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, 2017, filed with the Securities and Exchange Commission (the “SEC”) on February 28, 2018 (the “2017 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 March 31, 2018, the results of its operations for the three months ended March 31, 2018 and 2017 and its cash flows for the three months ended March 31, 2018 and 2017. Certain prior year balances have been reclassified to conform to the current year presentation. Such reclassifications did not affect total revenues, operating income or net income. These statements do not include all of the information and footnotes required by GAAP for annual financial statements. The Condensed Consolidated 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, 2017, which were included in the 2017 Form 10-K. The December 31, 2017 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 months ended March 31, 2018 are not necessarily indicative of the expected results for any subsequent quarters or the full year. In connection with the adoption of ASC 606, the Company revised its presentation of revenues to illustrate its two primary sources of revenues: software-enabled services revenues and license, maintenance and other related revenues. The Company believes its prior presentation of recurring and non-recurring revenue streams is no longer useful, as the license portion of revenue from multi-year term license agreements is now recognized up-front and is no longer annually recurring in nature. Recently Adopted Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-15, Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Accounting Standards Codification (“ASC”) Topic 230, Statement of Cash Flow, and other Topics. ASU 2016-15 is effective for the Company for its first quarter of fiscal 2018 and the guidance requires application using a retrospective method. The impact of the Company’s adoption of ASU 2016-15 to the Company’s Condensed Consolidated Financial Statements was to reflect the presentation of debt prepayment or debt extinguishment costs as cash outflows from financing activities within the Company’s Condensed Consolidated Statement of Cash Flows. The Company adopted ASU 2016-15, which did not have a material impact on the Company’s financial position, results of operations or cash flows. In May 2014, the FASB issued ASU, Revenue from Contracts with Customers (Topic 606). ASC 606 supersedes the revenue recognition requirements in ASC 605 and 985 and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted ASC 606 as of January 1, 2018 using the modified retrospective transition method. See Note 2 for further details. Recent Accounting Pronouncements Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires companies to measure credit losses utilizing a methodology that reflects expected credit losses and requires a consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for the Company for its first quarter of fiscal 2020 and earlier adoption is permitted beginning in the first quarter of fiscal 2019. Application of the ASU is through a cumulative-effect adjustment to retained earnings as of the effective date. The Company is currently evaluating the impact of the pending adoption of ASU 2016-13 on the Company’s Condensed Consolidated Financial Statements. This ASU is not expected to have a material impact on the Company’s financial position, results of operations or cash flows. 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. Additional disclosures will be required to allow the user to assess the amount, timing and uncertainty of cash flows arising from leasing activities. A modified retrospective transition approach is required for leases existing at the time of adoption. ASU 2016-02 is effective for the Company for its first quarter of fiscal 2019 and earlier adoption is permitted. The impact of the Company’s adoption of ASU 2016-02 to the Company’s Condensed Consolidated Financial Statements will be to recognize the majority of the Company’s operating lease commitments as operating lease liabilities and right-of-use assets upon adoption, which will result in a material increase in the assets and liabilities recorded on the Company’s Condensed Consolidated Balance Sheet. The Company is continuing its assessment, which may identify additional impacts this ASU will have on the Company’s Condensed Consolidated Financial Statements and related disclosures and internal controls over financial reporting.
