Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Matters The Company is regularly involved in litigation and arbitration as well as examinations, inquiries and investigations by various regulatory bodies, including the Securities and Exchange Commission ("SEC"), involving its compliance with, among other things, securities laws, client investment guidelines, laws governing the activities of broker-dealers and other laws and regulations affecting its products and other activities. Legal and regulatory matters of this nature involve or may involve but are not limited to the Company’s activities as an employer, issuer of securities, investor, investment adviser, broker-dealer or taxpayer. In addition, in the normal course of business, the Company discusses matters with its regulators raised during regulatory examinations or is otherwise subject to their inquiry. These matters could result in censures, fines, penalties or other sanctions. The Company accrues for a liability when it is both probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Significant judgment is required in both the determination of probability and the determination as to whether a loss is reasonably estimable. In addition, in the event the Company determines that a loss is not probable, but is reasonably possible, and it becomes possible to develop what the Company believes to be a reasonable range of possible loss, then the Company will include disclosures related to such matter as appropriate and in compliance with ASC 450, Loss Contingencies. The disclosures, accruals or estimates, if any, resulting from the foregoing analysis are reviewed at least quarterly and adjusted to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular matter. Based on information currently available, available insurance coverage and established reserves, the Company believes that the outcomes of its legal and regulatory proceedings are not likely, either individually or in the aggregate, to have a material adverse effect on the Company’s results of operations, cash flows or its consolidated financial condition. However, in the event of unexpected subsequent developments and given the inherent unpredictability of these legal and regulatory matters, the Company can provide no assurance that its assessment of any claim, dispute, regulatory examination or investigation or other legal matter will reflect the ultimate outcome and an adverse outcome in certain matters could, from time to time, have a material adverse effect on the Company’s results of operations or cash flows in particular quarterly or annual periods. In re Virtus Investment Partners, Inc. Securities Litigation; formerly Tom Cummins v. Virtus Investment Partners Inc. et al On February 20, 2015, a putative class action complaint alleging violations of certain provisions of the federal securities laws was filed by an individual shareholder against the Company and certain of the Company’s current officers (the “defendants”) in the United States District Court for the Southern District of New York (the "Court"). On April 21, 2015, three plaintiffs, including the original plaintiff, filed motions to be appointed lead plaintiff and, on June 9, 2015, the Court appointed Arkansas Teachers Retirement System lead plaintiff. On August 21, 2015, plaintiff filed a Consolidated Class Action Complaint (the “Consolidated Complaint”) amending the originally filed complaint, which was purportedly filed on behalf of all purchasers of the Company’s common stock between January 25, 2013 and May 11, 2015 (the “Class Period”). The Consolidated Complaint alleges that, during the Class Period, the defendants disseminated materially false and misleading statements and concealed material adverse facts relating to certain funds formerly subadvised by F-Squared Investments Inc. ("F-Squared"). The Consolidated Complaint alleges claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 10b-5. The plaintiff seeks to recover unspecified damages. A motion to dismiss the Consolidated Complaint was filed on behalf of the Company and the other defendants on October 21, 2015. On July 1, 2016, the Court entered an opinion and order granting in part, and denying in part, the motion to dismiss, narrowing Plaintiff's claims under Sections 10(b) and 20(a) of the Exchange Act and dismissing one of the defendants from the suit. The remaining defendants' Answer to the Consolidated Complaint was filed on August 5, 2016. The Company believes that the suit is without merit and intends to defend it vigorously. The Company believes that there is not a material loss that is probable and reasonably estimable related to this claim. Mark Youngers v.

The complaint alleges claims against the Company, certain of the Company’s officers and affiliates, and certain other parties (the “defendants”).

On July 1, 2016, the Court entered an opinion and order granting in part, and denying in part, the motion to dismiss. The Court dismissed four causes of action entirely and a fifth cause of action with respect to a portion of the Class Period. The Court also dismissed all claims against ten defendants named in the Complaint. The Court held that Plaintiff's may pursue certain securities claims under Sections 10(b) and 20(a) of the Exchange Act and Section 12 of the Securities Act of 1933.

The defendants intend to file a motion to certify an interlocutory appeal of the July 1, 2016 order to the Court of Appeals for the Second Circuit on or before August 26, 2016. Oral argument on the motion is scheduled for October 7, 2016. The Company believes that the suit has no basis in law or fact and intends to defend it vigorously. The Company believes that there is not a material loss that is probable and reasonably estimable related to this claim.
