Investing in financial markets involves risks. Investors may lose money. Our investment strategies cannot ensure a profit or protect against loss. There are many factors that affect future risks and returns that we are unable to anticipate. Past performance does not guarantee future results, which may be materially worse.

Forecasting models may do a poor job of describing actual market outcomes and any estimates of expected returns, including efforts to achieve a particular return for a given level of risk, are inherently uncertain and may not be realized. Strategies that are intended to replicate the performance of target-date funds may not achieve this goal and may produce materially worse results.
