First American Funds, which manages almost $50 billion in money funds (all AAA rated), comments on the SEC's proposed "Broker-Dealer Responsibility Rules". The adviser urges the Commission to allow AAA rated money funds as "qualifed securities" under Rule 15c3-3. Currently, the proposed rules only allow Government funds to be used as brokerage collateral, but many are urging the SEC to include "prime" funds.
