The decision to make the reduction permanent comes on the heels of a barb by Jack Brennan,
"Fee waivers are like a cents-off coupon," Brennan wrote in a shareholder notice. "The couponing lasts for as long or as short a period as the marketing folk think it's working."
Fidelity Personal Investments President Jeff Carney issued a statement saying that when Fidelity first lowered the fees, its intention all along was to make it a "long-term initiative."
"Fidelity is firmly committed, in no uncertain terms, to providing investors with high-quality index funds that are not only among the lowest-cost in the market," he continued, "but also contractually bound to stay that way."
Since it lowered the fees on the five index funds, they have attracted an additional $2 billion in net new assets, according to Fidelity.
