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, 2012 .

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 and majority-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 real properties, primarily field sales offices, research and development facilities, and equipment as described in Note 7 . “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 of the discount on 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 revenues ratably over the support services term. We record professional service revenues as the services are provided to the customer.

Table Of Contents

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 is established for the undelivered elements, whichever is earlier.

We base our VSOE for certain 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

Table Of Contents

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 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.

Noncontrolling Interest with Redemption Feature

As of October 31, 2012 , our balance sheet includes a noncontrolling interest resulting from a business combination in which we acquired majority ownership in a privately-held company. In conjunction with this business combination, we also entered into an agreement which allows the other owners of the company to require us to purchase their noncontrolling interest at a future date for a price based on a formula defined in the agreement. The noncontrolling interest adjusted for this redemption feature is presented on the condensed consolidated balance sheet under the caption “Noncontrolling interest with redemption feature.” Because the redemption of the noncontrolling interest is outside of our control, we have presented this interest outside of stockholders’ equity.

The noncontrolling interest with redemption feature is recognized at the greater of:


i.	The calculated redemption value as of the balance sheet date, as if it were redeemable; or


ii.	The initial noncontrolling interest value adjusted for the noncontrolling interest holders' share of:


a.	cumulative net income (loss); and


b.	other changes in accumulated other comprehensive income.

Adjustments based on the calculated redemption value are recorded directly to retained earnings. To the extent this adjustment is considered to be material, we would adjust the numerator in our earnings per share calculation in the current period.

The results of the majority-owned subsidiary are presented in our consolidated results with an adjustment reflected on the face of our statement of income and the face of our statement of comprehensive income for the noncontrolling investors’ interest in the results of the subsidiary.

Recent Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2011-11, “Balance Sheet (Topic 210) Disclosures about Offsetting Assets and Liabilities.” ASU 2011-11 requires entities to disclose both gross information and net information about both instruments and transactions subject to a master netting arrangement. ASU 2011-11 is intended to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards (IFRS). ASU 2011-11 is effective retrospectively for annual reporting periods beginning on or after January 31, 2013 and interim periods within those annual periods. We do not anticipate a material impact on our financial statements upon adoption, other than additional disclosures.

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which amends Accounting Standards Codification 350, “Intangibles — Goodwill and Other.” The amended guidance reduces complexity and cost by allowing an entity to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. This initial assessment serves as a basis for determining if performing the quantitative impairment test is necessary. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. The implementation of this amended accounting guidance is not expected to have a material impact on our consolidated financial statements.

(3) Fair Value Measurement— The following table presents information about financial assets and liabilities measured at fair value on a recurring basis as of October 31, 2012 :



	Fair Value			Level 1		Level 2			Level 3
Foreign currency exchange contracts	$	(203	)	$	—	$	(203	)	$	—
Contingent consideration	(6,217		)	—		—			(6,217		)
Total	$	(6,420	)	$	—	$	(203	)	$	(6,217	)

The following table presents information about financial assets and liabilities measured at fair value on a recurring basis as of January 31, 2012 :



	Fair Value			Level 1		Level 2		Level 3
Foreign currency exchange contracts	$	882		$	—	$	882	$	—
Contingent consideration	(6,120		)	—		—		(6,120		)
Total	$	(5,238	)	$	—	$	882	$	(6,120	)

The FASB's authoritative guidance for the hierarchy of valuation techniques is 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.

We use an income approach to determine the fair value of our foreign currency exchange contracts. The net gains or losses for foreign currency exchange contracts designated as cash flow hedges, which are linked to a specific transaction, are reported in accumulated other comprehensive income in stockholders' equity until the forecasted transaction occurs or the hedge is no longer effective. Once the forecasted transaction occurs or the hedge is no longer effective, we reclassify the gains or losses attributable to the foreign currency exchange contracts to our consolidated statement of income. Foreign currency exchange contracts are recorded at fair value utilizing observable market inputs at measurement date and standard valuation techniques.

We recognize changes in fair value for foreign currency exchange contracts entered into to offset the variability in exchange rates on certain short-term monetary assets and liabilities in other income (expense), net, in our consolidated statement of income. The fair value of foreign currency exchange contracts is included in other receivables, if the balance is an asset, or accrued liabilities, if the balance is a liability, on our consolidated balance sheet.

In connection with certain acquisitions, payment of a portion of the purchase price is contingent typically upon the acquired business’ achievement of certain revenue goals. As of October 31, 2012 , of the total recorded balance, $1,896 was included in accrued liabilities and $4,321 was included in other long-term liabilities on our condensed consolidated balance sheet. As of January 31, 2012 , of the total recorded balance, $510 was included in accrued liabilities and $5,610 was included in other long-term liabilities on our condensed consolidated balance sheet.

We have estimated the fair value of our contingent consideration as the present value of the expected payments over the term of the arrangements. The fair value measurement of our contingent consideration as of October 31, 2012 encompasses the following significant unobservable inputs:

Table Of Contents



Unobservable Inputs	Range
Total estimated contingent consideration	$0		-	$8,476
Discount rate	14	%	-	16%
Timing of cash flows (in years)	0		-	5

Changes in the fair value of our contingent consideration are primarily driven by changes in the estimated amount and timing of payments, resulting from changes in the forecasted revenues of the acquired businesses. Significant changes in any of the inputs in isolation could result in a fluctuation in the fair value measurement of contingent consideration. Changes in fair value are recognized in operating income in the period in which the change is identified. During the nine months ended October 31, 2012 , we recorded decreases in contingent consideration resulting in a net gain of $540 to special charges in our condensed consolidated statement of income. The adjustments to the liability were due to changes in the timing and amounts of the expected payments.

The following table summarizes contingent consideration activity:




Balance as of January 31, 2012	$	6,120
New contingent consideration	950
Payments	(478		)
Adjustments	(540		)
Interest accretion	165
Balance as of October 31, 2012	$	6,217

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



As of	October 31, 2012		January 31, 2012
Fair value of notes payable	$	288,789	$	259,821
Carrying value of notes payable	$	218,560	$	214,573

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 (Level 2). Of the total carrying value of notes payable, $1,381 as of October 31, 2012 and $1,349 as of January 31, 2012 was classified as current on our condensed consolidated balance sheets.

The carrying amounts of cash equivalents, trade accounts receivable, net, term receivables, short-term borrowings, accounts payable, and accrued liabilities approximate fair value because of the short-term nature of these instruments or because amounts have been appropriately discounted.

(4) 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	October 31, 2012		January 31, 2012
Trade accounts receivable	$	171,916	$	133,494
Term receivables, short-term	$	232,867	$	221,430
Term receivables, long-term	$	207,639	$	220,355

Table Of Contents

Trade accounts receivable include billed amounts whereas term receivables, short-term are 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 Standard & Poor’s (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. We determine whether or not to extend credit to these customers based on the results of our internal credit assessment, thus, mitigating our risk of loss.

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



As of	October 31, 2012		January 31, 2012
S&P credit rating:
AAA+ through BBB-	$	107,918	$	130,545
BB+ and lower	37,213		15,161
	145,131		145,706
Internal credit assessment	62,508		74,649
Total long-term term receivables	$	207,639	$	220,355

We maintain allowances for doubtful accounts on trade accounts receivable and term receivables 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 consider 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:



Allowance for doubtful accounts	Beginning balance		Charged to expense		Deductions ⁽¹⁾			Ending balance
Nine months ended October 31, 2012	$	4,432	$	285	$	(146	)	$	4,571

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



As of	October 31, 2012		January 31, 2012
Collections of previously sold accounts receivable	$	1,525	$	9,373
Other borrowings	1,311		5,244
Short-term borrowings	$	2,836	$	14,617

Table Of Contents

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 . As stated in the 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 October 31,				Nine months ended October 31,
	2012		2011		2012		2011
Commitment fees	$	128	$	128	$	382	$	257

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;


•	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 P4Y 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 October 31, 2012 . 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 on the revolving credit facility. As a result, our lenders could terminate the facility and demand immediate repayment of all outstanding loans under the revolving credit facility.

We had no borrowings against the revolving credit facility during the nine months ended October 31, 2012 and 2011 .

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 capital leases and other borrowings. Interest rates are generally based on the applicable country’s prime lending rate.

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

Table Of Contents



As of	October 31, 2012		January 31, 2012
4.00% Debentures due 2031	$	217,179	$	213,224
Other	1,381		1,349
Notes payable	$	218,560	$	214,573

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 October 31, 2012 . 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.

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	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 a conversion feature that allows the debt to 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	October 31, 2012			January 31, 2012
Principal amount	$	253,000		$	253,000
Unamortized debt discount	(35,821		)	(39,776		)
Net carrying amount of the liability component	$	217,179		$	213,224
Equity component	$	43,930		$	43,930

Table Of Contents

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 income related to the 4.00% Debentures:



	Three months ended October 31,				Nine months ended October 31,
	2012		2011		2012		2011
Interest expense at the contractual interest rate	$	2,530	$	2,530	$	7,590	$	5,819
Amortization of debt discount	$	1,342	$	1,250	$	3,955	$	2,882

The effective interest rate on the 4.00% Debentures was 7.25% for the nine months ended October 31, 2012 .

6.25% Debentures due 2026 : During the nine months ended October 31, 2011 , we redeemed the remaining $196,509 principal amount of the 6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026 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 income. No balance remained outstanding following this redemption.

We recognized the following amounts in interest expense in the condensed consolidated statements of income related to the 6.25% Debentures:



	Three months ended October 31,				Nine months ended October 31,
	2012		2011		2012		2011
Interest expense at the contractual interest rate	$	—	$	—	$	—	$	2,900
Amortization of debt discount	$	—	$	—	$	—	$	793

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. During the nine months ended October 31, 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 the 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 income. No balance remained 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 .


(7)	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, 2012 .

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, a multiple of the amount paid by the customer, or a set cap. As of October 31, 2012 , we were not aware of any material liabilities arising from these indemnification obligations.

Table Of Contents

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. To the extent there is a reasonable possibility (within the meaning of ASC 450 Contingencies ) that losses could exceed amounts already accrued, if any, and the additional loss or range of loss is able to be estimated, we would disclose the additional loss or range of 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.

In some instances, we are unable to reasonably estimate any potential loss or range of loss. The nature and progression of litigation can make it difficult to predict the impact a particular lawsuit will have. There are many reasons that we cannot make these assessments, including, among others, one or more of the following: the early stages of a proceeding; damages sought that are unspecific, unsupportable, unexplained or uncertain; discovery not having been started or incomplete; the complexity of the facts that are in dispute; the difficulty of assessing novel claims; the parties not having engaged in any meaningful settlement discussions; the possibility that other parties may share in any ultimate liability; and/or the often slow pace of litigation.


(8)	Employee Stock and Savings Plans

Stock Options Plans and Stock Plans

Our 2010 Omnibus Incentive Plan (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. Stock options and restricted stock units under the Incentive Plan are generally expected to vest over four years. Stock options have an expiration date of ten years from the date of grant and an exercise price no less than the fair market value of the shares on the date of grant.

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 (but no more than an annual offering date total fair market value of $25 ) 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.

Stock-Based Compensation Expense

The following table summarizes stock compensation expense recognized:



	Three months ended October 31,				Nine months ended October 31,
	2012		2011		2012		2011
Cost of revenues	$	393	$	249	$	1,080	$	753
Operating expenses:
Research and development	2,272		2,005		6,604		6,119
Marketing and selling	1,644		1,365		4,818		4,393
General and administration	1,400		1,495		4,660		5,358
Equity plan-related compensation expense	$	5,709	$	5,114	$	17,162	$	16,623

(9) 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 . On December 23, 2011 , our Board of Directors amended the Stock Purchase Rights Plan to, among

Table Of Contents

other things, extend the expiration date of the rights and increase the exercise price of each right. 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 at a purchase price of sixty-five 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 June 30, 2013 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.

(10) Net Income Per Share —We compute basic net income per share using the weighted average number of common shares outstanding during the period. We compute diluted net income 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 vesting of restricted stock units, common shares issuable upon exercise of stock options, and purchase rights from ESPPs 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 income per share:



	Three months ended October 31,				Nine months ended October 31,
	2012		2011		2012		2011
Net income attributable to Mentor Graphics shareholders	$	30,641	$	24,071	$	76,990	$	26,052
Weighted average common shares used to calculate basic net income per share	111,575		109,501		110,454		110,423
Employee stock options, restricted stock units, and employee stock purchase plan	3,146		2,062		3,130		2,758
Weighted average common and potential common shares used to calculate diluted net income per share	114,721		111,563		113,584		113,181
Basic net income per share attributable to Mentor Graphics shareholders	$	0.27	$	0.22	$	0.70	$	0.24
Diluted net income per share attributable to Mentor Graphics shareholders	$	0.27	$	0.22	$	0.68	$	0.23

We excluded from the computation of diluted net income per share stock options, restricted stock units, and ESPP purchase rights to purchase 1,205 shares of common stock for the three months ended October 31, 2012 and 2,626 shares of common stock for the nine months ended October 31, 2012 compared to 7,704 for the three months ended October 31, 2011 and 4,613 for the nine months ended October 31, 2011 . These stock options, restricted stock units, and ESPP purchase rights were determined to be anti-dilutive as a result of applying the treasury stock method.

We assume that the 4.00% Debentures will be settled in common stock for purposes of calculating the dilutive effect of the 4.00% Debentures. The effect of the assumed conversion of the 4.00% Debentures was anti-dilutive and therefore excluded from the computation of diluted net income per share.

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 6 . “ Notes Payable .”


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



	Three months ended October 31,					Nine months ended October 31,
	2012		2011			2012		2011
Employee severance and related costs	$	612	$	1,227		$	2,629	$	3,581
Other costs	534		(63		)	1,171		3,807
Total special charges	$	1,146	$	1,164		$	3,800	$	7,388

Table Of Contents

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. Employee severance and related costs include severance benefits, notice pay, and outplacement services. These rebalance charges generally represent the aggregate of numerous unrelated rebalance plans which impact several employee groups, none of which is individually material to our financial position or results of operations. We determine termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicate termination benefits to the affected employees prior to the end of the quarter in which we record the charge. Special charges may also include expenses incurred related to acquisitions, excess facility costs, and asset related charges.

Approximately 61% of the employee severance and related costs for the nine months ended October 31, 2012 were paid during the period. We expect to pay the remainder during the fiscal year ending January 31, 2013 .

Substantially all of the employee severance and related costs for the nine months ended October 31, 2011 were paid during the fiscal year ending January 31, 2012 . There have been no significant modifications to the amount of these charges.

Other special charges for the nine months ended October 31, 2011 included costs of $3,967 related to consulting fees associated with our fiscal 2012 proxy contest.

Accrued special charges are included in accrued and other liabilities and other long-term liabilities in the condensed consolidated balance sheets. The following table shows changes in accrued special charges during the nine months ended October 31, 2012 :



	Accrued special charges as of		Charges during the nine months ended		Payments during the nine months ended			Accrued special charges as of
	January 31, 2012		October 31, 2012		October 31, 2012			October 31, 2012		(1	)
Employee severance and related costs	$	3,668	$	2,629	$	(4,700	)	$	1,597
Other costs	2,811		1,171		(824		)	3,158
Total accrued special charges	$	6,479	$	3,800	$	(5,524	)	$	4,755


⁽¹⁾	Of the $4,755 total accrued special charges as of October 31, 2012 , $2,299 represented the long-term portion, which primarily included accrued lease termination fees and other facility costs, net of sublease income and other long-term costs. The remaining balance of $2,456 represented the short-term portion of accrued special charges.


(12)	Other Income (Expense), Net —Other income (expense), net was comprised of the following:

(13) Related Party Transactions —Certain members of our Board of Directors also serve on the board of directors for some of our customers. Management believes the transactions between these customers and us were carried out on an arm’s-length basis. As of October 31, 2012 and January 31, 2012 , accounts receivable from these customers were not significant. The following table shows revenue recognized from these customers:



	Three months ended October 31,						Nine months ended October 31,

Revenues from customers	$	7,377		$	5,821		$	38,651		$	30,132
Percentage of total revenues	2.7		%	2.3		%	5.1		%	4.3		%


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

Table Of Contents



	Three months ended October 31,						Nine months ended October 31,
	2012			2011			2012			2011
Income tax expense (benefit)	$	1,148		$	(1,445	)	$	(835	)	$	(4,429	)
Effective tax rate	3.5		%	(6.4		)%	(1.1		)%	(20.5		)%

Generally, the provision for income taxes is the result of the mix of profits and losses earned in various 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 for interim reporting that we evaluate our provision for income tax expense (benefit) based on our projected results of operations for the full year, and record adjustments in each quarter. Such adjustments consider period specific items and a separate determination of tax expense for entities in our consolidated group that are projected to have losses for which no tax benefit will be recognized.

Our effective tax rate is (1.1)% for the nine months ended October 31, 2012 , after the inclusion of $(6,176) in net favorable period specific items. The period specific items primarily relate to reductions in liabilities for uncertain tax positions. For our full year forecast, we have projected a 3% effective tax rate. This rate is inclusive of period specific items recognized through October 31, 2012 . Our projected rate for the full year 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;

• Forecasted utilization of net operating loss carryforwards for which no previous benefit was recognized;

• Reduction in reserves for uncertain tax positions; and

• The application of tax incentives for research and development.

These differences are partially offset by:

• 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, our effective tax rate could fluctuate considerably on a quarterly basis, and could be significantly affected to the extent our actual mix of earnings among individual jurisdictions is different than our expectations.

As of October 31, 2012 , we had a liability of $27,706 for income taxes associated with uncertain income tax positions. Of this liability, $5,535 was classified as short-term liabilities in our condensed consolidated balance sheet as we generally anticipate the settlement of such liabilities will require payment of cash within the next twelve months. The remaining $22,171 of income tax associated with uncertain tax positions was classified as long-term liabilities. Certain liabilities may result in the reduction of deferred tax assets rather than settlement in cash. We are not able to reasonably estimate the timing of any cash payments required to settle the long-term liabilities and do not believe that the ultimate settlement of these liabilities will materially affect our liquidity.

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 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) tools — advanced computer software and emulation hardware systems used to automate the design, analysis, and testing of complex electro-mechanical systems, 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 or believe we can attain leading market share. Part of this approach includes developing new applications and exploring new markets where EDA companies have not generally 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 risk as a creditor, while increasing our potential for growth.

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 50% or more 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.

Known Trends and Uncertainties Impacting Future Results of Operations

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.

Ten accounts make up approximately 45% 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 first nine months of fiscal 2013 was not material. However, we do have exposures within our receivables portfolio to customers with weak credit ratings. These receivable 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.

Bookings during the first nine months of fiscal 2013 decreased by approximately 25% compared to the first nine months of fiscal 2012 primarily due to the timing of term license contract renewals. Bookings are the value of executed orders during a period for which revenue has been or will be recognized within six months for software products and within twelve months for emulation hardware systems, professional services, and training. Ten customers accounted for approximately 35% of total bookings for the first nine months of fiscal 2013 compared to 45% for the first nine months of fiscal 2012 . The number of new customers during the first nine months of fiscal 2013 , excluding PADS (our ready to use printed circuit board design tools) remained consistent with the levels experienced during the first nine months of fiscal 2012 .

Product Developments

During the nine months ended October 31, 2012 , 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 nine months of fiscal 2013 , 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. 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, business combinations, 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, 2012 .

System and Software



	Three months ended October 31,						Nine months ended October 31,
	2012		Change		2011		2012		Change		2011
Upfront license revenues	$	144.6	7	%	$	134.7	$	385.1	10	%	$	350.9
Ratable license revenues	21.7		10	%	19.7		70.5		16	%	60.6
Total system and software revenues	$	166.3	8	%	$	154.4	$	455.6	11	%	$	411.5

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 collectibility is not probable and recognize revenue on those licenses when cash is received. Ratable license revenues primarily consist of 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.

Ten customers accounted for approximately 60% of system and software revenues for the three months ended October 31, 2012 and 2011 and approximately 45% for the nine months ended October 31, 2012 and 2011 .

System and software revenues increase d for the three and nine months ended October 31, 2012 compared to the three and nine months ended October 31, 2011 primarily due to an increase in sales of emulation hardware systems.

For the three months ended October 31, 2012 and 2011 and for the nine months ended October 31, 2012 , no single customer accounted for 10% or more of total revenues. For the nine months ended October 31, 2011 , one customer accounted for 13% of total revenues.

System and software gross margin percentage was lower for the three months ended October 31, 2012 compared to the three months ended October 31, 2011 primarily due to a change in product mix that resulted from an increase in sales of lower gross margin emulation hardware systems.

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 lower margin offerings which are 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 and nine months ended October 31, 2012 compared to the three and nine months ended October 31, 2011 was driven by increased service revenues resulting from an increase in our installed base.

The changes in revenues in Pacific Rim, North America and Japan for the three and nine months ended October 31, 2012 compared to the three and nine months ended October 31, 2011 were the result of the timing and geographic location of contract renewals.

For the three months ended October 31, 2012 , approximately one-fourth of European and substantially all of Japanese revenues were subject to exchange rate fluctuations as they were booked in local currencies. For the nine months ended October 31, 2012 , approximately one-third of European and two-thirds of 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 nominal impact for the three and nine months ended October 31, 2012 compared to the three and nine months ended October 31, 2011 .

Table Of Contents

months ended October 31, 2011 . The increase from the nine months ended October 31, 2011 was primarily driven by expenses associated with acquired businesses.

We incur a substantial portion of our operating expenses outside the U.S. in various foreign currencies. We recognize additional operating expense in periods when the U.S. dollar weakens in value against foreign currencies and lower operating expenses in periods when the U.S. dollar strengthens in value against foreign currencies. We experienced favorable currency movements of approximately $4.7 in total operating expenses for the three months ended October 31, 2012 , compared to the three months ended October 31, 2011 , primarily due to movements in the euro and the Indian rupee, as well as other foreign currencies. We experienced favorable currency movements of approximately $12.3 in total operating expenses for the nine months ended October 31, 2012 , compared to the nine months ended October 31, 2011 , primarily due to movements in the euro and the Indian rupee, as well as other foreign currencies. The impact of these currency movements is reflected in the changes 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 PCB Solutions Limited Partnership (Frontline). Frontline is owned equally by Mentor and Orbotech, Ltd., an Israeli company.

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 and nine months ended September 30, 2012 and 2011 :

Other special charges for the nine months ended October 31, 2011 primarily consisted of $3.9 for advisory fees associated with our proxy contest.

Interest Expense

Interest expense decreased by $12.7 for the nine months ended October 31, 2012 compared to the nine months ended October 31, 2011 . The decrease was primarily due to the repayment of debt in April 2011 and the resulting loss 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

Table Of Contents

of the 6.25% Convertible Subordinated Debentures, and a write-off of $1.8 for the remaining portion of unamortized debt issuance costs.

Provision for Income Taxes



	Three months ended October 31,							Nine months ended October 31,
	2012		Change		2011			2012			Change		2011
Income tax provision (benefit)	$	1.1	(179	)%	$	(1.4	)	$	(0.8	)	(82	)%	$	(4.4	)

Generally, the provision for income taxes is the result of the mix of profits and losses earned in various 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. The provision considers that a significant amount of our earnings are in certain foreign operations, including our Irish subsidiaries. Accounting guidance requires for interim reporting that we evaluate our provision for income tax expense (benefit) based on our projected results of operations for the full year, and record adjustments in each quarter. Such adjustments consider period specific items and a separate determination of tax expense for entities in our consolidated group that are projected to have losses for which no tax benefit will be recognized.



	Three months ended October 31,						Nine months ended October 31,
	2012			2011			2012			2011
Effective Tax Rate	3		%	(6		)%	(1		)%	(20		)%
Net period specific items benefit	$	(0.9	)	$	(3.7	)	$	(6.2	)	$	(8.8	)
Effective tax rate without period specific items	6		%	10		%	7		%	20		%

For the nine months ended October 31, 2012 , we have a 7% effective tax rate without period specific items. This current period effective tax rate differs from our effective tax rate for the nine months ended October 31, 2011 due primarily to the application of the accounting guidance for interim periods with respect to jurisdictions with projected losses before tax for which no tax benefits will be recognized.

For our full year forecast, we have projected a 3% effective tax rate. This rate is inclusive of period specific items recognized through October 31, 2012 . Our projected 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;


•	Forecasted utilization of net operating loss carryforwards for which no benefit was previously recognized;


•	Reduction in reserves for uncertain tax positions; and


•	The application of tax incentives for research and development.

These differences are partially offset by:


•	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. Where the earnings of our foreign subsidiaries are not treated as permanently reinvested, 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 fully 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

Table Of Contents

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 statute of limitations is open for fiscal year 2010 and forward although net operating losses and credits from all years are subject to examination and adjustments for the three years following the year in which they were utilized. The statute of limitations remains open for years on or after fiscal 2008 in Japan and in Ireland.

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. Many of these events cannot be predicted, such as clarifications of tax law by administrative or judicial means, and it is often difficult to predict the final outcome or timing of resolution of any particular tax matter. 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.

We currently have sufficient funds for domestic operations and do not anticipate the need to repatriate funds associated with our permanently reinvested foreign earnings. As of October 31, 2012 , we have cash totaling $126.7 held by our foreign subsidiaries. A significant portion of our offshore cash is accessible without a significant tax cost as some of our foreign earnings were previously taxed in the U.S., and other foreign earnings may be sheltered from U.S. tax by net operating loss and tax credit carryforwards. To the extent our foreign earnings are not permanently reinvested, we have provided for the tax consequences that would ensue upon their repatriation. In the event funds which are treated as permanently reinvested are repatriated, we may be required to accrue and pay additional U.S. taxes to repatriate these funds.

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 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 that we will be able to raise debt or equity capital on acceptable terms, if at all.

Cash used in investing activities	$	(37.5	)	$	(26.2	)
Cash used in financing activities	$	(0.1	)	$	(30.8	)

Operating Activities

Cash flows from operating activities consist of our net income, adjusted for certain non-cash items and changes in operating assets and liabilities. Our cash flows from operating activities are 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	October 31, 2012		January 31, 2012
Trade accounts receivable, net	$	404.8	$	354.9
Term receivables, long-term	$	207.6	$	220.4
Average days sales outstanding in trade accounts receivable, net	136 days		100 days
Average days sales outstanding in trade accounts receivable, net, excluding the current portion of term receivables	58 days		38 days

The overall increase in the average days sales outstanding in trade accounts receivable, net for both measures as of October 31, 2012 was primarily due to a decrease in revenue and the timing of billings under customer contracts in the third quarter of fiscal 2013 compared to the fourth quarter of fiscal 2012 .

The current portion of term receivables was $232.9 as of October 31, 2012 and $221.4 as of January 31, 2012 . 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 $440.5 as of October 31, 2012 compared to $441.8 as of January 31, 2012 .

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 $19.4 for the nine months ended October 31, 2012 compared to $28.3 for the nine months ended October 31, 2011 . 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 2013 .

Accrued Payroll and Related Liabilities



As of	October 31, 2012		January 31, 2012
Accrued payroll and related liabilities	$	68.3	$	112.3

The decrease in accrued payroll and related liabilities as of October 31, 2012 compared to January 31, 2012 was primarily due to incentive payments made during fiscal 2013 on fiscal 2012 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 due to the full year achievement of results.

Investing Activities

Table Of Contents

Cash used in investing activities for the nine months ended October 31, 2012 primarily consisted of cash paid for capital expenditures.

Expenditures for property, plant, and equipment increased to $35.6 for the nine months ended October 31, 2012 compared to $25.1 for the nine months ended October 31, 2011 . The expenditures for property, plant, and equipment for the nine months ended October 31, 2012 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 2013 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.

Financing Activities

For the nine months ended October 31, 2012 , cash used in financing activities consisted primarily of repurchases of our common stock and repayments of short-term borrowings offset in part by proceeds from the issuance of common stock.

In April 2011, we announced a share repurchase program under which we may repurchase up to $150.0 of our common stock over a three year period through April 2014. In February 2012, the Board of Directors approved an increase in the amount we may repurchase under this program from $150.0 to $200.0. During the nine months ended October 31, 2012 , we repurchased 1.4 shares of common stock for $20.0 under this program. Under the terms of our revolving credit facility, the amount we can repurchase under the share repurchase program is limited to $50.0 plus 70% of our cumulative net income for periods after January 31, 2011. An additional $77.6 of our stock can be repurchased under this limit as of October 31, 2012 .

Other factors affecting liquidity and capital resources

4.00% Debentures due 2031

In April 2011 , we issued $253.0 of 4.00% Convertible Subordinated Debentures due 2031 (4.00% Debentures). 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 12.3 shares as of October 31, 2012 .

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. Any make whole premium would have the effect of increasing the amount of any cash, securities, or other property or assets otherwise due to holders of debentures upon conversion.

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.

For further information on the 4.00% Debentures, see Note 6 . “ Notes Payable ” in Part I, Item 1. “Financial Statements.”

Revolving Credit Facility

Table Of Contents

In April 2011 , we entered into a syndicated, senior, unsecured, P4Y -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% .

We had no borrowings against the revolving credit facility during the nine months ended October 31, 2012 . The base interest rate was 4.5% as of October 31, 2012 .

For further information on our revolving credit facility, see Note 5 . “ Short-Term Borrowings ” in Part I, Item 1. “Financial Statements.”

OFF-BALANCE SHEET ARRANGEMENTS

OUTLOOK FOR FISCAL 2013

We expect revenues for the fourth quarter of fiscal 2013 to be approximately $343.0 million with earnings per share for the same period of approximately $0.54 per diluted share. For the full fiscal year 2013 , we expect revenues of approximately $1.1 billion with earnings per share of $1.22 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 October 31, 2012 .



Principal (notional) amounts in United States dollars	Carrying Amount	Average Fixed Interest Rate
Cash equivalents - fixed rate	$14.3	5.27%

We had convertible subordinated debentures with a principal balance of $253.0 outstanding with a fixed interest rate of 4.00% as of October 31, 2012 and October 31, 2011 . 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 October 31, 2012 and October 31, 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)	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% ; 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 October 31, 2012 and 2011 , 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 5 . “ Short-Term Borrowings ” in Part I, Item 1. “Financial Statements.”

We had other short-term borrowings of $ 1.3 outstanding as of October 31, 2012 and $ 5.3 as of October 31, 2011 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.

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

Table Of Contents

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.

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 revenues 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 United States 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 2013 ” 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 2013 ,” 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 2009, the economic conditions in Japan caused by the 2011 earthquake and tsunami, or the ongoing European debt crisis, 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. In addition, significant customer payment defaults or bankruptcies could materially harm our business.

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.

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 canceled. The conversion rate can also be affected by the tendency of some of our customers to wait until the end of a fiscal quarter in an attempt 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 transaction types 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

Table Of Contents

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 transaction types entered into where we recognize software revenues in different ways as required by accounting rules: as payments become due and payable, on a cash basis, ratably over the license term, or 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 occur as expected, our gross margins and operating results could be materially adversely impacted.

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, or may temporarily provide significantly higher discounts to attempt to replace our products in certain areas of the customers' design flow. 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.

We may experience difficulty in manufacturing our emulation hardware.

We currently contract with a single manufacturer to assemble our hardware emulation products and purchase some components from a single supplier(s). As a result, we may be exposed to delays in production and delivery of our emulation products due to delays in receiving components or manufacturing constraints, components rejected that do not meet our standards, low yields of ICs, subassemblies, or printed circuit boards, or other delays in the manufacturing process. For single source parts we purchase for our emulation products, there can be no assurance that, if a supplier cannot deliver, a second source can be found on a timely basis.

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

We typically generate over 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.

Table Of Contents

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 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. Sales of our products and services are 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. Long sales cycles for our hardware products may subject us to risks over which we have limited control, including insufficient, excess, or obsolete inventory, variations in inventory valuation, and fluctuations in quarterly operating results.

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.

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. To the extent that we do not recognize as much revenue at the beginning of the license period as in the past, such a change in accounting rules could have a material adverse impact on our short-term results.

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 may have additional tax liabilities.

Significant judgments and estimates are required in determining the provision for income taxes and other tax liabilities around the world. 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 that could result if our tax positions were challenged by the Internal Revenue Service (IRS) and other tax authorities. The tax authorities in the U.S. and other countries where we do business regularly examine our income and other tax returns. The ultimate outcome of these examinations cannot be predicted with certainty. Should the IRS or other 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 provisions under U.S. generally accepted accounting principles. Income tax expense (benefit) for interim quarters is based on a forecast of our global tax rate for the year, including a separate determination for entities with losses for which no tax benefit is obtained. This forecast 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 future events may be treated as discrete to the period in which they occur. Our income tax rate can be materially impacted, for example, by the geographical mix of our profits and losses, changes in our business, such as internal restructuring and acquisitions, changes in tax laws and accounting guidance, and other regulatory, legislative or judicial developments, tax audit determinations, changes in our tax positions, changes in our intent and capacity to permanently reinvest foreign earnings, changes to our transfer pricing practices, tax deductions attributed to equity compensation, and changes in our valuation allowance for deferred tax assets. 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 our control system will detect all errors and instances of fraud, if any. 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;


•	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.

Our competitors may acquire technology or other companies that impact our business.

Our competitors may acquire technology or companies offering competing or complementary product offerings which could adversely impact our ability to compete in the marketplace. They may be able to deliver better or broader product offerings, offer better pricing, or otherwise make it more desirable for our customers to buy more of the tools in their design flow from the competitor after the acquisition. In addition, our competitors may purchase companies or technology that we had an interest in acquiring, which could limit our expansion into certain market segments.

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 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. In addition, despite our measures to limit piracy, other parties may attempt to illegally copy or use our products, which could result in lost revenue.

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.

Intellectual property infringement actions may harm our business.

Patent holders are making increasing efforts to monetize their patent portfolios. Intellectual property infringement claims against us directly, or where we contractually must defend our customers, could result in costly litigation and consume significant time of employees and management. IP litigation could harm our business, either due to damage awards, the need to license technology on what might be unfavorable business terms, injunctions that could stop or delay future shipments, or the need to redesign our technology.

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 operations in Israel, 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.

Our business is subject to the risk of natural disasters.

We have sales and research and development offices around the world which may be adversely affected by weather, earthquakes or other natural disasters. If a natural disaster occurs at or near any of our offices, our operations may be interrupted, which could adversely impact our business and results of operations. In addition, if a natural disaster impacts a significant number of our customers, our business and results of operations could be adversely impacted.

If our IT security measures are breached, our information systems may be perceived as being insecure, which could harm our business and reputation.

Our products and services involve the storage and transmission of proprietary information owned by us and our customers. We have sales and research and development offices throughout the world. Our operations are dependent upon the connectivity of our operations throughout the world. Despite our security measures, our information technology and infrastructure may be vulnerable to cyber-attacks or breached due to employee errors or other disruptions that could result in unauthorized disclosure of sensitive information and could significantly interfere with our business operations. Breaches of our security measures could expose us to a risk of loss or misuse of this information, adverse publicity, violations of privacy laws, and litigation. Because techniques used to obtain unauthorized access or to sabotage information systems change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventive measures. In addition, if we select a vendor that used cyber storage of information as part of their service or product offerings, despite our attempts to validate the security of such services, proprietary information may be misappropriated by third parties. If there is an actual or perceived breach of our security, or the security of one of our vendors, the market perception of the effectiveness of our security measures could be harmed and we could suffer damage to our reputation or our business, or lose existing customers and impair our ability to obtain new customers.

Our shareholder rights plan may have anti-takeover effects.

In December 2011, we extended the term of our 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 our shareholder rights

Table Of Contents

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.

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 October 31, 2012 , we had $257.2 million of outstanding indebtedness, which includes $253.0 million of 4.00% Convertible Subordinated Debentures due 2031, $1.4 million in other notes payable, and $2.8 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 or by our competitors 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.
