A Share is one of the four multi-class mutual funds. This is the class that is usually characterized by a loaded fee structure.
Class A mutual fund units will commonly have a front- or rear-end load, to compensate for the sales person's commission. Not all fund companies follow this class structure; however, it is the prominent method of distinction. Typically, the class A fund has a lower management expense ratio compared to the other classes within the same family. This is due to the load that is added to the acquisition cost, or redemption.
For the other classes refer to following
A multi-class fund with three classes of shares that are sold to the general public—Class A, Class B, and Class C—and a class that is sold only to institutional investors—Class I.
Class A shares might have a front-end sales load (a type of fee that investors pay when they purchase fund shares).
Class B shares might not have any front-end sales load, but might have a contingent deferred sales load (CDSL) (a type of fee that investors pay only when they redeem fund shares, and that typically decreases to zero if the investors hold their shares long enough) and a 12b-1 fee (an annual fee paid by the fund for distribution and/or shareholder services). Class B shares also might convert automatically to a class of shares with a lower 12b-1 fee if held by investors long enough.
Class C shares might have a 12b-1 fee and a CDSL or front-end sales load, but the CDSL or sales load would be lower than Class B’s CDSL or Class A’s front-end sales load, and the Class would not convert to another class.
Class I would be sold only to institutional investors and might have different fees and expenses.
If a fund offers multiple classes, it may describe them all in a single prospectus, or it may describe them separately in separate prospectuses. The decision as to which class best suits an investor’s investment goals should be made after careful consideration of the information disclosed in the prospectus (or prospectuses). To figure out how the costs of a mutual fund add up over time and to compare the costs of different mutual funds, you should use the a mutual fund cost calculator.
Mutual fund classes are regulated primarily under the Investment Company Act of 1940 and the rules and registration forms adopted under that Act, in particular Rule 18f-3.
