Tantasqua Paper Products Is Composed of 3 Divisions: Industrial Paper

Tantasqua Paper Products is composed of 3 divisions: industrial paper products, commercial paper products, and a forestry division which grows trees for wood pulp used in the paper-making process. Each of these divisions takes on a large number of projects with differing risk characteristics. Tantasqua now uses a single discount rate based on the company's WACC to evaluate all capital budgeting proposals. Discuss the advantages and disadvantages of switching to an approach based on separate discount rates for each division or even the risk level of each project.
