Degree of financial leverage

What Is Degree of Financial Leverage?

The degree of financial leverage (DFL) is a corporate finance metric that measures the sensitivity of a company's earnings per share (EPS) to changes in its operating income. It quantifies the magnification effect that fixed financing costs, primarily interest expense from debt financing, have on a company's net income and, consequently, its EPS. Financial leverage is a core component within the broader field of corporate finance, reflecting how a firm structures its assets and liabilities. The effective use of the degree of financial leverage can significantly impact shareholder wealth, as it indicates how much additional profit a company can generate for its shareholders by employing borrowed capital.

History and Origin

The concept of financial leverage, broadly defined as the use of borrowed capital to amplify returns, has been integral to business and investment for centuries. The specific quantification through metrics like the degree of financial leverage evolved as financial analysis became more sophisticated in the 20th century. Early financial theories, such as the Modigliani-Miller theorem, published in the late 1950s and early 1960s, provided foundational insights into the relationship between a company's capital structure, its cost of capital, and firm value, laying the groundwork for understanding the impact of debt on equity returns. These theories highlighted that while debt can offer tax advantages, it also introduces financial risk9. Over time, practitioners and academics developed specific ratios and metrics, including the degree of financial leverage, to better assess and manage this risk-return trade-off. Global debt levels, influenced by various factors, are regularly monitored by institutions like the International Monetary Fund (IMF), which provides extensive data through its Global Debt Database, showcasing the pervasive nature of leverage in modern economies7, 8.

Key Takeaways

  • The degree of financial leverage (DFL) measures how changes in operating income affect a company's earnings per share (EPS).
  • It highlights the impact of fixed financing costs, such as interest expense, on shareholder returns.
  • A higher DFL indicates greater sensitivity of EPS to changes in operating income and suggests higher financial risk.
  • Companies use financial leverage to potentially boost return on equity by employing borrowed capital.
  • Assessing DFL is crucial for investors and analysts to understand a company's financial stability and risk profile.

Formula and Calculation

The degree of financial leverage (DFL) is calculated using the following formula:

DFL=EBITEBIT−IDFL = \frac{EBIT}{EBIT - I}

Where:

  • EBIT = Earnings Before Interest and Taxes (Operating Income)
  • I = Interest Expense

Alternatively, it can also be expressed as:

DFL=%ΔEPS%ΔEBITDFL = \frac{\% \Delta EPS}{\% \Delta EBIT}

Where:

  • %ΔEPS = Percentage change in earnings per share
  • %ΔEBIT = Percentage change in Earnings Before Interest and Taxes

This formula demonstrates that DFL quantifies the percentage change in EPS for a given percentage change in EBIT, isolating the impact of financing decisions from operational performance. A company's net income is directly affected by interest payments, which are fixed costs associated with debt.

Interpreting the Degree of Financial Leverage

Interpreting the degree of financial leverage involves understanding the relationship between a company's operating performance and its bottom-line results for shareholders. A DFL value greater than 1 indicates the presence of financial leverage. For example, a DFL of 2.0 means that a 1% change in operating income will result in a 2% change in earnings per share.

A higher DFL implies that a company is using a significant amount of debt in its capital structure. While this can magnify positive returns during periods of strong operating income, it also amplifies losses when operating income declines. Therefore, a high DFL is often associated with higher financial risk. Conversely, a DFL closer to 1 suggests that a company relies less on debt financing and more on equity financing, resulting in less volatile earnings per share in response to changes in operating income. Analysts use this metric to assess a company's financial health and its susceptibility to economic downturns.

Hypothetical Example

Consider two companies, Company A and Company B, with the following financial data:

Company A (Low Leverage)

  • Operating Income (EBIT): $1,000,000
  • Interest Expense: $50,000

Company B (High Leverage)

  • Operating Income (EBIT): $1,000,000
  • Interest Expense: $400,000

Let's calculate the DFL for both:

For Company A:

DFLA=$1,000,000$1,000,000−$50,000=$1,000,000$950,000≈1.05DFL_A = \frac{\$1,000,000}{\$1,000,000 - \$50,000} = \frac{\$1,000,000}{\$950,000} \approx 1.05

For Company B:

DFLB=$1,000,000$1,000,000−$400,000=$1,000,000$600,000≈1.67DFL_B = \frac{\$1,000,000}{\$1,000,000 - \$400,000} = \frac{\$1,000,000}{\$600,000} \approx 1.67

Now, suppose operating income for both companies increases by 10% to $1,100,000.

Company A (New Net Income before taxes):
$1,100,000 - $50,000 = $1,050,000$
Percentage change in net income: $($1,050,000 - $950,000) / $950,000 \approx 10.53%$
This is approximately 10% (the operating income change) multiplied by Company A's DFL of 1.05.

Company B (New Net Income before taxes):
$1,100,000 - $400,000 = $700,000$
Percentage change in net income: $($700,000 - $600,000) / $600,000 \approx 16.67%$
This is approximately 10% (the operating income change) multiplied by Company B's DFL of 1.67.

As demonstrated, the 10% increase in operating income resulted in a larger percentage increase in net income for Company B due to its higher degree of financial leverage. This example illustrates how fixed interest costs can amplify the effect of changes in operating income on the profitability available to shareholders.

Practical Applications

The degree of financial leverage is a crucial tool in various financial contexts, from investment analysis to regulatory oversight. In investment analysis, analysts use DFL to gauge the risk profile of a company's stock. Companies with high DFL might offer greater potential returns during economic booms but carry increased risk during downturns, which could lead to financial distress or even bankruptcy.

For corporate management, understanding DFL helps in making strategic decisions regarding capital structure and financing. It informs whether to take on more debt to fund expansion or rely on equity. Regulators, such as the U.S. Securities and Exchange Commission (SEC), emphasize transparent disclosure of financial information, including leverage, to protect investors and ensure market stability. 4Furthermore, the study of financial leverage helps in comprehending how capital costs are impacted by financing strategies, aiming for optimal profitability and corporate value growth. 3This metric is particularly relevant in industries with high fixed costs or those undergoing significant capital expenditures.

Limitations and Criticisms

While the degree of financial leverage is a valuable metric, it has limitations. A primary criticism is that it only considers the impact of interest expense and does not account for all aspects of a company's financial risk. For instance, it doesn't directly incorporate the volatility of the company's operating income itself, which is influenced by operational factors.

Excessive reliance on high financial leverage can lead to severe financial distress, particularly during economic downturns or periods of rising interest rates. Companies with a high DFL may face difficulty servicing their debt obligations if their operating income declines unexpectedly. This can trigger a cascade of negative effects, including credit rating downgrades, increased borrowing costs, and, in extreme cases, liquidation. Moreover, the metric is static, representing a snapshot based on historical data from the balance sheet and income statement. It does not inherently predict future changes in debt levels or interest rates. Academic research consistently highlights that while moderate leverage can enhance returns, excessive leverage significantly increases the risk of financial crises for companies. 2Furthermore, the consequences of high financial leverage can extend to stakeholders, potentially impacting sales growth and employment costs.

Degree of Financial Leverage vs. Degree of Operating Leverage

The degree of financial leverage (DFL) and the degree of operating leverage (DOL) are both critical tools in financial analysis, but they measure different aspects of a company's risk and profitability.

DFL focuses on the impact of a company's financing decisions, specifically how fixed costs related to debt (like interest expense) amplify changes in operating income into larger changes in earnings per share. It reflects financial risk—the risk that a company may not be able to meet its financial obligations.

In contrast, DOL measures the sensitivity of a company's operating income to changes in sales revenue, driven by the proportion of fixed costs versus variable costs in its operational structure. A high DOL indicates that a small change in sales can lead to a large change in operating income. This reflects operational risk—the risk inherent in the business's day-to-day activities.

While DFL examines the lower portion of the income statement, from EBIT to EPS, DOL examines the upper portion, from sales to EBIT. Both metrics, when combined to form the degree of total leverage, provide a comprehensive view of how a company's sales ultimately impact its earnings per share.

FAQs

What does a high DFL indicate?

A high degree of financial leverage indicates that a company relies heavily on debt financing. This means that a small change in its operating income can lead to a disproportionately larger change in its earnings per share, magnifying both potential gains and losses for shareholders.

Is financial leverage always bad?

No, financial leverage is not inherently bad. When used prudently, it can significantly enhance the return on equity for shareholders by utilizing borrowed capital at a cost lower than the returns generated by the assets it finances. However, excessive financial leverage increases financial risk and can lead to distress if a company's operating performance declines.

How does DFL relate to a company's capital structure?

The degree of financial leverage is directly influenced by a company's capital structure, specifically the proportion of debt versus equity. A higher proportion of debt in the capital structure generally results in a higher DFL, reflecting greater reliance on borrowed funds and their associated fixed interest costs.
