# Cost equity estimates

Estimate the cost of equity (expressed in percentages or in a decimal format) or the rate of return that Accuray's shareholders 'require'. Use the Capital Asset Pricing Model (CAPM) in order to estimate the rate of return that shareholders require on their investment. Show all calculations.
