However, as will be shown below, the total value of the firm can be calculated with Ku using the Capital Cash Flow, CCF, and no circularities will be present and there is no need to calculate the leverage ratio for every period.
For a better understanding of these ideas, an example is presented. This example is done assuming that the discount rate for TS is Ku. In this example it is assumed that Ku is the correct discount rate for tax savings. The information about the initial investment, free cash flows, debt balances and initial equity is presented in Table 4. The WACC calculations are made estimating the debt and equity participation in the total value of the firm for each period and calculating the contribution of each to the WACC after taxes.
We will construct each table, step by step, assuming that WACC is zero. As said, the first step is to calculate the value with an arbitrary value for WACC, for instance, zero. See this in the next table. For year 2 it will be , We do this to avoid a division by zero.
It is recommended that the last arithmetic operation be the WACC calculation as the sum of the debt and equity contribution to the cost of capital. At this point we recommend to set the spreadsheet to handle circularities following these instructions:. This procedure can be done before starting the work in the spreadsheet or when Excel declares the presence of circularity.
After these instructions are done, then, the WACC can be calculated as the sum of the debt and equity contribution to the cost of capital. Now we can proceed to formulate the WACC as the sum of the two components: debt contribution and equity contribution.
Note that the cost of equity -Ke- is larger than Ku as expected, because Ku is the cost of the stockholder, as if the firm were unlevered 8 8 As MM say that Ku is constant and independent from the capital structure, it will be equal to Ku when debt is zero.
And this is the condition for the validity of the first proposition of MM. When there is debt - Ke calculation - necessarily Ke ends up being greater than Ku, because of leverage. With these values it is possible to calculate the firm value for each period. If Ke 1 is known, as it was said above, Ku is found with 6.
Excel solves the circularity that is found and the same values result. Using 14 and from tables 14 and 10 , we have that the firm value at end of year 3 is , The reader has to realize that the values In this case circularity is generated. This is solved allowing the spreadsheet to make enough iteration until it finds the final numbers. The same result can be reached calculating the present value for the free cash flow assuming no debt and discount it a Ku, or what is the same, at WACC before taxes and add up the present value of tax savings at the same rate of discount, Ku.
Myers and all the finance textbooks teach that the discount rate for the TS should be the cost of debt. However, the tax savings depend on the firm profits. Hence, the risk associated to the tax savings is the same as the risk of the cash flows of the firm rather than the value of the debt. Hence, the discount rate should be Ku. For this reason the tax savings are also discounted at Ku. This way, the present value for the free cash flows discounted at WACC after taxes coincides with the present value of the free cash flow assuming no debt discounted at Ku and added to the present value of the tax savings discounted at the same Ku.
The use of Ku to discount the tax savings has been proposed by Tham , and Ruback Tham proposes to add to the unlevered value of the firm the present value of the FCF at Ku , the present value of the tax savings discounted at Ku. Ruback presents the Capital Cash Flow and discount it at Ku. Notice that the same result is reached with the three methods.
For instance, for year 1, From the point of view of equity valuation, the value is calculated with the present value of the free cash flow discounted at WACC minus the debt at 0. This value also can be reached with the equity cash flow CFE and it is equal to. When the present value of CFE at Ke, is calculated the same result is obtained. This is, , This means that the right discount rate to discount the CFE is Ke, and its discounted value is consistent with the value calculated with the FCF.
In table 13 we calculated the market value of equity using the market value calculated before. However, this is not an independent method when we use the values from other method. In order to calculate the market value of equity in an independent way we will use the same procedure utilized for the calculation with WACC.
The difference is that we will calculate again the value of Ke. The first table with Ke equal to zero is Table Observe that working independently we reach the same values for equity, total value and Ke. The investment from the equity holders was , and hence NPV for them is , There is no surprise that both NPVs are identical.
Summarizing, the different methodologies presented to calculate the total value of the firm are 9 9 There exist other methodologies, but they do not coincide among them. See Taggart Jr. In this example, it is shown in Table The value of equity is the price that the owners would sell their participation in the firm and this is higher than the initial equity contribution of , When using Kd as the discount rate for the TS, we find a higher value and full consistency as we did with the assumption the discount rate for the TS is Ku in this example.
In short, ALL methods if properly calculated yield the same firm and equity value and identical NPV for the firm and for the equity holder. The misuse of WACC might be due to several reasons.
Traditionally there have not been computing tools to solve the circularity problem in WACC calculations. Now it is possible and easy with the existence of spreadsheets.
Not having these computing resources in the previous years it was necessary to use simplifications such as calculating just one single discount rate or in the best of cases to use the book values in order to calculate the WACC. Here a detailed but known methodology to calculate the WACC has been presented taken into account the market values in order to weigh the cost of debt and the cost of equity. By the same token a methodology based on the WACC before taxes Ku, constant assuming stable macroeconomic variables, such as inflation that does not depend on the capital structure of the firm has been presented.
The most difficult task is the estimation of Ku, or alternatively, the estimation of Ke. Here, a methodology to estimate those parameters is suggested. If it is possible to estimate Ku from the beginning, it will be possible to calculate the total and equity value independently from the capital structure of the firm, using the CCF approach or the Adjusted Present Value approach and discounting the tax savings at Ku.
In summary, the different methodologies presented to calculate the total value of the firm are consistent and yield identical values, as presented in Table Fundamentals of corporate finance.

Growth investors may find such companies promising.
However, it may also indicate overvalued or overbought stocks trading at high prices. Sometimes, book valuation and market value are nearly equal to each other. In those cases, the market sees no reason to value a company differently from its assets.
It is equal to the price per share divided by the book value per share. That means the market valuation is less than the book valuation, so the market might undervalue the stock. That tells us the market valuation now exceeds book valuation, indicating potential overvaluation. Most publicly listed companies fulfill their capital needs through a combination of debt and equity. Companies get debt by taking loans from banks and other financial institutions or by floating interest-paying corporate bonds.
They typically raise equity capital by listing the shares on the stock exchange through an initial public offering IPO. Sometimes, companies get equity capital through other measures, such as follow-on issues, rights issues , and additional share sales.
Debt capital requires payment of interest, as well as eventual repayment of loans and bonds. However, equity capital creates no such obligation for the company. Equity investors aim for dividend income or capital gains driven by increases in stock prices. Creditors who provide the necessary capital to the business are more interested in the company's asset value. After all, they are mostly concerned about repayment.
Therefore, creditors use book value to determine how much capital to lend to the company since assets make good collateral. The book valuation can also help to determine a company's ability to pay back a loan over a given time. On the other hand, investors and traders are more interested in buying or selling a stock at a fair price. When used together, market value and book value can help investors determine whether a stock is fairly valued, overvalued, or undervalued.
The book value of a company is equal to its total assets minus its total liabilities. The total assets and total liabilities are on the company's balance sheet in annual and quarterly reports. Book value per share is a way to measure the net asset value that investors get when they buy a share of stock.
Investors can calculate book value per share by dividing the company's book value by its number of shares outstanding. All other things being equal, a higher book value is better, but it is essential to consider several other factors. People who have already invested in a successful company can realistically expect its book valuation to increase during most years.
However, larger companies within a particular industry will generally have higher book values, just as they have higher market values. Furthermore, some businesses are more profitable than others. Such firms can afford to pay a higher dividend yield. That may justify buying a higher-priced stock with less book value per share. The price per book value is a way of measuring the value offered by a firm's shares. It is possible to get the price per book value by dividing the market price of a company's shares by its book value per share.
A lower price per book value provides a higher margin of safety. It implies that investors can recover more money if the company goes out of business. The price-to-book ratio is another name for the price per book value. Both book and market values offer meaningful insights into a company's valuation. Comparing the two can help investors determine if a stock is overvalued or undervalued given its assets, liabilities, and ability to generate income.
Like all financial measurements, the real benefits come from recognizing the advantages and limitations of book and market values. The investor must determine when to use the book value, market value, or another tool to analyze a company. Accessed Nov. Financial Ratios. Tools for Fundamental Analysis.

In practical terms Market Value reflects the theoretical cost of buying all shares of the company. Thus we can say that market value or market capitalization is a measure of the size of the company, whereas book value is a measure of the accounting value of the company.
When the market value of equity is less than book value, value investors would interpret it as an opportunity to invest. This is like a sure shot gain situation.
There is only one situation where the MV less than BV is justified. This situation could be fraudulent accounting and inflated figures of assets on the balance sheet. For example, a high-value machinery which is already obsolete in terms of its technology and has not been written off.
This will keep the book value on a higher side but this value will not be realized if the assets of the business are sold at this time. Effectively, the company has not followed the accounting policies. Conversely, when the market value of equity is more than book value, it implies a strong financial position for the company. It shows that investors believe in strong growth prospects of the company.
This helps a company in obtaining additional capital at favorable prices. First of all, it is an imaginary situation.
