Contingencies	11.Contingencies The Company is involved from time to time in various legal proceedings, regulatory investigations and claims incident to the normal conduct of business, which may include proceedings that are specific to us and others generally applicable to business practices within the industries in which we operate. A substantial legal liability or a significant regulatory action against us could have an adverse effect on our business, financial condition and on the results of operations in a particular quarter or year. The Company establishes reserves for litigation and similar matters when those matters present material loss contingencies that management determines to be both probable and reasonably estimable in accordance with ASC 450, “Contingencies.” These amounts are not reduced by amounts that may be recovered under insurance or claims against third parties, but undiscounted receivables from insurers or other third parties may be accrued separately. The Company regularly revises such accruals in light of new information. The Company discloses the nature of the contingency when management believes it is reasonably possible the outcome may be significant to the Company’s consolidated financial statements and, where feasible, an estimate of the possible loss. For purposes of our litigation contingency disclosures, “significant” includes material matters as well as other items that management believes should be disclosed. Management’s judgment is required related to contingent liabilities because the outcomes are difficult to predict. Shareholder Derivative Litigation In an action filed on April 18, 2016 in the District Court of Johnson County, Kansas, Hieu Phan v. Ivy Investment Management Company, et al. (Case No. I6CV02338 Div. 4), plaintiff filed a putative derivative action on behalf of the nominal defendant, a mutual fund trust affiliated with the Company, alleging breach of fiduciary duty and breach of contract claims relating to an investment held in the affiliated mutual fund by the Company's registered investment adviser subsidiary. On behalf of the nominal defendant trust, plaintiff filed claims against the Company’s registered investment adviser subsidiary and current and retired trustees of the trust seeking monetary damages and demanding a jury trial. While the Company denies that any of its subsidiaries breached their fiduciary duties to, or committed a breach of the investment management agreement with, the nominal defendant trust, the parties to the litigation reached a settlement. The February 14, 2018 settlement agreement provided a full release for the benefit of defendants and for the payment of $19.9 million (less $6.1 million for attorney’s fees plus nominal costs associated with notice to shareholders), recoverable to the Company through insurance, to the affiliated mutual fund for the benefit of its shareholders. On July 30, 2018, the court entered an order granting final approval of the settlement. 401(k) Plan Class Action Litigation In an action filed on June 23, 2017 and amended on June 26, 2017 in the U.S. District Court for the District of Kansas, Schapker v. Waddell & Reed Financial, Inc., et al, (Case No. 17-2365 D. Kan.), Stacy Schapker, a participant in the Company’s 401(k) and Thrift Plan, as amended and restated (the “401(k) Plan”), filed a lawsuit against the Company, the Company’s Board of Directors, the Administrative Committee of the 401(k) Plan, and unnamed Jane and John Doe Defendants 1-25. On August 7, 2017, plaintiff filed a second amended complaint, which was filed on behalf of the 401(k) Plan and a proposed class of 401(k) Plan participants, purports to assert claims for breach of fiduciary duty and prohibited transactions under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) based on the 401(k) Plan’s offering of investments managed by the Company or its affiliates during a proposed class period of June 23, 2011 to present. The second amended complaint dismissed the Company’s Board of Directors as a defendant and named as defendants the Company, the Compensation Committee of the Company’s Board of Directors, the Administrative Committee of the 401(k) Plan, and the individuals who served on those committees during the proposed class period. Following the denial of their motion to dismiss, on March 8, 2018, defendants filed their answer and defenses to plaintiff’s second amended complaint. On April 23, 2018, the court entered an initial scheduling order, ordering the parties to complete mediation by August 31, 2018. While the Company and the other defendants deny any and all liability with respect to the claims, the parties have reached an agreement in principle to settle the litigation. The parties are finalizing the terms of the proposed settlement, which will be subject to preliminary and final court approval. The payment contemplated by the proposed settlement is recoverable to the Company through insurance. The Company has recorded a liability and offsetting receivable from insurance, as reflected in the Company's consolidated balance sheet.
