Basis of Accounting [Abstract] |
Basis of Accounting | Basis of Presentation The interim Consolidated Financial Statements of Federated Investors, Inc. and its consolidated subsidiaries (collectively, Federated) included herein have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). In the opinion of management, the financial statements reflect all adjustments that are of a normal recurring nature and necessary for a fair presentation of the results for the interim periods presented. In preparing the financial statements, management is required to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results may differ from those estimates, and such differences may be material to the Consolidated Financial Statements. These financial statements should be read in conjunction with Federated's Annual Report on Form 10-K for the year ended December 31, 2015. Certain items previously reported have been reclassified to conform with the current period's presentation.
