Fund Summary -

i23004gd New York AMT-Free Municipal Cash Management

Investment Objective

The fund seeks as high a level of current income exempt from federal, New York state and New York city personal income taxes as is consistent with the preservation of capital and the maintenance of liquidity.

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) |
| Institutional Shares
Management fees | .20
Other expenses (including shareholder services fees) | .14
Total annual fund operating expenses | .34

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
Institutional Shares | $35 | $109 | $191 | $431

Principal Investment Strategy

As a money market fund, the fund is subject to the maturity, quality, liquidity and diversification requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended, which are designed to help money market funds maintain a stable share price of $1.00. To pursue its goal, the fund normally invests substantially all of its net assets in short-term, high quality municipal obligations that provide income exempt from federal, New York state and New York city income taxes. The fund does not invest in municipal obligations that pay interest subject to the federal alternative minimum tax. The fund also may invest in high quality, short-term structured notes, which are derivative instruments whose value is tied to underlying municipal obligations.

Although the fund seeks to provide income exempt from federal, New York state and New York city personal income taxes, the fund may invest temporarily in high quality, taxable money market instruments and/or municipal obligations that pay income exempt only from federal income tax, including when the portfolio manager believes that acceptable New York municipal obligations are unavailable for investment.

Principal Risks

An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.

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. Additionally, while the fund has maintained a constant share price since inception, and will continue to try to do so, neither The i23004gd Corporation nor its affiliates are required to make a capital infusion, enter into a capital support agreement or take other actions to prevent the fund's share price from falling below $1.00. The following are the principal risks that could reduce the fund's income level and/or share price:

· 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.

· Credit risk. Failure of an issuer to make timely interest or principal payments, or a decline or perception of a decline in the credit quality of a security, can cause the security's price to fall, potentially lowering the fund's share price. Although the fund invests only in high quality debt securities, any of the fund's holdings could have its credit rating downgraded or could default. The credit quality of the securities held by the fund can change rapidly in certain market environments, and the default of a single holding could have the potential to cause significant deterioration of the fund's net asset value.

· 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 at or near their perceived value. In such a market, the value of such securities may fall dramatically, potentially lowering the fund's share price, even during periods of declining interest rates. Also, during such periods, redemptions by a few large investors in the fund may have a significant adverse effect on the fund's net asset value and remaining fund shareholders.

· Municipal securities risk . The amount of public information available about municipal securities is generally less than that for corporate equities or bonds. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the fund's investments in municipal securities. Other factors include the general conditions of the municipal securities market, the size of the particular offering, the maturity of the obligation and the rating of the issue. Changes in economic, business or political conditions relating to a particular municipal project, municipality, or state in which the fund invests may have an impact on the fund's share price.

· Tax risk. To be tax-exempt, municipal obligations generally must meet certain regulatory requirements. If any such municipal obligation fails to meet these regulatory requirements, the interest received by the fund from its investment in such obligations and distributed to fund shareholders will be taxable.

· Structured notes risk. Structured notes, a type of derivative instrument, can be volatile, and the possibility of default by the financial institution or counterparty may be greater for these instruments than for other types of money market instruments. Structured notes typically are purchased in privately negotiated transactions from financial institutions and, thus, an active trading market for such instruments may not exist.

· State -specific risk. The fund is subject to the risk that New York's economy, and the revenues underlying its municipal obligations, may decline. Investing primarily in a single state makes the fund more sensitive to risks specific to the state and may magnify other risks.

· Non -diversification risk. The fund is non-diversified, which means that a relatively high percentage of the fund's assets may be invested in a limited number of issuers. Therefore, the fund's performance may be more vulnerable to changes in the market value of a single issuer or a group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

Performance

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Institutional shares from year to year. The table shows the average annual total returns of the fund's Institutional shares over time. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future.

Portfolio Management

The fund's investment adviser is The i23004gd Corporation.

Purchase and Sale of Fund Shares

The fund is designed for institutional investors. In general, the fund's minimum initial investment is $10,000,000. Certain types of accounts are eligible for lower minimum investments. You may sell (redeem) your shares on any business day by wire, telephone or compatible computer facility. Your shares will be sold at the next net asset value calculated after your order is received in proper form.

Tax Information

The fund anticipates that virtually all dividends paid by the fund will be exempt from federal, New York state and New York city personal income taxes. However, for federal tax purposes, certain distributions, such as distributions of short-term capital gains, are taxable as ordinary income, while long-term capital gains are taxable as capital gains.

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.
