Stock options are granted at the discretion of the Board and expire 10 years from the date of the grant. At March 31, 2012, there were 562 options available for future grant under the Plan. The LTIP permits the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance stock awards and stock unit awards based on, or related to, shares of the Company's common stock. On each April 1, the number of shares available for issuance under the LTIP is increased, if applicable, such that the total number of shares available for awards under the LTIP as of any April 1 is equal to 5% of the number of outstanding shares of the Company's common stock on that April 1. As of March 31, 2012, approximately 516 shares were available for future issuance under the LTIP. As of March 31, 2012, the Company has granted non-qualified stock options and restricted stock units under its stock incentive plans. Equity awards granted by the Company under its stock incentive plans generally vest quarterly over a four-year period, except that the shares that would otherwise vest quarterly over the first 12 months do not vest until the first anniversary of the grant. During fiscal 2012, the Company granted a total of 53 stock options and 28 restricted stock units to members of the Company's Board of Directors that vest over a one year period. The Company anticipates that future grants under its stock incentive plans will continue to include both non-qualified stock options and restricted stock units. The Company estimated the fair value of stock options granted using the Black-Scholes formula. The average expected life was determined according to the "simplified method", which is the mid-point between the vesting date and the end of the contractual term. During fiscal 2013, the Company anticipates that it will begin incorporating its historical data into the expected term calculation for stock options granted. At this point, the Company will have an additional year of vesting and will be able to demonstrate significant exercise activity to provide a reasonable basis for incorporating historical data into its expected term of future stock option grants. As a result, during fiscal 2013, the Company anticipates that its calculation of expected term will include a combination of actual exercise data and an assumption on when the remaining outstanding options with similar characteristics will be exercised. The risk-free interest rate is determined by reference to U.S. Treasury yield curve rates with a remaining term equal to the expected life assumed at the date of grant. Forfeitures are estimated based on the Company's historical analysis of actual stock option forfeitures. Expected volatility for the fiscal years ended March 31, 2010, 2011 and 2012 was calculated based on a blended approach that included historical volatility of a peer group, the implied volatility of the Company's traded options with a remaining maturity greater than six months and the historical realized volatility of the Company's common stock from the date of its initial public offering to the respective stock option grant date. The assumptions used in the Black-Scholes option-pricing model are as follows:   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="92%" align="center">

The Company recognized a tax benefit related to stock-based compensation of $7,276 in the year ended March 31, 2012, $5,352 in the year ended March 31, 2011 and $5,135 in the year ended March 31, 2010. As of March 31, 2012, there was approximately $59,081 of unrecognized stock-based compensation expense, net of estimated forfeitures, related to non-vested stock option and restricted stock unit awards that is expected to be recognized over a weighted average period of 2.70 years. To the extent the actual forfeiture rate is different from what the Company has anticipated, stock-based compensation related to these awards will be different from the Company's expectations.

<div> <div class="MetaData"> Net Income per Common Share Basic net income per common share is computed by dividing net income by the weighted average number of common shares during the period. Diluted net income per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and the vesting of restricted stock units. The dilutive effect of such potential common shares is reflected in diluted earnings per share by application of the treasury stock method. The following table sets forth the computation of basic and diluted net income per common share:   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="92%"

<div> <div class="MetaData"> <div> Fair Value of Financial Instruments The carrying amounts of the Company's cash and cash equivalents, accounts receivable and accounts payable approximate their fair values due to the short-term maturity of these instruments. As of March 31, 2012, the Company's short-term investments balance consisted of certificates of deposit. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for such asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value should maximize the use of observable inputs and minimize the use of unobservable inputs. To measure fair value, the Company uses the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs other than Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets and liabilities in active markets; 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 by correlation or other means. 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.   The following table summarizes the composition of the Company's financial assets measured at fair value on a recurring basis at March 31, 2012 and March 31, 2011:   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="92%" align="center"> <tr><td width="76%"> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td></tr> <tr><td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="6" align="center">March 31,</td> <td valign="bottom"> </td></tr> <tr><td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="2" align="center">2012</td> <td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="2" align="center">2011</td> <td valign="bottom"> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Cash and cash equivalents:</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td></tr> <tr><td valign="top"> Money market funds</td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">232,037</td> <td valign="bottom" nowrap="nowrap">  </td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">182,911</td> <td valign="bottom" nowrap="nowrap">  </td></tr></table> All of the Company's financial instruments in the table above were classified and measured as Level 1 instruments.</div></div> </div>

<div> <div class="MetaData"> Foreign Currency Translation The functional currencies of the Company's foreign operations are deemed to be the local country's currency. Assets and liabilities of the Company's international subsidiaries are translated at their respective period-end exchange rates, and revenues and expenses are translated at average currency exchange rates for the period. The resulting balance sheet translation adjustments are included in Other Comprehensive Income (Loss) and are reflected as a separate component of Stockholders' Equity. Foreign currency transaction gains and losses are recorded in "General and administrative expenses" in the Consolidated Statements of Income. The Company recognized net foreign currency transaction losses of $232 in the year ending March 31, 2012, net foreign currency transaction losses of $623 in the year ending March 31, 2011, and net foreign currency transaction losses of $647 in the year ending March 31, 2010. The net foreign currency transaction gains and losses recorded in "General and administrative expenses" include settlement gains and losses on forward contracts disclosed below. To date, the Company has selectively hedged its exposure to foreign currency transaction gains and losses on the balance sheet through the use of forward contracts, which were not designated as hedging instruments. The duration of forward contracts utilized for hedging the Company's balance sheet exposure is generally one to three months. As of March 31, 2012 and March 31, 2011, the Company did not have any forward contracts outstanding. The Company recorded net realized gains of $37 and net realized losses of $48 in general and administrative expenses related to the settlement of a forward exchange contracts in the years ending March 31, 2012 and 2011, respectively. In the future, the Company may enter into additional foreign currency-based hedging contracts to reduce its exposure to significant fluctuations in currency exchange rates on the balance sheet.</div> </div>

allowances totaling $1,420 against its deferred tax assets. Specifically, the Company has a valuation allowance of $1,343 against certain state research tax credits due to uncertainties related to the ability to utilize such state research tax credits before they expire. The Company based its valuation allowance on its estimates of taxable income by legal entity and the period over which its state research tax credits will be recoverable. In addition, the Company has a valuation allowance of $77 against foreign net operating loss carryforwards in a certain international jurisdiction. In assessing the need for a valuation allowance against its net operating loss carryforwards in such international jurisdiction, the Company considered projected future income as part of its analysis. It is the Company's intention to reinvest undistributed earnings of its foreign subsidiaries and thereby infinitely postpone their remittance. As a result, deferred U.S. income taxes have not been provided on undistributed earnings of foreign subsidiaries of the Company. The cumulative amount of unremitted earnings from the foreign subsidiaries that is expected to be permanently reinvested was approximately $5,277 on March 31, 2012. Excess tax benefits related to share-based payments are credited to equity. When determining this excess tax benefit, the Company elected to follow the tax law approach. As a result, the Company's excess tax benefit which was recorded to equity was approximately $16,072 and $7,084 for the years ended March 31, 2012 and 2011, respectively. At March 31, 2012, the Company has state net operating loss (NOL) carryforwards of approximately $2,074 and NOL carryforwards for foreign tax purposes of approximately $6,973. At March 31, 2012, the Company has federal and state research tax credit (R&D credits) carryforwards of approximately $12,250 and $5,155, respectively. The federal research tax credit carryforwards expire from 2022 through 2032, and the state research tax credit carryforwards expire from 2014 through 2027. At March 31, 2012, the Company has federal Alternative Minimum Tax credit carryforwards of $1,586.   The Company conducts business globally and as a result, files income tax returns in the United States and in various state and foreign jurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as the United States, Australia, Canada, Germany, Netherlands and United Kingdom. The Company is not currently under audit in any tax jurisdiction. The following table summarizes the tax years in the Company's major tax jurisdictions that remain subject to income tax examinations by tax authorities as of March 31, 2012. The years subject to income tax examination in the Company's foreign jurisdictions cover the maximum time period with respect to these jurisdictions. Due to NOL carryforwards, in some cases the tax years continue to remain subject to examination with respect to such NOLs.   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="92%" align="center"> <tr><td width="77%"> </td> <td valign="bottom" width="10%"> </td> <td> </td> <td> </td> <td> </td></tr> <tr><td valign="bottom" nowrap="nowrap"> Tax Jurisdiction</td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="2" align="center">Years Subject to Income Tax Examination</td> <td valign="bottom"> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> U.S. Federal</td> <td valign="bottom">  </td> <td valign="bottom" nowrap="nowrap"> </td> <td valign="bottom" nowrap="nowrap" align="right">2001 - Present</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr><td valign="top"> New Jersey</td> <td valign="bottom">  </td> <td valign="bottom" nowrap="nowrap"> </td> <td valign="bottom" nowrap="nowrap" align="right">2002 - Present</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Foreign jurisdictions</td> <td valign="bottom">  </td> <td valign="bottom" nowrap="nowrap"> </td> <td valign="bottom" nowrap="nowrap" align="right">2006 - Present</td> <td valign="bottom" nowrap="nowrap">  </td></tr></table> The calculation of the Company's tax liabilities involves dealing with uncertainties in the application of complex tax regulations in each of its tax jurisdictions. The number of years with open tax audits varies depending on the tax jurisdiction. A number of years may lapse before a particular matter is audited and finally resolved.

2012 of $4,699, if recognized, would favorably affect the effective tax rate. Components of the reserve are classified as either current or long-term in the Consolidated Balance Sheet based on when the Company expects each of the items to be settled. Accordingly, the Company has recorded its unrecognized tax benefits of $4,699 and $4,481 and the related accrued interest and penalties of $784 and $842 in Other Liabilities on the Consolidated Balance Sheet at March 31, 2012 and March 31, 2011, respectively. The Company believes that it is reasonably possible that approximately $404 of its currently remaining unrecognized tax benefits and approximately $201 of related accrued interest and penalties may be realized by the end of the fiscal year ending March 31, 2013 as a result of the lapse of the statute of limitations. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense. In the years ended March 31, 2012, 2011 and 2010, the Company recognized $117, $152 and $138, respectively, of interest and penalties in the Consolidated Statement of Income. </div>

<div> <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="100%"> <tr><td valign="top" width="4%" align="left">2.</td> <td valign="top" align="left">Summary of Significant Accounting Policies </td></tr></table> <div class="MetaData"> Basis of Presentation The consolidated financial statements include the accounts of the Company. All intercompany transactions and balances have been eliminated.</div> <div class="MetaData"> Use of Estimates The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make judgments and estimates that affect the amounts reported in the Company's consolidated financial statements and the accompanying notes. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. The amounts of assets and liabilities reported in the Company's balance sheets and the amounts of revenues and expenses reported for each of its periods presented are affected by estimates and assumptions, which are used for, but not limited to, the accounting for revenue recognition, allowance for doubtful accounts, income taxes and related reserves, stock-based compensation and accounting for research and development costs. Actual results could differ from those estimates. </div> <div class="MetaData"> Revenue Recognition The Company derives revenues from two primary sources: software licenses and services. Services include customer support, consulting, assessment and design services, installation services and training. A typical sales arrangement includes both of these sources. For sales arrangements involving multiple elements, the Company recognizes revenue using the residual method. Under the residual method, the Company allocates and defers revenue for the undelivered elements based on fair value and recognizes the difference between the total arrangement fee and the amount deferred for the undelivered elements as revenue. The determination of fair value of the undelivered elements in multiple-element arrangements is based on the price charged when such elements are sold separately, which is commonly referred to as vendor-specific objective-evidence, or VSOE. The Company's software licenses typically provide for a perpetual right to use the Company's software and are sold on a per-copy basis, on a capacity basis or as site licenses. Software licenses sold on a capacity basis provide the customer with unlimited licenses of specified software products based on a defined level of terabytes of data under management. Site licenses give the customer the additional right to deploy the software on a limited basis during a specified term. The Company recognizes software revenue through direct sales channels upon receipt of a purchase order or other persuasive evidence and when all other basic revenue recognition criteria are met as described below. The Company recognizes software revenue through all indirect sales channels on a sell-through model. A sell-through model requires that the Company recognize revenue when the basic revenue recognition criteria are met as described below and these channels complete the sale of the Company's software products to the end-user. Revenue from software licenses sold through an original equipment manufacturer partner is recognized upon the receipt of a royalty report or purchase order from that original equipment manufacturer partner. Services revenue includes revenue from customer support and other professional services. Customer support includes software updates on a when-and-if-available basis, telephone support, integrated web-based support and bug fixes or patches. Customer support revenue is recognized ratably over the term of the customer support agreement, which is typically one year. To determine the price for the customer support element when sold separately, the Company primarily uses historical renewal rates. Historical renewal rates are supported by performing an analysis in which the Company segregates its customer support renewal contracts into different classes based on specific criteria including, but not limited to, the dollar amount of the software purchased, the level of customer support being provided and the distribution channel. As a result of this analysis, the Company has concluded that it has established VSOE for the different classes of customer support when the support is sold as part of a multiple-element sales arrangement. The Company's determination of fair value for customer support has not changed for the periods presented. The Company's other professional services include consulting, assessment and design services, installation services and training. Other professional services provided by the Company are not mandatory and can also be performed by the customer or a third-party. In addition to a signed purchase order, the Company's consulting, assessment and design services and installation services are, in some cases, evidenced by a Statement of Work, which defines the specific scope of such services to be performed when sold and performed on a stand-alone basis or included in multiple-element sales arrangements. Revenues from consulting, assessment and design services and installation services are based upon a daily or weekly rate and are recognized when the services are completed. Training includes courses taught by the Company's instructors or third-party contractors either at one of the Company's facilities or at the customer's site. Training fees are recognized after the training course has been provided. Based on the Company's analysis of such other professional services transactions sold on a stand-alone basis, the Company has concluded it has established VSOE for such other professional services when sold in connection with a multiple-element sales arrangement. The Company generally performs its other professional services within 90 days of entering into an agreement. The Company's determination of fair value for other professional services has not changed for the periods presented. The Company has analyzed all of the undelivered elements included in its multiple-element sales arrangements and determined that VSOE of fair value exists to allocate revenues to services. Accordingly, assuming all basic revenue recognition criteria are met, software revenue is recognized upon delivery of the software license using the residual method. The Company considers the four basic revenue recognition criteria for each of the elements as follows:   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="100%"> <tr><td width="4%"> </td> <td valign="top" width="1%" align="left"></td> <td valign="top" width="1%"> </td> <td valign="top" align="left"> Persuasive evidence of an arrangement with the customer exists.    The Company's customary practice is to require a purchase order and, in some cases, a written contract signed by both the customer and the Company, or other persuasive evidence that an arrangement exists prior to recognizing revenue related to an arrangement. </td></tr></table>   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="100%"> <tr><td width="4%"> </td> <td valign="top" width="1%" align="left"></td> <td valign="top" width="1%"> </td> <td valign="top" align="left"> Delivery or performance has occurred.    The Company's software applications are either physically or electronically delivered to customers with standard transfer terms such as FOB shipping point. Software and/or software license keys for add-on orders or software updates are typically delivered in an electronic format. If products that are essential to the functionality of the delivered software in an arrangement have not been delivered, the Company does not consider delivery to have occurred. Services revenue is recognized when the services are completed, except for customer support, which is recognized ratably over the term of the customer support agreement, which is typically one year. </td></tr></table>   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="100%"> <tr><td width="4%"> </td> <td valign="top" width="1%" align="left"></td> <td valign="top" width="1%"> </td> <td valign="top" align="left"> Vendor's fee is fixed or determinable.    The fee customers pay for software applications, customer support and other professional services is negotiated at the outset of a sales arrangement.

However, if an arrangement does include an acceptance clause, revenue for such an arrangement is deferred and recognized upon acceptance. Acceptance occurs upon the earliest of receipt of a written customer acceptance, waiver of customer acceptance or expiration of the acceptance period. </div> <div class="MetaData"> Net Income per Common Share Basic net income per common share is computed by dividing net income by the weighted average number of common shares during the period. Diluted net income per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and the vesting of restricted stock units. The dilutive effect of such potential common shares is reflected in diluted earnings per share by application of the treasury stock method. The following table sets forth the computation of basic and diluted net income per common share:   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="92%"

Based on the Company's software development process, technological feasibility is established upon completion of a working model, which also requires certification and extensive testing. Costs incurred by the Company between completion of the working model and the point at which the product is ready for general release are immaterial. </div> <div class="MetaData"> Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable consist of amounts due to the Company from normal business activities. The Company maintains an allowance for estimated losses resulting from the inability of its customers to make required payments. The Company estimates uncollectible amounts based upon historical bad debts, evaluation of current customer receivable balances, age of customer receivable balances, the customer's financial condition and current economic trends.</div> <div> <div class="MetaData"> Accounting for Income Taxes As part of the process of preparing financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves estimating actual current tax exposure, including assessing the risks associated with tax audits, and assessing temporary differences resulting from different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities. As of March 31, 2012, the Company had net deferred tax assets of approximately $38,578, which were primarily related to federal and state research tax credit carryforwards, stock-based compensation and foreign net operating loss carryforwards. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income, and to the extent that the Company believes recovery is not likely, the Company establishes a valuation allowance. As of March 31, 2012, the Company maintains a valuation allowance against its deferred tax assets totaling $1,420 primarily related to the uncertainty of the Company's ability to utilize certain state research tax credits before they expire. The Company based its valuation allowance on its estimates of taxable income by legal entity and the period over which its state research tax credits will be recoverable. The calculation of the Company's tax liabilities involves dealing with uncertainties in the application of complex tax regulations in each of its tax jurisdictions. The number of years with open tax audits varies depending on the tax jurisdiction. A number of years may lapse before a particular matter is audited and finally resolved. The Company applies the guidance issued to address the accounting for uncertain tax positions. This guidance clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements as well as provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition.   As of March 31, 2012, the Company had unrecognized tax benefits of $4,699, all of which, if recognized, would favorably affect the effective tax rate. In addition, the Company had accrued interest and penalties of $784 related to the unrecognized tax benefits. Interest and penalties, if any, related to unrecognized tax benefits are recorded in income tax expense. Components of the reserve are classified as either current or long-term in the Consolidated Balance Sheet based on when the Company expects each of the items to be settled.</div> <div class="MetaData"> <div> Cash and Cash Equivalents The Company considers all highly liquid investments purchased with maturities of three months or less at the date of purchase to be cash equivalents. As of March 31, 2012, the Company's cash and cash equivalents balance consisted primarily of money market funds.</div></div></div> <div class="MetaData"> <div class="MetaData"> Concentration of Credit Risk The Company grants credit to customers in a wide variety of industries worldwide and generally does not require collateral. Credit losses relating to these customers have been minimal. Sales through the Company's reseller and original equipment manufacturer agreements with Dell totaled approximately 22%, 23% and 24% of total revenues for the years ended March 31, 2012, 2011 and 2010, respectively. Dell accounted for 25% of accounts receivable as of both March 31, 2012 and 2011. Sales through the Company's distribution agreement with Arrow Enterprise Computing Solutions, Inc. ("Arrow") totaled approximately 26%, 25% and 24% of total revenues for the years ended March 31, 2012, 2011 and 2010, respectively. Arrow accounted for approximately 30% and 32% of total accounts receivable as of March 31, 2012 and 2011, respectively.</div> <div class="MetaData"> <div> Fair Value of Financial Instruments The carrying amounts of the Company's cash and cash equivalents, accounts receivable and accounts payable approximate their fair values due to the short-term maturity of these instruments. As of March 31, 2012, the Company's short-term investments balance consisted of certificates of deposit. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for such asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value should maximize the use of observable inputs and minimize the use of unobservable inputs. To measure fair value, the Company uses the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs other than Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets and liabilities in active markets; 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 by correlation or other means. 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.   The following table summarizes the composition of the Company's financial assets measured at fair value on a recurring basis at March 31, 2012 and March 31, 2011:   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="92%" align="center"> <tr><td width="76%"> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td></tr> <tr><td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="6" align="center">March 31,</td> <td valign="bottom"> </td></tr> <tr><td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="2" align="center">2012</td> <td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="2" align="center">2011</td> <td valign="bottom"> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Cash and cash equivalents:</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td></tr> <tr><td valign="top"> Money market funds</td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">232,037</td> <td valign="bottom" nowrap="nowrap">  </td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">182,911</td> <td valign="bottom" nowrap="nowrap">  </td></tr></table> All of the Company's financial instruments in the table above were classified and measured as Level 1 instruments.</div></div></div> <div class="MetaData"> Property and Equipment Property and equipment are stated at cost, less accumulated depreciation and amortization. The Company provides for depreciation on a straight-line basis over the estimated useful lives of the assets. Computer and related equipment is generally depreciated over eighteen months to three years and furniture and fixtures are generally depreciated over three to five years. Leasehold improvements are amortized over the shorter of the useful life of the improvement or the term of the related lease. Expenditures for routine maintenance and repairs are charged against operations. Major replacements, improvements and additions are capitalized.</div> <div class="MetaData"> Asset Retirement Obligation A liability for the fair value of an asset retirement obligation and corresponding increase to the carrying value of the related leasehold improvements are recorded at the time leasehold improvements are acquired. As of March 31, 2012, the Company maintains office space in the United Kingdom for which the lease agreement requires that the Company return the office space to its original condition upon vacating the premises. Accordingly, the balance of the asset retirement obligation as of March 31, 2012 is $552. </div> <div class="MetaData"> Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine the recoverability of its long-lived assets, the Company evaluates the estimated future undiscounted cash flows that are directly associated with, and that are expected to arise as a direct result of, the use and eventual disposition of the long-lived asset. If the estimated future undiscounted cash flows demonstrate that recoverability is not probable, an impairment loss would be recognized. An impairment loss would be calculated based on the excess carrying amount of the long-lived asset over the long-lived asset's fair value. The fair value is determined based on valuation techniques such as a comparison to fair values of similar assets. There were no impairment charges recognized during the years ended March 31, 2012, 2011 and 2010.</div> <div class="MetaData"> Deferred Revenue Deferred revenues represent amounts collected from, or invoiced to, customers in excess of revenues recognized. This results primarily from the billing of annual customer support agreements, as well as billings for other professional services fees that have not yet been performed by the Company and billings for license fees that are deferred due to one of the revenue recognition criteria not being met. The value of deferred revenues will increase or decrease based on the timing of invoices and recognition of software revenue. The Company expenses internal direct and incremental costs related to contract acquisition and origination as incurred.   Deferred revenue consists of the following:   <table style="border-collapse: collapse;" border="0" cellspacing="0" cellpadding="0" width="92%" align="center"> <tr><td width="77%"> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td></tr> <tr><td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="6" align="center">March 31,</td> <td valign="bottom"> </td></tr> <tr><td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="2" align="center">2012</td> <td valign="bottom"> </td> <td valign="bottom">  </td> <td style="border-bottom: #000000 1px solid;" valign="bottom" colspan="2" align="center">2011</td> <td valign="bottom"> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Current:</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td></tr> <tr><td valign="top"> Deferred software revenue</td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">3,764</td> <td valign="bottom" nowrap="nowrap">  </td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">237</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Deferred services revenue</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom" align="right">121,550</td> <td valign="bottom" nowrap="nowrap">  </td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom" align="right">97,980</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr style="font-size: 1px;"><td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td></tr> <tr><td valign="top"> </td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">125,314</td> <td valign="bottom" nowrap="nowrap">  </td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">98,217</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr style="font-size: 1px;"><td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td></tr> <tr bgcolor="#cceeff"><td valign="top"> Non-current:</td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td></tr> <tr><td valign="top"> Deferred services revenue</td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">22,059</td> <td valign="bottom" nowrap="nowrap">  </td> <td valign="bottom">  </td> <td valign="bottom">$</td> <td valign="bottom" align="right">14,695</td> <td valign="bottom" nowrap="nowrap">  </td></tr> <tr style="font-size: 1px;"><td valign="bottom"> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td valign="bottom">  </td> <td> </td></tr></table></div> <div class="MetaData"> Accounting for Stock-Based Compensation The Company utilizes the Black-Scholes pricing model to determine the fair value of non-qualified stock options on the dates of grant. Restricted stock units are measured based on the fair market value of the underlying stock on the date of grant. The Company recognizes stock-based compensation using the straight-line method for all stock awards. The Company classifies benefits of tax deductions in excess of the compensation cost recognized (excess tax benefits) as a financing item cash inflow with a corresponding operating cash outflow. For the years ended March 31, 2012, 2011 and 2010, the Company includes $16,009, $7,044, and $3,395, respectively, as a financing cash inflow.</div> <div class="MetaData"> Share Repurchases The Company considers all shares repurchased as cancelled shares restored to the status of authorized but unissued shares on the trade date. The aggregate purchase price of the shares of the Company's common stock repurchased is reflected as a reduction to Stockholders' Equity. The Company accounts for shares repurchased as an adjustment to common stock (at par value) with the excess repurchase price allocated between Additional Paid-in Capital and Accumulated Deficit. As a result of the Company's stock repurchases in the fiscal years ended March 31, 2012 and 2011, the Company reduced common stock and additional paid-in capital by $6,799 and $7,246, respectively, and accumulated deficit by $38,840 and $24,212, respectively.</div> <div class="MetaData"> Sales Tax The Company records revenue net of sales tax. </div> <div class="MetaData"> Advertising Costs The Company expenses advertising costs as incurred.

Foreign currency transaction gains and losses are recorded in "General and administrative expenses" in the Consolidated Statements of Income. The Company recognized net foreign currency transaction losses of $232 in the year ending March 31, 2012, net foreign currency transaction losses of $623 in the year ending March 31, 2011, and net foreign currency transaction losses of $647 in the year ending March 31, 2010. The net foreign currency transaction gains and losses recorded in "General and administrative expenses" include settlement gains and losses on forward contracts disclosed below. To date, the Company has selectively hedged its exposure to foreign currency transaction gains and losses on the balance sheet through the use of forward contracts, which were not designated as hedging instruments.

As of March 31, 2012 and March 31, 2011, the Company did not have any forward contracts outstanding. The Company recorded net realized gains of $37 and net realized losses of $48 in general and administrative expenses related to the settlement of a forward exchange contracts in the years ending March 31, 2012 and 2011, respectively.

This update eliminates the option to present the components of other comprehensive income as part of the statement of equity. In December 2011, the FASB issued Accounting Standards Update No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income ("ASU 2011-12"), to defer the effective date of the specific requirement to present items that are reclassified out of accumulated other comprehensive income to net income alongside their respective components of net income and other comprehensive income. All other provisions of this update are effective for the Company in the first quarter of fiscal 2013. The Company does not believe the adoption of this new guidance will have a significant impact on its consolidated financial statements. </div>
