Cost of Capital and Allowed Rates of Return
Overview

Publications

The Brattle Group has developed innovative methods to estimate the cost of capital at a line-of-business level for companies considering vertical disintegration, for firms entering foreign markets, and for companies facing radical changes to their cost structure. These techniques supplement traditional measures (such as DCF or CAPM) with structured models of risk and careful analogies to other industries or time frames.

We frequently provide expert testimony before regulatory bodies, courts, and arbitration panels regarding appropriate cost of capital, allowed rate of return, and discount rate.
