The SEC is adopting amendments to certain rules that govern money market funds under the Investment Company Act of 1940. The amendments will tighten the risk-limiting conditions of Rule 2a-7 by, among other things, requiring funds to maintain a portion of their portfolios in instruments that can be readily converted to cash, reducing the maximum weighted average maturity of portfolio holdings, and improving the quality of portfolio securities; requiring money market funds to report their portfolio holdings monthly to the Commission; and permitting a money market fund that has "broken the buck" (i.e., re-priced its securities below $1.00 per share), or is at imminent risk of breaking the buck, to suspend redemptions to allow for the orderly liquidation of fund assets. The amendments are designed to make money market funds more resilient to certain short-term market risks, and to provide greater protections for investors in a money market fund that is unable to maintain a stable net asset value per share. 75 FR 10059.
