The company that manages a mutual fund is called an AMC. For all practical purposes, it is an organized form of a “money portfolio manager”. An AMC may have several mutual fund schemes with similar or varied investment objectives. The AMC hires a professional money manager, who buys and sells securities in line with the fund's stated objective.

This depends on the underlying instrument that a mutual fund invests in, based on its investment objectives. Mutual funds that invest in stock market-related instruments cannot be termed “risk-free or safe” as investment in shares are inherently risky by nature, whereas funds that invest in fixed-income instruments are relatively safe and those that invest only in government securities are the safest.

The value of all the securities in mutual fund’s portfolio is calculated daily. From this, all expenses are deducted and the resultant value divided by the number of units in the fund is the fund’s NAV or its Net Asset Value.

NAV is the total asset value (net of expenses) per unit of the fund and is calculated by the Asset Management Company (AMC) at the end of every business day. Net asset value on a particular date reflects the realisable value that the investor will get for each unit that he his holding if the scheme is liquidated on that date.

Some Asset Management Companies (AMCs) have sales charges, or loads, on their funds (entry load and/or exit load) to compensate for distribution costs. Funds that can be purchased without a sales charge are called no-load funds. Entry load is charged at the time an investor purchases the units of a scheme. The entry load percentage is added to the prevailing NAV at the time of allotment of units. Exit load is charged at the time of redeeming (or transferring an investment between schemes). The exit load percentage is deducted from the NAV at the time of redemption (or transfer between schemes). This amount goes to the Asset Management Company and not into the pool of funds of the scheme.

Offshore funds specialise in investing in foreign companies or corporations. These funds have non-residential investors and are regulated by the provisions of the foreign countries where these are registered. These funds are regulated by RBI directives.
