Total Annual Fund Operating Expenses for the Fund's R class have been restated to reflect an anticipated decrease in Other Expenses. Effective April 1, 2013, the Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any) paid by the Fund's R, IS and SS classes (after the voluntary waivers and/or reimbursements) will not exceed 1.22%, 0.58% and 0.81% (the “Fee Limit”), respectively, up to but not including the later of (the “Termination Date”): (a) April 1, 2014; or (b) the date of the Fund's next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Fund's Board of Trustees.

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 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 operating expenses are as shown in the table above and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

Share Class	1 Year	3 Years	5 Years	10 Years
R	$121	$378	$654	$1,443
IS	$ 87	$271	$471	$1,049
SS	$ 92	$287	$498	$1,108

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 187% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund's overall strategy is generally to invest in a portfolio consisting of U.S. Treasury securities and U.S. government agency securities with maturities of not less than two years and not more than five years. The Fund may also use derivative contracts and/or hybrid instruments to implement elements of it strategies. The Fund buys and sells portfolio securities based primarily on its market outlook and analysis of how securities may perform under different market conditions. The Fund evaluates its investment strategy by comparing the performance and composition of the Fund's portfolio to the performance and composition of Bank of America Merrill Lynch 3-5 Year Treasury Index, an index composed of U.S. Treasury notes and bonds with maturities greater than or equal to three years and less than five years.

U.S. government securities also may be offered on a delayed delivery basis. The Fund will enter into delayed delivery transactions, including when-issued transactions, in order to participate in these offerings or trade these securities. The Fund may also seek to increase its income by lending its portfolio securities.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (Freddie Mac), the Federal National Mortgage Association (Fannie Mae), and the Federal Home Loan Bank System.

These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (Ginnie Mae). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

The Fund may also purchase bonds from the U.S. government backed by the Federal Deposit Insurance Corporation (FDIC).

During extreme market conditions such as a zero yield environment, the Fund may invest in government mortgage-backed securities as a temporary investment. The government mortgage-backed securities in which the Fund may invest are government mortgage-backed securities such as those issued by Ginnie Mae, Fannie Mae and Freddie Mac.

Because the Fund refers to U.S. government securities in its name, it will notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to invest, under normal circumstances, less than 80% of its assets (plus any borrowings for investment purposes) in U.S. government investments.

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

■	Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise, which may result in a decrease in the value of Fund Shares.
■	Liquidity Risk. Trading opportunities are more limited for fixed-income securities that have not received any credit ratings, have received ratings below investment grade or are not widely held. These features may make it more difficult to sell or buy a security at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash or give up an investment opportunity, any of which could have a negative effect on the Fund's performance. Infrequent trading of securities may also lead to an increase in their price volatility. Liquidity risk also refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract when it wants to. If this happens, the Fund will be required to continue to hold the security or keep the position open, and the Fund could incur losses. Over-the-counter (OTC) derivative contracts generally carry greater liquidity risk than exchange-traded contracts.
■	Leverage Risk. Leverage risk is created when an investment, which includes, for example, an investment in a derivative contract, exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund's risk of loss and potential for gain. Investments can have these same results if their returns are based on a multiple of a specified index, security or other benchmark.

■	Risk of Investing in Derivative Contracts and Hybrid Instruments. Derivative contracts and hybrid instruments involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts and instruments include valuation and tax issues, increased potential for losses and/or costs to the Fund and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts and hybrid instruments may also involve other risks described in this Prospectus or the Fund's Statement of Additional Information (SAI), such as interest rate, credit, liquidity and leverage risks.
■	Risk of Investing in Inflation-Protected Securities. The value of inflation-protected securities is subject to the effects of changes in market interest rates caused by factors other than inflation (“real interest rates”). If interest rates rise due to reasons other than inflation, the Fund's investment in these securities may not be protected to the extent that the increase is not reflected in the security's inflation measure. Generally, when real interest rates rise, the value of inflation-protected securities will fall and the Fund's value may decline as a result of this exposure to these securities. The greatest risk occurs when interest rates rise and inflation declines.
■	Prepayment Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities.
■	Credit Risk. It is possible that interest or principal on securities will not be paid when due. Such non-payment or default may reduce the value of the Fund's portfolio holdings, its share price and its performance.
■	Mortgage-Backed Securities Risk. Mortgage-backed securities (MBS) have unique risks. A rise in interest rates may cause the value of MBS held by the Fund to decline. MBS are subject to the risk that payments made on a security will not be made when due. Certain MBS issued by U.S. government-sponsored enterprises are not backed by the full faith and credit of the U.S. government.
■	Technology Risk. Proprietary and third party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance: Bar Chart and Table

Risk/Return Bar Chart

The bar chart and performance table below reflect historical performance data for the Fund and are intended to help you analyze the Fund's investment risks in light of its historical returns. The bar chart shows the variability of the Fund's IS class total returns on a calendar year-by-year basis. The Average Annual Total Return Table shows returns for each class averaged over the stated periods, and includes comparative performance information. The Fund's performance will fluctuate, and past performance (before and after taxes) is not necessarily an indication of future results.

Within the periods shown in the bar chart, the Fund's IS class highest quarterly return was 6.20% (quarter ended December 31, 2008). Its lowest quarterly return was (2.44)% (quarter ended June 30, 2004).

Average Annual Total Return Table

In addition to Return Before Taxes, Return After Taxes is shown for the Fund's IS class to illustrate the effect of federal taxes on Fund returns. After-tax returns are shown only for IS class, and after-tax returns for R and SS classes will differ from those shown for IS class. Actual after-tax returns depend on each investor's personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical federal income and capital gains tax rates. These after-tax returns do not reflect the effect of any applicable state and local taxes. After-tax returns are not relevant to investors holding Shares through a 401(k) plan, an Individual Retirement Account or other tax-advantaged investment plan.
