***Expense Example***

This example is intended to help you compare the cost of investing in shares of 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, that you pay the maximum contingent deferred sales charge (you had exchanged into the Fund when you were still subject to a deferred sales charge (for Class A and C shares only)), 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** |
| Class A Shares | $8 | $26 | $45 | $102 |
| Class C Shares | $108 | $26 | $45 | $102 |
| Class I Shares | $8 | $26 | $45 | $102 |

---

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

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **1 Year** | **3 Years** | **5 Years** | **10 Years** |
| Class A Shares | $8 | $26 | $45 | $102 |
| Class C Shares | $8 | $26 | $45 | $102 |
| Class I Shares | $8 | $26 | $45 | $102 |

***Principal Investment Strategies***

Under normal market conditions, the Fund invests at least 99.5% of its total assets in cash, U.S. Treasury obligations, including U.S. Treasury bills, U.S. Treasury notes, U.S. Treasury bonds, and U.S. Treasury strips ("U.S. Treasury Obligations"), and repurchase agreements that are collateralized fully by such obligations or cash and at least 80% of its net assets in U.S. Treasury Obligations and repurchase agreements that are collateralized fully by such obligations. Currently, the Fund invests exclusively in such U.S. Treasury Obligations.

The Fund is a money market fund managed to meet the requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended (the "1940 Act"). Within these requirements, the Fund will seek to maintain a net asset value of $1.00 per share. Other requirements pertain to the maturity, liquidity, and credit quality of the securities in which the Fund may invest. The Fund will only invest in securities which have, or are deemed to have, a remaining maturity of 397 days or less. In addition, the dollar-weighted average maturity for all securities contained in the Fund is required to be sixty days or less. The Fund will also limit its dollar-weighted average life (portfolio maturity measured without reference to any maturity shortening provisions of adjustable rate securities by reference to their interest rate reset date) to 120 days.

The Fund qualifies as a "government money market fund," as such term is defined in or interpreted under Rule 2a-7 under the 1940 Act. "Government money market funds" are required to invest at least 99.5% of their total assets in (i) cash, (ii) securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities and/or (iii) repurchase agreements that are collateralized fully, and are exempt from requirements that permit money market funds to impose liquidity fees. While the Fund's Board of Trustees (the "Board") may elect to subject the Fund to liquidity fees in the future, it has not elected to do so at this time.

The Manager may consider the following factors when buying and selling securities for the Fund: (i) portfolio liquidity and (ii) redemption requests.

***Principal Risks***

***You may want to invest in the Fund if:***

● you desire a fund with lower expenses than the average U.S. Treasury money market fund

● you seek stability of principal more than growth of capital or high current income

● you seek income free from state and local taxes

● you intend to exchange into other Gabelli sponsored mutual funds

You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

The Fund's yield will fluctuate as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. The following are the principal risks that could reduce the Fund's income level and/or share per price:

● **Government Money Market Fund Risk.** The Fund is a "government money market fund," as such term is defined or interpreted under the rules governing money market funds. A "government money market fund" is a money market fund that invests 99.5 percent or more of its total assets in cash, government securities, and repurchase agreements that are collateralized fully. As a "government money market fund," the Fund can value its securities using the amortized cost method to seek to maintain a stable $1.00 share price. Changes in government regulations may adversely affect the value of a security held by the Fund. These changes may result in reduced yields for money market funds, including the Fund. The SEC or other regulators may adopt additional money market fund reforms impacting the Fund's structure, operation, or performance.

● **U.S. Treasury Securities Risk.** U.S. Treasury securities include direct obligations of the U.S. Treasury, such as Treasury bills, notes, and bonds. A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity. Such securities are subject to variations in market value due to fluctuations in interest rates and in government policies, but, if held to maturity, are expected to be paid in full (either at maturity or thereafter). However, from time to time, a high national debt level, and uncertainty regarding negotiations to increase the U.S. government's debt ceiling and periodic legislation to fund the government, could increase the risk that the U.S. government may default on its obligations and/or lead to a downgrade of the credit rating of the U.S. government. Such an event could adversely affect the value of investments in securities backed by the full faith and credit of the U.S. government and the Fund's ability to preserve the value of your investment, and lead to significant disruptions in U.S. and global markets.

● **Credit Risk.** The risk that the inability or perceived inability of the issuer to make interest and principal payments will cause the value of the securities to decrease.

● **Interest Rate Risk.** This risk refers to the decline in the prices of fixed income securities that may accompany a rise in the overall level of interest rates. A sharp and unexpected rise in interest rates could cause a money market fund's share price to drop below a dollar. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of Fund assets and could impair the Fund's ability to maintain a stable net asset value. The Fund may be subject to heightened interest rate risk as a result of changes in economic conditions, inflation and government monetary policy, such as changes in the federal funds rate. There is no way of predicting the frequency or quantum of potential interest rate changes.

● **Liquidity Risk.** When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities may fall dramatically, potentially impairing the Fund's ability to maintain a stable net asset value, even during periods of declining interest rates. Also, during such periods, redemptions by a few large investors in the Fund may impair the Fund's ability to maintain a stable net asset value.

● **Large Shareholder Risk.** Certain shareholders, including the Adviser and its affiliates, may own a substantial amount of the Fund's shares. The Fund is subject to the risk that a redemption by those shareholders of all or a large portion of their Fund shares will adversely affect the Fund's performance by requiring the Fund to sell portfolio securities, potentially at disadvantageous prices, to raise the cash needed to satisfy the redemption request. Redemptions of a large number of shares also may affect the liquidity of the Fund's portfolio, increase transaction costs or, by necessitating a sale of portfolio securities, have adverse tax consequences for Fund shareholders. Additionally, redemptions that require the Fund to sell portfolio securities may limit the Fund's ability to use capital loss carryforwards and other losses to offset future realized capital gains (if any).
