Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table.

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 operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was
0
% of the average value of its portfolio.

Principal Investment Strategies
Normally investing at least 80% of assets in securities included in the Bloomberg U.S. 3-6 Month Treasury Bill Index.
The index is a market capitalization-weighted index of investment-grade, fixed-rate public obligations of the U.S. Treasury with maturities from 3 up to (but not including) 6 months, excluding zero coupon strips.
Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.
Using statistical sampling techniques based on duration, maturity, interest rate sensitivity, security structure, and credit quality to attempt to replicate the returns of the Bloomberg U.S. 3-6 Month Treasury Bill Index using a smaller number of securities.
Interest Rate Changes.
Interest rate increases can cause the price of a debt security to decrease.
Issuer-Specific Changes.
The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.
A decline in the credit quality of an issuer or a provider of credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) for a security can cause the price of a security to decrease.
U.S. Treasury Obligations.
U.S. Treasury obligations are high-quality securities issued or guaranteed by the U.S. Treasury providing minimal risk of loss of principal if held to maturity. Fluctuations in interest rates may cause the market value of such securities to vary.
Correlation to Index.
The performance of the fund and its underlying index may vary somewhat due to factors such as fees and expenses of the fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on the fund and its shareholders.
Passive Management Risk.
The fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the fund's index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the fund's performance could be lower than actively managed funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers.
The fund will be concentrated to approximately the same extent that the fund's index concentrates in the securities of issuers in a particular industry or group of industries.
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
.
You could lose money by investing in the fund.

Principal Investment Strategies
Normally investing at least 99.5% of total assets in cash, U.S. Government securities and/or repurchase agreements that are collateralized fully (i.e., collateralized by cash or government securities).
Investing in U.S. Government securities issued by entities that are chartered or sponsored by Congress but whose securities are neither issued nor guaranteed by the U.S. Treasury.
Investing in compliance with industry-standard regulatory requirements for money market funds for the quality, maturity, liquidity, and diversification of investments.
In addition, the fund normally invests at least 80% of its assets in U.S. Government securities and repurchase agreements for those securities.
U.S. Government securities are high-quality securities issued or guaranteed by the U.S. Treasury or by an agency or instrumentality of the U.S. Government. U.S. Government securities may be backed by the full faith and credit of the U.S. Treasury, the right to borrow from the U.S. Treasury, or the agency or instrumentality issuing or guaranteeing the security. Certain issuers of U.S. Government securities, including Fannie Mae, Freddie Mac, and the Federal Home Loan Banks, are sponsored or chartered by Congress but their securities are neither issued nor guaranteed by the U.S. Treasury. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security.
A repurchase agreement is an agreement to buy a security at one price and a simultaneous agreement to sell it back at an agreed-upon price. A repurchase agreement entered into by the fund may be collateralized by U.S. Government securities or cash.
Interest Rate Changes.
Interest rate increases can cause the price of a money market security to decrease.
Income Risk.
A low or negative interest rate environment can adversely affect the fund's yield.
Issuer-Specific Changes.
A decline in the credit quality of an issuer or a provider of credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) for a security can cause the price of a money market security to decrease.
U.S. Government Obligations Risk.
Certain securities in which the fund may invest, including securities issued by certain U.S. Government agencies and U.S. Government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States.
You could lose money by investing in the fund

Use of Blockchain
The fund's transfer agent maintains the official record of share ownership of the OnChain class in book-entry form. Ownership of the OnChain class will also be recorded - or digitized - on a public blockchain. Although the secondary recording of the OnChain class on a blockchain will not represent the official record of ownership, the transfer agent will reconcile the secondary blockchain transactions with the official records of the OnChain class on at least a daily basis during business days under normal conditions. Reconciliation involves maintaining a matching book-entry record and blockchain record of the total number of shares in circulation and the ownership of the shares at any given time.
A blockchain is an open, distributed ledger that digitally records transactions in a verifiable and immutable (i.e., permanent) way using cryptography. A distributed ledger is a database in which data is stored in a decentralized manner. Cryptography is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. A blockchain stores transaction data in "blocks" that are linked together to form a "chain", hence the name blockchain.
The secondary recording of OnChain class shares on a blockchain will not affect the fund's investments or its investment strategies. The fund will invest, consistent with Rule 2a-7 under the Investment Company Act of 1940 (1940 Act), at least 99.5% of total assets in cash and U.S. Treasury securities. The fund will not invest in any crypto assets.
For more information regarding the use of blockchain technology for the OnChain class, see "Use of Blockchain" in the Fund Basics section of this prospectus. More detailed information about blockchain technology and the public blockchain network(s) used by the fund's transfer agent, including the regulatory, operational and technological risks associated with distributed ledger technology, as well as detailed information about the fund and its policies and risks, can be found in the fund's Statement of Additional Information (SAI).
