First, we found the equity beta by locating the market returns for both IBM and the S&P 500 from 2005 to 2014. We chose to go all the way back to 2005 to reflect both good and bad times in the market in our calculations. Equity beta is calculated by taking the covariance of the change in percentages for IBM and the S&P and dividing it by the variance in the percentage change in the S&P. Equity beta, also known as “levered beta” is the beta of the firm with financial leverage, and is used to determine the asset beta of the firm. The asset beta, also known as “unlevered beta” is calculated by taking the equity beta, calculated above, and multiplying it by the ratio of total equity to total value of the firm. By doing so it effectively takes out the financial leverage, unlevering beta. Finally, asset beta is put into the CAPM equation with the same December 2014, 10 year Treasury Bill rate and market risk premium as used in the WACC method giving IBM a discount rate of 4.09% per the asset beta
