Notes to Unaudited Condensed Consolidated Financial Statements

All numerical dollar and share references are in thousands, except for per share data.

(1) General—The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with United States (U.S.) generally accepted accounting principles (GAAP) and reflect all material normal recurring adjustments. However, certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the condensed consolidated financial statements include adjustments necessary for a fair presentation of the results of the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes included in our Annual Report on Form 10-K for the fiscal year ended January 31, 2011.

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingencies as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from these estimates. Any changes in estimates will be reflected in the financial statements in future periods.

(2) Summary of Significant Accounting Policies

Principles of Consolidation

The condensed consolidated financial statements include our financial statements and those of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

We do not have off-balance sheet arrangements, financings, or other similar relationships with unconsolidated entities or other persons, also known as special purpose entities. In the ordinary course of business, we lease certain equipment and certain real properties, primarily field sales offices, research and development facilities, and equipment, as described in Note 9. “Commitments and Contingencies.”

Revenue Recognition

We report revenue in two categories based on how the revenue is generated: (i) system and software and (ii) service and support.

System and software revenues – We derive system and software revenues from the sale of licenses of software products, emulation hardware systems, and finance fee revenues from our long-term installment receivables resulting from product sales. We primarily license our products using two different license types:

1. Term licenses – We use this license type primarily for software sales. This license type provides the customer with the right to use a fixed list of software products for a specified time period, typically three years, with payments spread over the license term, and does not provide the customer with the right to use the products after the end of the term. Term license arrangements may allow the customer to share products between multiple locations and remix product usage from the fixed list of products at regular intervals during the license term. We generally recognize product revenue from term license arrangements upon product delivery and start of the license term. In a term license agreement where we provide the customer with rights to unspecified or unreleased future products, we recognize revenue ratably over the license term.

2. Perpetual licenses – We use this license type for software and emulation hardware system sales. This license type provides the customer with the right to use the product in perpetuity and typically does not provide for extended payment terms. We generally recognize product revenue from perpetual license arrangements upon product delivery assuming all other criteria for revenue recognition have been met.

We include finance fee revenues from the accretion on the discount of long-term installment receivables in system and software revenues.

Service and support revenues – We derive service and support revenues from software and hardware post-contract maintenance or support services and professional services, which include consulting, training, and other services. We recognize revenue ratably over the support services term. We record professional service revenue as the services are provided to the customer.

6

We determine whether product revenue recognition is appropriate based upon the evaluation of whether the following four criteria have been met:

1. Persuasive evidence of an arrangement exists – Generally, we use either a customer signed contract or qualified customer purchase order as evidence of an arrangement for both term and perpetual licenses. For professional service engagements, we generally use a signed professional services agreement and a statement of work to evidence an arrangement. Sales through our distributors are evidenced by an agreement governing the relationship, together with binding purchase orders from the distributor on a transaction-by-transaction basis.

2. Delivery has occurred – We generally deliver software and the corresponding access keys to customers electronically. Electronic delivery occurs when we provide the customer access to the software. We may also deliver the software on a compact disc. With respect to emulation hardware systems, we transfer title to the customer upon shipment. Our software license and emulation hardware system agreements generally do not contain conditions for acceptance.

3. Fee is fixed or determinable – We assess whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. We have established a history of collecting under the original contract with installment terms without providing concessions on payments, products, or services. Additionally, for installment contracts, we determine that the fee is fixed or determinable if the arrangement has a payment schedule that is within the term of the licenses and the payments are collected in equal or nearly equal installments, when evaluated on a cumulative basis. If the fee is not deemed to be fixed or determinable, we recognize revenue as payments become due and payable.

Significant judgment is involved in assessing whether a fee is fixed or determinable. We must also make these judgments when assessing whether a contract amendment to a term arrangement (primarily in the context of a license extension or renewal) constitutes a concession. Our experience has been that we are able to determine whether a fee is fixed or determinable for term licenses. If we no longer were to have a history of collecting under the original contract without providing concessions on term licenses, revenue from term licenses would be required to be recognized when payments under the installment contract become due and payable. Such a change could have a material impact on our results of operations.

4. Collectibility is probable – To recognize revenue, we must judge collectibility of the arrangement fees on a customer-by-customer basis pursuant to our credit review process. We typically sell to customers with whom there is a history of successful collection. We evaluate the financial position and a customer’s ability to pay whenever an existing customer purchases new products, renews an existing arrangement, or requests an increase in credit terms. For certain industries for which our products are not considered core to the industry or the industry is generally considered troubled, we impose higher credit standards. If we determine that collectibility is not probable based upon our credit review process or the customer’s payment history, we recognize revenue as payments are received.

Multiple element arrangements involving software licenses – For multiple element arrangements involving software and other software-related deliverables, vendor-specific objective evidence of fair value (VSOE) must exist to allocate the total fee among all delivered and non-essential undelivered elements of the arrangement. If undelivered elements of the arrangement are essential to the functionality of the product, we defer revenue until the essential elements are delivered. If VSOE does not exist for one or more non-essential undelivered elements, we defer revenue until such evidence exists for the undelivered elements, or until all elements are delivered, whichever is earlier. If VSOE of all non-essential undelivered elements exist but VSOE does not exist for one or more delivered elements, we recognize revenue using the residual method. Under the residual method, we defer revenue related to the undelivered elements based upon VSOE and we recognize the remaining portion of the arrangement fee as revenue for the delivered elements, assuming all other criteria for revenue recognition are met. If we can no longer establish VSOE for non-essential undelivered elements of multiple element arrangements, we defer revenue until all elements are delivered or VSOE was established for the undelivered elements, whichever is earlier.

We base our VSOE for certain product elements of an arrangement upon the pricing in comparable transactions when the element is sold separately. We primarily base our VSOE for term and perpetual support services upon customer renewal history where the services are sold separately. We also base VSOE for professional services and installation services for emulation hardware systems upon the price charged when the services are sold separately.

Multiple element arrangements involving hardware – For multiple element arrangements involving our emulation hardware systems, we allocate revenue to each element based on the relative selling price of each deliverable. In order to meet the separation criteria to allocate revenue to each element we must determine the standalone selling price of each element using a hierarchy of evidence. The authoritative guidance requires that, in the absence of VSOE or third-party evidence (TPE), a company must develop an estimated selling price (ESP). ESP is defined as the price at which the vendor would transact if the deliverable was sold by the vendor regularly on a standalone basis. A company should consider market conditions as well as entity-specific factors when estimating a selling price.

When VSOE or TPE does not exist, we base our ESP for certain elements in arrangements based on either costs incurred to manufacture a product plus a reasonable profit margin or standalone sales to similar customers. In

7

determining profit margins, we consider current market conditions, pricing strategies related to the class of customer, and the level of penetration we have with the customer. In other cases, we may have limited sales on a standalone basis to the same or similar customers and/or guaranteed pricing on future purchases of the same item. If we are unable to demonstrate value on a standalone basis of an element, we could be required to combine elements which could impact the timing of revenue recognition if not delivered together.

Reclassification

Certain immaterial reclassifications have been made in the condensed consolidated balance sheet to correct the presentation as of January 31, 2011. Specifically, we made a reclassification to other assets of $5,481 which was incorrectly classified as other receivables.

(3) Fair Value Measurement—We measure financial instruments at fair value on a quarterly basis. The Financial Accounting Standards Board established a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources. Unobservable inputs reflect our market assumptions. The fair value hierarchy consists of the following three levels:

• Level 1—Quoted prices for identical instruments in active markets;

• Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations whose significant inputs are observable; and

• Level 3—One or more significant inputs to the valuation model are unobservable.

The following table presents information about financial assets and liabilities required to be carried at fair value on a recurring basis as of April 30, 2011:

	Fair Value			Level 1		Level 2		Level 3
Foreign currency exchange contracts	$	1,851		$	—	$	1,851	$	—
Contingent consideration		(6,475	)		—		—		(6,475	)
Total	$	(4,624	)	$	—	$	1,851	$	(6,475	)

The following table presents information about financial assets and liabilities required to be carried at fair value on a recurring basis as of January 31, 2011:

	Fair Value			Level 1		Level 2		Level 3
Foreign currency exchange contracts	$	826		$	—	$	826	$	—
Contingent consideration		(5,342	)		—		—		(5,342	)
Total	$	(4,516	)	$	—	$	826	$	(5,342	)

In connection with certain acquisitions, payment of a portion of the purchase price is contingent upon the acquired business’ achievement of certain revenue goals. We have estimated the fair value of this contingent consideration as the present value of the expected contingent payments over the term of the arrangements and have included $795 of the balance in accrued liabilities and the remaining $5,680 in other long-term liabilities on our condensed consolidated balance sheet.

The following table summarizes Level 3 activity:

Balance as of January 31, 2011	$	5,342
Additions		1,090
Payments		(8	)
Interest accretion		51
Balance as of April 30, 2011	$	6,475

8

The following table summarizes the fair value and carrying value of notes payable:

As of	April 30, 2011		January 31, 2011
Fair value of notes payable	$	263,484	$	222,591
Carrying value of notes payable	$	210,787	$	209,348

We based the fair value of notes payable on the quoted market price or rates available to us for instruments with similar terms and maturities. Of the total carrying value of notes payable, $2,000 as of January 31, 2011 was classified as current on our condensed consolidated balance sheets. The carrying amount of short-term borrowings of $9,055 as of April 30, 2011 and $15,544 as of January 31, 2011 approximates fair value because of the short-term nature of the instruments.

(4) Business Combinations—For each business we acquire, the excess of the fair value of the consideration transferred over the fair value of the net tangible assets acquired and net tangible liabilities assumed was allocated to various identifiable intangible assets and goodwill. Identifiable intangible assets typically consist of purchased technology and customer-related intangibles, which are amortized to expense over their useful lives. Goodwill, representing the excess of the purchase consideration over the fair value of net tangible and identifiable intangible assets, is not amortized.

During the three months ended April 30, 2011, we acquired one privately-held company, which was not material individually or in the aggregate, for a total consideration of $1,890.

The separate results of operations for the acquisitions during the three months ended April 30, 2011 were not material, individually or in the aggregate, compared to our overall results of operations and accordingly, pro-forma financial statements of the combined entities have been omitted.

(5) Derivative Instruments and Hedging Activities—We are exposed to fluctuations in foreign currency exchange rates. To manage the volatility, we aggregate exposures on a consolidated basis to take advantage of natural offsets. The primary exposures are the Japanese yen, where we are in a long position, and the euro and the British pound, where we are in a short position. Most large European revenue contracts are denominated and paid to us in U.S. dollars while our European expenses, including substantial research and development operations, are paid in local currencies causing a short position in the euro and the British pound. In addition, we experience greater inflows than outflows of Japanese yen as almost all Japanese-based customers contract and pay us in Japanese yen. While these exposures are aggregated on a consolidated basis to take advantage of natural offsets, substantial exposures remain.

To partially offset the net exposures in the euro, British pound, and the Japanese yen, we enter into foreign currency exchange contracts of less than one year which are designated as cash flow hedges. Any gain or loss on Japanese yen contracts is classified as product revenue when the hedged transaction occurs while any gain or loss on euro and British pound contracts is classified as operating expense when the hedged transaction occurs.

We formally document all relationships between foreign currency exchange contracts and hedged items as well as our risk management objectives and strategies for undertaking various hedge transactions. All hedges designated as cash flow hedges are linked to forecasted transactions and we assess, both at inception of the hedge and on an ongoing basis, the effectiveness of the foreign currency exchange contracts in offsetting changes in the cash flows of the hedged items. We report the effective portions of the net gains or losses on foreign currency exchange contracts as a component of accumulated other comprehensive income in stockholders’ equity. Accumulated other comprehensive income associated with hedges of forecasted transactions is reclassified to the condensed consolidated statement of operations in the same period the forecasted transaction occurs. We discontinue hedge accounting prospectively when we determine that a foreign currency exchange contract is not highly effective as a hedge. To the extent a forecasted transaction is no longer deemed probable of occurring, we prospectively discontinue hedge accounting treatment and we reclassify deferred amounts to other expense, net in the condensed consolidated statement of operations. We noted no such instance during the three months ended April 30, 2011 or 2010.

The fair values and balance sheet presentation of our derivative instruments as of April 30, 2011 are summarized as follows:

	Location		Asset Derivatives		Liability Derivatives
Derivatives designated as hedging instruments:
Cash flow forwards		Other receivables	$	725	$	(161	)
Derivatives not designated as hedging instruments:
Non-designated forwards		Other receivables		1,911		(624	)
Total derivatives			$	2,636	$	(785	)

The fair values and balance sheet presentation of our derivative instruments as of January 31, 2011 are summarized as follows:

	Location		Asset Derivatives		Liability Derivatives
Derivatives designated as hedging instruments:
Cash flow forwards		Other receivables	$	575	$	(414	)
Derivatives not designated as hedging instruments:
Non-designated forwards		Other receivables		1,125		(460	)
Total derivatives			$	1,700	$	(874	)

During the three months ended April 30, 2011, we entered into 366 new foreign currency forward contracts. We had a total of 37 contracts outstanding with a total gross notional value of $126,716 outstanding as of April 30, 2011. For the three months ended April 30, 2010, we entered into 337 new foreign currency contracts. We had a total of 43 contracts with a total gross notional value of $203,281 outstanding as of April 30, 2010. Notional amounts do not quantify risk or represent our assets or liabilities but are used in the calculation of cash settlements under the contracts.

By using derivative instruments, we subject ourselves to credit risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair value of the derivative instrument. Generally, when the fair value of our derivative contracts is a net asset, the counterparty owes us, thus creating a receivable risk. We minimize counterparty credit risk by entering into derivative transactions with major financial institutions and, therefore, we do not expect material losses as a result of default by our counterparties.

The pre-tax effect of derivative instruments in cash flow hedging relationships on income and other comprehensive income (OCI) for the three months ended April 30, 2011 is as follows:

Derivatives Designated as Hedging Instruments	Gain Recognized in OCI on Derivatives (Effective Portion)		Gain (loss) Reclassified from Accumulated OCI into Income (Effective  Portion)				Gain Recognized in Income on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing)
	Amount		Location	Amount			Location	Amount
Cash flow forwards	$	586	Revenues	$	(449	)	Other expense, net	$	24
			Operating expenses		560
Total	$	586		$	111			$	24

The gain on cash flow forwards of $24 recognized in other expense, net for the three months ended April 30, 2011 is related to the time value exclusion of foreign currency forward contracts from our assessment of hedge effectiveness.

The pre-tax effect of derivative instruments in cash flow hedging relationships on income and OCI for the three months ended April 30, 2010 is as follows:

Derivatives Designated as Hedging Instruments	Loss Recognized in OCI on Derivatives (Effective Portion)			Loss Reclassified from Accumulated OCI into Income (Effective Portion)				Gain Recognized in Income on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing)
	Amount			Location	Amount			Location	Amount
Cash flow forwards	$	(1,250	)	Revenues	$	(131	)	Other expense, net	$	30
				Operating expenses		(1,713	)
Total	$	(1,250	)		$	(1,844	)		$	30

The gain on cash flow forwards of $30 recognized in other expense, net for the three months ended April 30, 2010 was related to the time value exclusion of foreign currency forward contracts from our assessment of hedge effectiveness.

The hedge balance in accumulated other comprehensive income was as follows:

As of	April 30, 2011		January 31, 2011
Accumulated OCI before tax effect	$	545	$	69
Accumulated OCI after tax effect	$	455	$	(2	)

The balance represents a net unrealized gain on foreign currency exchange contracts related to hedges of forecasted revenues and expenses expected to occur within the next twelve months. We will transfer this amount to the condensed consolidated statement of operations upon recognition of the related revenues and recording of the respective expenses. We expect substantially all of the hedge balance in accumulated other comprehensive income to be reclassified to the condensed consolidated statement of operations within the next twelve months.

We enter into foreign currency exchange contracts to offset the earnings impact relating to the variability in exchange rates on certain short-term monetary assets and liabilities denominated in non-functional currencies. We do not designate these foreign currency contracts as hedges. The effect of derivative instruments not designated as hedging instruments on income is as follows:

Derivatives Not Designated as Hedging Instruments	Gain Recognized in Income on Derivatives
	Location	Amount as of April 30, 2011		Amount as of April 30, 2010
Non-designated forwards	Other expense, net	$	3,281	$	1,423

(6) Term Receivables and Trade Accounts Receivable—We have long-term installment receivables that are attributable to multi-year, multi-element term license sales agreements. We include balances under term agreements that are due within one year in trade accounts receivable, net and balances that are due more than one year from the balance sheet date in term receivables, long-term. We discount the total product portion of the agreements to reflect the interest component of the transaction. We amortize the interest component of the transaction, using the effective interest method, to system and software revenues over the period in which payments are made and balances are outstanding. We determine the discount rate at the outset of the arrangement based upon the current credit rating of the customer. We reset the discount rate periodically considering changes in prevailing interest rates but do not adjust previously discounted balances.

11

Term receivable and trade accounts receivable balances were as follows:

As of	April 30, 2011		January 31, 2011
Trade accounts receivable	$	139,028	$	153,733
Term receivables, short-term	$	182,012	$	193,342
Term receivables, long-term	$	179,014	$	167,425

Trade accounts receivable include billed amounts whereas term receivables, short-term is comprised of unbilled amounts. Term receivables, short term represent the portion of long-term installment agreements that are due within one year. Billings for term agreements typically occur 30 days prior to the contractual due date, in accordance with individual contract installment terms. Term receivables, long-term represent unbilled amounts which are scheduled to be collected beyond one year.

We perform a credit risk assessment of all customers using the S&P credit rating as our primary credit-quality indicator. The S&P credit ratings are based on the most recent S&P score available. For customers that do not have an S&P credit rating, we base our credit risk assessment on an internal credit assessment which is based on selected short-term financial ratios. Our internal credit assessment is based upon results provided in the customers’ most recent financial statements.

The credit risk assessment for our long-term receivables was as follows:

As of	April 30, 2011		January 31, 2011
S&P credit rating:
AAA+ through BBB-	$	106,906	$	84,685
BB+ and lower		11,594		19,473
		118,500		104,158
Internal credit assessment		60,514		63,267
Total long-term term receivables	$	179,014	$	167,425

We maintain allowances for doubtful accounts on trade accounts receivable and term receivables, long-term for estimated losses resulting from the inability of our customers to make required payments. We regularly evaluate the collectibility of our trade accounts receivable based on a combination of factors. When we become aware of a specific customer’s inability to meet its financial obligations, such as in the case of bankruptcy or deterioration in the customer’s operating results, financial position, or credit rating, we record a specific reserve for bad debt to reduce the related receivable to the amount believed to be collectible. We also record unspecified reserves for bad debt for all other customers based on a variety of factors including length of time the receivables are past due, the financial health of the customers, the current business environment, and historical experience. Current economic conditions we have considered include forecasted spending in the semiconductor industry, consumer spending for electronics, integrated circuit research and development spending, and volatility in gross domestic product. If these factors change or circumstances related to specific customers change, we adjust the estimates of the recoverability of receivables resulting in either additional selling expense or a reduction in selling expense in the period such determination is made.

The following shows the change in allowance for doubtful accounts for the three months ended April 30, 2011:

	Beginning balance as of January 31, 2011		Charged (credited) to expense			Deductions(1)		Ending balance as of April 30, 2011
Allowance for doubtful accounts	$	3,941	$	(182	)	$	21	$	3,780

⁽¹⁾  Specific account write-offs and foreign exchange.

We enter into agreements to sell qualifying accounts receivable from time to time to certain financing institutions on a non-recourse basis. We received net proceeds from the sale of receivables of $11,403 for the three months ended April 30, 2011 compared to $14,909 for the three months ended April 30, 2010.

(7) Short-Term Borrowings—Short-term borrowings consisted of the following:

As of	April 30, 2011		January 31, 2011
Collections of previously sold accounts receivable	$	4,143	$	10,680
Other borrowings		4,912		4,864
Short-term borrowings	$	9,055	$	15,544

In April 2011, we entered into a syndicated, senior, unsecured, four-year revolving credit facility that terminates April 27, 2015. The revolving credit facility has a maximum borrowing capacity of $125,000. Under this revolving credit facility, we have the option to pay interest based on:

(i) London Interbank Offered Rate (LIBOR) with varying maturities commensurate with the borrowing period we select, plus a spread of between 2.25% and 3.25% based on a pricing grid tied to a financial covenant, or

(ii) A base rate plus a spread of between 1.25% and 2.25%, based on a pricing grid tied to a financial covenant.

The base rate is defined as the highest of:

(i) The federal funds rate, as defined, plus 0.5%,

(ii) The prime rate of the lead bank, or

(iii) One-month LIBOR plus 1.0%.

As a result of these interest rate options, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. In addition, commitment fees are payable on the unused portion of the revolving credit facility at rates between 0.40% and 0.50% based on a pricing grid tied to a financial covenant. We paid commitment fees as follows:

Three months ended April 30,	2011		2010
Commitment fees	$	80	$	66

This revolving credit facility contains certain financial and other covenants, including the following:

• Our adjusted quick ratio (ratio of the sum of cash and cash equivalents, short-term investments, and net current receivables to total current liabilities) shall not be less than 1.00;

• Our tangible net worth (stockholders’ equity less goodwill and other intangible assets) must exceed the calculated required tangible net worth as defined in the credit agreement, which establishes a fixed level of required tangible net worth. Each quarter the required level increases by 70% of any positive net income in the quarter (but in the aggregate no more than 70% of positive net income for any full fiscal year), 100% of the amortization of intangible assets in the quarter, and 100% of certain stock issuance proceeds. The required level also decreases each quarter by 50% of amounts paid for dividends or repurchases of our stock and certain amounts of acquired intangible assets;

• Our leverage ratio (ratio of total liabilities less subordinated debt to the sum of subordinated debt and tangible net worth) shall be less than 2.00;

• Our senior leverage ratio (ratio of total debt less subordinated debt to the sum of subordinated debt and tangible net worth) shall not be greater than 0.90; and

• Our minimum cash and accounts receivable ratio (ratio of the sum of cash and cash equivalents, short-term investments, and 42.0% of net current accounts receivable, to outstanding credit agreement borrowings) shall not be less than 1.25.

The revolving credit facility limits the aggregate amount we can pay for dividends and repurchases of our stock over the four year term of the facility to $50,000 plus 70% of our cumulative net income.

We were in compliance with all financial covenants as of April 30, 2011. If we were to fail to comply with the financial covenants and do not obtain a waiver from our lenders, we would be in default under the revolving credit facility and our lenders could terminate the facility and demand immediate repayment of all outstanding loans under the revolving credit facility.

Short-term borrowings include amounts collected from customers on accounts receivable previously sold on a non-recourse basis to financial institutions. These amounts are remitted to the financial institutions in the following quarter.

We generally have other short-term borrowings, including multi-currency lines of credit, capital leases, and other borrowings. Interest rates are generally based on the applicable country’s prime lending rate, depending on the currency borrowed.

(8) Notes Payable—Notes payable consist of the following:

As of	April 30, 2011		January 31, 2011
4.00% Debentures due 2031	$	209,474	$	—
6.25% Debentures due 2026, issued 2006		—		157,843
6.25% Debentures due 2026, issued fiscal 2011		—		31,705
Term Loan due 2013		—		18,500
Other		1,313		1,300
Notes payable		210,787		209,348
Term Loan due 2013, current portion		—		(2,000	)
Notes payable, long-term	$	210,787	$	207,348

4.00% Debentures due 2031: In April 2011, we issued $253,000 of 4.00% Convertible Subordinated Debentures (4.00% Debentures) due 2031 in a private placement pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the 4.00% Debentures is payable semi-annually in April and October.

The 4.00% Debentures are convertible, under certain circumstances, into our common stock at a conversion price of $20.538 per share for a total of 12,319 shares as of April 30, 2011. These circumstances include:

• The market price of our common stock exceeding 120% of the conversion price;

• A call for redemption of the 4.00% Debentures;

• Specified distributions to holders of our common stock;

• If a fundamental change, such as a change of control, occurs;

• During the two months prior to, but not on, the maturity date; or

• The market price of the 4.00% Debentures declining to less than 98% of the value of the common stock into which the 4.00% Debentures are convertible.

Upon conversion of any 4.00% Debentures, a holder will receive:

(i) Cash up to the principal amount of the 4.00% Debentures that are converted; and

(ii) Cash or shares of common stock, at our election, for the excess, if any, of the value of the converted shares over the principal amount.

If a holder elects to convert their 4.00% Debentures in connection with a fundamental change in the company that occurs prior to April 5, 2016, the holder will also be entitled to receive a make whole premium upon conversion in some circumstances.

We may redeem some or all of the 4.00% Debentures for cash on or after April 5, 2016 at the following redemption prices expressed as a percentage of principal, plus any accrued and unpaid interest:

Period	Redemption Price
Beginning on April 5, 2016 and ending on March 31, 2017		101.143	%
Beginning on April 1, 2017 and ending on March 31, 2018		100.571	%
On April 1, 2018 and thereafter		100.000	%

The holders, at their option, may redeem the 4.00% Debentures in whole or in part for cash on April 1, 2018, April 1, 2021, and April 1, 2026, and in the event of a fundamental change in the company. In each case, our repurchase price will be 100% of the principal amount of the 4.00% Debentures plus any accrued and unpaid interest.

14

As the 4.00% Debentures contain conversion features that the debt may be settled in cash upon conversion, we separately account for the implied liability and equity components of the 4.00% Debentures. The principal amount, unamortized debt discount, net carrying amount of the liability component, and carrying amount of the equity component of the 4.00% Debentures are as follows:

As of	April 30, 2011
Principal amount	$	253,000
Unamortized debt discount		(43,526	)
Net carrying amount of the liability component	$	209,474
Equity component	$	43,930

The unamortized debt discount will be amortized to interest expense using the effective interest method through March 2018.

We recognized the following amounts in interest expense in the condensed consolidated statement of operations related to the 4.00% debentures:

Three months ended April 30,	2011
Interest expense at the contractual interest rate	$	759
Amortization of debt discount	$	404

The effective interest rate on the 4.00% Debentures was 7.25% for the three months ended April 30, 2011.

6.25% Debentures due 2026: In March 2006, we issued $200,000 of 6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026 in a private offering pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the 6.25% Debentures was payable semi-annually in March and September.

The principal amount, unamortized debt discount, net carrying amount of the liability component, and carrying amount of the equity component of the 6.25% Debentures, issued 2006, were as follows:

As of	April 30, 2011		January 31, 2011
Principal amount	$	—	$	165,000
Unamortized debt discount		—		(7,157	)
Net carrying amount of the liability component	$	—	$	157,843
Equity component	$	—	$	21,766

We recognized the following amounts in interest expense in the condensed consolidated statements of operations related to the 6.25% Debentures, issued 2006:

Three months ended April 30,	2011		2010
Interest expense at the contractual interest rate	$	2,900	$	2,578
Amortization of debt discount	$	793	$	729

The effective interest rate on the 6.25% Debentures, was 8.60% for the three months ended April 30, 2011 and 2010.

The principal amount, unamortized premium, and net carrying amount of the 6.25% Debentures, issued fiscal 2011, were as follows:

As of	April 11, 2011		January 31, 2011
Principal amount	$	—	$	31,509
Unamortized debt premium		—		196
Net carrying amount of the liability component	$	—	$	31,705

No equity component was recorded for the 6.25% Debentures, issued fiscal 2011, as the conversion feature was deemed to be non-beneficial when the debt was issued.

During the three months ended April 30, 2011, we redeemed the remaining $196,509 principal amount of 6.25% Debentures utilizing proceeds received from the issuance of the 4.00% Debentures and cash on hand. In connection with this redemption, we incurred a before tax net loss on the early extinguishment of debt of $11,192, which included a $6,190 write-off of net unamortized debt discount, a $3,518 premium on redemption of the 6.25% Debentures, and a write-off of $1,484 for the unamortized debt issuance costs. This loss is included in interest expense on the condensed consolidated statement of operations. No balance remains outstanding following this redemption.

15

Term Loan due 2013: In April 2010, we entered into a three-year term loan (Term Loan) for $20,000 to repay borrowings under our revolving credit facility used to purchase office buildings in Fremont, California. Fixed principal of $500 and accrued interest payments were payable quarterly in February, May, August, and November.

During the three months ended April 30, 2011, we repaid the remaining obligation of $18,500 under the Term Loan utilizing proceeds received from the issuance of the 4.00% Debentures. In connection with this repayment, we incurred a before tax net loss on early retirement of debt of $312, representing the write-off of the unamortized debt issuance costs. This loss is included in interest expense on the condensed consolidated statement of operations. The effective interest rate was 4.81% for the three months ended April 30, 2011. No balance remains outstanding following this repayment.

Other Notes Payable: In November 2009, we issued a subordinated note payable as part of a business combination. The note bears interest at a rate of 3.875% and is due in full along with all accrued interest on November 17, 2012.

(9) Commitments and Contingencies

Leases

We lease a majority of our field sales offices and research and development facilities under non-cancelable operating leases. In addition, we lease certain equipment used in our research and development activities. This equipment is generally leased on a month-to-month basis after meeting a six-month lease minimum. There have been no significant changes to the future minimum lease payments due under non-cancelable operating leases disclosed in our Annual Report on Form 10-K for the fiscal year ended January 31, 2011.

Indemnifications

Our license and services agreements generally include a limited indemnification provision for claims from third parties relating to our intellectual property. The indemnification is generally limited to the amount paid by the customer or a set cap. As of April 30, 2011, we were not aware of any material liabilities arising from these indemnification obligations.

Legal Proceedings

From time to time we are involved in various disputes and litigation matters that arise in the ordinary course of business. These include disputes and lawsuits relating to intellectual property rights, contracts, distributorships, and employee relations matters. Periodically, we review the status of various disputes and litigation matters and assess our potential exposure. When we consider the potential loss from any dispute or legal matter probable and the amount or the range of loss can be estimated, we will accrue a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, we base accruals on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation matters and may revise estimates. We believe that the outcome of current litigation, individually and in the aggregate, will not have a material effect on our results of operations.

(10) Employee Stock and Savings Plans

Stock Options Plans and Stock Plans

On July 1, 2010, our shareholders approved the 2010 Omnibus Incentive Plan (Incentive Plan) which replaced our prior 1982 Stock Option Plan, Nonqualified Stock Option Plan, 1986 Stock Plan, and 1987 Non-Employee Directors’ Stock Plan. The Incentive Plan is administered by the Compensation Committee of our Board of Directors and permits accelerated vesting of outstanding options, restricted stock units, restricted stock awards, and other equity incentives upon the occurrence of certain changes in control of our company. The implementation of the Incentive Plan did not modify the terms of any awards granted under prior plans.

Stock options under the Incentive Plan are generally expected to vest over four years, have an expiration date of ten years from the date of grant, and an exercise price not less than the fair market value of the shares on the date of grant.

As of April 30, 2011, a total of 8,924 shares of common stock were available for future grant under the above Incentive Plan.

We assumed the stock plans of Valor Computerized Systems, Ltd. (Valor) on March 18, 2010. Under the terms of our merger agreement with Valor, options outstanding under these plans were converted to options to purchase shares of our common stock. Options issued under these plans vest over four years from the original grant date and have an expiration date of ten years from the original grant date. The exercise price of each converted option is equal to the product of the original exercise price and the original number of options granted divided by the number of converted options received. These stock plans have been suspended and no future awards will be granted under these plans. Options for a total of 2,160 shares of our common stock have been authorized and issued under the Valor plans.

16

On December 14, 2009, our shareholders approved the exchange of certain options for restricted stock units. Eligible for the exchange were options held by non-executive employees with an exercise price equal to or greater than $11.00 which were granted prior to January 7, 2009 and expire after August 15, 2010. The offer expired February 5, 2010. Effective February 8, 2010 a total of 6,945 options were exchanged for 557 restricted stock units. Total incremental cost of $491 resulted from this exchange. The incremental cost will be amortized over two years.

Stock options outstanding, the weighted average exercise price, and transactions involving the stock option plans are summarized as follows:

	Options Outstanding			Weighted Average Exercise Price
Balance as of January 31, 2011		11,867		$	9.94
Granted		—			—
Exercised		(1,096	)		6.76
Forfeited		(73	)		8.11
Expired		(23	)		17.13
Balance as of April 30, 2011		10,675		$	10.27

The following table summarizes activity involving restricted stock, including restricted stock units:

	Restricted Stock			Weighted Average Grant Date Fair Value
Nonvested as of January 31, 2011		2,131		$	9.61
Granted		107			15.29
Released		(229	)		8.07
Cancelled		(26	)		9.74
Nonvested as of April 30, 2011		1,983		$	10.22

Employee Stock Purchase Plans

We have an employee stock purchase plan (ESPP) for U.S. employees and an ESPP for certain foreign subsidiary employees. The ESPPs provide for six month offerings commencing on January 1 and July 1 of each year with purchases on June 30 and December 31 of each year. Each eligible employee may purchase up to six thousand shares of stock on each purchase date at prices no less than 85% of the lesser of the fair market value of the shares on the offering date or on the purchase date. As of April 30, 2011, 3,934 shares remain available for future purchase under the ESPPs.

Stock-Based Compensation Expense

We estimate the fair value of stock options and purchase rights under our ESPPs using a Black-Scholes option-pricing model. The Black-Scholes option-pricing model incorporates several highly subjective assumptions including expected volatility, expected term, and interest rates.

In reaching our determination of expected volatility for options, we include the following elements:

• Historical volatility of our shares of common stock;

• Historical volatility of shares of comparable companies;

• Implied volatility of our traded options; and

• Implied volatility of traded options of comparable companies.

In determining expected volatility for purchase rights under our ESPP, we use the historical volatility of our shares of common stock. The expected term is the six month offering period. We base the expected term of our stock options on historical experience.

The risk-free interest rate for periods within the contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of the grant.

17

The fair value of restricted stock units is the market value as of the grant date.

The weighted average grant date fair values are summarized as follows:

Three months ended April 30,	2011		2010
Options granted	$	—	$	4.29
Restricted stock units granted	$	15.29	$	7.99
ESPP purchase rights	$	—	$	—

The fair value calculations used the following assumptions:

Three months ended April 30,	2010
Stock Option Plans
Risk-free interest rate		2.4	%
Dividend yield		0	%
Expected life (in years)		5.5
Weighted average volatility		55	%
Three months ended April 30,	2010
Acquired Company Options Exchange
Risk-free interest rate		0.1% - 3.3	%
Dividend yield		0	%
Expected life (in years)		0.1 - 7.7
Volatility (range)		35% - 72	%
Weighted average volatility		60	%
Three months ended April 30,	2010
Employee Options Exchange
Risk-free interest rate		0.2% - 2.7	%
Dividend yield		0	%
Expected life (in years)		0.5 - 5.9
Volatility (range)		43% - 77	%
Weighted average volatility		43	%

(11) Incentive Stock Rights—Our Board of Directors has the authority to issue incentive stock in one or more series and to determine the relative rights and preferences of the incentive stock. On June 24, 2010, we adopted an Incentive Stock Purchase Rights Plan and declared a dividend distribution of one Right for each outstanding share of common stock, payable to holders of record on July 6, 2010. As long as the Rights are attached to our common stock, we will issue one Right with each new share of common stock so that all such shares will have attached Rights. Under certain conditions, each Right may be exercised to purchase 1/10,000 of a share of Series B Junior Participating Incentive Stock (Incentive Stock) at a purchase price of fifty dollars, subject to adjustment. The Rights are not presently exercisable and will only become exercisable if a person or group acquires or commences a tender offer to acquire 15% or more of our common stock. If a person or group acquires 15% or more of the common stock, each Right will be adjusted to entitle its holder to receive, upon exercise, common stock (or, in certain circumstances, other assets of ours) having a value equal to two times the exercise price of the Right or each Right will be adjusted to entitle its holder to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the Right, depending on the circumstances. The Rights expire on December 31, 2011 and may be redeemed by us for $0.001 per Right. The Rights do not have voting or dividend rights and have no dilutive effect on our earnings.

(12) Net Loss Per Share—We compute basic net loss per share using the weighted average number of common shares outstanding during the period. We compute diluted net loss per share using the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of common shares issuable upon exercise of stock options, restricted stock units, purchase rights from ESPPs, and warrants using the treasury stock method and common shares issuable upon conversion of the convertible subordinated debentures, if dilutive.

18

The following provides the computation of basic and diluted net loss per share:

	Three months ended April 30,
	2011			2010
Net loss	$	(2,353	)	$	(23,025	)
Weighted average common shares used to calculate basic and diluted net loss per share		111,769			103,763
Basic and diluted net loss per share	$	(0.02	)	$	(0.22	)

We excluded from the computation of diluted net loss per share stock options, restricted stock units, and ESPP purchase rights to purchase 6,959 shares of common stock for the three months ended April 30, 2011 compared to 16,938 for the three months ended April 30, 2010. The stock options, restricted stock units, and ESPP purchase rights were anti-dilutive either because we incurred a net loss for the period or the stock options were determined to be anti-dilutive as a result of applying the treasury stock method.

The effect of the conversion of the Floating Rate Convertible Subordinated Debentures (Floating Rate Debentures) due 2023 (retired during fiscal 2011), the 6.25% Debentures (retired during the three months ended April 30, 2011), and the 4.00% Debentures was anti-dilutive and therefore excluded from the computation of diluted net income (loss) per share. We assume that the 6.25% Debentures and the 4.00% Debentures will be settled in common stock for purposes of calculating the dilutive effect of the 6.25% Debentures and the 4.00% Debentures.

The conversion features of the 4.00% Debentures, which allow for settlement in cash or a combination of cash and common stock, are further described in Note 8. “Notes Payable.”

(13) Comprehensive Income (Loss)—The following provides a summary of comprehensive income (loss):

Three months ended April 30,	2011			2010
Net loss	$	(2,353	)	$	(23,025	)
Change in unrealized gain on derivative instruments		457			611
Change in accumulated translation adjustment		9,084			(3,764	)
Comprehensive income (loss)	$	7,188		$	(26,178	)

(14) Special Charges—The following is a summary of the components of the special charges:

Three months ended April 30,	2011		2010
Employee severance and related costs	$	1,147	$	1,589
Excess leased facility costs		252		474
Other costs		3,148		1,205
Total special charges	$	4,547	$	3,268

Special charges primarily consist of costs incurred for employee terminations due to a reduction of personnel resources driven by modifications of business strategy or business emphasis. Special charges may also include expenses incurred related to acquisitions, excess facility costs, and asset related charges.

Employee severance and related costs of $1,147 for the three months ended April 30, 2011 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Approximately 27% of these costs were paid during the three months ended April 30, 2011. We expect to pay the remainder during the fiscal year ending January 31, 2012. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $252 for the three months ended April 30, 2011 were primarily due to the abandonment of leased facilities.

Other special charges for the three months ended April 30, 2011 included costs of $3,102 related to consulting fees associated with our proxy contest. Also included in other special charges for the three months ended April 30, 2011 was $46 representing legal and other costs related to acquisitions.

Employee severance and related costs of $1,589 for the three months ended April 30, 2010 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Substantially all of these costs were paid during the fiscal year ending January 31, 2011. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $474 for the three months ended April 30, 2010 were primarily due to the abandonment of leased facilities and changes in the estimate of sublease income for previously abandoned leased facilities.

Other special charges for the three months ended April 30, 2010 included costs of $1,175 related to advisory fees and other costs of $30.

Accrued special charges are included in accrued liabilities and other long-term liabilities in the condensed consolidated Balance Sheets. The following table shows changes in accrued special charges during the three months ended April 30, 2011:

	Accrued special charges as of January 31, 2011		Charges during the three months ended April 30, 2011		Payments during the three months ended April 30, 2011			Accrued special charges as of April 30, 2011 (1)
Employee severence and related costs	$	2,664	$	1,147	$	(1,587	)	$	2,224
Excess leased facility costs		1,930		252		(429	)		1,753
Other costs		2,336		3,148		(2,194	)		3,290
Total accrued special charges	$	6,930	$	4,547	$	(4,210	)	$	7,267

⁽¹⁾  Of the $7,267 total accrued special charges as of April 30, 2011, $1,113 represented the long-term portion of accrued lease termination fees and other facility costs, net of sublease income. The remaining balance of $6,154 represented the short-term portion of accrued special charges.

(15) Other Expense, Net—Other expense, net was comprised of the following:

Three months ended April 30,	2011			2010
Interest income	$	534		$	277
Foreign currency exchange gain (loss)		(651	)		(650	)
Other, net		(358	)		(768	)
Other expense, net	$	(475	)	$	(1,141	)

(16) Income Taxes—The provision for income taxes was comprised of the following:

Three months ended April 30,	2011		2010
Income tax expense	$	611	$	2,563

Generally, the provision for income taxes is the result of the mix of profits and losses earned by us and our subsidiaries in tax jurisdictions with a broad range of income tax rates, withholding taxes (primarily in certain foreign jurisdictions), changes in tax reserves, and the application of valuation allowances on deferred tax assets. Accounting guidance requires that on a quarterly basis we evaluate our provision for income tax expense (benefit) of U.S. and non-U.S. jurisdictions based on our projected results of operations for the full year and record an adjustment in the current quarter.

Three months ended April 30,	2011			2010
Effective Tax Rate		(35%)			(13%)
Period specific items expense (benefit)	$	(1,334	)	$	353

Without period specific items, our effective tax rate is (112%) for the three months ended April 30, 2011. Under our forecast of income for the year, we project a 12% effective tax rate with the inclusion of period specific items. Our effective tax rate differs from tax computed at the U.S. federal statutory rate of 35% primarily due to:

• The benefit of lower tax rates on earnings of foreign subsidiaries;

• Reduction in reserves for uncertain foreign tax positions; and

• The application of tax incentives for research and development in certain foreign jurisdictions.

These differences are partially offset by:

• U.S. losses for which no tax benefit has been recognized;

• Non-deductible employee stock purchase plan compensation expense; and

• Withholding taxes in certain foreign jurisdictions.

Actual results may differ significantly from our current projections. Further, on a quarterly basis, our effective tax rate could fluctuate considerably and could be adversely affected to the extent earnings are higher or lower than anticipated in countries where we have corresponding higher or lower statutory rates.

As of April 30, 2011, we had a liability of $42,422 for income taxes associated with uncertain income tax positions. All of these tax positions are classified as long-term liabilities in our condensed consolidated balance sheet. We are not able to reasonably estimate the timing of any cash payments required to settle these liabilities; however, we generally do not anticipate the settlement of the liabilities will require payment of cash within the next twelve months. We do not believe that the ultimate settlement of these liabilities will materially affect our liquidity. Further, certain liabilities may result in the reduction of deferred tax assets rather than settlement in cash.

(17) Related Party Transactions—Certain members of our Board of Directors also serve on the board of directors of certain of our customers. Management believes the transactions between these customers and us were carried out on an arm’s-length basis. The following table shows revenue recognized from these customers:

Three months ended April 30,	2011			2010
Revenue from customers	$	17,306		$	12,631
Percentage of total revenue		7.5	%		7.0	%

(18) Supplemental Cash Flow Information—The following provides information concerning supplemental disclosures of cash flow activities:

Three months ended April 30,	2011		2010
Cash paid, net for:
Interest	$	8,538	$	5,939
Income taxes	$	2,353	$	3,665

As part of the Valor acquisition in fiscal 2011, we acquired an investment in Frontline. During the three months ended April 30, 2011, we received returns on investment of $1,015 from Frontline which is included in net cash provided by operating activities in our condensed consolidated statement of cash flows.

(19) Segment Reporting—Our Chief Operating Decision Makers (CODMs), which consist of the Chief Executive Officer and the President, review our consolidated results within one operating segment. In making operating decisions, our CODMs primarily consider consolidated financial information accompanied by disaggregated revenue information by geographic region.

We eliminate all intercompany revenues in computing revenues by geographic regions. Revenues related to operations in the geographic regions were:

Three months ended April 30,	2011		2010
Revenues:
North America	$	90,323	$	65,165
Europe		52,197		42,577
Japan		41,634		31,668
Pacific Rim		45,881		41,167
Total revenues	$	230,035	$	180,577

For the three months ended April 30, 2011, one customer accounted for 21% of total revenues. No single customer accounted for 10% or more of total revenues for the three months ended April 30, 2010.

We segregate revenue into five categories of similar products and services. Each category includes both product and related support revenues. Revenue information is as follows:

Three months ended April 30,	2011		2010
Revenues:
IC Design to Silicon	$	86,288	$	71,532
Integrated System Design		51,545		44,591
Scalable Verification		58,742		36,737
New & Emerging Products		17,968		13,328
Services & Other		15,492		14,389
Total revenues	$	230,035	$	180,577

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Unless otherwise indicated, numerical references are in millions, except for percentages and per share data.

Overview

The following discussion should be read in conjunction with the condensed consolidated financial statements and notes included elsewhere in this Form 10-Q. Certain of the statements below contain forward-looking statements. These statements are predictions based upon our current expectations about future trends and events. Actual results could vary materially as a result of certain factors, including but not limited to, those expressed in these statements. In particular, we refer you to the risks discussed in Part II, Item 1A. “Risk Factors” and in our other Securities and Exchange Commission (SEC) filings, which identify important risks and uncertainties that could cause our actual results to differ materially from those contained in the forward-looking statements.

We urge you to consider these factors carefully in evaluating the forward-looking statements contained in this Form 10-Q. All subsequent written or spoken forward-looking statements attributable to our company or persons acting on our behalf are expressly qualified in their entirety by these cautionary statements. The forward-looking statements included in this Form 10-Q are made only as of the date of this Form 10-Q. We do not intend, and undertake no obligation, to update these forward-looking statements.

The Company

We are a supplier of electronic design automation (EDA) systems — advanced computer software and emulation hardware systems used to automate the design, analysis, and testing of electronic hardware and embedded systems software in electronic systems and components. We market our products and services worldwide, primarily to large companies in the military/aerospace, communications, computer, consumer electronics, semiconductor, networking, multimedia, and transportation industries. Through the diversification of our customer base among these various customer markets, we attempt to reduce our exposure to fluctuations within each market. We sell and license our products through our direct sales force and a channel of distributors and sales representatives. In addition to our corporate offices in Wilsonville, Oregon, we have sales, support, software development, and professional service offices worldwide.

We focus on products and design platforms where we have leading market share, enabling us to spend more effort to cause adoption of our technology in new applications, especially for new markets in which EDA companies have not participated. We believe this strategy leads to a more diversified product and customer mix and can help reduce the volatility of our business and our credit risk while increasing our potential for growth. System customers make up a much larger percentage of our business than that of most of our EDA competitors.

We derive system and software revenues primarily from the sale of term software license contracts, which are typically three to four years in length. We generally recognize revenue for these arrangements upon product delivery at the beginning of the license term. Larger enterprise-wide customer contracts, which can represent as much as 50% of our system and software revenue, drive the majority of our period-to-period revenue variances. We identify term licenses where collectibility is not probable and recognize revenue on those licenses when cash is received. Ratable license revenues also include short-term term licenses as well as other term licenses where we provide the customer with rights to unspecified or unreleased future products. For these reasons, the timing of large contract renewals, customer circumstances, and license terms are the primary drivers of revenue changes from period to period, with revenue changes also being driven by new contracts and increases in the capacity of existing contracts, to a lesser extent.

The EDA industry is competitive and is characterized by very strong leadership positions in specific segments of the EDA market. These strong leadership positions can be maintained for significant periods of time as the software can be difficult to master and customers are disinclined to make changes once their employees, as well as others in the industry, have developed familiarity with a particular software product. For these reasons, much of our profitability arises from areas in which we are the leader. We will continue our strategy of developing high quality tools with number one market share potential, rather than being a broad-line supplier with undifferentiated product offerings. This strategy allows us to focus investment in areas where customer needs are greatest and where we have the opportunity to build significant market share.

Our products and services are dependent to a large degree on new design projects initiated by customers in the integrated circuit and electronics system industries. These industries can be cyclical and are subject to constant and rapid technological change, rapid product obsolescence, price erosion, evolving standards, short product life cycles, and wide fluctuations in product supply and demand. Furthermore, extended economic downturns can result in reduced funding for development due to downsizing and other business restructurings. These pressures are offset by the need for the development and introduction of next generation products once an economic recovery occurs.

23

Our revenue has historically fluctuated quarterly and has generally been the highest in the fourth quarter of our fiscal year due to our customers’ corporate calendar year-end spending trends and the timing of contract renewals.

Known Trends and Uncertainties Impacting Future Results of Operations

Our top ten accounts make up approximately 40% of our receivables, including both short and long-term balances. We have not experienced and do not presently expect to experience collection issues with these customers. Net of reserves, we have no receivables greater than 60 days past due, and continue to experience no difficulty in factoring our high quality receivables.

Bad debt expense recorded for the three months ended April 30, 2011 was not material. However, we do have exposures within our receivables portfolio to customers with weak credit ratings. These receivables balances do not represent a material portion of our portfolio but could have a material adverse effect on earnings in any given quarter, should additional allowances for doubtful accounts be necessary.

A multi-quarter increase or decrease in service and support revenue can be an early indicator that our business is either strengthening or weakening. Our experience is that customers will scale back on the purchase of outside services in times of economic decline or weakness. In the first quarter of fiscal 2012 compared to the fourth quarter of fiscal 2011, software maintenance revenues were flat. During the fiscal year ended January 31, 2011, we noted an increase in software maintenance revenues.

Bookings during the first quarter of fiscal 2012 increased by approximately 5% compared to the first quarter of fiscal 2011. Bookings are the value of executed orders during a period for which revenue has been or will be recognized within six months for products and within twelve months for professional services and training. The ten largest transactions for the first quarter of fiscal 2012 accounted for approximately 40% of total system and software bookings compared to approximately 50% for the first quarter of fiscal 2011. The number of new customers during the first quarter of fiscal 2012, excluding PADS (our ready to use printed circuit board design tools) increased approximately 20% from the levels experienced during the first quarter of fiscal 2011.

We are focused on continued expense control in the operation of our business. We have plans to reduce sales, general, and administrative expenses as a percentage of revenue over the next three fiscal years.

Product Developments

During the three months ended April 30, 2011, we continued to execute our strategy of focusing on challenges encountered by customers, as well as building upon our well-established product families. We believe that customers, faced with leading-edge design challenges in creating new products, generally choose the best EDA products in each category to build their design environment. Through both internal development and strategic acquisitions, we have focused on areas where we believe we can build a leading market position or extend an existing leading market position.

We believe that the development and commercialization of EDA software tools is generally a three to five year process with limited customer adoption and sales in the first years of tool availability. Once tools are adopted, however, their life spans tend to be long. During the first quarter of fiscal 2012, we introduced new products and upgrades to existing products and did not have any significant products reaching the end of their useful economic life.

Critical Accounting Policies

We base our discussion and analysis of our financial condition and results of operations upon our condensed consolidated financial statements which have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We evaluate our estimates on an on-going basis. We base our estimates on historical experience, current facts, and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs, and expenses that are not readily apparent from other sources. As future events and their effects cannot be determined with precision, actual results could differ from those estimates.

We believe that the accounting for revenue recognition, valuation of trade accounts receivable, valuation of deferred tax assets, income tax reserves, goodwill, intangible assets, long-lived assets, special charges, and accounting for stock-based compensation are the critical accounting estimates and judgments used in the preparation of our condensed consolidated financial statements. For further discussion of our critical accounting policies, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies” in Part II of our Annual Report on Form 10-K for the year ended January 31, 2011.

System and software revenues	$	139.6			43	%	$	97.5
System and software gross margin	$	123.3			37	%	$	89.9
Gross margin percent		88	%					92	%
Service and support revenues	$	90.4			9	%	$	83.1
Service and support gross margin	$	66.2			9	%	$	60.8
Gross margin percent		73	%					73	%
Total revenues	$	230.0			27	%	$	180.6
Total gross margin	$	189.5			26	%	$	150.7
Gross margin percent		82	%					83	%

System and Software

Three months ended April 30,	2011		Change			2010
Upfront license revenues	$	118.3		65	%	$	71.5
Ratable license revenues		21.3		(18	%)		26.0
Total system and software revenues	$	139.6		43	%	$	97.5

We derive system and software revenues from the sale of licenses of software products and emulation hardware systems, including finance fee revenues from our long-term installment receivables resulting from product sales. Upfront license revenues consist of perpetual licenses and term licenses for which we recognize revenue upon product delivery at the start of a license term. We identify term licenses where collectability is not probable and recognize revenue on those licenses when cash is received. Additionally, ratable license revenues also include short-term term licenses, term licenses where we provide the customer with rights to unspecified or unreleased future products, and finance fees from the accretion of the discount on long-term installment receivables.

Our top ten customers accounted for approximately 60% of system and software revenues for the three months ended April 30, 2011 and approximately 45% for the three months ended April 30, 2010.

System and software revenues increased for the three months ended April 30, 2011 compared to the three months ended April 30, 2010 as a result of an increase in term license revenues of $23.5, driven by contract renewals during the three months ended April 30, 2011 compared to the three months ended April 30, 2010, an increase in perpetual license revenues of $17.5, primarily due to an increase in emulation revenues, and the effect of acquisitions completed in fiscal 2011 of $1.2.

For the three months ended April 30, 2011, one customer accounted for approximately 21% of total revenues. For the three months ended April 30, 2010, no single customer accounted for 10% or more of total revenues.

System and software gross margin percentage was lower for the three months ended April 30, 2011 compared to the three months ended April 30, 2010 primarily due to a change in product mix as a result of higher emulation hardware product revenues. Emulation hardware product revenues typically have lower margins compared to our software product revenues.

Amortization of purchased technology to system and software cost of revenues was $3.4 for the three months ended April 30, 2011 compared to $3.6 for the three months ended April 30, 2010.

Service and Support

We derive service and support revenues from software and hardware post-contract maintenance or support services and professional services, which includes consulting, training, and other services. Professional services are a lower margin offering which is staffed according to fluctuations in demand. Support services operate under a less variable cost structure.

The increase in service and support revenues for the three months ended April 30, 2011 compared to the three months ended April 30, 2010 was driven by increased support revenues of $4.2 resulting from of an increase in installed base, which included the effect of acquisitions completed in fiscal 2011 of $1.9. Consulting and training services increased by $2.4 for the three months ended April 30, 2011 compared to the three months ended April 30, 2010, primarily due to increased customer demand for services. The effect of acquisitions completed in fiscal 2011 for Consulting and training services for the three months ended April 30, 2011 compared to the three months ended April 30, 2010 was $0.9.

Geographic Revenues Information

Revenue by Geography

Three months ended April 30,	2011		Change			2010
North America	$	90.3		39	%	$	65.1
Europe		52.2		23	%		42.6
Japan		41.6		31	%		31.7
Pacific Rim		45.9		11	%		41.2
Total revenues	$	230.0		27	%	$	180.6

For the three months ended April 30, 2011, approximately one-fourth of European and all Japanese revenues were subject to exchange rate fluctuations as they were booked in local currencies. We recognize additional revenues in periods when the U.S. dollar weakens in value against foreign currencies. Likewise, we recognize lower revenues in periods when the U.S. dollar strengthens in value against foreign currencies.

Foreign currency had a favorable impact of $3.0 for the three months ended April 30, 2011 compared to the three months ended April 30, 2010 primarily due to the strengthening Japanese yen against the U.S. dollar.

For additional description of how changes in foreign exchange rates affect our condensed consolidated financial statements, see discussion in Part I, “Item 3. Quantitative and Qualitative Disclosures About Market Risk –Foreign Currency Risk.”

Operating Expenses

Three months ended April 30,	2011			Change			2010

Special charges		4.5			36	%		3.3
Total operating expenses	$	173.3			5	%	$	165.7

Selected Operating Expenses as a Percentage of Total Revenues

Three months ended April 30,	2011			2010
Research and development		30	%		36	%
Marketing and selling		33	%		41	%
General and administration		10	%		12	%
Total selected operating expenses		73	%		89	%

Research and Development

Research and development expenses increased by $5.8 for the three months ended April 30, 2011 compared to the three months ended April 30, 2010. The components of this increase are summarized as follows:

	Change for the three months ended April 30,
Salaries, variable compensation, and benefits expenses	$	4.3
Expenses associated with acquired businesses		2.4
Other expenses		(0.9	)
Total change in research and development expenses (1)	$	5.8

⁽¹⁾  The increase in expense for the three months ended April 30, 2011 compared to the three months ended April 30, 2010 includes approximately $3.2, which reflects a change in estimate associated with the allocation of salaries and related costs of our Technical Marketing Engineers (TMEs). Previously all of these costs were allocated to marketing and selling. We further refined our estimate based on research and development activities performed by the TMEs which includes development, code writing and testing.

26

Marketing and Selling

Marketing and selling expenses increased by $2.8 for the three months ended April 30, 2011 compared to the three months ended April 30, 2010. The components of this increase are summarized as follows:

	Change for the three months ended April 30,
Expenses associated with acquired businesses	$	2.4
Travel expenses		1.8
Other expenses		(1.4	)
Total change in marketing and selling expenses (1)	$	2.8

⁽¹⁾  The increase in expense for the three months ended April 30, 2011 compared to the three months ended April 30, 2010 includes a reduction of approximately $(3.2), which reflects a change in estimate associated with the allocation of salaries and related costs of our Technical Marketing Engineers (TMEs). See additional discussion regarding the change in estimate in the Research and Development analysis above.

General and Administration

General and administration expenses decreased by $0.6 for the three months ended April 30, 2011 compared to the three months ended April 30, 2010. There were no significant changes within General and administration expenses for the three months ended April 30, 2011 compared to the three months ended April 30, 2010.

We incur a substantial portion of our operating expenses outside the U.S. in various foreign currencies. When currencies weaken against the U.S. dollar, our operating expense performance is positively affected and when currencies strengthen, our operating expense performance is adversely affected. For the three months ended April 30, 2011 compared to the three months ended April 30, 2010, we experienced unfavorable currency movements of approximately $2.1 in total operating expenses. The impact of these currency movements is reflected in the movements in operating expenses detailed above.

Equity in Earnings of Frontline

In connection with our acquisition of Valor Computerized Systems, Ltd. (Valor) on March 18, 2010, we acquired Valor’s 50% interest in a joint venture, Frontline P.C.B. Solutions Limited Partnership (Frontline). Frontline is owned equally by Valor and Orbotech, Ltd., an Israeli company.

27

Frontline reports on a calendar year basis. As such, we record our interest in the earnings or losses of Frontline in the subsequent month following incurrence. The following presents the summarized financial information of Mentor’s 50% interest in Frontline for the three months ended March 31, 2011 and for the period from March 18, 2010 through March 31, 2010:

	For the three months ended March 31, 2011		For the period from March 18, 2010 through March 31, 2010
Net income-as reported	$	2.2	$	0.8
Amortization of purchased technology and other identified intangible assets		1.2		0.6
Equity in earnings of Frontline	$	1.0	$	0.2

Special Charges

Three months ended April 30,	2011		Change			2010
Employee severance and related costs	$	1.1		(31	%)	$	1.6
Excess leased facility costs		0.3		(40	%)		0.5
Other costs, net		3.1		158	%		1.2
Total special charges	$	4.5		36	%	$	3.3

Special charges primarily consist of costs incurred for employee terminations and were due to a reduction of personnel resources driven by modifications of business strategy or business emphasis. Special charges may also include expenses incurred related to potential acquisitions, excess facility costs, and asset-related charges.

Employee severance and related costs of $1.1 for the three months ended April 30, 2011 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Approximately 27% of the costs were paid during the three months ended April 30, 2011. We expect to pay the remainder during the fiscal year ending January 31, 2012. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $0.3 for the three months ended April 30, 2011 were primarily due to the abandonment of leased facilities.

Other special charges for the three months ended April 30, 2011 included costs of $3.1 related to consulting fees associated with our proxy contest.

Employee severance and related costs of $1.6 for the three months ended April 30, 2010 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which were individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local legal requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Substantially all of these costs were paid during the fiscal year ended January 31, 2011. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $0.5 for the three months ended April 30, 2010 were primarily due to the abandonment of leased facilities and changes in the estimate of sublease income for previously abandoned leased facilities.

Other special charges for the three months ended April 30, 2010 included costs of $1.2 related to advisory fees.

Interest Expense

Interest expense increased by $13.1 to $17.4 for the three months ended April 30, 2011 compared to $4.3 for the three months ended April 30, 2010. The increase was primarily due to the repayment of debt in April 2011 and the resulting losses of $11.5 on the early extinguishment of debt, which included a $6.2 write-off of the net unamortized debt discount, a $3.5 premium for the redemption of the 6.25% Debentures, and a write-off of $1.8 for the remaining portion of unamortized debt issuance costs.

Provision for Income Taxes

Our income tax expense for the three months ended April 30, 2011 was $0.6 compared to $2.6 for the same period in 2010. Generally, the provision for income taxes is the result of the mix of profits and losses earned by us and our subsidiaries in tax jurisdictions with a broad range of income tax rates, withholding taxes (primarily in certain foreign jurisdictions), changes in tax reserves, and the application of valuation allowances on deferred tax assets. Accounting guidance requires that on a quarterly basis we evaluate our provision for income tax expense (benefit) of U.S. and non-U.S. jurisdictions based on our projected results of operations for the full year and record an adjustment in the current quarter.

The effective tax rate for the three months ended April 30, 2011 was (35%), compared to (13%) for the same period in 2010, inclusive of period specific items. Without period specific items of ($1.3), our effective tax rate is (112%). We anticipate income for the year, resulting in a projected 12% effective tax rate with the inclusion of period specific items. Our effective tax rate differs from tax computed at the U.S. federal statutory rate of 35% primarily due to:

• The benefit of lower tax rates on earnings of foreign subsidiaries;

• Reduction in reserves for uncertain foreign tax positions; and

• The application of tax incentives for research and development in certain foreign jurisdictions;

These differences are partially offset by:

• U.S. losses for which no tax benefit has been recognized;

• Non-deductible employee stock purchase plan compensation expense; and

• Withholding taxes in certain foreign jurisdictions.

We have not provided for income taxes on the undistributed earnings of our foreign subsidiaries to the extent they are considered permanently reinvested outside of the U.S. Upon repatriation, some of these earnings may be sheltered by U.S. loss carryforwards, research and development credits and foreign tax credits, which may reduce the federal tax liability associated with any future foreign dividend. Determination of the amount of unrecognized deferred U.S. income tax liability on permanently reinvested foreign earnings is not practicable. To the extent that the earnings of our foreign subsidiaries are not treated as permanently reinvested, which include earnings of certain countries, we have considered the impact in our provision.

We determined deferred tax assets and liabilities based on differences between the financial reporting and tax basis of assets and liabilities. In addition, we record deferred tax assets for net operating loss carryforwards and tax credit carryforwards. We calculated the deferred tax assets and liabilities using the enacted tax rates and laws that will be in effect when we expect the differences to reverse. A valuation allowance is recorded when it is more likely than not that all or some portion of the deferred tax asset will not be realized. Since 2004, we have determined it is uncertain whether our U.S. entity will generate sufficient taxable income and foreign source income to utilize net operating loss carryforwards, research and experimentation credit carryforwards, and foreign tax credit carryforwards before expiration. Accordingly, we recorded a valuation allowance against those deferred tax assets for which realization does not meet the more likely than not standard. We have established valuation allowances related to certain foreign deferred tax assets based on historical losses as well as future expectations in certain jurisdictions. We will continue to evaluate the realizability of the deferred tax assets on a periodic basis.

We are subject to income taxes in the U.S. and in numerous foreign jurisdictions. In the ordinary course of business, there are many transactions and calculations where the ultimate tax determination is uncertain. The statute of limitations for adjustments to our historic tax obligations varies from jurisdiction to jurisdiction. In some cases it may be extended or be unlimited. Furthermore, net operating loss and tax credit carryforwards may be subject to adjustment after the expiration of the statute of limitations of the year such net operating losses and tax credits originated. Our larger jurisdictions generally provide for a statute of limitations from three to five years. We are currently under examination in various jurisdictions. The examinations are in different stages and timing of their resolution is difficult to predict. For U.S. federal income tax purposes, the tax years that remain open are fiscal year 2008 and forward.

29

We have reserves for taxes to address potential exposures involving tax positions that are being challenged or that could be challenged by taxing authorities even though we believe that the positions we have taken are appropriate. We believe our tax reserves are adequate to cover potential liabilities. We review the tax reserves quarterly and as circumstances warrant and adjust the reserves as events occur that affect our potential liability for additional taxes. It is often difficult to predict the final outcome or timing of resolution of any particular tax matter. Various events, some of which cannot be predicted, such as clarifications of tax law by administrative or judicial means, may occur and could require us to increase or decrease our reserves and effective tax rate. We expect to record additional reserves in future periods with respect to our tax filing positions. To the extent that uncertain tax positions resolve in our favor, it could have a positive impact on our effective tax rate.

LIQUIDITY AND CAPITAL RESOURCES

Our primary ongoing cash requirements are for product development, operating activities, capital expenditures, debt service, and acquisition opportunities that may arise. Our primary sources of liquidity are cash generated from operations and borrowings on our revolving credit facility.

As of April 30, 2011, we had cash and cash equivalents of $116.5. The available cash and cash equivalents are held in accounts managed by third-party financial institutions and consist of cash in our operating accounts.

Invested cash is held in interest bearing funds managed by third-party financial institutions. To date, we have experienced no loss or lack of access to our invested cash; however, we can provide no assurances that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial markets.

At any point in time, we have significant balances in operating accounts that are with individual third-party financial institutions, which may exceed the Federal Deposit Insurance Corporation insurance limits or other regulatory insurance program limits. While we monitor daily the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets.

We anticipate that the following will be sufficient to meet our working capital needs on a short-term (twelve months or less) and a long-term (more than twelve months) basis:

• Current cash balances;

• Anticipated cash flows from operating activities, including the effects of selling and financing customer term receivables;

• Amounts available under existing revolving credit facilities; and

• Other available financing sources, such as the issuance of debt or equity securities.

We have experienced no difficulties to date in raising debt. However, capital markets have been volatile, and we cannot assure you that we will be able to raise debt or equity capital on acceptable terms, if at all.

Three months ended April 30,	2011			2010
Cash provided by (used in) operating activities	$	(9.3	)	$	27.6
Cash used in investing activities	$	(8.4	)	$	(17.4	)
Cash provided by (used in) financing activities	$	0.3		$	(9.6	)

Operating Activities

Cash flows from operating activities consist of our net income (loss), adjusted for certain non-cash items and changes in operating assets and liabilities. For the three months ended April 30, 2011, our cash used in operating activities was primarily driven by incentive payments made during the quarter on fiscal 2011 year-end accruals, as discussed below. Our cash flows from operating activities are also significantly influenced by the payment terms on our license agreements and by our sales of qualifying accounts receivable. Our customers’ inability to fulfill payment obligations could adversely affect our cash flow. Though we have not, to date, experienced a material level of defaults, material payment defaults by our customers as a result of negative economic conditions or otherwise could have a material adverse effect on our financial condition. We monitor our accounts receivable portfolio for customers with low or declining credit ratings and increase our collection efforts when necessary.

Trade Accounts and Term Receivables

As of	April 30, 2011		January 31, 2011
Trade accounts receivable, net	$	321.0	$	347.1
Term receivables, long-term	$	179.0	$	167.4
Average days sales outstanding in short-term receivables		126 days		102 days
Average days sales outstanding in short-term receivable, net, excluding the current portion of term receivables		54 days		45 days

The increase in the average days sales outstanding in short-term receivables for the three months ended April 30, 2011 compared to the three months ended January 31, 2011 was due to a decrease in revenue in the first quarter of fiscal 2012 compared to the fourth quarter of fiscal 2011.

The current portion of term receivables was $182.0 as of April 30, 2011 and $193.3 as of January 31, 2011. Term receivables are attributable to multi-year term license sales agreements. We include amounts for term agreements that are due within one year in trade accounts receivable, net, and balances that are due in more than one year in term receivables, long-term. We use term agreements as a standard business practice and have a history of successfully collecting under the original payment terms without making concessions on payments, products, or services. Total term receivables were $361.0 as of April 30, 2011 compared to $360.8 as of January 31, 2011.

We enter into agreements to sell qualifying accounts receivable from time to time to certain financing institutions on a non-recourse basis. We received net proceeds from the sale of receivables of $11.4 for the three months ended April 30, 2011 compared to $14.9 for the three months ended April 30, 2010. We continue to have no difficulty in factoring receivables and continue to evaluate the economics of the sale of accounts receivable. We have not set a target for the sale of accounts receivables for the remainder of fiscal 2012.

Accrued Payroll and Related Liabilities

As of	April 30, 2011		January 31, 2011
Accrued payroll and related liabilities	$	58.6	$	109.2

The decrease in accrued payroll and related liabilities as of April 30, 2011 compared to January 31, 2010 was primarily due to incentive payments made during the quarter on fiscal 2011 year-end accruals. We generally experience higher accrued payroll and related liability balances at year end primarily due to increased commission accruals associated with an increase in revenues in the fourth quarter. Additionally, we generally experience an increase in variable compensation at year end which result from the full year achievement of results.

Deferred Revenue

As of	April 30, 2011		January 31, 2011
Deferred revenue	$	192.7	$	185.4

31

The increase in deferred revenue is primarily due to the addition of short-term software leases and an increase in current billings of support revenue and other services during the quarter ended April 30, 2011.

Investing Activities

Cash used in investing activities for the three months ended April 30, 2011 primarily consisted of cash paid for capital expenditures.

Expenditures for property, plant, and equipment decreased to $6.3 for the three months ended April 30, 2011 compared to $7.6 for the three months ended April 30, 2010. The expenditures for property, plant, and equipment for the three months ended April 30, 2011 were primarily a result of spending on information technology and infrastructure improvements within facilities. We expect total capital expenditures for property, plant, and equipment for fiscal 2012 to be approximately $50.0. We plan to finance our investments in property, plant, and equipment using cash on hand or borrowings on the revolving credit facility.

During the three months ended April 30, 2011, we acquired one privately held company. We plan to finance future business acquisitions through a combination of cash and common stock issuances. The cash expected to be utilized includes cash on hand, cash generated from operating activities, and borrowings on the revolving credit facility.

Financing Activities

For the three months ended April 30, 2011, cash provided by financing activities consisted primarily of proceeds from the issuance of the 4.00% Convertible Subordinated Debentures (4.00% Debentures) due 2031, offset in part by the redemption of the 6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026. Additional discussion regarding these notes payable are presented in the section below.

In April 2011, we announced a share repurchase program under which we may purchase up to $150.0 of our common stock over the three-year period through April 2014. During the three months ended April 30, 2011, we repurchased 1.7 shares of common stock for a total price of $25.0 utilizing proceeds received from the issuance of the 4.00% Debentures. Under the terms of our revolving credit facility, the amount we can repurchase under the remaining $125.0 of our share repurchase program is limited to $50.0 plus 70% of our cumulative net income for periods after January 31, 2011.

Other factors affecting liquidity and capital resources

4.00% Debentures due 2031

In April 2011, we issued $253,000 of the 4.00% Debentures. Interest on the 4.00% Debentures due 2031 is payable semi-annually in April and October. The 4.00% Debentures are convertible, under certain circumstances, into our common stock at a conversion price of $20.538 per share for a total of 12.3 shares as of April 30, 2011. Upon conversion of any 4.00% Debentures, a holder will receive:

(i) Cash up to the principal amount of the 4.00% Debentures that are converted; and

(ii) Cash or shares of common stock, at our election, for the excess, if any, of the value of the converted shares over the principal amount.

If a holder elects to convert their 4.00% Debentures in connection with a fundamental change in the company that occurs prior to April 5, 2016, the holder will also be entitled to receive a make whole premium upon conversion in some circumstances.

We may redeem some or all of the 4.00% Debentures for cash on or after April 5, 2016 at the following redemption prices expressed as a percentage of principal, plus any accrued and unpaid interest:

Period	Redemption Price
Beginning on April 5, 2016 and ending on March 31, 2017		101.143	%
Beginning on April 1, 2017 and ending on March 31, 2018		100.571	%
On April 1, 2018 and thereafter		100.000	%

The holders, at their option, may redeem the 4.00% Debentures in whole or in part for cash on April 1, 2018, April 1, 2021, and April 1, 2026, and in the event of a fundamental change in the company. In each case, the repurchase price will be 100% of the principal amount of the 4.00% Debentures plus any accrued and unpaid interest.

6.25% Debentures due 2026

Interest on the 6.25% Debentures was payable semi-annually in March and September. During April 2011, we redeemed the remaining $196.5 principal amount of the 6.25% Debentures utilizing proceeds received from the issuance of the 4.00% Debentures and cash on hand. In connection with this redemption, during the three months ended April 30, 2011, we

32

incurred a before tax net loss on the early extinguishment of debt of $11.2, which included a $6.2 write-off of the net unamortized debt discount, a $3.5 premium on the redemption of the 6.25% Debentures, and a write-off of $1.5 for the remaining portion of unamortized debt issuance costs. No balance remains outstanding following this redemption.

Term Loan due 2013

In April 2010, we entered into a three-year term loan (Term Loan) to repay borrowings under our revolving credit facility used to purchase office buildings in Fremont, California. A fixed principal amount of $0.5 and interest payments were payable quarterly in February, May, August, and November.

In April 2011, we repaid the remaining $18.5 utilizing proceeds received from the issuance of the 4.00% Debentures. No balance remains outstanding following this repayment.

For further information on the 4.00% Debentures, 6.25% Debentures, and the Term Loan, see Note 8. “Notes Payable” in Part I, Item 1. “Financial Statements.”

Revolving Credit Facility

In April 2011, we entered into a syndicated, senior, unsecured, four-year revolving credit facility with a maximum borrowing capacity of $125.0. We have the option to pay interest on this revolving credit facility based on:

(i) London Interbank Offered Rate (LIBOR) with varying maturities which are commensurate with the borrowing period we select, plus a spread of between 2.25% and 3.25% based on a pricing grid tied to a financial covenant; or

(ii) A base rate plus a spread of between 1.25% and 2.25%, based on a pricing grid tied to a financial covenant.

The base rate is defined as the highest of:

(i) The federal funds rate, as defined, plus 0.5%;

(ii) The prime rate of the lead bank; or

(iii) One-month LIBOR plus 1.0%.

As a result of these interest rate options, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. In addition, commitment fees are payable on the unused portion of the revolving credit facility at rates between 0.40% and 0.50% based on a pricing grid tied to a financial covenant.

We had no borrowings against the revolving credit facility during the three months ended April 30, 2011. The base interest rate was 4.50% as of April 30, 2011.

For further information on our revolving credit facility, see Note 7. “Short-Term Borrowings” in Part I, Item 1. “Financial Statements.”

OFF-BALANCE SHEET ARRANGEMENTS

We do not have off-balance sheet arrangements, financings, or other similar relationships with unconsolidated entities or other persons, also known as special purpose entities. In the ordinary course of business, we lease certain real properties, primarily field sales offices, research and development facilities, and equipment.

OUTLOOK FOR FISCAL 2012

We expect revenues for the second quarter of fiscal 2012 to be approximately $210 with loss per share for the same period of approximately $(0.05) per diluted share. For the full fiscal year 2012, we expect revenues of approximately $1,004 with earnings per share of $0.67 per diluted share.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Unless otherwise indicated, all numerical references in tables are in millions, except interest rates and contract rates.

Interest Rate Risk

We are exposed to interest rate risk primarily through our investment portfolio, short-term borrowings, and notes payable. We do not use derivative financial instruments for speculative or trading purposes.

We place our investments in instruments that meet high quality credit standards, as specified in our investment policy. The policy also limits the amount of credit exposure to any one issuer and type of instrument. We do not expect any material loss with respect to our investment portfolio.

The table below presents the carrying amount and related weighted-average fixed interest rates for our investment portfolio. The carrying amount approximates fair value as of April 30, 2011. In accordance with our investment policy, all short-term investments mature in twelve months or less.

Principal (notional) amounts in United States dollars	Carrying Amount		Average Fixed Interest Rate
Cash equivalents – fixed rate	$	6.0		0.01	%

We had convertible subordinated debentures with a principal balance of $253.0 outstanding with a fixed interest rate of 4.00% as of April 30, 2011 compared to a principal balance of $165.0 with a fixed interest rate of 6.25% as of April 30, 2010. Interest rate changes for fixed rate debt affect the fair value of the debentures but do not affect future earnings or cash flow.

As of April 30, 2011, we had a syndicated, senior, unsecured, revolving credit facility, which expires on April 27, 2015. Borrowings under the revolving credit facility are permitted to a maximum of $125.0. Under this revolving credit facility, we have the option to pay interest based on:

(i) LIBOR with varying maturities which are commensurate with the borrowing period we select, plus a spread of between 2.25% and 3.25%; or

(ii) A base rate plus a spread of between 1.25% and 2.25%, based on a pricing grid tied to a financial covenant.

The base rate is defined as the highest of:

(i) The federal funds rate, as defined, plus 0.5%;

(ii) The prime rate of the lead bank; or

(iii) One-month LIBOR plus 1.0%.

As a result of these interest rate options, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. This revolving credit facility contains certain financial and other covenants, including financial covenants requiring the maintenance of specified liquidity ratios, leverage ratios, and minimum tangible net worth as well as restrictions on the payment of dividends. As of April 30, 2011 and 2010, we had no balance outstanding against this revolving credit facility. Interest rate changes for variable interest rate debt generally do not affect the fair market value, but do affect future earnings and cash flow. For further information on our revolving credit facility, see Note 7. “Short-Term Borrowings” in Part I, Item 1. “Financial Statements.”

We had other short-term borrowings of $4.9 outstanding as of April 30, 2011 and $4.3 as of April 30, 2010 with variable rates based on market indexes. Interest rate changes for variable interest rate debt generally do not affect the fair market value, but do affect future earnings and cash flow.

If the interest rates as of April 30, 2011 on the above variable rate borrowings were to increase or decrease by 1% and the level of borrowings outstanding remained constant, annual interest expense would increase or decrease by approximately $0.1.

Foreign Currency Risk

We transact business in various foreign currencies and have established a foreign currency hedging program to hedge certain foreign currency forecasted transactions and exposures from existing assets and liabilities. Our derivative instruments consist of short-term foreign currency exchange contracts, with a duration period of a year or less. We enter into contracts with counterparties who are major financial institutions and, as such we do not expect material losses as a result of defaults by our counterparties. We do not hold or issue derivative financial instruments for speculative or trading purposes.

34

We enter into foreign currency forward contracts to protect against currency exchange risk associated with expected future cash flows. Our practice is to hedge a majority of our existing material foreign currency transaction exposures, which generally represent the excess of expected euro and British pound denominated expenses over expected euro and British pound denominated revenues, and the excess of Japanese yen denominated revenue over expected Japanese yen denominated expenses. We also enter into foreign currency forward contracts to protect against currency exchange risk associated with existing assets and liabilities.

The following table provides volume information about our foreign currency forward program. The information provided is in U.S. dollar equivalent amounts. The table presents the gross notional amounts, at contract exchange rates, and the weighted average contractual foreign currency exchange rates. These forward contracts mature within the next twelve months.

Item 4. Controls and Procedures

(1) Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (Exchange Act), that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of the end of the period covered by this report.

(2) Changes in Internal Controls Over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1A. Risk Factors

The forward-looking statements contained under “Outlook for Fiscal 2012” in Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and all other statements contained in this report that are not statements of historical fact, including without limitation, statements containing the words “believes,” “expects,” “projections,” and words of similar meaning, constitute forward-looking statements that involve a number of risks and uncertainties that are difficult to predict. Moreover, from time to time, we may issue other forward-looking statements. Forward-looking statements regarding financial performance in future periods, including the statements under “Outlook for Fiscal 2012,” do not reflect potential impacts of mergers or acquisitions or other significant transactions or events that have not been announced as of the time the statements are made. Actual outcomes and results may differ materially from what is expressed or forecast in forward-looking statements. We disclaim any obligation to update forward-looking statements to reflect future events or revised expectations. Our business faces many risks, and set forth below are some of the factors that could cause actual results to differ materially from the results expressed or implied by our forward-looking statements. Forward-looking statements should be considered in light of these factors.

Weakness in the United States (U.S.) and international economies may harm our business.

Our revenue levels are generally dependent on the level of technology capital spending, which includes worldwide expenditures for electronic design automation (EDA) software, hardware, and consulting services. Periods of economic uncertainty, such as the recession experienced in 2008 and much of 2009, can adversely affect our customers and postpone decisions to license or purchase our products, decrease our customers’ spending, and jeopardize or delay our customers’ ability or willingness to make payment obligations, any of which could adversely affect our business.

Our forecasts of our revenues and earnings outlook may be inaccurate.

Our revenues, particularly new software license revenues, are difficult to forecast. We use a “pipeline” system, a common industry practice, to forecast revenues and trends in our business. Sales personnel monitor the status of potential business and estimate when a customer will make a purchase decision, the dollar amount of the sale, and the products or services to be sold. These estimates are aggregated periodically to generate a sales pipeline. Our pipeline estimates may prove to be unreliable either in a particular quarter or over a longer period of time, in part because the “conversion rate” of the pipeline into contracts can be very difficult to estimate and requires management judgment. A variation in the conversion rate could cause us to plan or budget incorrectly and materially adversely impact our business or our planned results of operations. In particular, a slowdown in customer spending or weak economic conditions generally can reduce the conversion rate in a particular quarter as purchasing decisions are delayed, reduced in amount, or cancelled. The conversion rate can also be affected by the tendency of some of our customers to wait until the end of a fiscal quarter attempting to obtain more favorable terms. This may result in failure to agree to terms within the fiscal quarter and cause expected revenue to slip into a subsequent quarter.

Our business could be impacted by fluctuations in quarterly results of operations due to customer seasonal purchasing patterns, the timing of significant orders, and the mix of licenses and products purchased by our customers.

We have experienced, and may continue to experience, varied quarterly operating results. Various factors affect our quarterly operating results and some of these are not within our control, including customer demand and the timing of significant orders. We typically experience seasonality in demand for our products, due to the purchasing cycles of our customers, with revenues in the fourth quarter generally being the highest. If planned contract renewals are delayed or the average size of renewed contracts do not increase as we anticipate, we could fail to meet our and investors’ expectations, which could have a material adverse impact on our stock price.

Our revenues are also affected by the mix of licenses entered into where we recognize software revenues as payments become due and payable, on a cash basis, or ratably over the license term as compared to revenues recognized at the beginning of the license term. We recognize revenues ratably over the license term, for instance, when the customer is provided with rights to unspecified or unreleased future products. A shift in the license mix toward increased ratable, due and payable, and/or cash-based revenue recognition could result in increased deferral of software revenues to future periods and would decrease current revenues, which could result in us not meeting near-term revenue expectations.

The gross margin on our software is greater than that for our emulation hardware systems, software support, and professional services. Therefore, our gross margin may vary as a result of the mix of products and services sold. We also have a significant amount of fixed or relatively fixed costs, such as employee costs and purchased technology amortization, and costs which are committed in advance and can only be adjusted periodically. As a result, a small failure to reach planned revenues would likely have a relatively large negative effect on resulting earnings. If anticipated revenues do not materialize as expected, our gross margins and operating results could be materially adversely impacted.

37

We face intense price competition in the EDA industry.

Price competition in the EDA industry is intense, which can lead to, among other things, price reductions, longer selling cycles, lower product margins, loss of market share, and additional working capital requirements. If our competitors offer significant discounts on certain products, we may need to lower our prices or offer other favorable terms to compete successfully. Any such changes would likely reduce margins and could materially adversely impact our operating results. Any broad-based changes to our prices and pricing policies could cause new software license and service revenues to decline or be delayed as the sales force implements and our customers adjust to the new pricing policies. Some of our competitors may bundle certain software products at low prices for promotional purposes or as a long-term pricing strategy. These practices could significantly reduce demand for our products or limit prices we can charge.

We currently compete primarily with two large companies: Synopsys, Inc. and Cadence Design Systems, Inc. We also compete with smaller companies and compete with manufacturers of electronic devices that have developed their own EDA products internally. Some large customers may also develop internal tools, thereby reducing demand for our products.

Foreign currency fluctuations may have an adverse impact on our operating results.

We typically generate about half of our revenues from customers outside the U.S. and we generate approximately one-third of our expenses outside the U.S. While most of our international sales are denominated in U.S. dollars, our international operating expenses are typically denominated in foreign currencies. Significant changes in currency exchange rates, particularly in the Japanese yen, euro, and the British pound, could have an adverse impact on our operating results.

Our international operations involve risks that could increase our expenses, adversely affect our operating results, and require increased time and attention of our management.

Our international operations subject us to risks in addition to those we face in our domestic operations, including longer receivables collection periods, changes in a specific country’s or region’s economic or political conditions, trade protection measures, local labor laws, import or export licensing requirements, anti-corruption and other similar laws, loss or modification of exemptions for taxes and tariffs, limitations on repatriation of earnings, and difficulties with licensing and protecting our intellectual property rights. If we violate applicable laws related to our business, we could be subject to penalties, fines, or other sanctions and could be prohibited or limited from doing business in one or more countries.

We derive a substantial portion of our revenues from relatively few product groups.

We derive a substantial portion of our revenues from sales of relatively few product groups and related support services. As a result, any factor adversely affecting sales of these products, including the product release cycles, market acceptance, product competition, performance and reliability, reputation, price competition, and economic and market conditions, could harm our operating results.

We are subject to the cyclical nature of the integrated circuit (IC) and electronics systems industries.

Purchases of our products and services are highly dependent upon new design projects initiated by customers in the IC and electronics systems industries. These industries are highly cyclical and are subject to constant and rapid technological change, rapid product obsolescence, price erosion, evolving standards, short product life cycles, and wide fluctuations in product supply and demand. The increasing complexity of ICs and resulting increase in costs to design and manufacture ICs have in recent years led to fewer design starts, which could cause a reduced demand for our products. In addition, the IC and electronics systems industries regularly experience significant downturns, often connected with, or in anticipation of, maturing product cycles within such companies or decline in general economic conditions. These downturns could cause diminished demand for our products and services.

Shortages of components for our hardware products may delay or reduce our sales and increase our costs.

The inability to obtain sufficient quantities of components and other materials necessary for the production of our hardware products could result in reduced or delayed sales or lost orders. Any delay in or loss of sales could adversely impact our operating results. From time to time, materials and components used in our production or in other aspects of our customers’ products may become subject to allocation because of shortages of these materials and components. Future shortages of materials and components, including potential supply constraints of silicon, could cause delayed shipments, customer dissatisfaction, and lower revenue.

Customer payment defaults could adversely affect our timing of revenue recognition.

We use fixed-term license agreements as standard business practices with customers we believe are creditworthy. These multi-year, multi-element term license agreements have payments spread over the license term and are typically about three years in length for semiconductor companies and about four years in length for military and aerospace companies. The complexity of these agreements tends to increase the risk associated with collectibility from customers that can arise for a

38

variety of reasons including ability to pay, product dissatisfaction, and disputes. If we are unable to collect under these agreements, our results of operations could be materially adversely impacted. We use these fixed-term license agreements as a standard business practice and have a history of successfully collecting under the original payment terms without making concessions on payments, products, or services. If we no longer had a history of collecting without providing concessions on the terms of the agreements, then revenue would be required to be recognized under U.S. generally accepted accounting principles as the payments become due and payable over the license term. This change could have a material adverse impact on our near-term results.

IC and printed circuit board (PCB) technology evolves rapidly.

The complexity of ICs and PCBs continues to rapidly increase. In response to this increasing complexity, new design tools and methodologies must be invented or acquired quickly to remain competitive. If we fail to quickly respond to new technological developments, our products could become obsolete or uncompetitive, which could materially adversely impact our business.

Errors or defects in our products and services could expose us to liability and harm our reputation.

Our customers use our products and services in designing and developing products that involve a high degree of technological complexity and have unique specifications. Due to the complexity of the systems and products with which we work, some of our products and designs can be adequately tested only when put to full use in the marketplace. As a result, our customers or their end users may discover errors or defects in our software, or the products or systems designed with or manufactured using tools that may not operate as expected. Errors or defects could result in:

• Loss of current customers and loss of, or delay in, revenue and loss of market share;

• Failure to attract new customers or achieve market acceptance;

• Diversion of development resources to resolve the problems resulting from errors or defects; and

• Increased support or service costs.

In addition, we include limited amounts of third-party technology in our products and we rely on those third parties to provide support services to us. Failure of those third parties to provide necessary support services could materially adversely impact our business.

Long sales cycles and delay in customer completion of projects make the timing of our revenues difficult to predict.

We have a lengthy sales cycle. A lengthy customer evaluation and approval process is generally required due to the complexity and expense associated with our products and services. Consequently, we may incur substantial expenses and devote significant management effort and expense to develop potential relationships that do not result in agreements or revenues and may prevent us from pursuing other opportunities. In addition, sales of our products and services is sometimes discretionary and may be delayed if customers delay approval or commencement of projects due to budgetary constraints, internal acceptance review procedures, timing of budget cycles, or timing of competitive evaluation processes.

Any loss of our leadership position in certain segments of the EDA market could harm our business.

The industry in which we compete is characterized by very strong leadership positions in specific segments of the EDA market. For example, one company may have a large percentage of sales in the physical verification segment of the market while another may have a similarly strong position in mixed-signal simulation. These strong leadership positions can be maintained for significant periods of time as the software is difficult to master and customers are disinclined to make changes once their employees, as well as others in the industry, have developed familiarity with a particular software product. For these reasons, much of our profitability arises from niche areas in which we are the leader. Conversely, it is difficult for us to achieve significant profits in niche areas where other companies are the leaders. If for any reason we lose our leadership position in a niche, we could be materially adversely impacted.

Accounting rules governing revenue recognition are complex and may change.

The accounting rules governing software revenue recognition are complex and have been subject to authoritative interpretations that have generally made it more difficult to recognize software revenues at the beginning of the license period.

39

We may have additional tax liabilities.

Significant judgments and estimates are required in determining the provision for income taxes and other tax liabilities. Our tax expense may be impacted if our intercompany transactions, which are required to be computed on an arm’s-length basis, are challenged and successfully disputed by the tax authorities. Also, our tax expense could be impacted depending on the applicability of withholding taxes on software licenses and related intercompany transactions in certain jurisdictions. In determining the adequacy of income taxes, we assess the likelihood of adverse outcomes resulting from the Internal Revenue Service (IRS) and other tax authorities’ examinations. The tax authorities in the U.S. and its various states and in countries where we do business regularly examine our tax returns. The ultimate outcome of these examinations cannot be predicted with certainty. Should the tax authorities assess additional taxes as a result of examinations, we may be required to record charges to operations that could have a material impact on the results of operations, financial position, or cash flows.

Forecasting our income tax rate is complex and subject to uncertainty.

The computation of income tax expense (benefit) is complex as it is based on the laws of numerous taxing jurisdictions and requires significant judgment on the application of complicated rules governing accounting for tax provision under U.S. generally accepted accounting principles. Income tax expense (benefit) for interim quarters is based on a forecast of our U.S. and non-U.S. effective tax rates for the year, which includes forward looking financial projections, including the expectations of profit and loss by jurisdiction, and contains numerous assumptions. Various items cannot be accurately forecasted, and may be treated as discrete accounting. Examples of items which could cause variability in the rate include tax deductions for stock option expense, application of transfer pricing rules, and changes in our valuation allowance for deferred tax assets. Future events, such as changes in our business and the tax law in the jurisdictions where we do business, could also affect our U.S. and non-U.S. effective rates. For these reasons, our overall global tax rate may be materially different than our forecast.

There are limitations on the effectiveness of controls.

We do not expect that disclosure controls or internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Failure of our control systems to prevent error or fraud could materially adversely impact us.

We may not realize revenues as a result of our investments in research and development.

We incur substantial expense to develop new software products. Research and development activities are often performed over long periods of time. This effort may not result in a successful product offering because of either a change in market conditions or a failure to successfully develop products based on that research and development activity. As a result, we could realize little or no revenues related to our investment in research and development.

We may acquire other companies and may not successfully integrate them.

The industry in which we compete has experienced significant consolidation in recent years. During this period, we have acquired numerous businesses and have frequently been in discussions with potential acquisition candidates, and we may acquire other businesses in the future. While we expect to carefully analyze all potential transactions before committing to them, we cannot assure that any completed transaction will result in long-term benefits to us or our shareholders or that we will be able to manage the acquired businesses effectively. In addition, growth through acquisition involves a number of risks. If any of the following events occurs after we acquire another business, it could materially adversely impact us:

• Difficulties in combining previously separate businesses into a single unit;

• The substantial diversion of management’s attention from ongoing business when integrating the acquired business;

• The failure to realize anticipated benefits, such as cost savings and increases in revenues;

• The failure to retain key personnel of the acquired business;

• Difficulties related to assimilating the products of an acquired business in, for example, distribution, engineering, and customer support areas;

• Unanticipated costs;

• Unanticipated liabilities or litigation in connection with or as a result of an acquisition, including claims from terminated employees, customers, or third parties;

40

• Adverse impacts on existing relationships with suppliers and customers; and

• Failure to understand and compete effectively in markets in which we have limited experience.

Acquired businesses may not perform as projected, which could result in impairment of acquisition-related intangible assets. Additional challenges include integration of sales channels, training and education of the sales force for new product offerings, integration of product development efforts, integration of systems of internal controls, and integration of information systems. Accordingly, in any acquisition there will be uncertainty as to the achievement and timing of projected synergies, cost savings, and sales levels for acquired products. All of these factors could impair our ability to forecast, meet revenues and earnings targets, and manage effectively our business for long-term growth. We cannot assure that we can effectively meet these challenges.

We may not adequately protect our proprietary rights or we may fail to obtain software or other intellectual property licenses.

Our success depends, in large part, upon our proprietary technology. We generally rely on patents, copyrights, trademarks, trade secret laws, licenses, and restrictive agreements to establish and protect our proprietary rights in technology and products. Despite precautions we may take to protect our intellectual property, we cannot assure that third parties will not try to challenge, invalidate, or circumvent these protections. The companies in the EDA industry, as well as entities and persons outside the industry, are obtaining patents at a rapid rate. We cannot predict if any of these patents will cover any of our products. In addition, many of these entities have substantially larger patent portfolios than we have. As a result, we may on occasion be forced to engage in costly patent litigation to protect our rights or defend our customers’ rights. We may also need to settle these claims on terms that are unfavorable; such settlements could result in the payment of significant damages or royalties, or force us to stop selling or redesign one or more products. We cannot assure that the rights granted under our patents will provide us with any competitive advantage, that patents will be issued on any of our pending applications, or that future patents will be sufficiently broad to protect our technology. Furthermore, the laws of foreign countries may not protect our proprietary rights in those countries to the same extent as U.S. law protects these rights in the U.S.

Some of our products include software or other intellectual property licensed from third parties, and we may have to seek new licenses or renew existing licenses for software and other intellectual property in the future. Failure to obtain software or other intellectual property licenses or rights from third parties on favorable terms could materially adversely impact us.

Our use of open source software could negatively impact our ability to sell our products and may subject us to unanticipated obligations.

The products, services or technologies we acquire, license, provide or develop may incorporate or use open source software. We monitor our use of open source software in an effort to avoid unintended consequences, such as reciprocal license grants, patent retaliation clauses, and the requirement to license our products at no cost. Nevertheless, we may be subject to unanticipated obligations regarding our products which incorporate open source software.

Our failure to attract and retain key employees may harm us.

We depend on the efforts and abilities of our senior management, our research and development staff, and a number of other key management, sales, support, technical, and services personnel. Competition for experienced, high-quality personnel is intense, and we cannot assure that we can continue to recruit and retain such personnel. Our failure to hire and retain such personnel could impair our ability to develop new products and manage our business effectively.

We have global sales and research and development offices in parts of the world that are not as politically stable as the United States.

We have global sales and research and development offices, some of which are in parts of the world that are not as politically stable as the United States. In particular our offices in Egypt and Pakistan may be subject to disruption or closure from time to time. As a result, we may face a greater risk of business interruption as a result of potential unrest, terrorist acts, or military conflicts than businesses located domestically.

Oregon law and our shareholder rights plan may have anti-takeover effects.

The Oregon Business Combination Act limits the ability of parties who acquire a significant amount of voting stock to exercise control over us. This provision may have the effect of lengthening the time required to acquire control of us through a proxy contest or the election of a majority of the Board of Directors. In June 2010, we adopted a shareholder rights plan, which has the effect of making it more difficult for a person to acquire control of us in a transaction not approved by our board of directors. The provisions of the Oregon Business Combination Act and our shareholder rights plan could have the effect of delaying, deferring, or preventing a change of control of us, could discourage bids for our common stock at a premium over the market price of our common stock and could materially adversely impact the market price of, and the voting and other rights of the holders of, our common stock.

41

Our revolving credit facility has financial and non-financial covenants, and default of any covenant could materially adversely impact us.

Our bank revolving credit facility imposes operating restrictions on us in the form of financial and non-financial covenants. Financial covenants include adjusted quick ratio, tangible net worth, leverage ratio, senior leverage ratio, and minimum cash and accounts receivable ratio. If we were to fail to comply with the financial covenants and did not obtain a waiver from our lenders, we would be in default under the revolving credit facility and our lenders could terminate the facility and demand immediate repayment of all outstanding loans under the revolving credit facility. The declaration of an event of default could have a material adverse effect on our financial condition. We could also find it difficult to obtain other bank lines or credit facilities on comparable terms.

We have a substantial level of indebtedness.

As of April 30, 2011, we had $263.4 million of outstanding indebtedness, which includes $253.0 million of 4.00% Convertible Subordinated Debentures (4.00% Debentures) due 2031, $1.3 in other notes payable, and $9.1 million in short-term borrowings. This level of indebtedness among other things could:

• Make it difficult for us to satisfy our payment obligations on our debt;

• Make it difficult for us to incur additional indebtedness or obtain any necessary financing in the future for working capital, capital expenditures, debt service, acquisitions, or general corporate purposes;

• Limit our flexibility in planning for or reacting to changes in our business;

• Reduce funds available for use in our operations;

• Make us more vulnerable in the event of a downturn in our business; and

• Place us at a possible competitive disadvantage relative to less leveraged competitors and competitors that have greater access to capital resources.

We may also be unable to borrow funds as a result of an inability of financial institutions to lend due to restrictive lending policies and/or institutional liquidity concerns.

If we experience a decline in revenues, we could have difficulty paying amounts due on our indebtedness. Any default under our indebtedness could have a material adverse impact on our business, operating results, and financial condition.

Our stock price could become more volatile, and your investment could lose value.

All of the factors discussed in this “Risk Factors” section could affect our stock price. The timing of announcements in the public market regarding new products, product enhancements, or technological advances by our competitors or us, and any announcements by us of acquisitions, major transactions, or management changes could also affect our stock price. Our stock price is subject to speculation in the press and the analyst community, changes in recommendations or earnings estimates by financial analysts, changes in investors’ or analysts’ valuation measures for our stock, our credit ratings, and market trends unrelated to our performance. A significant drop in our stock price could also expose us to the risk of securities class actions lawsuits, which could result in substantial costs and divert management’s attention and resources, which could adversely affect our business.

Our business could be negatively affected as a result of actions of activist shareholders.

Responding to actions by activist shareholders can be costly and time-consuming, disrupting our operations and diverting the attention of management and our employees. The perceived uncertainties as to our future direction may result in the loss of potential business opportunities, and may make it more difficult to attract and retain qualified personnel and business partners.

Short-Term Borrowings

Short-Term Borrowings

(7) Short-Term Borrowings—Short-term borrowings consisted of the following:

As of	April 30, 2011		January 31, 2011
Collections of previously sold accounts receivable	$	4,143	$	10,680
Other borrowings		4,912		4,864
Short-term borrowings	$	9,055	$	15,544

In April 2011, we entered into a syndicated, senior, unsecured, four-year revolving credit facility that terminates April 27, 2015. The revolving credit facility has a maximum borrowing capacity of $125,000. Under this revolving credit facility, we have the option to pay interest based on:

(i) London Interbank Offered Rate (LIBOR) with varying maturities commensurate with the borrowing period we select, plus a spread of between 2.25% and 3.25% based on a pricing grid tied to a financial covenant, or

(ii) A base rate plus a spread of between 1.25% and 2.25%, based on a pricing grid tied to a financial covenant.

The base rate is defined as the highest of:

(i) The federal funds rate, as defined, plus 0.5%,

(ii) The prime rate of the lead bank, or

(iii) One-month LIBOR plus 1.0%.

As a result of these interest rate options, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. In addition, commitment fees are payable on the unused portion of the revolving credit facility at rates between 0.40% and 0.50% based on a pricing grid tied to a financial covenant. We paid commitment fees as follows:

Three months ended April 30,	2011		2010
Commitment fees	$	80	$	66

This revolving credit facility contains certain financial and other covenants, including the following:

• Our adjusted quick ratio (ratio of the sum of cash and cash equivalents, short-term investments, and net current receivables to total current liabilities) shall not be less than 1.00;

• Our tangible net worth (stockholders’ equity less goodwill and other intangible assets) must exceed the calculated required tangible net worth as defined in the credit agreement, which establishes a fixed level of required tangible net worth. Each quarter the required level increases by 70% of any positive net income in the quarter (but in the aggregate no more than 70% of positive net income for any full fiscal year), 100% of the amortization of intangible assets in the quarter, and 100% of certain stock issuance proceeds. The required level also decreases each quarter by 50% of amounts paid for dividends or repurchases of our stock and certain amounts of acquired intangible assets;

• Our leverage ratio (ratio of total liabilities less subordinated debt to the sum of subordinated debt and tangible net worth) shall be less than 2.00;

• Our senior leverage ratio (ratio of total debt less subordinated debt to the sum of subordinated debt and tangible net worth) shall not be greater than 0.90; and

• Our minimum cash and accounts receivable ratio (ratio of the sum of cash and cash equivalents, short-term investments, and 42.0% of net current accounts receivable, to outstanding credit agreement borrowings) shall not be less than 1.25.

The revolving credit facility limits the aggregate amount we can pay for dividends and repurchases of our stock over the four year term of the facility to $50,000 plus 70% of our cumulative net income.

We were in compliance with all financial covenants as of April 30, 2011. If we were to fail to comply with the financial covenants and do not obtain a waiver from our lenders, we would be in default under the revolving credit facility and our lenders could terminate the facility and demand immediate repayment of all outstanding loans under the revolving credit facility.

Short-term borrowings include amounts collected from customers on accounts receivable previously sold on a non-recourse basis to financial institutions. These amounts are remitted to the financial institutions in the following quarter.

We generally have other short-term borrowings, including multi-currency lines of credit, capital leases, and other borrowings. Interest rates are generally based on the applicable country’s prime lending rate, depending on the currency borrowed.

Net Loss Per Share

3 Months Ended

Apr. 30, 2011

Net Loss Per Share

(12) Net Loss Per Share—We compute basic net loss per share using the weighted average number of common shares outstanding during the period. We compute diluted net loss per share using the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of common shares issuable upon exercise of stock options, restricted stock units, purchase rights from ESPPs, and warrants using the treasury stock method and common shares issuable upon conversion of the convertible subordinated debentures, if dilutive.

The following provides the computation of basic and diluted net loss per share:

	Three months ended April 30,
	2011			2010
Net loss	$	(2,353	)	$	(23,025	)
Weighted average common shares used to calculate basic and diluted net loss per share		111,769			103,763
Basic and diluted net loss per share	$	(0.02	)	$	(0.22	)

We excluded from the computation of diluted net loss per share stock options, restricted stock units, and ESPP purchase rights to purchase 6,959 shares of common stock for the three months ended April 30, 2011 compared to 16,938 for the three months ended April 30, 2010. The stock options, restricted stock units, and ESPP purchase rights were anti-dilutive either because we incurred a net loss for the period or the stock options were determined to be anti-dilutive as a result of applying the treasury stock method.

The effect of the conversion of the Floating Rate Convertible Subordinated Debentures (Floating Rate Debentures) due 2023 (retired during fiscal 2011), the 6.25% Debentures (retired during the three months ended April 30, 2011), and the 4.00% Debentures was anti-dilutive and therefore excluded from the computation of diluted net income (loss) per share. We assume that the 6.25% Debentures and the 4.00% Debentures will be settled in common stock for purposes of calculating the dilutive effect of the 6.25% Debentures and the 4.00% Debentures.

The conversion features of the 4.00% Debentures, which allow for settlement in cash or a combination of cash and common stock, are further described in Note 8. “Notes Payable.”

Fair Value Measurement

3 Months Ended

Apr. 30, 2011

Fair Value Measurement

(3) Fair Value Measurement—We measure financial instruments at fair value on a quarterly basis. The Financial Accounting Standards Board established a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources. Unobservable inputs reflect our market assumptions. The fair value hierarchy consists of the following three levels:

• Level 1—Quoted prices for identical instruments in active markets;

• Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations whose significant inputs are observable; and

• Level 3—One or more significant inputs to the valuation model are unobservable.

The following table presents information about financial assets and liabilities required to be carried at fair value on a recurring basis as of April 30, 2011:

	Fair Value			Level 1		Level 2		Level 3
Foreign currency exchange contracts	$	1,851		$	—	$	1,851	$	—
Contingent consideration		(6,475	)		—		—		(6,475	)
Total	$	(4,624	)	$	—	$	1,851	$	(6,475	)

The following table presents information about financial assets and liabilities required to be carried at fair value on a recurring basis as of January 31, 2011:

	Fair Value			Level 1		Level 2		Level 3
Foreign currency exchange contracts	$	826		$	—	$	826	$	—
Contingent consideration		(5,342	)		—		—		(5,342	)
Total	$	(4,516	)	$	—	$	826	$	(5,342	)

In connection with certain acquisitions, payment of a portion of the purchase price is contingent upon the acquired business’ achievement of certain revenue goals. We have estimated the fair value of this contingent consideration as the present value of the expected contingent payments over the term of the arrangements and have included $795 of the balance in accrued liabilities and the remaining $5,680 in other long-term liabilities on our condensed consolidated balance sheet.

The following table summarizes Level 3 activity:

Balance as of January 31, 2011	$	5,342
Additions		1,090
Payments		(8	)
Interest accretion		51
Balance as of April 30, 2011	$	6,475

The following table summarizes the fair value and carrying value of notes payable:

As of	April 30, 2011		January 31, 2011
Fair value of notes payable	$	263,484	$	222,591
Carrying value of notes payable	$	210,787	$	209,348

We based the fair value of notes payable on the quoted market price or rates available to us for instruments with similar terms and maturities. Of the total carrying value of notes payable, $2,000 as of January 31, 2011 was classified as current on our condensed consolidated balance sheets. The carrying amount of short-term borrowings of $9,055 as of April 30, 2011 and $15,544 as of January 31, 2011 approximates fair value because of the short-term nature of the instruments.

Commitments and Contingencies

(9) Commitments and Contingencies

Leases

We lease a majority of our field sales offices and research and development facilities under non-cancelable operating leases. In addition, we lease certain equipment used in our research and development activities. This equipment is generally leased on a month-to-month basis after meeting a six-month lease minimum. There have been no significant changes to the future minimum lease payments due under non-cancelable operating leases disclosed in our Annual Report on Form 10-K for the fiscal year ended January 31, 2011.

Indemnifications

Our license and services agreements generally include a limited indemnification provision for claims from third parties relating to our intellectual property. The indemnification is generally limited to the amount paid by the customer or a set cap. As of April 30, 2011, we were not aware of any material liabilities arising from these indemnification obligations.

Legal Proceedings

From time to time we are involved in various disputes and litigation matters that arise in the ordinary course of business. These include disputes and lawsuits relating to intellectual property rights, contracts, distributorships, and employee relations matters. Periodically, we review the status of various disputes and litigation matters and assess our potential exposure. When we consider the potential loss from any dispute or legal matter probable and the amount or the range of loss can be estimated, we will accrue a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, we base accruals on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation matters and may revise estimates. We believe that the outcome of current litigation, individually and in the aggregate, will not have a material effect on our results of operations.

Special Charges

(14) Special Charges—The following is a summary of the components of the special charges:

Three months ended April 30,	2011		2010
Employee severance and related costs	$	1,147	$	1,589
Excess leased facility costs		252		474
Other costs		3,148		1,205
Total special charges	$	4,547	$	3,268

Special charges primarily consist of costs incurred for employee terminations due to a reduction of personnel resources driven by modifications of business strategy or business emphasis. Special charges may also include expenses incurred related to acquisitions, excess facility costs, and asset related charges.

Employee severance and related costs of $1,147 for the three months ended April 30, 2011 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Approximately 27% of these costs were paid during the three months ended April 30, 2011. We expect to pay the remainder during the fiscal year ending January 31, 2012. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $252 for the three months ended April 30, 2011 were primarily due to the abandonment of leased facilities.

Other special charges for the three months ended April 30, 2011 included costs of $3,102 related to consulting fees associated with our proxy contest. Also included in other special charges for the three months ended April 30, 2011 was $46 representing legal and other costs related to acquisitions.

Employee severance and related costs of $1,589 for the three months ended April 30, 2010 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Substantially all of these costs were paid during the fiscal year ending January 31, 2011. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $474 for the three months ended April 30, 2010 were primarily due to the abandonment of leased facilities and changes in the estimate of sublease income for previously abandoned leased facilities.

Other special charges for the three months ended April 30, 2010 included costs of $1,175 related to advisory fees and other costs of $30.

Accrued special charges are included in accrued liabilities and other long-term liabilities in the condensed consolidated Balance Sheets. The following table shows changes in accrued special charges during the three months ended April 30, 2011:

	Accrued special charges as of January 31, 2011		Charges during the three months ended April 30, 2011		Payments during the three months ended April 30, 2011			Accrued special charges as of April 30, 2011 (1)

Employee Stock and Savings Plans

(10) Employee Stock and Savings Plans

Stock Options Plans and Stock Plans

On July 1, 2010, our shareholders approved the 2010 Omnibus Incentive Plan (Incentive Plan) which replaced our prior 1982 Stock Option Plan, Nonqualified Stock Option Plan, 1986 Stock Plan, and 1987 Non-Employee Directors’ Stock Plan. The Incentive Plan is administered by the Compensation Committee of our Board of Directors and permits accelerated vesting of outstanding options, restricted stock units, restricted stock awards, and other equity incentives upon the occurrence of certain changes in control of our company. The implementation of the Incentive Plan did not modify the terms of any awards granted under prior plans.

Stock options under the Incentive Plan are generally expected to vest over four years, have an expiration date of ten years from the date of grant, and an exercise price not less than the fair market value of the shares on the date of grant.

As of April 30, 2011, a total of 8,924 shares of common stock were available for future grant under the above Incentive Plan.

We assumed the stock plans of Valor Computerized Systems, Ltd. (Valor) on March 18, 2010. Under the terms of our merger agreement with Valor, options outstanding under these plans were converted to options to purchase shares of our common stock. Options issued under these plans vest over four years from the original grant date and have an expiration date of ten years from the original grant date. The exercise price of each converted option is equal to the product of the original exercise price and the original number of options granted divided by the number of converted options received. These stock plans have been suspended and no future awards will be granted under these plans. Options for a total of 2,160 shares of our common stock have been authorized and issued under the Valor plans.

On December 14, 2009, our shareholders approved the exchange of certain options for restricted stock units. Eligible for the exchange were options held by non-executive employees with an exercise price equal to or greater than $11.00 which were granted prior to January 7, 2009 and expire after August 15, 2010. The offer expired February 5, 2010. Effective February 8, 2010 a total of 6,945 options were exchanged for 557 restricted stock units. Total incremental cost of $491 resulted from this exchange. The incremental cost will be amortized over two years.

Stock options outstanding, the weighted average exercise price, and transactions involving the stock option plans are summarized as follows:

	Options Outstanding			Weighted Average Exercise Price
Balance as of January 31, 2011		11,867		$	9.94

Nonvested as of April 30, 2011		1,983		$	10.22

Employee Stock Purchase Plans

We have an employee stock purchase plan (ESPP) for U.S. employees and an ESPP for certain foreign subsidiary employees. The ESPPs provide for six month offerings commencing on January 1 and July 1 of each year with purchases on June 30 and December 31 of each year. Each eligible employee may purchase up to six thousand shares of stock on each purchase date at prices no less than 85% of the lesser of the fair market value of the shares on the offering date or on the purchase date. As of April 30, 2011, 3,934 shares remain available for future purchase under the ESPPs.

Stock-Based Compensation Expense

We estimate the fair value of stock options and purchase rights under our ESPPs using a Black-Scholes option-pricing model. The Black-Scholes option-pricing model incorporates several highly subjective assumptions including expected volatility, expected term, and interest rates.

In reaching our determination of expected volatility for options, we include the following elements:

• Historical volatility of our shares of common stock;

• Historical volatility of shares of comparable companies;

• Implied volatility of our traded options; and

• Implied volatility of traded options of comparable companies.

In determining expected volatility for purchase rights under our ESPP, we use the historical volatility of our shares of common stock. The expected term is the six month offering period. We base the expected term of our stock options on historical experience.

The risk-free interest rate for periods within the contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of the grant.

The fair value of restricted stock units is the market value as of the grant date.

The weighted average grant date fair values are summarized as follows:

Three months ended April 30,	2011		2010
Options granted	$	—	$	4.29
Restricted stock units granted	$	15.29	$	7.99

Notes payable, long-term	$	210,787	$	207,348

4.00% Debentures due 2031: In April 2011, we issued $253,000 of 4.00% Convertible Subordinated Debentures (4.00% Debentures) due 2031 in a private placement pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the 4.00% Debentures is payable semi-annually in April and October.

The 4.00% Debentures are convertible, under certain circumstances, into our common stock at a conversion price of $20.538 per share for a total of 12,319 shares as of April 30, 2011. These circumstances include:

• The market price of our common stock exceeding 120% of the conversion price;

• A call for redemption of the 4.00% Debentures;

• Specified distributions to holders of our common stock;

• If a fundamental change, such as a change of control, occurs;

• During the two months prior to, but not on, the maturity date; or

• The market price of the 4.00% Debentures declining to less than 98% of the value of the common stock into which the 4.00% Debentures are convertible.

Upon conversion of any 4.00% Debentures, a holder will receive:

(i) Cash up to the principal amount of the 4.00% Debentures that are converted; and

(ii) Cash or shares of common stock, at our election, for the excess, if any, of the value of the converted shares over the principal amount.

If a holder elects to convert their 4.00% Debentures in connection with a fundamental change in the company that occurs prior to April 5, 2016, the holder will also be entitled to receive a make whole premium upon conversion in some circumstances.

We may redeem some or all of the 4.00% Debentures for cash on or after April 5, 2016 at the following redemption prices expressed as a percentage of principal, plus any accrued and unpaid interest:

Period	Redemption Price
Beginning on April 5, 2016 and ending on March 31, 2017		101.143	%
Beginning on April 1, 2017 and ending on March 31, 2018		100.571	%
On April 1, 2018 and thereafter		100.000	%

The holders, at their option, may redeem the 4.00% Debentures in whole or in part for cash on April 1, 2018, April 1, 2021, and April 1, 2026, and in the event of a fundamental change in the company. In each case, our repurchase price will be 100% of the principal amount of the 4.00% Debentures plus any accrued and unpaid interest.

As the 4.00% Debentures contain conversion features that the debt may be settled in cash upon conversion, we separately account for the implied liability and equity components of the 4.00% Debentures. The principal amount, unamortized debt discount, net carrying amount of the liability component, and carrying amount of the equity component of the 4.00% Debentures are as follows:

As of	April 30, 2011
Principal amount	$	253,000
Unamortized debt discount		(43,526	)
Net carrying amount of the liability component	$	209,474
Equity component	$	43,930

The unamortized debt discount will be amortized to interest expense using the effective interest method through March 2018.

We recognized the following amounts in interest expense in the condensed consolidated statement of operations related to the 4.00% debentures:

Three months ended April 30,	2011
Interest expense at the contractual interest rate	$	759
Amortization of debt discount	$	404

The effective interest rate on the 4.00% Debentures was 7.25% for the three months ended April 30, 2011.

6.25% Debentures due 2026: In March 2006, we issued $200,000 of 6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026 in a private offering pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the 6.25% Debentures was payable semi-annually in March and September.

The principal amount, unamortized debt discount, net carrying amount of the liability component, and carrying amount of the equity component of the 6.25% Debentures, issued 2006, were as follows:

As of	April 30, 2011		January 31, 2011
Principal amount	$	—	$	165,000
Unamortized debt discount		—		(7,157	)
Net carrying amount of the liability component	$	—	$	157,843
Equity component	$	—	$	21,766

We recognized the following amounts in interest expense in the condensed consolidated statements of operations related to the 6.25% Debentures, issued 2006:

Three months ended April 30,	2011		2010
Interest expense at the contractual interest rate	$	2,900	$	2,578
Amortization of debt discount	$	793	$	729

The effective interest rate on the 6.25% Debentures, was 8.60% for the three months ended April 30, 2011 and 2010.

The principal amount, unamortized premium, and net carrying amount of the 6.25% Debentures, issued fiscal 2011, were as follows:

As of	April 11, 2011		January 31, 2011
Principal amount	$	—	$	31,509
Unamortized debt premium		—		196
Net carrying amount of the liability component	$	—	$	31,705

No equity component was recorded for the 6.25% Debentures, issued fiscal 2011, as the conversion feature was deemed to be non-beneficial when the debt was issued.

During the three months ended April 30, 2011, we redeemed the remaining $196,509 principal amount of 6.25% Debentures utilizing proceeds received from the issuance of the 4.00% Debentures and cash on hand. In connection with this redemption, we incurred a before tax net loss on the early extinguishment of debt of $11,192, which included a $6,190 write-off of net unamortized debt discount, a $3,518 premium on redemption of the 6.25% Debentures, and a write-off of $1,484 for the unamortized debt issuance costs. This loss is included in interest expense on the condensed consolidated statement of operations. No balance remains outstanding following this redemption.

Term Loan due 2013: In April 2010, we entered into a three-year term loan (Term Loan) for $20,000 to repay borrowings under our revolving credit facility used to purchase office buildings in Fremont, California. Fixed principal of $500 and accrued interest payments were payable quarterly in February, May, August, and November.

During the three months ended April 30, 2011, we repaid the remaining obligation of $18,500 under the Term Loan utilizing proceeds received from the issuance of the 4.00% Debentures. In connection with this repayment, we incurred a before tax net loss on early retirement of debt of $312, representing the write-off of the unamortized debt issuance costs. This loss is included in interest expense on the condensed consolidated statement of operations. The effective interest rate was 4.81% for the three months ended April 30, 2011. No balance remains outstanding following this repayment.

Other Notes Payable: In November 2009, we issued a subordinated note payable as part of a business combination. The note bears interest at a rate of 3.875% and is due in full along with all accrued interest on November 17, 2012.

General

(1) General—The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with United States (U.S.) generally accepted accounting principles (GAAP) and reflect all material normal recurring adjustments. However, certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the condensed consolidated financial statements include adjustments necessary for a fair presentation of the results of the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes included in our Annual Report on Form 10-K for the fiscal year ended January 31, 2011.

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingencies as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from these estimates. Any changes in estimates will be reflected in the financial statements in future periods.

Business Combinations

(4) Business Combinations—For each business we acquire, the excess of the fair value of the consideration transferred over the fair value of the net tangible assets acquired and net tangible liabilities assumed was allocated to various identifiable intangible assets and goodwill. Identifiable intangible assets typically consist of purchased technology and customer-related intangibles, which are amortized to expense over their useful lives. Goodwill, representing the excess of the purchase consideration over the fair value of net tangible and identifiable intangible assets, is not amortized.

During the three months ended April 30, 2011, we acquired one privately-held company, which was not material individually or in the aggregate, for a total consideration of $1,890.

The separate results of operations for the acquisitions during the three months ended April 30, 2011 were not material, individually or in the aggregate, compared to our overall results of operations and accordingly, pro-forma financial statements of the combined entities have been omitted.

Derivative Instruments and Hedging Activities

3 Months Ended

Apr. 30, 2011

Derivative Instruments and Hedging Activities

(5) Derivative Instruments and Hedging Activities—We are exposed to fluctuations in foreign currency exchange rates. To manage the volatility, we aggregate exposures on a consolidated basis to take advantage of natural offsets. The primary exposures are the Japanese yen, where we are in a long position, and the euro and the British pound, where we are in a short position. Most large European revenue contracts are denominated and paid to us in U.S. dollars while our European expenses, including substantial research and development operations, are paid in local currencies causing a short position in the euro and the British pound. In addition, we experience greater inflows than outflows of Japanese yen as almost all Japanese-based customers contract and pay us in Japanese yen. While these exposures are aggregated on a consolidated basis to take advantage of natural offsets, substantial exposures remain.

To partially offset the net exposures in the euro, British pound, and the Japanese yen, we enter into foreign currency exchange contracts of less than one year which are designated as cash flow hedges. Any gain or loss on Japanese yen contracts is classified as product revenue when the hedged transaction occurs while any gain or loss on euro and British pound contracts is classified as operating expense when the hedged transaction occurs.

We formally document all relationships between foreign currency exchange contracts and hedged items as well as our risk management objectives and strategies for undertaking various hedge transactions. All hedges designated as cash flow hedges are linked to forecasted transactions and we assess, both at inception of the hedge and on an ongoing basis, the effectiveness of the foreign currency exchange contracts in offsetting changes in the cash flows of the hedged items. We report the effective portions of the net gains or losses on foreign currency exchange contracts as a component of accumulated other comprehensive income in stockholders’ equity. Accumulated other comprehensive income associated with hedges of forecasted transactions is reclassified to the condensed consolidated statement of operations in the same period the forecasted transaction occurs. We discontinue hedge accounting prospectively when we determine that a foreign currency exchange contract is not highly effective as a hedge. To the extent a forecasted transaction is no longer deemed probable of occurring, we prospectively discontinue hedge accounting treatment and we reclassify deferred amounts to other expense, net in the condensed consolidated statement of operations. We noted no such instance during the three months ended April 30, 2011 or 2010.

The fair values and balance sheet presentation of our derivative instruments as of April 30, 2011 are summarized as follows:

	Location		Asset Derivatives		Liability Derivatives
Derivatives designated as hedging instruments:
Cash flow forwards		Other receivables	$	725	$	(161	)
Derivatives not designated as hedging instruments:
Non-designated forwards		Other receivables		1,911		(624	)
Total derivatives			$	2,636	$	(785	)

The fair values and balance sheet presentation of our derivative instruments as of January 31, 2011 are summarized as follows:

	Location		Asset Derivatives		Liability Derivatives
Derivatives designated as hedging instruments:
Cash flow forwards		Other receivables	$	575	$	(414	)
Derivatives not designated as hedging instruments:
Non-designated forwards		Other receivables		1,125		(460	)
Total derivatives			$	1,700	$	(874	)

During the three months ended April 30, 2011, we entered into 366 new foreign currency forward contracts. We had a total of 37 contracts outstanding with a total gross notional value of $126,716 outstanding as of April 30, 2011. For the three months ended April 30, 2010, we entered into 337 new foreign currency contracts. We had a total of 43 contracts with a total gross notional value of $203,281 outstanding as of April 30, 2010. Notional amounts do not quantify risk or represent our assets or liabilities but are used in the calculation of cash settlements under the contracts.

By using derivative instruments, we subject ourselves to credit risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair value of the derivative instrument. Generally, when the fair value of our derivative contracts is a net asset, the counterparty owes us, thus creating a receivable risk. We minimize counterparty credit risk by entering into derivative transactions with major financial institutions and, therefore, we do not expect material losses as a result of default by our counterparties.

The pre-tax effect of derivative instruments in cash flow hedging relationships on income and other comprehensive income (OCI) for the three months ended April 30, 2011 is as follows:

Derivatives Designated as Hedging Instruments	Gain Recognized in OCI on Derivatives (Effective Portion)		Gain (loss) Reclassified from Accumulated OCI into Income (Effective  Portion)				Gain Recognized in Income on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing)
	Amount		Location	Amount			Location	Amount
Cash flow forwards	$	586	Revenues	$	(449	)	Other expense, net	$	24
			Operating expenses		560
Total	$	586		$	111			$	24

The gain on cash flow forwards of $24 recognized in other expense, net for the three months ended April 30, 2011 is related to the time value exclusion of foreign currency forward contracts from our assessment of hedge effectiveness.

The pre-tax effect of derivative instruments in cash flow hedging relationships on income and OCI for the three months ended April 30, 2010 is as follows:

Derivatives Designated as Hedging Instruments	Loss Recognized in OCI on Derivatives (Effective Portion)			Loss Reclassified from Accumulated OCI into Income (Effective Portion)				Gain Recognized in Income on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing)
	Amount			Location	Amount			Location	Amount
Cash flow forwards	$	(1,250	)	Revenues	$	(131	)	Other expense, net	$	30
				Operating expenses		(1,713	)
Total	$	(1,250	)		$	(1,844	)		$	30

The gain on cash flow forwards of $30 recognized in other expense, net for the three months ended April 30, 2010 was related to the time value exclusion of foreign currency forward contracts from our assessment of hedge effectiveness.

The hedge balance in accumulated other comprehensive income was as follows:

As of	April 30, 2011		January 31, 2011
Accumulated OCI before tax effect	$	545	$	69
Accumulated OCI after tax effect	$	455	$	(2	)

The balance represents a net unrealized gain on foreign currency exchange contracts related to hedges of forecasted revenues and expenses expected to occur within the next twelve months. We will transfer this amount to the condensed consolidated statement of operations upon recognition of the related revenues and recording of the respective expenses. We expect substantially all of the hedge balance in accumulated other comprehensive income to be reclassified to the condensed consolidated statement of operations within the next twelve months.

We enter into foreign currency exchange contracts to offset the earnings impact relating to the variability in exchange rates on certain short-term monetary assets and liabilities denominated in non-functional currencies. We do not designate these foreign currency contracts as hedges. The effect of derivative instruments not designated as hedging instruments on income is as follows:

Derivatives Not Designated as Hedging Instruments	Gain Recognized in Income on Derivatives
	Location	Amount as of April 30, 2011		Amount as of April 30, 2010
Non-designated forwards	Other expense, net	$	3,281	$	1,423

Term Receivables and Trade Accounts Receivable

3 Months Ended

Apr. 30, 2011

Term Receivables and Trade Accounts Receivable

(6) Term Receivables and Trade Accounts Receivable—We have long-term installment receivables that are attributable to multi-year, multi-element term license sales agreements. We include balances under term agreements that are due within one year in trade accounts receivable, net and balances that are due more than one year from the balance sheet date in term receivables, long-term. We discount the total product portion of the agreements to reflect the interest component of the transaction. We amortize the interest component of the transaction, using the effective interest method, to system and software revenues over the period in which payments are made and balances are outstanding. We determine the discount rate at the outset of the arrangement based upon the current credit rating of the customer. We reset the discount rate periodically considering changes in prevailing interest rates but do not adjust previously discounted balances.

Term receivable and trade accounts receivable balances were as follows:

As of	April 30, 2011		January 31, 2011
Trade accounts receivable	$	139,028	$	153,733
Term receivables, short-term	$	182,012	$	193,342
Term receivables, long-term	$	179,014	$	167,425

Trade accounts receivable include billed amounts whereas term receivables, short-term is comprised of unbilled amounts. Term receivables, short term represent the portion of long-term installment agreements that are due within one year. Billings for term agreements typically occur 30 days prior to the contractual due date, in accordance with individual contract installment terms. Term receivables, long-term represent unbilled amounts which are scheduled to be collected beyond one year.

We perform a credit risk assessment of all customers using the S&P credit rating as our primary credit-quality indicator. The S&P credit ratings are based on the most recent S&P score available. For customers that do not have an S&P credit rating, we base our credit risk assessment on an internal credit assessment which is based on selected short-term financial ratios. Our internal credit assessment is based upon results provided in the customers’ most recent financial statements.

The credit risk assessment for our long-term receivables was as follows:

As of	April 30, 2011		January 31, 2011
S&P credit rating:
AAA+ through BBB-	$	106,906	$	84,685
BB+ and lower		11,594		19,473
		118,500		104,158
Internal credit assessment		60,514		63,267
Total long-term term receivables	$	179,014	$	167,425

We maintain allowances for doubtful accounts on trade accounts receivable and term receivables, long-term for estimated losses resulting from the inability of our customers to make required payments. We regularly evaluate the collectibility of our trade accounts receivable based on a combination of factors. When we become aware of a specific customer’s inability to meet its financial obligations, such as in the case of bankruptcy or deterioration in the customer’s operating results, financial position, or credit rating, we record a specific reserve for bad debt to reduce the related receivable to the amount believed to be collectible. We also record unspecified reserves for bad debt for all other customers based on a variety of factors including length of time the receivables are past due, the financial health of the customers, the current business environment, and historical experience. Current economic conditions we have considered include forecasted spending in the semiconductor industry, consumer spending for electronics, integrated circuit research and development spending, and volatility in gross domestic product. If these factors change or circumstances related to specific customers change, we adjust the estimates of the recoverability of receivables resulting in either additional selling expense or a reduction in selling expense in the period such determination is made.

The following shows the change in allowance for doubtful accounts for the three months ended April 30, 2011:

	Beginning balance as of January 31, 2011		Charged (credited) to expense			Deductions(1)		Ending balance as of April 30, 2011
Allowance for doubtful accounts	$	3,941	$	(182	)	$	21	$	3,780

⁽¹⁾  Specific account write-offs and foreign exchange.

We enter into agreements to sell qualifying accounts receivable from time to time to certain financing institutions on a non-recourse basis. We received net proceeds from the sale of receivables of $11,403 for the three months ended April 30, 2011 compared to $14,909 for the three months ended April 30, 2010.

Income Taxes

Income Taxes

(16) Income Taxes—The provision for income taxes was comprised of the following:

Three months ended April 30,	2011		2010
Income tax expense	$	611	$	2,563

Generally, the provision for income taxes is the result of the mix of profits and losses earned by us and our subsidiaries in tax jurisdictions with a broad range of income tax rates, withholding taxes (primarily in certain foreign jurisdictions), changes in tax reserves, and the application of valuation allowances on deferred tax assets. Accounting guidance requires that on a quarterly basis we evaluate our provision for income tax expense (benefit) of U.S. and non-U.S. jurisdictions based on our projected results of operations for the full year and record an adjustment in the current quarter.

Three months ended April 30,	2011			2010
Effective Tax Rate		(35%)			(13%)
Period specific items expense (benefit)	$	(1,334	)	$	353

Without period specific items, our effective tax rate is (112%) for the three months ended April 30, 2011. Under our forecast of income for the year, we project a 12% effective tax rate with the inclusion of period specific items. Our effective tax rate differs from tax computed at the U.S. federal statutory rate of 35% primarily due to:

• The benefit of lower tax rates on earnings of foreign subsidiaries;

• Reduction in reserves for uncertain foreign tax positions; and

• The application of tax incentives for research and development in certain foreign jurisdictions.

These differences are partially offset by:

• U.S. losses for which no tax benefit has been recognized;

• Non-deductible employee stock purchase plan compensation expense; and

• Withholding taxes in certain foreign jurisdictions.

Actual results may differ significantly from our current projections. Further, on a quarterly basis, our effective tax rate could fluctuate considerably and could be adversely affected to the extent earnings are higher or lower than anticipated in countries where we have corresponding higher or lower statutory rates.

As of April 30, 2011, we had a liability of $42,422 for income taxes associated with uncertain income tax positions. All of these tax positions are classified as long-term liabilities in our condensed consolidated balance sheet. We are not able to reasonably estimate the timing of any cash payments required to settle these liabilities; however, we generally do not anticipate the settlement of the liabilities will require payment of cash within the next twelve months. We do not believe that the ultimate settlement of these liabilities will materially affect our liquidity. Further, certain liabilities may result in the reduction of deferred tax assets rather than settlement in cash.

Summary of Significant Accounting Policies

(2) Summary of Significant Accounting Policies

Principles of Consolidation

The condensed consolidated financial statements include our financial statements and those of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

We do not have off-balance sheet arrangements, financings, or other similar relationships with unconsolidated entities or other persons, also known as special purpose entities. In the ordinary course of business, we lease certain equipment and certain real properties, primarily field sales offices, research and development facilities, and equipment, as described in Note 9. “Commitments and Contingencies.”

Revenue Recognition

We report revenue in two categories based on how the revenue is generated: (i) system and software and (ii) service and support.

System and software revenues – We derive system and software revenues from the sale of licenses of software products, emulation hardware systems, and finance fee revenues from our long-term installment receivables resulting from product sales. We primarily license our products using two different license types:

1. Term licenses – We use this license type primarily for software sales. This license type provides the customer with the right to use a fixed list of software products for a specified time period, typically three years, with payments spread over the license term, and does not provide the customer with the right to use the products after the end of the term. Term license arrangements may allow the customer to share products between multiple locations and remix product usage from the fixed list of products at regular intervals during the license term. We generally recognize product revenue from term license arrangements upon product delivery and start of the license term. In a term license agreement where we provide the customer with rights to unspecified or unreleased future products, we recognize revenue ratably over the license term.

2. Perpetual licenses – We use this license type for software and emulation hardware system sales. This license type provides the customer with the right to use the product in perpetuity and typically does not provide for extended payment terms. We generally recognize product revenue from perpetual license arrangements upon product delivery assuming all other criteria for revenue recognition have been met.

We include finance fee revenues from the accretion on the discount of long-term installment receivables in system and software revenues.

Service and support revenues – We derive service and support revenues from software and hardware post-contract maintenance or support services and professional services, which include consulting, training, and other services. We recognize revenue ratably over the support services term. We record professional service revenue as the services are provided to the customer.

We determine whether product revenue recognition is appropriate based upon the evaluation of whether the following four criteria have been met:

1. Persuasive evidence of an arrangement exists – Generally, we use either a customer signed contract or qualified customer purchase order as evidence of an arrangement for both term and perpetual licenses. For professional service engagements, we generally use a signed professional services agreement and a statement of work to evidence an arrangement. Sales through our distributors are evidenced by an agreement governing the relationship, together with binding purchase orders from the distributor on a transaction-by-transaction basis.

2. Delivery has occurred – We generally deliver software and the corresponding access keys to customers electronically. Electronic delivery occurs when we provide the customer access to the software. We may also deliver the software on a compact disc. With respect to emulation hardware systems, we transfer title to the customer upon shipment. Our software license and emulation hardware system agreements generally do not contain conditions for acceptance.

3. Fee is fixed or determinable – We assess whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. We have established a history of collecting under the original contract with installment terms without providing concessions on payments, products, or services. Additionally, for installment contracts, we determine that the fee is fixed or determinable if the arrangement has a payment schedule that is within the term of the licenses and the payments are collected in equal or nearly equal installments, when evaluated on a cumulative basis. If the fee is not deemed to be fixed or determinable, we recognize revenue as payments become due and payable.

Significant judgment is involved in assessing whether a fee is fixed or determinable. We must also make these judgments when assessing whether a contract amendment to a term arrangement (primarily in the context of a license extension or renewal) constitutes a concession. Our experience has been that we are able to determine whether a fee is fixed or determinable for term licenses. If we no longer were to have a history of collecting under the original contract without providing concessions on term licenses, revenue from term licenses would be required to be recognized when payments under the installment contract become due and payable. Such a change could have a material impact on our results of operations.

4. Collectibility is probable – To recognize revenue, we must judge collectibility of the arrangement fees on a customer-by-customer basis pursuant to our credit review process. We typically sell to customers with whom there is a history of successful collection. We evaluate the financial position and a customer’s ability to pay whenever an existing customer purchases new products, renews an existing arrangement, or requests an increase in credit terms. For certain industries for which our products are not considered core to the industry or the industry is generally considered troubled, we impose higher credit standards. If we determine that collectibility is not probable based upon our credit review process or the customer’s payment history, we recognize revenue as payments are received.

Multiple element arrangements involving software licenses – For multiple element arrangements involving software and other software-related deliverables, vendor-specific objective evidence of fair value (VSOE) must exist to allocate the total fee among all delivered and non-essential undelivered elements of the arrangement. If undelivered elements of the arrangement are essential to the functionality of the product, we defer revenue until the essential elements are delivered. If VSOE does not exist for one or more non-essential undelivered elements, we defer revenue until such evidence exists for the undelivered elements, or until all elements are delivered, whichever is earlier. If VSOE of all non-essential undelivered elements exist but VSOE does not exist for one or more delivered elements, we recognize revenue using the residual method. Under the residual method, we defer revenue related to the undelivered elements based upon VSOE and we recognize the remaining portion of the arrangement fee as revenue for the delivered elements, assuming all other criteria for revenue recognition are met. If we can no longer establish VSOE for non-essential undelivered elements of multiple element arrangements, we defer revenue until all elements are delivered or VSOE was established for the undelivered elements, whichever is earlier.

We base our VSOE for certain product elements of an arrangement upon the pricing in comparable transactions when the element is sold separately. We primarily base our VSOE for term and perpetual support services upon customer renewal history where the services are sold separately. We also base VSOE for professional services and installation services for emulation hardware systems upon the price charged when the services are sold separately.

Multiple element arrangements involving hardware – For multiple element arrangements involving our emulation hardware systems, we allocate revenue to each element based on the relative selling price of each deliverable. In order to meet the separation criteria to allocate revenue to each element we must determine the standalone selling price of each element using a hierarchy of evidence. The authoritative guidance requires that, in the absence of VSOE or third-party evidence (TPE), a company must develop an estimated selling price (ESP). ESP is defined as the price at which the vendor would transact if the deliverable was sold by the vendor regularly on a standalone basis. A company should consider market conditions as well as entity-specific factors when estimating a selling price.

When VSOE or TPE does not exist, we base our ESP for certain elements in arrangements based on either costs incurred to manufacture a product plus a reasonable profit margin or standalone sales to similar customers. In determining profit margins, we consider current market conditions, pricing strategies related to the class of customer, and the level of penetration we have with the customer. In other cases, we may have limited sales on a standalone basis to the same or similar customers and/or guaranteed pricing on future purchases of the same item. If we are unable to demonstrate value on a standalone basis of an element, we could be required to combine elements which could impact the timing of revenue recognition if not delivered together.

Reclassification

Certain immaterial reclassifications have been made in the condensed consolidated balance sheet to correct the presentation as of January 31, 2011. Specifically, we made a reclassification to other assets of $5,481 which was incorrectly classified as other receivables.

Incentive Stock Rights

(11) Incentive Stock Rights—Our Board of Directors has the authority to issue incentive stock in one or more series and to determine the relative rights and preferences of the incentive stock. On June 24, 2010, we adopted an Incentive Stock Purchase Rights Plan and declared a dividend distribution of one Right for each outstanding share of common stock, payable to holders of record on July 6, 2010. As long as the Rights are attached to our common stock, we will issue one Right with each new share of common stock so that all such shares will have attached Rights. Under certain conditions, each Right may be exercised to purchase 1/10,000 of a share of Series B Junior Participating Incentive Stock (Incentive Stock) at a purchase price of fifty dollars, subject to adjustment. The Rights are not presently exercisable and will only become exercisable if a person or group acquires or commences a tender offer to acquire 15% or more of our common stock. If a person or group acquires 15% or more of the common stock, each Right will be adjusted to entitle its holder to receive, upon exercise, common stock (or, in certain circumstances, other assets of ours) having a value equal to two times the exercise price of the Right or each Right will be adjusted to entitle its holder to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the Right, depending on the circumstances. The Rights expire on December 31, 2011 and may be redeemed by us for $0.001 per Right. The Rights do not have voting or dividend rights and have no dilutive effect on our earnings.
