Fund redemption generally has two requirements, sometimes only one.

The minimum share of a single redemption, for example, the redemption shall not be less than 100 shares.

The minimum requirements for the remaining fund shares, such as after redemption, shall not be less than 100.

But there is an exception, that is, if the fund share itself is small and below the redemption limit, it can also be redeemed, that is, all redemptions will do.
