IMPORTANT INFORMATION YOU SHOULD CONSIDER ABOUT THE CONTRACT

FEES AND EXPENSES
Charges for Early Withdrawals	If the Investor withdraws money from the Contract within ten (10) completed Purchase Payment Periods, the Investor can be assessed an early withdrawal charge equal to a maximum of 5% of the amount withdrawn. The specified maximum percentage referenced in the preceding sentence applies to withdrawals from Installment Purchase Payment Contracts and the withdrawal charge schedule that applies to that account, but it will never exceed 8.50% of total Purchase Payments. For example, if you make an early withdrawal from an Installment Purchase Payment Contract, you could pay a surrender charge of up to $5,000 on a $100,000 investment. Please also note that withdrawals from the Guaranteed Accumulation Account are subject to a Market Value Adjustment, which can be either positive or negative (see Appendix B to the full Contract prospectus). See “FEE TABLE - Transaction Expenses” and “CHARGES AND FEES - Transaction Fees - Early Withdrawal Charge” in the full Contract Prospectus.
Transaction Charges	In addition to the early withdrawal charge, the Investor may also be charged for other transactions: • For transferring or reallocating Account Value among the investment options; • Certain Funds may impose redemption fees as a result of withdrawals, transfers or other Fund transactions you may initiate; and • Charges for advisory services due to an independent advisory services agreement between you and an investment advisor may be deducted from Contract value. See “FEE TABLE - Transaction Expenses” and “CHARGES AND FEES - Transaction Fees” in the full Contract Prospectus.

FEES AND EXPENSES (continued from previous page)
Ongoing Fees and Expenses (annual charges)	The table below describes the fees and expenses that you may pay each year, depending on the options you choose. 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. These ongoing fees and expenses do not reflect any advisory fees due under an independent advisory services agreement with a participant, and if such charges were reflected, these ongoing fees and expenses would be higher.
	Annual Fee	Minimum		Maximum
	Base Contract Expenses	1.25%¹^{, 2}		% ^{1, 2}
	Investment options (Portfolio company fees and expenses)	0.34%³		1.25%³
	Because your Contract is customizable, the choices you make affect how much you will pay. To help you understand the cost of owning your Contract, the following table shows the lowest and highest cost you could pay each year based on current charges. This estimate assumes that you do not take withdrawals from the Contract, which could add early withdrawal charges that substantially increase costs.
	Lowest Annual Cost Estimate: $$2,380		Highest Annual Cost Estimate: $$5,647
	Assumes: • Investment of $100,000; • 5% annual appreciation; • No optional benefits; • Fees and expenses of least expensive Fund; • No sales charges or advisory fees; and • No additional Purchase Payments, transfers or withdrawals.

¹ As a percentage of average Account Value.

² The Base Contract Expenses include (1) the mortality and expense risk charge of $1.25, which compensates us for the mortality and expense risks we assume under the Contract, including those risks associated with our promise to make lifetime Income Phase payments; and; (2) a $20 annual maintenance fee converted to an annual percentage equal to -%. The annual maintenance fee may be reduced or eliminated in certain circumstances. The minimum amount reflects this reduction or elimination, while the maximum amount does not. Additionally, we currently do not impose the administrative expense charge, although we reserve the right to do so. The maximum amount includes the 0.25% administrative expense charge, while the minimum amount does not. See “CHARGES AND FEES - Periodic Fees and Charges” in the full Contract Prospectus.

³ These expenses, which include management fees, distribution (12b-1) and/or service fees and other expenses, do not take into account any fee waiver or expense reimbursement arrangements that may apply. These expenses are for the year ended December 31, 2023, and will vary from year to year.

RISKS (continued from previous page)
Not a Short-Term Investment	This Contract is not designed for short-term investing and is not appropriate for an Investor who needs ready access to cash. The Contract is typically most useful as part of a personal retirement plan. Early withdrawals may be restricted by the Tax Code or your plan and may expose you to early withdrawal charges or tax penalties. You should not participate in this Contract if you are looking for a short-term investment or expect to make withdrawals before you are age 59½. See “PRINCIPAL RISKS OF INVESTING IN THE CONTRACT” in the full Contract Prospectus.
Risks Associated with Investment Options	An investment in the Contract is subject to the risk of poor investment performance and can vary depending on the performance of the investment options available under the Contract. Each investment option (including the Guaranteed Accumulation Account and the other Fixed Interest Options) will have its own unique risks, and you should review these investment options before making an investment decision. If all or a portion of your Account Value in the Guaranteed Accumulation Account is withdrawn, you could experience a loss as to the amount invested in that account. See ‘THE INVESTMENT OPTIONS - The Variable Investment Options” and APPENDIX A, APPENDIX B, APPENDIX C and APPENDIX D in the full Contract Prospectus and “APPENDIX: FUNDS AVAILABLE UNDER THE CONTRACT” to this summary prospectus.
Insurance Company Risks	An investment in the Contract is subject to the risks related to VRIAC, including that any obligations, including under the Fixed Interest Options, guarantees or benefits are subject to the financial strength and claims-paying ability of VRIAC. More information about VRIAC, including its financial strength and claims paying ability, is available upon request, by contacting Customer Service at 1-800-584-6001. See “THE CONTRACT - The General Account” in the full Contract Prospectus.
RESTRICTIONS
Investment Options	• Some Subaccounts and Fixed Interest Options may not be available through certain Contracts, your plan or in some states. See your Contract or certificate for any state specific variations; • Not all Fixed Interest Options may be available for current or future investment; • There are certain restrictions on transfers from the Fixed Interest Options; • The Company reserves the right to combine two or more Subaccounts, close Subaccounts or substitute a new Fund for a Fund in which a Subaccount currently invests; and • The Contract is not designed to serve as a vehicle for frequent transfers. We actively monitor Fund transfer and reallocation activity to identify violations of our Excessive Trading Policy. Electronic trading privileges will be suspended if the Company determines, in its sole discretion, that our Excessive Trading Policy has been violated. See “THE INVESTMENT OPTIONS - Selecting Investment Options and Right to Change the Separate Account” and “THE CONTRACT - Limits on Frequent or Disruptive Transfers” in the full Contract Prospectus.
Optional Benefits	• We may discontinue or restrict the availability of an optional benefit; • Benefits available to you may vary based on employer and state approval. Participants should refer to their plan documents for available benefits; and • If a participant elects to pay advisory fees from the Variable Investment Options, such deductions will reduce the death benefit amount and also may be subject to federal and state income taxes and a 10% federal tax penalty. See “SYSTEMATIC DISTRIBUTION OPTIONS - Availability of Systematic Distribution Options” in the full Contract Prospectus.

TAXES
Tax Implications	• You should consult with a tax and/or legal adviser to determine the tax implications of an investment in, and distributions received under, the Contract; • There is no additional tax benefit to the Investor if the Contract is purchased through a tax-qualified plan or individual retirement account (“IRA”); and • Withdrawals will be subject to ordinary income tax and may be subject to tax penalties. See “FEDERAL TAX CONSIDERATIONS” in the full Contract Prospectus.
CONFLICTS OF INTEREST
Investment Professional Compensation	Although the Contracts are no longer offered for new sales, firms and their registered representatives that sold the Contract may receive commissions on additional Purchase Payments paid. This compensation is not paid directly by Contract Holders or the Separate Account. This compensation could influence your investment professional to recommend keeping the Contract. See “OTHER TOPICS - Contract Distribution” in the full Contract Prospectus.
Exchanges	Some investment professionals may have a financial incentive to offer you a new contract in place of the one you own. You should exchange your Contract only if you determine, after comparing the features, fees and risks of both contracts, that it is preferable for you to purchase the new contract rather than continue to own the existing Contract. See “PRINCIPAL RISKS OF INVESTING IN THE CONTRACT” in the full Contract Prospectus.
