There is no clear-cut answer as to which share class is the best. All
three have their advantages and disadvantages. For larger amounts
of money, Class A shares would probably be the best due to the
reduction in the sales charge and since there are no back-end fees.
If your money is within an IRA, perhaps Class B shares would be
the better option. But if you wanted to invest your money and
thought that you may need it within a few years, Class C shares
may be the way to go. The share class that you invest in is really
determined by your time frame. You may find that a mixture of
share classes is preferable.
