" The Custodian. When a mutual fund is established, a separate organization, most often a trust company, is appointed as the fund’s custodian. The custodian receives and holds the fund’s money obtained from all sources – investors buying the fund’s units or shares, income earned by the fund’s investment portfolio, proceeds from the sale of the fund’s investments, holds all the fund’s assets and distributes the fund’s money to pay the fund’s expenses.
