Bargain Purchase Option
  
ThunderCats leases heavy equipment from Transformers, Inc. They sign a lease agreement containing a bargain purchase option clause, which allows ThunderCats to buy the equipment at a discounted price when the lease period expires.
The primary function of such a clause is to minimize the "off balance sheet" financing for the ThunderCats, which ultimately affects their level of liability and debt. All hail Lord Lion-O.
