What are Class C Share Mutual Funds?

Answer:
Mutual fund "classes" affect how investors

purchase and maintain mutual fund investments.

Some mutual fund classes are bought with up-front payment, while others might be bought with a delayed payment schedule. Likewise, some mutual fund classes might apply a particular fee structure for annual "maintenance" of the funds that other classes do not apply in the same way or at the same rates.

Class C share mutual funds are financial investment entities which "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".
All within quotes is according to the Securities and Exchange Commission website. So, what does that all mean?

Generally speaking, it means that class C mutual funds typically end up costing investors more in fees and payments than class B or class A mutual funds would cost.
