This variable annuity requires that you purchase a living benefit rider, for an additional charge, at the time of purchase of the variable annuity. The living benefit is intended to provide Contract Owners with a guaranteed lifetime income stream beginning on or after age 59½, provided certain conditions are met. The contract is designed for Contract Owners who intend to take regular withdrawals ("Lifetime Withdrawals") each year on or after reaching age 59½. A Contract Owner should not purchase the contract if he or she does not intend to take Lifetime Withdrawals on or after age 59½. Contract Owners should also understand that if they intend to take withdrawals prior to age 59½ ("Early Withdrawals"), intend to take a one-time Non-Lifetime Withdrawal, or intend to take withdrawals in excess of the guaranteed lifetime income withdrawal amount, doing so may result in adverse consequences such as a permanent reduction in rider benefits or automatic termination of the living benefit rider. In addition, currently, there is only one investment option available for direct allocation.

This prospectus utilizes Rate Sheet Supplements to disclose current rates for certain optional benefits available under the contract. The most current Rate Sheet Supplement must be used in conjunction with the prospectus.

Under state insurance laws, Contract Owners have the right, during a limited period of time, to examine their contract and decide if they want to keep it or cancel it. This right is referred to as a "free look" right. The length of this time period depends on state law and may vary depending on whether the purchase is a replacement of another annuity contract. For ease of administration, Nationwide will honor any free look cancellation request that is in good order and received at the Service Center or postmarked within 30 days after the contract issue date (see Right to Examine and Cancel and Contacting the Service Center in the statutory prospectus).

If the Contract Owner elects to cancel the contract pursuant to the free look provision, where required by law, Nationwide will return the greater of the Contract Value or the amount of purchase payment(s) applied during the free look period, less any withdrawals from the contract, and applicable federal and state income tax withholding. Otherwise, Nationwide will return the Contract Value, less any withdrawals from the contract, and applicable federal and state income tax withholding (see Right to Examine and Cancel in the statutory prospectus).

You should review the statutory prospectus, or consult with your financial professional, for additional information about the specific cancellation terms that apply.

Additional information about certain investment products, including variable annuities, has been prepared by the SEC'sstaff and is available at Investor.gov.

This contract may be available through third-party financial intermediaries who charge an investment advisory fee for their services, and these fees are in addition to contract fees and expenses described in this prospectus. If the Contract Ownerelects to pay the investment advisory fees from the Contract Value, this may reduce the death benefit and other benefits under the contract, may be subject to federal and state income taxes, and may be subject to a 10% federal tax penalty.

RISKS
Risk of Loss	Contract Owners of variable annuities can lose money by investing in the contract, including loss of principal (see Principal Risks in the statutory prospectus).
Not a Short-Term Investment	The contract is not a short-term investment and is not appropriate for an investor who needs ready access to cash. Nationwide has designed the contract to offer features, pricing, and investment options that encourage long-term ownership (see Principal Risks in the statutory prospectus). The benefits of tax deferral and living benefit protections also mean that the contract is more beneficial to investors with a long time horizon (see Principal Risks in the statutory prospectus).

Overview of the Contract

Purpose of the Contract

The contract is intended to be a long-term investment vehicle to assist investors in saving for and living in retirement. Nationwide has designed the contract to offer features, pricing, and investment options that encourage long-term ownership. The contract can help supplement retirement income through the annuitization feature, which provides a stream of periodic income payments. During the years leading up to those income payments, the Contract Ownermanages his/her assets in the contract according to their specific goals and risk preferences by directing the allocation and reallocation among a variety of investment options. Contract growth is tax-deferred, meaning that gains in the contract are not taxable until withdrawn from the contract. Finally, in the event that the Annuitant dies before beginning income payments, the contract offers a death benefit.

Prospective purchasers should consult with a financial professional to determine whether this contract is appropriate for them, taking into consideration their particular needs, including investment objectives, risk tolerance, investment time horizon, marital status, tax situation, and other personal characteristics. Generally speaking, this contract is intended to provide benefits to a single individual and his/her beneficiaries. The contract is not intended to be used by institutional investors, in connection with other Nationwide contracts that have the same Annuitant, or in connection with other Nationwide contracts that have different Annuitants but the same Contract Owner. It is not intended to be sold to a terminally ill Contract Owner or Annuitant.

If the Contract Owner elects to pay the investment advisory fees from the Contract Value, this may reduce the death benefit and other benefits under the contract, may be subject to federal and state income taxes, and may be subject to a 10% federal tax penalty (see Charges and Deductions, Surrender/Withdrawal Prior to Annuitization, and Appendix C: Contract Types and Tax Information in the statutory prospectus).

Phases of the Contract

The contract exists in two separate phases: accumulation (savings) and annuitization (income). During the accumulation phase, the contract offers a variety of investment options to which the Contract Owner can allocate and reallocate his/her Contract Value. The investment options available under the contract consist of Sub-Accounts that invest in underlying mutual funds, which offer a variable rate of return. Additional information about the underlying mutual funds is available in Appendix: Underlying Mutual Funds Available Under the Contract.

During the annuitization phase, Nationwide makes periodic income payments to the Annuitant. At the time of annuitization, the Annuitant elects the duration of the annuity payments - either for a fixed period of time or for the duration of the Annuitant's (and possibly the Annuitant's spouse's) life. Annuity payments are fixed, meaning each annuity payment will be the same amount. After annuitization begins, the only value associated with the contract is the stream of annuity payments; unless otherwise specified in the annuity option, the Annuitant cannot withdraw value from the contract over and above the annuity payments. Additionally, once annuitization has begun, there is no death benefit, which means that upon the death of the Annuitant (and the Annuitant's spouse if a joint annuity option was elected), all payments stop and the contract terminates, unless the particular annuitization option provides otherwise.

Contract Features

Investment Options.Contract Owners can allocate Contract Value to Sub-Accounts that invest in underlying mutual funds. Contract Owners can reallocate those assets at their discretion, subject to certain restrictions.

Deposits to the Contract.Contract Owners can apply additional purchase payments to the contract until the Annuitization Date, subject to certain restrictions.

Withdrawals from the Contract.Contract Owners can withdraw some or all of their Contract Value at any time prior to annuitization, subject to certain restrictions. After Annuitization, withdrawals other than annuity payments are not permitted.

Death Benefit. During the accumulation phase, the contract contains a standard death benefit (return of Contract Value) at no additional charge.

Optional Death Benefit. A death benefit option is available for an additional charge, which may provide a greater death benefit than the standard death benefit. The optional death benefit is:

Spousal Protection Feature. The death benefit option contains the Spousal Protection Feature, which allows a surviving spouse to continue the contract while receiving the economic benefit of the death benefit upon the death of the other spouse, subject to certain conditions.

Terminal Illness Surrender Benefit. The death benefit option contains the Enhanced Surrender Value for Terminal Illness feature. Under this feature, if after the first Contract Anniversary, the Contract Owner/ Annuitant (or Co-Annuitant, if applicable) is terminally ill and the Contract Owner fully surrenders the Contract, Nationwide will pay the Contract Valueplus any additional amount necessary to equal the optional death benefit, subject to certain conditions.

Living Benefit Options. Several living benefit options are available for an additional charge, which provide a guaranteed lifetime income stream for the Contract Owner and, if elected, the Contract Owner's spouse. Those options are:

Annuity Payments. On the Annuitization Date, Nationwide will make annuity payments based on the annuity payment option chosen prior to annuitization.

Tax Deferral. Generally, Contract Owners will not be taxed on any earnings on the assets in the contract until such earnings are distributed from the contract. How each contract's distributions are taxed depends on the type of contract issued. Note that if this contract is issued in connection with a plan that qualifies for special income tax treatment under the Code, the contract does not provide additional tax deferral benefits (see Appendix C: Contract Types and Tax Information in the statutory prospectus).

Cancellation of the Contract. Under state insurance laws, Contract Owners have the right, during a limited period of time, to examine their contract and decide if they want to keep it or cancel it. Nationwide will honor any free look cancellation request that is in good order and received at the Service Center or postmarked within 30 days after the contract issue date (see Right to Examine and Cancel and Contacting the Service Center in the statutory prospectus).

Contract Owner Services. The contract offers several services at no additional charge to assist Contract Owners in managing their contract, including:

Buying the Contract

Minimum Initial and Subsequent Purchase Payments

All purchase payments must be paid in the currency of the United States of America. The minimum initial purchase payment is $25,000. The minimum subsequent purchase payment is $1,000.However, for subsequent purchase payments sent via electronic deposit, the minimum subsequent purchase payment is $150.

Some states have different minimum initial and subsequent purchase payment amounts, and subsequent purchase payments may not be permitted in all states. See Appendix B: State Variations in the statutory prospectus for information on subsequent purchase payment requirements in a particular state.

Some optional benefits may restrict the Contract Owner's ability to make subsequent purchase payments (see Dollar Limit Restrictions).

Nationwide reserves the right to refuse any purchase payment that would result in the cumulative total for all contracts issued by Nationwide or its affiliates or subsidiaries on the life of any one Annuitant or owned by any one Contract Owner to exceed $1,000,000.Its decision as to whether or not to accept a purchase payment in excess of that amount will be based on one or more factors, including, but not limited to: age, spouse age (if applicable), Annuitantage, state of issue, total purchase payments, optional benefits elected, current market conditions, and current hedging costs. All such decisions will be based on internally established actuarial guidelines and will be applied in a non-discriminatory manner. In the event that Nationwide does not accept a purchase payment under these guidelines, the purchase payment will be immediately returned in its entirety in the same manner as it was received. If Nationwide

accepts the purchase payment, it will be applied to the contract immediately and will receive the next calculated Accumulation Unit value.Any references in this prospectus to purchase payment amounts in excess of $1,000,000 are assumed to have been approved by Nationwide.

Nationwide prohibits subsequent purchase payments made after death of the Contract Owner(s), the Annuitant, or Co-Annuitant. If upon notification of death of the Contract Owner(s), the Annuitant, or Co-Annuitant, it is determined that death occurred prior to a subsequent purchase payment being made, Nationwide reserves the right to return the purchase payment.

Dollar Limit Restrictions

Certain features of the contract have additional purchase payment and/or Contract Value limitations associated with them:

Annuitization. Annuity payment options will be limited if the Contract Owner submits total purchase payments in excess of $2,000,000. Furthermore, if the amount to be annuitized is greater than $5,000,000, Nationwide may limit both the amount that can be annuitized on a single life and the annuity payment options (see Annuity Payment Options in the statutory prospectus).

Death Benefit Calculations. Purchase payments up to $3,000,000 may result in a higher death benefit payment than purchase payments in excess of $3,000,000 (see Death Benefit Calculations in the statutory prospectus).

Subsequent Purchase Payments. If the Contract Owner elects the Nationwide Lifetime Income Rider Plus Core Advisory, Nationwide Lifetime Income Rider Plus Accelerated Advisory, or the Pro 4 option, Nationwide reserves the right to refuse any subsequent purchase payments. Contract Owners should consider this reservation of right when making the initial purchase payment.

Application of Purchase Payments

Initial Purchase Payments

Initial purchase payments will be priced at the Accumulation Unit value next determined no later than two business days after receipt of an order to purchase if the application and all necessary information are complete and are received at the Service Center before the close of regular trading on the New York Stock Exchange, which generally occurs at 4:00 p.m. EST. If the order is received after the close of regular trading on the New York Stock Exchange, the initial purchase payment will be priced within two business days after the next Valuation Date.

If an incomplete application is not completed within five business days after receipt at the Service Center, the prospective purchaser will be informed of the reason for the delay. The purchase payment will be returned unless the prospective purchaser specifically consents to allow Nationwide to hold the purchase payment until the application is completed.

Subsequent Purchase Payments

Any subsequent purchase payment received at the Service Center (along with all necessary information) before the close of regular trading on the New York Stock Exchange on any Valuation Date will be priced at the Accumulation Unit value next determined after receipt of the purchase payment. If a subsequent purchase payment is received at the Service Center (along with all necessary information) after the close of regular trading on the New York Stock Exchange, it will be priced at the Accumulation Unit value determined on the following Valuation Date.

Making Withdrawals: Accessing the Money in Your Contract

Surrender/Withdrawal Prior to Annuitization

Prior to annuitization and before the Annuitant's death, Contract Owners may generally withdraw some or all of their Contract Value. Withdrawals from the contract may be subject to federal income tax and/or a tax penalty (see Appendix C: Contract Types and Tax Information in the statutory prospectus). Withdrawal requests may be submitted in writing or by telephone to the Service Center and Nationwide may require additional information. Requests submitted by telephone may be subject to dollar amount limitations and may be subject to payment and other restrictions to prevent fraud. Nationwide reserves the right to require written requests to be submitted on current Nationwide forms for withdrawals. Nationwide reserves the right to remove the ability to submit requests by telephone upon written or electronic notice. Contact the Service Center for current limitations and restrictions. When taking a full surrender, Nationwide may require that the contract accompany the request. Nationwide may require a signature guarantee.

Surrender and withdrawal requests will receive the Accumulation Unit value next determined at the end of the current Valuation Period if the request and all necessary information is received at the Service Center before the close of regular trading on the New York Stock Exchange (generally, 4:00 pm EST). If the request and all necessary information is received after the close of regular trading on the New York Stock Exchange, the request will receive the Accumulation Unitvalue determined at the end of the next Valuation Day.

Nationwide will pay any amounts withdrawn from the Sub-Accounts within seven days after the request is received in good order at the Service Center (see Determining the Contract Value in the statutory prospectus). However, Nationwide may suspend or postpone payment when it is unable to price a purchase payment or transfer, or as permitted or required by federal securities laws and rules and regulations of the SEC.

Surrender/Withdrawal After Annuitization

After the Annuitization Date, withdrawals other than regularly scheduled annuity payments are not permitted.

The following tables describe the fees and expenses that a Contract Owner will pay when buying, owning, and surrendering or making withdrawals from the contract. Please refer to the contract specifications page for information about the specific fees the Contract Owner will pay each year based on the options elected.

Income Benefit Investment Options

Certain optional benefits restrict how the Contract Owner can invest their Contract Value by limiting the investment options in which the Contract Owner can invest and/or requiring use of a specified asset allocation service. The investment options available under each optional living benefit are chosen by Nationwide based on each investment option's risk characteristics. The permitted investment options are more conservative than those that are not permitted. This helps Nationwide manage its obligation to provide Contract Owners with Lifetime Withdrawals by reducing the likelihood that it will have to make unanticipated payments. By electing an optional living benefit and accepting the limited menu of investment options, Contract Owners may be foregoing investment gains that could otherwise be realized by investing in riskier investment options that are not available under the optional living benefit. Only the investment options shown below (and designated by an "X") are available in connection with the respective optional benefit.
