Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies (a) Contractual Pursuant to various acquisition agreements, Federated has made and may be required to make additional purchase price payments based on a percentage of revenue less certain direct expenses attributable to eligible AUM. The payments could occur through 2019. As of March 31, 2016, liabilities totaling $2.1 million, representing the estimated fair value of future consideration payments, were recorded in Other current liabilities ($0.7 million) and Other long-term liabilities ($1.4 million) (see Note (7) for a discussion regarding the valuation methodology). The liabilities are re-measured at each reporting date with changes in the fair value recognized in Operating Expenses - Other on the Consolidated Statements of Income. Federated may be required to make certain compensation-related payments through 2019 in connection with various significant employment and incentive arrangements. Based on asset levels as of March 31, 2016 and performance goals, payments could total up to $29 million over the remaining terms of the arrangements, including incentive compensation opportunities related to the Federated Kaufmann Large Cap Fund. (b) Guarantees and Indemnifications On an intercompany basis, various wholly owned subsidiaries of Federated guarantee certain financial obligations of Federated Investors, Inc., and Federated Investors, Inc. guarantees certain financial and performance-related obligations of various wholly owned subsidiaries. In addition, in the normal course of business, Federated has entered into contracts that provide a variety of indemnifications. Typically, obligations to indemnify third parties arise in the context of contracts entered into by Federated, under which Federated agrees to hold the other party harmless against losses arising out of the contract, provided the other party's actions are not deemed to have breached an agreed upon standard of care. In each of these circumstances, payment by Federated is contingent on the other party making a claim for indemnity, subject to Federated's right to challenge the other party's claim. Further, Federated's obligations under these agreements may be limited in terms of time and/or amount. It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of Federated's obligations and the unique facts and circumstances involved in each particular agreement. As of March 31, 2016, management does not believe that a material loss related to any of these matters is reasonably possible. (c) Legal Proceedings CCM Rochester, Inc. (CCM). In December 2008, Federated completed the acquisition of certain assets of CCM (f/k/a Clover Capital Management, Inc.), an investment manager that specialized in value investing. The purchase was consummated in the midst of the financial crisis. The payment terms under the Asset Purchase Agreement, dated September 12, 2008 (APA), included an upfront payment of $30 million paid by Federated Investors, Inc. at closing and the opportunity for contingent payments over a five year earn-out period following the acquisition date based on the growth in revenue associated with the acquired assets. Under the APA, in order to reach the maximum contingent payments totaling approximately $55 million, the revenue associated with the acquired assets would have had to have grown at a 30% compound annual growth rate. Under the APA, Federated Investors, Inc. paid CCM an additional $18 million, in the aggregate, in contingent payments for the last three years of the earn-out period. On May 20, 2014, shortly after the final contingent payment was paid to CCM, Federated Investors, Inc. was named as the defendant in a case filed by CCM in the U.S. District Court for the Southern District of New York (CCM Rochester, Inc., f/k/a Clover Capital Management, Inc. v. Federated Investors, Inc., Case No. 14-cv-3600 (S.D.N.Y.)). In this lawsuit, CCM has asserted claims against Federated Investors, Inc. for fraudulent inducement, breach of contract (including CCM’s allegations relating to implied duties of best efforts and good faith and fair dealing) and indemnification based on Federated’s alleged failure to effectively market and distribute the investment products associated with the acquired assets and to pay CCM the maximum contingent payments. CCM seeks approximately $37 million in alleged damages plus attorneys’ fees from Federated Investors, Inc. Federated filed a Motion to Dismiss the lawsuit on the basis that, among other reasons, CCM's claims are implausible, have no factual support, and are contrary to the express terms of the APA and to settled law. On November 25, 2014, the Court issued an order granting Federated's Motion to Dismiss in part and denying Federated's Motion to Dismiss in part. The Court dismissed CCM's claim for breach of contract and for breach of an implied obligation to use best efforts. Under the strict standards applicable to Motions to Dismiss that require the Court to accept the allegations of the Complaint as true and draw all inferences in CCM's favor, the Court concluded that CCM's "claim of fraud is at the edge of plausibility" but specifically noted that "[w]hether CCM can successfully prove facts necessary to support that artfully-pled theory remains to be seen." Federated continues to believe that CCM's claims are meritless and without factual support and intends to continue to vigorously defend this lawsuit as it proceeds through summary judgment. Fact discovery and expert discovery have concluded. Briefing also has been concluded on an evidentiary motion filed by Federated seeking to exclude expert testimony presented by CCM. Federated's evidentiary motion is currently pending before the Court and the Court previously indicated that it would rule on the evidentiary motion before entertaining Federated's motion for summary judgment. A schedule for the filing of Federated's motion for summary judgment has not been set. Federated continues to believe that at all times it acted in good faith and complied with its contractual obligations contained in the APA. As of March 31, 2016, Federated believes a material loss related to this lawsuit is remote, and as such, does not believe this pending lawsuit is material to Federated or its consolidated financial statements. Based on this assessment of the status and nature of CCM's claims, and the current stage of the lawsuit, no loss is estimable. Other Litigation. Federated also has claims asserted and threatened against it in the ordinary course of business. As of March 31, 2016, Federated does not believe that a material loss related to these claims is reasonably possible.
