worldwide at a list price. However, distributors resell our products to end customers
at a very broad range of individually negotiated price points based on a variety of factors, including customer, product, quantity, geography and competitive differentiation. The majority of our distributors sales to their customers are priced
at a discount from our list price. Often, under these circumstances, we remit back to the distributor a portion of their original purchase price after the resale transaction is completed and we validate the distributors resale information,
including end customer, device, quantity and price, against the approved distributor price concession. To receive price concessions, distributors must submit the price concession claims to us for approval within 60 days of the resale of the product
to an end customer. Primarily because of the uncertainty related to the final price, we defer revenue recognition on sales to distributors until our products are sold from the distributor to the end customer, which is when our price is fixed or
determinable. Accordingly, these pricing uncertainties impact our results of operations, liquidity and capital resources since the final price earned and cash received for our products varies based on the extent of high volume of product purchased
by an end customer and individual competitive situation. For the six months ended June 27, 2008 and June 29, 2007, total price concessions earned by distributors were $2.0 billion and $1.5 billion, respectively. Price concessions represent
71% and 70% of our list price for the six months ended June 27, 2008 and June 29, 2007, respectively.

Our distributors have
certain return rights, including stock rotation and return of defective, overstocked, obsolete and discontinued products. Our stock rotation program generally allows distributors to return to Altera product up to 5% of the value of Alteras net
billings to the relevant distributor for the six months prior to the stock rotation. Such rights of return expire upon the products being resold by the distributor to end customers. For the six months ended June 27, 2008 and June 29, 2007,
returns from distributors totaled $57.9 million and $78.2 million, respectively.

2008 compared to the same period in the prior year. Gross margin percentages increased by 1 point to 66.2% for the six months ended June 27, 2008 compared to the same period in the prior year. Gross margin rates are heavily influenced by both
market segment mix and the timing of material cost improvements. While these variables will continue to fluctuate on a quarterly basis, the company is targeting a 65% gross margin over the long term. We believe the 65% gross margin target affords
the company the right mix of growth opportunities across all served markets.

Stock-based compensation expense recognized during the three
and six months ended June 27, 2008 and June 29, 2007 did not have a significant impact on our gross margin.

Research and development expenses include expenditures for compensation and benefits, stock-based
compensation expense, masks, prototype wafers, depreciation and amortization. These expenditures are for the design of new PLD and ASIC families, the development of process technologies, new package technology, software to support new products and
design environments, and IP cores. Also included in research and development expenses is the mark-to-market impact of the Altera Non-Qualified Deferred Compensation Plan (NQDC Plan), which consisted of a $0.5 million expense and $2.3
million benefit for the three and six months ended June 27, 2008, as compared to a $1.6 million and $2.1 million expense for the same periods in 2007. This mark-to-market impact of the NQDC Plan is completely offset in interest and other
income, net.

Research and development expenses for the three months ended June 27, 2008 increased by $1.1 million, or 2%, when
compared to the three months ended June 29, 2007. This increase was attributable to a $3.0 million increase in compensation and benefits, a $2.0 million increase in spending on prototypes, and a $1.2 million increase in stock-based
compensation. These increases were substantially offset by a $5.6 million decrease in spending on masks and wafers.

Research and
development expenses for the six months ended June 27, 2008 increased by $0.9 million, or 1%, when compared to the six months ended June 29, 2007. This increase was attributable to a $6.3 million increase in compensation and benefits, a
$2.8 million increase in spending on prototypes, and a $1.0 million increase in stock-based compensation expense. These increases were substantially offset by the mark-to-market benefit of the NQDC Plan of $4.4 million and a $5.3 million decrease in
spending on masks and wafers.

We will continue to make significant investments in
the development of new products and focus our efforts on the development of new programmable logic devices that use advanced semiconductor wafer fabrication processes, as well as related development software. We are currently investing in the
development of future silicon products, as well as our Quartus ® II software, our library of IP cores, and other future products.

Selling, general, and administrative expenses primarily include compensation and benefits related
to sales, marketing, and administrative personnel as well as stock-based compensation expense, commissions and incentives, depreciation, legal, advertising, facilities, and travel expenses. Also included in selling, general, and administrative
expenses is the mark-to-market impact of our NQDC Plan, which consisted of a $0.2 million and $2.3 million benefit for the three and six months ended June 27, 2008, as compared to a $1.4 million and $2.0 million expense for the same periods in
2007. The mark-to-market impact of the NQDC Plan is completely offset in interest and other income, net.

Selling, general, and
administrative expenses for the three months ended June 27, 2008 decreased by $3.9 million, or 6%, when compared to the three months ended June 29, 2007. This decrease was primarily due to a $0.9 decrease in compensation and benefits, a
$1.8 million decrease in stock-based compensation expense as a result of headcount reductions, and a $1.6 decrease in the mark-to-market impact of our NQDC Plan noted above.

Selling, general, and administrative expenses for the six months ended June 27, 2008 decreased by $14.7 million, or 10%, when compared to the six
months ended June 29, 2007. This decrease was primarily due to our ongoing efforts to increase efficiency and reduce costs by reducing headcount, consulting services and stock-based compensation expense. Selling, general, and administrative
expenses for the six months ended June 27, 2008 were also favorably affected by the mark-to-market impact of our NQDC Plan noted above. Compensation and benefits for the six months ended June 27, 2008 decreased by $2.6 million due to
headcount reductions, as compared to the same period in 2007. Consulting costs for the six months ended June 27, 2008 decreased by $3.0 million, as compared to the same period in 2007. The decrease in consulting costs was primarily due to the
absence in 2008 of costs incurred in 2007 related to the implementation of our enterprise resource planning (ERP) system. Stock-based compensation expense decreased by $2.5 million for the six months ended June 27, 2008 as compared
to the same period in 2007.

Interest and other income, net, consists mainly of interest income generated from investments in
high-quality fixed income securities, as well as the mark-to-market impact of our NQDC Plan. The year-over-year decrease in interest and other income, net, for the three and six months ended June 27, 2008 was driven primarily by a decrease in
interest income as a result of lower interest rates and cash balances, and the mark-to-market impact of our NQDC Plan.

During the three
months ended June 27, 2008, the NQDC Plan experienced a net investment gain of $0.3 million. This gain resulted in a $0.3 million favorable impact to other income and an unfavorable impact to operating expenses, increasing research and
development expenses by $0.5 million and decreasing selling, general and administrative expenses by $0.2 million. During the six months ended June 27, 2008, the NQDC Plan experienced a net investment loss of $4.7 million. This loss resulted in
a $4.7 million unfavorable impact to other income and a favorable impact to operating expenses, decreasing compensation expense by $4.7 million.

##### Table of Contents

During the three months ended June 29, 2007, the NQDC Plan experienced a net investment gain of $3.0
million. This gain resulted in a $3.0 million favorable impact to other income and an unfavorable impact to operating expenses, increasing research and development expenses by $1.6 million and increasing selling, general and administrative expenses
by $1.4 million. During the six months ended June 29, 2007, the NQDC Plan experienced a net investment gain of $4.2 million. This gain resulted in a $4.2 million favorable impact to other income and an unfavorable impact to operating expenses,
increasing compensation expense by $4.2 million.

Interest expense for the three and six months ended June 27, 2008 increased compared
to the same periods in 2007 as a result of the outstanding borrowings under our long term credit facility.

Provision for Income Taxes

Our effective tax rate for the three and six months ended June 27, 2008 was 16.5%, compared with 14% for the three and six months ended
June 29, 2007. The increase in our effective tax rate was primarily due to the expiration of the federal research and development credit. Our effective tax rate reflects the impact of significant amounts of our earnings being taxed in foreign
jurisdictions at rates below the U.S. statutory rate.

As of June 27, 2008, we had a liability under FIN 48 for unrecognized tax
benefits totaling $183.0 million, of which $17.6 million is expected to be paid in the next 12 months. For the remaining liability, we are unable to make a reasonably reliable estimate as to when cash settlement with a taxing authority will occur.

Liquidity

We derive our liquidity and capital resources primarily from our cash flows from operations and long-term credit facility. We continue to generate positive operating cash flows. We currently use cash from operations
and from our credit facility for repurchases of our common stock, cash dividends, and capital expenditures. Based on past performance and current expectations, we believe our current available sources of funds including cash, cash equivalents,
investments, and credit facility, plus anticipated cash generated from operations, will be adequate to finance our operations, stock repurchases, cash dividends and capital expenditures for at least the next year.

On August 31, 2007, we entered into a five-year $750 million unsecured revolving credit facility (the Facility). As of June 27,
2008, we have borrowed $500 million using this credit facility. We classified the credit facility as long term as of June 27, 2008. The interest rate as of June 27, 2008 was LIBOR plus 0.35%. In addition, we pay a facility fee on the
entire Facility. This facility fee varies with certain financial ratios and was 0.10% as of June 27, 2008. The terms of this credit facility require compliance with certain financial and non-financial covenants. Financial covenants require us
to maintain certain financial ratios related to interest coverage and financial leverage. As of June 27, 2008, we were in compliance with all such covenants.

##### Table of Contents

During the six months ended June 27, 2008, we spent $276.7 million to repurchase shares of our
common stock, compared to $461.6 million for the six months ended June 29, 2007. We spent $11.1 million on capital expenditures during the six months ended June 27, 2008, compared to $18.9 million in the six months ended June 29,
2007. Capital expenditures declined due to non-recurring expenditures associated with the installation in 2007 of our ERP system. We plan to spend approximately $22.0 million for the construction of a building adjacent to our current facility in
Penang, Malaysia. Completion of the building is expected during the first quarter of fiscal 2009.

We also plan to use a portion of our
available capital to repurchase shares of our common stock.

During the six months ended June 27, 2008, we paid out cash dividends of
$27.4 million compared to $14.2 million for the six months ended June 29, 2007. Our dividend policy could be impacted in the future by, among other items, future changes in our cash flows from operations and our capital spending needs such as
those relating to research and development, investments and acquisitions, common stock repurchases, and other strategic investments.

Cash Flows

Our positive cash flows from operating activities for the six months ended June 27, 2008 were primarily attributable to net income of
$181.9 million, adjusted for non-cash items including stock-based compensation expense of $24.2 million and depreciation and amortization of $15.2 million. Significant non-cash working capital changes included a $55.2 million increase in Deferred
income and allowances on sales to distributors, substantially offset by a $58.4 million increase in Accounts receivable, net.

As discussed
in Note 1 to our condensed consolidated financial statements as of and for the six months ended June 27, 2008, sales to distributors are primarily made under agreements allowing for subsequent price adjustments and returns, and we defer
recognition of revenue until the products are resold by the distributor. At the time of shipment to distributors, we (1) record a trade receivable at the list selling price since there is a legally enforceable obligation from the distributor to
pay us currently for product delivered, (2) relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor, and (3) record deferred revenue and deferred cost of sales in Deferred income and
allowances on sales to distributors in the liability section of our consolidated balance sheets. Accordingly, increases in accounts receivable, associated with higher billings are generally offset by corresponding increases in deferred income and
allowances on sales to distributors. However, timing differences between gross billings, discounts earned, collections, and revenue recognition may result in temporary interruption to the normal relationship between these two accounts.

The $58.4 million increase in Accounts receivable, net, principally relates to increased shipments to distributors and OEMs associated with an upward
trend in demand for our products in June 2008 compared to December 2007. Consistent with the dynamics described above, Deferred income and allowances on sales to distributors increased by $55.2 million during the six months ended June 27, 2008,
based on our practice of deferring such amounts until products are resold by the distributor. The net increase of $3.2 million, representing a use of cash in our condensed consolidated statement of cash flows for the six months ended June 27,
2008, relates to factors associated with timing, as described above. Activity affecting Deferred income and allowances on sales to distributors for the six months ended June 27, 2008 is presented in Note 2 to the condensed consolidated
financial statements presented herewith.

Cash provided by investing activities for the six months ended June 27, 2008 primarily
consisted of proceeds from the maturities and sales of available-for-sale investments of $81.5 million and sale of land for $9.1 million, partially offset by purchases of property and equipment of $11.1 million.

Cash used for financing activities for the six months ended June 27, 2008 primarily consisted of repurchases of our common stock of $276.7 million
and a cash dividend payment of $27.4 million, partially offset by proceeds of our long-term credit facility of $250.0 million and $34.9 million from the issuance of common stock to employees through stock option exercises.

Purchase Obligations; Commitments and Contingencies

We depend entirely upon subcontractors to manufacture our silicon wafers and provide assembly and test services. Due to lengthy subcontractor lead times,
we must order these materials and services from these subcontractors well in advance, and we are obligated to pay for the materials and services once they are completed. As of June 27, 2008, we had approximately $121.9 million of outstanding
purchase commitments to such subcontractors. We expect to receive and pay for these materials and services within the next four to six months.

We also lease facilities under non-cancelable lease agreements expiring at various times through 2015. There have been no material changes to our operating lease obligations since our 2007 fiscal year end. The balance of our capital lease
obligations included in our liabilities was $11.8 million as of June 27, 2008 and $1.3 million as of December 28, 2007. Amortization expense related to assets acquired under capital leases was $2.1 million for the six months ended
June 27, 2008.

In addition to these lease and purchase obligations, in the normal course of business, we enter into a variety of
agreements and financial commitments. It is not possible to predict the maximum potential amount of future payments under these agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each
particular agreement. Historically, payments pursuant to such agreements have not been material. We believe that any future payments required pursuant to such agreements would not be material to our consolidated financial position or operating
results.

As at June 27, 2008 we had a liability for unrecognized tax benefits in the accompanying condensed consolidated balance
sheets totaling $183.0 million, of which $17.6 million is expected to be paid in the next 12 months. For the remaining liability, the company is unable to make a reasonably reliable estimate as to when cash settlement with a taxing authority will
occur.

Impact of Currency Translation and Inflation

Although we purchase the majority of our materials and services in U.S. dollars and sell our products to OEMs and distributors in U.S. dollars, we do have international operations and are, therefore, subject to
foreign currency rate exposure. For non-U.S. subsidiaries and branches that have assets and liabilities in local currencies, the impact of the remeasurement of these local currencies into U.S. dollars for the six months ended June 27, 2008 was
immaterial. We have entered into forward foreign exchange contracts. As of June 27, 2008, we had five outstanding forward contracts with a total notional value of $23.8 million to purchase Malaysian Ringgits. These contracts are intended to
reduce our exposure to foreign currency rate changes related to the construction cost for our new building in Penang, Malaysia. The realized loss from the settlement of the forward contracts did not have a significant impact on our net income for
the three and six months ended June 27, 2008. We do not enter into foreign exchange transactions for trading or speculative purposes.

Common Stock

Off-Balance Sheet Arrangements

We do not have any financial partnerships with unconsolidated entities, such as entities often referred to as structured finance or special purpose
entities.

Subsequent Event

On
July 14, 2008, our board of directors declared a quarterly cash dividend of $0.05 per common share, which is payable on September 2, 2008 to shareholders of record on August 11, 2008.

Recent Accounting Pronouncements

In March 2008, the Financial Accounting Standards Board (FASB) issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133
(SFAS 161). This new standard requires enhanced disclosures for derivative instruments, including those used in hedging activities. SFAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008 and
will be applicable to the company in the first quarter of fiscal 2009. We are currently assessing the potential impact that the adoption of SFAS 161 may have on our condensed consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS 157). SFAS 157 defines fair value, establishes a
framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007,
and interim periods of those fiscal years. In February 2008, the FASB released a FASB Staff Position (FSP FAS 157-2Effective Date of FASB Statement No. 157) which delays, to fiscal years beginning after November 15, 2008, the
effective date of SFAS 157 for all non-financial assets and non-financial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). Effective December 29, 2007
we adopted SFAS 157, as it applies to our financial instruments. The adoption of SFAS 157 for financial assets and liabilities did not have a material impact on our condensed consolidated balance sheets, statements of income or cash flows. See Note
13  Fair Value of Financial Instruments.



|ITEM 3: | Quantitative and Qualitative Disclosures About Market Risk
|------- | ----------------------------------------------------------

Interest Rate Risk

Our exposure to market risk as a result of changes in interest rates relates primarily to our investment
portfolio and long-term credit facility. The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. We maintain investment portfolio holdings of various
issuers, types and maturity dates totaling $1.2 billion as of June 27, 2008. The market value of these investments on any given day during the investment term may vary as a result of market interest rate fluctuations. A hypothetical 10%
movement in interest rates during the investment term would not likely have a material impact on the fair value of the portfolio. The actual impact on the fair value of the portfolio in the future may differ materially from this analysis, depending
on actual balances and changes in the timing and the amount of interest rate movements.

Our consolidated operating results are dependent
on, among other factors, interest income and realized gains from the sale of marketable securities. If the interest rate declines or we are unable to realize gains from the sale of marketable securities, our consolidated operating results may be
negatively impacted.

In addition to our cash flows from operations, we derive our liquidity from our long-term credit facility (the
Facility). Our total borrowings under the Facility at June 27, 2008 were $500 million. Borrowings under this Facility bear a variable interest at either a Eurodollar rate (LIBOR) or a Prime rate, at our option, plus an
applicable margin based upon certain financial ratios, determined and payable quarterly. The interest rate as of June 27, 2008 was LIBOR plus 0.35%. In addition, we pay a facility fee on the entire Facility. This facility fee varies with
certain financial ratios and was 0.10% as of June 27, 2008.

Our consolidated operating results and cash flows are exposed to changes
in interest rates that could adversely affect the amount of interest expense incurred and paid on the Facility in any given period. Due to the variable interest rate on our Facility, the fair value of the Facility would not likely be materially
affected by any future changes in the interest rates.

Foreign Currency Risk

Although we purchase the majority of our materials and services in U.S. dollars and sell our products to OEMs and distributors in U.S. dollars, we do have
international operations and are, therefore, subject to foreign currency rate exposure. To date, our exposure to exchange rate volatility has been insignificant. As of June 27, 2008, we had five outstanding forward contracts with a total
notional value of $23.8 million to purchase Malaysian Ringgits. These contracts are intended to reduce our exposure to foreign currency rate changes related to the construction cost for our new building in Penang, Malaysia. If foreign currency rates
were to fluctuate by 10% from rates at June 27, 2008, our consolidated financial position, operating results and cash flows would not be materially affected. However, we cannot assure that there will not be a material impact in the future.

|ITEM 4: | Controls and Procedures
|------- | -----------------------

Evaluation of Disclosure Controls and
Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief
Financial Officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as amended, as of the end of the period
covered by this Quarterly Report on Form 10-Q (the Evaluation Date).

The purpose of this evaluation was to determine if, as of
the Evaluation Date, our disclosure controls and procedures were designed and operating effectively to provide reasonable assurance that the information relating to Altera, required to be disclosed in our Exchange Act filings (i) was recorded,
processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) was accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow
timely decisions regarding required disclosure.

Based on the evaluation, our Chief Executive Officer and Chief Financial Officer have
concluded that as of the Evaluation Date, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a  15(f) and 15(d)  15(f) under
the Exchange Act) that occurred during the period covered by this quarterly report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitation on Effectiveness of Controls

It should be
noted that any system of controls, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system are met. The design of any control system is based, in part, upon the benefits of the
control system relative to its costs. Control systems can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. In addition, over time, controls may become inadequate
because of changes in conditions, or the degree of compliance with the policies and procedures may deteriorate. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events.

PART II OTHER INFORMATION



|ITEM 1: | Legal Proceedings
|------- | -----------------

We have been named as a party to
several lawsuits concerning our historical stock option practices and related accounting and reporting.

In May and July 2006, we were
notified that three shareholder derivative lawsuits had been filed in the Superior Court of the State of California, County of Santa Clara, by persons identifying themselves as Altera shareholders and purporting to act on behalf of Altera, naming
Altera Corporation as a nominal defendant and naming some of our current and former officers and directors as defendants. On July 12, 2006, one of these derivative actions was voluntarily dismissed by the plaintiff shareholder. The remaining
two derivative lawsuits pending in Santa Clara Superior Court were consolidated into a single action on September 5, 2006. Plaintiffs filed a second amended consolidated complaint on December 15, 2006. On January 30, 2007, Altera and
the defendants filed a motion to stay this action pending resolution of the federal derivative action (discussed below). There have been no material developments in this action since January 30, 2007.

The consolidated California state court action names Altera Corporation as a nominal defendant and the following current and former Altera officers and
directors as defendants: John P. Daane, Nathan M. Sarkisian, Denis M. Berlan, Robert W. Reed, Robert J. Finocchio, Jr., Kevin McGarity, Paul Newhagen, William E. Terry, Susan Wang, Charles M. Clough, Rodney Smith, Michael B. Jacobs, Katherine E.
Schuelke, Deborah Reiman, Michael J. Ellison, C. Wendell Bergere, Clive McCarthy, and Peter Smyth. Plaintiffs assert claims against these individual defendants for breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate
assets, unjust enrichment, violations of California Corporation Code sections 25402 and 25403, breach of fiduciary duty for insider selling and misappropriation of information, rescission, constructive trust, accounting, and deceit. Plaintiffs
claims concern the granting of stock options by Altera between 1994 and 2001 and the alleged filing of false and misleading financial statements between 1994 and 2006. All of these claims are asserted derivatively on behalf of Altera. Plaintiffs
seek, among other relief, an indeterminate amount of damages from the individual defendants and a judgment directing Altera to reform its corporate governance practices.

##### Table of Contents

During the months of May, June, and July 2006, four other derivative lawsuits were filed by purported
Altera shareholders, on behalf of Altera, in the United States District Court for the Northern District of California. On August 8, 2006, these actions were consolidated, and the plaintiffs filed a consolidated complaint on November 30,
2006. During the third quarter of 2007, Altera moved to dismiss this action for lack of standing. The court granted Alteras motion in May 2008. The plaintiffs filed a first amended consolidated complaint on June 16, 2008, which Altera
moved to dismiss for lack of standing on July 15, 2008.

Among the defendants named in these derivative actions are Altera Corporation
as a nominal defendant and the following current and former officers and directors of Altera: John P. Daane, Nathan M. Sarkisian, Denis M. Berlan, Robert W. Reed, Robert J. Finocchio, Jr., Kevin McGarity, Paul Newhagen, William E. Terry, Susan Wang,
Charles M. Clough, Rodney Smith, Michael B. Jacobs, Katherine E. Schuelke, John R. Fitzhenry, Deborah Reiman, Michael J. Ellison, C. Wendell Bergere, Clive McCarthy, and Peter Smyth. The first amended consolidated complaint includes claims for
violations of Sections 10(b), 14(a), and 20(a) of the Securities Exchange Act of 1934, breach of fiduciary duty, corporate waste, gross mismanagement, unjust enrichment, abuse of control, insider selling and misappropriation of information,
rescission, accounting, and violations of California Corporation Code sections 25402 and 25502.5. Plaintiffs claims concern the granting of stock options by Altera between 1995 and 2001 and the alleged filing of false and misleading financial
statements between 1996 and 2005.



|ITEM 1A: | Risk Factors
|-------- | ------------

There have been no material changes
from the risk factors previously described under Item 1A of our Annual Report on Form 10-K for the year ended December 28, 2007. For additional information regarding risk factors, please refer to the description of the risk factors
associated with our business previously disclosed in Item 1A of our Annual Report on Form 10-K for the year ended December 28, 2007, which is incorporated herein by reference.

Before you decide to buy, hold, or sell our common stock, you should carefully consider the risks described in Item 1A of our Annual Report on Form
10K for the year ended December 28, 2007 and the other information contained elsewhere in this report. These risks are not the only risks facing our company. Additional risks and uncertainties not presently known to us or that we currently deem
immaterial may also affect our business. Our business, consolidated operating results and financial position could be seriously harmed if any of the events underlying any of these risks or uncertainties actually occurs. In that event, the market
price for our common stock could decline, and you may lose all or part of your investment.

We repurchase shares of our common stock under the program announced on July 15, 1996 that has no specified expiration. As of June 27, 2008, the board of directors has authorized, since the inception of the
program, a total of 183.0 million shares for repurchase. No existing repurchase plans or programs expired, nor have we decided to terminate any repurchase plans or programs prior to expiration. There are no existing plans or programs under
which we do not intend to make further purchases.
