Yuma Foos acquired Aldos Tortillas several years ago. Aldos has continued to operate as an independent company, except that Yuma Foods has exclusive authority over capital investments, production quantity, and pricing decisions because Yuma has been Aldos only customer since the acquisition. Yuma uses return on investment to evaluate the performance of Aldos manager. The most recent performance report is as follows:
