Estimating the Weighted Average Cost of Capital To value operations, discount cash flow at the weighted average cost of capital. The WACC incorporates the required return from all sources of capital into a single number. Exhibit H.15: Weighted Average Cost of Capital. Net of excess cash, Costco uses less debt than any of its industry peers. With this in mind, we assume that Costco will disgorge excess cash and set their target debt-to-value ratio to their current debt-to-value as measured on a gross basis. Likewise, when we estimate the cost of debt and cost of equity, we use the same debt-to-value ratio. For a comprehensive discussion of the cost of capital, see Chapter 15. Valuing the Enterprise and Converting to Equity To value Costco, we use both enterprise DCF and discounted economic profit. Free cash flow (FCF) models measure how cash flows in and out of the com- pany, regardless of accounting. Economic profit links better to value creation. Implemented correctly, both models will lead to the same valuation result. Exhibit H.16: Enterprise DCF Valuation. To arrive at the present value of cash flow, we sum each year’s discounted FCF with the discounted value of continuing value. Then we adjust the resulting value by half a year to estimate the value of operations, reflecting that cash flows are generated throughout the year. To the value of operations, we add any nonoperating assets that are excluded from free cash flow—in this case, excess cash and the value of tax loss carryforwards. For simplicity, we value tax loss carryforwards at book value less the valuation allowance. Do not add other deferred-tax assets, such as those related to equity com- pensation or deferred membership fees, to the value of operations. The value of these tax assets is already incorporated into NOPAT using cash-based taxes. Consequently, they are classified as an equity equivalent and ignored. To estimate intrinsic equity value, subtract debt and debt equivalents from enterprise value. This includes all debt, capitalized operating leases, and noncontrolling interests. While we use the book values for ease of exposition, use the market value of each account when available. Dividing equity value by the number of shares leads to a value of almost $220 per share, which matches the share price in early 2019. For more on converting enterprise value into equity value by adding nonoperating assets and subtracting debt equivalents, see Chapter 16. Appendix H  841 Exhibit H.17: ROIC and Economic Profit. A robust valuation will focus not only on the resulting share price, but also on the critical value drivers that result from the model. Exhibit H.17 presents ROIC and economic profit by year. When benchmarking across companies or over time, we usually calcu- late ROIC using a two-year average of invested capital. In this situation, we calculate ROIC using invested capital from the beginning of the year, in order to create an economic-profit valuation that matches the results from enterprise DCF. In this exhibit, we present only a high-level analysis of performance. For more on how to disaggregate and assess ROIC in depth, see Chapter 12. Exhibit H.18: Valuation Using Economic Profit. To determine the value of operations, add discounted economic profit to invested capital. As expected, an economic-profit-based valuation leads to the same value of operations as an enterprise DCF valuation. Putting the Model to Work While the valuation model is complete, a good financial analyst or investor will now put it to work. Ask yourself several questions: Which variables are the most critical to value? What is the value if performance remains unchanged? How does this value differ from one based on other forecasts? What is the value with proposed improvements? Are there scenarios that may provide additional insights on various strategies? A model is more than its resulting valuation. As we discuss in Chapter 17, the most important insights are the ones you develop by testing alternatives and creating scenarios.
