Question

explain why the offer price is used to calculate the investment in a load mutual fund instead of the net asset value.

Explanation:

1. Load mutual funds charge a sales load (a commission paid to brokers or financial advisors for selling the fund) when an investor buys shares.
2. The NAV is the per-share value of the fund's total assets minus liabilities, calculated daily.
3. The offer price (also called the public offering price) is defined as $\text{Offer Price} = \text{NAV} + \text{Sales Load}$.
4. When purchasing a load mutual fund, the investor must pay this combined price to cover both the actual value of the fund shares and the associated sales commission, so the offer price is the correct basis for calculating the total investment cost.

Answer:

The offer price is used because it includes the sales load (commission) for load mutual funds, while the net asset value (NAV) only reflects the per-share value of the fund's underlying assets.
