Final answer:
A diversified fund is required to have less than 5% of assets in any one issuer.
Step-by-step explanation:
A diversified fund is a type of mutual fund that spreads investments across various securities to decrease risk. The requirement for a diversified fund is that less than 5% of assets can be in any one issuer. This means that the fund cannot have a large portion of its assets invested in a single company. By diversifying the investments, the fund is able to mitigate the risk associated with individual stocks or bonds.
