APPENDIX A—Accumulation Unit Values			22

 

Unless otherwise specified in this prospectus, the words “Northwestern Mutual,” “we,” “us,” “our,” and “Company” mean The Northwestern Mutual Life Insurance Company. The words “you” and “your,” unless otherwise specified, mean the Contract Owner. We use a number of special terms in this prospectus, including the following:

Accumulation Unit—An accounting unit of measure representing the Contract Value, before the date on which Annuity Payments begin, in one or more Divisions of the Separate Account. The related term “Accumulation Unit Value” means the value of a particular Accumulation Unit at a particular time and is analogous to, but not the same as, the share price of a mutual fund.

Annuitant—The person upon whose life the Contract is issued and Contract benefits depend. The Primary Annuitant is the person upon whose life the Contract is initially issued. The Contingent Annuitant is the person who becomes the Annuitant upon the death of the Primary Annuitant. If the Contract is annuitized under a single life income plan, there will be one Annuitant. If the Contract is annuitized under a joint life income plan, there will be two Joint Annuitants.

Annuity Payments—Money we pay pursuant to the terms of the Contract. Payments may be paid under one or more of the following three methods: (1) a variable income plan; (2) a fixed income plan; or (3) in cash.

Annuity Unit—An accounting unit of measure representing the actuarial value of a variable income plan’s interest in a Division of the Separate Account after Annuity Payments begin.

Beneficiary—A person who receives payments under the Contract upon the death of the Annuitant before the Maturity Date provided that the Annuitant was an Owner of the Contract at the time of death.

Contract—The agreement between you and us described in this variable annuity prospectus. During the Accumulation Period of the Contract, you may invest money under your contract and any earnings on your investment will accumulate on a tax-deferred basis. During the Annuitization Period, you receive periodic payments based largely on the amounts you accumulate, all or a portion of which will be taxable as ordinary income.

Contract Value—The value of your Contract on any Valuation Date is the sum of: (1) the value of your amounts held in the Divisions of the Separate Account on that Valuation Date; less (2) any withdrawals since that Valuation Date and any applicable charges under the Contract deducted since that Valuation Date.

Division—A sub-account of the Separate Account, the assets of which are invested exclusively in the shares of one of the Portfolios of the underlying Funds.

Fund—A Fund is registered under the Investment Company Act of 1940 (the “1940 Act”) as an open-end management investment company or as a unit investment trust, or is not required to be registered under the Act. A Fund is available as an investment option under the Contract. The assets of each of the Divisions of the Separate Account are used to purchase shares of the corresponding Portfolio of a Fund.

General Account—All assets of the Company, other than those held in the Separate Account or in other separate accounts that have been or may be established by the Company.

Income Plan— An optional method of receiving the death benefit, maturity benefit, surrender proceeds or withdrawal proceeds of an insurance policy or annuity contract through a series of periodic payments. An Income Plan may also be known as a “payment plan”.

Maturity Date—The date, stated on the specifications page of the Contract, on which Purchase Payments cease and Annuity Payments become payable.

Owner—The person with the sole right to exercise all rights and privileges under the Contract, except as the Contract otherwise provides.

Portfolio—A series of a Fund available for investment under the Contract which corresponds to a particular Division of the Separate Account.

Purchase Payments—Money you give us to apply to your Contract. The related term “Net Purchase Payment” refers to Purchase Payments after all applicable deductions.

Required Minimum Distribution (“RMD”)—A minimum amount that federal tax law generally requires be withdrawn from certain tax-qualified annuities each year.

Separate Account—The account the Company has established pursuant to Wisconsin law for those assets, although belonging to the Company, that are reserved for you and other owners of variable annuity contracts supported by the Separate Account.

Valuation Date—Any day on which the New York Stock Exchange (“NYSE”) is open for trading and any other day we are required under the 1940 Act to value assets of a Division of the Separate Account.

The value of an Accumulation Unit is determined on the basis of changes in the per share value of the underlying Portfolios and the assessment of Separate Account charges, which may vary from contract to contract. (For more information on the

calculation of underlying account values, see “Application of Purchase Payments.”) Please refer to Appendix A of this prospectus for information regarding the historical Accumulation Unit Values.

 

Financial statements of the Separate Account and the financial statements of Northwestern Mutual appear in the Statement of Additional Information (“SAI”). The financial statements of the Company should only be considered with respect to the Company’s ability to meet its obligations under the Contract and not with respect to the Contract Value held in the Separate Account, which is principally derived from the investment performance of the Portfolios. The SAI is available free of charge at www.northwesternmutual.com. To receive a copy of the SAI, send a written request to Northwestern Mutual, Risk Products Department, Room T22, 720 East Wisconsin

Avenue, Milwaukee, WI 53202, or use the coupon provided at the back of this Prospectus. Semiannually, we will send you reports containing financial information and schedules of investments for the Portfolios underlying the Divisions in which you invest. We will also send you periodic statements showing the value of your Contract and transactions under the Contract since the last statement. You should promptly review these statements and any confirmations of individual transactions that you receive to verify the accuracy of the information, and should promptly notify us of any discrepancies.

 

The Northwestern Mutual Life Insurance Company, or through its subsidiaries and affiliates, offers insurance products, investment products, and advisory services which are designed to address clients’ needs for financial security and protection, wealth accumulation and distribution, and estate preservation. Organized by a special act of the Wisconsin Legislature in 1857, the Company is licensed to conduct a conventional life insurance business in the District of Columbia and in all states of the United States. The Company’s total assets were over $290 billion as of December 31, 2019. The Home Office of Northwestern Mutual is located at 720 East Wisconsin Avenue, Milwaukee, Wisconsin 53202.

In addition to your fixed account allocations, General Account assets are used to guarantee the payment of certain benefits under the Contracts, including death benefits. To the extent that we are required to pay you amounts in addition to your

Contract Value under these benefits, such amounts will come from General Account assets. Thus, Contract Owners must look to the strength of the Company and its General Account with regard to insurance contract guarantees. You should also be aware that the General Account is exposed to the risks normally associated with the operation of a life insurance company, including insurance pricing, asset liability management and interest rate risk, operational risks, and the investment risks of a portfolio of securities that consists largely, though not exclusively, of fixed-income securities. Some of the risks associated with such a portfolio include interest rate, option, liquidity, and credit risk. The financial statements contained in the Statement of Additional Information include a further discussion of risks inherent within the General Account investments. The assets in the General Account are subject to the claims of the Company’s general creditors.

 

We established the NML Variable Annuity Account C (the “Separate Account”) on July 22, 1970 by action of our Board of Trustees in accordance with the provisions of the Wisconsin insurance law. The Separate Account is registered with the SEC as a unit investment trust under the 1940 Act.

You may allocate the money you invest under your Contract among the Divisions each of which corresponds to one of the Portfolios of the Funds. The Divisions and Portfolios are described elsewhere in this prospectus. Under Wisconsin law, the investment operations of the Separate Account are kept separate from our other operations. The values for your Contract supported by the Separate Account will not be affected by income, gains, or losses from the rest of our business. The income, gains or losses, realized or unrealized, for the assets we place in the Separate Account for your Contract will determine the value of your Contract benefits supported by the Separate Account, and will not affect the rest of our business. The assets in the Separate Account are reserved for you and other owners of variable annuity contracts, although the assets belong to us and we do not hold the assets as a trustee. While we and our creditors cannot

reach the assets of the Separate Account to satisfy other obligations until our obligations under your Contract have been satisfied, all of our assets (except those we hold in certain other separate accounts) are available to satisfy our obligations under your Contract. The obligations under the variable annuity contracts are obligations of the Company as depositor.

When permitted by law and subject to any required regulatory approvals or votes by Contract Owners we reserve the right to:

 

•

Operate the Separate Account or a Division as either a unit investment trust or a management company under the 1940 Act, or in any other form allowed by law, if deemed by the Company to be in the best interest of Contract Owners.

 

•

Invest current and future assets of a Division in securities of another Portfolio as a substitute for shares of a Portfolio (or another share class of an existing Portfolio) already purchased or to be purchased.

 

•

Register or deregister the Separate Account under the 1940 Act or change its classification under that Act.

 

•

Create new separate accounts.

 

•

Combine the Separate Account with any other separate account.

 

•

Transfer the assets and liabilities of the Separate Account to another separate account.

 

•

Transfer cash from time to time between the Company’s general account and the Separate Account as deemed necessary or appropriate and consistent with the terms of the Contracts, including but not limited to transfers for the deduction of charges and in support of payment options.

 

•

On behalf of the Company, transfer assets of the Separate Account in excess of reserve requirements (only for accrued fees and charges or any seed capital) applicable to Contracts supported by the Separate Account to the Company’s General Account.

•

Add, delete or make changes to the securities and other assets that are held or purchased by the Separate Account.

 

•

Terminate and/or liquidate the Separate Account.

 

•

Restrict or eliminate any voting rights of Contract Owners or other persons who have voting rights as to the Separate Account.

 

•

Make any changes to the Separate Account to conform with, or required by any change in, federal tax law, the 1940 Act and regulations promulgated thereunder, or any other applicable federal or state laws.

In the event that we take any of these actions, we may make an appropriate endorsement of your Contract and take other actions to carry out what we have done.

 

The Contract makes available a variety of variable investment options. The Company does not endorse or recommend any particular option nor does it provide asset allocation or investment advice. You are responsible for choosing your investment options and the amounts you allocate to each based on your individual situation and your personal savings goals and risk tolerances. After your initial investment decision, you should monitor your investments and periodically review the options you select and the amount allocated to each option to ensure your decisions continue to be appropriate. The amounts you invest are not guaranteed and, because both your principal and any return on your investment are subject to market risk, you can lose money.

Each Division of the Separate Account represents an investment option and its assets are invested in a corresponding Portfolio that is a series of one of the following mutual fund families: Northwestern Mutual Series Fund, Inc.; Fidelity^® Variable Insurance Products; Neuberger Berman Advisers Management Trust; the Russell Investment Funds; and the Credit Suisse Trust. The Separate Account buys shares of the Portfolios at their respective net asset values without sales charge. The Portfolios are available for investment only by separate accounts supporting variable insurance products and are not publicly traded. Their performance can differ substantially from publicly traded mutual funds with similar names. The specific Portfolios available under your Contract may change from time to time, and not all Portfolios in which assets of the Separate Account are invested may be available under your Contract. Your ability to invest in a Portfolio may be affected by the actions of such Portfolio, such as when a Portfolio closes.

You may choose to allocate the Accumulation Value of your Contract among the Divisions and you may, subject to certain conditions, transfer values from one Division to another. Amounts you allocate among the Divisions may grow in

value, decline in value, or grow less than you expect, depending on the investment performance of the corresponding Portfolio. The investment objectives and types of investments for each Portfolio are set forth below. There can be no assurance that the Portfolios will realize their objectives. For more information about the investment objectives and policies, the attendant risk factors and expenses for each of the Portfolios described below, see the attached prospectuses. Read the prospectuses carefully before you invest. Please see the prospectuses for the Funds for a discussion of the potential risks and conflicts presented by the use of a Fund as an investment option under variable annuity contracts and variable life insurance policies offered by affiliated and non-affiliated life insurance companies. Note: If you received a summary prospectus for a portfolio listed below, please follow the directions on the first page of the summary prospectus to obtain a copy of the full fund prospectus.

Northwestern Mutual Series Fund, Inc.    The principal investment adviser for the Portfolios of the Northwestern Mutual Series Fund is Mason Street Advisors, LLC (“MSA”), our wholly-owned company. The investment advisory agreements for the respective Portfolios provide that MSA will provide services and bear certain expenses of the Portfolios. MSA employs a staff of investment professionals to manage the assets of the Fund and the other advisory clients of MSA. We provide related facilities and personnel, which MSA uses in performing its investment advisory functions. MSA has retained and oversees a number of asset management firms under investment sub-advisory agreements to provide day-to-day management of the Portfolios indicated below. Each such sub-adviser may be replaced without the approval of shareholders. Please see the attached prospectuses for the Northwestern Mutual Series Fund, Inc. for more information.

 

Payments We Receive    The Contract makes available both proprietary and non-proprietary Portfolios. The Northwestern Mutual Series Fund, Inc. is a proprietary Fund that has been included in part because it is managed by a subsidiary of the Company. For non-proprietary Portfolios offered through this Contract, we consider during the selection process whether the Portfolio’s investment adviser or an affiliate will make payments to us or our affiliates. Other factors we consider during the selection process include asset class coverage, management style, sector coverage, the strength of the investment adviser’s or sub-advisers’ reputation and tenure, brand recognition, performance, and the capability and qualification of each investment firm. We review the Portfolios periodically and may remove a Portfolio or limit its availability to new premiums and/or transfers of Contract Value if we

determine that the Portfolio no longer meets one or more of the selection criteria, and/or if the Portfolio has not attracted significant allocations from Owners.

We do not provide any investment advice and do not recommend or endorse any particular Portfolio. You bear the risk of any decline in the Contract Value of your Contract resulting from the performance of the Portfolio you have chosen.

Owners, through their indirect investment in the Portfolios, bear the costs of the investment advisory or management fees that the Portfolios pay to their respective investment advisors (see the Portfolios’ prospectuses for more information). As described above, an investment adviser of a Portfolio, or its affiliates, may make payments to the Company and/or certain

 

of our affiliates. However, the amount of such payments is not determinative as to whether a Portfolio is offered through the Contract. These payments may be derived, in whole or in part, from the advisory fee deducted from Portfolio assets. The amount of the compensation is based on a percentage of assets of the Portfolios attributable to the Contracts and certain other variable insurance products that the Company issues. The percentages differ and some investment advisers (or other affiliates) may pay more than others. The percentages currently range up to 0.25%. These payments are made for various purposes, including payment of services incurred by the Company and/or its affiliates in promoting and marketing of the Contracts and Portfolios. The Company and its affiliates may profit from these payments.

While not currently the case, certain Portfolios available under the Policy may adopt a Distribution (and/or Shareholder Servicing) Plan under Rule 12b-1 of the 1940 Act, which is described in more detail in the Portfolios’ prospectuses. These payments, which may be up to 0.25%, would be deducted from assets of the Portfolios and are paid to our distributor, Northwestern Mutual Investment Services, LLC. These payments would decrease such Portfolio’s investment return. We would also consider the receipt of these payments generally to be a positive factor when selecting Portfolios.

Additionally, an investment adviser of a Portfolio or its affiliates may provide the Company with wholesaling services that assist in the distribution of the Contracts and may pay the Company and/or certain of our affiliates amounts to participate in sales meetings. These amounts may be significant and may provide the investment adviser (or its affiliate) with increased access to persons involved in the distribution of the Contracts.

Transfers Between Divisions    Subject to the short term and excessive trading limitations described below and any frequent trading policies adopted by the Funds that are described in their prospectuses, you may change the allocation of Purchase Payments among the Divisions and transfer values from one Division to another both before and after Annuity Payments begin. In order to take full advantage of these features you should carefully consider, on a continuing basis, which investment options are best suited to your long-term investment needs. See “Owner Inquiries and Instructions” for more information on how you may change the allocation of Accumulation or Annuity Units among the Divisions.

We will make the transfer based upon the next valuation of Accumulation or Annuity Units in the affected Divisions after our receipt of your request for transfer at our Home Office, provided it is in good order. If we receive your request for transfer before the close of trading on the NYSE (typically, 4:00 p.m. Eastern Time), your request will receive same-day pricing. If we receive your request for transfer on or after the close of trading on the NYSE, we will process the order using the value of the units in the Divisions determined at the close of the next regular trading session of the NYSE. We will adjust the number of such units to be credited to reflect the respective value of the units in each of the Divisions. The minimum amount of Accumulation Units which may be transferred is the lesser of $100 or the entire value of the Accumulation Units in the

Division from which the transfer is being made. There is no minimum transfer amount for Annuity Units.

Short Term and Excessive Trading    Short term and excessive trading (sometimes referred to as “market timing”) may present risks to a Portfolio’s long-term investors, such as Owners and other persons who may have material rights under the Contract (e.g., beneficiaries), because it can, among other things, disrupt Portfolio investment strategies, increase Portfolio transaction and administrative costs, require higher than normal levels of cash reserves to fund unusually large or unexpected redemptions, and adversely affect investment performance. These risks may be greater for Portfolios that invest in securities that may be more vulnerable to arbitrage trading including foreign securities and thinly traded securities, such as small cap stocks and non-investment grade bonds. These types of trading activities also may dilute the value of long-term investors’ interests in a Portfolio if it calculates its net asset value using closing prices that are no longer accurate. Accordingly, we discourage market timing activities.

To deter short term and excessive trading, we have adopted and implemented policies and procedures which are designed to control abusive trading practices. We seek to apply these policies and procedures uniformly to all Contract Owners. Any exceptions must be either expressly permitted by our policies and procedures or subject to an approval process described in them. We may also be prevented from uniformly applying these policies and procedures under applicable state or federal law or regulation. Because exceptions are permitted, it is possible that investors may be treated differently and, as a result, some may be allowed to engage in trading activity that might be viewed as market timing.

Among the steps we have taken to reduce the frequency and effect of these practices are monitoring trading activity and imposing trading restrictions including the prohibition of more than twelve transfers among Divisions under a single Contract during a Contract year. Multiple transfers with the same effective date made by the same Owner will be counted as a single transfer for purposes of applying the twelve transfer limitation. Further, an investor who is identified as having made a transfer in and out of the same Division, excluding the Government Money Market Division, (“round trip transfer”) in an amount in excess of $10,000 within fourteen calendar days will be restricted from making additional transfers after making two or more such round trip transfers within any Contract year, including the year in which the first such round trip transfer was made. The restriction will last until the next Contract anniversary date and the Contract Owner will be sent a letter informing him or her of the restriction. An investor who is identified as having made one round trip transfer within thirty calendar days aggregating more than one percent (1%) of the total assets of the Portfolio underlying a Division, excluding the Government Money Market Division and the Divisions corresponding to the Portfolios of the Russell Investment Funds LifePoints^® Variable Target Portfolio Series, will be restricted from making additional transfers after making one more such round trip transfer within any Contract

 

year, including the year in which the first such round trip transfer was made. The restriction will last until the next Contract anniversary date and the Contract Owner will be sent a letter informing him or her of the restriction. Unless we believe your trading behavior to be inconsistent with these short-term and excessive trading policies, these limitations will not apply to automatic asset transfers, scheduled or systematic transactions involving portfolio rebalancing, dollar cost averaging, interest sweeps, or to initial allocations or changes in future allocations, to the extent these features are available in your Contract. Once a Contract is restricted, we will allow one additional transfer into the Government Money Market Division until the next Contract anniversary. Additionally, in accordance with our procedures, we may modify some of these limitations to allow for transfers that would not count against the total transfer limit but only as necessary to alleviate any potential hardships to Owners (e.g., in situations involving a substitution of an underlying fund).

We may change these policies and procedures from time to time in our sole discretion without notice; provided, however, Contract Owners will be given advance, written notice if the policies and procedures are revised to accommodate market timing. Additionally, the Funds may have their own policies and procedures described in their prospectuses that are designed to limit or restrict frequent trading. Such policies may be different from our policies and procedures, and may be more or less restrictive. As the Funds may accept purchase payments from other investors, including other insurance company separate accounts on behalf of their variable product customers and retirement plans, we cannot guarantee that Funds will not be harmed by any abusive market timing activity relating to the retirement plans and/or other insurance companies that may invest in the Funds. Such policies and

procedures may provide for the imposition of a redemption fee and, upon request from the Fund, require us to provide transaction information to the Fund (including an Owner’s tax identification number) and to restrict or prohibit transfers and other transactions that involve the purchase of shares of a Portfolio(s). In the event a Fund instructs us to restrict or prohibit transfers or other transactions involving shares of a Portfolio, you may not be able to make additional purchases in an investment option until the restriction or prohibition ends. If you submit a request that includes a purchase or transfer into such a restricted investment option, we will consider the request “not in good order” and it will not be processed. You may, however, submit a new transfer request.

If we believe your trading activity is in violation of, or inconsistent with, our policies and procedures or otherwise is potentially disruptive to the interests of other investors, you may be asked to stop such activities and future investments, and allocations or transfers by you may be rejected without prior notice. Because we retain discretion to determine what action is appropriate in a given situation, investors may be treated differently and some may be allowed to engage in activities that might be viewed as market timing.

We intend to monitor events and the effectiveness of our policies and procedures in order to identify whether instances of potentially abusive trading practices are occurring. However, we may not be able to identify all instances of abusive trading practices, nor completely eliminate the possibility of such activities, and there may be technological limitations on our ability to impose restrictions on the trading practices of Contract Owners. We may be unable to monitor trading activity by individual participants in omnibus accounts established under group annuity contracts.

 

Generally    The Contract is intended for retirement and long-term savings. The Contract provides for a death benefit during the years when funds are being accumulated and for a variety of income options following retirement. During the years when funds are being paid into your Contract, known as the accumulation phase, the earnings accumulate on a tax-deferred basis. The earnings are subject to tax as ordinary income if you make a withdrawal. The income phase begins when you start receiving Annuity Payments under your Contract. Monthly Annuity Payments begin on the date you select. The amount you accumulate under your Contract, including the results of investment performance, will determine the amount of your monthly Annuity Payments. If, however, the Contract is owned by a non-natural person (e.g., a corporation or a trust), the tax deferral on earnings may be lost. While there are exceptions for certain employee benefit plans, any income on a Contract owned by a non-natural person will generally be treated as ordinary income subject to annual taxation.

If you are purchasing the Contract through a tax-favored arrangement, including IRAs and Roth IRAs, you should carefully consider the costs and benefits of the Contract before purchasing the Contract, since the tax-favored arrangement itself provides for tax-sheltered growth. Certain provisions of the Contract may be different than the general description in this prospectus, and certain riders, options, or funds may not be available because of legal restrictions in your state. You should consult your Contract, as any such state variations will be included in your Contract or in riders or endorsements attached to your Contract.

Eligible Purchasers    Pursuant to a determination of eligibility by an officer of Northwestern Mutual Investment Services, LLC (“NMIS”), principal underwriter and distributor of the Contract, or by his or her designee, Contracts may be sold to current or retired registered representatives of NMIS, immediate family members of such registered representatives, a family trust in the name of such a registered representative, or individuals directly employed by current representatives (“Eligible Persons”). For this purpose,

 

“immediate family” means (a) current spouses (or spousal equivalents if recognized under local law), or (b) parents and children (under age 21), including parents and children in adoptive and current step relationships. After a Contract is purchased, additional investments can be made for the life of the Contract regardless of the eligibility status of the purchaser.

Free Look    If you return the Contract within ten days after you receive it (or whatever period is required under applicable state law), we will send your money back. There is no charge for our expenses but the amount you receive may be more or less than what you paid, based on actual investment experience following the date we received your purchase payment. In the event that applicable state law requires us to return the full amount of your purchase payment, we will do so.

Contract Values    The value of your Contract on any Valuation Date is the sum of the following: (i) the value of your amounts held in the Divisions of the Separate Account on that Valuation Date; less (ii) any withdrawals since that Valuation Date and any applicable charges under the Contract deducted since that Valuation Date. We use the “net investment factor” as a way to calculate the investment performance of a Division from valuation period to valuation period. For each Division, the net investment factor shows the investment performance of the underlying mutual fund Portfolio in which a particular Division invests, including the charges assessed against that Division for a given valuation period. The Portfolios will distribute investment income and realized capital gains to the Divisions, which we will reinvest in additional shares of those same Portfolios. Unrealized capital gains and realized and unrealized capital losses will be reflected by changes in the value of the shares held by the Division. We may surrender your Contract for its Contract Value, in accordance with applicable state law, if, before the Maturity Date no Purchase Payments have been received under the Contract for a period of two full years and both the Contract Value and the total Purchase Payments paid (less amounts withdrawn) are each less than $2,000.

Purchase Payments Under the Contract

Frequency and Amount    A Purchase Payment is the money you give us to apply to your Contract. You may make Purchase Payments monthly, quarterly, semiannually, annually, or on any other frequency acceptable to us. The minimum initial Purchase Payment is $10,000. The minimum amount for each subsequent Purchase Payment is $25, although we may accept lower amounts in certain circumstances. We will accept larger Purchase Payments than the minimums, but total Purchase Payments under any Contract may not exceed $5,000,000 without our consent.

In certain situations, we may, in our discretion, reduce or waive our minimum purchase payment requirements. For example, we may reduce the minimum initial purchase amount from $10,000 to no less than $5,000 provided you elect on your application to make additional subsequent Purchase Payments such that the total Purchase Payments you

make on or before the first anniversary date of your Contract equal or exceed $10,000. Also, when initial Purchase Payments representing proceeds from annuity exchanges are determined to satisfy the Contract minimum based on values at the time you sign your application, but the amount subsequently received by us is less than the required minimum due to market value fluctuations and sales or administrative fees charged in connection with the exchange, we may reduce the required minimum by the sum of any such depreciation and fees.

Application of Purchase Payments    We credit Net Purchase Payments to the variable options as you direct, and invest those assets in shares of those Portfolios that correspond to the applicable Divisions; the term “Accumulation Units” describes the value of this interest in the Separate Account.

Initial Net Purchase Payments allocated to a Division will be priced at the Accumulation Unit Value determined no later than two Valuation Dates after we receive at our Home Office or a lockbox facility we have designated both your initial Purchase Payment and your application in good order. “Good order” means that the application is complete and accurate and all applicable requirements are satisfied. If your application is not in good order, we may take up to five Valuation Dates to resolve the problem. If we are unable to resolve the problem within that time, we will notify you in writing of the reasons for the delay. If you revoke the consent given with your application to hold your initial Purchase Payment pending resolution of the problem, we will return your payment. Otherwise, the number of Accumulation Units you receive for your initial Net Purchase Payment will be determined based upon the valuation of the assets of that Division we make not later than two Valuation Dates following the date on which the problem is resolved and your application is put into good order. Although we do not anticipate delays in our receipt and processing of applications or Purchase Payment requests, we may experience such delays to the extent applications and Purchase Payments are not forwarded to our Home Office in a timely manner. Such delays could result in delays in the issuance of Contracts and the allocation of Purchase Payments under existing Contracts.

Subsequent Net Purchase Payments will be priced based on the next determined Accumulation Unit Value after the payment is received in good order either at the Home Office or a lockbox facility we have designated.

We deem receipt of a Purchase Payment to occur on a given Valuation Date if receipt occurs before the close of trading on the NYSE (typically, 4:00 p.m. Eastern Time). If receipt occurs on or after the close of trading on the NYSE, we deem receipt to occur on the following Valuation Date. You may send Purchase Payments to our Home Office or to a payment center designated by us. All payments must be made in U.S. Dollars payable through a U.S. financial institution. We accept Purchase Payments by check or electronic funds transfer (“EFT”). We do not accept third-party checks at the Home Office as part of the initial Purchase Payment. We generally will not accept cash, money orders, traveler’s checks, or “starter” checks; however, in limited circumstances, we may

 

accept some cash equivalents in accord with our anti-money laundering procedures. If you make a Purchase Payment with a check or bank draft and, for whatever reason, it is later returned unpaid or uncollected, or if a Purchase Payment by EFT is reversed, we reserve the right to reverse the transaction. We also reserve the right to recover any resulting losses incurred by us by withdrawing a sufficient amount of Contract Value. We may reject any application or Purchase Payment for any reason permitted by law. We may also be required to provide additional information about you and your account to government regulators.

The value of an Accumulation Unit in each Division varies with the investment experience of the Division (which in turn is determined by the investment experience of the corresponding Portfolio). We determine the value by multiplying the value on the immediately preceding valuation date by the net investment factor for the Division. The net investment factor takes into account the investment experience of the Portfolio, the deduction for mortality and expense risks we have assumed and a deduction for any applicable taxes or for any expenses resulting from a substitution of securities. Since you bear the investment risk, there is no guarantee as to the aggregate value of your Accumulation Units. That value may be less than, equal to, or more than the cumulative net purchase payments you have made.

Maturity Date    Under Contracts currently offered, Purchase Payments may be made until the Maturity Date stated on the Contract’s specifications page, or until Annuity Payments begin, whichever is earlier. Distributions may be required before the Maturity Date. (See “Taxation of Contract Benefits.”) Any death benefit you elect will automatically terminate upon annuitization, which will occur no later than the contract’s maturity date (i.e., the date upon which you must either annuitize or take a lump sum).

Access to Your Money

Withdrawals    Contract Owners may withdraw some or all of the Accumulation Unit Value at any time before the Maturity Date. We may require that a Contract Value of at least $2,000 remain after a partial withdrawal. You may instruct us how to allocate your partial withdrawal request among your investments in the Divisions. If no direction is received, your withdrawal will be deducted proportionately from each of your investments.

Withdrawals may also be made after the Maturity Date. If Annuity Payments are being made under variable income plan 1, the payee may surrender the Contract and receive the value of the Annuity Units credited to his or her Contract. If Annuity Payments are being made under variable income plan 2 and the payee dies during the certain period (or if both payees die during the certain period of variable income plan 3), the beneficiary may surrender the Contract and receive the withdrawal value of the unpaid payments for the certain period. The withdrawal value is based on the Annuity Unit value on the withdrawal date, with the unpaid payments discounted at the Assumed Investment Rate. (See “Description of Variable Income Plans.”)

We may accept withdrawal or full surrender requests (including, but not limited to exchanges reported under IRC §1035 and direct trustee to trustee transfers) in writing or by telephone, subject to our administrative procedures, which may include the proper completion of certain forms, the provision of appropriate identifying information, and other administrative requirements. Full surrenders may require a signed form. Withdrawal requests may be submitted on properly completed Northwestern Mutual forms or an electronic order ticket. See “Owner Inquiries and Instructions” for more information. Improperly submitted and incomplete forms will not be considered to be in good order and will not be processed. We will process your request at the accumulation value next determined only after our receipt of your request in good order, which includes satisfaction of all our administrative requirements. Subject to our administrative procedures and our approval, you may request that a withdrawal be processed (or that an Income Plan start) on a future date you specify. Otherwise, we will pay the amount of any withdrawal from the Separate Account within seven days (or whatever period that may be required under applicable state law) after we receive the request in good order unless the suspension of payments or transfers provision is in effect. You may revoke a request for withdrawal on a specified future date any time prior to such future date. Subject to our rules, requirements, and availability, your Financial Representative may provide us with instructions on your behalf involving the frequency, amount, and destination of partial and complete withdrawals made under your Contract.

If mandated under applicable law, we may be required to block an Owner’s account and thereby refuse to pay any requests for transfer, partial withdrawal, surrender or death benefits, until instructions are received from the appropriate regulator. We may also be required to provide additional information about an Owner and an Owner’s account to government regulators.

Benefits Provided Under the Contracts

Subject to the restrictions noted below, we will pay the death benefit of a Contract in a lump sum or under the Income Plans described below. We reserve the right to defer determination of the withdrawal value of the Contracts, or the payment of benefits under a variable income plan, until after the end of any period during which the right to redeem shares of a Portfolio is suspended, or payment of the redemption value is postponed pursuant to the provisions of the 1940 Act because of one or more of the following: (a) the NYSE is closed, except for routine closings on holidays or weekends; (b) the SEC has determined that trading on the NYSE is restricted; (c) the SEC permits suspension or postponement and so orders; (d) an emergency exists, as defined by the SEC, so that valuation of the assets of the Funds or disposal of securities they hold is not reasonably practical; or (e) such suspension or postponement is otherwise permitted by the 1940 Act. If, under SEC rules, the Government Money Market Portfolio suspends payments of redemption proceeds in connection with a liquidation of the Portfolio, we will delay payment of any transfer, partial surrender, surrender or death benefit from the Government Money Market Division until the Portfolio is liquidated.

 

Death Benefit

How Much is the Death Benefit?    The amount of the Death Benefit depends in part on when the Annuitant dies. (Remember that the Annuitant is the person upon whose life the Contract is issued.)

 

•

If an Annuitant dies before the Contract’s Maturity Date—and on or after his or her 75th birthday, the Death Benefit will equal the Contract Value (determined as described below).

 

•

If an Annuitant dies after the Contract’s Maturity Date (which is stated on the specifications page of the Contract), or any time after Annuity Payments begin, no Death Benefit is payable. Income Plans have their own payout benefit rules at death. (See “Income Plans”.)

 

•

If an Annuitant dies before the Contract’s Maturity Date—and before his or her 75th birthday—the Death Benefit will equal the greater of the following:

•

the Contract Value (determined as described immediately below); or

 

•

the amount of Purchase Payments we received, less an adjustment for every withdrawal. (For each withdrawal, we reduce the minimum death benefit by the percentage of the Contract Value withdrawn.)

When is the Death Benefit Determined?    In determining the amount of the Death Benefit, the Contract Value is determined the date we receive proof of the Annuitant’s death at our Home Office. If we receive proof of death before the close of trading for the NYSE (typically, 4:00 p.m. Eastern Time), we will determine the Contract Value based on the value of the units in the Divisions determined at the close of that day’s trading session. If, however, we receive proof of death on or after the close of NYSE trading, we will determine the Contract Value based on the value of the units in the Divisions determined at the close of the next NYSE trading session.

 

How is the Death Benefit Distributed?    If the Owner is the Annuitant and dies before the Contract’s Maturity Date, the Beneficiary automatically becomes the new Owner and Annuitant, and the Contract continues in force. (If there is more than one Beneficiary for a given Contract, each Beneficiary must make his or her own method of payment election.) If the Contract continues in force, we will set the Contract Value at an amount equal to the Death Benefit. If this results in an addition to the Contract Value, we will place the additional amount in the Government Money Market Division and the Beneficiary (now, the new Owner) may transfer it to the Divisions chosen by such Beneficiary/Owner. Pursuant to the terms of the Contract, the Contract Value will remain invested in the same investment options as those at the time of the Annuitant’s death until such time as the Beneficiary elects to transfer to different investment options or to make a withdrawal.

If the Owner is not the Annuitant and the Annuitant dies before the Maturity Date, the contingent Annuitant automatically becomes the new Annuitant and the Contract continues in force. If no contingent Annuitant is named within 60 days (or whatever period that may be required under applicable state law) after we receive proof of death of the Annuitant, the Death Benefit becomes payable to the Owner.

If an Owner is the Annuitant and, during his or her life, elected an Income Plan (see “Income Plans”) for a Beneficiary, Annuity Payments begin to such Beneficiary upon the death of the Owner, as described above. If the Owner did not elect an Income Plan for a Beneficiary, the Beneficiary may elect to:

 

•

continue the Contract (as described above),

 

•

receive the Death Benefit under an Income Plan, subject to limitations under federal and/or state law, or

 

•

receive the Death Benefit as a lump sum check.

In any event, the Beneficiary must take distributions from the Contract pursuant to the applicable minimum distribution requirements. (See “Minimum Distribution Requirements.”) If no affirmative election is made, the Beneficiary will receive the Death Benefit as a lump sum check.

Income Plans

Generally    If you decide to begin receiving Annuity Payments from your Contract, you may choose either

(1) monthly payments for a specified period (guaranteed only for contracts issued before May 1, 2013), or (2) monthly payments for your life (assuming you are the Annuitant), and you may choose to have payments continue to your Beneficiary for the balance of 10 or 20 years if you die sooner, or (3) monthly payments for your life and for the life of another person (usually your spouse) selected by you. These Income Plans are available to you on a variable or fixed basis, or a combination thereof, depending on applicable state law. Your Contract may guarantee the right to other Income Plans, and we may offer other Income Plans from time to time from which you may choose when deciding to start receiving Annuity Payments. While no charges are assessed on fixed income plans, we will continue to assess mortality rate and expense risk charges on variable income plans. You will also continue to incur the fees and expenses of the underlying Portfolios in which you direct the assets supporting your Income Plan be invested. The fixed income plans are not described in this prospectus. If you select a fixed income plan, we will cancel any Accumulation Units credited to your Contract, transfer the withdrawal value of the Contract to our General Account, and you will no longer have any interest in the Separate Account.

A variable income plan means that the amount representing the actuarial liability under the variable income plan will continue to be invested in one or more of the investment choices you select. Your monthly Annuity Payments will vary up or down to reflect continuing investment performance. Under a variable income plan, you bear the entire investment risk, since we make no guarantees of investment return. Accordingly, there is no guarantee of the amount of the variable payments, and you must expect the amount of such payments to change from month to month. A fixed income plan, on the other hand, guarantees the amount you will receive each month. For a discussion of tax considerations and limitations regarding the election of Income Plans, see “Federal Income Taxes.”

On the Maturity Date, if you have not elected a permissible Income Plan (i.e., one offered by the Company for your Contract), we will change the Maturity Date to the Contract anniversary nearest the Annuitant’s 98^th birthday (if the Maturity Date is not already such date) and, upon that Maturity Date, we will pay the Contract Value in monthly payments for life under a variable income plan with payments certain for ten years, using your investment choices then in effect.

 

Description of Variable Income Plans    The following variable income plans are available:

1. Period Certain (sometimes referred to as Installment Income for a Specified Period).    An annuity payable monthly for a specified period of 10 to 30 years during the first five Contract years and over a specified period of 5 to 30 years beginning with the sixth Contract year (guaranteed only for contracts issued before May 1, 2013).

2. Single Life Income with or without Period Certain (sometimes referred to as Single Life Income with or without Certain Period).    An annuity payable monthly until the payee’s death, or until the expiration of a selected certain period, whichever is later. You may select a certain period of either 10 or 20 years, or you may choose a plan with no certain period. After the payee’s death, we will make any remaining guaranteed payments to the designated beneficiary.

3. Joint and Survivor Life Income with Period Certain (sometimes referred to as Joint and Survivor Life Income with Certain Period).    An annuity payable monthly for a certain period of 10 years and thereafter during the joint lifetime of two Joint Annuitants. On the death of either Joint Annuitant, payments continue for the remainder of the 10 years certain or the remaining lifetime of the survivor, whichever is longer.

We may, subject to applicable state law, limit the election of a variable income plan to one that results in an initial payment of at least $20. A variable income plan will continue even if payments fall to less than $20 after the plan begins. From time to time we may establish variable income plan rates with greater actuarial value than those stated in the Contract and make them available at the time of settlement. We may also make available other plans, with provisions and rates we publish for those plans.

After the effective date of an Income Plan which does not involve a life contingency (i.e., Plan 1), a payee may transfer to either form of life annuity (i.e., Plans 2 or 3) at no charge. We will apply the value of the remaining payments to the new plan selected. We will determine the amount of the first Annuity Payment under the new plan on the basis of the particular plan selected, the Annuity Payment rate, and the Annuitant’s adjusted age and sex. Subsequent payments will vary to reflect changes in the value of the Annuity Units credited. We may permit other transfers between Income Plans, subject to such limitations we may reasonably determine. Generally, however, we permit neither withdrawals from an Income Plan involving a life contingency nor transfer to an Income Plan that does not involve the same life contingency. Income plans for Beneficiaries may differ from those offered to Owners. At the written request of the Owner, we may impose restrictions on payments to beneficiaries.

Amount of Annuity Payments    We will determine the amount of the first Annuity Payment on the basis of the particular variable income plan you select, the Annuity Payment rate (i.e., the stream of projected annuity payments based on an actuarial projection of the length of time annuity payments will continue as well as other factors including the

assumed investment rate) and, for plans involving life contingencies, the Annuitant’s adjusted age and sex. (A contract with Annuity Payment rates that are not based on sex is also available.) We will calculate the amount of the first Annuity Payment on a basis that takes into account the length of time over which we expect Annuity Payments to continue. The first payment will be lower for an Annuitant who is younger when payments begin, and higher for an Annuitant who is older, if the variable income plan involves life contingencies. The first payment will be lower if the variable income plan includes a longer certain period. variable annuity payments after the first will vary from month to month to reflect the fluctuating value of the Annuity Units credited to your Contract. Annuity Units represent the actuarial value of a variable income plan’s interest in a Division of the Separate Account after Annuity Payments begin.

Assumed Investment Rate    The variable annuity rate tables for the Contracts are based upon an Assumed Investment Rate of 3¹⁄₂%. Variable Annuity rate tables based upon an Assumed Investment Rate of 5% are also available where permitted by state law. The Assumed Investment Rate affects both the amount of the first variable payment and the amount by which subsequent payments increase or decrease. The Assumed Investment Rate does not affect the actuarial value of the future payments as of the date when payments begin, though it does affect the actual amount which may be received by an individual Annuitant.

Over a period of time, if each Division achieved a net investment result exactly equal to the Assumed Investment Rate applicable to a particular variable income plan, the amount of Annuity Payments would be level. However, if the Division achieved a net investment result greater than the Assumed Investment Rate, the amount of Annuity Payments would increase. Similarly, if the Division achieved a net investment result smaller than the Assumed Investment Rate, the amount of Annuity Payments would decrease. A higher Assumed Investment Rate will result in a larger initial payment but more slowly rising and more rapidly falling subsequent payments than a lower Assumed Investment Rate.

 

We will make the following deductions:

Mortality Rate and Expense Risk Charges

Nature and Amount of the Charges    When we determine the value of Accumulation and Annuity Units, we deduct a charge for mortality rate and expense risks we have assumed. We assume, for example, the risk that Annuity Payments will continue for longer periods than anticipated because the Annuitants as a group live longer than expected. We also assume the risk that the charges we make may be insufficient to cover the actual costs we incur in connection with the Contracts, including other costs such as those related to marketing and distribution. We assume these risks for the duration of the Contract. In case these costs exceed the amount of the charges we collect, the costs will be paid out of our general assets. If the amount of the charge is more than sufficient to cover the mortality and expense risk, any excess may be used for any Company purpose.

The deduction from Accumulation Units and Annuity Units is at a current annual rate of 0.35% of the assets of the Separate Account. Our Board of Trustees may increase or decrease the deduction, but in no event may the deduction exceed an annual rate of 0.75%.

Other Expense Risks    The value of your Contract may reflect a deduction of any reasonable expenses which may result if there were a substitution of other securities for shares of the Portfolios as described under “The Separate Account” and any applicable taxes, (i.e., any tax liability) we have paid or reserved for resulting from the maintenance or operation of a Division of the Separate Account, other than applicable premium taxes which we may deduct directly from considerations. We do not presently anticipate that we will make any deduction for federal income taxes (see “Taxation of Northwestern Mutual”), nor do we anticipate that maintenance or operation of the Separate Account will give rise to any deduction for state or local taxes. However, we reserve the right to charge the appropriate Contracts with their shares of any tax liability which may result under present or future tax laws from the maintenance or operation of the Separate Account or to deduct any such tax liability in the computation of the value of such Contracts. Our right to make deductions for expenses resulting from a substitution of securities may be restricted by the 1940 Act.

Contract Fee    On each Contract anniversary prior to the Maturity Date, we make a deduction of $30 for administrative expenses relating to a Contract during the prior year. We make the charge by reducing the number of Accumulation Units credited to the Contract. We cannot increase this charge. The charge is intended only to reimburse us for our actual administrative expenses. We currently are waiving this charge.

Enhanced Death Benefit Charge    On each Contract anniversary on which the enhanced death benefit is in effect, we deduct from the Contract Value a charge based on the amount of the enhanced death benefit on the Contract Anniversary and the age of the Annuitant when the Contract was issued. The charge is 0.10% of the amount of the enhanced death benefit for issue age 45 or less, 0.20% for issue age 46-55, and 0.40% for issue age 56-65. This charge is for the risks we assume in guaranteeing the enhanced death benefit. We deduct the charge from the Divisions of the Separate Account in proportion to the amounts you have invested.

Premium Taxes    The Contract provides for the deduction of applicable premium taxes, if any, from Purchase Payments or from Contract benefits. Various jurisdictions levy premium taxes. Premium taxes generally range from 0% to 3.5% of total Purchase Payments. Many jurisdictions presently exempt from premium taxes annuities such as the Contract. As a matter of current practice, we do not deduct premium taxes from Purchase Payments received under the Contract or from Contract benefits. However, we reserve the right to deduct premium taxes in the future. The amount deducted, if any, may be more or less than the percentage charged by your state of residence.

Portfolio Expenses and Charges    The expenses borne by the Portfolios in which the assets of the Separate Account are invested are described in the attached mutual fund prospectuses.

For certain Portfolios, certain expenses may have been reimbursed or fees may have been waived during 2019 in addition to any contractual feel waiver or reimbursements. It is anticipated that any such voluntary expense reimbursement and fee waiver arrangements would continue past the current year, although certain arrangements may be terminated at any time. After taking into account these arrangements, as well as any contractual fee waiver or expense reimbursement arrangements, Annual Portfolio Operating Expenses would have ranged from a minimum of 0.20% to a maximum of 1.25%.

Expedited Delivery Charge    When, at your request, we incur the expense of providing expedited delivery of your redemption request (e.g., a complete or partial withdrawal) we assess the following charges: $15 for express mail delivery (plus $2 for “signature required” service) and $15 for a wire transfer.

 

Taxation of Contract Benefits

We offer the Contract for use in non tax-qualified situations (i.e., contributions are taxable). There are no limitations on who can purchase a non-tax qualified annuity or the amount that can be contributed to the Contract. Contributions to non-tax qualified Contracts are not deductible.

For Contracts held by individuals, no tax is payable as a result of any increase in the value of a Contract. Contract benefits will be taxable as ordinary income when received in accordance with Section 72 of the Internal Revenue Code of 1986, as amended (the “Code”). If the Owner of a non-tax qualified Contract elects to receive the entire value of the Contract as Annuity Payments under a variable income plan or fixed income plan, or a portion of the Contract as Annuity Payments under either Income Plan for a period of at least the Owner’s life expectancy or ten years, benefits received will be taxable as ordinary income to the extent they exceed that portion of each payment which represents the ratio of the Owner’s “investment in the contract” to the Owner’s “expected return” as defined in Section 72 of the Code (the “exclusion ratio”), until the entire “investment in the contract” is recovered. Benefits received in a lump sum or as partial annuity payments that do not qualify for exclusion ratio taxation will be taxable as ordinary income to the extent they exceed the “investment in the contract.” A partial withdrawal or collateral assignment prior to the Maturity Date will result in the receipt of gross income by the Owner to the extent that the amounts withdrawn or assigned do not exceed the excess (if any) of the total value of Accumulation Units over total purchase payments paid under the Contract less any amounts previously withdrawn or assigned. Thus, any investment gains reflected in the Contract Values are considered to be withdrawn first and are taxable as ordinary income. Investment gains will be determined by aggregating all non-tax qualified deferred Contracts we issue to the Owner during the same calendar year.

A penalty tax of 10% of the amount of the payment which is includible in income will be imposed, by federal tax law, on non-exempt withdrawals of Contract benefits. Payments which are exempt from the penalty tax include payments upon disability, after age 59¹⁄₂ and for certain substantially equal periodic payments.

For taxable years beginning in 2013, part or all of the taxable benefits from and sales of non-tax qualified Contracts may be subject to an additional 3.8% Medicare tax. The tax will be assessed on the Owner’s net investment income for the year to the extent that the Owner’s adjusted gross income (with slight modifications) exceeds $250,000 (married filing jointly or surviving spouse), $125,000 (married filing separately) or $200,000 (other filers) (not indexed). The term “net investment income” is defined to include payments from non-tax qualified annuities and dispositions of property. You should consult a tax advisor about the impact of this new tax on distributions from your contract/policy.

One or more non-tax qualified Contracts can be wholly or partially exchanged for one or more other annuity contracts under Section 1035 of the Code without recognition of gain or loss. However, withdrawals taken within 6 months after a partial exchange may cause the partial exchange to be taxed as a withdrawal. Certain nonqualified Contracts not held by individuals, such as Contracts purchased by corporate employers in connection with deferred compensation plans, will not be taxed as annuity Contracts and increases in the value of the Contracts will be taxable in the year earned.

The Owner of a non-tax qualified Contract is not required to take required minimum distributions during the Owner’s lifetime. However, the Contract death proceeds must be distributed to any non-spouse beneficiary either within five years of the Owner’s death or as substantially periodic payments over the beneficiary’s life or life expectancy commencing within one year of the Owner’s death. The surviving spouse, as defined under federal tax law, is not subject to any distribution requirements.

Taxation of Northwestern Mutual

We may charge the appropriate Contracts with their shares of any tax liability which may result from the maintenance or operation of the Divisions of the Separate Account. We are currently making no charge. (See “Deductions.”)

Other Considerations

You should understand that the tax rules for annuities are complex and cannot be readily summarized. The foregoing discussion does not address special rules applicable in many situations, rules governing Contracts issued or purchase payments made in past years, current legislative proposals, or state or other law. This tax discussion is intended for the promotion of Northwestern Mutual Life products. It does not constitute legal or tax advice, and is not intended to be used and cannot be used to avoid any penalties that may be imposed on a taxpayer. Taxpayers should seek advice based on their particular circumstances from an independent tax advisor. Before you purchase a Contract, we advise you to consult qualified tax counsel.

 

Automatic Dollar-Cost Averaging    The Dollar-Cost Averaging Plan is an investment strategy designed to reduce the investment risks associated with market fluctuations. The strategy spreads the allocation of money (expressed in whole percentages and in amounts of at least $100) into the Divisions over a period of time by systematically and automatically transferring, on a monthly, quarterly, semi-annual, or annual basis, specified dollar amounts from the Government Money Market Division into the other Division(s). This allows you to potentially reduce the risk of investing most of your Purchase Payments into the Divisions at a time when prices are high. Transfers will end either when the amount in the Government Money Market Division is depleted or when you notify us to stop such transfers, whichever is earlier. There is no charge for the Dollar-Cost Averaging Plan. We reserve the right to modify or terminate the Dollar-Cost Averaging Plan at any time.

Dollar cost averaging does not assure a profit or protect against loss in a declining market. Carefully consider your willingness to continue payments during periods of low prices. You should consult your Financial Representative before deciding whether to elect dollar cost averaging.

Electronic Funds Transfer (“EFT”)    Another convenient way to invest using the dollar-cost averaging approach is through our EFT Plan. These automatic withdrawals allow you to add Purchase Payments to the Division(s) within your Contract on a regular monthly basis through payments drawn directly on your checking account. There is no charge for the EFT service.

A program of regular investing cannot assure a profit or protect against loss in a declining market.

Systematic Withdrawal Plan    You can arrange to have regular amounts of money sent to you while your Contract is still in the accumulation phase. Our Systematic Withdrawal Plan allows you to automatically redeem Accumulation Units to generate monthly payments. The withdrawals may be taken either proportionately from each Portfolio or from specific Portfolios you designate. Systematic withdrawals continue until at least one of the following occurs: (1) the amount in any of the selected Portfolios is depleted; (2) less than 100 Accumulation Units remain in the Contract; (3) a systematic withdrawal plan terminates; or (4) when the final amount is distributed and there is no value left in the Contract (in which case the Contract will terminate); or (5) you terminate systematic withdrawals. You may have to pay income taxes and tax penalties on amounts you receive. There is no charge for the Systematic Withdrawal Plan service. We reserve the right to modify or terminate this Systematic Withdrawal Plan at any time.

Portfolio Rebalancing    To help you maintain your asset allocation over time, we offer a rebalancing service. This will automatically readjust your current investment option

allocations, on a periodic basis (i.e., monthly, quarterly, semi-annually, or annually), back to the allocation percentages you have selected. There is no charge for this Portfolio Rebalancing feature. We reserve the right to modify or terminate this Portfolio Rebalancing feature at any time. If you transfer between underlying investment options, automatic portfolio rebalancing (“APR”) will ordinarily end and you will need to make a new APR election if you want APR to continue.

Only Contracts with accumulation values of $10,000 or more or those Contracts that have been annuitized are eligible. A program of regular investing cannot assure a profit or protect against loss in a declining market.

Substitution of Portfolio Shares and Other Changes    When permitted by law and subject to any required regulatory approvals, we reserve the right to eliminate a Portfolio and to substitute another Portfolio or mutual fund for such Portfolio (or substitute a class of shares of an existing Portfolio for a different class of the same Portfolio) if the shares of the Portfolio are no longer available for investment or, in our judgment, further investment in the shares of the Portfolio is no longer appropriate. In the event we take any action to substitute another Portfolio in the future, we may make an appropriate endorsement of your Contract and take other necessary actions.

Owner Inquiries and Instructions    Get up-to-date information about your Contract at your convenience with your User ID and password. Visit our website (www.northwesternmutual.com) to enroll for access to Division performance information, forms for routine service, and daily unit values for Contracts you own with your User ID and password. Eligible Owners may also set up certain electronic payments, transfer invested assets among investment Divisions, and change the allocation of future contributions online, subject to our administrative procedures. For questions about your Contract or Division values, assistance with payments or distributions, or other contract changes (such as transferring among investment options, changing allocations, or obtaining Division performance information), please contact us toll-free at 1-888-455-2232.

The submission of transfer or withdrawal instructions by telephone or through our website (“Electronic Instructions”) must be made in accordance with our then current procedures for Electronic Instructions. However, we are not required to accept Electronic Instructions, and we will not be responsible for losses resulting from transactions based on unauthorized Electronic Instructions, provided we follow procedures reasonably designed to verify the authenticity of Electronic Instructions. Please note that the telephone and/or electronic devices may not always be available. Any telephone or electronic device, whether it is yours, your service provider’s, or your agent’s or ours, can experience outages or slowdowns for a variety of reasons, which may delay or prevent our

 

processing of your request. Although we have taken precautions to limit these problems, we cannot promise complete reliability under all circumstances. If you are experiencing problems, you should make your transfer request by writing to our Home Office. We reserve the right to limit, modify, suspend, or terminate the ability to make transfers via Electronic Instructions.

Householding    To reduce costs, we now send only a single copy of the same disclosure document(s) (such as

prospectuses, prospectus supplements, reports, announcements, proxy statements, notices, and information statements) to each consenting household (rather than sending copies to each Owner residing in a household). If you are a member of such a household, you can revoke your consent to “householding” at any time, and can begin receiving your own copy of such disclosure documents by calling us at 1-888-455-2232.

 

The Distributor    We sell the Contracts through our Financial Representatives who also are registered representatives of Northwestern Mutual Investment Services, LLC (“NMIS”). NMIS, our wholly-owned company, was organized under Wisconsin law in 1998 and is located at 720 East Wisconsin Avenue, Milwaukee, Wisconsin 53202. NMIS is a registered broker-dealer under the Securities Exchange Act of 1934 and is a member of the Financial Industry Regulatory Authority. NMIS is the principal underwriter of the Contracts, and has entered into a Distribution Agreement with us. No sales charges are paid on sales of the Contracts, and no underwriting commissions have been paid, or retained, by NMIS.

Northwestern Mutual variable insurance and annuity products are available exclusively through NMIS and its registered representatives and cannot be held with or transferred to an unaffiliated broker-dealer. Except in limited circumstances, NMIS registered representatives are required to offer Northwestern Mutual variable insurance and annuity products. The amount and timing of sales compensation paid by insurance companies varies. The commissions, benefits, and other sales compensation that NMIS and its registered representatives receive for the sale of a Northwestern Mutual variable insurance or annuity product might be more or less than that received for the sale of a comparable product from another company.

NMIS and the Northwestern Mutual Wealth Management Company (“NMWMC”) use a system referred to as a “grid” for paying registered representatives commissions and fees for the sale or servicing of other investments such as mutual funds in brokerage accounts or advisory accounts. The higher level of overall commissions or fees for investments that your registered representative is responsible for generating, the higher percentage of commissions or fees they receive, which in turn lowers the percentage of fees or commissions retained by NMIS or NMWMC; those breakpoints and percentages are what is referred to as the grid. The grid payout percentages range between 35% and 95% payable to the registered representative, depending on the level of sales or fees generated by that registered representative during the previous year. Therefore, a registered representative’s current year grid level is set based on the registered representative’s previous year’s sales production. Sales of Contracts count towards sales

production used to measure grid placement, even though commissions for Contracts are not paid out through the grid. The ability to improve grid placement in the following year provides an incentive for your registered representative to sell the Contract.

Because registered representatives of the Distributor are also our appointed agents, they may be eligible for various cash benefits, such as additional bonuses, insurance benefits, retirement benefits, and non-cash compensation programs that we offer, such as conferences, achievement recognition, prizes, and awards. In addition, Distributor’s registered representatives who meet certain productivity, persistency and length of service standards and/or their managers may be eligible for additional compensation. For example, registered representatives who meet certain annual sales production requirements with respect to their sales of Northwestern Mutual insurance and annuity products may qualify to receive additional cash compensation for their other sales of investment products and services. Sales of the Contracts may help registered representatives and/or their managers qualify for such compensation and benefits.

Certain of the Distributor’s registered representatives may receive other payments from us for the recruitment, development, training, and supervision of Financial Representatives, production of promotional literature, and similar services. Commissions and other incentives and payments described above are not charged directly to Owners or to the Separate Account. We intend to recoup sales expenses through fees and charges deducted under the Contract.

Dividends    This Contract is eligible to share in the divisible surplus, if any, of the Company, except while payments are being made under a variable income plan. Each year we determine, in our sole discretion, the amount and appropriate allocation of divisible surplus. Divisible surplus credited to your Contract is referred to as a “dividend.” There is no guaranteed method or formula for the determination or allocation of divisible surplus. The Company’s approach is subject to change. There is no guarantee of a divisible surplus. Even if there is a divisible surplus, the payment of a dividend on this Contract is not guaranteed. It is not expected that any dividends will be payable on this Contract, except, possibly, on certain fixed installment plans.

 

We will credit dividends, if any, attributable to your Contract on the Contract anniversary. Dividends, if any, credited prior to the Maturity Date will be applied as a Net Purchase Payment on the Contract anniversary unless the Owner elects to have the dividend paid in cash. However, if the NYSE is closed on the Contract Anniversary, the amount of any dividend will be applied as of the next Valuation Date after the Contract anniversary. Dividends, if any, applied as a Net Purchase Payment will be allocated to the Divisions of the Separate Account according to the allocation of Net Premiums then in effect.

Voting Rights    As long as the Separate Account continues to be registered as a unit investment trust under the 1940 Act, and as long as Separate Account assets of a particular Division are invested in shares of a given Portfolio, we will vote the shares of that Portfolio held in the Separate Account in accordance with instructions we receive from (i) the Owners of Accumulation Units supported by assets of that Division; and (ii) the payees receiving payments under variable income plans supported by assets of that Division. Periodic reports relating to the Portfolios, proxy material, and a form (on which one can give instructions with respect to the proportion of shares of the Portfolio held in the Account corresponding to the Accumulation Units credited to the Contract, or the number of shares of the Portfolio held in the Account representing the actuarial liability under the Variable Income Plan, as the case may be) will be made available to each Owner or payee. The number of shares will increase from year to year as additional purchase payments are made by the Contract Owner; after a variable income plan is in effect, the number of shares will decrease from year to year as the remaining actuarial liability declines. We will vote shares for which no instructions have been received in the same proportion as the shares for which instructions have been received from Contract Owners and payees. Because of this proportional voting requirement, it is possible that a small number of Contract Owners and payees could determine the outcome of a particular vote.

Internal Annuity Exchanges    As a matter of current practice, which we may limit or stop at any time in our discretion, we permit owners of certain fixed and variable annuity contracts that we have previously issued to exchange those contracts for the Contract. Such exchanges are not intended to be available for all owners, as they may not be in a particular owner’s best interest. We are not presently charging an administrative fee on these transactions. We permit only one such transaction in any 12-month period.

Amounts exchanged from a front-load Contract to a Contract will not be subject to any additional front-end sales charge or withdrawal charge. We currently do not allow an exchange from a variable annuity contract we previously issued to a Contract when amounts exchanged from the previously issued variable annuity contract would be subject to a withdrawal charge, although we may allow such exchanges when there are no applicable withdrawal charges on the Contract being exchanged. Fixed annuity contracts, which are not described in this prospectus, are available for exchange to a Contract,

however, any applicable withdrawal charge or market value adjustment may be assessed on amounts exchanged from the fixed annuity contract.

It is our current practice not to allow exchanges from a Contract to a back-load variable annuity contract, front-load variable annuity contract, or fixed annuity contract.

Speculative Investing    Do not purchase this contract if you plan to use it, or any of its riders, for any type of speculative collective investment scheme (including, for example, arbitrage). Your Contract is not intended to be traded on any stock exchange or secondary market, and attempts to engage in such trading may violate state and/or federal law.

Abandoned Property Requirements    Every state has unclaimed property laws which generally declare insurance contracts/policies to be abandoned after a period of inactivity of three to five years from the contract’s/policy’s maturity date, the date the death benefit is due and payable, or in some states, the date the insurer learns of the death of the insured. For example, if the payment of the death benefit has been triggered, but, if after a thorough search, we are still unable to locate the beneficiary, or if the beneficiary does not come forward to claim the death benefit proceeds in a timely manner, the death benefit proceeds will be paid to the abandoned property division or unclaimed property office of the state in which the beneficiary or you last resided, as shown on our books and records, or to our state of domicile. This “escheatment” is revocable, however, and the state is obligated to pay the death benefit proceeds (without interest) if your beneficiary steps forward to claim it with the proper documentation. To prevent such escheatment, it is important that you update your beneficiary designations, including addresses, if and as they change. Please call 1-888-455-2232 to make such changes.

Cybersecurity & Certain Business Continuity Risks     The Company has administrative, technical and administrative safeguards in place with respect to information security, nevertheless, our variable product business is potentially susceptible to operational and information security risks resulting from a cyber-attack as it is highly dependent upon the effective operation of our computer systems and those of our business partners. These risks include, among other things, the theft, misuse, corruption and destruction of data maintained online or digitally, denial of service on websites and other operational disruption and unauthorized release of confidential customer information. Cyber-attacks affecting us, the underlying funds, intermediaries and other affiliated or third-party service providers may adversely affect us and your Contract Value. For instance, cyber-attacks may interfere with our processing of contract transactions, including the processing of orders from our website or with the underlying funds, impact our ability to calculate AUVs, cause the release and possible destruction of confidential customer or business information, impede order processing, subject us and/or our service providers and intermediaries to regulatory fines and financial losses and/or cause reputational damage. Cybersecurity risks may also impact the issuers of securities in which the underlying funds invest, which may cause the funds

 

underlying your Contract to lose value. There can be no assurance that we or the underlying funds or our service providers will avoid losses affecting your Contract due to cyber-attacks or information security breaches in the future.

Other disruptive events, including (but not limited to) natural or man-made disasters and public health crises or pandemics (such as coronavirus COVID-19), may also adversely affect our ability to conduct business, including if our employees or the employees of intermediaries or other affiliated or third-party service providers are unable to perform their responsibilities as a result of any such event. Such disruptions to our business operations can interfere with issuance or our processing of transactions (including the processing of orders through our website or with the Portfolios), may interfere with our ability to receive, pickup and process mail and messages, impact our ability to calculate values, or cause other operational or system issues. Furthermore, these disruptions

may persist even if our employees or the employees of intermediaries or other affiliate or third-party service providers are able to work remotely. These events may also impact the issuers of securities in which the Portfolios invest, which may cause the Portfolios to lose value. There can be no assurance that the Company, the Portfolios or our service providers will avoid losses affecting your Contract due to a disaster or other catastrophe.

Legal Proceedings    Northwestern Mutual, like other life insurance companies, generally is involved in litigation at any given time. Although the outcome of any litigation cannot be predicted with certainty, we believe that, as of the date of this prospectus, there are no pending or threatened lawsuits that will have a materially adverse impact on the ability of Northwestern Mutual to meet its obligations under the Contract, on the Separate Account, or on NMIS and its ability to perform its duties as underwriter for the Separate Account.
