Nature Of Business And Summary Of Significant Accounting Policies	Nature of Business and Summary of Significant Accounting Policies
	The Company
	We are a global software company that simplifies the development, deployment and management of business applications on-premise or in the cloud, on any platform or device, to any data source, with enhanced performance, minimal IT complexity and low total cost of ownership. Our comprehensive portfolio of products provides leading solutions for rapid development, broad data integration and efficient data analysis. Our solutions are used across a variety of industries.
	Our products are generally sold as perpetual licenses, but certain products and business activities also use term licensing models and our Progress Pacific platform offering uses a subscription based model. More than half of our worldwide license revenue is realized through relationships with indirect channel partners, principally application partners and original equipment manufacturers (OEMs). Application partners are independent software vendors (ISVs) that develop and market applications using our technology and resell our products in conjunction with sales of their own products that incorporate our technology. OEMs are companies that embed our products into their own software products or devices.
	During fiscal years 2012 and 2013, we completed divestitures of the eleven product lines which were not considered core product lines of our business. The divestitures were part of our strategic plan announced during fiscal year 2012. The revenue and direct expenses of the product lines divested are included in discontinued operations in our consolidated statements of income, including prior period amounts which have been revised to reflect the presentation.
	Effective September 1, 2014, we began operating as three distinct business units: OpenEdge, Data Connectivity and Integration, and Application Development and Deployment, each with dedicated sales, product management and product marketing functions. As a result of these changes, we began segment reporting for our three business units beginning in the fourth fiscal quarter of 2014. The segment information for the prior periods presented has been restated to reflect the change in our reportable segments.
	We operate in North America and Latin America (the Americas); Europe, the Middle East and Africa (EMEA); and the Asia Pacific region, through local subsidiaries as well as independent distributors.
	Accounting Principles
	We prepare our consolidated financial statements and accompanying notes in conformity with accounting principles generally accepted in the United States of America (GAAP).
	Basis of Consolidation
	The consolidated financial statements include our accounts and those of our subsidiaries (all of which are wholly-owned). We eliminate all intercompany balances and transactions.
	Use of Estimates
	The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an on-going basis, management evaluates its estimates and records changes in estimates in the period in which they become known. These estimates are based on historical data and experience, as well as various other assumptions that management believes to be reasonable under the circumstances. The most significant estimates relate to the timing and amounts of revenue recognition, the realization of tax assets and estimates of tax liabilities, fair values of investments in marketable securities, intangible assets and goodwill valuations, the recognition and disclosure of contingent liabilities, the collectability of accounts receivable, and assumptions used to determine the fair value of stock-based compensation. Actual results could differ from those estimates.
	Foreign Currency Translation
	The functional currency of most of our foreign subsidiaries is the local currency in which the subsidiary operates. For foreign operations where the local currency is considered to be the functional currency, we translate assets and liabilities into U.S. dollars at the exchange rate on the balance sheet date. We translate income and expense items at average rates of exchange prevailing during each period. We accumulate translation adjustments in accumulated other comprehensive loss, a component of shareholders’ equity.
	For foreign operations where the U.S. dollar is considered to be the functional currency, we remeasure monetary assets and liabilities into U.S. dollars at the exchange rate on the balance sheet date and non-monetary assets and liabilities are remeasured into U.S. dollars at historical exchange rates. We translate income and expense items at average rates of exchange prevailing during each period. We recognize remeasurement adjustments currently as a component of foreign currency (loss) gain in the statements of income.
	Transaction gains or losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in foreign currency (loss) gain in the statements of income as incurred.
	Cash Equivalents and Investments
	Cash equivalents include short-term, highly liquid investments purchased with remaining maturities of three months or less. As of November 30, 2014, all of our cash equivalents were invested in money market funds.
	We classify investments, state and municipal bond obligations, and corporate bonds and notes, as investments available-for-sale, which are stated at fair value. Prior period investments also included auction rate securities (ARS). We include aggregate unrealized holding gains and losses, net of taxes, on available-for-sale securities as a component of accumulated other comprehensive loss in shareholders’ equity. We include realized and unrealized gains and losses on trading securities in interest income and other on the consolidated statements of income.
	We monitor our investment portfolio for impairment on a periodic basis. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other than temporary, an impairment charge is recorded and a new cost basis for the investment is established. In determining whether an other-than-temporary impairment exists, we consider the nature of the investment, the length of time and the extent to which the fair value has been less than cost, and our intent and ability to continue holding the security for a period sufficient for an expected recovery in fair value.
	During the third quarter of fiscal year 2014, we sold all our ARS for $26.2 million and realized a loss of $2.6 million, which has been recorded within interest income and other in the consolidated statements of income.
	Allowances for Doubtful Accounts and Sales Credit Memos
	We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. We establish this allowance using estimates that we make based on factors such as the composition of the accounts receivable aging, historical bad debts, changes in payment patterns, changes to customer creditworthiness and current economic trends.
	We also record an allowance for estimates of potential sales credit memos. This allowance is determined based on an analysis of historical credit memos issued and current economic trends, and is recorded as a reduction of revenue.
	A summary of activity in the allowance for doubtful accounts is as follows (in thousands):
		November 30, 2014			November 30, 2013			November 30, 2012
	Beginning balance	$	2,250		$	2,278		$	5,495

	Translation adjustments	(2		)	3			—
	Ending balance	$	946		$	903		$	746
	Concentrations of Credit Risk
	Our financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investments, derivative instruments and trade receivables. We have cash investment policies which, among other things, limit investments to investment-grade securities. We hold our cash and cash equivalents, investments and derivative instrument contracts with high quality financial institutions and we monitor the credit ratings of those institutions. We perform ongoing credit evaluations of our customers, and the risk with respect to trade receivables is further mitigated by the diversity, both by geography and by industry, of the customer base. No single customer represented more than 10% of consolidated accounts receivable or revenue in fiscal years 2014, 2013 or 2012.
	Fair Value of Financial Instruments
	The carrying amount of our cash and cash equivalents, accounts receivable and accounts payable approximates fair value due to the short-term nature of these items. We base the fair value of short-term investments on quoted market prices or other relevant information generated by market transactions involving identical or comparable assets. Previous to their sale during fiscal year 2014, the fair value of ARS was based on a valuation methodology utilizing discounted cash flow models due to the absence of quoted market prices. We measure and record derivative financial instruments at fair value. We elect fair value measurement for certain financial assets on a case-by-case basis. See Note 4 for further discussion of financial instruments that are carried at fair value on a recurring and nonrecurring basis.
	Derivative Instruments
	We record all derivatives, whether designated in hedging relationships or not, on the consolidated balance sheets at fair value. We use derivative instruments to manage exposures to fluctuations in the value of foreign currencies, which exist as part of our ongoing business operations. Certain assets and forecasted transactions are exposed to foreign currency risk. Our objective for holding derivatives is to eliminate or reduce the impact of these exposures. We periodically monitor our foreign currency exposures to enhance the overall economic effectiveness of our foreign currency hedge positions. Principal currencies hedged include the euro, British pound, Brazilian real, and Australian dollar. We do not enter into derivative instruments for speculative purposes, nor do we hold or issue any derivative instruments for trading purposes.
	We enter into certain derivative instruments that do not qualify for hedge accounting and are not designated as hedges. Although these derivatives do not qualify for hedge accounting, we believe that such instruments are closely correlated with the underlying exposure, thus managing the associated risk. The gains or losses from changes in the fair value of such derivative instruments that are not accounted for as hedges are recognized in earnings in interest income and other in the consolidated statements of income.
	Property and Equipment
	We record property and equipment at cost. We record property and equipment purchased in business combinations at fair value, which is then treated as the cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the useful lives of the assets. Useful lives by major asset class are as follows: computer equipment and software, 3 to 7 years; buildings and improvements, 5 to 39 years; and furniture and fixtures, 5 to 7 years. Repairs and maintenance costs are expensed as incurred.
	Product Development and Internal Use Software
	Expenditures for product development, other than internal use software costs, are expensed as incurred. Product development expenses primarily consist of personnel and related expenses for our product development staff, the cost of various third-party contractor fees, and allocated overhead expenses.
	Software development costs associated with internal use software are incurred in three stages of development: the preliminary project stage, the application development stage, and the post-implementation stage. Costs incurred during the preliminary project and post-implementation stages are expensed as incurred. Certain internal and external qualifying costs incurred during the application development stage are capitalized as property and equipment. Internal use software is amortized on a straight-line basis over its estimated useful life of three years, beginning when the software is ready for its intended use.
	During the years ended November 30, 2014 and 2013, there were $4.1 million and $0.8 million of internal use software development costs capitalized, respectively. During the year ended November 30, 2012, there were no internal software development costs capitalized. Amortization expense related to internal use software totaled $0.7 million during the year ended November 30, 2014 and $0 during the years ended November 30, 2013 and 2012.
	Goodwill, Intangible Assets and Long-Lived Assets
	Goodwill is the amount by which the cost of acquired net assets in a business combination exceeded the fair value of net identifiable assets on the date of purchase. We evaluate goodwill and other intangible assets with indefinite useful lives, if any, for impairment annually or on an interim basis when events and circumstances arise that indicate impairment may have occurred. During the fourth quarter of fiscal year 2014, we changed the date of our annual impairment testing for goodwill from December 15 to October 31. This change did not result in the delay, acceleration or avoidance of an impairment charge. We believe this change in accounting principle is preferable because it better aligns the timing of the annual goodwill impairment testing with our planning and budgeting process, which is a key component of the tests, and alleviates administrative burden during our year-end reporting period. The change to the goodwill testing date was applied prospectively, as retrospective application is impractical because we were unable to objectively select assumptions that would have been used in previous periods without the benefit of hindsight. We completed the required annual testing of goodwill for impairment as of both December 15, 2013 and October 31, 2014 and have determined that goodwill was not impaired at either date.
	In performing our annual assessment, we may first perform a qualitative test and if necessary, perform a quantitative test. To conduct the quantitative impairment test of goodwill, we compare the fair value of a reporting unit to its carrying value. If the reporting unit’s carrying value exceeds its fair value, we record an impairment loss to the extent that the carrying value of goodwill exceeds its implied fair value. We estimate the fair values of our reporting units using discounted cash flow models or other valuation models, such as comparative transactions and market multiples.
	We periodically review long-lived assets (primarily property and equipment) and intangible assets with finite lives (purchased technology, capitalized software and customer-related intangibles, which we amortize using the pattern in which the economic benefit will be realized or using the straight-line method if a pattern cannot be reliably determined) for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of those assets are no longer appropriate. We base each impairment test on a comparison of the undiscounted cash flows to the carrying value of the asset. If impairment is indicated, we write down the asset to its estimated fair value based on a discounted cash flow analysis. In fiscal year 2012 we recorded an impairment loss of $0.9 million related to assets no longer deployed as part of cost reduction strategies associated with our restructuring action. In fiscal year 2013, we recorded an additional $0.1 million impairment loss related to these assets. We recorded no impairment losses in fiscal year 2014.
	Comprehensive Loss
	The components of comprehensive loss include, in addition to net income, unrealized gains and losses on investments and foreign currency translation adjustments.
	Accumulated other comprehensive loss by components, net of tax (in thousands):
		Foreign Currency Translation Adjustment			Unrealized Gains (Losses) on investments			Total
	Balance, December 1, 2012	$	(8,183	)	$	(2,581	)	$	(10,764	)
	Other comprehensive income (loss) before reclassifications	(1,066		)	(209		)	(1,275		)
	Amounts reclassified from accumulated other comprehensive income (loss)	—			380			380
	Net current-period other comprehensive (loss) income	$	(1,066	)	$	171		$	(895	)
Balance, December 1, 2013	$	(9,249	)	$	(2,410	)	$	(11,659	)
Other comprehensive income (loss) before reclassifications	(4,484		)	800			(3,684		)
Amounts reclassified from accumulated other comprehensive income (loss)	—			1,617			1,617
Net current-period other comprehensive (loss) income	$	(4,484	)	$	2,417		$	(2,067	)
Balance, November 30, 2014	$	(13,733	)	$	7		$	(13,726	)
The amounts reclassified from accumulated other comprehensive income (loss) for fiscal years 2014 and 2013 relate to realized losses on available-for-sale ARS, which are recorded in interest income and other in the consolidated statements of income. The amounts reclassified are presented net of tax of $0.9 million for fiscal year 2014. The amount of tax related to the amounts reclassified during fiscal year 2013 is minimal. The tax effect on accumulated unrealized losses on investments was minimal at November 30, 2014 and $1.4 million and $1.5 million at November 30, 2013 and 2012, respectively.
Revenue Recognition
We derive our revenue primarily from software licenses and maintenance and services. Our license arrangements generally contain multiple elements, including software maintenance services, consulting services, and customer education services. We do not recognize revenue until the following four basic criteria are met: (i) persuasive evidence of an arrangement exists, (ii) our product has been shipped or, if delivered electronically, the customer has the right to access the software, (iii) the fee is fixed or determinable, and (iv) collection of the fee is probable.
Evidence of an arrangement generally consists of a contract or purchase order signed by the customer. In regard to delivery, we generally ship our software electronically and do not license our software with conditions of acceptance. If an arrangement does contain conditions of acceptance, we defer recognition of the revenue until the acceptance criteria are met or the period of acceptance has passed. Services are considered delivered as the work is performed or, in the case of maintenance, over the contractual service period. We assess whether a fee is fixed or determinable at the outset of the arrangement and consider the payment terms of the transaction, including transactions that extend beyond our customary payment terms. We do not license our software with a right of return. In assessing whether the collection of the fee is probable, we consider customer credit-worthiness, a customer’s historical payment experience, economic conditions in the customer’s industry and geographic location and general economic conditions. If we do not consider collection of a fee to be probable, we defer the revenue until the fees are collected, provided all other conditions for revenue recognition have been met.
In determining when to recognize revenue from a customer arrangement, we are often required to exercise judgment regarding the application of our accounting policies to a particular arrangement. The primary judgments used in evaluating revenue recognized in each period involve: determining whether collection is probable, assessing whether the fee is fixed or determinable, and determining the fair value of the maintenance and services elements included in multiple-element software arrangements. Such judgments can materially impact the amount of revenue that we record in a given period. While we follow specific and detailed rules and guidelines related to revenue recognition, we make and use significant management judgments and estimates in connection with the revenue recognized in any reporting period, particularly in the areas described above. If management made different estimates or judgments, material differences in the timing of the recognition of revenue could occur.
In regard to software license revenues, perpetual and term license fees are recognized as revenue when the software is delivered, no significant obligations or contingencies related to the software exist, other than maintenance, and all other revenue recognition criteria are met. We generally recognize revenue for products distributed through application partners and distributors on a sell-in basis.
Revenue from maintenance is recognized ratably over the service period. Maintenance revenue is deferred until the associated license is delivered to the customer and all other criteria for revenue recognition have been met. Revenue from other services, which are primarily consulting and customer education services, is generally recognized as the services are delivered to the customer, provided all other criteria for revenue recognition have been met.
We generally sell our software licenses with maintenance services and, in some cases, also with consulting services. For these multiple element arrangements, we allocate revenue to the delivered elements of the arrangement using the residual method, whereby revenue is allocated to the undelivered elements based on vendor specific objective evidence (or VSOE) of fair value of the undelivered elements with the remaining arrangement fee allocated to the delivered elements and recognized as revenue assuming all other revenue recognition criteria are met. For the undelivered elements, we determine VSOE of fair value to be the price charged when the undelivered element is sold separately. We determine VSOE for maintenance sold in connection with a software license based on the amount that will be separately charged for the maintenance renewal period. Substantially all license arrangements indicate the renewal rate for which customers may, at their option, renew their maintenance agreement. We determine VSOE for consulting services by reference to the amount charged for similar engagements when a software license sale is not involved. We review services sold separately on a periodic basis and update, when appropriate, our VSOE of fair value for such maintenance and services to ensure that it reflects our recent pricing experience. If VSOE of fair value for the undelivered elements cannot be established, we defer all revenue from the arrangement until the earlier of the point at which such sufficient VSOE does exist or all elements of the arrangement have been delivered, or if the only undelivered element is maintenance, then we recognize the entire fee ratably over the maintenance period. If payment of the software license fees is dependent upon the performance of consulting services or the consulting services are essential to the functionality of the licensed software, then we recognize both the software license and consulting fees using the completed contract method.
Sales taxes collected from customers and remitted to government authorities are excluded from revenue.
With the introduction of Progress Pacific in fiscal year 2013, we have also begun offering products via a platform-as-a-service (PaaS) model, which is a subscription based model. Subscription revenue derived from these agreements is generally recognized on a straight-line basis over the subscription term, provided persuasive evidence of an arrangement exists, access to our software has been granted to the customer, the fee for the subscription is fixed or determinable, and collection of the subscription fee is probable.
Deferred revenue generally results from contractual billings for which revenue has not been recognized and consists of the unearned portion of license, maintenance, and services fees. Deferred revenue expected to be recognized as revenue more than one year subsequent to the balance sheet date is included in long-term liabilities in the consolidated balance sheets.
Advertising Costs
Advertising costs are expensed as incurred and were $1.8 million, $1.6 million and $1.5 million in fiscal years 2014, 2013 and 2012, respectively.
Warranty Costs
We make periodic provisions for expected warranty costs. Historically, warranty costs have been insignificant.
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, the Black-Scholes option valuation model, or the Monte Carlo Simulation valuation model. The Black-Scholes and Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. We recognize stock-based compensation expense related to options and restricted stock units 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. We recognize stock-based compensation expense related to performance stock units and our employee stock purchase plan using an accelerated attribution method.
Acquisition-Related Costs
Acquisition-related costs are expensed as incurred and include those costs incurred as a result of a business combination. These costs consist of professional service fees, including third-party legal and valuation-related fees, as well as retention fees, including earn-out payments treated as compensation expense. We incurred $5.9 million of acquisition-related costs, which are included in acquisition-related expenses in our consolidated statement of operations for the fiscal year ended November 30, 2014.
Restructuring Charges
Our restructuring charges are comprised primarily of costs related to property abandonment, including future lease commitments, net of any sublease income, and associated leasehold improvements; and employee termination costs related to headcount reductions. We recognize and measure restructuring liabilities initially at fair value when the liability is incurred.
Income Taxes
We provide for deferred income taxes resulting from temporary differences between financial and taxable income. We record valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized.
We recognize and measure uncertain tax positions taken or expected to be taken in a tax return utilizing a two-step approach. We first determine if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is that we measure the tax benefit as the largest amount that is more likely than not to be realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in our provision for income taxes on our consolidated statements of income.
Recent Accounting Pronouncements
In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15). ASU 2014-15 provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. ASU 2014-15 applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The adoption of ASU 2014-15 is not expected to have a material impact on our financial position, results of operations or cash flows.
In June 2014, the FASB issued Accounting Standards Update No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASU 2014-12). ASU 2014-12 brings consistency to the accounting for share-based payment awards that require a specific performance target to be achieved in order for employees to become eligible to vest in the awards. This guidance is effective for all entities for reporting periods (including interim periods) beginning after December 15, 2015. Early adoption is permitted. In addition, all entities will have the option of applying the guidance either prospectively (i.e., only to awards granted or modified on or after the effective date of the ASU) or retrospectively. We are currently evaluating the effect that implementation of this update will have on our consolidated financial position and results of operations upon adoption.
In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016; early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. This update could impact the timing and amounts of revenue recognized. We are currently evaluating the effect that implementation of this update will have on our consolidated financial position and results of operations upon adoption.
In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASU 2013-11). ASU 2013-11 clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance is effective on a prospective basis for fiscal years and interim reporting periods within those years, beginning after December 15, 2013. The adoption of ASU 2013-11 is not expected to have a material impact on our financial position, results of operations or cash flows.
In March 2013, the FASB issued Accounting Standards Update No. 2013-05, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (ASU 2013-05). ASU 2013-05 provides guidance on releasing cumulative translation adjustments when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or a business within a foreign entity. ASU 2013-05 is effective on a prospective basis for fiscal years and interim reporting periods within those years, beginning after December 15, 2013. Early adoption is permitted. The adoption of ASU 2013-05 is not expected to have a material impact on our financial position, results of operations or cash flows.

	During the third quarter of fiscal year 2014, we sold all of our remaining ARS for $26.2 million and received the proceeds during the quarter. The previously recorded unrealized losses associated with our ARS have been adjusted based on the sale prices and recorded as a realized loss of $2.6 million during fiscal year 2014 within interest income and other in the consolidated statement of operations.
	During prior periods in which we held ARS, we evaluated the risks related to the structure, collateral and liquidity of the investment and forecasted the probability of issuer default, auction failure and a successful auction at par or a redemption at par for each future auction period. The weighted average cash flow for each period was then discounted back to present value for each security. Based on this methodology, we determined that the fair value of our ARS investments was $24.8 million at November 30, 2013. The temporary impairment recorded in accumulated other comprehensive loss to reduce the value of our available-for-sale ARS investments was $4.0 million at November 30, 2013. As we determined that these investments lacked short-term liquidity as of November 30, 2013, they were classified as long-term investments on the consolidated balance sheets at November 30, 2013.
	During the fourth quarter of fiscal year 2013, the exit bankruptcy plan for an issuer of one of our ARS, which was in default and on whose behalf the underlying bond insurer was making interest payments, was approved by a federal bankruptcy judge in federal court. The exit bankruptcy plan included a settlement provision with the holders of the ARS, which were given the option to receive 80% of the par value of their holdings, but renounce their claim with the bond issuer, or receive 65% of the par value of their holdings and retain their insurance rights. We accepted the 80% settlement offer and as a result we adjusted the fair value of this ARS to the amount of the settlement as of November 30, 2013. The previously recorded unrealized loss associated with this ARS has been recorded as a realized loss in fiscal year 2013 due to the settlement, which we received in December 2013. The realized loss of $0.4 million is recorded in interest income and other on the statement of operations for the fiscal year ended November 30, 2013. As this investment no longer lacked short-term liquidity, it was classified as a short-term investment on our consolidated balance sheet at November 30, 2013.

	We generally use forward contracts that are not designated as hedging instruments to hedge economically the impact of the variability in exchange rates on accounts receivable 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 or other current liabilities on the consolidated balance sheets at the end of each reporting period and expire within 90 days. In fiscal years 2014, 2013 and 2012, realized and unrealized (losses) gains of $(1.5) million, $1.1 million, and $(0.2) million, respectively, from our forward contracts were recognized in foreign currency loss in the consolidated statements of income.

	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 as of November 30, 2013, which consists of ARS, was primarily an income approach, where the expected weighted average future cash flows were discounted back to present value for each asset. The significant unobservable inputs used in the fair value measurement of our ARS were 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 were such that a change in the assumptions used for the probability of principal return prior to maturity was 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 was somewhat independent and based upon the ARS' specific underlying assets and published recovery rate studies.
	The following table provides additional quantitative information about the unobservable inputs used in our Level 3 asset valuations as of November 30, 2013:
		Valuation Technique		Unobservable Input	Range (Weighted Average)
	Auction rate securities	Discounted cash flow		Probability of earning the maximum rate until maturity	0.2% - 10.7% (1.9%)

				Probability of default	4.2% - 24.5% (11.5%)
				Liquidity risk premium	4.00%
				Recovery rate in default	50% - 70% (56.5%)

	As discussed in Note 2, during the third quarter of fiscal year 2014, we sold all of our remaining ARS for $26.2 million and received the proceeds during the quarter. The previously recorded unrealized losses associated with our ARS have been adjusted based on the sales prices and recorded as a realized loss of $2.6 million for fiscal year 2014 within interest income and other in the consolidated statement of operations.
	During the fourth quarter of fiscal year 2013, we accepted an 80% settlement offer on one of our ARS, and as a result we adjusted the fair value of this ARS to the amount of the settlement as of November 30, 2013. We transferred the ARS to a Level 2 fair value measurement, as the value at the end of fiscal year 2013 was based on observable inputs. We recorded a realized loss in interest income and other in the consolidated statement of income. We received the settlement in December 2013.
	We have also classified contingent consideration related to the Rollbase, Inc. (Rollbase) and Modulus LLC (Modulus) acquisitions, which occurred in the second quarter of fiscal years 2013 and 2014, respectively, 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 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 November 30, 2014 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%. The key assumptions as of November 30, 2014 related to the contingent consideration for the acquisition of Modulus used in the model are probabilities in excess of 75% that the milestones associated with the contingent consideration will be achieved and a discount rate of 33.0%. A decrease in the probabilities of achievement could result in a significant decrease to the estimated fair value of the contingent consideration liability.
	The following table reflects the activity for our contingent consideration obligations measured at fair value using Level 3 inputs for each period presented

	Translation adjustments	(140		)	(245		)
	Balance, end of year	$	232,836		$	224,286
	The additions to goodwill during fiscal year 2014 are related to the acquisitions of Modulus and BravePoint. The addition to goodwill during fiscal year 2013 is related to the acquisition of Rollbase. The disposal is related to the sale of the Apama product line.
	During the fourth quarter of 2014, we began operating as three distinct business units: OpenEdge, Data Connectivity and Integration, and Application Development and Deployment, each with dedicated sales, product management and product marketing functions. As a result of these changes, we began segment reporting for our three business units beginning in the fourth fiscal quarter of 2014. During the fourth quarter of fiscal year 2014, we reassigned goodwill to the new reporting units based on the relative fair values of the reporting units. This resulted in goodwill of $212.2 million being assigned to our OpenEdge reporting unit, $19.0 million being assigned to our Data Connectivity and Integration reporting unit, and $1.5 million being assigned to our Application Development and Deployment reporting unit.
	We assess the impairment of goodwill on an annual basis and whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. During the fourth quarter of fiscal year 2014, we changed the date of our annual impairment testing for goodwill from December 15 to October 31. We believe this change in accounting principle is preferable because it better aligns the timing of the annual goodwill impairment testing with our planning and budgeting process, which is a key component of the tests, and alleviates administrative burden during our year-end reporting period.
	During fiscal year 2014, we tested goodwill for impairment as of December 15, 2013, our previous annual testing date, and on October 31, 2014, our new annual testing date.
	At the time of our December 15, 2013 annual test, we operated as a single operating segment with one reporting unit and consequently we evaluated goodwill for impairment based on an evaluation of the fair value of the Company as a whole. We performed our qualitative assessment and concluded that it was not more likely than not ("MLTN") that the fair value of our operating segment was less than its carrying value.
	In connection with the reassignment of our goodwill to our new reporting units during the fourth quarter of fiscal year 2014, we performed goodwill impairment tests on both our old and new reporting units to ensure that no impairment existed prior to the reassignment of goodwill or resulted after the reassignment of goodwill. Prior to the reassignment of goodwill from our single operating segment with one reporting unit, we performed a qualitative assessment and concluded that it was not MLTN that the fair value of the reporting unit was less than its carrying value. After the reassignment of goodwill to our three reporting units, we compared the fair value of those reporting units to their carrying values under a Step 1 approach. The OpenEdge and Data Connectivity and Integration reporting units had fair values that significantly exceeded their carrying values, and as such, Step 2 of the impairment test was not required.
	For the Application Development and Deployment reporting unit, the Step 1 test indicated that the fair value of this reporting unit was below its carrying value. We performed Step 2 of the impairment test which compared the implied fair value of the Application Development and Deployment reporting unit's goodwill to its carrying value. The implied fair value of goodwill is derived by performing a hypothetical purchase price allocation for the reporting unit as of the measurement date and allocating the reporting unit’s estimated fair value to its assets and liabilities. The residual amount from performing this allocation represents the implied fair value of goodwill. To the extent this amount is below the carrying value of goodwill, an impairment charge is recorded. As a result of completing Step 2, the Application Development and Deployment reporting unit's implied fair value of goodwill exceeded the carrying value of goodwill of $1.5 million, resulting in no impairment charge.
	We recorded no goodwill impairment losses in fiscal years 2014, 2013 or 2012.

Discontinued Operations and Disposal Groups [Abstract]
Divestitures	Divestitures
	During fiscal year 2012, we announced that we would divest all product lines which were 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 the third quarter of fiscal year 2013, we divested our Apama product line to Software AG. The purchase price was $44.3 million.
	Revenues and direct expenses of the divested product lines have been reclassified as discontinued operations for fiscal years 2012 and 2013. The fiscal year 2012 results include revenues and direct expenses of all divested product lines, 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 the product lines which had not been divested prior to the start of fiscal year 2013.
	Apama
	In the third quarter of fiscal year 2013, we divested our Apama product line to Software AG for a purchase price of $44.3 million. Of the total consideration, $4.5 million was held in escrow to secure indemnification claims, if any, for up to 18 months. As of November 30, 2014, the escrow is included in other current assets on the consolidated balance sheet. The escrow was released to us in January 2015.
	In connection with the sale, we also entered into a three year distributor license agreement with Software AG for $0.7 million for one of our DataDirect products. The distributor license agreement does not constitute direct cash flows or significant continuing involvement of the Apama product line, and thus does not preclude us from discontinued operations treatment.
	Revenues and direct expenses of the Apama product line have been reclassified as discontinued operations for fiscal years 2012 and 2013. The components included in discontinued operations on the consolidated statements of income are as follows (in thousands):

	In the first quarter of fiscal year 2013, we divested our Artix, Orbacus and Orbix product lines to a subsidiary of Micro Focus International plc (Micro Focus) for total consideration of $15.0 million.
	Revenues and direct expenses of these product lines have been reclassified as discontinued operations for fiscal years 2012 and 2013. The components included in discontinued operations on the consolidated statements of income are as follows (in thousands):

	Income from discontinued operations, net	$	4,764		$	2,441
	In the fourth quarter of fiscal year 2012, we recorded an impairment loss of $8.6 million related to the assets held for sale of the Artix, Orbacus and Orbix product lines 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 and was included in income (loss) from discontinued operations.
	The gain on sale of the Artix, Orbacus and Orbix product lines was calculated as follows (in thousands):
	Purchase price	$	15,000

	Gain on sale, net of tax	$	2,009
	In the first quarter of fiscal year 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 was $1.0 million. During the fourth quarter of fiscal year 2013, the matter was resolved and our actual indemnification obligation was $30,000.
	The gain recorded in fiscal year 2013 was the result of differences in our estimation of net assets to be sold at closing as of November 30, 2012 versus the actual value of the net assets sold at closing.
	Actional, DataXtend, ObjectStore, Savvion and Sonic
	In the first quarter of fiscal year 2013, we divested our Actional, DataXtend, ObjectStore, Savvion and Sonic product lines to the investment arm of Trilogy Enterprises (Trilogy) for total consideration of $60.5 million.

In the fourth quarter of fiscal year 2012, we divested our Shadow product line to Rocket Software, Inc for total consideration of $33.0 million. Of the total consideration, $3.3 million was held in escrow to secure indemnification claims, if any, for 15 months. We received the $3.3 million during the first quarter of fiscal year 2014.
Revenues and direct expenses of the Shadow product line have been reclassified as discontinued operations for fiscal years 2012 and 2013. The components included in discontinued operations on the consolidated statements of income are as follows (in thousands):

Business Combinations	Business Combinations
	BravePoint Acquisition
	On October 1, 2014, we acquired 100% of the capital stock of BravePoint, Inc. (BravePoint) from Chesapeake Utilities Corporation in exchange for $12.0 million in cash. BravePoint is based in Norcross, Georgia and is a leading provider of consulting, training and application development services designed to increase customers' profitability and competitiveness through the use of technology. This acquisition significantly extends our services capabilities and enhances our ability to quickly enable our partners and customers to take greater advantage of new technologies.  The acquisition was accounted for as a business combination, and accordingly, the results of operations of BravePoint are included in our operating results as part of the OpenEdge business unit from the date of acquisition. We paid the purchase price in cash from available funds.
	The allocation of the purchase price is as follows (in thousands):
		Total			Life
	Net working capital	$	2,222
	Property and equipment	735
	Other assets	16
	Purchased technology	5,920			7 Years
	Customer-related and other	850			7 Years
	Goodwill	2,257
	Net assets acquired	$	12,000
	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 $2.3 million of goodwill. The goodwill is deductible for tax purposes. The allocation of the purchase price was completed in the fourth quarter of fiscal year 2014 upon the finalization of our valuation of identifiable intangible assets.
	We incurred approximately $0.2 million of acquisition-related costs, which are included in acquisition-related expenses in our consolidated statement of operations for the twelve months ended November 30, 2014. We have not disclosed the amount of revenues and earnings of BravePoint since acquisition, nor pro forma financial information, as those amounts are not significant to our consolidated financial statements.
	Modulus Acquisition
	On May 13, 2014, we acquired 100% of the membership interests in Modulus LLC (Modulus), a privately held platform-as-a-service (PaaS) provider based in Cincinnati, Ohio, for $15.0 million. The purchase consideration consisted of $12.5 million in cash paid and $2.5 million of contingent consideration, expected to be paid out over a two year period, if earned. The fair value of the contingent consideration was estimated to be $1.5 million at the date of acquisition; as such, the fair value of the purchase consideration allocated to the assets acquired totaled $14.0 million. Modulus provides a PaaS for easily hosting, deploying, scaling and monitoring data-intensive, real-time applications using powerful, rapidly growing Node.js and MongoDB technologies. The purpose of the acquisition is to capitalize on the expected market growth of the core technologies that Modulus supports and drive new revenue through the Pacific platform. The acquisition was accounted for as a business combination, and accordingly, the results of operations of Modulus are included in our operating results as part of our Application Development and Deployment business unit from the date of acquisition. We paid the purchase price in cash from available funds.
	The allocation of the purchase price is as follows (in thousands):
		Total			Life
	Net working capital	$	7
	Purchased technology	7,320			7 Years
	Customer-related and other	190			7 Years
	Goodwill	6,433
	Net assets acquired	$	13,950
	The purchase consideration includes contingent earn-out provisions payable by the Company based on the achievement of certain milestones. We 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 based on an internal rate of return analysis using the probability-weighted cash flows. The key assumptions as of the acquisition date related to the contingent consideration are probabilities in excess of 75% that the milestones associated with the contingent consideration will be achieved and a discount rate of 33.0%.
	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 $6.4 million of goodwill. The goodwill is deductible for tax purposes. The allocation of the purchase price was completed in the third quarter of fiscal year 2014 upon the finalization of our valuation of identifiable intangible assets.
	We incurred approximately $0.3 million of acquisition-related costs, which are included in acquisition-related expenses in our consolidated statement of operations for the twelve months ended November 30, 2014. We have not disclosed the amount of revenues and earnings of Modulus since acquisition, nor pro forma financial information, as those amounts are not significant to our condensed consolidated financial statements.
	Rollbase Acquisition
	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 development software technology that allows the rapid design, development and deployment of on-demand business applications. 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 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 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 $5.3 million, are compensation arrangements and we have been accruing the maximum payouts ratably over the two year performance period, as we believe it is probable that the criteria will be met. During the second and third quarters of fiscal year 2014, we paid the former Rollbase owners the contingent consideration related to milestones reached as of the one year anniversary of the acquisition closing date in the amount of $2.7 million. We have incurred $2.8 million and $1.9 million of expense related to the contingent earn-out provisions for the fiscal years ended November 30, 2014 and November 30, 2013, respectively. These amounts are recorded as acquisition-related expenses in our consolidated statement of operations.
	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 allocation of the purchase price was completed in the third quarter of fiscal year 2013 upon the finalization of our valuation of identifiable intangible assets and acquired deferred tax liabilities. The weighted average amortization period for the acquired intangible assets, which is comprised of purchased technology and customer relationships, is 5 and 1 years, respectively.
	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.

Line of Credit Facility [Abstract]
Line of Credit	Line of Credit
	On August 15, 2011, we entered into a credit agreement (the "Credit Agreement") for an unsecured credit facility with J.P. Morgan and other lenders that matures on August 15, 2016, at which time all amounts outstanding must be repaid. The credit facility provides for a revolving line of credit in the amount of $150.0 million, with a sublimit for the issuance of standby letters of credit in a face amount up to $25.0 million and swing line loans up to $20.0 million. The credit facility also permits us to increase the revolving line of credit by up to an additional $75.0 million subject to receiving further commitments from lenders and certain other conditions.
	Revolving loans accrue interest at a per annum rate based on our choice of either (i) the LIBOR rate plus a margin ranging from 1.25% to 1.75% or (ii) the base rate plus a margin ranging from 0.25% to 0.75%, both depending on our consolidated leverage ratio. The base rate is defined as the highest of (i) the administrative agent’s prime rate (ii) the federal funds rate plus 0.50%, and (iii) the LIBOR rate for a one month interest period plus a margin equal to 1.00%. A quarterly commitment fee on the undrawn portion of the revolving credit facility is required, at a per annum rate ranging from 0.25% to 0.35%, depending on our consolidated leverage ratio. The loan origination fee and issuance costs incurred upon consummation of the Credit Agreement are being amortized through interest income and other in the consolidated statement of income using the effective interest rate method, over the five year term of the facility. Other customary fees and letter of credit fees may be charged and will be expensed as they are incurred.
	Accrued interest on the loans is payable quarterly in arrears with respect to base rate loans and at the end of each interest rate period (or at each three month interval in the case of loans with interest periods greater than three months) with respect to LIBOR rate loans. We may prepay, terminate or reduce the loan commitments in whole or in part at any time, without premium or penalty, subject to certain conditions and reimbursement of certain costs in the case of LIBOR rate loans. The Credit Agreement contains customary affirmative and negative covenants, including a requirement to maintain a balance of at least $100.0 million in cash and cash equivalents while making restricted equity-related payments (e.g. cash dividend distributions or share repurchases of our common stock). We are also required to maintain compliance with a consolidated leverage ratio of no greater than 3.00 to 1.00 and a consolidated interest coverage ratio of at least 3.00 to 1.00. As of November 30, 2014, there were no amounts outstanding under the revolving line and $0.7 million of letters of credit outstanding.
	On December 2, 2014, in connection with entering into the new credit facility described in Note 19, we terminated the Credit Agreement dated August 15, 2011. As indicated above, the Credit Agreement was to mature on August 15, 2016. Loans under the Credit Agreement could be paid before maturity in whole or in part at our option without penalty or premium. There were no revolving loans and $0.7 million of letters of credit outstanding at the time of the termination of the Credit Agreement, which letters of credit were incorporated into the new credit facility.

	Leasing Arrangements
	We lease certain facilities and equipment under non-cancelable operating lease arrangements. Future minimum rental payments under these leases are as follows at November 30, 2014 (in thousands):
	2015	$	5,733
	2016	3,620
	2017	2,111
	2018	1,170
	2019	991
	Thereafter	1,626
	Total	$	15,251
	Our operating lease arrangements are subject to customary renewal and base rental fee escalation clauses. Total rent expense, net of sublease income which is insignificant, under operating lease arrangements was approximately $6.5 million, $6.5 million and $8.7 million in fiscal years 2014, 2013 and 2012, respectively.
	Guarantees and Indemnification Obligations
	We include standard intellectual property indemnification provisions in our licensing agreements in the ordinary course of business. Pursuant to our product license agreements, we will indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally business partners or customers, in connection with certain patent, copyright or other intellectual property infringement claims by third parties with respect to our products. Other agreements with our customers provide indemnification for claims relating to property damage or personal injury resulting from the performance of services by us or our subcontractors. Historically, our costs to defend lawsuits or settle claims relating to such indemnity agreements have been insignificant. Accordingly, the estimated fair value of these indemnification provisions is immaterial.
	Legal Proceedings
	We are subject to various legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. While the outcome of these claims cannot be predicted with certainty, management does not believe that the outcome of any of these other legal matters will have a material effect on our financial position, results of operations or cash flows.

Equity [Abstract]
Shareholders' Equity	Shareholders’ Equity
	Preferred Stock
	Our Board of Directors is authorized to establish one or more series of preferred stock and to fix and determine the number and conditions of preferred shares, including dividend rates, redemption and/or conversion provisions, if any, preferences and voting rights. As of November 30, 2014, there was no preferred stock issued or outstanding.
	Common Stock
	We have 200,000,000 shares of authorized common stock, $0.01 par value per share, of which 50,676,769 were issued and outstanding at November 30, 2014.
	There were 74,900 deferred stock units (DSUs) outstanding at November 30, 2014. Each DSU represents one share of our common stock and all DSU grants have been made to non-employee members of our Board of Directors. The DSUs granted prior to fiscal year 2011 were fully vested on the date of grant and do not have voting rights and can only be converted into common stock when the recipient ceases being a member of the Board of Directors. There were 21,700 DSUs granted in fiscal year 2011, of which 18,235 were vested as of November 30, 2014.
	Common Stock Repurchases
	In January 2014, our Board of Directors authorized a $100.0 million share repurchase program. The timing and amount of any shares repurchased will be determined by management based on its evaluation of market conditions and other factors, and the Board of Directors may choose to suspend, expand or discontinue the repurchase program at any time. In fiscal year 2014, we repurchased and retired 2.3 million shares of our common stock for $52.6 million.
	During the second quarter of fiscal year 2012, our Board of Directors authorized a $350.0 million return of capital to shareholders in the form of a share repurchase through fiscal year 2013. In July 2013, the Board increased the authorization by $10.0 million to $360.0 million. In fiscal years 2013 and 2012, we repurchased and retired 11,579,000 shares and 4,494,000 shares, respectively, of our common stock for $269.5 million and $88.4 million, respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation
	We currently have one shareholder-approved stock plan from which we can issue stock-based awards, which was approved by our shareholders in fiscal year 2008 (2008 Plan). The 2008 Plan replaced the 1992 Incentive and Nonqualified Stock Option Plan, the 1994 Stock Incentive Plan and the 1997 Stock Incentive Plan (collectively, the “Previous Plans”). The Previous Plans solely exist to satisfy outstanding options previously granted under those plans. The 2008 Plan permits the granting of stock awards to officers, members of the Board of Directors, employees and consultants. Awards under the 2008 Plan may include nonqualified stock options, incentive stock options, grants of conditioned or restricted stock, unrestricted grants of stock, grants of stock contingent upon the attainment of performance goals, deferred stock units and stock appreciation rights. A total of 47,010,000 shares are issuable under these plans, of which 7,840,978 shares were available for grant as of November 30, 2014.
	We have adopted two stock plans for which the approval of shareholders was not required: the 2002 Nonqualified Stock Plan (2002 Plan) and the 2004 Inducement Stock Plan (2004 Plan). The 2002 Plan permits the granting of stock awards to non-executive officer employees and consultants. Executive officers and members of the Board of Directors are not eligible for awards under the 2002 Plan. Awards under the 2002 Plan may include nonqualified stock options, grants of conditioned or restricted stock, unrestricted grants of stock, grants of stock contingent upon the attainment of performance goals and stock appreciation rights. A total of 9,750,000 shares are issuable under the 2002 Plan, of which 840,058 shares were available for grant as of November 30, 2014.
	The 2004 Plan is reserved for persons to whom we may issue securities as an inducement to become employed by us pursuant to the rules and regulations of the NASDAQ Stock Market. Awards under the 2004 Plan may include nonqualified stock options, grants of conditioned or restricted stock, unrestricted grants of stock, grants of stock contingent upon the attainment of performance goals and stock appreciation rights. A total of 1,500,000 shares are issuable under the 2004 Plan, of which 583,021 shares were available for grant as of November 30, 2014.
	Under all of our plans, the options granted prior to fiscal year 2005 generally vest over five years and have terms of ten years. The options granted from fiscal year 2005 through fiscal year 2010 generally vest over five years and have terms of seven years, and the options granted since fiscal year 2011 vest over four years and have a term of seven years.
	A summary of stock option activity under all the plans is as follows:
		Shares		Weighted Average				Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value (1)
		(in thousands)		Exercise Price				(in years)		(in thousands)
	Options outstanding, December 1, 2013	1,989		$	20.43
	Granted	8		21.8
	Exercised (2)	(736	)	18.81
	Canceled	(46	)	26.61
	Options outstanding, November 30, 2014	1,215		$	21.19			2.57		$	6,880
	Exercisable, November 30, 2014	1,146		$	21.09			2.5		$	6,598
	Vested or expected to vest, November 30, 2014	1,215		$	21.19			2.57		$	6,880
	-1	The aggregate intrinsic value was calculated based on the difference between the closing price of our stock on November 30, 2014 of $25.79 and the exercise prices for all in-the-money options outstanding.
	-2	Includes 46,000 options included in a stock-swap, which allowed optionees to pay the exercise price by surrendering shares already owned. The net shares of common stock resulting from option exercises is 690,000 as reflected in the statement of shareholders' equity.
	A summary of restricted stock units activity is as follows (in thousands, except per share data):
		Number of Shares		Weighted Average Grant Date Fair Value
	Restricted stock units outstanding, December 1, 2013	1,117		$	22.67
	Granted	1,484		22.28
	Issued	(866	)	23.29
	Canceled	(246	)	20.79
	Restricted stock units outstanding, November 30, 2014	1,489		$	22.24
	Each restricted stock unit represents one share of common stock. The restricted stock units generally vest semi-annually over a three year period.
	The fair value of outright stock awards, restricted stock awards, restricted stock units and DSUs is equal to the closing price of our common stock on the date of grant.
	In addition, during the first quarter of fiscal year 2014, we granted performance-based restricted stock units that include a three-year market condition. In order to estimate the fair value of such awards, we used a Monte Carlo Simulation valuation model.
	The 1991 Employee Stock Purchase Plan (ESPP) permits eligible employees to purchase up to an aggregate of 8,650,000 shares of our common stock through accumulated payroll deductions. The ESPP has a 27 month offering period comprised of nine three month purchase periods. The purchase price of the stock is equal to 85% of the lesser of the market value of such shares at the beginning of a 27 month offering period or the end of each three month segment within such offering period. If the market price at any of the nine purchase periods is less than the market price on the first date of the 27 month offering period, subsequent to the purchase, the offering period is canceled and the employee is entered into a new 27 month offering period with the then current market price as the new base price. We issued 203,000 shares, 281,000 shares and 376,000 shares with weighted average purchase prices of $17.84, $15.28 and $15.04 per share, respectively, in fiscal years 2014, 2013 and 2012, respectively. At November 30, 2014, approximately 727,000 shares were available and reserved for issuance under the ESPP.
	We estimated the fair value of stock options and ESPP awards granted in fiscal years 2014, 2013 and 2012 on the measurement dates using the Black-Scholes option valuation model with the following weighted average assumptions:
		Fiscal Year Ended
		November 30, 2014		November 30, 2013			November 30, 2012
	Stock options:
	Expected volatility	28.4	%	31.9	%		30	%
	Risk-free interest rate	1.6	%	0.7	%		0.8	%
	Expected life (in years)	4.8		4.8			4.8
	Expected dividend yield	—		—			—
	Employee stock purchase plan:
	Expected volatility	25.1	%	31.8	%		34.1	%
	Risk-free interest rate	0.3	%	0.2	%		0.2	%
	Expected life (in years)	1.6		1.5			1.5
	Expected dividend yield	—		—			—
	For each stock option award, the expected life in years is based on historical exercise patterns and post-vesting termination behavior. Expected volatility is based on historical volatility of our stock, and the risk-free interest rate is based on the U.S. Treasury yield curve for the period that is commensurate with the expected life at the time of grant. We currently do not pay cash dividends on our common stock and do not anticipate doing so for the foreseeable future.  Accordingly, our expected dividend yield is zero.
	For each ESPP award, the expected life in years is based on the period of time between the beginning of the offering period and the date of purchase, plus an additional holding period of three months.  Expected volatility is based on historical volatility of the our stock, and the risk-free interest rate is based on the U.S. Treasury yield curve in effect at each purchase period.
	Based on the above assumptions, the weighted average estimated fair value of stock options granted in fiscal years 2014, 2013 and 2012 was $5.95, $6.08 and $5.66 per share, respectively. We amortize the estimated fair value of stock options to expense over the vesting period using the straight-line method. The weighted average estimated fair value for shares issued under our ESPP in fiscal years 2014, 2013 and 2012 was $6.93, $6.88 and $6.53 per share, respectively. We amortize the estimated fair value of shares issued under the ESPP to expense over the vesting period using a graded vesting model.
	Other reasonable assumptions about these factors could provide different estimates of fair value. Future changes in stock price volatility, life of options, interest rates and dividend practices, if any, may require changes in our assumptions, which could materially affect the calculation of fair value.
	Total unrecognized stock-based compensation expense, net of expected forfeitures, related to unvested stock options and unvested restricted stock awards amounted to $17.3 million at November 30, 2014. These costs are expected to be recognized over a weighted average period of 1.7 years.
	The following additional activity occurred under our plans (in thousands):

Separation and Divestiture Arrangements
During fiscal year 2012, the employment of three of our executives terminated, including our former Chief Financial Officer, Charles F. Wagner, Jr. 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 $1.8 million, of which $0.9 million was recorded as general and administrative expense and $0.9 million was recorded as sales and marketing expense, in the consolidated statement of income.
During fiscal year 2012, we entered into transition agreements with certain employees in connection with the divestitures of certain of our product lines. As part of the transition agreements, the employees were entitled to accelerated vesting of stock-based awards if the employees remained employees of the company through the date their product line was divested. We recognized additional stock-based compensation of $1.3 million in the consolidated statement of income as a result of these agreements.
During 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 were entitled to accelerated vesting of certain stock-based awards upon the completion of the divestiture. All employees associated with the Apama product line were also entitled to accelerated vesting of certain stock-based awards upon the completion of the divestiture. Due to the accelerated vesting, we recognized additional stock-based compensation of $1.4 million.
During fiscal year 2014, we entered into separation agreements with two executives which entitled them to accelerated vesting of certain stock-based awards. Due to the separation and accelerated vesting, we recognized additional stock-based compensation expense of $1.2 million, of which $0.7 million was recorded as sales and marketing expense and $0.5 million was recorded as general and administrative expense, in the consolidated statement of income.

	2014 Restructuring
	During the third quarter of fiscal year 2014, our management approved, committed to and initiated plans to make strategic changes to our organization to provide greater focus and agility in the delivery of next generation application development, deployment and integration solutions. Effective September 1, 2014, we began to operate as three distinct business units: OpenEdge, Data Connectivity and Integration, and Application Development and Deployment, each with dedicated sales, product management and product marketing functions. In connection with the new organizational structure, we no longer have a global head of sales, as well as certain other positions within the sales and administrative organizations. The organizational changes will not result in the closing of any of our facilities.
	As part of the 2014 restructuring, for the twelve months ended November 30, 2014, we incurred expenses of $1.7 million, which are related to employee costs, including severance, health benefits, and outplacement services, but excluding stock-based compensation. The expenses are recorded as restructuring expenses in the consolidated statements of income. We do not expect to incur additional material costs with respect to the 2014 restructuring.
	A summary of activity for the 2014 restructuring action is as follows (in thousands):

	Cash disbursements for expenses incurred to date under the 2014 restructuring are expected to be made during fiscal year 2015. As a result, the $1.2 million is included in other accrued liabilities on the consolidated balance sheet at November 30, 2014.
	2013 Restructuring
	During the third quarter of fiscal year 2013, our management approved, committed to and initiated plans to restructure and improve efficiencies in our operations as a result of the sale of the Apama product line and the divestitures completed during the fourth quarter of fiscal year 2012 and the first quarter of fiscal year 2013. We reduced our global workforce primarily within the administrative and sales organizations. This workforce reduction was conducted across all geographies and also resulted in the closing of certain facilities.
	Restructuring expenses relate to employee costs, including severance, health benefits, outplacement services and transition divestiture arrangements, but excluding stock-based compensation, and facilities costs, which 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 2013 restructuring, we incurred $0.4 million of expenses in the fiscal year 2014. The expenses are recorded as restructuring expenses in the consolidated statements of income. We do not expect to incur additional material costs with respect to the 2013 restructuring.

	In the second quarter of fiscal 2012, as part of the Plan, 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 divested our non-Core product lines. Our restructuring actions include both our cost reduction efforts and qualifying costs associated with our divestitures.
	As part of the 2012 restructuring, we incurred $0.2 million of expenses in the fiscal year 2014. The expenses are recorded as restructuring expenses in the consolidated statements of income. We do not expect to incur additional material costs for the 2012 restructuring.

	Total	$	12,020			$	28,733
	The valuation allowance primarily applies to net operating loss carryforwards and unutilized tax credits in jurisdictions or under conditions where realization is not assured. The $3.3 million decrease in the valuation allowance during fiscal year 2014 relates to foreign net operating loss carryforwards expiring unutilized. The short-term portion of deferred tax liabilities of $0.2 million is included in other current liabilities on the consolidated balance sheet at November 30, 2013.
	At November 30, 2014, we have net operating loss carryforwards of $59.1 million expiring on various dates through 2030 and $2.3 million that may be carried forward indefinitely. At November 30, 2014, we have tax credit carryforwards of approximately $8.6 million expiring on various dates through 2029 and $1.9 million that may be carried forward indefinitely.
	It is our policy to indefinitely reinvest the earnings of our non-U.S. subsidiaries unless the earnings can be repatriated in a manner that is substantially tax free or a manner that generates a tax benefit. We have not provided for U.S. income taxes on the undistributed earnings of non-U.S. subsidiaries, which totaled $18.6 million as of November 30, 2014, as these earnings have been indefinitely reinvested. Any additional taxes that might be payable upon repatriation of our foreign earnings would not be significant.
	The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in a multitude of jurisdictions across our global operations. We recognize and record potential tax liabilities for anticipated tax audit issues in various tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes will be due. We adjust these reserves in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in income tax benefits being recognized in the period when we determine the liabilities are no longer necessary.
	A reconciliation of the balance of our unrecognized tax benefits is as follows (in thousands):
		Fiscal Year Ended
		30-Nov-14				30-Nov-13				30-Nov-12
	Balance, beginning of year	$	1,022			$	2,192			$	2,631
	Tax positions related to current year	849				189				79
	Settlements with tax authorities	—				(1,176		)		—
	Lapses due to expiration of the statute of limitations	(160		)		(183		)		(518		)
Balance, end of year	$	1,711			$	1,022			$	2,192
We recognize interest and penalties related to uncertain tax positions as a component of our provision for income taxes. In fiscal years 2014, 2013, and 2012 there was a minimal amount of estimated interest and penalties recorded in the provision for income taxes. We have accrued $0.2 million and $0.2 million of estimated interest and penalties at November 30, 2014 and 2013, respectively. We do not expect any significant changes to the amount of unrecognized tax benefits in the next twelve months.
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 fiscal year 2011 through fiscal year 2013. Our state income tax returns have been examined or are closed by statute for all years prior to fiscal year 2010, 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 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 2009.

Segment Reporting [Abstract]
Business Segments and International Operations	Business Segments and International Operations
	Operating segments are components of an enterprise that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and assess performance. Our chief operating decision maker is our Chief Executive Officer.
	Effective September 1, 2014, we began operating as three distinct business units: OpenEdge, Data Connectivity and Integration, and Application Development and Deployment, each with dedicated sales, product management and product marketing functions. As a result of these changes, we have begun segment reporting for our three business units beginning in the fourth fiscal quarter of 2014. The segment information for the prior periods presented has been restated to reflect the change in our reportable segments.
	We do not manage our assets or capital expenditures by segment or assign other income (expense) and income taxes to segments. We manage and report such items on a consolidated company basis.
	The following table provides revenue and contribution margin from our reportable segments and reconciles to the consolidated income from continuing operations before income taxes:

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events
	On December 2, 2014, we acquired 100% of the outstanding securities of Telerik AD (Telerik) for an aggregate sum of $262.5 million. We funded the purchase price from a combination of existing cash resources and a $150 million term loan described below. In addition, approximately $11.0 million of the purchase price is payable to Telerik’s founders and certain other key employees in restricted stock units, subject to a vesting schedule and continued employment. Telerik is a leading provider of application development tools which allow developers to create compelling user experiences across cloud, web, mobile and desktop applications. As a result of the timing of the transaction, the initial accounting for the business combination was incomplete through the date our consolidated financial statements were issued. Results of operations for Telerik will be included in our consolidated financial statements as part of the Application Development and Deployment business unit from the date of acquisition.
	On December 2, 2014, we entered into a Credit Agreement (the Credit Agreement) with each of the lenders party thereto (the Lenders), JPMorgan Chase Bank, N.A., as Administrative Agent, Wells Fargo Bank, N.A. and Citizens Bank, N.A., as Syndication Agents, Bank of America, N.A., Citibank, N.A. and Silicon Valley Bank, as Documentation Agents, and J.P. Morgan Securities LLC, as Sole Bookrunner and Sole Lead Arranger, providing for a $150 million secured term loan and a $150 million secured revolving credit facility, which may be made available in U.S. Dollars and certain other currencies. The revolving credit facility may be increased by up to an additional $75 million if the existing or additional lenders are willing to make such increased commitments. This new credit facility replaces our existing unsecured revolving credit facility dated August 15, 2011.
	The term loan was used to partially fund our acquisition of Telerik, as described above. The revolving credit facility has sublimits for swing line loans up to $25.0 million and for the issuance of standby letters of credit in a face amount up to $25.0 million. We expect to use the revolving credit facility for general corporate purposes, including acquisitions of other businesses, and may also use it for working capital.
	Interest rates for the term loan and revolving credit facility are determined at our option and would range from 1.50% to 2.25% above the Eurodollar rate for Eurodollar-based borrowings or would range from 0.50% to 1.25% above the defined base rate for base rate borrowings, in each case based upon our leverage ratio. Additionally, we may borrow certain foreign currencies at rates set in the same range above the respective London interbank offered interest rates for those currencies, based on our leverage ratio. A quarterly commitment fee on the undrawn portion of the revolving credit facility is required, ranging from 0.25% to 0.40% per annum, based upon our leverage ratio. At closing of the term loan and revolving credit facility, the applicable interest rate and commitment fee would be at the second lowest rate in each range.
	The credit facility matures on December 2, 2019, when all amounts outstanding will be due and payable in full. The revolving credit facility does not require amortization of principal. The term loan requires repayment of principal at the end of each fiscal quarter, beginning with the fiscal quarter ending February 28, 2015. The first eight payments are in the principal amount of $1.875 million each, the following eight payments are in the principal amount of $3.75 million each, the following three payments are in the principal amount of $5.625 million each, and the last payment is of the remaining principal amount. Any amounts outstanding under the term loan thereafter would be due on the maturity date. The term loan may be prepaid before maturity in whole or in part at our option without penalty or premium.
	Revolving loans may be borrowed, repaid and reborrowed until December 2, 2019, at which time all amounts outstanding must be repaid. Accrued interest on the loans is payable quarterly in arrears with respect to base rate loans and at the end of each interest rate period (or at each three month interval in the case of loans with interest periods greater than three months) with respect to LIBOR rate loans. We may prepay the loans or terminate or reduce the commitments in whole or in part at any time, without premium or penalty, subject to certain conditions and reimbursement of certain costs in the case of LIBOR rate loans.
	We are the sole borrower under the credit facility. Our obligations under the Credit Agreement are guaranteed by each of our material domestic subsidiaries and are secured by substantially all of our assets and such material domestic subsidiaries, as well as 100% of the capital stock of our domestic subsidiaries and 65% of the capital stock of our first-tier foreign subsidiaries, in each case, subject to certain exceptions as described in the Credit Agreement. Future material domestic subsidiaries will be required to guaranty our obligations under the Credit Agreement, and to grant security interests in substantially all of their assets to secure such obligations. The Credit Agreement generally prohibits, with certain exceptions, any other liens on our assets, subject to certain exceptions as described in the Credit Agreement.

Nature Of Business And Summary Of Significant Accounting Policies (Policies)	12 Months Ended
	Nov. 30, 2014
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Consolidation	Basis of Consolidation
	The consolidated financial statements include our accounts and those of our subsidiaries (all of which are wholly-owned). We eliminate all intercompany balances and transactions.
Use of Estimates	Use of Estimates
	The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an on-going basis, management evaluates its estimates and records changes in estimates in the period in which they become known. These estimates are based on historical data and experience, as well as various other assumptions that management believes to be reasonable under the circumstances. The most significant estimates relate to the timing and amounts of revenue recognition, the realization of tax assets and estimates of tax liabilities, fair values of investments in marketable securities, intangible assets and goodwill valuations, the recognition and disclosure of contingent liabilities, the collectability of accounts receivable, and assumptions used to determine the fair value of stock-based compensation. Actual results could differ from those estimates.
Foreign Currency Translation	Foreign Currency Translation
	The functional currency of most of our foreign subsidiaries is the local currency in which the subsidiary operates. For foreign operations where the local currency is considered to be the functional currency, we translate assets and liabilities into U.S. dollars at the exchange rate on the balance sheet date. We translate income and expense items at average rates of exchange prevailing during each period. We accumulate translation adjustments in accumulated other comprehensive loss, a component of shareholders’ equity.
	For foreign operations where the U.S. dollar is considered to be the functional currency, we remeasure monetary assets and liabilities into U.S. dollars at the exchange rate on the balance sheet date and non-monetary assets and liabilities are remeasured into U.S. dollars at historical exchange rates. We translate income and expense items at average rates of exchange prevailing during each period. We recognize remeasurement adjustments currently as a component of foreign currency (loss) gain in the statements of income.
	Transaction gains or losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in foreign currency (loss) gain in the statements of income as incurred.
Cash Equivalents and Investments	Cash Equivalents and Investments
	Cash equivalents include short-term, highly liquid investments purchased with remaining maturities of three months or less. As of November 30, 2014, all of our cash equivalents were invested in money market funds.
	We classify investments, state and municipal bond obligations, and corporate bonds and notes, as investments available-for-sale, which are stated at fair value. Prior period investments also included auction rate securities (ARS). We include aggregate unrealized holding gains and losses, net of taxes, on available-for-sale securities as a component of accumulated other comprehensive loss in shareholders’ equity. We include realized and unrealized gains and losses on trading securities in interest income and other on the consolidated statements of income.
	We monitor our investment portfolio for impairment on a periodic basis. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other than temporary, an impairment charge is recorded and a new cost basis for the investment is established. In determining whether an other-than-temporary impairment exists, we consider the nature of the investment, the length of time and the extent to which the fair value has been less than cost, and our intent and ability to continue holding the security for a period sufficient for an expected recovery in fair value.
	During the third quarter of fiscal year 2014, we sold all our ARS for $26.2 million and realized a loss of $2.6 million, which has been recorded within interest income and other in the consolidated statements of income.
Allowance for Doubtful Accounts	Allowances for Doubtful Accounts and Sales Credit Memos
	We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. We establish this allowance using estimates that we make based on factors such as the composition of the accounts receivable aging, historical bad debts, changes in payment patterns, changes to customer creditworthiness and current economic trends.
	We also record an allowance for estimates of potential sales credit memos. This allowance is determined based on an analysis of historical credit memos issued and current economic trends, and is recorded as a reduction of revenue.
Concentrations of Credit Risk	Concentrations of Credit Risk
	Our financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investments, derivative instruments and trade receivables. We have cash investment policies which, among other things, limit investments to investment-grade securities. We hold our cash and cash equivalents, investments and derivative instrument contracts with high quality financial institutions and we monitor the credit ratings of those institutions. We perform ongoing credit evaluations of our customers, and the risk with respect to trade receivables is further mitigated by the diversity, both by geography and by industry, of the customer base.
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	The carrying amount of our cash and cash equivalents, accounts receivable and accounts payable approximates fair value due to the short-term nature of these items. We base the fair value of short-term investments on quoted market prices or other relevant information generated by market transactions involving identical or comparable assets. Previous to their sale during fiscal year 2014, the fair value of ARS was based on a valuation methodology utilizing discounted cash flow models due to the absence of quoted market prices. We measure and record derivative financial instruments at fair value. We elect fair value measurement for certain financial assets on a case-by-case basis. See Note 4 for further discussion of financial instruments that are carried at fair value on a recurring and nonrecurring basis.
Derivative Instruments	Derivative Instruments
	We record all derivatives, whether designated in hedging relationships or not, on the consolidated balance sheets at fair value. We use derivative instruments to manage exposures to fluctuations in the value of foreign currencies, which exist as part of our ongoing business operations. Certain assets and forecasted transactions are exposed to foreign currency risk. Our objective for holding derivatives is to eliminate or reduce the impact of these exposures. We periodically monitor our foreign currency exposures to enhance the overall economic effectiveness of our foreign currency hedge positions. Principal currencies hedged include the euro, British pound, Brazilian real, and Australian dollar. We do not enter into derivative instruments for speculative purposes, nor do we hold or issue any derivative instruments for trading purposes.
	We enter into certain derivative instruments that do not qualify for hedge accounting and are not designated as hedges. Although these derivatives do not qualify for hedge accounting, we believe that such instruments are closely correlated with the underlying exposure, thus managing the associated risk. The gains or losses from changes in the fair value of such derivative instruments that are not accounted for as hedges are recognized in earnings in interest income and other in the consolidated statements of income.
Property and Equipment	Property and Equipment
	We record property and equipment at cost. We record property and equipment purchased in business combinations at fair value, which is then treated as the cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the useful lives of the assets. Useful lives by major asset class are as follows: computer equipment and software, 3 to 7 years; buildings and improvements, 5 to 39 years; and furniture and fixtures, 5 to 7 years. Repairs and maintenance costs are expensed as incurred.
Product Development Costs	Product Development and Internal Use Software
	Expenditures for product development, other than internal use software costs, are expensed as incurred. Product development expenses primarily consist of personnel and related expenses for our product development staff, the cost of various third-party contractor fees, and allocated overhead expenses.
	Software development costs associated with internal use software are incurred in three stages of development: the preliminary project stage, the application development stage, and the post-implementation stage. Costs incurred during the preliminary project and post-implementation stages are expensed as incurred. Certain internal and external qualifying costs incurred during the application development stage are capitalized as property and equipment. Internal use software is amortized on a straight-line basis over its estimated useful life of three years, beginning when the software is ready for its intended use.
Goodwill, Intangible Assets and Long-Lived Assets	Goodwill, Intangible Assets and Long-Lived Assets
	Goodwill is the amount by which the cost of acquired net assets in a business combination exceeded the fair value of net identifiable assets on the date of purchase. We evaluate goodwill and other intangible assets with indefinite useful lives, if any, for impairment annually or on an interim basis when events and circumstances arise that indicate impairment may have occurred. During the fourth quarter of fiscal year 2014, we changed the date of our annual impairment testing for goodwill from December 15 to October 31. This change did not result in the delay, acceleration or avoidance of an impairment charge. We believe this change in accounting principle is preferable because it better aligns the timing of the annual goodwill impairment testing with our planning and budgeting process, which is a key component of the tests, and alleviates administrative burden during our year-end reporting period. The change to the goodwill testing date was applied prospectively, as retrospective application is impractical because we were unable to objectively select assumptions that would have been used in previous periods without the benefit of hindsight. We completed the required annual testing of goodwill for impairment as of both December 15, 2013 and October 31, 2014 and have determined that goodwill was not impaired at either date.
	In performing our annual assessment, we may first perform a qualitative test and if necessary, perform a quantitative test. To conduct the quantitative impairment test of goodwill, we compare the fair value of a reporting unit to its carrying value. If the reporting unit’s carrying value exceeds its fair value, we record an impairment loss to the extent that the carrying value of goodwill exceeds its implied fair value. We estimate the fair values of our reporting units using discounted cash flow models or other valuation models, such as comparative transactions and market multiples.
	We periodically review long-lived assets (primarily property and equipment) and intangible assets with finite lives (purchased technology, capitalized software and customer-related intangibles, which we amortize using the pattern in which the economic benefit will be realized or using the straight-line method if a pattern cannot be reliably determined) for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of those assets are no longer appropriate. We base each impairment test on a comparison of the undiscounted cash flows to the carrying value of the asset. If impairment is indicated, we write down the asset to its estimated fair value based on a discounted cash flow analysis.
Comprehensive Loss	Comprehensive Loss
	The components of comprehensive loss include, in addition to net income, unrealized gains and losses on investments and foreign currency translation adjustments.
Revenue Recognition	Revenue Recognition
	We derive our revenue primarily from software licenses and maintenance and services. Our license arrangements generally contain multiple elements, including software maintenance services, consulting services, and customer education services. We do not recognize revenue until the following four basic criteria are met: (i) persuasive evidence of an arrangement exists, (ii) our product has been shipped or, if delivered electronically, the customer has the right to access the software, (iii) the fee is fixed or determinable, and (iv) collection of the fee is probable.
	Evidence of an arrangement generally consists of a contract or purchase order signed by the customer. In regard to delivery, we generally ship our software electronically and do not license our software with conditions of acceptance. If an arrangement does contain conditions of acceptance, we defer recognition of the revenue until the acceptance criteria are met or the period of acceptance has passed. Services are considered delivered as the work is performed or, in the case of maintenance, over the contractual service period. We assess whether a fee is fixed or determinable at the outset of the arrangement and consider the payment terms of the transaction, including transactions that extend beyond our customary payment terms. We do not license our software with a right of return. In assessing whether the collection of the fee is probable, we consider customer credit-worthiness, a customer’s historical payment experience, economic conditions in the customer’s industry and geographic location and general economic conditions. If we do not consider collection of a fee to be probable, we defer the revenue until the fees are collected, provided all other conditions for revenue recognition have been met.
	In determining when to recognize revenue from a customer arrangement, we are often required to exercise judgment regarding the application of our accounting policies to a particular arrangement. The primary judgments used in evaluating revenue recognized in each period involve: determining whether collection is probable, assessing whether the fee is fixed or determinable, and determining the fair value of the maintenance and services elements included in multiple-element software arrangements. Such judgments can materially impact the amount of revenue that we record in a given period. While we follow specific and detailed rules and guidelines related to revenue recognition, we make and use significant management judgments and estimates in connection with the revenue recognized in any reporting period, particularly in the areas described above. If management made different estimates or judgments, material differences in the timing of the recognition of revenue could occur.
	In regard to software license revenues, perpetual and term license fees are recognized as revenue when the software is delivered, no significant obligations or contingencies related to the software exist, other than maintenance, and all other revenue recognition criteria are met. We generally recognize revenue for products distributed through application partners and distributors on a sell-in basis.
	Revenue from maintenance is recognized ratably over the service period. Maintenance revenue is deferred until the associated license is delivered to the customer and all other criteria for revenue recognition have been met. Revenue from other services, which are primarily consulting and customer education services, is generally recognized as the services are delivered to the customer, provided all other criteria for revenue recognition have been met.
	We generally sell our software licenses with maintenance services and, in some cases, also with consulting services. For these multiple element arrangements, we allocate revenue to the delivered elements of the arrangement using the residual method, whereby revenue is allocated to the undelivered elements based on vendor specific objective evidence (or VSOE) of fair value of the undelivered elements with the remaining arrangement fee allocated to the delivered elements and recognized as revenue assuming all other revenue recognition criteria are met. For the undelivered elements, we determine VSOE of fair value to be the price charged when the undelivered element is sold separately. We determine VSOE for maintenance sold in connection with a software license based on the amount that will be separately charged for the maintenance renewal period. Substantially all license arrangements indicate the renewal rate for which customers may, at their option, renew their maintenance agreement. We determine VSOE for consulting services by reference to the amount charged for similar engagements when a software license sale is not involved. We review services sold separately on a periodic basis and update, when appropriate, our VSOE of fair value for such maintenance and services to ensure that it reflects our recent pricing experience. If VSOE of fair value for the undelivered elements cannot be established, we defer all revenue from the arrangement until the earlier of the point at which such sufficient VSOE does exist or all elements of the arrangement have been delivered, or if the only undelivered element is maintenance, then we recognize the entire fee ratably over the maintenance period. If payment of the software license fees is dependent upon the performance of consulting services or the consulting services are essential to the functionality of the licensed software, then we recognize both the software license and consulting fees using the completed contract method.
	Sales taxes collected from customers and remitted to government authorities are excluded from revenue.
	With the introduction of Progress Pacific in fiscal year 2013, we have also begun offering products via a platform-as-a-service (PaaS) model, which is a subscription based model. Subscription revenue derived from these agreements is generally recognized on a straight-line basis over the subscription term, provided persuasive evidence of an arrangement exists, access to our software has been granted to the customer, the fee for the subscription is fixed or determinable, and collection of the subscription fee is probable.
	Deferred revenue generally results from contractual billings for which revenue has not been recognized and consists of the unearned portion of license, maintenance, and services fees. Deferred revenue expected to be recognized as revenue more than one year subsequent to the balance sheet date is included in long-term liabilities in the consolidated balance sheets.
Advertising Costs	Advertising Costs
	Advertising costs are expensed as incurred and were $1.8 million, $1.6 million and $1.5 million in fiscal years 2014, 2013 and 2012, respectively.
Warranty Costs	Warranty Costs
	We make periodic provisions for expected warranty costs. Historically, warranty costs have been insignificant.
Stock-Based Compensation	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, the Black-Scholes option valuation model, or the Monte Carlo Simulation valuation model. The Black-Scholes and Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. We recognize stock-based compensation expense related to options and restricted stock units 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.
Acquisition-Related Costs	Acquisition-Related Costs
	Acquisition-related costs are expensed as incurred and include those costs incurred as a result of a business combination. These costs consist of professional service fees, including third-party legal and valuation-related fees, as well as retention fees, including earn-out payments treated as compensation expense.
Restructuring Charges	Restructuring Charges
	Our restructuring charges are comprised primarily of costs related to property abandonment, including future lease commitments, net of any sublease income, and associated leasehold improvements; and employee termination costs related to headcount reductions. We recognize and measure restructuring liabilities initially at fair value when the liability is incurred.
Income Taxes	Income Taxes
	We provide for deferred income taxes resulting from temporary differences between financial and taxable income. We record valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized.
	We recognize and measure uncertain tax positions taken or expected to be taken in a tax return utilizing a two-step approach. We first determine if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is that we measure the tax benefit as the largest amount that is more likely than not to be realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in our provision for income taxes on our consolidated statements of income.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15). ASU 2014-15 provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. ASU 2014-15 applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The adoption of ASU 2014-15 is not expected to have a material impact on our financial position, results of operations or cash flows.
	In June 2014, the FASB issued Accounting Standards Update No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASU 2014-12). ASU 2014-12 brings consistency to the accounting for share-based payment awards that require a specific performance target to be achieved in order for employees to become eligible to vest in the awards. This guidance is effective for all entities for reporting periods (including interim periods) beginning after December 15, 2015. Early adoption is permitted. In addition, all entities will have the option of applying the guidance either prospectively (i.e., only to awards granted or modified on or after the effective date of the ASU) or retrospectively. We are currently evaluating the effect that implementation of this update will have on our consolidated financial position and results of operations upon adoption.
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016; early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. This update could impact the timing and amounts of revenue recognized. We are currently evaluating the effect that implementation of this update will have on our consolidated financial position and results of operations upon adoption.
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASU 2013-11). ASU 2013-11 clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance is effective on a prospective basis for fiscal years and interim reporting periods within those years, beginning after December 15, 2013. The adoption of ASU 2013-11 is not expected to have a material impact on our financial position, results of operations or cash flows.
	In March 2013, the FASB issued Accounting Standards Update No. 2013-05, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (ASU 2013-05). ASU 2013-05 provides guidance on releasing cumulative translation adjustments when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or a business within a foreign entity. ASU 2013-05 is effective on a prospective basis for fiscal years and interim reporting periods within those years, beginning after December 15, 2013. Early adoption is permitted. The adoption of ASU 2013-05 is not expected to have a material impact on our financial position, results of operations or cash flows.
