Risks: In addition to the general stock market risk that securities may fluctuate in value, investments in developing countries may have increased risks due to a greater possibility of: settlement delays; currency and capital controls; interest rate sensitivity; corruption and crime; exchange rate volatility; and inflation or deflation. The Fund invests in companies of all sizes, including small and medium sized companies whose securities may be thinly traded and more difficult to sell during market downturns.

The Fund may not achieve its objectives.

Definitions (provided by BAMCO, Inc.): The MSCI EM (Emerging Markets) Index Net USD is designed to measure equity market performance of large and mid-cap securities across 23 Emerging Markets countries. The MSCI EM (Emerging Markets) IMI Growth Index Net USD is a free float-adjusted market capitalization index designed to measure equity market performance of large, mid and small-cap securities exhibiting overall growth characteristics across 23 Emerging Markets countries. The indexes and the Fund include reinvestment of dividends, net of withholding taxes, which positively impact the performance results. The indexes are unmanaged. The index performance is not Fund performance; one cannot invest directly into an index.

Definitions (provided by BAMCO, Inc.): Standard Deviation: measures the degree to which a fund’s performance has varied from its average performance over a particular time period. The greater the standard deviation, the greater a fund’s volatility (risk). Sharpe Ratio: is a risk-adjusted performance statistic that measures reward per unit of risk. The higher the Sharpe ratio, the better a fund’s risk adjusted performance. Alpha: measures the difference between a fund’s actual returns and its expected performance, given its level of risk as measured by beta. Beta: measures a fund’s sensitivity to market movements. The beta of the market is 1.00 by definition. R-Squared: measures how closely a fund’s performance correlates to the performance of the benchmark index, and thus is a measurement of what portion of its performance can be explained by the performance of the index. Values for R-Squared range from 0 to 100, where 0 indicates no correlation and 100 indicates perfect correlation. Tracking Error: measures how closely a fund’s return follows the benchmark index returns. It is calculated as the annualized standard deviation of the difference between the fund and the index returns. Information Ratio: measures the excess return of a fund divided by the amount of risk the fund takes relative to the benchmark index. The higher the information ratio, the higher the excess return expected of the fund, given the amount of risk involved. Upside Capture: explains how well a fund performs in time periods where the benchmark’s returns are greater than zero. Downside Capture: explains how well a fund performs in time periods where the benchmark’s returns are less than zero

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.
