Accounting Policies [Abstract] |
BASIS OF PRESENTATION | 1. BASIS OF PRESENTATION Business The Company develops, markets, licenses, and supports customer engagement and digital process automation software applications in addition to the Pega Platform™ for clients that wish to build and extend their own applications. The Company provides consulting, training, support, and hosting services to facilitate the use of its software. Management estimates and reporting The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S.”) requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates. Accounts with reported amounts based on significant estimates and judgments include, but are not limited to, revenue, unbilled receivables, deferred revenue, deferred income taxes, deferred contract costs, income taxes payable, intangible assets, and goodwill. On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”, using the full retrospective method which required that each prior reporting period presented be adjusted to reflect the application of this ASU. See "Note 2. Significant Accounting Policies" for additional information. Principles of consolidation The Company’s consolidated financial statements reflect Pegasystems Inc. and subsidiaries in which the Company holds a controlling financial interest.
