The Equity Risk Premium (ERP) is a key input used to calculate the cost of capital within the context of the Capital Asset Pricing Model (“CAPM”) and other models. Kroll regularly reviews fluctuations in global economic and financial market conditions that warrant a periodic reassessment of the ERP and the accompanying risk-free rate.
