Levered Beta, often referred to simply as equity beta, is a measure of the risk of a company’s equity, considering the impact of its financial leverage (debt). It represents the sensitivity of the company’s stock returns relative to the returns of the overall market, with adjustments for the company’s debt structure.
Definition
Levered Beta calculates the volatility of a company’s equity with the additional risk due to its debt. It is a crucial metric in the Capital Asset Pricing Model (CAPM), enabling investors to understand the true extent of risk and expected return on an investment.
Mathematically, Levered Beta (\(\beta_l\)) is related to unlevered beta (\(\beta_u\)) through the following formula:
where:
- \( \beta_l \) = Levered Beta
- \( \beta_u \) = Unlevered Beta
- \( T_c \) = Corporate Tax Rate
- \( D \) = Market Value of Debt
- \( E \) = Market Value of Equity
Components of Levered Beta
Unlevered Beta
Unlevered Beta (\(\beta_u\)) measures the risk of the company’s assets without considering debt. It captures the business risk of the firm.
Financial Leverage
Financial leverage magnifies the equity beta, reflecting the additional risk borne by equity investors due to the company’s debt. Higher debt levels typically increase Levered Beta due to the higher risk of bankruptcy and fixed interest obligations.
Corporate Tax Rate
The tax shield provided by interest deductibility reduces the effective leverage impact, hence adjusting the Levered Beta.
Example Calculation
Consider a company with the following characteristics:
- Unlevered Beta (\(\beta_u\)) = 1.2
- Market Value of Debt (\(D\)) = $200 million
- Market Value of Equity (\(E\)) = $300 million
- Corporate Tax Rate (\(T_c\)) = 30%
Using the Levered Beta formula:
Thus, the Levered Beta is approximately 1.760, indicating that the company’s equity is 76% more volatile than the market.
Importance in Investment Decisions
Risk Assessment
Levered Beta helps investors understand the systematic risk of a company’s equity, including the impact of capital structure decisions. Higher Levered Beta suggests higher risk and potentially higher returns.
CAPM and Cost of Equity
Levered Beta is integral to the CAPM formula, which calculates the required return on equity:
where:
- \( R_e \) = Expected Return on Equity
- \( R_f \) = Risk-Free Rate
- \( R_m \) = Market Return
- \( \beta_l \) = Levered Beta
