Overview of the Contract

Purpose of the Contract — The Contract is a variable annuity contract. It is designed for retirement planning purposes. You make investments in the Contract’s investment options during the accumulation phase. The value of your investments is used to calculate your benefits under the Contract. At the end of the accumulation phase, we use that accumulated value to calculate the payments that we make during the annuity phase. These payments can provide or supplement your retirement income. Generally speaking, the longer your accumulation phase, the greater your accumulated value may be for setting your benefits and annuity payouts. The Contract also includes a death benefit to help financially protect your Designated Beneficiary.

This Contract may be appropriate for you if you have a long investment time horizon. Each Purchase Payment is subject to a withdrawal charge for eight years from the date of the first Purchase Payment. This means that all Purchase Payments will be subject to a withdrawal charge until Contract Year 9. Because of the withdrawal charge and the possibility of income tax and tax penalties on early withdrawals, the Contract should not be viewed as an investment vehicle offering low-cost liquidity. Your financial goal in acquiring the Contract should focus on a long-term insurance product, offering the prospect of investment growth.

Phases of the Contract — The contract has two phases: (1) an accumulation phase (for savings) and (2) an annuity (payout) phase (for income).

Accumulation Phase. During the accumulation phase, earnings accumulate on a tax-deferred basis and are taxed as income when you make a withdrawal. To accumulate value during the accumulation phase, you invest your Purchase Payments and earnings in the Subaccounts that are available under the Contract, which, in turn, invest in Underlying Funds with different investment strategies, objectives, and risk/reward profiles. You may allocate all or part of your Purchase Payments and Contract Value to the Subaccounts. Amounts that you allocate to a Subaccount will increase or decrease in dollar value depending in part on the investment performance of the Underlying Fund in which such Subaccount invests. The Fixed Account option (if available under your Contract), which guarantees the principal and a minimum interest rate, may also be available for investment. If the Fixed Account is available under

your Contract, you may allocate all or part of your Purchase Payments to the Fixed Account, which is part of the Company's General Account.

Additional information about the Underlying Funds currently available under the Contract and the Fixed Account (if available) is provided in Appendix A: Investment Options Available Under the Contract.

Annuity (Payout) Phase. The Annuity phase occurs after the Annuity Commencement Date and is when you or a designated payee begin receiving regular Annuity payments from your Contract. The Contract provides several Annuity Options. You should carefully review the Annuity Options with your financial or tax adviser. The payments may be fixed or variable or a combination of both. Variable payments will vary based on the performance of the Subaccounts you select. Unless you direct otherwise, proceeds derived from Contract Value allocated to the Subaccounts will be applied to purchase a variable annuity and proceeds derived from Contract Value allocated to the Fixed Account will be applied to purchase a fixed annuity.

Please note that if you annuitize, your investments will be converted to income payments and you generally will no longer be able to withdraw money at will from your Contract. However, under Annuity Options 5 through 9, withdrawals (other than systematic withdrawals) are permitted after the Annuity Commencement Date.

Contract Features —

Accessing Your Money. Before your Contract is annuitized, you can withdraw money from your Contract at any time. If you take a withdrawal, you may have to pay a surrender charge and/or income taxes, including a tax penalty, if you are younger than age 59½.

Tax Treatment. You can transfer money between investment options without tax implications, and earnings (if any) on your investments are generally tax-deferred. You are taxed only upon: (1) making a withdrawal; (2) surrender of the Contract; (3) receiving a payment from us; or (4) payment of a death benefit.

Death Benefit. For Contract Owners aged 75 or younger on the Contract issue date, the Contract includes a standard death benefit that will pay the greatest of total Purchase Payments (adjusted for any outstanding Contract Debt, any pro rata account administration charge, prior withdrawals, including any withdrawal charges, and any uncollected premium tax), the Contract Value, or the stepped-up death benefit. The stepped-up death benefit is the largest death benefit on any Contract anniversary that is a multiple of six that occurs prior to the oldest Owner or Annuitant attaining age 76, plus Purchase Paymentsand less withdrawals made since the applicable Contract anniversary. For Contract Owners aged 76 and older on the Contract issue date, the standard death benefit will be the greater of the Contract Value or total Purchase Payments (adjusted for any outstanding Contract Debt, any pro rata account administration charge, prior withdrawals, including any withdrawal charges, and any uncollected premium tax).

Loans. If you own a Contract issued in connection with a retirement plan that is qualified under Section 403(b) of the Internal Revenue Code, you may be able to borrow money under your Contract using the Contract Value as the only security for the loan. If a loan is taken it must be repaid prior to the Annuity Commencement Date. A loan must be taken and repaid prior to the Annuity Commencement Date.

Advisory Fees. Deductions from your Contract Value to pay third-party advisory fees are treated as withdrawals under the Contract, but no surrender charge (if applicable) is assessed on such withdrawals, and the deduction of advisory fees will not count toward the annual free withdrawal amount. If you elect to pay advisory fees from your Contract Value, then the deduction will reduce the death benefits and other guaranteed benefits, perhaps significantly, and may be subject to federal and state income taxes and a 10% federal penalty tax.

Additional Services — We offer several additional services:

Dollar Cost Averaging. You direct us to systematically transfer Contract Value among the Subaccounts and the Fixed Account (if available) on a monthly, quarterly, semiannual, or annual basis.

Asset Reallocation Option. You direct us to automatically reallocate your Contract Value to return to your original percentage investment allocations on a periodic basis.

Systematic Withdrawals. After the first Contract Year, or during the first Contract Year if your Contract Value is $40,000, you receive regular automatic withdrawals from your Contract, on a monthly, quarterly, annual or semi-annual basis, provided that each payment must amount to at least $25 (unless we consent otherwise).

Buying the Contract

If you wish to purchase a Contract, you may submit an application and an initial Purchase Payment to the Company, as well as any other form or information that the Company may require. The Company reserves the right to reject an application or Purchase Payment for any reason, subject to the Company’s underwriting standards and guidelines and any applicable state or federal law relating to nondiscrimination.

Your initial Purchase Payment must be at least $500 for a Contract funding a Non-Qualified Plan or Group Unallocated Contract, $25 for a Contract funding a Qualified Plan and $2,500 for single purchase payment immediate annuity. Thereafter, you may choose the amount and frequency of Purchase Payments, except that the minimum subsequent Purchase Payment is $25. The Company does not permit subsequent Purchase Payments for a single purchase payment immediate annuity. The Company will not accept, without prior Company approval, aggregate Purchase Payments in an amount that exceeds $1,000,000 under any variable annuity contract(s) issued by the Company for which you are an Owner and/or Joint Owner. Subsequent Purchase Payments under a Qualified Plan may be limited by the terms of the plan and provisions of the Internal Revenue Code. The Company has the right to refuse any Purchase Payment.

The Company will apply the initial Purchase Payment no later than the end of the second Valuation Date after the Valuation Date it is received by the Company, in good order. In this regard “good order” means that the Purchase Payment is preceded or accompanied by an application that contains sufficient information to establish an account and properly credit such Purchase Payment. Sometimes the Purchase Payment is not preceded by or accompanied by a complete application. The application includes your affirmative consent permitting the Company to hold your initial Purchase Payment beyond five Valuation Dates in its effort to complete your application. If your application is incomplete, and the Company is unable to resolve the problem within five Valuation Dates, the Company will notify

you of the reasons for the delay. If you affirmatively revoke the consent given with your application to hold your initial Purchase Payment pending resolution of the problem, we will return your Purchase Payment. Otherwise, the Purchase Payment will be applied not later than the second Valuation Date after the Valuation Date the problem is resolved.

The Company will credit subsequent Purchase Payments received in good order as of the end of the Valuation Date on which they are received by the Company; however, subsequent Purchase Payments received at or after close of a Valuation Date (normally 3:00 p.m. Central time) will be effected at the Accumulation Unit value determined on the following Valuation Date.

In an application for a Contract, you select the Subaccounts and/or the Fixed Account to which Purchase Paymentss will be allocated. Purchase Paymentss will be allocated according to your instructions contained in the application or more recent instructions received, if any, except that no Purchase Payments allocation is permitted that would result in less than $25.00 per payment being allocated to any one Subaccounts.

Making Withdrawals: Accessing the Money in Your Contract

Full and Partial Withdrawals — An Owner may make a partial withdrawal of Contract Value, or surrender the Contract for its Withdrawal Value. Surrender and withdrawal payments will generally be mailed within seven days after we receive the request. A full or partial withdrawal, including a systematic withdrawal, may be taken from the Contract Value at any time while the Owner is living and before the Annuity Commencement Date, subject to limitations under applicable law. After the Annuity Commencement Date, withdrawals are only permitted under certain Annuity Options. No surrender charges will be assessed on a withdrawal from your Contract Value to pay advisory fees, and the deduction of advisory fees will not count toward the annual free withdrawal amount. Withdrawals to pay advisory fees may be subject to federal and state income taxes and a 10% federal penalty tax. See "The Contract - Withdrawals to Pay Advisory Fees" in the Prospectus.

A full or partial withdrawal request will be effective as of the end of the Valuation Period that it is received by the Company at its Administrative Office; however, if it is received on a Valuation Date at or after the close of a Valuation Date (normally 3:00 p.m. Central time), the withdrawal will be effected at the Accumulation Unit value determined on the following Valuation Date. In addition, a withdrawal will not be processed unless it is accompanied by a properly completed Withdrawal Request form (including the Owner's signature and the written consent of any effective assignee or irrevocable beneficiary, if applicable).

The proceeds received upon a full withdrawal will be the Contract’s Withdrawal Value. The Withdrawal Value is equal to the Contract Value as of the end of the Valuation Period during which the withdrawal is processed, less any outstanding Contract Debt, any applicable withdrawal charge, a pro rata account administration charge and any uncollected premium taxes.

A partial withdrawal may be requested for a specified percentage or dollar amount of Contract Value. Partial withdrawals (including systematic withdrawals) will result in a payment of the amount specified in the partial withdrawal request less any applicable withdrawal or premium tax charge. Any withdrawal charge on partial withdrawals (including systematic withdrawals) from Purchase Payments before the 9th Contract Year will be deducted from the requested payment amount, as will any premium tax charge. Alternatively, you may request that any withdrawal and/or premium tax charge be deducted from your remaining Contract Value, provided there is sufficient Contract Value available. No partial withdrawal will be processed which would result in the withdrawal of Contract Value from the Loan Account. The Company will deduct the amount of a partial withdrawal from the Contract Value in the Subaccounts and the Fixed Account, according to the Contract owner’s instructions to the Company. If a Contract owner does not specify the allocation, the Company will deduct the withdrawal in the same proportion that the Contract Value is allocated among the Subaccounts and the Fixed Account.

There may be tax implications when you take out money, including a 10% penalty tax if the withdrawal is made prior to age 59½, and withdrawals may have a negative impact on certain benefits and guarantees that you may elect. Withdrawals may significantly reduce the value of or even terminate the benefit. Depending on the circumstances, the Internal Revenue Code or your retirement plan may restrict your ability to take withdrawals.

The deduction of advisory fees from your Contract Value is treated as a withdrawal under the Contract, but no surrender charges will be assessed on a withdrawal to pay advisory fees and the deduction of advisory fees will not count toward the annual free withdrawal amount. Withdrawals to pay advisory fees may still be treated as withdrawals for tax purposes by the Company and/or the IRS. For Non-Qualified Contracts, all or a portion of the charges deducted from your Contract Value to pay advisory fees to a financial intermediary may be subject to federal and state income taxes and a 10% federal penalty tax. See “Charges and Deductions – Deduction of Advisory Fees” in the Prospectus.

If a partial withdrawal (other than a systematic withdrawal) is requested after the first Contract Year that would leave the Withdrawal Value in the Contract less than $2,000, the Company reserves the right to terminate the Contract and pay the Contract Value in one sum to the Owner. However, the Company will first notify the Owner that the Contract is subject to termination and will only terminate the contract if, after 90 days following the date of the notice, the Owner has not made any Purchase Payments to increase the Withdrawal Value to $2,000.

Additional Information About Fees

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

The first table describes the fees and expenses that you will pay at the time that you buy the Contract, surrender or make withdrawals from an Investment Option or from the Contract, or transfer Contract Value between Investment Options. State premium taxes may also be deducted. The fees and expenses do not reflect any advisory fees paid to financial intermediaries from your Contract Value or other assets. If such charges were reflected, the fees and expenses would be higher.

Transaction Expenses

	Charge
Sales Load on Purchase Payments	None
Maximum Surrender Charge (as a percentage of amount withdrawn attributable to Purchase Payments)	8%1
Transfer Processing Fee (per transfer)	None
1 We also refer to this charge as a contingent deferred sales charge, withdrawal charge, and sales charge. The amount of the surrender charge is determined by reference to the Contract Year in which the withdrawal is made. Withdrawals in the first Contract Year are subject to a charge of 8% declining to 0% in Contract Year nine and later. The eight year contingent deferred sales charge schedule is different for the Variflex Contract – 401(k) and 408(k) and for a Contract issued to a Participant under a Section 403(b) retirement plan sponsored by an institution of higher education as defined in the Texas Education Code. See “Contingent Deferred Sales Charge” and “Withdrawal Charge for Certain Texas Participants” for more information.

The next table describes the fees and expenses that you will pay each year during the time that you own the Contract (not including Underlying Fund fees and expenses).

Annual Contract Expenses

	Charge
Administrative Expenses	$30.001
Net Loan Interest Charge2	2.50%
Base Contract Expenses (as a percentage of average Contract Value)3	1.20%
1 We call this the account administration charge in your Contract, as well as in other places in the Prospectus. An account administration charge of $30 (or if less, 2% of Contract Value for the Variflex Contract – 401(k) and 408(k)) is deducted at each Contract anniversary, and a pro rata account administration charge is deducted: (1) upon full withdrawal of Contract Value; (2) upon the Annuity Commencement Date if one of Annuity Options 1 through 4, 9 or 10 is elected; (3) upon payment of a death benefit; and (4) the first deduction of the account administration charge if the Contract has been in force for less than a full calendar year. The account administration charge will be waived if your Contract Value is $25,000 or more and your Contract has been in force eight or more years on the date the charge is to be deducted. This fee is presented as part of the Base Contract Expenses in the section entitled “Important Information You Should Consider About Your Contract” in the Prospectus. 2 The net loan cost equals the difference between the amount of interest the Company charges you for a loan, which is 5.5% (5.0% if your Contract was issued on or after January 4, 1999) and the amount of interest the Company credits to the Loan Account, which is 3.0%. 3 This charge is comprised of the annual mortality and expense risk charge of 1.20%, which is deducted daily. The Company guarantees that the charge for mortality and expense risks will not exceed an annual rate of 1.20% of each Subaccount’s average daily net assets. The mortality and expense risk charge also applies during the Annuity Period.

The next table below shows the minimum and maximum total operating expenses charged by the Underlying Funds that you may pay periodically during the time that you own the Contract. Expenses shown may change over time and may be higher or lower in the future. A complete list of Underlying Funds

available under the Contract, including their annual expenses, may be found in Appendix A to this Initial Summary Prospectus.

Annual Underlying Fund Expenses

	Minimum	Maximum
Annual Underlying Fund Expenses (expenses deducted from Underlying Fund assets include management fees, distribution (12b-1) fees, service fees and other expenses)	0.63%	3.38%
Net Annual Underlying Fund Expenses (after contractual waivers/reimbursements)1	0.63%	3.19%
1 Certain of the Underlying Funds have entered into contractual expense waiver or reimbursement arrangements that reduce fund expenses during the period of the arrangement. These arrangements vary in length and are in place at least through April 30, 2027.

Examples — These Examples are intended to help you compare the cost of investing in the Subaccounts with the cost of investing in other annuity contracts that offer Variable Options. These costs include transaction expenses, Annual Contract Expenses and annual Underlying Fund fees and expenses but do not include state premium taxes, which may be applicable to your Contract. The Examples do not reflect any advisory fees paid to financial intermediaries from your Contract Value or other assets. If such fees were reflected, the costs would be higher.

The Example assumes all Contract value is allocated to the Subaccounts. Your costs could differ from those shown below if you invest in the Fixed Account (if available).

These Examples assume that you invest $100,000 in the Subaccounts for the time periods indicated. The Examples also assume that your investment has a 5% return each year. The first Example assumes the most expensive Annual Underlying Fund Expenses. The second Example assumes the least expensive Annual Underlying Fund Expenses. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

If you surrender your Contract at the end of the applicable time period	$11,822.48	$19,330.62	$26,884.70	$46,907.80
