Investors should carefully consider a fund's investment objectives, risks, charges, and expenses prior to investing.

Investment results shown represent historical performance and do not guarantee future results. Your mutual fund's returns and principal values will fluctuate with changes in interest rates and other market conditions so the value, when redeemed, may be worth more or less than original costs. Current performance may be lower or higher than the performance shown.

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 mutual fund. Performance shown reflects the application of net expenses of the fund.

Price The price, or net asset value is the value of mutual fund shares determined by deducting the fund's liabilities from the total assets of the portfolio and dividing this amount by the number of shares outstanding. This cannot be relied upon as today's offering price.

YTD at NAV % - Measured from January 1, 2020 to the most recent established NAV date. Returns include the reinvestment of dividends and capital gains distributions at NAV.

Average Annual Total Return at Maximum Offering Price (MOP) - The highest price that may be charged for purchases of fund shares, including the maximum contingent deferred sales charge or the maximum front end sales charge, whichever is applicable. Returns include the reinvestment of dividends and capital gains distributions at NAV as of previous month end or previous quarter end.

Morningstar Ratings are as of previous month end.

Since Inception return represents Average Annual Total Return at Maximum Offering Price (MOP) from Extended Performance Inception Date as of previous month end or previous quarter end.

Contingent Deferred Sales Charge (CDSC) - A deferred sales charge, which is paid at the time of redemption and generally decreases with the amount of time that fund shares are held before sale, ultimately declining to 0%. It is referred to as a contingent sales charge because of such declining schedule. The CDSC is also commonly called a back-end load. Performance displayed reflects the application of these charges.

The 7-Day Yield % more closely reflects the current earnings of this money market investment option than the total return displayed.

Morningstar Ratings do not reflect the inclusion of sales charges. If sales charges were reflected, rankings could be lower.

The Morningstar Rating™ for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.

1 Small-cap and mid-cap investment options are subject to more fluctuation in value and may have additional risks than other investment options with stocks of larger, more stable companies.


2 Each index based investment option is invested in the stocks or bonds of the index it tracks. Performance of indexes reflects the unmanaged results for the market segment the selected stocks or bonds represent. There is no assurance an index based investment option will match the performance of the index tracked.


3 International and global investment options are subject to additional risk due to fluctuating exchange rates, foreign accounting and financial policies, and other economic and political environments.


4 High yield investment options are subject to greater credit risk and volatility that is associated with high yield bonds.


5 Real Estate investment options are subject to investment and liquidity risk and other risks inherent in real estate such as those associated with general and local economic conditions. Property values can decline due to environmental and other reasons. In addition, fluctuation in interest rates can negatively impact the performance of real estate investment options.

Risks associated with preferred securities differ from risks inherent with other investments. In particular, in the event of bankruptcy, a company's preferred securities are senior to common stock but subordinated to all other types of corporate debt.

In addition, securities such as bonds, equities, commodities, international and emerging market securities, and currencies are used to implement the investment strategy. These investments are subject to risks associated with market and interest rate movements. The fund is considered non-diversified which may make it more susceptible to price volatility if the fund does not meet its objective. Due to the nature of the investment process, investors should not expect significant outperformance during market rallies. Additional risks are included in the funds prospectus. It is possible to lose money when investing in the fund.


28 The risks associated with derivative investments include that the underlying security, interest rate, market index, or other financial asset will not move in the direction the Investment Adviser and/or Sub-Advisor anticipated, the possibility that there may be no liquid secondary market, the risk that adverse price movements in an instrument can result in a loss substantially greater than a fund's initial investment, the possibility that the counterparty may fail to perform its obligations; and the inability to close out certain hedged positions to avoid adverse tax consequences.


29 International and global investing involves greater risks such as currency fluctuations, political/social instability and differing accounting standards.

The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.


31 Fixed-income investment options are subject to interest rate risk, and their value will decline as interest rates rise. Risks of preferred securities differ from risks inherent in other investments. In particular, in a bankruptcy preferred securities are senior to common stock but subordinate to other corporate debt. Contingent capital securities (CoCos) may have substantially greater risk than other securities in times of financial stress. An issuer or regulators decision to write down, write off or convert a CoCo may result in complete loss on an investment.


33 Additional target date portfolios may be added to the Principal LifeTime portfolios series to accommodate plan participants with later normal retirement dates as they enter the workforce. Participants may also choose a portfolio with a target date that does not match the intended retirement date. Compare the different portfolios to see how the mix of investments might shift.


34 This investment option is considered non-diversified, which means it, or the underlying mutual fund, can invest a higher percentage of its assets in of fewer individual issuers than a diversified investment. As a result, changes in the value of a single investment could cause greater fluctuations, gain or loss, in the net asset value than would occur if it was more diversified.


35 Selecting a target date fund series is also authorizing any additional vintage which is launched by the investment provider for the series, and included in their associated materials, to be added to the plan after proper notification.


36 There is no guarantee that a target date investment will provide adequate income at or through retirement. A target date fund's (TDF) glidepath is typically set to align with a retirement age of 65, which maybe your plan's normal retirement date (NRD). If your plan's NRD/age is different, the plan may default you to a TDF based on the plans NRD/Age. Participants may choose a TDF that does not match the plan's intended retirement date but instead aligns more to their investment risk. Compare the different TDF's to see how the mix of investments shift based on the TDF glide path.
