Is There a Risk of Loss from Poor Performance?

Yes. You can lose money by investing in this Contract.

Summary - Risks of the Policy

Is this a Short-Term Investment?

No. This Contract is not designed for short-term investing and is not appropriate for an investor who needs ready access to cash. The benefits of tax deferral and living benefit protections also mean the Contract is more beneficial to investors with a long time horizon.

Summary - Risks of the Policy

What Are the Risks Associated with the 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 (including the Fixed Account) has its own unique risks. •You should review the investment options before making an investment decision. •Your contract could lapse and terminate if there is poor investment performance and or if the Net Accumulated Value becomes too low to support the policy's monthly charges. Policy loans or partial surrenders also increase the risk that your contract may lapse. There may be a cost associated with reinstating a lapsed contract and the payability of death benefits may be impacted in the event of the contract lapsing.
