Calculate the WACC for Starbucks (SBUX). Use Yahoo! Finance for the stock's beta and market cap, and find reasonable estimates for the market risk premium and risk-free rate. For each of these, note your source and provide a sentence or two explanation for why it is a reasonable estimate. Use the debt data that is available from the 2018 10-k on EDGAR. Use the estimate of total market value of debt to calculate its weight (ignoring issuance costs/amortization and hedging). Assume a tax rate of 30% in your calculation. Put all of the needed data in Excel, and create a separate sheet in the file for each of your calculations of the costs of (1) debt, (2) equity, and (3) WACC.
