Debt Disclosure [Abstract]
Debt Disclosure	Debt On June 5, 2017, Federated entered into an unsecured Third Amended and Restated Credit Agreement by and among Federated, certain of its subsidiaries as guarantors party thereto, a syndicate of ten banks as Lenders party thereto, PNC Bank, National Association as administrative agent, PNC Capital Markets LLC, as sole bookrunner and joint lead arranger, Citigroup Global Markets, Inc., as joint lead arranger, Citibank, N.A. as syndication agent, and TD Bank, N.A. as documentation agent (Credit Agreement). The Credit Agreement amended and restated Federated's prior unsecured Second Amended and Restated Credit Agreement, which was dated June 24, 2014 and scheduled to mature on June 24, 2019 (Prior Credit Agreement). The Credit Agreement refinanced $200 million available on the revolving credit facility and $178.5 million outstanding on the term loan facility under the Prior Credit Agreement, replacing both with a $375 million revolving credit facility which has an additional $200 million available via an optional increase (or accordion) feature. The interest on the revolving credit facility is calculated at the monthly London Interbank Offering Rate (LIBOR) plus a spread. The borrowings under the revolving credit facility may include up to $25 million for which interest is calculated at the daily LIBOR plus a spread (Swing Line). Federated had no borrowings under the previous revolving credit facility. The Credit Agreement does not include a term loan facility. On July 1, 2018, Federated entered into an amendment to the Credit Agreement to add certain definitions and to amend certain negative covenants relating to indebtedness, guarantees, and restrictions on dividends, related to the Hermes Acquisition. This amendment contains other customary conditions, representations, warranties and covenants. The Credit Agreement, which expires on June 5, 2022, has no principal payment schedule, but instead requires that any outstanding principal be repaid by the expiration date. Federated, however, may elect to make discretionary principal payments prior to the expiration date. As of September 30, 2018 and December 31, 2017, the amounts outstanding under the revolving credit facility were $160 million and $170 million, respectively, and were recorded as Long-Term Debt on the Consolidated Balance Sheets. The interest rate was 3.229% and 2.486% as of September 30, 2018 and December 31, 2017, respectively, which was calculated at LIBOR plus a spread. The commitment fee under the Credit Agreement currently is 0.125% per annum on the daily unused portion of each Lender's commitment. As of September 30, 2018, Federated has $215 million available for borrowings. The Credit Agreement, similar to the Prior Credit Agreement, includes representations and warranties, affirmative and negative financial covenants, including an interest coverage ratio covenant and a leverage ratio covenant, reporting requirements and other non-financial covenants. Federated was in compliance with all covenants at and during the nine months ended September 30, 2018 (see the Liquidity and Capital Resources section of Management's Discussion and Analysis for additional information). The Credit Agreement also has certain stated events of default and cross default provisions which would permit the lenders/counterparties to accelerate the repayment of debt outstanding if not cured within the applicable grace periods. The events of default generally include breaches of contract, failure to make required loan payments, insolvency, cessation of business, notice of lien or assessment, and other proceedings, whether voluntary or involuntary, that would require the repayment of amounts borrowed. The Credit Agreement also requires certain subsidiaries to enter into a Second Amended and Restated Continuing Agreement of Guaranty and Suretyship to guarantee payment of all obligations incurred through the Credit Agreement.
