Important Performance Information

Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the series' performance results would be less favorable. All results assume the reinvestment of dividends and capital gains. The performance is as of the date shown; it may not include the series' entire investment portfolio and is subject to change.

Initial Class shares have no sales charge.

The returns for the series shown do not reflect the deduction of expenses associated with variable products, such as mortality and expense risk charges, separate account charges, and sales charges imposed by insurance company separate accounts. Such expenses would reduce the overall returns shown. Please refer to the variable product's annual report for performance that reflects the deduction of the fees and charges imposed by insurance company separate accounts.

Withdrawals of earnings or other taxable amounts are subject to income tax and, if made prior to age 59 1/2, may be subject to an additional 10% federal tax penalty. Early withdrawals reduce the death benefit.

No representation is made, and no assurance can be given, that any investment's results will be comparable to the investment results of any other product with similar investment objectives and policies, including products with the same investment professional or manager. Differences in portfolio size, investments held, contract and portfolio expenses, and other factors can be expected to affect performance.

Important Risk Considerations

  • The series may not achieve its objective and/or you could lose money on your investment in the series.

  • Stock markets and investments in individual stocks are volatile and can decline significantly in response to issuer, market, economic, industry, political, regulatory, geopolitical, and other conditions.

  • Please see the prospectus for further information on these and other risk considerations.
