Investment results shown represent historical performance and do not guarantee future results. Investment returns and principal values 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 data shown. Please see the Fact Sheet for a specific fund’s performance calculated by the retroactive application of the current asset allocation methodologies.

In situations where the net and gross total investment expense figures are different, the collective investment trust or the underlying investment options in which a collective investment trust invests have waived/caped a portion of its management fee through the date displayed in the waiver expiration date or contractual cap expiration date column. Differences may also be shown due to the fund family choosing to pay certain expenses that would normally be payable by the fund. Returns displayed are based on net total investment expense.

Footnotes:

 1. 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.
 2. Fixed-income and asset allocation investment options that invest in mortgage securities are subject to increased risk due to real estate exposure.
 3. 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. Additionally there is no guarantee this investment option will provide adequate income at or through retirement.
 4. 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.
