Notwithstanding any rules of the commissioner to the contrary, if real estate owned by a bank pursuant to clauses (2) to (5) of subdivision 1 is not sold or otherwise disposed of within the maximum period established by rule by the commissioner, the bank may write off any remaining balance at a rate not less than one-fifth of that balance each subsequent calendar year.
