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.

Returns represent past performance and do not guarantee future results. Share price, principal value, and return will vary and you may have a gain or loss when shares are sold. Current performance may be lower or higher than quoted. For more performance information, including the most recent month-end performance, visit principal.com.

Investment and Insurance products are: * Not insured by the FDIC or Any Federal Government Agency * Not a Deposit or Other Obligation of, or Guaranteed by Credit Union or Bank * Subject to Investment Risks, Including Possible Loss of the Principal Amount Invested Investing involves risk, including possible loss of principal. 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. For a personalized illustration of historical performance, which reflects the cost of insurance protection, contact your registered representative. This material is authorized for distribution to prospective investors only when preceded or accompanied by a current prospectus for the Variable Universal Life product or Variable Annuity product and the underlying investment options.

International and global investing involves greater risks such as currency fluctuations, political/social instability and differing accounting standards. Equity investment options involve greater risk, including heightened volatility, than fixed-income investment options. Fixed-income investment options are subject to interest rate risk, and their value will decline as interest rates rise. Asset allocation does not guarantee a profit or protect against a loss. Investing in real estate, small-cap, international, and high-yield investment options involves additional risks. The Investment Advisor will display "Multiple Sub-Advisors" for certain target-date, target-risk and specialty investment options where the assets are directed by the Investment Manager to multiple underlying investment options. These underlying investment options may use multiple sub-advisors who are responsible for the day-to-day management responsibilities. Asset allocation and diversification do not ensure a profit or protect against a loss. Additionally there is no guarantee this investment option will provide adequate income at or through retirement. These calculated returns reflect the historical performance of the oldest share class of the fund, adjusted to reflect a portion of the fees and expenses of this share class. For time periods prior to inception date of the fund, predecessor performance is reflected. Please see the fund's prospectus for more information on specific expenses, and the fund's most recent shareholder report for actual date of first sale. Expenses are deducted from income earned by the fund. As a result, dividends and investment results will differ for each share class. Fixed-income and asset allocation investment options that invest in mortgage securities are subject to increased risk due to real estate exposure.
