If the fund plans to sell a scheme to another fund the asset management company has to take the permission of 75 percent of unit holders or allow them to redeem without any exit load. This does not mean that the investor has nothing to worry about.
You need to find out whether the scheme is going to be managed by a different mutual fund and whether it suits your objective. Also find out the past performance of similar schemes. Note that such a change may have a bearing on the future financial performance of that fund. In case you are not comfortable with the various changes associated with the fund ship out.
