(3) The amount or value of the property;

(4) The last address of the apparent owner, if known to the holder;

(5) Working papers documenting items considered for reporting that were not ultimately determined to represent unclaimed property, to allow examination to determine whether the holder has complied with this chapter;

(6) If the holder sells, issues, or provides to others for sale or issue in this state traveler’s checks, money orders, or similar instruments, other than third-party bank checks, on which the holder is directly liable, a record of the instruments while they remain outstanding indicating the state and date of issue;

(7) Deductions for service charges incurred after the report date;

(8) Interest accruing on reportable amounts or contracts providing for the cessation of such interest; and
