According to SEBI's new recategorization norms for the mutual fund, many mutual fund houses have merged their schemes. Many of these schemes are merged into some existing scheme. And some other existing scheme merged with another scheme to form a new scheme. As the schemes have been merged, SEBI has to disclose standardize performance of the mutual fund scheme. SEBI has asked mutual fund houses to disclose the weighted average performance of the new as well as the old product.
