Baron WealthBuilder Fund (BWBFX)

Investors should consider the investment objectives, risks, and charges and expenses of the investment carefully before investing. The prospectus and summary prospectuses contain this and other information about the Funds. You may obtain them from the Funds’ distributor, Baron Capital, Inc., by calling 1-800-99BARON or visiting www.BaronFunds.com. Please read them carefully before investing.

Risks: The Fund is a non-diversified fund because it invests, at any given time, in the securities of a select number of Baron mutual funds (the “Underlying Funds”), representing specific investment strategies. The Fund can invest in funds holding U.S. and international stocks; small-cap, small to mid-cap, large-cap, all-cap stocks; and specialty stocks. Each of the Underlying Funds has its own investment risks, and those risks can affect the value of the Fund’s investments and therefore the value of the Fund’s shares. To the extent that the Fund invests more of its assets in one Underlying Fund than in another, it will have greater exposure to the risks of that Underlying Fund. For further information regarding the investment risks of the Underlying Funds, please refer to the Underlying Funds’ prospectus.

The Fund may not achieve its objectives.

Definitions (provided by Baron Capital, Inc.): EPS Growth Rate (3-5 Year): indicates the long-term forecasted EPS growth of the companies in the portfolio, calculated using the weighted average of the available 3-to-5 year forecasted growth rates for each of the stocks in the portfolio provided by Factset Estimates. The EPS Growth rate does not forecast the Fund’s performance. Price/ Earnings Ratio (trailing 12-months): is a valuation ratio of a company’s current share price compared to its actual earnings per share over the last twelve months. Price/Book Ratio: is a ratio used to compare a company’s stock price to its tangible assets, and it is calculated by dividing the current closing price of the stock by the latest quarter’s book value per share. Price/Sales Ratio: is a valuation ratio of a stock’s price relative to its past performance. It represents the amount an investor is willing to pay for a dollar generated from a particular company’s operations. Price/Sales is calculated by dividing a stock’s current price by its revenue per share for the last 12 months. Weighted Harmonic Average: is a calculation that reduces the impact of extreme observation on the aggregate calculation by weighting them based on their size in the fund. Active Share is a term used to describe the share of a portfolio’s holdings that differ from that portfolio’s benchmark index. It is calculated by comparing the weight of each holding in the Fund to that holding’s weight in the benchmark. Positions with either a positive or negative weighting versus the benchmark have Active Share. An Active Share of 100% implies zero overlap with the benchmark. Active Share was introduced in 2006 in a study by Yale academics, M. Cremers and A. Petajisto, as a measure of active portfolio management.

One year turnover information to the most recent quarter and average market cap (unweighted) is available upon request.
