Designer Surfaces, Inc., supplied countertops to homeowners who shopped at stores such as Lowe's and Costco. The homeowners paid the store, which then contracted with Designer to fabricate and install the countertops. Designer bought materials from Arizona Tile, LLC, on an open account. Designer's only known corporate officers were Howard Berger and John McCarthy. Designer became insolvent and could not pay Arizona Tile for all the materials it had purchased, including materials for which Designer had already received payment from the retail stores. Arizona Tile sued Designer and won a default judgment, but the company had no funds. Arizona Tile then sued Berger and McCarthy personally for diverting company funds that Designer had received in trust for payment to Arizona Tile. Arizona Tile argued that the use of the funds for other purposes was a breach of fiduciary duty. Berger and McCarthy argued that corporate law imposed neither a fiduciary duty on corporate officers nor personal liability for breach of a duty to suppliers of materials. Which argument is more credible and why?
