means of paying brokerage firms for their services through commission revenue, rather than through direct payments, known as hard-dollar fees. For example, a mutual fund may offer to pay for the research of a brokerage firm by executing trades generated by that research through that brokerage firm. The broker might agree to this arrangement if the fund manager promises to spend at least $100,000 in commissions with the broker that year. Otherwise, the fund would have to pay a hard-dollar fee of $50,000 for the research. Following the mutual fund scandals of the early 2000s, the Investment Company Institute came out in favor of limiting soft dollars to proprietary research, and a number of large funds followed by curtailing soft money arrangements or eliminating them entirely.Compare with hard dollars.
