Contract Anniversary - each one-year anniversary of the Contract's Issue Date.

Contract Year - the succeeding twelve months from a Contract's Issue Date and every anniversary. The first Contract Year (Contract Year 0-1) starts on the Contract's Issue Date and extends to, but does not include, the first Contract Anniversary. Subsequent Contract Years start on an anniversary date and extend to, but do not include, the next anniversary date.

For example, if the Issue Date is January 15, 2025, then the end of Contract Year 0-1 would be January 14, 2026, and January 15, 2026, which is the first Contract Anniversary, begins Contract Year 1-2.

IMPORTANT INFORMATION YOU SHOULD CONSIDER ABOUT THE CONTRACT

FEES AND EXPENSES	LOCATION IN PROSPECTUS
Charges for Early Withdrawals	If you withdraw money from your Contract within 7 Complete Years following your last Premium payment, you will be assessed a withdrawal charge. The maximum withdrawal charge is 7% of the Remaining Premium withdrawn during the first Completed Year. For example, if you make an early withdrawal within the first Completed Year, you could pay a withdrawal charge of up to $7,000 on a $100,000 investment. The withdrawal charge then declines by 1% per year for each additional Completed Year, until the end of the seventh Completed Year, after which no charge is made.	Contract Charges- Transaction Expenses: Withdrawal Charge
Transaction Charges	In addition to withdrawal charges, you also may be charged for other transactions, such as when you transfer cash value between investment options more than 25 times a year, or if you request expedited delivery or wire transfer of funds.	Contract Charges- Transaction Expenses
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.

RISKS	Location in Prospectus
Risk of Loss	You can lose money by investing in this Contract.	Principal Risks
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. Withdrawal charges apply for up to 7 years following your last Premium payment. They will reduce the value of your Contract if you withdraw money during that time. The benefits of tax deferral and living benefit protections also mean the Contract is more beneficial to investors with a long time horizon.	Principal Risks
Risks Associated with Investment Options	•An investment in this Contract is subject to the risk of poor investment performance and can vary depending on the performance of the investment options you choose. •Each investment option (Investment Divisions and Fixed Account Options) has its own unique risks. •Early withdrawals from a Fixed Account Option are subject to a Market Value Adjustment. •You should review the investment options before making an investment decision.	Principal Risks
Insurance Company Risks	Any obligations (including under the Fixed Account Options), guarantees, and benefits of the Contract are subject to the claims-paying ability of Jackson. More information about Jackson is available upon request by visiting our website at www.jackson.com or by calling 1-800-644-4565.	Principal Risks
RESTRICTIONS
Investments	•We reserve the right to charge $25 for each transfer when you transfer money between Investment Divisions in excess of 25 times in a Contract Year. •Jackson may remove or substitute Funds as investment options available under the Contract, and may limit or suspend availability of the Fixed Account Options.	Principal Risks
Optional Benefits	•Certain benefits may limit withdrawals or other rights under the Contract. Under certain benefits, a withdrawal could reduce the value of a benefit by more than the dollar amount of the withdrawal. •Not all optional benefits are available through all broker-dealers and may vary by state or date of purchase. •We may modify or discontinue an optional benefit at any time.	Benefits Available Under the Contracts
TAXES
Tax Implications	•Consult with a tax professional to determine the tax implications of an investment in and purchase payments received under this Contract. •If you purchase the Contract through a tax-qualified plan or individual retirement account (IRA), you do not get any additional tax deferral. •Earnings on your Contract are taxed at ordinary income tax rates when you withdraw them, and you may have to pay a penalty if you take a withdrawal before age 59 ½.

CONFLICTS OF INTEREST

Accordingly, investment professionals may have a financial incentive to offer or recommend this Contract over another investment.	Distribution of Contracts
Exchanges	Some investment professionals may have a financial incentive to offer you a new contract in place of the one you own.
