Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation We prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (GAAP) for complete financial statements and these unaudited financial statements should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended November 30, 2012. We made no significant changes in the application of our significant accounting policies that were disclosed in our Annual Report on Form 10-K for the fiscal year ended November 30, 2012. We have prepared the accompanying unaudited condensed consolidated financial statements on the same basis as the audited financial statements included in our Annual Report on Form 10-K, and these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of the interim periods presented. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full fiscal year. During the fourth quarter of fiscal year 2012 and the first quarter of fiscal year 2013, we completed the divestitures of the ten product lines which were not considered core product lines of our business: Actional, Artix, DataXtend, FuseSource, ObjectStore, Orbacus, Orbix, Savvion, Shadow and Sonic. The divestitures were part of the new strategic plan (the "Plan") we announced during fiscal year 2012. After the announcement of the Plan, we began reporting our results in two reportable segments: Core and non-Core. Since the non-Core segment ceased to exist during the first quarter of fiscal year 2013, after the closing of all these divestitures, we now operate as one reportable segment. In addition, the revenues and direct expenses of the product lines divested are included in discontinued operations in our condensed consolidated statements of income, including prior period amounts which have been revised to reflect the presentation. In June 2013, we entered into a definitive purchase and sale agreement to divest our Apama product line to Software AG. The target market, deployment and sales model for the Apama product line differs significantly from those of our application development platform and the divestiture allows us to focus entirely on providing leading cloud and mobile application development technologies through a single cohesive platform. The sale is expected to close in July 2013 for $44.3 million. As of May 31, 2013, we met the requirements to classify the sale of this product line as both held for sale and discontinued operations in the consolidated financial statements. The revenues and direct expenses of the Apama product line are included in discontinued operations in our consolidated statements of income, including prior period amounts which have been revised to reflect the presentation. Recent Accounting Pronouncements In September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-08, Intangibles – Goodwill and Other (Topic 350) – Testing Goodwill for Impairment (ASU 2011-08), to allow entities to use a qualitative approach to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If after performing the qualitative assessment an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step goodwill impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step goodwill impairment test. ASU 2011-08 is effective for us in fiscal year 2013. We adopted ASU 2011-08 during the first quarter of fiscal year 2013 for our annual impairment test, which occurs in the first quarter of our fiscal year. The adoption did not have any impact on our financial position, results of operations or cash flows. In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220) – Presentation of Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. In December 2011, the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220) – Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05 (ASU 2011-12), which defers the effective date of only those changes in ASU 2011-05 that relate to the presentation of reclassification adjustments. We adopted ASU 2011-05 in our first quarter of fiscal year 2013, and applied it retrospectively. We elected to report comprehensive income as a separate, but consecutive statement to net income. The adoption of ASU 2011-05 did not have any impact on our financial position, results of operations or cash flows. In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220) – Reporting of Amounts Reclassified out of Accumulative Other Comprehensive Income (ASU 2013-02), which replaces the presentation requirements for reclassifications out of accumulated other comprehensive income in ASU 2011-05 and ASU 2011-12. ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to present significant amounts reclassified out of accumulated other comprehensive income by respective line items of net income if the amount reclassified is required to be reclassified to net income in its entirety. We adopted ASU 2013-02 in the second quarter of fiscal year 2013 and applied it prospectively. The adoption of ASU 2013-02 did not have any impact on our financial position, results of operations or cash flows.

Such amounts are classified on our condensed consolidated balance sheets as follows (in thousands):

Total	$	218,387	$	37,417	$	26,500	$	301,792	$	53,425	$	26,321

The valuation methodologies for our auction rate securities (ARS) are described in Note 4. Based on these methodologies, we determined that the fair value of our ARS investments is $26.5 million and $26.3 million at May 31, 2013 and November 30, 2012, respectively. The temporary impairment recorded in accumulated other comprehensive loss to reduce the value of our available-for-sale ARS investments was $4.2 million and $4.4 million at May 31, 2013 and November 30, 2012, respectively.

We will not be able to access the funds associated with our ARS investments until a future auction for these ARS is successful, we sell the securities in a secondary market, or they are redeemed by the issuer. As such, these remaining investments currently lack short-term liquidity and are therefore classified as long-term investments on the condensed consolidated balance sheets at May 31, 2013 and November 30, 2012.

Based on our cash, cash equivalents and short-term investments balance of $255.8 million, expected operating cash flows and the availability of funds under our revolving credit facility, we do not anticipate that the lack of liquidity associated with our ARS will adversely affect our ability to conduct business and we believe that we have the ability to hold the affected securities throughout the currently estimated recovery period. Therefore, the impairment of these securities is considered only temporary in nature. If the credit rating of either the security issuer or the third-party insurer underlying the investments deteriorates significantly, we may be required to adjust the carrying value of the ARS through an other-than-temporary impairment charge to earnings.

The fair value of debt securities by contractual maturity is as follows (in thousands):



	May 31, 2013		November 30, 2012
Due in one year or less ⁽¹⁾	$	46,705	$	55,001
Due after one year	17,212		24,745
Total	$	63,917	$	79,746


(1)	Includes ARS which are tendered for interest-rate setting purposes periodically throughout the year. Beginning in February 2008, auctions for these securities began to fail, and therefore these investments currently lack short-term liquidity. The remaining contractual maturities of these securities range from 11 to 30 years.

Investments with continuous unrealized losses and their related fair values are as follows at May 31, 2013 (in thousands):



	Less Than 12 Months				12 Months or Greater					Total
	Fair Value		Unrealized Losses		Fair Value		Unrealized Losses			Fair Value		Unrealized Losses
Auction rate securities – municipal bonds	$	—	$	—	$	23,562	$	(3,588	)	$	23,562	$	(3,588	)
Auction rate securities – student loans	—		—		2,938		(562		)	2,938		(562		)
Total	$	—	$	—	$	26,500	$	(4,150	)	$	26,500	$	(4,150	)

Investments with continuous unrealized losses and their related fair values are as follows at November 30, 2012 (in thousands):



	Less Than 12 Months					12 Months or Greater					Total
	Fair Value		Unrealized Losses			Fair Value		Unrealized Losses			Fair Value		Unrealized Losses
State and municipal bond obligations	$	5,818	$	(1	)	$	472	$	(1	)	$	6,290	$	(2	)
Auction rate securities – municipal bonds	—		—			23,420		(3,755		)	23,420		(3,755		)
Auction rate securities – student loans	—		—			2,901		(599		)	2,901		(599		)
Corporate bonds	2,607		(1		)	—		—			2,607		(1		)
Total	$	8,425	$	(2	)	$	26,793	$	(4,355	)	$	35,218	$	(4,357	)

The unrealized losses associated with state and municipal bond obligations and corporate bonds are attributable to changes in interest rates. The unrealized losses associated with ARS are discussed above. Management does not believe any unrealized losses represent other-than-temporary impairments based on our evaluation of available evidence as of May 31, 2013 and November 30, 2012.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

We use forward contracts that are not designated as hedging instruments to hedge economically the impact of the variability in exchange rates on accounts receivable and collections denominated in certain foreign currencies. We generally do not hedge the net assets of our international subsidiaries. All forward contracts are recorded at fair value in other current assets on the condensed consolidated balance sheets at the end of each reporting period and expire within 90 days. In the three and six months ended May 31, 2013 and May 31, 2012, realized and unrealized gains (losses) of $0.6 million, $(0.5) million, $2.5 million and $0.3 million, respectively, from our forward contracts were recognized in other income (expense) in the condensed consolidated statements of income. These losses were substantially offset by realized and unrealized gains on the offsetting positions.

The table below details outstanding foreign currency forward contracts where the notional amount is determined using contract exchange rates (in thousands):



	May 31, 2013					November 30, 2012
	Notional Value		Fair Value			Notional Value		Fair Value

When developing fair value estimates, we maximize the use of observable inputs and minimize the use of unobservable inputs. When available, we use quoted market prices to measure fair value. The valuation technique used to measure fair value for our Level 1 and Level 2 assets is a market approach, using prices and other relevant information generated by market transactions involving identical or comparable assets. If market prices are not available, the fair value measurement is based on models that use primarily market based parameters including yield curves, volatilities, credit ratings and currency rates. In certain cases where market rate assumptions are not available, we are required to make judgments about assumptions market participants would use to estimate the fair value of a financial instrument.

The valuation technique used to measure fair value for our Level 3 assets, which consists of our ARS, is primarily an income approach, where the expected weighted average future cash flows are discounted back to present value for each asset. The significant unobservable inputs used in the fair value measurement of our ARS are the probability of earning the maximum rate until maturity, the probability of principal return prior to maturity, the probability of default, the liquidity risk premium and the recovery rate in default. Generally, interrelationships are such that a change in the assumptions used for the probability of principal return prior to maturity is accompanied by a directionally opposite change in one or more the following assumptions: the probability of earning the maximum rate until maturity, the probability of default and the liquidity risk premium. The recovery rate in default is somewhat independent and based upon the ARS' specific underlying assets and published recovery rate studies.

One issuer of our ARS is currently in default, but the underlying bond insurer is making interest payments on the issuer's behalf. In this situation, we used a market approach, where the significant unobservable inputs are the market credit default swap spread and the credit rating of the insurer.

The following table provides additional quantitative information about the unobservable inputs used in our Level 3 valuations as of May 31, 2013:



	Valuation Technique	Unobservable Input	Range (Weighted Average)
Auction rate securities	Discounted cash flow	Probability of earning the maximum rate until maturity	0.3% - 9.4% (1.6%)
		Probability of principal return prior to maturity	79.1% - 95.2% (88.6%)
		Probability of default	4.0% - 12.8% (9.8%)
		Liquidity risk premium	4.0%
		Recovery rate in default	50% - 70% (56.5%)
	Market valuation	Market credit default swap spread of insurer	2.8%
		Credit rating of insurer	AA-

Significant increases or decreases in the underlying assumptions used to value the ARS could significantly increase or decrease the fair value estimates recorded in the consolidated balance sheets.

We have classified contingent consideration related to the Rollbase, Inc. acquisition (Rollbase), which occurred in May 2013 (Note 7), within Level 3 of the fair value hierarchy because the fair value is derived using significant unobservable inputs, which include discount rates and probability-weighted cash flows. We determined the fair value of our contingent consideration obligations based on a probability-weighted income approach derived from probability assessments of the attainment of certain milestones. We establish discount rates to be utilized in our valuation models based on the cost to borrow that would be required by a market participant for similar instruments. In determining the probability of attaining certain milestones, we utilize data regarding similar milestone events from our own experience. On a quarterly basis, we will reassess the probability factors associated with the milestones for our contingent consideration obligations. Significant judgment is employed in determining the appropriateness of these key assumptions as of the acquisition date and for each subsequent period.

The key assumptions as of May 31, 2013 related to the contingent consideration for the acquisition of Rollbase used in the model are probabilities in excess of 95% that the milestones associated with the contingent consideration will be achieved and a discount rate of 4.8%. A decrease in the probabilities of achievement could result in a significant decrease to the estimated fair value of the contingent consideration liability.

During the three months ended May 31, 2013, there was no change in the fair value of the contingent consideration liability related to the Rollbase acquisition.

The following table reflects the activity for our financial assets measured at fair value using Level 3 inputs for each period presented (in thousands):



	Three Months Ended					Six Months Ended
	May 31, 2013		May 31, 2012			May 31, 2013			May 31, 2012
Balance, beginning of period	$	26,442	$	33,343		$	26,321		$	33,539
Redemptions and repurchases	—		—			(25		)	(225		)
Transfer to Level 2 fair value measurement	—		(2,700		)	—			(2,700		)
Unrealized gains included in accumulated other comprehensive loss	58		805			204			834
Balance, end of period	$	26,500	$	31,448		$	26,500		$	31,448

During the second quarter of fiscal year 2012, we received a redemption notice for one of our ARS at par value. We transferred the ARS to a Level 2 fair value measurement, as the value at May 31, 2012 was based on observable inputs.

Nonrecurring Fair Value Measurements

The following table details our nonrecurring fair value measurements at November 30, 2012 (in thousands):



			Fair Value Measurements Using
	Total Fair Value		Level 1		Level 2		Level 3		Total Losses
Disposal group	$	16,487	$	—	$	16,487	$	—	$	8,601

The disposal group included the assets and liabilities held for sale of the Artix, Orbacus and Orbix product lines, which had a fair value of $16.5 million as of November 30, 2012. The carrying value at November 30, 2012 of $25.1 million was written down to fair value, less costs to sell, resulting in a loss of $8.6 million. The loss was recorded in income (loss) from discontinued operations in fiscal year 2012. The assets and liabilities held for sale were divested in the first quarter of fiscal year 2013 (Note 6).

We evaluate all of our assets held for sale using undiscounted cash flow models or other valuation models, such as comparative transactions and market multiples, to determine their fair values. However, a market approach was more heavily used to value the assets held for sale related to the divestitures of our non-core product lines. As bid and transaction values became apparent as we moved through the marketing and divestiture process, the fair values of the assets held for sale was established. The impairment loss recorded for the Artix, Orbacus and Orbix product lines was primarily based on our expectations of a sale price as compared to our estimation of the net assets to be sold at closing.

Goodwill and Intangible Assets Disclosure [Abstract]

Intangible Assets and Goodwill

Intangible Assets

Intangible assets are comprised of the following significant classes (in thousands):



	May 31, 2013							November 30, 2012
	Gross Carrying Amount		Accumulated Amortization			Net Book Value		Gross Carrying Amount		Accumulated Amortization			Net Book Value
Purchased technology	$	44,652	$	(35,509	)	$	9,143	$	42,520	$	(40,066	)	$	2,454
Customer-related and other	19,529		(17,242		)	2,287		26,477		(23,812		)	2,665
Total	$	64,181	$	(52,751	)	$	11,430	$	68,997	$	(63,878	)	$	5,119

As of the result of the Rollbase acquisition in May 2013 (Note 7), we recorded $7.8 million of purchased technology and $0.2 million of customer relationships as intangible assets during the six months ended May 31, 2013. These intangible assets have a weighted average useful life of 4.9 years. This was offset by a decrease in the gross carrying amount of our intangible assets due to the intangible assets held for sale as of May 31, 2013 (Note 6).

In the three and six months ended May 31, 2013, amortization expense related to intangible assets was $0.3 million and $0.6 million, respectively. In the three and six months ended May 31, 2012, amortization expense related to intangible assets was $0.3 million and $0.8 million, respectively.

Future amortization expense for intangible assets as of May 31, 2013, is as follows (in thousands):



Remainder of 2013	$	1,480
2014	2,638
2015	2,409
2016	1,906
2017	1,906
Thereafter	1,091
Total	$	11,430

Goodwill

Changes in the carrying amount of goodwill for the six months ended May 31, 2013, are as follows (in thousands):



Balance, November 30, 2012	$	226,110
Additions	4,798
Goodwill transfered to assets held for sale	(6,377		)
Translation adjustments	(91		)
Balance, May 31, 2013	$	224,440

The addition to goodwill during fiscal year 2013 is related to the acquisition of Rollbase in May 2013 (Note 7). The transfer of goodwill to assets held for sale is related to the disposition of the Apama product line (Note 6).

During the first quarter of fiscal year 2013, we completed our annual testing for impairment of goodwill and, based on those tests, concluded that no impairment of goodwill existed as of December 15, 2012. During the second quarter of fiscal year 2013, we evaluated the impact of the disposition of the Apama product line, which is part of our single reportable segment, on goodwill and concluded that no impairment existed. Through the date and time our condensed consolidated financial statements were issued, no other trigger events have occurred that would indicate a potential impairment of goodwill exists.

- Definition

The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final. May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.

Discontinued Operations and Disposal Groups [Abstract]

Divestitures

Under the Plan, we announced we would divest all product lines which are not considered core product lines of our business: Actional, Artix, DataXtend, FuseSource, ObjectStore, Orbacus, Orbix, Savvion, Shadow and Sonic. The FuseSource and Shadow product lines were divested in fiscal year 2012. The remaining product lines were divested in the first quarter of fiscal year 2013.

In June 2013, we entered into a definitive purchase and sale agreement to divest our Apama product line to Software AG. The sale is expected to close in July 2013 for $44.3 million. As of the end of the fiscal second quarter of 2013, we met the requirements to classify the Apama product line as both held for sale and discontinued operations in the condensed consolidated financial statements.

Revenues and direct expenses of the divested product lines and the Apama product line have been reclassified as discontinued operations for all periods presented. The fiscal year 2012 results include revenues and direct expenses of all divested product lines and the Apama product line, since we earned revenues and incurred direct expenses for all or part of fiscal year 2012 for each of those product lines. The fiscal year 2013 results include the revenues and direct expenses of Apama and the divested product lines which had not occurred prior to the start of fiscal year 2013.

The components included in discontinued operations on the condensed consolidated statements of income are as follows (in thousands):



	Three Months Ended						Six Months Ended

Apama

The assets and liabilities being sold to Software AG are classified as assets and liabilities held for sale on the condensed balance sheet as of May 31, 2013 and are recorded at the lower of their carrying values or fair values less costs to sell. The major categories of the assets and liabilities held for sale are as follows (in thousands):



Assets:
Accounts receivable	$	3,672
Other current assets	165
Goodwill and intangible assets	6,990
Other long-term assets	409
Total assets held for sale	$	11,236
Liabilities:
Deferred revenue	$	4,012
Total liabilities held for sale	$	4,012

Artix, Orbacus and Orbix

In the first quarter of fiscal year 2013, we entered into a definitive purchase and sale agreement to divest our Artix, Orbacus and Orbix product lines to a subsidiary of Micro Focus International plc (Micro Focus). The divestiture of these product lines was part of the Plan. The sale closed in February 2013 for total consideration of $15.0 million.

The gain on sale of the Artix, Orbacus and Orbix product lines is calculated as follows (in thousands):



Purchase price	$	15,000
Less: transaction costs	826
Less: indemnification obligation	1,000
Less: net assets
Accounts receivables	2,300
Goodwill and intangible assets	24,325
Other assets	20
Impairment reserve	(8,601		)
Deferred revenue	(5,893		)
Gain on sale	1,023
Tax provision	—
Gain on sale, net of tax	$	1,023

In February 2013, upon the closing of the sale of Artix, Orbacus and Orbix, we amended the definitive purchase and sale agreement with Micro Focus to provide an additional indemnification obligation with respect to a specified vendor. The fair value of the indemnification obligation on the date the sale closed and the carrying value at May 31, 2013 is $1.0 million, and is included in other accrued liabilities in the condensed consolidated balance sheet. Our maximum indemnification obligation with respect to this matter is $11.3 million. The term of the indemnification is indefinite; however, we expect the matter to be substantially resolved within the next nine months.

In the fourth quarter of fiscal year 2012, we recorded an $8.6 million impairment loss on the Artix, Orbacus and Orbix assets held for sale based on our expectations of a sales price as compared to our estimation of the net assets to be sold at closing. The impairment loss was recorded as a reserve against the assets held for sale as of November 30, 2012. The gain recorded in the first quarter of fiscal year 2013 was the result of differences in our estimation of net assets to be sold at closing versus the actual value of the net assets sold at closing.

Actional, DataXtend, ObjectStore, Savvion and Sonic

In the fourth quarter of fiscal year 2012, we entered into a definitive purchase and sale agreement to divest our Actional, DataXtend, Savvion and Sonic product lines to the investment arm of Trilogy Enterprises. In December 2012, the agreement was amended to include the sale of our ObjectStore product line. The divestiture of these product lines was part of the Plan. The sale closed in December 2012 for total consideration of $60.5 million.

The gain on sale of the Actional, DataXtend, ObjectStore, Savvion and Sonic product lines is calculated as follows (in thousands):



Purchase price	$	60,500
Less: transaction costs	1,211
Less: net assets
Accounts receivables	12,004
Goodwill and intangible assets	31,693
Other assets	976
Deferred revenue	(19,168		)
Other liabilities	(299		)
Gain on sale	34,083
Tax provision	15,349
Gain on sale, net of tax	$	18,734

- Definition

The entire disclosure for the facts and circumstances leading to the completed or expected disposal, manner and timing of disposal, the gain (loss) recognized in the income statement and the income statement caption that includes that gain (loss), amounts of revenues and pretax profit or loss reported in discontinued operations, the segment in which the disposal group was reported, and the classification (whether sold or classified as held for sale) and carrying value of the assets and liabilities comprising the disposal group. Includes all disposal groups, including those classified as components of the entity (discontinued operations).

Business Combinations [Abstract]

Business Combinations

On May 24, 2013, we acquired 100% of the equity interests in Rollbase, Inc. (Rollbase), a privately held software vendor based in Saratoga, California, for $9.9 million. The purchase consideration consisted of $9.5 million in cash paid and $0.4 million of contingent consideration, expected to be paid out over a two year period. The fair value of the contingent consideration was estimated to be $0.4 million at the date of acquisition. Rollbase provides Application Platform-as-a-Service (aPaas) technology that allows the rapid design, development and deployment of on-demand business applications. The purpose of the acquisition was to further the Plan in which we intend to become a leading provider of a next-generation, context-aware application development and deployment platform in the Cloud for the aPaas market. The acquisition was accounted for as a business combination, and accordingly, the results of operations of Rollbase are included in our operating results from the date of acquisition. We paid the purchase price in cash from available funds.

The preliminary allocation of the purchase price is as follows (in thousands):



	Total			Life
Cash	$	50
Acquired intangible assets	7,960			1 to 5 years
Goodwill	4,798
Deferred taxes	(2,921		)
Accounts payable and other liabilities	(8		)
Net assets acquired	$	9,879

The purchase consideration includes contingent consideration payable by the Company based on the achievement of certain milestones. The Company determined the fair value of the contingent consideration obligations by calculating the probability-weighted earn-out payments based on the assessment of the likelihood that the milestones will be achieved. The probability-weighted earn-out payments were then discounted using a discount rate commensurate with the credit risk of the Company.

The stock purchase agreement included contingent earn-out provisions requiring the Company to make payments to former Rollbase owners now employed by the Company. We have concluded that the earn-out provisions for the individuals now employed by the Company, which total approximately $5.0 million, are compensation arrangements and we will accrue the maximum payouts ratably over the two year performance period, as we believe it is probable that the criteria will be met.

We recorded the excess of the purchase price over the identified tangible and intangible assets as goodwill. We believe that the investment value of the future enhancement of our product and solution offerings created as a result of this acquisition has principally contributed to a purchase price that resulted in the recognition of $4.8 million of goodwill, which is not deductible for tax purposes. The preliminary fair value estimates of the acquired assets and liabilities are based upon preliminary calculations and valuations and our estimates and assumptions are subject to change as we obtain additional information for our estimates during the measurement period (up to one year from the acquisition date). The areas of those preliminary estimates that are not yet finalized relate to identifiable intangible assets and acquired deferred tax liabilities.

We incurred approximately $1.3 million of acquisition-related costs which are included in acquisition-related expenses in our consolidated statement of operations for the three and six months ended May 31, 2013. This amount includes a $1.0 million termination fee related to a pre-existing license arrangement between Rollbase and another third-party.

We have not disclosed the amount of revenues and earnings of Rollbase since acquisition, nor pro forma financial information, as those amounts are not significant to our condensed consolidated financial statements.

- Definition

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

Stock-based compensation expense reflects the fair value of stock-based awards measured at the grant date and recognized over the relevant service period. We estimate the fair value of each stock-based award on the measurement date using either the current market price of the stock or the Black-Scholes option valuation model. The Black-Scholes option valuation model incorporates assumptions as to stock price volatility, the expected life of options, a risk-free interest rate and dividend yield. We recognize stock-based compensation expense on a straight-line basis over the service period of the award, which is generally 4 or 5 years for options and 3 years for restricted stock units and restricted stock awards.

The following table provides the classification of stock-based compensation as reflected in our condensed consolidated statements of income (in thousands):

Total stock-based compensation	$	5,881	$	6,669	$	10,787	$	13,760

During the second quarter of fiscal year 2013, in connection with the divestiture of the Apama product line, we entered into transition agreements with five executives. As part of the agreements, the executives are entitled to accelerated vesting of certain stock-based awards upon the completion of the divestiture. Due to the anticipated accelerated vesting, we recognized additional stock-based compensation of $0.6 million in the three and six months ended May 31, 2013 in discontinued operations.

During the six months ended May 31, 2012, the employment of three of our executives terminated. As part of the separation agreements, the executives were entitled to accelerated vesting of certain stock-based awards. Due to the separation and accelerated vesting, we recognized additional stock-based compensation of $1.2 million and $1.8 million in the three and six months ended May 31, 2012, respectively.

Restructuring Charges

Restructuring Charges [Abstract]

Restructuring Charges

2012 Restructuring

In the second quarter of fiscal year 2012, our management approved, committed to and initiated certain operational restructuring initiatives to reduce annual costs, including the simplification of our organizational structure and the consolidation of facilities. In addition, as part of the Plan, we have divested the product lines not considered core to our business. Our restructuring actions include both our cost reduction efforts and qualifying costs associated with our divestitures.

Restructuring expenses primarily relate to employee costs, including severance, health benefits, outplacement services and transition divestiture arrangements, but excluding stock-based compensation. Facilities costs include fees to terminate lease agreements and costs for unused space, net of sublease assumptions. Other costs include costs to terminate automobile leases of employees included in the workforce reduction, asset impairment charges for assets no longer deployed as part of cost reduction strategies, costs for unused software licenses as part of the workforce reduction and other costs directly associated with the restructuring actions taken.

As part of the 2012 restructuring, for the three and six months ended May 31, 2013, we incurred expenses totaling $2.8 million and $4.1 million, respectively. Of the $2.8 million total expenses for the second quarter of fiscal year 2013, $0.2 million represents excess facilities and other costs and $2.6 million represents employee severances and related benefits. During the second quarter of fiscal year 2013, as a result of the product divestitures completed in the fourth quarter of fiscal year 2012 and the first quarter of fiscal year 2013, we initiated additional cost reduction actions related to excess facilities and employee redundancy. Of the $4.1 million total expenses for the first six months of fiscal year 2013, $1.1 million represents excess facilities and other costs and $3.0 million represents employee severances and related benefits. The expenses are recorded as restructuring expenses in the condensed consolidated statements of income, with the exception of $0.4 million included in income (loss) from discontinued operations for the six months ended May 31, 2013. Cumulative expenses of the 2012 restructuring through the first six months of fiscal year 2013 are $23.2 million, of which $3.8 million represents excess facilities and other costs and $19.4 million represents employee severances and related benefits.

We expect to incur additional costs with respect to the 2012 restructuring through the remainder of fiscal year 2013. The total cost of the 2012 restructuring is expected to be approximately $5.1 million for excess facilities and other costs and approximately $19.7 million for employee severance and related benefits. The estimated costs not yet recorded in the condensed consolidated statement of income relate to excess facilities costs, net of sublease assumptions, and employee severance-related costs as we transition away from our divested product lines (Note 6).

A summary of activity for the 2012 restructuring action during the six months ended May 31, 2013, is as follows (in thousands):



	Excess Facilities and Other Costs			Employee Severance and Related Benefits			Total
Balance, December 1, 2012	$	603		$	6,429		$	7,032
Costs incurred	1,096			3,053			4,149
Cash disbursements	(398		)	(7,286		)	(7,684		)
Asset impairment	(111		)	—			(111		)
Translation adjustments and other	(18		)	34			16
Balance, May 31, 2013	$	1,172		$	2,230		$	3,402

Cash disbursements under the 2012 restructuring are expected to be made through fiscal year 2016. The short-term portion of the restructuring reserve of $3.2 million is included in other accrued liabilities and the long-term portion of $0.2 million is included in other noncurrent liabilities on the condensed consolidated balance sheet at May 31, 2013.

2010 Restructuring

During the first and third quarters of fiscal year 2010, our management approved, committed to and initiated plans to restructure and improve efficiencies in our operations as a result of certain management and organizational changes and acquisitions. We reduced our global workforce primarily within the development, sales and administrative organizations. This workforce reduction was conducted across all geographies and also resulted in a consolidation of offices in certain locations. The total costs of the 2010 restructurings primarily relate to employee severance and excess facilities expenses. The excess facilities and other costs represent facilities costs for unused space and termination costs for automobile leases of employees included in the workforce reduction.

As part of the 2010 restructuring activities, we recorded cumulative expenses totaling $43.3 million, of which $8.0 million represents excess facilities and other costs and $35.3 million represents employee severances and related benefits. There were no charges to restructuring expense in the first six months of fiscal year 2013 related to the 2010 activities and we do not expect to incur additional expenses related to these activities.

As of November 30, 2012, we had a remaining reserve related to severance payments of $0.3 million, which is included in other accrued liabilities on the condensed consolidated balance sheets. We paid the remaining benefits during the first six months of fiscal year 2013.

- Definition

The entire disclosure for restructuring and related activities. Description of restructuring activities such as exit and disposal activities, include facts and circumstances leading to the plan, the expected plan completion date, the major types of costs associated with the plan activities, total expected costs, the accrual balance at the end of the period, and the periods over which the remaining accrual will be settled.

Income Taxes	6 Months Ended
Income Taxes	May 31, 2013
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our income tax provision for the second quarter of fiscal year 2013 and 2012 reflects our estimates of the effective tax rates expected to be applicable for the full fiscal years, adjusted for any discrete events which are recorded in the period they occur. The estimates are reevaluated each quarter based on our estimated tax expense for the full fiscal year. The research and development credit was retroactively reinstated in January 2013. As a result, in the first quarter of fiscal year 2013 we recorded a tax benefit of $0.4 million related to qualifying research and development activities for the period from January 2012 to November 2012. The Internal Revenue Service finalized its examination of our U.S. Federal income tax returns for fiscal years 2009 and 2010 during the second quarter of fiscal year 2013. In the first quarter of fiscal year 2013, we had effectively settled certain unrecognized tax benefits which had been reserved in previous periods, reducing our unrecognized tax benefits liability by $1.2 million. Our Federal income tax returns have been examined or are closed by statute for all years prior to fiscal year 2011, and we are no longer subject to audit for those periods. State taxing authorities are currently examining our income tax returns for years through fiscal year 2010. Our state income tax returns have been examined or are closed by statute for all years prior to fiscal year 2005, and we are no longer subject to audit for those periods. Tax authorities for certain non-U.S. jurisdictions are also examining returns affecting unrecognized tax benefits, none of which are material to our condensed consolidated balance sheets, cash flows or statements of income. With some exceptions, we are generally no longer subject to tax examinations in non-U.S. jurisdictions for years prior to fiscal year 2007.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

We compute basic earnings per share using the weighted average number of common shares outstanding. We compute diluted earnings per share using the weighted average number of common shares outstanding plus the effect of outstanding dilutive stock options, restricted stock units and deferred stock units, using the treasury stock method. The following table sets forth the calculation of basic and diluted earnings per share from continuing operations on an interim basis (in thousands, expect per share data):



	Three Months Ended				Six Months Ended
	May 31, 2013		May 31, 2012		May 31, 2013		May 31, 2012
Income from continuing operations	$	8,142	$	8,855	$	17,955	$	24,715
Weighted average shares outstanding	54,919		63,051		56,410		62,598
Dilutive impact from common stock equivalents	817		—		834		1,043
Diluted weighted average shares outstanding	55,736		63,051		57,244		63,641
Basic earnings per share from continuing operations	$	0.15	$	0.14	$	0.32	$	0.39
Diluted earnings per share from continuing operations	$	0.15	$	0.14	$	0.31	$	0.39

We excluded stock awards representing approximately 775,000 shares, 1,084,000 shares, 7,890,000 shares and 3,668,000 shares of common stock from the calculation of diluted earnings per share in the three and six months ended May 31, 2013 and 2012, respectively, because these awards were anti-dilutive.

Subsequent Events	6 Months Ended
Subsequent Events	May 31, 2013
Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In June 2013, we announced the adoption of a Rule 10b5-1 share repurchase plan for the purpose of repurchasing up to $100 million of our common stock as part of our previously announced repurchase authorization, which the Board of Directors increased by $10 million to $360 million. The plan will be active from July 1, 2013 until December 31, 2013 or, if earlier, upon the repurchase of $100 million of our common stock under the plan. We previously utilized a Rule 10b5-1 plan to repurchase $250 million of our common stock between October 2012 and May 2013.

Basis of Presentation (Policies)	6 Months Ended
Basis of Presentation (Policies)	May 31, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	We prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (GAAP) for complete financial statements and these unaudited financial statements should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended November 30, 2012. We made no significant changes in the application of our significant accounting policies that were disclosed in our Annual Report on Form 10-K for the fiscal year ended November 30, 2012. We have prepared the accompanying unaudited condensed consolidated financial statements on the same basis as the audited financial statements included in our Annual Report on Form 10-K, and these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of the interim periods presented. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full fiscal year. During the fourth quarter of fiscal year 2012 and the first quarter of fiscal year 2013, we completed the divestitures of the ten product lines which were not considered core product lines of our business: Actional, Artix, DataXtend, FuseSource, ObjectStore, Orbacus, Orbix, Savvion, Shadow and Sonic. The divestitures were part of the new strategic plan (the "Plan") we announced during fiscal year 2012. After the announcement of the Plan, we began reporting our results in two reportable segments: Core and non-Core. Since the non-Core segment ceased to exist during the first quarter of fiscal year 2013, after the closing of all these divestitures, we now operate as one reportable segment. In addition, the revenues and direct expenses of the product lines divested are included in discontinued operations in our condensed consolidated statements of income, including prior period amounts which have been revised to reflect the presentation. In June 2013, we entered into a definitive purchase and sale agreement to divest our Apama product line to Software AG. The target market, deployment and sales model for the Apama product line differs significantly from those of our application development platform and the divestiture allows us to focus entirely on providing leading cloud and mobile application development technologies through a single cohesive platform. The sale is expected to close in July 2013 for $44.3 million. As of May 31, 2013, we met the requirements to classify the sale of this product line as both held for sale and discontinued operations in the consolidated financial statements. The revenues and direct expenses of the Apama product line are included in discontinued operations in our consolidated statements of income, including prior period amounts which have been revised to reflect the presentation.
Recent Accounting Pronouncements	In September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-08, Intangibles – Goodwill and Other (Topic 350) – Testing Goodwill for Impairment (ASU 2011-08), to allow entities to use a qualitative approach to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If after performing the qualitative assessment an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step goodwill impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step goodwill impairment test. ASU 2011-08 is effective for us in fiscal year 2013. We adopted ASU 2011-08 during the first quarter of fiscal year 2013 for our annual impairment test, which occurs in the first quarter of our fiscal year. The adoption did not have any impact on our financial position, results of operations or cash flows. In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220) – Presentation of Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. In December 2011, the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220) – Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05 (ASU 2011-12), which defers the effective date of only those changes in ASU 2011-05 that relate to the presentation of reclassification adjustments. We adopted ASU 2011-05 in our first quarter of fiscal year 2013, and applied it retrospectively. We elected to report comprehensive income as a separate, but consecutive statement to net income. The adoption of ASU 2011-05 did not have any impact on our financial position, results of operations or cash flows. In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220) – Reporting of Amounts Reclassified out of Accumulative Other Comprehensive Income (ASU 2013-02), which replaces the presentation requirements for reclassifications out of accumulated other comprehensive income in ASU 2011-05 and ASU 2011-12. ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to present significant amounts reclassified out of accumulated other comprehensive income by respective line items of net income if the amount reclassified is required to be reclassified to net income in its entirety. We adopted ASU 2013-02 in the second quarter of fiscal year 2013 and applied it prospectively. The adoption of ASU 2013-02 did not have any impact on our financial position, results of operations or cash flows.

- Definition

Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid Investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Short-term investments, exclusive of cash equivalents, generally consist of marketable securities intended to be sold within one year (or the normal operating cycle if longer) and may include trading securities, available-for-sale securities, or held-to-maturity securities (if maturing within one year), as applicable.
