(2) The Legal Proceedings section of the prospectus with respect to Nationwide Life Insurance is deleted and replaced in its entirety with the following:

Nationwide Financial Services, Inc. (NFS, or collectively with its subsidiaries, “the Company”) was formed in November 1996. NFS is the holding company for Nationwide Life Insurance Company (NLIC), Nationwide Life and Annuity Insurance Company (NLAIC) and other companies that comprise the life insurance and retirement savings operations of the Nationwide group of companies (Nationwide). This group includes Nationwide Financial Network (NFN), an affiliated distribution network that markets directly to its customer base. NFS is incorporated in Delaware and maintains its principal executive offices in Columbus, Ohio.

The Company is subject to legal and regulatory proceedings in the ordinary course of its business. The Company's legal and regulatory matters include proceedings specific to the Company and other proceedings generally applicable to business practices in the industries in which the Company operates. These matters are subject to many uncertainties, and given their complexity and scope, their outcomes cannot be predicted. Regulatory proceedings could also affect the outcome of one or more of the Company's litigation matters. Furthermore, it is often not possible to determine the ultimate outcomes of the pending regulatory investigations and legal proceedings or to provide reasonable ranges of potential losses with any degree of certainty. Some matters, including certain of those referred to below, are in very preliminary stages, and the Company does not have sufficient information to make an assessment of the plaintiffs' claims for liability or damages. In some of the cases seeking to be certified as class actions, the court has not yet decided whether a class will be certified or (in the event of certification) the size of the class and class period. In many of the cases, the plaintiffs are seeking undefined amounts of damages or other relief, including punitive damages and equitable remedies, which are difficult to quantify and cannot be defined based on the information currently available. The Company believes, however, that based on currently known information, the ultimate outcome of all pending legal and regulatory matters is not likely to have a material adverse effect on the Company's condensed consolidated financial position. Nonetheless, given the large or indeterminate amounts sought in certain of these matters and the inherent unpredictability of litigation, it is possible that such outcomes could materially affect the Company's condensed consolidated financial position or results of operations in a particular quarter or annual period.

The various businesses conducted by the Company are subject to oversight by numerous federal and state regulatory entities, including but not limited to the Securities and Exchange Commission, the Financial Industry Regulatory Authority, the Department of Labor, the Internal Revenue Service, the Federal Reserve Bank and state insurance authorities. Such regulatory entities may, in the normal course, be engaged in general or targeted inquiries, examinations and investigations of the Company and/or its affiliates. The financial services industry has been the subject of increasing scrutiny in connection with a broad spectrum of regulatory issues; with respect to all such scrutiny directed at the Company and/or its affiliates, the Company is cooperating with regulators. The Company will cooperate with Nationwide Mutual Insurance Company (NMIC) insofar as any inquiry, examination or investigation encompasses NMIC’s operations.

On August 15, 2001, NFS and NLIC were named in a lawsuit filed in the United States District Court for the District of Connecticut entitled Lou Haddock, as trustee of the Flyte Tool & Die, Incorporated Deferred Compensation Plan, et al v. Nationwide Financial Services, Inc. and Nationwide Life Insurance Company. On November 18, 2009, the plaintiffs filed a sixth amended complaint amending the list of named plaintiffs and claiming to represent a class of qualified retirement plan trustees under the Employee Retirement Income Security Act of 1974 (ERISA) that purchased variable annuities from NLIC. The plaintiffs allege that they invested ERISA plan assets in their variable annuity contracts and that NLIC and

NFS breached ERISA fiduciary duties by allegedly accepting service payments from certain mutual funds. The complaint seeks damages in an amount equivalent to some or all of the payments allegedly received by NFS and NLIC, other unspecified relief for restitution, declaratory and injunctive relief, and attorneys fees. On November 6, 2009, the Court granted the plaintiffs motion for class certification. On October 21, 2010, the District Court dismissed NFS from the lawsuit. On February 6, 2012, the Second Circuit Court of Appeals vacated the November 6, 2009 order granting class certification and remanded the case back to the District Court for further consideration. On September 6, 2013, the District Court granted the plaintiffs motion for class certification. On December 11, 2014, the plaintiffs filed a 7th Amended Complaint adding another sub class of defendants that held trust platform products. On December 11, 2014, plaintiff filed a motion for preliminary approval of settlement. On January 5, 2015, the Court signed the Order Preliminarily Approving Settlement and Approving Form and Manner of Notice. On March 31, 2015, the Court held a Fairness Hearing. On April 9, 2015, the Court entered the Final Order and Consent Judgment. NFS has made adequate provision for all probable and reasonably estimable losses associated with this settlement.
