Lauderdale Corporation is organized in three geographical divisions $($regions$)$ with managers responsible for revenues, costs, and assets in their respective regions. The firm is highly decentralized and managers are evaluated solely on divisional performance. Corporate overhead $($all fixed$)$ is allocated to the regions based on regional gross margin $($regional revenue minus regional cost of sales$).$
