Mar. 31, 2014
Accounting Policies [Abstract] |
Deferred Revenue and Unbilled Receivables [Policy Text Block] | Deferred revenue and unbilled receivables Software license and implementation services that have been performed, but for which the Company has not invoiced the customer, are recorded as unbilled receivables, and invoices that have been issued before the software license and implementation services have been performed are recorded as deferred revenue in the accompanying unaudited condensed consolidated balance sheets. The Company generally invoices for maintenance and support services on a monthly, a quarterly or an annual basis through the maintenance and support period
Basis of presentation | Basis of presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting and applicable quarterly reporting regulations of the Securities and Exchange Commission (“SEC”). In management’s opinion, the accompanying interim unaudited condensed consolidated financial statements include all adjustments necessary for a fair statement of the financial position of the Company as of March 31, 2014, the results of operations for the three months ended March 31, 2014 and cash flows for the three months ended March 31, 2014. Certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with GAAP have been omitted from these interim unaudited condensed consolidated financial statements pursuant to the rules and regulations of the SEC. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (“Annual Report”) filed with the SEC. The condensed consolidated balance sheet as of December 31, 2013 was derived from the Company’s audited consolidated financial statements but does not include all disclosures required by GAAP.
Basis of consolidation | Basis of consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Dollar amounts | Dollar amounts The dollar amounts presented in the tabular data within these footnote disclosures are stated in thousands of dollars, except per unit amounts, or as noted within the context of each footnote disclosure.
Use of estimates | Use of estimates The Company’s management prepares the unaudited condensed consolidated financial statements in accordance with GAAP. The Company makes estimates and assumptions in the preparation of its unaudited condensed consolidated financial statements, and its estimates and assumptions may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. The complexity and judgment required in the Company’s estimation process, as well as issues related to the assumptions, risks and uncertainties inherent in the application of the percentage-of-completion method of accounting, affect the amounts of revenue, expenses, unbilled receivables and deferred revenue. Estimates are also used for, but not limited to, receivables, allowance for doubtful accounts, useful lives of assets, depreciation, income taxes and deferred tax asset valuation, valuation of stock options, other current liabilities and accrued liabilities. Numerous internal and external factors can affect estimates. The critical accounting policies related to the estimates and judgments are discussed in the Company’s Annual Report under management’s discussion and analysis of financial condition and results of operations. There have been no significant changes to the Company’s critical accounting policies as described in the Company’s Annual Report.
Revenue recognition | Revenue recognition The Company derives its revenue from the licensing and implementation of software solutions and associated software maintenance and support. To a lesser extent, the Company’s revenue includes nonsoftware related hosting services. The Company’s arrangements with customers typically include: (a) license fees paid for the use of our solutions either in perpetuity or over a specified term and implementation fees for configuration, implementation and training services and (b) maintenance and support fees related to technical support and software updates. If there is significant uncertainty about contract completion or collectability is not reasonably assured, revenue is deferred until the uncertainty is sufficiently resolved or collectability is reasonably assured. In addition, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred and fees are fixed or determinable. In determining whether professional services revenue should be accounted for separately from license revenue, the Company evaluates whether the professional services are considered essential to the functionality of the software using factors such as: the nature of its software products; whether they are ready for use by the customer upon receipt; the nature of professional services; the availability of services from other vendors; whether the timing of payments for license revenue coincides with performance of services; and whether milestones or acceptance criteria exist that affect the realizability of the software license fee. If the Company determines that professional services revenue should not be accounted for separately from license revenue, the license revenue is recognized together with the professional services revenue using the percentage-of-completion method or completed contract method. The completed contract method is also used for contracts where there is a risk over final acceptance by the customer or for contracts that are short term in nature. The percentage-of-completion computation is measured by the percentage of man-days incurred during the reporting period as compared to the estimated total man-days necessary for each contract for implementation of the software solutions. The Company measures performance under the percentage-of-completion method using total man-day method based on current estimates of man-days to complete the project. The Company believes that for each such project, man-days expended in proportion to total estimated man-days at completion represents the most reliable and meaningful measure for determining a project’s progress toward completion. Under our fixed-fee arrangements, should a loss be anticipated on a contract, the full amount is recorded when the loss is determinable. The Company also licenses software solutions under term license agreements that typically include maintenance during the license term. When maintenance is included for the entire term of the license, there is no renewal rate and the Company has not established vendor specific objective evidence (“VSOE”) of fair value for the maintenance on term licenses. For term license agreements, revenue and the associated costs are deferred until the delivery of the solution and recognized ratably over the remaining license term. For arrangements that include hosting and cloud-based services, the Company allocates the arrangement consideration between the service and other elements and recognize the hosting and cloud-based services fee ratably beginning on the date the customer commences use of the Company's services and continuing through the end of the customer term. The Company’s customer arrangements typically contain multiple elements that include software license, implementation services and post-implementation maintenance and support. For multiple element arrangements involving our nonsoftware services, the Company must (1) determine whether and when each element has been delivered; (2) determine the fair value of each element using the selling price hierarchy of VSOE of fair value, third party evidence (“TPE”), or best estimated selling price ("BESP"), as applicable, and (3) allocate the total price among the various elements based on the selling price method. For multiple-element arrangements that include software and nonsoftware elements such as the Company's hosting service offerings, the Company allocates revenue between the software and software-related elements as a group and any nonsoftware elements based on a relative fair value allocation. The Company determine fair value for each deliverable using this hierarchy and utilizes VSOE of fair value if it exists. In certain instances, the Company may not be able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to the Company's limited experience selling each element separately, not pricing solutions or services within a narrow range, or only having a limited sales history. In addition, TPE may not be available. When the Company is unable to establish selling prices using VSOE or TPE, it uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. For transactions that only include software and software-related elements, the Company continues to account for such arrangements under the software revenue recognition standards which requires it to establish VSOE of fair value to allocate arrangement consideration among multiple deliverables. Maintenance and support revenue includes post-implementation customer support and the right to unspecified software updates and enhancements on a when and if available basis. The Company generally invoices for maintenance and support services on a monthly, quarterly or on an annual basis during the maintenance and support period. The Company recognizes revenue from maintenance arrangements ratably over the period in which the services are provided. Software license and implementation revenue that has been recognized, but for which the Company has not invoiced the customer, is recorded as unbilled receivables. Invoices that have been issued before software license, implementation and maintenance and support revenue has been recognized are recorded as deferred revenue in the accompanying consolidated balance sheets.
Business Combinations Policy [Policy Text Block] | Business Combinations We record tangible and intangible assets acquired and liabilities assumed in business combinations under the purchase method of accounting. Amounts paid for each acquisition are allocated to the assets acquired and liabilities assumed based on their fair values at the date of acquisition. Significant management judgments and assumptions are required in determining the fair value of acquired assets and liabilities, particularly acquired intangible assets. The valuation of purchased intangible assets is based upon estimates of the future performance and cash flows from the acquired business. Each asset is measured at fair value from the perspective of a market participant. The Company uses its best estimates and assumptions to accurately assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year or more from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially established in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill, provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statements of operations.
Internal-use software | Internal-use software Costs incurred to develop internal-use software during the development stage are capitalized, stated at cost, and depreciated using the straight-line method over the estimated useful lives of the assets. Development stage costs generally include salaries and personnel costs and third party contractor expenses associated with internal-use software configuration, coding, installation and testing. Capitalized internal-use software development costs related to the Company's cloud-based offerings were $0.7 million and $0.9 million for the three months ended March 31, 2014 and 2013, respectively. Capitalized internal-use software development costs related to our cloud-based offerings are amortized using the straight-line method over the useful life of the asset. For each of the three months ended March 31, 2014 and 2013, the Company amortized $0.1 million of capitalized internal-use software development costs related to its cloud-based offerings. Capitalized software for internal use is included in property and equipment, net in the unaudited condensed consolidated balance sheets. Amortization of capitalized internal-use software development costs related to the Company's cloud-based offerings is included in cost of license and implementation revenues in the accompanying unaudited condensed consolidated statements of comprehensive income.
Noncash share-based compensation | Noncash share-based compensation The Company measures all share-based payments to its employees based on the grant date fair value of the awards and recognizes expense in the Company’s unaudited consolidated statement of comprehensive income on a straight-line basis over the period during which the recipient is required to perform service (generally over the vesting period of the awards). To date, the Company has granted stock options, Restricted Stock Units (“RSUs”), Stock Appreciation Rights (“SARs”), and Market Stock Units (“MSUs”). RSUs include both time-based awards as well as performance-based awards in which the number of shares that vest are based upon the revenue expected to be earned by the Company from binding customer agreements for the provision of Configure, Price, and Quote (CPQ) solutions. The MSUs are performance-based awards in which the number of shares that vest are based upon the Company’s relative stockholder return. The following table presents the number of shares or units outstanding for each award type as of March 31, 2014 and December 31, 2013, respectively.
Award type |  | March 31, 2014 |  | December 31, 2013
Stock options |  | 993,677 |  |  | 1,160,464 |
Restricted stock units (time based) |  | 1,799,901 |  |  | 1,542,990 |
Restricted stock units (performance based) |  | 34,000 |  |  | — |
Stock appreciation rights |  | 706,111 |  |  | 721,028 |
Market stock units |  | 449,600 |  |  | 469,000 |
Stock options, time based RSUs and SARs vest ratably between two and four years. The actual number of MSUs that will be eligible to vest is based on the total stockholder return of the Company relative to the total stockholder return of the Russell 2000 Index (“Index”) over their respective performance periods, as defined by each award's plan documents. The Company did not grant any stock options or SARs during the three month period ended March 31, 2014. The fair value of the RSUs is based on the closing price of the Company’s stock on the date of grant. The Company estimates the fair value of MSUs on the date of grant using a Monte Carlo simulation model. The determination of fair value of the MSUs is affected by the Company’s stock price and a number of assumptions including the expected volatilities of the Company’s stock and the Index, its risk-free interest rate and expected dividends. The Company’s expected volatility at the date of grant was based on the historical volatilities of the Company and the Index over the performance period. The assumptions used to value the MSUs granted during the three months ended March 31, 2014 were as follows:
| Grant Date
| February 24, 2014 |  | February 11, 2014
Volatility | 51.13% |  | 50.74%
Risk-free interest rate | 0.66% |  | 0.67%
Expected option life in years | 2.85 |  | 2.89
Dividend yield | — |  | —
Earnings per share | Earnings per share The Company computes basic earnings per share by dividing net income by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares and dilutive potential common shares then outstanding. Potential common shares consist of shares issuable upon the exercise of stock options and SARs or the vesting of RSUs and MSUs. Diluted earnings per share reflect the assumed conversion of all dilutive share-based awards using the treasury stock method.
Fair value measurement | . Fair value measurement The Company’s financial assets that are measured at fair value on a recurring basis consisted of $26.7 million and $21.0 million invested in treasury money market funds at March 31, 2014 and December 31, 2013, respectively. The fair value of these accounts is determined based on quoted market prices, which represents level 1 in the fair value hierarchy as defined by Accounting Standard Codification ("ASC") 820, “Fair Value Measurement and Disclosure.
Credit Facility | Credit Facility As of March 31, 2014, $0.2 million of unamortized debt issuance costs related to the Company's revolving credit facility ("Revolver") is included in other long term assets in the unaudited condensed consolidated balance sheets. For each of the three months ended March 31, 2014 and 2013, $12,500 of debt issuance cost amortization is included in Other Expense (Income), net in the unaudited condensed consolidated statements of comprehensive income. As of March 31, 2014, the Company had no outstanding borrowings under the Revolver.
Income taxes | Income taxes At the end of each interim reporting period, the Company estimates its annual effective tax rate to calculate its income tax provision. The estimated effective tax rate includes U.S. federal, state and foreign income taxes and is based on the application of an estimated annual income tax rate applied to the current quarter’s year-to-date pre-tax income. This estimated effective tax rate is used in providing for income taxes on a year-to-date basis and may change in subsequent interim reporting periods. The effective tax rate for the three months ended March 31, 2014 and 2013 was 6% and (196)%, respectively. The difference between the effective tax rate and the federal statutory rate of 34% for the three months ended March 31, 2014 was due primarily to the limitation on the deductibility of certain officers’ compensation, valuation allowances related to losses, and nondeductible acquisition costs. The benefit recorded for the three months ended March 31, 2014 and 2013 was $0.6 million and $1.1 million, respectively. The change between March 31, 2014 and 2013 is primarily attributed to the retroactive reinstatement of the Research and Experimentation ("R&D") tax credit during the first quarter of 2013, which resulted in a $1.4 million discrete benefit recorded in the first quarter of 2013, recording additional valuation allowance due to losses during the first quarter of 2014, and an increase in nondeductible officer's compensation between the two periods. The Internal Revenue Service is currently examining the Company’s 2009 R&D credit. The Company is not aware of any other audits at the present time.

- Definition Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed.
