WACC is calculated as the weighted average of the cost of equity and the after-tax cost of debt, using median unlevered betas (5-year monthly, adjusted via Blume) relevered with median net-debt capital structures via the Hamada equation.

Cost of equity = risk-free rate + relevered beta × equity risk premium. Cost of debt = (risk-free rate + credit spread) × (1 − tax rate).
