Money Management Executive writes "SEC Tightens Money Fund Rules, saying, "The Securities and Exchange Commission last Wednesday adopted several amendments to Rule 2a-7 governing money market funds that aim to reduce risks by increasing credit quality, improving liquidity, shortening maturity limits and requiring the disclosure of a fund's 'shadow' net asset value. The Commission fell short of requiring a floating NAV, but said it may still consider such a move in the future, as well as eliminating the disclosure delay on holdings and the use of credit ratings agencies."
