Firm Valuation Approaches

The Cost of Capital Approach, The Adjusted Present Value (APV) Approach, Cost of Capital Vs. APV Valuation.

This topic compares two primary approaches to firm valuation: the Cost of Capital approach and the Adjusted Present Value (APV) approach. Both aim to estimate the enterprise value of a company, but they differ in how they handle the effects of financing, particularly debt.

1. The Cost of Capital Approach:

  • Overview: This is the most common approach to firm valuation, and it's essentially what we covered in Topic 7 using FCFF. It involves discounting the free cash flow to the firm (FCFF) at the weighted average cost of capital (WACC).
  • Key Steps:
    1. Forecast FCFF: Project the company's future free cash flows to the firm (FCFF).
    2. Calculate WACC: Determine the company's weighted average cost of capital, which reflects the average rate of return required by all investors (debt and equity holders).
    3. Discount FCFF: Discount the forecasted FCFF at the WACC to arrive at the enterprise value.
    4. Add Non-Operating Assets: Include the value of any non-operating assets (e.g., excess cash, marketable securities).
    5. Subtract Debt (to get Equity Value): If you want the equity value, subtract the market value of debt from the enterprise value.
  • Assumptions: The key assumption is that the company's capital structure (the proportions of debt and equity) remains relatively constant over the forecast period. If the capital structure is expected to change significantly, the WACC should be adjusted accordingly. Also, this assumes that the business risk of the projects the firm undertakes is the same.
  • Advantages:
    • Relatively simple to apply.
    • Widely understood and accepted.
  • Disadvantages:
    • The assumption of a constant capital structure may not be realistic.
    • WACC can be difficult to estimate accurately, especially for companies with complex capital structures.
    • Can be inappropriate if a company's debt policy is highly variable or tied to specific projects.

2. The Adjusted Present Value (APV) Approach:

  • Overview: The APV approach values the firm by first calculating the value of the firm as if it were entirely equity-financed (i.e., unlevered) and then adding the present value of any tax shields or other benefits resulting from debt financing.
  • Key Steps:
    1. Calculate the Unlevered Value: Discount the FCFF at the unlevered cost of equity (Ku), which is the cost of equity the company would have if it had no debt. This provides the base value of the firm.
    2. Calculate the Value of Tax Shields: Determine the present value of the tax shields created by the company's debt financing. Tax shields arise because interest expense is tax-deductible.
    3. Calculate the Value of Other Financing Side Effects: Consider any other financing side effects (e.g., costs of financial distress, subsidies associated with debt).
    4. Calculate APV: Sum the unlevered value, the present value of the tax shields, and the value of other financing side effects to arrive at the adjusted present value of the firm.
  • Formula: APV = Unlevered Value + PV of Tax Shields + PV of Other Financing Side Effects
  • Assumptions: The primary assumption is that the firm's debt policy is known and can be reliably forecasted.
  • Advantages:
    • More flexible than the WACC approach when dealing with changing capital structures or complex debt policies.
    • Explicitly accounts for the value of tax shields and other financing side effects.
  • Disadvantages:
    • More complex to apply than the WACC approach.
    • Requires making more assumptions about the company's debt policy and tax rate.
    • The separation of operating and financing effects might be artificial in some circumstances.

3. Cost of Capital vs. APV Valuation:

Feature Cost of Capital Approach (WACC) Adjusted Present Value (APV) Approach
Discount Rate Weighted Average Cost of Capital (WACC) Unlevered Cost of Equity (Ku) for base value, then separate discounting.
Treatment of Debt Implicitly incorporated in WACC. Explicitly considers the value of tax shields and other debt-related effects.
Capital Structure Assumes a relatively stable target capital structure. More flexible with changing or complex capital structures.
Complexity Simpler to apply. More complex to apply.
When to Use When capital structure is relatively stable and predictable. When capital structure is expected to change significantly or when the value of tax shields is a major factor.
Key Assumption Target debt-to-value ratio is constant over the forecasting period. Forecasts of debt levels are reasonably reliable.

In summary:

  • The Cost of Capital (WACC) approach is a simpler method that is well-suited for valuing companies with stable capital structures. It values operations and financing together using WACC as the discount rate.

  • The Adjusted Present Value (APV) approach is a more flexible method that is better suited for valuing companies with changing capital structures or complex debt policies. It values the business as if it were all equity, and then adds the impact of financing (primarily the tax shield).

The choice between the two approaches depends on the specific circumstances of the company being valued. In many cases, both approaches will produce similar results, but the APV approach may provide more insight into the impact of financing decisions on firm value.
