New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Deferred Taxes On January 1, 2017, Federated adopted Accounting Standards Update (ASU) 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This update requires that deferred tax liabilities and assets be classified as noncurrent on the balance sheet. Management elected the prospective transition method, which did not require the restatement of prior years, and the adoption did not have a material impact on Federated's Consolidated Financial Statements.
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Revenue Recognition On May 28, 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes virtually all existing revenue recognition guidance under GAAP. The update's core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. During the third quarter of 2015, the FASB issued ASU 2015-14, which deferred the effective date of the standard by one year. As a result of the deferral, the update is effective for Federated on January 1, 2018. While early adoption is permitted, Federated does not plan to early adopt in 2017. During 2016, the FASB issued ASU 2016-08, which clarified principal versus agent considerations, ASU 2016-10, which clarified identifying performance obligations and the licensing implementation guidance, ASU 2016-12, which addressed implementation issues and provided additional practical expedients and ASU 2016-20, which provided technical corrections to narrow aspects of the guidance (collectively, with ASU 2014-09, Topic 606). Topic 606 allows for the use of either the retrospective or modified retrospective adoption method. Management has substantially completed evaluating revenue contracts, as well as identifying Federated's customers, performance obligations and material revenue streams. For revenue streams evaluated to date, no changes have been identified as to the timing of revenue recognition. Management has reevaluated the capitalization and amortization policies of deferred sales commission assets, which will result in a shorter amortization period. Contingent deferred sales charges received, which are currently recorded as a reduction of the deferred sales commission asset, will be recorded as revenue. Additionally, consideration payable to a customer (such as payments to a fund for amounts in excess of the fund's expense cap), which is currently recorded as an expense, will be recorded as a reduction of revenue. Management continues to evaluate other potential impacts of adoption, including whether certain costs should be capitalized or expensed based on the criteria for costs to obtain or fulfill a contract, and the new disclosure requirements, as well as available transition methods and the impact of adoption on Federated's Consolidated Financial Statements. Financial Instruments On January 5, 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU significantly revises an entity's accounting related to (1) the classification and measurement of investments in equity securities, including investments in mutual funds and (2) the presentation of certain fair value changes for financial liabilities. The ASU also amends certain disclosure requirements associated with the fair value of financial instruments. The update is effective for Federated on January 1, 2018, and, except for certain provisions, does not permit early adoption. An entity should apply the amendments, with certain exceptions, by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments pertaining to financial liabilities are currently not expected to have a material impact on Federated's Consolidated Financial Statements. Management continues to evaluate the amendments pertaining to equity securities and their potential impact of adoption on Federated's Consolidated Financial Statements. Leases On February 25, 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The core principle is that a lessee should recognize the assets and liabilities that arise from leases on the balance sheet, but Topic 842 retains a distinction between finance and operating leases. The update is effective for Federated on January 1, 2019, with early adoption permitted. The update requires the modified retrospective adoption method. Management is currently evaluating the potential impact of adoption on Federated's Consolidated Financial Statements. Clarifying the Definition of a Business On January 5, 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendments in this update require that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset (or a group of similar identifiable assets), the assets are not considered to be a business. To be considered a business, an acquisition or disposal must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The amendments also narrow the definition of the term "outputs" to be consistent with Topic 606. The ASU is effective for Federated on January 1, 2018, with early adoption permitted in specific circumstances, and is required to be applied prospectively. Management does not expect this update to have a material impact on Federated's Consolidated Financial Statements.
