Much of Desilu Productions' early success can be traced to Arnaz's unusual business style in his role as producer of "I Love Lucy". For example, lacking formal business training, he knew nothing of amortization and often included all the costs incurred by the production into the first episode of a season rather than spreading them across the projected number of episodes in the year. As a result, by the end of the season, episodes were nearly entirely paid for, at preposterously low figures.
