What duties did Brock, as a director, owe to Firm Body? David Brock is on the board of directors of Firm Body Fitness, Inc., which owns a string of fitness clubs in New Mexico. Brock owns 15 percent of the Firm Body stock and is also employed as a tanning technician at one of the fitness clubs. After the January financial report showed that Firm Body’s tanning division was operating at a substantial net loss, the board of directors, led by Marty Levinson, discussed the possibility of terminating the tanning operations. Brock successfully convinced a majority of the board that the tanning division was necessary to market the clubs’ overall fitness package. By April, the tanning division’s financial losses had risen. The board hired a business analyst, who conducted surveys and determined that the tanning operations did not significantly increase membership. A shareholder, Diego Penada, discovered that Brock owned stock in Sunglow, Inc., the company from which Firm Body purchased its tanning equipment. Penada notified Levinson, who privately reprimanded Brock. Shortly thereafter Brock and Mandy Vail, who owned 37 percent of the Firm Body stock and also held shares of Sunglow, voted to replace Levinson on the board of directors.
