    The Cost of Capital: An Overview

    Cost of capital is the weighted average ofthe required returns of the securities thatare used to finance the firm. We refer to

    this as the firms Weighted Average Costof Capital, or WACC.

    The Cost of Capital: An Overview(cont.)

    Most firms raise capital with a combinationof debt, equity, and hybrid securities.

    WACC incorporates the required rates ofreturn of the firms lenders and investorsand the particular mix of financing sourcesthat the firm uses.

    The Cost of Capital: An Overview(cont.)

    How does riskiness of firm affect WACC?

    Required rate of return on securities will be

    higher if the firm is riskier.

    Risk will influence how the firm chooses tofinance i.e. proportion of debt and equity.

    The Cost of Capital: An Overview(cont.)

    WACC is useful in a number of settings:

    WACC is used to value the firm.

    WACC is used as a starting point for

    determining the discount rate for investmentprojects the firm might undertake.

    WACC is the appropriate rate to use whenevaluating performance, specifically whether

    or not the firm has created value for itsshareholders.

    Three Step Procedure for EstimatingFirm WACC

    1. Define the firms capital structure bydetermining the weight of each source ofcapital. (see column 2, figure 14-2)

    2. Estimate the opportunity cost of eachsource of financing. We will use thecurrent market value of each source ofcapital based on its current, not historical,

    costs. (see column 3, figure 14-2)

    Determining the Firms CapitalStructure Weights

    The weights are based on the followingsources of capital: debt (short-term andlong-term), preferred stock and common

    equity.

    Liabilities such as accounts payable andaccrued expenses are not included incapital structure.

    Determining the Firms CapitalStructure Weights (cont.)

    Ideally, the weights should be based onobserved market values. However, not allmarket values may be readily available.

    Hence, we generally use book values fordebt and market values for equity.

    Checkpoint 14.1

    Calculating the WACC for Templeton Extended CareFacilities, Inc.In the spring of 2010, Templeton was considering the acquisition of a chain ofextended care facilities and wanted to estimate its own WACC as a guide tothe cost of capital for the acquisition. Templetons capital structure consists ofthe following:

    Checkpoint 14.1

    Calculating the WACC for Templeton Extended CareFacilities, Inc. (Cont.)Templeton contacted the firms investment banker to get estimates of thefirms current cost of financing and was told that if the firm were to borrowthe same amount of money today, it would have to pay lenders 8%;however, given the firms 25% tax rate, the after-tax cost of borrowing wouldonly be 6% 8%(1.25). Preferred stockholders currently demand a 10% rateof return, and common stockholders demand 15%. Templetons CFO knewthat the WACC would be somewhere between 6% and 15% since the firmscapital structure is a blend of the three sources of capital whose costs arebounded by this range.

    Checkpoint 14.1:Check Yourself

    After completing her estimate of Templetons WACC, the CFOdecided to explore the possibility of adding more low-costdebt to the capital structure. With the help of the firmsinvestment banker, the CFO learned that Templeton couldprobably push its use of debt to 37.5% of the firms capitalstructure by issuing more debt and retiring (purchasing) thefirms preferred shares. This could be done withoutincreasing the firms costs of borrowing or the required rateof return demanded by the firms common stockholders.What is your estimate of the WACC for Templeton under thisnew capital structure proposal?

    Step 4: Analyze

    We observe that as Templeton chose toincrease the level of debt to 37.5% andretire the preferred stock, the WACC

    decreased marginally from 12.125% to11.625%.

    Thus altering the weights will change theWACC.

    The Cost of Debt

    The cost of debt is the rate of return thefirms lenders demand when they loanmoney to the firm.

    Note, the rate of return is not the same ascoupon rate, which is the rate contractuallyset at the time of issue.

    We can estimate the markets required rate

    of return by examining the yield tomaturity on the firms debt.

    Because of this, it is a standard practice toestimate the cost of debt using yield tomaturity on a portfolio of bonds withsimilar credit rating and maturityas the

    firms outstanding debt.

    The Cost of Common Equity

    The cost of common equity is the rate ofreturn investors expect to receive frominvesting in firms stock. This return comes

    in the form of cash distributions ofdividends and cash proceeds from the saleof the stock.

    The Cost of Common Equity (cont.)

    Cost of common equity is harder toestimate since common stockholders donot have a contractually defined return

    (similar to interest on bonds or dividendson preferred stock). There are twoapproaches to estimating the cost ofcommon equity:

    Dividend growth model (introduced in chapter10)

    CAPM (introduced in chapter 8)

    The Dividend Growth Model Discounted Cash Flow Approach

    Using this approach, we estimate theexpected stream of dividends as thesource of future estimated cash flows.

    We use the estimated dividends andcurrent stock price to calculate the internalrate of return on the stock investment.This return is used as an estimate of cost

    of equity.

    Copyright 2011 Pearson Prentice Hall. All rights reserved. 14-61

    The Capital Asset Pricing Model(cont.)

    Equation 14-4 illustrates that the expectedreturn on common stock is determined bythree key ingredients:

    The risk-free rate of interest, The beta or systematic risk of the common

    stock returns, and

    The market risk premium.

    Copyright 2011 Pearson Prentice Hall. All rights reserved. 14-62

    Advantages of the CAPM approach

    1. The model is simple to understand anduse.

    2. The model does not depend on dividendsor growth rate so it can be applied tocompanies that do not currently paydividends or are not expected to

    experience a constant rate of growth individends.

    Disadvantages of the CAPM

    Disadvantages of the CAPMApproach

    1. CAPM does not offer any guidance on theappropriate choice for the risk-free rate.Risk-free rate may vary widely dependingon the Treasury security chosen.

    2. Estimates ofbeta can vary widelydepending upon the market index andtime period chosen.

    3. Estimates ofmarket risk premium will alsovary depending on the time period andsecurity chosen.

    However, there can be wide variation inthe estimates for each one of thesevariables.

    Here we are given the following estimates: The risk-free rate of interest (.03% or 3.73%)

    The beta or systematic risk of the commonstock returns (1 or 1.5)

    The market risk premium (4% or 8%)

    Estimating Project Cost of Capital

    Should the firms WACC be used toevaluate all new investments?

    In theory, it is appropriate only if the risk ofthe new project is equal to the overall risk ofthe firm. This may generally not be the casenecessitating the need for a unique cost ofcapital for each project.

    However, a recent survey found that morethan 50% of the firms tend to use single,company-wide discount rate to evaluate allof their investment proposals.

    There are advantages and costs associatedwith estimating a unique discount rate for

    each project.

    Multiple discount rates is consistent withfinance theory that suggests that uniquediscount rate will reflect the unique risk ofthe investment.

    Estimating Divisional WACCs

    If a firm undertakes investment with verydifferent risk characteristics, it will try toestimate divisional WACCs.

    The divisions are generally defined bygeographical regions (e.g., Asian regionversus European region) or industry.

    Estimating Divisional WACCs (cont.)

    Advantages of a divisional WACC: The discount rate reflects the risk of projects

    evaluated by different divisions.

    It requires estimating only one cost of capitalestimate for the entire division (rather thanone for each project).

    It limits managerial latitude and the attendantinfluence costs.

    Here a firm with multiple divisions mayidentify a comparable firm with only onedivision (called a pure play firm).

    The estimate of pure play firms cost ofcapital can then be used as a proxy forthat particular divisions cost of capital.

    and Limitations

    While divisional WACC is an improvementover a single, company-wide WACC, it hasa number of limitations:

    1. The sample of firms in a given industry mayinclude firms that are not good matches forthe firm or one of its divisions.

    2. The division being analyzed may not have acapital structure that is similar to the sample

    of firms in the industry data.

    Floatation costs are costs incurred by afirm when it raises money to finance newinvestments by selling bonds and stocks.

    For example, these costs may include feespaid to an investment banker, and costsincurred when securities are sold at a

    discount to the current market price.

    Incorporating Flotation Costs into theCalculation of NPVThe Tricon Telecom Company is considering a $100 millioninvestment that would allow it to develop fiber optic high-speedInternet connectivity to its 2 million subscribers. The investment willbe financed using the firms desired mix of debt and equity with 40%

    debt financing and 60% common equity financing. The firmsinvestment banker advised the firms CFO that the issue costsassociated with debt would be 2% while the equity issue costs wouldbe 10%.

    Tricon uses a 10% cost of capital to evaluate its telecom investmentsand has estimated that the new fiber optic project will yield futurecash flows valued at $115 million. However, to this point noconsideration has been given to the effect of the costs of raising thefinancing for the project or flotation costs. Should the firm go forwardwith the investment in light of the flotation costs?
