Briefly explain why the cost of new common equity is higher than the cost of retained earnings, calculate the cost of new common equity, and calculate the retained earnings breakpoint—which is the point where new common equity would have to be issued. Calculate the firm’s composite, or weighted average, cost of capital. Identify some of the factors that affect the WACC—dividing them into factors the firm cannot control and those they can. Briefly explain how firms should evaluate projects with different risks, and the problems encountered when divisions within the same firm all use the firm’s composite WACC when considering capital budgeting projects.

List some problems with cost of capital estimates.

Lecture Suggestions

Chapter 10 uses the rate of return concepts covered in previous chapters, along with the concept of the weighted average cost of capital (WACC), to develop a corporate cost of capital for use in capital budgeting. We begin by describing the logic of the WACC, and why it should be used in capital budgeting. We next explain how to estimate the cost of each component of capital, and how to put the components together to determine the WACC. We go on to discuss factors that affect the WACC and how to adjust the cost of capital for risk. We conclude the chapter with a discussion on some problems with cost of capital estimates. What we cover, and the way we cover it, can be seen by scanning the slides and Integrated Case solution for
Chapter 10, which appears at the end of this chapter solution. For other suggestions about the lecture, please see the “Lecture Suggestions” in Chapter 2, where we describe how we conduct our classes.

10-2An increase in the risk-free rate will increase the cost of debt. Remember from Chapter 6, r = rRF + DRP + LP + MRP. Thus, if rRF increases so does r (the cost of debt). Similarly, if the risk-free rate increases so does the cost of equity. From the CAPM equation, rs = rRF + (rM – rRF)b. Consequently, if rRF increases rs will increase too.

10-3Each firm has an optimal capital structure, defined as that mix of debt, preferred, and common equity that causes its stock price to be maximized. A value-maximizing firm will determine its optimal capital structure, use it as a target, and then raise new capital in a manner designed to keep the actual capital structure on target over time. The target proportions of debt, preferred stock, and common equity, along with the costs of those components, are used to calculate the firm’s weighted average cost of capital, WACC. The weights could be based either on the accounting values shown on the firm’s balance sheet (book values) or on the market values of the different securities. Theoretically, the weights should be based on market values, but if a firm’s book value weights are reasonably close to its market value weights, book value weights can be used as a proxy for market value weights. Consequently, target market value weights should be used in the WACC equation. 10-4In general, failing to adjust for differences in risk would lead the firm to accept too many risky projects and reject too many safe ones. Over time, the firm would become more risky, its WACC would increase, and its shareholder value would suffer. The cost of capital for average-risk projects would be the firm’s cost of capital, 10%. A somewhat higher cost would be used for more risky projects, and a lower cost would be used for less risky ones. For example, we might use 12% for more risky projects and 9% for less risky projects. These choices are arbitrary.

10-5The cost of retained earnings is lower than the cost of new common equity; therefore, if new common stock had to be issued then the firm’s WACC would increase. The calculated WACC does depend on the size of the capital budget. A firm calculates its retained earnings breakpoint (and any other capital breakpoints for additional debt and preferred). This R/E breakpoint represents the amount of capital raised beyond which new common stock must be issued. Thus, a capital budget smaller than this breakpoint would use the lower cost retained earnings and thus a lower WACC. A capital budget greater than this breakpoint would use the higher cost of new equity and thus a higher WACC. Dividend policy has a significant impact on the WACC. The R/E breakpoint is calculated as the addition to retained earnings divided by the equity fraction. The higher the firm’s dividend payout, the smaller the addition to retained earnings and the lower the R/E breakpoint. (That is, the firm’s WACC will increase at a smaller capital budget.)

10-10If the investment requires $5.9 million, that means that it requires $3.54 million (60%) of common equity and $2.36 million (40%) of debt. In this scenario, the firm would exhaust its $2 million of retained earnings and be forced to raise new stock at a cost of 15%. Needing $2.36 million in debt, the firm could get by raising debt at only 10%. Therefore, its weighted average cost of capital is: WACC = 0.4(10%)(1 – 0.4) + 0.6(15%) = 11.4%.

b.WACC = 0.45(6%) + 0.55(14.40%) = 10.62%.

c.Since the firm’s WACC is 10.62% and each of the projects is equally risky and as risky as the firm’s other assets, MEC should accept Project A. Its rate of return is greater than the firm’s WACC. Project B should not be accepted, since its rate of return is less than MEC’s WACC.

10-13If the firm’s dividend yield is 5% and its stock price is $46.75, the next expected annual dividend can be calculated.

Dividend yield= D1/P0
5%= D1/$46.75
D1= $2.3375.

Next, the firm’s cost of new common stock can be determined from the DCF approach for the cost of equity.

re= D1/[P0(1 – F)] + g

10-15a.Examining the DCF approach to the cost of retained earnings, the expected growth rate can be determined from the cost of common equity, price, and expected dividend. However, first, this problem requires that the formula for WACC be used to determine the cost of common equity.

WACC= wd(rd)(1 – T) + wc(rs)
13.0%= 0.4(10%)(1 – 0.4) + 0.6(rs)
10.6%= 0.6rs
rs= 0.17667 or 17.67%.

From the cost of common equity, the expected growth rate can now be determined.

rs= D1/P0 + g
0.17667= $3/$35 + g
g= 0.090952 or 9.10%.

b.From the formula for the long-run growth rate:
g= (1 – Div. payout ratio)  ROE = (1 – Div. payout ratio)  (NI/Equity)
0.090952= (1 – Div. payout ratio)  ($1,100 million/$6,000 million)
0.090952= (1 – Div. payout ratio)  0.1833333
0.496104= (1 – Div. payout ratio)
Div. payout ratio= 0.503896 or 50.39%.

c.Projects 1 and 2 will be accepted since their rates of return exceed the WACC.

10-19a.If all project decisions are independent, the firm should accept all projects whose returns exceed their risk-adjusted costs of capital. The appropriate costs of capital are summarized below:

RequiredRate ofCost of
A$4 million14.0%12%
B5 million1.512
C3 million9.58
D2 million9.010
E6 million12.512
F5 million12.510
G6 million7.08
H3 million11.58

Therefore, Ziege should accept projects A, C, E, F, and H.

b.With only $13 million to invest in its capital budget, Ziege must choose the best combination of Projects A, C, E, F, and H. Collectively, the projects would account for an investment of $21 million, so naturally not
all these projects may be accepted. Looking at the excess return created by the projects (rate of return minus the cost of capital), we see that the excess returns for Projects A, C, E, F, and H are 2%, 1.5%, 0.5%, 2.5%, and 3.5%. The firm should accept the projects which provide the greatest excess returns. By that rationale, the first project to be eliminated from consideration is Project E. This brings the total investment required down to $15 million, therefore one more project must be eliminated. The next lowest excess return is Project C. Therefore, Ziege’s optimal capital budget consists of Projects A, F, and H, and it amounts to $12 million.

c.Since Projects A, F, and H are already accepted projects, we must adjust the costs of capital for the other two value producing projects (C and E).

RequiredRate ofCost of
C$3 million9.5%8%+1%=9%
E6 million12.512%+1%=13%

If new capital must be issued, Project E ceases to be an acceptable project. On the other hand, Project C’s expected rate of return still exceeds the risk-adjusted cost of capital even after raising additional capital. Hence, Ziege’s new capital budget should consist of Projects A, C, F, and H and requires $15 million of capital, so $3 million of additional capital must be raised.

10-20a.After-tax cost of new debt: rd(1 – T) = 0.09(1 – 0.4) = 5.4%.

Cost of common equity: Calculate g as follows:
With a financial calculator, input N = 9, PV = -3.90, PMT = 0, FV = 7.80, and then solve for I/YR = g = 8.01%  8%.

rs = + g = + 0.08 = + 0.08 = 0.146 = 14.6%.

Skye’s WACC will be 11.22% so long as it finances with debt, preferred stock, and common equity raised as retained earnings. If it expands so rapidly that it uses up all of its retained earnings and must issue new common stock with a cost of 13.83% (average of DCF and CAPM estimates), then its WACC will increase to 11.51%.

Integrated Case

Coleman Technologies Inc.
Cost of Capital

Coleman Technologies is considering a major expansion program that has been proposed by the company’s information technology group. Before proceeding with the expansion, the company must estimate its cost of capital. Assume
that you are an assistant to Jerry Lehman, the financial vice president. Your first task is to estimate Coleman’s cost of capital. Lehman has provided you with the following data, which he believes may be relevant to your task: 1.The firm’s tax rate is 40%.

2.The current price of Coleman’s 12% coupon, semiannual payment, noncallable bonds with 15 years remaining to maturity is $1,153.72. Coleman does not use short-term interest-bearing debt on a permanent basis. New bonds would be privately placed with no flotation cost. 3.The current price of the firm’s 10%, $100 par value, quarterly dividend, perpetual preferred stock is $111.10. 4.Coleman’s common stock is currently selling for $50 per share. Its last dividend (D0) was $4.19, and dividends are expected to grow at a constant rate of 5% in the foreseeable future. Coleman’s beta is 1.2, the yield on T‑bonds is 7%, and the market risk premium is estimated to be 6%. For the bond-yield-plus-risk-premium approach, the firm uses a risk premium of 4%. 5.Coleman’s target capital structure is 30% debt, 10% preferred stock, and 60% common equity. To structure the task somewhat, Lehman has asked you to answer the following questions. A.(1)What sources of capital should be included when you estimate Coleman’s WACC? Answer:[Show S10-1 through S10-3 here.] The WACC is used primarily for making long-term capital investment decisions, i.e., for capital budgeting. Thus, the WACC should include the types of capital used to pay for long-term assets, and this is typically long-term debt, preferred stock (if used), and common stock. Short-term sources of capital consist of (1) spontaneous, noninterest-bearing liabilities such as accounts payable and accrued liabilities and (2) short-term interest-bearing debt, such as notes payable. If the firm uses short-term interest-bearing debt to acquire fixed assets rather than just to finance working capital needs, then the WACC should include a short-term debt component. Noninterest-bearing debt is generally not included in the cost of capital estimate because these funds are netted out when determining investment needs, that is, net operating rather than gross operating working capital is included in capital expenditures. A.(2)Should the component costs be figured on a before-tax or an after-tax basis? Answer:[Show S10-4 here.] Stockholders are concerned primarily with those corporate cash flows that are available for their use, namely, those cash flows available to pay dividends or for reinvestment. Since dividends are paid from and reinvestment is made with after-tax dollars, all cash flow and rate of return calculations should be done on an after-tax basis. A.(3)Should the costs be historical (embedded) costs or new (marginal) costs? Answer:[Show S10-5 and S10-6 here.] In financial management, the cost of capital is used primarily to make decisions that involve raising new capital. Thus, the relevant component costs are today’s marginal costs rather than historical costs. B.What is the market interest rate on Coleman’s debt and its component cost of debt? Answer:[Show S10-7 through S10-9 here.] Coleman’s 12% bond with 15 years to maturity is currently selling for $1,153.72. Thus, its yield to maturity is 10%:

||||  ||
Enter N = 30, PV = -1153.72, PMT = 60, and FV = 1000, and then press the I/YR button to find rd/2 = I/YR = 5.0%. Since this is a semiannual rate, multiply by 2 to find the annual rate, rd = 10%, the pre-tax cost of debt. Since interest is tax deductible, Uncle Sam, in effect, pays part of the cost, and Coleman’s relevant component cost of debt is the after-tax cost: rd(1 – T) = 10.0%(1 – 0.40) = 10.0%(0.60) = 6.0%.

Optional Question
Should you use the nominal cost of debt or the effective annual cost? Answer:Our 10% pre-tax estimate is the nominal cost of debt. Since the firm’s debt has semiannual coupons, its effective annual rate is 10.25%:

(1.05)2 – 1.0 = 1.1025 – 1.0 = 0.1025 = 10.25%.
However, nominal rates are generally used. The reason is that the cost of capital is used in capital budgeting, and capital budgeting cash flows are generally assumed to occur at year-end. Therefore, using nominal rates makes the treatment of the capital budgeting discount rate and cash flows consistent.

C.(1)What is the firm’s cost of preferred stock?
Answer:[Show S10-10 and S10-11 here.] Since the preferred issue is perpetual, its cost is estimated as follows: rp = = = = 0.090 = 9.0%.

Note (1) that since preferred dividends are not tax deductible to the issuer, there is no need for a tax adjustment, and (2) that we could have estimated the effective annual cost of the preferred, but as in the case of debt, the nominal cost is generally used. C.(2)Coleman’s preferred stock is riskier to investors than its debt, yet the preferred’s yield to investors is lower than the yield to maturity on the debt. Does this suggest that you have made a mistake? (Hint: Think about taxes.) Answer:[Show S10-12 and S10-13 here.] Corporate investors own most preferred stock, because 70% of preferred dividends received by corporations are nontaxable. Therefore, preferred often has a lower before-tax yield than the before-tax yield on debt issued by the same company. Note, though, that the after-tax yield to a corporate investor and the after-tax cost to the issuer are higher on preferred stock than on debt. D.(1)Why is there a cost associated with retained earnings? Answer:[Show S10-14 through S10-16 here.] Coleman’s earnings can either be retained and reinvested in the business or paid out as dividends. If earnings are retained, Coleman’s shareholders forgo the opportunity to receive cash and to reinvest it in stocks, bonds, real estate, and the like. Thus, Coleman should earn on its retained earnings at least as much as its stockholders themselves could earn on alternative investments of equivalent risk. Further, the company’s stockholders could invest in Coleman’s own common stock, where they could expect to earn rs. We conclude that retained earnings have an opportunity cost that is equal to rs, the rate of return investors expect on the firm’s common stock. D.(2)What is Coleman’s estimated cost of common equity using the CAPM approach? Answer:[Show S10-17 here.] The CAPM estimate for Coleman’s cost of common equity is 14.2%:

rs= rRF + (rM – rRF)b
= 7.0% + (6.0%)1.2 = 7.0% + 7.2% = 14.2%.
E.What is the estimated cost of common equity using the DCF approach? Answer:[Show S10-18 through S10-20 here.] Since Coleman is a constant growth stock, the constant growth model can be used:

= = =
= + 0.05 = 0.088 + 0.05 = 8.8% + 5.0% = 13.8%.
F.What is the bond-yield-plus-risk-premium estimate for Coleman’s cost of common equity? Answer:[Show S10-21 here.] The bond-yield-plus-risk-premium estimate is 14%: rs = Bond yield + Risk premium = 10.0% + 4.0% = 14.0%.

Note that the risk premium required in this method is difficult to estimate, so this approach only provides a ballpark estimate of rs. It is useful, though, as a check on the DCF and CAPM estimates, which can, under certain circumstances, produce unreasonable estimates. G.What is your final estimate for rs?

Answer:[Show S10-22 here.] The following table summarizes the rs estimates: MethodEstimate
CAPM 14.2%
DCF 13.8
rd + rp 14.0
Average 14.0%
At this point, considerable judgment is required. If a method is deemed to be inferior due to the “quality” of its inputs, then it might be given little weight or even disregarded. In our example, though, the three methods produced relatively close results, so we decided to use the average, 14%, as our estimate for Coleman’s cost of common equity. H.Explain in words why new common stock has a higher cost than retained earnings. Answer:[Show S10-23 here.] The company is raising money in order to make an investment. The money has a cost, and this cost is based primarily on the investors’ required rate of return, considering risk and alternative investment opportunities. So, the new investment must provide a return at least equal to the investors’ opportunity cost. If the company raises capital by selling stock, the company doesn’t receive all of the money that investors contribute. For example, if investors put up $100,000, and if they expect a 15% return on that $100,000, then $15,000 of profits must be generated. But if flotation costs are 20% ($20,000), then the company will receive only $80,000 of the $100,000 investors contribute. That $80,000 must then produce a $15,000 profit, or a $15/$80 = 18.75% rate of return versus a 15% return on equity raised as retained earnings. I.(1)What are two approaches that can be used to adjust for flotation costs? Answer:The first approach is to include the flotation costs as part of the project’s up-front cost. This reduces the project’s estimated return. The second approach is to adjust the cost of capital to include flotation costs. This is most commonly done by incorporating flotation costs in the DCF model. I.(2)Coleman estimates that if it issues new common stock, the flotation cost will be 15%. Coleman incorporates the flotation costs into the DCF approach. What is the estimated cost of newly issued common stock, considering the flotation cost? Answer:[Show S10-24 and S10-25 here.]

re= + g
= + 5.0%
= + 5.0% = 15.35%.
J.What is Coleman’s overall, or weighted average, cost of capital (WACC)? Ignore flotation costs. Answer:[Show S10-26 here.] Coleman’s WACC is 11.1%.
Capital StructureComponent
0.614 8.4
1.0WACC= 11.1%
WACC= wdrd(1 – T) + wprp + wcrs
= 0.3(10%)(0.6) + 0.1(9%) + 0.6(14%)
= 1.8% + 0.9% + 8.4% = 11.1%.
K.What factors influence Coleman’s composite WACC?
Answer:[Show S10-27 here.] There are factors that the firm cannot control and those that they can control that influence WACC. Factors the firm cannot control:
Interest rates
Tax rates
Factors the firm can control:
Capital structure policy
Dividend policy
Investment policy
L.Should the company use the composite WACC as the hurdle rate for each of its projects? Explain. Answer:[Show S10-28 here.] No. The composite WACC reflects the risk of an average project undertaken by the firm. Therefore, the WACC only represents the “hurdle rate” for a typical project with average risk. Different projects have different risks. The project’s WACC should be adjusted to reflect the project’s risk.
