All investments are subject to market risk, including the possible loss of principal. The principal value of the target date funds is not guaranteed at any time, including, if applicable, at or after the target date, which is the approximate year an investor plans to retire (assumed to be age 65). Investments in other funds: The fund bears the risk that its underlying funds will fail to successfully employ their investment strategies. One or more underlying fund's underperformance or failure to meet its investment objective(s) as intended could cause the fund to underperform similarly managed funds. Interest rates: A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. International investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. Emerging markets: Investments in emerging market countries are subject to greater risk and overall volatility than investments in the U.S. and other developed markets. See the prospectus for more detail on the fund's principal risks.
