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.

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.

Several investment companies have decided to impose redemption fees and/or transfer restrictions on certain plan and/or participant transactions.

Fixed-income and asset allocation investment options that invest in mortgage securities are subject to increased risk due to real estate exposure.
