The smallest investment amount accepted for establishing an automatic investment plan. If this field is dashed out, the fund does not have a plan. If the minimum is zero, then $0 will appear. This figure indicates the minimum amount that may be invested in automatic investment plans, whereby funds automatically withdraw a predetermined amount from an investor's checking account on a regular basis. Frequently, the minimum AIP amount is less than the fund's normal minimum investment amount. This allows investors access to funds they may not otherwise enjoy.
