Securities issued by medium sized companies may be thinly traded and may be more difficult to sell during market downturns. Companies propelled by innovation, including technology advances and new business models, may present the risk of rapid change and product obsolescence, and their success may be difficult to predict for the long term.  Even though the Fund is diversified, it may establish significant positions where the Adviser has the greatest conviction. This could increase volatility of the Fund’s returns.

Performance data quoted represents past performance. Past performance is no guarantee of future results. The investment return and principal value of an investment will fluctuate; an investor's shares, when redeemed, may be worth more or less than their original cost. The Adviser has reimbursed certain Fund expenses and the Fund's transfer agency expenses may be reduced by expense offsets from an unaffiliated transfer agent, without which performance would have been lower. Current performance may be lower or higher than the performance data quoted above. For performance information current to the most recent month end, click here.

The Fund may not achieve its objectives.

Performance for the Institutional Shares prior to 5/29/2009 is based on the performance of the Retail Shares, which have a distribution fee. The Institutional Shares do not have a distribution fee. If the annual returns prior to 5/29/2009 did not reflect this fee, the returns would be higher.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) © 2014 Morningstar, Inc.

Definitions (provided by BAMCO, Inc.): The indexes are unmanaged. The Russell Midcap™ Growth Index measures the performance of medium-sized U.S. companies that are classified as growth and the S&P 500 Index of 500 widely held large-cap U.S. companies.  The Russell Midcap Growth Index, the S&P 500 Index and the Fund are with dividends, which positively impact the performance results.  The Morningstar Mid-Cap Growth Average is not weighted and represents the straight average of annualized returns of each of the funds in the Mid-Cap Growth category. The Fund's Retail Shares have been included in the category since inception and the Fund's Institutional Shares since 5/29/09. © 2014 Morningstar, Inc.  All Rights Reserved.  The Morningstar information contained herein: (1) is proprietary to Morningstar and/or its content providers; (2) may not be copied or distributed; and (3) is not warranted to be accurate, complete or timely.  Neither Morningstar nor its content providers are responsible for any damages or losses arising from any use of this information. 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 (Russell Midcap Growth Index) is 1.00 by definition. R-Squared: measures how closely a fund’s performance correlates to the performance of the benchmark index (Russell Midcap Growth 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 (Russell Midcap Growth Index). 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 (Russell Midcap Growth 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 (Russell Midcap Growth Index) are greater than zero. Downside Capture: explains how well a fund performs in time periods where the benchmark’s returns (Russell Midcap Growth Index) are less than zero.
