| Summary Of Significant Accounting Policies | B. Summary of Significant Accounting Policies Foreign Currency Translation For our non-U.S. operations where the functional currency is the local currency, we translate assets and liabilities at exchange rates in effect at the balance sheet date and record translation adjustments in stockholders’ equity. For our non-U.S. operations where the U.S. dollar is the functional currency, we remeasure monetary assets and liabilities using exchange rates in effect at the balance sheet date and nonmonetary assets and liabilities at historical rates and record resulting exchange gains or losses in foreign currency net losses in the Consolidated Statements of Operations. We translate income statement amounts at average rates for the period. Transaction gains and losses are recorded in foreign currency net losses in the Consolidated Statements of Operations. Revenue Recognition Our sources of revenue include: (1) subscription, (2) support, (3) perpetual license and (4) professional services. Through 2018, we recorded revenues for software related deliverables in accordance with the guidance provided by ASC 985-605, Software-Revenue Recognition and revenues for non-software deliverables in accordance with ASC 605-25 , Revenue Recognition, Multiple-Element Arrangements. Under those standards, revenue is recorded when the following criteria are met: (1) persuasive evidence of an arrangement exists, (2) delivery has occurred (generally, FOB shipping point or electronic distribution), (3) the fee is fixed or determinable, and (4) collection is probable. We exercise judgment and use estimates in connection with determining the amounts of software license and services revenues to be recognized in each accounting period. Our primary judgments involve the following: • determining whether collection is probable; • assessing whether the fee is fixed or determinable; • determining whether service arrangements, including modifications and customization of the underlying software, are not essential to the functionality of the licensed software and thus would result in the revenue for license and service elements of an agreement being recorded separately; and • determining the fair value of services and support elements included in multiple-element arrangements, which is the basis for allocating and deferring revenue for such services and support. Our software is distributed primarily through our direct sales force. In addition, we have an indirect distribution channel through alliances with resellers. Revenue arrangements with resellers are generally recognized on a sell-through basis; that is, when we deliver the product to the end-user customer. We record consideration given to a reseller as a reduction of revenue to the extent we have recorded revenue from the reseller. We do not offer contractual rights of return, stock balancing, or price protection to our resellers, and actual product returns from them have been insignificant to date. As a result, we do not maintain reserves for reseller product returns. At the time of each sale transaction, we must make an assessment of the collectability of the amount due from the customer. Revenue is only recognized at that time if management deems that collection is probable. In making this assessment, we consider customer credit-worthiness and historical payment experience. At that same time, we assess whether fees are fixed or determinable and free of contingencies or significant uncertainties. In assessing whether the fee is fixed or determinable, we consider the payment terms of the transaction, including transactions with payment terms that extend beyond our customary payment terms, and our collection experience in similar transactions without making concessions, among other factors. We have periodically provided financing to credit-worthy customers with payment terms up to 24 months. If the fee is determined not to be fixed or determinable, revenue is recognized only as payments become due from the customer, provided that all other revenue recognition criteria are met. Our software license arrangements generally do not include customer acceptance provisions. However, if an arrangement includes an acceptance provision, we record revenue only upon the earlier of (1) receipt of written acceptance from the customer or (2) expiration of the acceptance period. Generally, our contracts are accounted for individually. However, when contracts are closely interrelated and dependent on each other, it may be necessary to account for two or more contracts as one to reflect the substance of the group of contracts. Subscription Subscription revenue includes revenue from two primary sources: (1) subscription-based licenses, and (2) cloud services. Subscription-based licenses include the right for a customer to use our licenses on-premise and receive related support for a specified term and revenue is recognized ratably over the term of the arrangement since we do not have vendor-specific objective evidence (“VSOE”) of fair value for our coterminous support. When sold in arrangements with other elements, VSOE of fair value is established for the subscription-based licenses through the use of a substantive renewal clause within the customer contract for a combined annual fee that includes the term-based license and related support. Cloud services revenue (which in 2018, 2017 and 2016 represented less than 5% of our total revenue) includes fees for hosting and application management of customers’ perpetual or subscription-based licenses (hosting services) and fees for Software as a Service (SaaS) arrangements. When hosting services are sold as part of a multi-element transaction, revenue is allocated to hosting services based on VSOE, and recognized ratably over the contractual term beginning on the commencement dates of each contract, which is the date the services are made available to the customer. VSOE is established for hosting services either through a substantive stated renewal option or stated contractual overage rates, as these rates represent the value the customer is willing to pay on a standalone basis. We also offer cloud services under SaaS arrangements whereby customers access our software in the cloud. Under SaaS arrangements, customers cannot take possession of the software. Cloud services include set-up fees, which are recognized ratably over the contract term or the expected customer life, whichever is longer. Support Support contracts generally include rights to unspecified upgrades (when and if available), telephone and internet-based support, updates and bug fixes. Support revenue is recognized ratably over the term of the support contract on a straight-line basis. Perpetual License Under perpetual license arrangements, we generally recognize license revenue up front upon shipment to the customer. We use the residual method to recognize revenue from perpetual license software arrangements that include one or more elements to be delivered at a future date when evidence of the fair value of all undelivered elements exists, and the elements of the arrangement qualify for separate accounting as described below. Under the residual method, the fair value of the undelivered elements (i.e., support and services) based on our VSOE of fair value is deferred and the remaining portion of the total arrangement fee is allocated to the delivered elements (i.e., perpetual software license). If evidence of the fair value of one or more of the undelivered elements does not exist, all revenues are deferred and recognized when delivery of all of those elements has occurred or when fair values can be established. We determine VSOE of the fair value of services and support revenue based upon our recent pricing for those elements when sold separately. For certain transactions, VSOE is determined based on a substantive renewal clause within a customer contract. Our current pricing practices are influenced primarily by product type, purchase volume, sales channel and customer location. We review services and support sold separately on a periodic basis and update, when appropriate, our VSOE of fair value for such elements to ensure that it reflects our recent pricing experience. Professional Services Our software arrangements often include implementation, consulting and training services that are sold under consulting engagement contracts or as part of the software license arrangement. When we determine that such services are not essential to the functionality of the licensed software, we record revenue separately for the license and service elements of these arrangements, provided that appropriate evidence of fair value exists for the undelivered services (i.e. VSOE of fair value). We consider various factors in assessing whether a service is not essential to the functionality of the software, including if the services may be provided by independent third parties experienced in providing such services (i.e. consulting and implementation) in coordination with dedicated customer personnel, and whether the services result in significant modification or customization of the software’s functionality. When professional services qualify for separate accounting, professional services revenues under time and materials billing arrangements are recognized as the services are performed. Professional services revenues under fixed-priced contracts are generally recognized as the services are performed using a proportionate performance model with hours or costs as the input method of attribution. When we provide professional services that are considered essential to the functionality of the software, the arrangement does not qualify for separate accounting of the license and service elements, and the license revenue is recognized together with the consulting services using the percentage-of-completion method of contract accounting. Under such arrangements, consideration is recognized as the services are performed as measured by an observable input. In these circumstances, we separate license revenue from service revenue for income statement presentation by allocating VSOE of fair value of the consulting services as service revenue, and the residual portion as license revenue. Under the percentage-of-completion method, we estimate the stage of completion of contracts with fixed or “not to exceed” fees based on hours or costs incurred to date as compared with estimated total project hours or costs at completion. Adjustments to estimates to complete are made in the periods in which facts resulting in a change become known. When total cost estimates exceed revenues, we accrue for the estimated losses when identified. The use of the proportionate performance and percentage-of-completion methods of accounting require significant judgment relative to estimating total contract costs or hours (hours being a proxy for costs), including assumptions relative to the length of time to complete the project, the nature and complexity of the work to be performed and anticipated changes in salaries and other costs. Reimbursements of out-of-pocket expenditures incurred in connection with providing consulting services are included in professional services revenue, with the offsetting expense recorded in cost of professional services revenue. Training services include on-site and classroom training. Training revenues are recognized as the related training services are provided. Deferred Revenue Billed deferred revenue primarily relates to software subscription and support agreements billed to customers for which the services have not yet been provided. The liability associated with performing these services is included in deferred revenue and, if not yet paid, the related customer receivable is included in other current assets. Billed but uncollected support and subscription-related amounts included in other current assets at September 30, 2018 and 2017 were $153.6 million and $160.9 million , respectively. Deferred revenue consisted of the following: September 30, 2018 2017 (in thousands) Deferred subscription revenue $ 288,012 $ 193,376 Deferred support revenue 196,684 256,999 Deferred perpetual license revenue 1,475 1,773 Deferred professional services revenue 13,272 6,759 Total deferred revenue $ 499,443 $ 458,907 Cash Equivalents Our cash equivalents are invested in money market accounts and time deposits of financial institutions. We have established guidelines relative to credit ratings, diversification and maturities that are intended to maintain safety and liquidity. Cash equivalents include highly liquid investments with maturity periods of three months or less when purchased. Marketable Securities Our investment portfolio consists of certificates of deposit, commercial paper, corporate notes/bonds and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. All unrealized losses are due to changes in market interest rates, bond yields and/or credit ratings. We review our investments to identify and evaluate investments that have an indication of possible impairment. We concluded that, at September 30, 2018 , the unrealized losses were temporary. Cost Method Investments We generally account for non-marketable equity investments under the cost method. We monitor non-marketable equity investments for events that could indicate that the investments are impaired, such as deterioration in the investee's financial condition and business forecasts, and lower valuations in recent or proposed financings. For an other-than-temporary impairment in the investment, we record a charge to other expense for the difference between the estimated fair value and the carrying value. The carrying value of our non-marketable equity investments are recorded in noncurrent assets and totaled $1.7 million and $0.7 million as of September 30, 2018 and 2017 , respectively. In 2017, we sold a cost method investment in a private company for $13.7 million for a gain of approximately $3.7 million . Concentration of Credit Risk and Fair Value of Financial Instruments The amounts reflected in the Consolidated Balance Sheets for cash and cash equivalents, accounts receivable and accounts payable approximate their fair value due to their short maturities. Financial instruments that potentially subject us to concentration of credit risk consist primarily of investments, trade accounts receivable and foreign currency derivative instruments. Our cash, cash equivalents, and foreign currency derivatives are placed with financial institutions with high credit standings. Our credit risk for derivatives is also mitigated due to the short-term nature of the contracts. Our customer base consists of large numbers of geographically diverse customers dispersed across many industries. No individual customer comprised more than 10% of our trade accounts receivable as of September 30, 2018 or 2017 or comprised more than 10% of our revenue for the years ended September 30, 2018 , 2017 or 2016 . Fair Value Measurements Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. Generally accepted accounting principles prescribe a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs that may be used to measure fair value: • Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or • Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Allowance for Doubtful Accounts We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. In determining the adequacy of the allowance for doubtful accounts, management specifically analyzes individual accounts receivable, historical bad debts, customer concentrations, customer credit-worthiness, current economic conditions, and accounts receivable aging trends. Our allowance for doubtful accounts on trade accounts receivable was $0.6 million as of September 30, 2018 , $1.1 million as of September 30, 2017 , $1.0 million as of September 30, 2016 and $1.0 million as of September 30, 2015 . Uncollectible trade accounts receivable written-off, net of recoveries, were $1.0 million , $1.5 million and $0.3 million in 2018 , 2017 and 2016 , respectively. Bad debt expense was $0.5 million , $1.5 million and $0.3 million in 2018 , 2017 and 2016 , respectively, and is included in general and administrative expenses in the accompanying Consolidated Statements of Operations. Allowance for Sales Credits We record an allowance for sales credits that is established based on the evaluation of historical credits and is recorded as a reduction in accounts receivable and revenue. As of September 30, 2018 , the allowance for sale credits was $2.0 million . Derivatives Generally accepted accounting principles require all derivatives, whether designated in a hedging relationship or not, to be recorded on the balance sheet at fair value. Our earnings and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. Our most significant foreign currency exposures relate to Western European countries, Japan, China and Canada. Our foreign currency risk management strategy is principally designed to mitigate the future potential financial impact of changes in the U.S. dollar value of anticipated transactions and balances denominated in foreign currency, resulting from changes in foreign currency exchange rates. We enter into derivative transactions, specifically foreign currency forward contracts, to manage the exposures to foreign currency exchange risk to reduce earnings volatility. We do not enter into derivatives transactions for trading or speculative purposes. For a description of our non-designated hedge and cash flow hedge activities see Note P. Derivative Financial Instruments . Non-Designated Hedges We hedge our net foreign currency monetary assets and liabilities primarily resulting from foreign currency denominated receivables and payables with foreign exchange forward contracts to reduce the risk that our earnings and cash flows will be adversely affected by changes in foreign currency exchange rates. These contracts have maturities of up to approximately three months. Generally, we do not designate these foreign currency forward contracts as hedges for accounting purposes and changes in the fair value of these instruments are recognized immediately in earnings. Gains or losses on the underlying foreign-denominated balance are offset by the loss or gain on the forward contract and are included in foreign currency losses, net. Cash Flow Hedges Our foreign exchange risk management program objective is to identify foreign exchange exposures and implement appropriate hedging strategies to minimize earnings fluctuations resulting from foreign exchange rate movements. We designate certain foreign exchange forward contracts as cash flow hedges of Euro, Yen and SEK denominated intercompany forecast revenue transactions (supported by third party sales). All foreign exchange forward contracts are carried at fair value on the Consolidated Balance Sheets and the maximum duration of foreign exchange forward contracts is 14 months. Cash flow hedge relationships are designated at inception, and effectiveness is assessed prospectively and retrospectively using regression analysis on a monthly basis. As the forward contracts are highly effective in offsetting changes to future cash flows on the hedged transactions, we record the effective portion of changes in these cash flow hedges in accumulated other comprehensive income and subsequently reclassify into earnings in the same period during which the hedged transactions are recognized in earnings. Changes in the fair value of foreign exchange forward contracts due to changes in time value are included in the assessment of effectiveness. Our derivatives are not subject to any credit contingent features. We manage credit risk with counter-parties by trading among several counter-parties and we review our counter-parties’ credit at least quarterly. Property and Equipment Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives. Computer hardware and software are typically amortized over three to five years, and furniture and fixtures over three to eight years. Leasehold improvements are amortized over the shorter of their useful lives or the remaining terms of the related leases. Property and equipment under capital leases are amortized over the lesser of the lease terms or their estimated useful lives. Maintenance and repairs are charged to expense when incurred; additions and improvements are capitalized. When an item is sold or retired, the cost and related accumulated depreciation is relieved, and the resulting gain or loss, if any, is recognized in income. Software Development Costs We incur costs to develop computer software to be licensed or otherwise marketed to customers. Research and development costs are expensed as incurred, except for costs of internally developed or externally purchased software that qualify for capitalization. Development costs for software to be sold externally incurred subsequent to the establishment of technological feasibility, but prior to the general release of the product, are capitalized and, upon general release, are amortized using the greater of either the straight-line method over the expected life of the related products or based upon the pattern in which economic benefits related to such assets are realized. The straight-line method is used if it approximates the same amount of expense as that calculated using the ratio that current period gross product revenues bear to total anticipated gross product revenues. No development costs for software to be sold externally were capitalized in 2018 , 2017 or 2016 . In 2018 and 2017 , we acquired capitalized software of $0.8 million and $6.0 million , respectively. These assets are included in acquired intangible assets in the accompanying Consolidated Balance Sheets. Goodwill, Acquired Intangible Assets and Long-lived Assets Goodwill is the amount by which the purchase price in a business acquisition exceeds the fair values of net identifiable assets on the date of purchase. Goodwill is evaluated for impairment annually, as of the end of the third quarter, or more frequently if events or changes in circumstances indicate that the asset might be impaired. Factors we consider important, on an overall company basis and reportable-segment basis, when applicable, that could trigger an impairment review include significant under-performance relative to historical or projected future operating results, significant changes in our use of the acquired assets or the strategy for our overall business, significant negative industry or economic trends, a significant decline in our stock price for a sustained period and a reduction of our market capitalization relative to net book value. Our annual goodwill impairment test is based on either a qualitative (Step 0) or quantitative (Step 1) assessment, and is designed to determine whether we believe it is more likely than not that the fair values of our reporting units exceed their carrying values. A Step 0 assessment includes a review of qualitative factors including company specific (financial performance and long-range plans), industry, and macroeconomic factors, and a consideration of the fair value of each reporting unit at the last valuation date. A Step 1 assessment is a quantitative analysis that compares the fair value of the reporting unit to its carrying value. If the reporting unit’s carrying value exceeds its fair value, we record an impairment loss equal to the difference between the carrying value of goodwill and its implied fair value. We estimate the fair values of our reporting units using discounted cash flow valuation models. Those models require estimates of future revenues, profits, capital expenditures, working capital, terminal values based on revenue multiples, and discount rates for each reporting unit. We estimate these amounts by evaluating historical trends, current budgets, operating plans and industry data. We completed our annual goodwill impairment review as of July 1, 2018 based on a Step 0 assessment and concluded that no impairment charge was required as of that date. Long-lived assets primarily include property and equipment and acquired intangible assets with finite lives (including purchased software, customer lists and trademarks). Purchased software is amortized over periods up to 11 years, customer lists are amortized over periods up to 12 years and trademarks are amortized over periods up to 12 years. We review long-lived assets for impairment when 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. An impairment test is based on a comparison of the undiscounted cash flows to the recorded value of the asset or asset group. If impairment is indicated, the asset is written down to its estimated fair value based on a discounted cash flow analysis. Advertising Expenses Advertising costs are expensed as incurred. Total advertising expenses incurred were $2.9 million , $2.5 million and $2.1 million in 2018 , 2017 and 2016 , respectively and are included in sales and marketing expenses in the accompanying Consolidated Statements of Operations. Income Taxes Our income tax expense includes U.S. and international income taxes. Certain items of income and expense are not reported in tax returns and financial statements in the same year. The tax effects of these differences are reported as deferred tax assets and liabilities. Deferred tax assets are recognized for the estimated future tax effects of deductible temporary differences and tax operating loss and credit carryforwards. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. We assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that it is more likely than not that all or a portion of deferred tax assets will not be realized, we establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we include an expense within the tax provision in the Consolidated Statements of Operations. Comprehensive Income (Loss) Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss), which includes foreign currency translation adjustments, changes in unrecognized actuarial gains and losses (net of tax) related to pension benefits, unrealized gains and losses on hedging instruments and unrealized gains and losses on marketable securities. For the purposes of comprehensive income disclosures, we do not record tax provisions or benefits for the net changes in the foreign currency translation adjustment, as we intend to reinvest permanently undistributed earnings of our foreign subsidiaries. Accumulated other comprehensive loss is reported as a component of stockholders’ equity and, as of September 30, 2018 and 2017 , was comprised of cumulative translation adjustment losses of $66.4 million and $54.6 million , respectively, unrecognized actuarial losses related to pension benefits of $27.0 million ( $19.2 million net of tax) and $24.7 million ( $17.6 million net of tax), respectively, unrecognized gain on hedging instruments of $0.4 million ( $0.4 million net of tax) and unrecognized loss of $1.8 million ( $1.5 million net of tax), respectively, and unrecognized losses on marketable securities of $0.4 million and $0.1 million , respectively. Earnings per Share (EPS) Basic EPS is calculated by dividing net income by the weighted average number of shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic earnings per share. Diluted EPS is calculated by dividing net income by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, restricted shares and restricted stock units using the treasury stock method. The calculation of the dilutive effect of outstanding equity awards under the treasury stock method includes consideration of proceeds from the assumed exercise of stock options, unrecognized compensation expense and any tax benefits as additional proceeds. Due to the net loss generated in the year ended September 30, 2016, approximately 1.7 million restricted stock units have been excluded from the computation of diluted EPS in that year as the effect would have been anti-dilutive. The following table presents the calculation for both basic and diluted EPS: Year ended September 30, 2018 2017 2016 (in thousands, except per share data) Net income (loss) $ 51,987 $ 6,239 $ (54,465 ) Weighted average shares outstanding 116,390 115,523 114,612 Dilutive effect of employee stock options, restricted shares and restricted stock units 1,768 1,833 — Diluted weighted average shares outstanding 118,158 117,356 114,612 Basic earnings (loss) per share $ 0.45 $ 0.05 $ (0.48 ) Diluted earnings (loss) per share $ 0.44 $ 0.05 $ (0.48 ) Stock-Based Compensation We measure the compensation cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost is recognized over the period during which an employee is required to provide service in exchange for the award. See Note K. Equity Incentive Plan for a description of the types of stock-based awards granted, the compensation expense related to such awards and detail of equity-based awards outstanding. See Note G. Income Taxes for detail of the tax benefit related to stock-based compensation recognized in the Consolidated Statements of Operations. Recently Adopted Accounting Pronouncements Stock Compensation In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. We adopted ASU No. 2016-09 in the first quarter of 2018. Effective with the adoption, stock-based compensation excess tax benefits or deficiencies are reflected in the Consolidated Statements of Operations as a component of the provision for income taxes when the awards vest or are settled. Previously they were recognized in equity. Upon adoption, under the modified retrospective transition method, we recognized the previously unrecognized excess tax benefits of $37.0 million as increases in deferred tax assets for tax loss carryovers and tax credits, $36.9 million of which were offset by an increase in our U.S. valuation allowance. Additionally, excess tax benefits from stock-based awards will no longer be separately classified on our Consolidated Statements of Cash Flows as a financing activity apart from other income tax, and will be presented as an operating activity. As a result of the adoption of ASU 2016-09, the Consolidated Statement of |
