In what sense is the cost of capital an opportunity cost? An opportunity cost to whom? And, Is it possible that there could be sources of financing that have a zero cost?
In: Finance
The Cost of Capital: Cost of Retained Earnings
The cost of common equity is based on the rate of return that investors require on the company's common stock. New common equity is raised in two ways: (1) by retaining some of the current year's earnings and (2) by issuing new common stock. Equity raised by issuing stock has a(n)
cost, re, than equity raised from retained earnings, rs, due to flotation costs required to sell new common stock. Some argue that retained earnings should be "free" because they represent money that is left over after dividends are paid. While it is true that no direct costs are associated with retained earnings, this capital still has a cost, a(n)
cost. The firm's after-tax earnings belong to its stockholders, and these earnings serve to compensate them for the use of their capital. The earnings can either be paid out in the form of dividends to stockholders who could have invested this money in alternative investments or retained for reinvestment in the firm. Therefore, the firm needs to earn at least as much on any earnings retained as the stockholders could earn on alternative investments of comparable risk. If the firm cannot invest retained earnings to earn at least rs, it should pay those funds to its stockholders and let them invest directly in stocks or other assets that will provide that return. There are three procedures that can be used to estimate the cost of retained earnings: the Capital Asset Pricing Model (CAPM), the Bond-Yield-Plus-Risk-Premium approach, and the Discounted Cash Flow (DCF) approach.
CAPM
The firm's cost of retained earnings can be estimated using the
CAPM equation as follows:
rs = rRF + (RPM)bi =
rRF + (rM -
rRF)bi
The CAPM estimate of rs is equal to the risk-free rate,
rRF, plus a risk premium that is equal to the risk
premium on an average stock, (rM - rRF),
scaled up or down to reflect the particular stock's risk as
measured by its beta coefficient, bi. This model assumes
that a firm's stockholders are
diversified, but if they are diversified, then the firm's true investment risk would not be measured by and the CAPM estimate would
the correct value of rs.
Bond Yield Plus Risk Premium
If reliable inputs for the CAPM are not available as would be true for a closely held company, analysts often use a subjective procedure to estimate the cost of equity. Empirical studies suggest that the risk premium on a firm's stock over its own bonds generally ranges from 3 to 5 percentage points. The equation is shown as: rs = Bond yield + Risk premium. Note that this risk premium is
the risk premium given in the CAPM. This method doesn't produce a precise cost of equity, but does provide a ballpark estimate.
DCF
The DCF approach for estimated the cost of retained earnings,
rs, is given as follows:
Investors expect to receive a dividend yield, , plus a capital
gain, g, for a total expected return. In
, this expected return is also equal to the required return. It's easy to calculate the dividend yield; but because stock prices fluctuate, the yield varies from day to day, which leads to fluctuations in the DCF cost of equity. Also, it is difficult to determine the proper growth especially if past growth rates are not expected to continue in the future. However, we can use growth rates as projected by security analysts, who regularly forecast growth rates of earnings and dividends.
Which method should be used to estimate rs? If management has confidence in one method, it would probably use that method's estimate. Otherwise, it might use some weighted average of the three methods. Judgment is important and comes into play here, as is true for most decisions in finance.
Quantitative Problem: Barton Industries estimates its cost of common equity by using three approaches: the CAPM, the bond-yield-plus-risk-premium approach, and the DCF model. Barton expects next year's annual dividend, D1, to be $1.50 and it expects dividends to grow at a constant rate g = 3.1%. The firm's current common stock price, P0, is $28.00. The current risk-free rate, rRF, = 4%; the market risk premium, RPM, = 5.3%, and the firm's stock has a current beta, b, = 1.2. Assume that the firm's cost of debt, rd, is 6.11%. The firm uses a 3.3% risk premium when arriving at a ballpark estimate of its cost of equity using the bond-yield-plus-risk-premium approach. What is the firm's cost of equity using each of these three approaches? Round your answers to 2 decimal places.
| CAPM cost of equity: | % |
| Bond yield plus risk premium: | % |
| DCF cost of equity: | % |

Sixteen-year-old Michelle Portman was out driving at night near
Sandusky, Ohio with her friend Katie Webster in the front passenger
seat. They came to a railroad crossing with multiple tracks, where
the mechanical arm had descended and warning bells were sounding. A
Conrail train had suffered mechanical problems and was stopped 200
hundred feet from the crossing, where it had been stalled for close
to an hour. Michelle and Katie saw several cars ahead of them go
around the barrier and cross the tracks, despite the fact that
Ohio’s vehicle and traffic laws prohibited this practice. Michelle
had to decide whether she would do the same.
Long before Michelle made her decision, the train’s engineer (a
Conrail employee) had seen the heavy Saturday night traffic
crossing the tracks and realized the danger. The conductor and
brakeman also understood the peril, but rather than posting a
flagman who could have stopped traffic when a train approached,
they walked to the far end of their train to repair the mechanical
problem. A police officer had come upon the scene, told his
dispatcher to notify the train’s parent company Conrail of the
situation, and left.
Michelle made the decision to cross the tracks. She slowly followed
the cars ahead of her. Seconds later, both girls were dead. A
freight train traveling 60 miles per hour struck the vehicle
broadside, killing Michelle and Katie instantly.
Michelle’s mother sued Conrail for negligence. The company argued
that it was Michelle’s decision, one that violated Ohio traffic
laws, which led to her death. Ohio is a comparative negligence
state. Discuss both the plaintiff’s claim and Conrail’s defense.
What verdict will result?
