Morningstar rated the Equity Index 500 Fund among 1772, 1772, 1376 and 709 Large Blend funds for the overall rating and the 3-, 5-, and 10-year periods (as applicable) ending 01/31/2010, respectively. Morningstar Ratings™ are based on risk-adjusted returns. The Overall Morningstar Rating™ is derived from a weighted average of the performance figures associated with a fund's 3-, 5-, and 10-year (if applicable) Morningstar Rating™ metrics.
1 For funds with at least a 3-year history, a Morningstar Rating™ is based on a risk-adjusted return measure (including the effects of sales charges, loads, and redemption fees) with emphasis on downward variations and consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% 4 stars, the next 35% 3 stars, the next 22.5% 2 stars, and the bottom 10% 1 star. Each share class is counted as a fraction of one fund within this scale and rated separately. Morningstar Rating™ is for the retail share class only; other classes may have different performance characteristics.

Investors should note that the fund's short-term performance is highly unusual and unlikely to be sustained.
Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. Share price, principal value, and return will vary and you may have a gain or loss when you sell your shares.
The Equity Index 500 Fund charges a 0.5% redemption fee on shares held 90 days or less. The performance information shown does not reflect the deduction of the redemption fee; if it did, the performance would be lower.
2 Average annual total return figures include changes in principal value, reinvested dividends, and capital gain distributions. For funds less than one year old, the Since Inception return figure is not annualized and represents an aggregate total return.
