The smallest investment amount accepted for establishing an individual retirement account. If a dash appears in this field, 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 a fund's individual retirement account. IRA investors may receive distributions on a tax-free basis, but they must be reinvested in the IRA or be subject to significant IRS penalties. Frequently, the minimum initial IRA purchase amount is less than the fund's normal minimum initial investment amount. This allows investors access to funds they may not otherwise enjoy.
