Understanding the Degree of Financial Leverage (DFL)
The Degree of Financial Leverage (DFL) is a financial ratio that measures how much a company’s earnings per share (EPS) can be affected by changes in its operating income (EBIT). It provides a quantitative measure of the company’s financial leverage and offers an insight into the risk associated with the firm’s capital structure.
Formula and Calculation of DFL
The DFL can be calculated using two main formulas:
DFL as the ratio of percentage changes:
- \( \text{DFL} = \frac{% \text{ change in EPS}}{% \text{ change in EBIT}} \)
DFL using earnings before interest and taxes:
- \( \text{DFL} = \frac{\text{EBIT}}{\text{EBIT} - \text{Interest}} \)
These formulas help determine how sensitive the EPS is to changes in EBIT, which is crucial for financial planning and risk management.
Practical Use and Industry Variations
DFL is particularly useful for assessing the potential volatility in earnings caused by the company’s use of debt. Industries that commonly operate with high leverage include retail stores, airlines, and utility companies. The ratio helps in understanding how changes in operational earnings could magnify the effects on earnings per share, beneficial during times of economic growth and a point of concern during downturns.
Example Walkthrough: BigBox Inc.
To illustrate, consider BigBox Inc., which has an initial EBIT of $100 million and interest expenses of $10 million. With 100 million shares outstanding, the EPS can be calculated as follows:
- \( \text{EPS} = \frac{$100, \text{million} - $10, \text{million}}{100, \text{million shares}} = $0.90 \)
If BigBox experiences a 20% increase in EBIT (now $120 million), while the interest expense remains at $10 million:
- \( \text{EPS} = \frac{$120, \text{million} - $10, \text{million}}{100, \text{million shares}} = $1.10 \)
The DFL calculated here shows how sensitive the EPS is to changes in EBIT, indicating how a 20% increase in EBIT resulted in more than a proportional increase in EPS.
Key Takeaways and Risks
A high DFL suggests greater potential volatility in EPS, which might be lucrative during economic growth but poses significant risks during financial downturns. Understanding and managing DFL is crucial for maintaining a balanced financial risk profile.
