Total Returns

Returns shown for periods of less than one year are not annualized. All returns displayed here are after Total Investment Expense of the investment option.

The Year-to-Date Change represents an unannualized rate of return (change in value) since the start of the year. All returns shown here are after the Total Investment Expense of the investment option.

In situations where the net and gross fund expense figures are different, the investment manager has contractually agreed to limit the investment option's expense. Differences may also be shown due to the investment manager choosing to pay certain expenses that would normally be payable by the fund. The gross fund expense figure does not reflect any waivers or caps on the fund. Performance when shown reflects the application of net expenses of the fund.

The investment results shown represent historical returns based upon the assumption variable universal life insurance products and variable annuity products were available for the periods shown. Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data shown. Since the investment results and unit values of the divisions will fluctuate, the policy's accumulated value may at any time be more or less than the total premiums paid under the contract, including upon surrender of the contract. For more performance information, including the most recent month-end performance, please contact 800-247-9988 for variable life products or 800-852-4450 for variable annuity products.

Fees and expenses are only one of several factors that participants and beneficiaries should consider when making investment decisions. The cumulative effect of fees and expenses can substantially reduce the growth of a participant's or beneficiary's retirement account. Participants and beneficiaries can visit the Employee Benefit Security Administration's website for an example demonstrating the long-term effect of fees and expenses. Returns shown reflect all investment management charges and any miscellaneous expenses incurred by the underlying accounts of the divisions. Returns do not include premium expense charges and various monthly deductions (administration charges, cost of insurance, and mortality and expense risks charges) which vary by contract. In addition, results do not reflect the premium expense charge or the surrender charge levied if the policy is surrendered during the first 10 policy years, or within 10 years after a face amount increase. If these fees and charges had been deducted, the results shown would be significantly lower. These charges are explained fully in the prospectus and their effect upon cash surrender values are best explained by reviewing several hypothetical illustrations contained in the prospectus.
