Fees and Expenses of the Fund

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

(expenses that you pay each year as a percentage
of the value of your investment)

	Share class
	AMR
Management fees		0.46	%
Distribution and/or service (12b-1) fees		0.00	%
Other expenses		0.13	%
Acquired Fund Fees and Expenses		0.01	%

Example

This 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:

Share class	1 year		3 years		5 years		10 years
AMR	$	61	$	192	$	335	$	750

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 rate 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 61% of the average value of its portfolio.

Principal Investment Strategies

Ordinarily, at least 80% of the Fund’s net assets (plus the amount of any borrowings for investment purposes) are invested in equity securities of small market capitalization U.S. companies. These companies generally have market capitalizations of $3 billion or less at the time of investment. The Fund’s investments may include common stocks, preferred stocks, securities convertible into common stocks, U.S. dollar-denominated American Depositary Receipts, and U.S. dollar-denominated foreign stocks traded on U.S. exchanges (collectively, “stocks”).

The Manager allocates the assets of the Fund among different sub-advisors. The Manager believes that this strategy will help the Fund outperform other investment styles over the longer term while minimizing volatility and downside risk.. The Fund’s assets are currently allocated among five investment sub-advisors.

The sub-advisors select stocks that, in their opinion, have most or all of the following characteristics (relative to the Russell 2000^® Index):

►	above-average earnings growth potential,
►	below-average price to earnings ratio, and
►	below-average price to book value ratio.

Each of the sub-advisors determines the earnings growth prospects of companies based upon a combination of internal and external research using fundamental analysis and considering changing economic trends. The decision to sell a stock is typically based on the belief that the company is no longer considered undervalued or shows deteriorating fundamentals, or that better investment opportunities exist in other stocks.

The Fund may lend its securities to broker-dealers and other institutions to earn additional income.

Principal Risks

Market Risk

Since this Fund invests most of its assets in stocks, it is subject to stock market risk. Market risk involves the possibility that the value of the Fund’s investments in stocks will decline due to drops in the stock market. In general, the value of the Fund will move in the same direction as the overall stock market, which will vary from day to day in response to the activities of individual

companies, as well as general market, regulatory, political and economic conditions.

Small Capitalization Companies Risk

Investing in the securities of small capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies, since smaller companies may have limited operating history, product lines, and financial resources, the securities of these companies may lack sufficient market liquidity and they can be particularly sensitive to expected changes in interest rates, borrowing costs and earnings.

Value Stocks Risk

Value stocks are subject to the risk that their intrinsic value may never be realized by the market or that their prices may go down. While the Fund’s investments in value stocks may limit its downside risk over time, the Fund may produce more modest gains than riskier stock funds as a trade-off for this potentially lower risk.

Foreign Investing Risk

Investing in the securities of foreign companies carries potential risks not associated with domestic investments. Such risks include, but are not limited to: (1) political and financial instability, (2) less liquidity and greater volatility, (3) lack of uniform accounting, auditing and financial reporting standards, and (4) increased price volatility.

Securities Selection Risk

Securities selected by a sub-advisor for the Fund may not perform to expectations. This could result in the Fund’s underperformance compared to other funds with similar investment objectives.

Securities Lending Risk

To the extent the Fund lends its securities, it may be subject to the following risk. Borrowers of the Fund’s securities typically provide collateral in the form of cash that is reinvested in securities. The securities in which the collateral is invested may not perform sufficiently to cover the return collateral payments owed to borrowers. In addition, delays may occur in the recovery of securities from borrowers, which could interfere with the Fund’s ability to vote proxies or to settle transactions.

Investment Risk

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Market Events

Turbulence in financial markets and reduced liquidity in credit and fixed-income markets may negatively affect many issuers worldwide which may have an adverse effect on the Fund.
