Investment Objective

The fund seeks long-term growth of capital.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management fees	.80
Other expenses	.22
Total annual fund operating expenses	1.02

Example

The Example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$104	$325	$563	$1,248

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 154.49% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of small-cap U.S. companies. The fund currently considers small-cap companies to be those with total market capitalizations, at the time of purchase, that are equal to or less than the total market capitalization of the largest company included in Russell 2000^® Growth Index as of the Index's most recent reconstitution date. The fund's portfolio managers employ a growth-oriented investment style in managing the fund's portfolio, which means the portfolio managers seek to identify those

small-cap companies which are experiencing or are expected to experience rapid earnings or revenue growth. The portfolio managers focus on high quality companies and individual stock selection, instead of trying to predict which industries or sectors will perform best and select stocks by:

·Using fundamental research to identify and follow companies considered to have attractive characteristics, such as strong business and competitive positions, solid cash flows and balance sheets, high quality management and high sustainable growth; and

·Investing in a company when the portfolio managers' research indicates that the company will experience accelerating revenues and expanding operating margins, which may lead to rising estimate trends and favorable earnings surprises.

The fund's investment strategy may lead it to emphasize certain sectors, such as technology, health care, business services and communications.

The fund does not have any limitations regarding portfolio turnover. The fund may engage in short-term trading to try to achieve its objective and may have portfolio turnover rates significantly in excess of 100%. A portfolio turnover of 100% is equivalent to the fund buying and selling all of the securities in its portfolios once during the course of a year.

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money.

·Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general weakness in the stock market or because of factors that affect the company or its particular industry.

·Small and midsize company risk. Small and midsize companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies. The shares of smaller companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the fund's ability to sell these securities.

·Growth stock risk. Investors often expect growth companies to increase their earnings at a certain rate. If these expectations are not met, investors can punish the stocks inordinately, even if earnings do increase. In addition, growth stocks may lack the dividend yield that may cushion stock prices in market downturns.

·Market sector risk. The fund may significantly overweight or underweight certain companies, industries or market sectors, which may cause the fund's performance to be more or less sensitive to developments affecting those companies, industries or sectors.

·Liquidity risk. When there is little or no active trading market for a security, the fund may not be able to sell the security in a timely manner at its perceived value, which could cause the fund's share price to fall.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares through a broker-dealer or other financial intermediary (such as a bank), the fund and its related companies may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
