When is an overdue item considered lost?

When an item ages 45 days past due, it is considered lost and the replacement cost of the material as well as an overdue fine is billed to the account. If the customer returns this material in good condition within one year of the billing date, the replacement cost of this item will be waived in favor of the overdue fine. After one year, the replacement cost will not be waived upon return regardless of condition.
