ExxonMobil (Xom)
Would you recommend that ExxonMobil use a single company- wide cost of capital for analyzing capital expenditures in all its business units? Why or why not?
To start with, a single company-wide cost of capital implies that the firm uses one general cost of capital as the discounting rate for all of the capital expenditures within its business operations irrespective of whether they come from different departments. The recommendation for Exxon Mobil is that it should not make use of a single company-wide cost of capital when analyzing capital expenditures for all of its business units. Instead, the company should make use divisional cost of capital for each business unit independently when undertaking an analysis for capital expenditures (California State University, n.d).

The reason being, if the company employs a distinctive single company-wide cost of capital or discounting rate, then the company may, resultantly overinvest in business units that have a higher market beta compared to the core industry beta of the company. At the same time, the company may under-invest in business units that have a lower market beta compared to the core industry beta of the company (Kruger et al., 2011).
What is more, results of substantial differences in the discounting rate or costs of capital across the different business lines have indicated that making use of a single company-wide cost of capital is by and large not suitable or fitting. Using a single company- wide cost of capital would cause different departments to miss…
