Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Note 1—Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These accounting principles were applied on a basis consistent with those of the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, filed with the Securities and Exchange Commission (the “SEC”) on February 29, 2016 (the “2015 Form 10-K”). In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments, except as noted elsewhere in the notes to the condensed consolidated financial statements) necessary for a fair statement of its financial position as of June 30, 2016, the results of its operations for the three and six months ended June 30, 2016 and 2015 and its cash flows for the six months ended June 30, 2016 and 2015. These statements do not include all of the information and footnotes required by GAAP for annual financial statements. The financial statements contained herein should be read in conjunction with the audited consolidated financial statements and footnotes as of and for the year ended December 31, 2015, which were included in the 2015 Form 10-K. The December 31, 2015 consolidated balance sheet data were derived from audited financial statements but do not include all disclosures required by GAAP for annual financial statements. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the expected results for any subsequent quarters or the full year. Reclassifications In connection with the acquisition of Advent and the related increase in term license revenues, the Company condensed its presentation of revenues on its Condensed Consolidated Statements of Comprehensive Income to illustrate its two types of revenue streams: recurring revenues and non-recurring revenues. Recurring revenues consist of software-enabled services and maintenance and term licenses. Non-recurring revenues consist of professional services and perpetual licenses. The Company’s prior presentation required that revenues from term license agreements be allocated between license revenue and maintenance revenue, with the license portion being reported together with revenue from perpetual license agreements as “Software licenses”, and the maintenance portion being reported together with maintenance revenue related to perpetual licenses as “Maintenance”. The Company reclassified $3.1 million and $7.4 million from “Software licenses” to “Maintenance and term licenses” for the three and six months ended June 30, 2015, respectively. In connection with the reclassification of revenues, the Company reclassified the related costs of revenues, which were immaterial. The revised presentation better illustrates the nature of the Company’s revenues and costs of revenues by indicating the recurring nature of the license portion of revenue from term license agreements. The Company has not changed its accounting methods for revenue recognition. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The provisions of this ASU are effective for years beginning after December 15, 2016. Early application is permitted. The Company is currently evaluating the impact of this ASU. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU would require lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date; (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessor accounting is largely unchanged under the amendments of this ASU. The provisions of this ASU are effective for years beginning after December 15, 2018. The Company is currently evaluating the impact of this ASU. In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This ASU establishes specific guidance to an organization’s management on their responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern. The provisions of ASU 2014-15 are effective for interim and annual periods beginning after December 15, 2016. This ASU is not expected to have an impact on the Company’s financial position, results of operations or cash flows. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The objective of ASU 2014-09 is to clarify the principles for recognizing revenue by removing inconsistencies and weaknesses in revenue requirements; providing a more robust framework for addressing revenue issues; improving comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and providing more useful information to users of financial statements through improved revenue disclosure requirements. On August 12, 2015, the FASB issued ASU No. 2015-14, deferring the effective date by one year for ASU No. 2014-09. The provisions of ASU No. 2014-09 will be effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted for annual periods beginning after December 15, 2016. The Company is currently evaluating the impact of this standard on its financial position, results of operations and cash flows.
