Exercise 11

Economic Earnings
A large consulting firm is looking to expand the services currently offered its clients. The firm has developed a new performance metric called "Economic Earnings," or EE for short. The performance metric is argued to be a better measure of both divisional performance and firmwide performance, and hence "a more rational platform for compensating employees and managers." The consulting firm is seeking to convince clients they should replace their current metrics, such as accounting net income, ROA, EVA, and so forth, with EE.
EE starts with traditional accounting net income but then makes a series of adjustments. The primary adjustment is to add back depreciation and then subtract a required return on invested capital. The consultants argue for adding accounting depreciation back because it is a sunk cost. It does not represent a current cash flow. For example, suppose a client has accounting net income calculated as: Suppose the client has total assets of $6,000 and a risk-adjusted weighted-average cost of capital (WACC) of 25 percent. Then this client's EE is calculated as follows:
