I cannot seem to start a valuation. In order to calculate E + D = VA (FCF; WACC) I need the WACC and in order to calculate the WACC I need D and E. Where should I start? (Finance Interview Questions With Answers)

The Circular Dependency of Valuation: A Guide to Breaking the Cycle

In the realm of finance, valuation is a fundamental concept that involves determining the intrinsic worth of an asset or company. One of the most common valuation methods is the discounted cash flow (DCF) analysis, which relies on the principle of discounting future cash flows to their present value. However, a common challenge faced by analysts and investors is the circular dependency that arises when calculating the weighted average cost of capital (WACC), a crucial input for the DCF model.

The WACC is the average cost of all the capital a company uses, including debt and equity. It represents the minimum return that a company must earn on its investments to satisfy its investors. The formula for calculating WACC is:

WACC = (E/V) * Re + (D/V) * Rd * (1 – Tc)

Where:

  • E = Market value of equity
  • D = Market value of debt
  • V = Total value of the company (E + D)
  • Re = Cost of equity
  • Rd = Cost of debt
  • Tc = Corporate tax rate

The circular dependency arises because the WACC calculation requires the market value of equity (E) and debt (D), which are themselves derived from the valuation process. This creates a chicken-and-egg scenario where you need the WACC to calculate the valuation, but you need the valuation to calculate the WACC.

Breaking the Circular Dependency: A Practical Approach

While the circular dependency may seem like an insurmountable obstacle, there are practical approaches to break the cycle and arrive at a reasonable valuation. Here’s a step-by-step guide:

1. Start with an Initial Estimate of WACC

Begin by making an initial estimate of the WACC based on comparable companies or industry averages. This initial estimate should be a reasonable starting point for your analysis. You can use publicly available data from financial databases or industry reports to gather information on comparable companies’ WACCs. For example, if you are valuing a technology company, you can look at the WACCs of other publicly traded technology companies with similar risk profiles.

2. Calculate the Initial Valuation

Using your initial WACC estimate, perform a preliminary DCF analysis to arrive at an initial valuation of the company. This initial valuation will provide you with a starting point for refining your WACC calculation.

3. Update the WACC

Based on the initial valuation, update your WACC calculation by using the derived market values of equity and debt. This updated WACC will be more accurate than your initial estimate, as it incorporates the valuation results.

4. Iterate the Process

Repeat steps 2 and 3 until the WACC and valuation converge. This iterative process ensures that the WACC and valuation are consistent with each other. You can continue iterating until the difference between consecutive WACC calculations is negligible.

Example: Valuing a Hypothetical Company

Let’s consider a hypothetical company, “TechCorp,” which is planning to go public. We want to determine its valuation using the DCF method. We start by gathering information on comparable companies in the technology sector and estimate an initial WACC of 10%. Using this WACC, we perform a DCF analysis and arrive at an initial valuation of $1 billion. Based on this valuation, we update the WACC using the derived market values of equity and debt. This updated WACC might be 9.5%, reflecting the company’s specific risk profile. We then repeat the DCF analysis with the updated WACC and continue iterating until the WACC and valuation converge.

Key Takeaways

The circular dependency between WACC and valuation is a common challenge in financial analysis. However, by following a practical approach that involves initial estimates, iterative calculations, and convergence analysis, you can break the cycle and arrive at a reasonable valuation. Remember that the accuracy of your valuation depends on the quality of your inputs and the rigor of your analysis. It’s essential to use reliable data, consider all relevant factors, and be transparent about your assumptions.
