Important Information You Should Consider About The Contract

An investment in the contract is subject to fees, risks, and other important considerations, some of which are briefly summarized in the following table. You should review the prospectus for additional information about these topics.


Fees, Expenses, and Adjustments				Location in Prospectus
Are There Charges or Adjustments for Early Withdrawals?	Yes. If you withdraw money from the contract during the first 4 contract years, you may be assessed a surrender charge of up to 4% of the premium withdrawn, declining to 0% over that time period. For example, if you make an early withdrawal, you could pay a surrender charge of up to $4,000 on a $100,000 investment. This loss will be greater if there are taxes or tax penalties.			Financial Information – Contract Costs and Expenses Expense Tables – Transaction Expenses
Are There Transaction Charges?	Yes. In addition to surrender charges, you also may be charged for the following transactions: transfers of cash value between investment options.			Financial Information – Contract Costs and Expenses Expense Tables – Transaction Expenses
Are There Ongoing Fees and Expenses?	Yes. The table below describes the fees and expenses that you may pay each year, depending on the investment options and optional benefits 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.

Risks			Location in Prospectus
Is There a Risk of Loss from Poor Performance?	Yes. You can lose money by investing in this contract, including loss of principal.		Variable Investment Options
Is this a Short-Term Investment?	No. This contract is not a short-term investment and is not appropriate for an investor who needs ready access to cash. Amounts withdrawn from the contract may result in surrender charges, taxes and tax penalties. Surrender charges may apply for the first 4 years following your last premium payment. Surrender charges will reduce the value of your contract if you withdraw money during that time. The benefits of tax deferral and living benefit protection also mean the contract is more beneficial to investors with a long time horizon.

How Are Investment Professionals Compensated?	Your investment professional may receive compensation for selling this contract to you, in the form of commissions, additional cash benefits (e.g., bonuses), and non-cash compensation. This conflict of interest may influence your investment professional to recommend continued investment in this contract over another investment for which the investment professional is not compensated or compensated less.	Your Rights and Responsibilities – Distribution of the Contract
Should I Exchange My Contract?	If you already own an insurance contract, some investment professionals may have a financial incentive to offer you a new contract in place of the one you own. You should only exchange a contract you already own if you determine, after comparing the features, fees, and risks of both contracts, and any fees or penalties to terminate your existing contract, that it is better for you to purchase the new contract rather than continue to own your existing contract.
