Class B Shares
Mutual fund shares that usually have a back-end load (commission) rather than a front-end load. For example, if you buy shares in a traditional load mutual fund, you usually have to pay an upfront sales commission. But with Class B shares, the commission is tacked on when you sell rather than when you buy.
Commissions on Class B shares are usually based on the length of time you hold them. For example, you might pay a 4 percent sales charge if you sell within the first year, a 3 percent charge if you sell in the second, and no charge at all if you hold on for five years or longer.
