Organization, Consolidation and Presentation of Financial Statements [Abstract] |
General | 1. GENERAL CSG Systems International, Inc. (the "Company", "CSG", or forms of the pronoun "we") have prepared the accompanying unaudited condensed consolidated financial statements as of September 30, 2025 and December 31, 2024, and for the quarters and nine months ended September 30, 2025 and 2024, in accordance with accounting principles generally accepted in the United States of America (“U.S.”) (“GAAP”) for interim financial information, and pursuant to the instructions to Form 10-Q and the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of our management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of our financial position and operating results have been included. The unaudited Condensed Consolidated Financial Statements (the “Financial Statements”) should be read in conjunction with the Consolidated Financial Statements and notes thereto, together with Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), contained in our Annual Report on Form 10-K for the year ended December 31, 2024 (our “2024 10-K”), filed with the SEC. The results of operations for the quarter and nine months ended September 30, 2025 are not necessarily indicative of the expected results for the entire year ending December 31, 2025.
