General Information and History

Nationwide VLI Separate Account-4 (the "Variable Account") is a separate investment account of Nationwide Life Insurance Company ("Nationwide"). Nationwide is a stock life insurance company organized under the laws of the State of Ohio in March 1929 with its Home Office at One Nationwide Plaza, Columbus, Ohio 43215. Nationwide provides life insurance, annuities and retirement products. Nationwide is admitted to do business in all states, the District of Columbia, Guam, the U.S. Virgin Islands, and Puerto Rico. Nationwide is a member of the Nationwide group of companies and all of its common stock is owned by Nationwide Financial Services, Inc. ("NFS"), a holding company. Nationwide Corporation owns all of NFS's common stock and is a holding company, as well. All of Nationwide Corporation's common stock is held by Nationwide Mutual Insurance Company (95.2%) and Nationwide Mutual Fire Insurance Company (4.8%), the ultimate controlling persons of the Nationwide group of companies. The Nationwide group of companies is one of America's largest insurance and financial services family of companies, with combined assets of over $197 billion as of December 31, 2015.

Nationwide VLI Separate Account-4

Nationwide VLI Separate Account-4 is a separate account that invests in mutual funds offered and sold to insurance companies and certain retirement plans. Nationwide established the Variable Account on December 3, 1987 pursuant to Ohio law. Although the Variable Account is registered with the SEC as a unit investment trust pursuant to the Investment Company Act of 1940, the SEC does not supervise the management of Nationwide or the management of the Variable Account. Nationwide serves as the custodian of the assets of the Variable Account.

Nationwide Investment Services Corporation (NISC)

The policies are distributed by NISC, located at One Nationwide Plaza, Columbus, Ohio 43215, a wholly owned subsidiary of Nationwide. For policies issued in Michigan, all references to NISC will mean Nationwide Investment Svcs. Corporation. NISC was organized as an Oklahoma corporation in 1981.

The policies will be sold on a continuous basis by licensed insurance agents in those states where the policies may lawfully be sold. Agents are registered representatives of broker dealers registered under the Securities Exchange Act of 1934 who are member firms of the Financial Industry Regulatory Authority (FINRA).

Nationwide paid no underwriting commissions to NISC for each of the separate account’s last three fiscal years.

Services

Nationwide or its affiliates provide services and incur expenses in promoting, marketing, or administrative services to the underlying funds. Nationwide or its affiliates have entered into agreements with the investment advisor and/or distributor for the underlying funds relating to the services Nationwide or its affiliates provide. For these services, some funds agree to pay mutual fund service fee payments based on the average aggregate net assets of the Variable Account (and other separate accounts of Nationwide or life insurance company subsidiaries of Nationwide) invested in the particular underlying fund.

These anticipated mutual fund service fee payments were taken into consideration when determining the expenses necessary to support the policies. Without these mutual fund service fee payments, policy charges would be higher. Generally, Nationwide expects to receive somewhere between 0.10% to 0.55% (an annualized rate of the daily net assets of the Variable Account) from the funds offered in the policies. What is actually received depends upon many factors, including but not limited to the type of fund (i.e., money market funds generally pay less mutual fund service fee payments than other fund types) and the types of services for which an underlying fund, or its distributor or advisor, pays mutual fund service fee payments.

Distribution, Promotional, and Sales Expenses

In addition to or partially in lieu of commission, Nationwide may pay the selling firms a marketing allowance, which is based on the firm's ability and demonstrated willingness to promote and market Nationwide's products. How any marketing allowance is spent is determined by the firm, but generally will be used to finance firm activities that may contribute to the promotion and marketing of Nationwide's products. Nationwide makes certain assumptions about the amount of marketing allowance it will pay and takes these assumptions into consideration when it determines the charges that will be assessed under the policies. Nationwide assumed 0.00% of the Commissionable Target Premium for

marketing allowance when determining the charges for the contracts. The actual amount of the marketing allowance may be higher or lower than this assumption. If the actual amount of marketing allowance paid is more than what was assumed, Nationwide will fund the difference. If the actual amount of marketing allowance paid is less than what was assumed, Nationwide may use the excess to pay other sales expenses, non-sales expenses, and/or profit. For more information about marketing allowance or how a particular selling firm uses marketing allowances, consult with your registered representative.

Commissionable Target Premium (CTP) is an amount used in the calculation of the Premium Load and total compensation Nationwide pays. CTP is actuarially derived based on the Base Policy Specified Amount, the Insured’s characteristics and the death benefit option of the policy.

Underwriting Procedure

Nationwide underwrites the policies issued through Nationwide VLI Separate Account-4. The policy's cost of insurance depends upon the Insured's Issue Age, underwriting class, and the length of time the policy has been In Force. The rates will vary depending upon tobacco use and other risk factors. Monthly cost of insurance rates will not exceed those guaranteed in the policy.

Guaranteed cost of insurance rates for base coverage and coverage pursuant to the Supplemental Insurance Rider under policies issued on a non-medical basis are based on (i) the 2001 Commissioners' Standard Ordinary 80% Male Mortality Table, (ii) Attained Age, (iii) Substandard Ratings, and (iv) tobacco distinct status. Guaranteed cost of insurance rates for base coverage and coverage pursuant to the Supplemental Insurance Rider under policies issued on a medical basis are based on (i) either (a) the 2001 Commissioners' Standard Ordinary 100% Male Mortality Table or (b) the 2001 Commissioners' Standard Ordinary 100% Female Mortality Table, (ii) Attained Age, (iii) Substandard Ratings, and (iv) tobacco distinct status. Guaranteed cost of insurance rates for base coverage and coverage pursuant to the Supplemental Insurance Rider on substandard risks will equal the guaranteed cost of insurance rates for standard risks times a percentage greater than 100%.

The underwriting class of an Insured may affect the cost of insurance rate. There are three underwriting classes into which Insureds are placed, depending on the Insureds' mortality characteristics: Guaranteed Issue, Simplified Issue, and Regular Issue. In an otherwise identical policy, an Insured in the Regular Issue underwriting class will have a lower cost of insurance than an Insured in the Guaranteed Issue or Simplified Issue underwriting class.

The rating class is determined using questionnaires, medical records, and physical exams, depending on the amount of insurance and the attributes of the Insured. Nationwide may underwrite using short-form questionnaires or abbreviated medical evaluations.

Net Amount at Risk

The policy's cost of insurance is also dependent on the policy's Net Amount At Risk. The Net Amount At Risk is allocated between coverage provided by the base policy and coverage provided by the Supplemental Insurance Rider. The Net Amount At Risk for the base policy is the base policy Death Benefit minus the policy's Cash Value. The Net Amount At Risk for the Supplemental Insurance Rider is the Rider Death Benefit (as described in the "Supplemental Insurance Rider" sub-section of the "Policy and Rider Charges" section of the prospectus).

Illustrations

Nationwide will provide illustrations of future benefits under the policy before the policy is purchased and upon request thereafter. Nationwide may assess a $25 fee for this service to persons who request more than one policy illustration during a policy year.

Note: The policy owner selects the Premium amount and frequency shown in the policy illustration to show Nationwide how much Premium the policy owner intends to pay and when. Illustrated Premium and hypothetical rates of return are not guaranteed. Investment Experience varies over time, is rarely the same year-over-year, and may be negative. Because the policy is a variable universal life insurance policy with the potential for unfavorable Investment Experience, including extended periods of significant stock market decline, additional Premium may be required to meet a policy owner's goals and/or to prevent the policy from Lapsing. Generally, variable universal life insurance is considered a long-term investment. Policy owners should weigh the investment risk and costs associated with the policy against their objectives, time horizon, risk tolerance, and ability to pay additional Premium if necessary.

Rating Agencies

Independent financial rating services, including Moody's, Standard & Poor's and A.M. Best Company rank and rate Nationwide. The purpose of these ratings is to reflect the financial strength or claims-paying ability of Nationwide. The ratings are not intended to reflect the Investment Experience or financial strength of the Variable Account. Nationwide may advertise these ratings from time to time. In addition, Nationwide may include in certain advertisements, endorsements in the form of a list of organizations, individuals or other parties which recommend Nationwide or the policies. Furthermore, Nationwide may occasionally include in advertisements comparisons of currently taxable and tax deferred investment programs, based on selected tax brackets, or discussions of alternative investment vehicles and general economic conditions.

Money Market Yields

Nationwide may advertise the "yield" and "effective yield" for the money market Sub-Account. Yield and effective yield are annualized, which means that it is assumed that the underlying mutual fund generates the same level of net income throughout a year.

Yield is a measure of the net dividend and interest income earned over a specific seven-day period (which period will be stated in the advertisement) expressed as a percentage of the offering price of the underlying mutual fund's units. The effective yield is calculated similarly, but reflects assumed compounding, calculated under rules prescribed by the SEC. Thus, effective yield will be slightly higher than yield, due to the compounding.

Historical Performance of the Sub-Accounts

Nationwide will advertise historical performance of the Sub-Accounts in accordance with SEC prescribed calculations. Performance information is annualized. However, if a Sub-Account has been available in the Variable Account for less than one year, the performance information for that Sub-Account is not annualized. Performance information is based on historical earnings and is not intended to predict or project future results.

Additional Materials

Nationwide may provide information on various topics to owners and prospective purchasers in advertising, sales literature, or other materials.

Tax Definition of Life Insurance

Section 7702(b)(1) of the Internal Revenue Code provides that if one of two alternate tests is met, a policy will be treated as life insurance for federal tax purposes. The two tests are referred to as the Guideline Premium/Cash Value Corridor Test and the Cash Value Accumulation Test. Both tests are available to flexible premium policies such as this one.

The tables that follow show, numerically, the requirements for each test.

Cash Value Accumulation Test

The Cash Value Accumulation Test requires the Death Benefit to exceed an applicable percentage of the cash value. These applicable percentages are calculated by determining net single premiums, as defined in Code Section 7702(b), for each policy year given a set of actuarial assumptions. The relevant material assumptions include an interest rate of 4% and 2001 CSO guaranteed mortality as prescribed in Revenue Code Section 7702 for the Cash Value Accumulation Test. The resulting net single premiums are then inverted (i.e., multiplied by 1/net single premium) to give the applicable cash value percentages. These premiums vary with the age, sex, and risk classification of the Insured.

The table below provides an example of applicable percentages for the Cash Value Accumulation Test. This example is for a male, non-tobacco, Issue Age 45, and non-medically underwritten.

Item 29. Indemnification

Provision is made in Nationwide’s Amended and Restated Code of Regulations and expressly authorized by the General Corporation Law of the State of Ohio, for indemnification by Nationwide of any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that such person is or was a director, officer or employee of Nationwide, against expenses, including attorneys fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, to the extent and under the circumstances permitted by the General Corporation Law of the State of Ohio.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 ("Act") may be permitted to directors, officers or persons controlling Nationwide pursuant to the foregoing provisions, Nationwide has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
