Organization, Consolidation and Presentation of Financial Statements [Abstract]
THE COMPANY AND BASIS OF PREPARATION	THE COMPANY AND BASIS OF PREPARATION. T. Rowe Price Group, Inc. derives its consolidated revenues and net income primarily from investment advisory services that its subsidiaries provide to individual and institutional investors that invest in a broad range of investment solutions across equity, fixed income, multi-asset, and alternative capabilities. We also provide certain investment advisory clients with related administrative services, including distribution, mutual fund transfer agent, accounting, and shareholder services; participant recordkeeping and transfer agent services for defined contribution retirement plans; brokerage; trust services; and non-discretionary advisory services through model delivery. The investment solutions are provided in a number of vehicles, including the T. Rowe Price U.S. mutual funds ("U.S. mutual funds"), subadvised funds, separately managed accounts, collective investment trusts, and other T. Rowe Price products. The other T. Rowe Price products include: open-ended investment products offered to investors outside the U.S., products offered through variable annuity life insurance plans in the U.S., affiliated private investment funds and collateralized loan obligations. Investment advisory revenues depend largely on the total value and composition of assets under our management. Accordingly, fluctuations in financial markets and in the composition of assets under management impact our revenues and results of operations. BASIS OF PRESENTATION. These unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States. These principles require the use of estimates and reflect all adjustments that are, in the opinion of management, necessary for a fair statement of our results for the interim periods presented. All such adjustments are of a normal recurring nature. Actual results may vary from our estimates. The unaudited financial information contained in these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in our 2023 Annual Report. NEWLY ISSUED BUT NOT YET ADOPTED ACCOUNTING GUIDANCE. In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07 - Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. As required by the guidance, we will adopt the annual disclosures of significant segment expenses that are regularly provided to the chief operating decision maker  in our 2024 year-end reporting. Interim segment reporting will become effective under the amendment on January 1, 2025. In December 2023, the FASB issued Accounting Standards Update No. 2023-09 - Income Taxes (Topic 740) - Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. This amendment is effective for the firm on January 1, 2025. We are currently evaluating the impact of adopting this standard and have not yet determined our transition approach. We have considered all other newly issued accounting guidance that is applicable to our operations and the preparation of our unaudited condensed consolidated statements, including those we have not yet adopted. We do not believe that any such guidance has or will have a material effect on our financial position or results of operations.
