You may invest in up to 30 Divisions at a time. Under certain circumstances Northwestern Mutual reserves the right to remove a Portfolio or substitute another Portfolio or mutual fund for such Portfolio .

Overview of the Policy

What is the Policy, and what is it designed to do?

The Policy is an individual flexible premium variable universal life insurance policy, the purpose of which is primarily to provide life insurance protection (i.e., a death benefit) while providing the long-term growth in the Policy Value through allocations to a variety of Divisions and/or a fixed account option. The Policy may be appropriate if you have a long-term investment horizon and is not intended for short-term investment, and is therefore not appropriate for people who may need to make early or frequent withdrawals or who intend to engage in frequent trading. You may want to consult your financial or tax advisor.

In exchange for your Premium Payments, upon the death of the Insured, we will pay the Death Benefit to your beneficiary based on one of three death benefit options available under the Policy. Subject to certain limitations, you can change the Death Benefit option you selected. (See “ Death Benefit – Changing Death Benefit Options” in the Prospectus for more information.)

How are Premium Payments treated under the Policy?

As described in more detail in the “Information About the Policy” section of the Prospectus, when you apply for the Policy you must make a minimum initial Premium Payment to put your Policy in force. No insurance will take effect until the minimum initial Premium Payment is made. The minimum initial Premium Payment is based on the Issue Age, underwriting classification and sex of the Insured, the Initial Specified Amount, any optional benefits and, if applicable, the Death Benefit Guarantee Period. For certain Death Benefit Guarantee Periods, a minimum Premium Payment is required to be paid in the first Policy Year .

After the Policy is issued, you must make sufficient Premium Payments to keep the Policy in force. There is no required schedule or amount of Premium Payments but the investment results of the Divisions and the SAS Account to which your Net Premium(s) is allocated will affect the Premium Payments you are required to make to keep your Policy in force. If you elect the Death Benefit Guarantee, your Policy will generally not lapse regardless of the investment performance of the Divisions in which you invest so long as you make the minimum requested payment upon notice that your cumulative premium payments are below the required amount.

When a Premium Payment is received in Good Order at our Home Office after the Policy is in-force, we deduct a premium tax charge, federal deferred acquisition cost charge and sales load to cover taxes and acquisition and distribution expenses, respectively, and the remaining amount, known as the Net Premium(s), is allocated among the Divisions and the SAS Account, according to your current payment allocation instructions. Depending on the state in which we issue the Policy, we may hold your initial Net Premium in the Government Money Market Division until the later of the day after your right to return the Policy expires and the day we receive notice of delivery of your Policy.

Variable Universal Life Plus Prospectus

Investments in the Policy’s Divisions are held in the Separate Account which is an account separate from our General Account assets. We have established a segment within the Separate Account to receive and invest Net Premium(s) for the Policy. Currently, the Policy segment is divided into 59 Separate Account Divisions. Each Division purchases shares in a corresponding Portfolio. Information about each corresponding Portfolio is provided at the back of this document. See APPENDIX A: Portfolios Available under Your Policy.

Net Premium applied and amounts transferred to the SAS Account accrue interest daily at an effective annual rate Northwestern Mutual determines without regard to the investment experience of the General Account. The SAS Account is the sum of two separate balances, a Tier One balance and a Tier Two balance. The Tier One balance credits an annual guaranteed effective interest rate at least as high as the rate of the Tier Two balance. Northwestern Mutual guarantees a minimum annual effective interest rate of 1.50% for the Tier One balance and 1.25% for the Tier Two balance. (See “The Fixed Option (NM Strength and Stability Account)” in the Prospectus.)

Payment of insufficient premiums may result in the Policy terminating or lapsing, subject to the Death Benefit Guarantee explained below (if applicable).

Q. What are the primary features and options that the Variable Universal Life Plus Policy offers?

Choice of Death Benefit Options. You may choose among three Death Benefit options, a death benefit based on the Specified Amount (Option A), on the Specified Amount plus Policy Value (Option B) or on the Specified Amount plus cumulative premiums paid (less any cumulative withdrawals)(Option C). In addition to the three Death Benefit options, there is also a Minimum Death Benefit that may be applied. See the “Death Benefit” section in the Prospectus for more information.

Surrenders and Withdrawals. You may surrender your Policy, and we will pay you its Cash Surrender Value (Policy Value less any Policy Debt and any surrender charge). You may also withdraw a part of the Policy Value. A withdrawal reduces the Policy Value, may reduce the Specified Amount of the Policy and therefore the Death Benefit, may impact the Death Benefit Guarantee, and may increase the risk that the Policy will terminate or lapse. Surrenders and withdrawals are subject to charges and may have adverse tax consequences.

Loans. You may take a loan on the Policy that when added to existing Policy Debt does not exceed the Loan Value of the Policy. The Policy secures the loan. Taking a loan will reduce Cash Surrender Value and the Death Benefit, may impact the Death Benefit Guarantee, may have adverse tax consequences and will increase the risk that your Policy may terminate or lapse.

Transfers. Generally, you may transfer Contract Fund Value among up to 30 Divisions and the SAS Account, subject to certain restrictions on transfers to the Government Money Market Division and the SAS Account. We also offer four asset allocation models and two automated transfer programs: dollar cost averaging and portfolio rebalancing.

Death Benefit Guarantee. During a defined period elected at issue, your Policy will not terminate or lapse, even if the Cash Surrender Value is not enough to pay Monthly Policy Charges, as long as you have made specified minimum Premium Payments. However, even if specified minimum Premium Payments have been made, Policy loans and withdrawals could cause the Policy to terminate.

Collateral Assignment. Subject to our approval, you may generally assign the Policy as collateral for a loan or other obligation.

Tax Treatment. You are generally not taxed on the Policy’s earnings until you surrender or withdraw Policy Value from your Policy. This is known as tax deferral.

Additional Benefits. There are additional benefits you may add to your Policy . An additional charge may apply if you elect an additional benefit. The additional benefits available with this Policy are listed in the “Other Benefits Available under the Policy ” section of the Prospectus , and include the following:

●

Waiver Benefit: Selected Monthly Premium – Credits the Policy the Selected Monthly Premium Benefit if the Insured has a Total Disability

●

Additional Purchase Benefit – Allows the Owner to purchase additional life insurance policies on the life of the Insured without proof of insurability

●

Death Benefit Guarantee – Allows you to select a Death Benefit Guarantee Period during which the Policy is guaranteed not to terminate due to insufficient value in your Policy

●

Death Benefit Guarantee Premium Suspension – Allows for the suspension of required premiums during the Death Benefit Guarantee Period until your next Policy Anniversary

●

Income Plans – In lieu of a lump sum payment, the Death Benefit and surrender proceeds may be payable in monthly (or less frequent) payments over a period of time

●

Exchange for a Fixed Benefit Policy – Allows you to exchange your Policy for a life insurance policy with benefits that do not vary with the investment experience of the underlying Portfolios

Variable Universal Life Plus Prospectus

●

Paid-up Insurance – Under certain conditions allows the Owner to change the Policy to a policy free of minimum premium payment obligations

●

Dollar Cost Averaging – On a monthly basis, automatically transfers a specific amount from the Government Money Market Division into the other Divisions you have selected

●

Portfolio Rebalancing – Automatically rebalances the Divisions you select (either monthly, quarterly, semi-annually or annually) to maintain your chosen allocations among the Divisions

●

Allocation Models – Models are available that comprise a combination of Divisions representing various asset classes with various levels of risk tolerance

●

Terminal Illness Benefit – If the insured is diagnosed with a terminal illness, the owner can accelerate the death benefit and will receive the requested death benefit less interest, administrative fees, loan adjustment, and any required minimum premium. This benefit will become available under the Policy on or about July 1, 2025.

Standard Death Benefits

The Policy offers three Death Benefit options based on your “ Specified Amount,” which is an amount you select, subject to minimums (currently $100,000 for most ages) and underwriting requirements and the “Minimum Death Benefit,” which is the amount required by federal tax law to maintain the Policy as a life insurance contract. The three standard Death Benefits the Owner must choose on the Application are:

●

Option A—the greater of the Specified Amount or the Minimum Death Benefit;

●

Option B—the greater of the Specified Amount plus Policy Value or the Minimum Death Benefit; or

●

Option C—the greater of the Specified Amount plus cumulative premiums minus cumulative withdrawals or the Minimum Death Benefit.

No matter which Death Benefit you choose, insurance coverage becomes effective on the date we issue the Policy (generally the date on which we accept your Application, determine you meet our underwriting and administrative requirements and receive any required initial premium). The Death Benefit is usually payable within seven days after we receive satisfactory proof of the Insured’s death and is calculated as of the date of the Insured’s death. Amounts payable will include deductions for any Policy Debt, withdrawals made after the Insured’s death or adjustments required if the Insured dies during the Policy Grace Period. We increase the Death Benefit, if necessary, in order for the Policy to meet Minimum Death Benefit requirements.

You may decrease the Specified Amount while the Policy is in force, generally upon written request and subject to our approval. We will not permit a decrease if such decrease results in a Specified Amount less than the minimum Specified Amount we would require for issuance of a new Policy at the time of the change. You may not increase the Specified Amount after initial purchase. We reserve the right to charge for more than one change to the Specified Amount in a Policy Year. We will deduct any such charge from the Contract Fund Value.

Amounts paid under the Death Benefit are payable in a lump sum or under one of the fixed Income Plan options chosen by the Owner . If an Income Plan was not previously elected by the Owner (while the Insured was living or within 60 days after the death of the Insured if the Insured was not the Owner) and in lieu of a lump sum or other payment agreed to by Northwestern Mutual, the beneficiary (or contingent beneficiary) may elect to receive his or her share by a fixed Income Plan offered by the Policy.

The Policy also offers an optional Death Benefit Guarantee under which you select a Death Benefit Guarantee Period during which the Policy is guaranteed not to terminate provided certain conditions are met during a specified period. After a Policy is issued, you may change the Policy’s Death Benefit option or change the Specified Amount, generally upon written request, subject to our approval.

Other Benefits Available Under the Policy

In addition to the standard death benefits associated with your Policy, other standard and/or optional benefits may also be available to you. The following table(s) summarize information about those benefits. If applicable, information about the fees associated with each benefit included in the table may be found in the Fee and Expense Tables.

Buying the Policy

When you apply for a Policy, you must instruct us in the Application or supplement to the Application to allocate your Net Premium to one or more of the investment options including the SAS Account. Net Premiums are Premium Payments less deductions, such as premium expense charges. Premium Payments provided prior to the In Force Date will be placed in our General Account. On the In Force Date initial Net Premium is allocated to either the Government Money Market investment Division (if prior to the Initial Allocation Date) or your selected investment options, including the SAS Account. Your Initial Allocation Date is based on the date we approve your Policy, any later Policy Date you choose, as well as your state of issue and its right to return laws. Your initial allocation instructions remain in effect for subsequent Premium Payments until we receive your request to change them.

A minimum initial Premium Payment (based on age, underwriting classification, your Specified Amount, any optional benefits and, if applicable, the Death Benefit Guarantee Period) is required to put the Policy in force. For certain Death Benefit Guarantee Periods , a minimum Premium Payment is required to be paid in the first Policy Year . Although you must make sufficient Premium Payments to keep the Policy in force, after issue there is no required schedule or amount of Premium Payments required. However, if you elect a Death Benefit Guarantee, a minimum Premium Payment is required to meet the test required to maintain the guarantee. In addition to restrictions on transfers among investment options (including the SAS Account), there are also limits on allocations into the Government Money Market Division and/or the SAS Account (which vary depending on whether you have a Death Benefit Guarantee as noted in the Prospectus) as follows:

●

Amounts may not be allocated or transferred into the SAS Account and/or the Government Money Market Division if such allocation or transfer would cause the sum of the amounts in these options to exceed the limits described in the Policy

●

No Net Premiums may be allocated, or amounts transferred, to the SAS Account and/or the Government Money Market Division if such allocation or transfer would cause the percent of Net Premiums that may be allocated and/or transferred, as applicable, to these options to exceed the limits described in the Policy

●

No amounts may be allocated to the SAS Account if the current declared annual effective interest rate for the tier two portion of the SAS account is not greater than the minimum guaranteed annual effective interest rate

You may not make any Premium Payments after the Policy Anniversary nearest the Insured’s 121st birthday and additional Premium Payments may not be less than $25. A Premium Payment that would either exceed cumulative premiums illustrated in the Application or increase the Policy’s Death Benefit more than it increases the Policy Value will be accepted only if: the insurance in force, as increased, will be within issue limits; our insurability requirements are met; and the Premium Payment is received prior to the Policy Anniversary nearest the Insured’s 85th birthday. We also may limit the processing of Premium Payments as necessary for the Policy to qualify as life insurance under federal tax law, to avoid classification as a modified endowment policy, or if mandated under applicable law. In addition, minimum payments may be required during the Policy Grace Period to avoid lapse (see “How Your Policy Can Lapse” below).

The Policy has a Minimum Death Benefit, which is the amount required by federal tax law to maintain the Policy as a life insurance contract. A Policy must satisfy a testing method (irrevocably chosen at time of issue) that requires the Death Benefit to equal or exceed a defined relationship, or multiple of, the Policy’s value. Such a test may limit the amount of Premium Payment that may be paid in each Policy Year .

How Your Policy Can Lapse

Unless the Death Benefit Guarantee is in effect, if the value of your Policy is less than Monthly Policy Charges as of a Monthly Processing Date, your Policy will enter a 61 day Policy Grace Period . At the end of the Policy Grace Period your Policy will terminate (i.e., lapse) with no value and your insurance coverage will end, unless you submit a payment to keep the Policy in force. We will send you a notice indicating the minimum payment amount required to keep the Policy in force and the date by which you must make the payment. The payment must equal an amount that will cover all Monthly Policy Charges that were due and unpaid before the end of the Policy Grace Period and cover Monthly Policy Charges for three months. If the Insured dies during the Policy Grace Period we will deduct any Monthly Policy Charges due and unpaid from the Death Benefit.

If your Policy lapses you may reinstate it within three years (or longer if required under state law) following the termination date, subject to our approval, satisfaction of our current underwriting requirements and provided you make at least the minimum payment (see above). To reinstate the Policy, you must make a Premium Payment equal to an amount that will cover all Monthly Policy Charges that were due and unpaid before the end of the Policy Grace Period and cover Monthly Policy Charges for three months. Any Policy Debt that was outstanding when the Policy terminated will also be reinstated. On the

Variable Universal Life Plus Prospectus

effective date of the reinstatement, your Policy Value will be equal to the sum of Net Premium paid upon reinstatement and any Policy Debt on the termination date minus the total of Monthly Policy Charges due and unpaid prior to the end of the Policy Grace Period and the Monthly Policy Charges due on the date of reinstatement. Net Premium paid upon reinstatement will not include any interest from the date of the lapse. Upon reinstatement, your Policy Date will not change and your Death Benefit will remain the same as of the date of lapse and fees and charges that vary by Policy Year will take into account the period of time your Policy was terminated. If a surrender charge was assessed at the time of lapse, the Policy Value when a Policy is reinstated will include a credit for such surrender charge.

Making Withdrawals: Accessing Money in Your Policy

You may surrender your Policy for the Cash Surrender Value (the Policy value minus debt) at any time while the Insured is alive and the Policy is in force. We determine the Cash Surrender Value on the date your request for surrender (received in Good Order) is effective, which is any day the NYSE is open (generally if received before 4:00 p.m. Eastern Time) or on the next day the NYSE is open if received after. We may require you to return your Policy to our Home Office when you request a surrender of the Policy. We will pay surrender proceeds in a lump sum or under an Income Plan option you select. We will generally pay surrender proceeds within seven days of the effective date of the request.

Upon written request while the Insured is alive and the Policy is in force, you may also make a withdrawal, subject to Northwestern Mutual’s right to assess a charge in an amount up to $25 per withdrawal (currently waived). You may make no more than four withdrawals in a Policy Year. Each withdrawal must be at least $250, and you may not withdraw an amount that would:

●

reduce the Loan Value, net of any applicable service charge, to less than the Policy Debt (the Loan Value is an amount equal to 90% of the excess of your Policy Value over any applicable surrender charge less Policy Debt);

●

for a Policy with Death Benefit Option A, withdraw an amount which would reduce the Specified Amount to less than the minimum Specified Amount required for issuance of a Policy at the time of withdrawal (unless this Policy is in force under Paid-up insurance); or

●

reduce the Cash Surrender Value to less than the sum of three times the most recent Monthly Policy Charge.

A withdrawal may also decrease the Specified Amount used to determine the Death Benefit for certain Death Benefit options.

Written requests for withdrawal will be processed and effective on the date we receive the request in Good Order at our Home Office. Requests received any day the NYSE is open, if received before 4:00 p.m. Eastern Time, are deemed received and effective that day. If the request is received after 4:00 p.m. Eastern Time, the request will be deemed to be received and effective on the next day the NYSE is open. We will generally pay withdrawal proceeds within seven days of the effective date of the request.

Fee and Expense Tables

Wire Transfer Fee6,8	When a wire transfer is requested	$50 per transfer (up to $100 for international wires) adjusted for inflation9	$25 per transfer (up to $50 for international wires)

This charge was previously referred to as the “OBRA Expense Charge” or “Other Premium Expense Charge.” Due to a federal tax law change under the Omnibus Budget Reconciliation Act of 1990, as amended (“OBRA”), insurance companies are generally required to capitalize and amortize certain acquisition expenses rather than currently deduct such expenses. Due to this capitalization and amortization, the corporate income tax burden on insurance companies has been affected. This charge compensates us for the additional corporate income tax burden resulting from OBRA.

The Target Premium is a hypothetical annual premium which is based on the Specified Amount, Death Benefit option, Death Benefit Guarantee Period, any optional benefits, and characteristics of the Insured, such as factors including but not limited to Issue Age , sex, and underwriting classification. Please see “ Target Premium” in the Glossary of Terms.

The charges described in this table may vary based upon one or more characteristics of the Policy, such as factors including but not limited to: Insured underwriting classification, Issue Age, sex, underwriting amount, Specified Amount, Target Premium, Policy Debt, and Policy Year (see “Charges and Deductions— Monthly Policy Charges and Service Charges” in the Prospectus for more details regarding each charge). Charges may be different if your Policy is “Paid-up” (see “Other Benefits Available Under the Policy— Paid Up Insurance” in the Prospectus ). Therefore, the charges shown in the table may not be representative of the charges a particular Owner may pay. Your Policy schedule pages will indicate the Guaranteed Maximum Charge for each periodic charge under your Policy. In addition, where appropriate, all charges in the table expressed in dollars have been rounded to the nearest dollar, and all amounts that would round to zero have been rounded to the nearest penny or less, as necessary. Please request an illustration from your Financial Representative for personalized information, including the particular charges applicable to your Policy. (See “Illustrations” in the Prospectus). Unless otherwise noted, the charges in the table represent the monthly rate. Please see “Policy Anniversary” and “Policy Date” in the Glossary of Terms to help you understand how they will affect the charges applicable to your Policy.

The Cost of Insurance Charge will vary based on factors including but not limited to the Insured’s Attained Age, sex, underwriting classification, underwriting amount, and Policy Year. The Cost of Insurance Charges shown in the table may not be representative of the charges a particular Owner may pay. The net amount at risk is the difference between the Death Benefit and the Policy Value .

The Maximum Charge for the Cost of Insurance Charge assumes that the Insured has the following characteristic: Attained Age 120. Charges applicable to other combinations of Policy Year and Insured characteristics may be the same as the charge shown for the Maximum Charge for the Cost of Insurance Charge.

For the Minimum Charge for the Cost of Insurance Charge, the Current Charge assumes that the Policy is in the first Policy Year, and that the Insured has the following characteristics: Female, Issue Ages 1-10, Premier Non-Tobacco underwriting classification. For the Minimum Charge for the Cost of Insurance Charge, the Guaranteed Maximum Charge assumes that the Insured has the following characteristic: Female, Issue Ages 1-13, Premier Non-Tobacco underwriting classification. Charges applicable to other combinations of Policy Year and Insured characteristics may be the same as the charge shown for the Minimum Charge for the Cost of Insurance Charge.

Variable Universal Life Plus Prospectus

The amount of the Cost of Insurance Charge is determined by multiplying the net amount at risk by the cost of insurance rate (see “Charges and Deductions” in the Prospectus). The net amount at risk is the difference between the Death Benefit (or the Guaranteed Minimum Death Benefit if the Policy is in force under the Death Benefit Guarantee) and the Policy Value. Generally, the cost of insurance rate will increase each Policy Year.

For purposes of this charge, the Contract Fund Value is as of the day previous to a Monthly Processing Date plus investment results and interest credited applicable for that Monthly Processing Date . This charge may vary based on the proportionate amount of Contract Fund Value in the NM Strength and Stability Account (see “The Fixed Option” in the Prospectus) and/or different rates may apply to amounts in the Divisions versus amounts in the NM Strength and Stability Account.

The Maximum Charge for the Administrative Charge assumes that the Insured has the following characteristics: Issue Age 75, Class 1 to 9 Non-Tobacco/ Occasional Tobacco, Standard Plus Tobacco, and Class 1 to 7 Tobacco underwriting classification.

For the Maximum Charge for the Specified Amount Charge, the Current Charge and the Guaranteed Maximum Charge assumes that the Insured has the following characteristics: Issue Age 65, Class Preferred, Standard Plus and Class 1 to 7 Tobacco underwriting classification.

The Minimum Charge for the Specified Amount Charge, the Current Charge and the Guaranteed Maximum Charge assumes that the Insured has the following characteristics: Issue Age 15, Class Premier, Preferred Non-Tobacco/Occasional Tobacco underwriting.

This charge is deducted from Contract Fund Value when there is Policy Debt and is intended to cover the costs associated with loans. This charge, that has a guaranteed maximum rate of 2%, encompasses any loan interest spread, which is the difference between the interest rate charged on policy loan amounts and the interest rate credited on amounts designated as collateral for the loan. The interest rates charged to loan amounts and credited to collateral are adjustable but are subject to a guaranteed maximum difference of 2%. When the insured is at or above Attained Age 100, the current Policy Debt Expense Charge is 0.00%. Please see “Policy Loans” in the Prospectus for more information regarding how the loan interest rate is calculated.

The current minimum Specified Amount is $100,000 for Issue Ages 18-75 and $50,000 for Issue Ages 0-17.

The Maximum Charge for the Underwriting and Issue Charge assumes that the Insured has the following characteristics: Issue Age 25, Class 1 to 9 Non- Tobacco/Occasional Tobacco, Standard Plus Tobacco, and Class 1 to 7 Tobacco underwriting classification.

The Minimum Charge for the Underwriting and Issue Charge assumes that the Insured has the following characteristics: Issue Age 55, Premier, Preferred; and Standard Plus Non-Tobacco/Occasional Tobacco; Premier and Preferred Tobacco underwriting classification.

The charges for the Selected Monthly Premium Benefit vary based on the Insured’s Attained Age, underwriting classification, and “Selected Monthly Premium,” and may increase from year to year. Selected Monthly Premium is an amount the Owner selects subject to a maximum permitted amount. The charges shown in the table may not be representative of the charges a particular Owner may pay. If selected, the Selected Monthly Premium Benefit provides, during the total disability of the Insured , for the credit of the greater of (1) the Selected Monthly Premium or (2) the amount needed to provide for the credit of the “Specified Monthly Charges” (current Monthly Policy Charges excluding the Monthly Policy Debt Expense Charge and the charge for this benefit). (See “Other Benefits Available Under the Policy—Optional Benefits Available for a Charge” in the Prospectus for more information about this benefit.) The monthly charge for this benefit is the greater of the selected monthly premium rate times the Selected Monthly Premium or the specified monthly charges rate times the Specified Monthly Charges. If this optional benefit is selected, the maximum rates are shown in your Policy.

The Maximum Charge for the Selected Monthly Premium Benefit assumes that the Insured has the following characteristics: Attained Age 57, standard underwriting classification for Selected Monthly Premium and attained Age 59, standard underwriting classification for Specified Monthly Charges.

The Minimum Charge for the Selected Monthly Premium Benefit assumes that the Insured has the following characteristics: Attained Ages 0-17, standard underwriting classification. This assumes the amount of the charge determined by the Selected Monthly Premium is greater than the amount of the charge determined by the Specified Monthly Charges .

The charges for the Additional Purchase Benefit vary based on the Insured’s gender and Attained Age at the time the benefit is added to the Policy. The charges shown in the table may not be representative of the charges a particular Owner may pay. The maximum Additional Purchase Benefit amount is the lesser of two times the Specified Amount and $200,000.

The Current Charge for the Maximum Charge for the Additional Purchase Benefit Charge assumes that the Insured has the following characteristics: Male, Benefit added at Attained Age 13-14. The Guaranteed Maximum Charge for the Additional Purchase Benefit Charge assumes that the Insured has the following characteristics: Benefit added at Attained Age 38 for Male or Female.

The Current Charge for the Minimum Charge for the Additional Purchase Benefit Charge assumes that the Insured has the following characteristics: Female, Benefit added at Attained Age 30, 33, 36, and 38.
