The Securities and Exchange Commission ("Commission" or "SEC") is adopting amendments to the rules that govern money market mutual funds (or "money market funds") under the Investment Company Act of 1940 ("Investment Company Act" or "Act").

The SEC also is adopting amendments that will give the boards of directors of money market funds new tools to stem heavy redemptions by giving them discretion to impose a liquidity fee if a fund's weekly liquidity level falls below the required regulatory threshold, and giving them discretion to suspend redemptions temporarily, i.e., to "gate" funds, under the same circumstances.

In addition, the SEC is adopting amendments designed to make money market funds more resilient by increasing the diversification of their portfolios, enhancing their stress testing, and improving transparency by requiring money market funds to report additional information to the SEC and to investors.
