The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same and you reinvest all dividends and distributions. 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
A Shares	$	322	$	474	$	641	$	1,122
C Shares	$	257	$	486	$	839	$	1,834
I Shares	$	55	$	173	$	302	$	677

You would pay the following expenses if you did not redeem your shares:

	1 Year		3 Years		5 Years		10 Years
A Shares	$	322	$	474	$	641	$	1,122

Portfolio Turnover

The Fund pays transaction costs 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 147% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests exclusively in short-term U.S. Treasury securities (those with remaining maturities of 5 years or less) and shares of registered money market funds that invest in the foregoing. The Fund intends to maintain an average weighted maturity from 1 to 3 years.

The Fund’s subadviser, StableRiver Capital Management LLC (the “Subadviser”) manages the Fund from a total return perspective. That is, the Subadviser makes day to day investment decisions for the Fund with a view toward maximizing total return. In selecting investments for purchase and sale, the Subadviser attempts to identify U.S. Treasury securities with maturities that offer a comparably better return potential and yield than either shorter maturity or longer maturity securities for a given level of interest rate risk.

In addition, to implement its investment strategy, the Fund may buy or sell, to a limited extent, derivative instruments (such as futures, options and swaps) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk.

Principal Investment Risks

Short-term U.S. Government Debt Securities Risk: Short-term U.S. Treasury securities may underperform other segments of the fixed income market or the fixed income market as a whole.

Interest Rate Risk: Debt securities will lose value because of increases in interest rates. U.S. Government securities can exhibit price movements resulting from changes in interest rates. Interest rate risk is generally higher for investments with longer maturities or durations. Treasury inflation protected securities (“TIPS”) can exhibit price movements as a result of changing inflation expectations and seasonal inflation patterns.

Derivatives Risk: Because the Fund may invest in derivatives, it is exposed to additional volatility and potential loss. Losses on investments in certain types of derivatives may exceed the Fund’s initial investment.

A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance

The bar chart and the performance table that follow illustrate the risks and volatility of an investment in the Fund. The Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future.

This table compares the Fund’s average annual total returns for the periods indicated with those of a broad measure of market performance. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.
