Cost of Capital and capital structure Flashcards
What is the cost of equity?
The cost of equity is the return investors expect to achieve on their shares in a company.
The rate of return an investor requires is based on the level of risk associated with the investment.
Equity shareholders are the last investors to be paid out of company profits, as well as the last to be paid on the winding up of a company.
Equity investors face the greatest risk of all investors and therefore demand a higher rate of return to justify the risk taken.
There are two methods of determining the cost of equity:
- the capital asset pricing model
- the dividend valuation model
Capital asset pricing model?
Capital asset pricing model
The capital asset pricing model (CAPM) was developed by Sharpe (1964) and Lintner (1965) as a means to measure the
cost of equity.
The model studies and establishes an equilibrium relationship between the expected returns from each security and its associated risks.
It can be used to assess risk in individual company shares or a portfolio of securities.
The cost of equity capital obtained under CAPM is called the risk-adjusted discount rate (RADR).
Once the market portfolio has been established, the required rate of return for any security can be calculated using this model provided the beta factor (see page 210 of book) is known.
Risk-adjusted discount rate
Risk-adjusted discount rate
The risk inherent in a project depends on the type of activity involved.
Higher risk does not necessarily make a project unattractive.
The RADR is the rate used to discount a risky asset or investment such as real estate.
It represents the required periodical returns by investors to compensate for the higher risk involved.
The higher the risk involved in the project, the higher the discount rate.
The cash flows from riskier assets will be discounted at a higher rate. This adjusted discount rate is typically referred to as expected rate of return. It forms the basis for CAPM.
The RADR is based on the risk-free rate (RFR) (such as a short-term interest rate from government securities or a fixed
deposit rate) and a risk premium for the riskier assets.
What is the RADR based on?
The RADR is based on the risk-free rate (RFR) (such as a short-term interest rate from government securities or a fixed deposit rate) and a risk premium for the riskier assets.
RADR = RFR + risk premium
Where:
RADR = Risk-adjusted discount rate
RFR = Risk-free rate
Unsystematic risks?
Unsystematic risks:
Are risk factors specific to a particular company or industry which can be eliminated or diversified away in a large portfolio of shares. These risks are not impacted by political and economic factors.
Examples include:
weak labour relations, adverse press reports and strikes.
These are different for different companies; they might even cancel each other out in some circumstances.
Studies have shown that if the portfolio consists of 15 to 20 shares, then most of the unsystematic risk tends to be diversified.
Systematic risk (or market risk) ?
Systematic risk (or market risk)
Relates to the markets and the economy.
It is largely caused by macroeconomic factors and affects all the shares in the market.
It is unavoidable and cannot be diversified.
An example may be an economic recession affecting both the markets and the economy of the country.
The level to which each share will be affected will differ, although it is known that all shares will be affected.
It should be noted that, even in a severe recession like that caused by the Covid-19 pandemic, there might be a small number of companies doing well.
This is usually for a specific reason that affects a niche market.
A good example relating to the Covid-19 pandemic would be companies providing remote working solutions, such as Zoom or Cisco, due to the large increase in people working from home.
Systematic risk is different in different industries….Explain?
The degree of systematic risk is different in different industries. For instance, the food retailing sector faces lower systematic risk in comparison to the hospitality sector, as food is a necessity.
Irrespective of a recession, people will still
require their daily essentials.
It is possible for an investor to select shares with a low systematic risk. Thus, investors
need to select shares that will provide returns over and above its risk-free rate of return.
The CAPM suggests that investors can eliminate the unsystematic risk and thus reduce the overall risk by choosing an
optimal portfolio.
It assumes that investors will behave rationally.
Measuring systematic risk and calculating RADR.
Measuring systematic risk and calculating RADR.
The CAPM assumes that unsystematic risk can be diversified and eliminated, whereas systematic risk cannot be eliminated and diversified.
Investors will expect a higher return from shares with a higher systematic risk.
Therefore, it is important to measure systematic risk.
The steps involved in CAPM are:
- measuring the systematic risk
- linking the systematic risk with the required rate of return

Linking ß with required returns: the security market line
RADR = RFR + ß (RM – RFR)
Where:
- RFR = Risk-free rate
- RM = return on stock market portfolio
- ß = risk premium statistically derived
*RM – RFR = market risk premium (the expected return on the market minus the risk-free rate).
Worked example 12.2 page 211 in linking ß with the required return
Nayu plc has a ß of 1.40 and the market return is 14%.
The RFR is 10%. Calculate the cost of equity
based on the CAPM.
Solution:
RADR = RFR + ß (RM – RFR)
RADR = 10 + 1.4(14 – 10) = 10 + 5.6 = 15.6%
The cost of equity of Nayu plc is 15.6%
Assumptions of CAPM?
Assumptions of CAMP
- Investors are rational and possess full knowledge about the market.
- Investors expect greater returns for taking greater risks.
- It is possible for an investor to diversify the unsystematic risk by actively managing the portfolio.
- Borrowing and lending rates are equal.
- There are no transaction costs.
6 There is no taxation and no inflation
Criticisms of CAPM
Criticisms
- Research has shown that the linearity of the SML has been lost with changes of gradient at different levels of ß during some periods.
- There are practical difficulties in deriving the systematic risk and the ß of any company as trading on the stock
market is subject to numerous factors. - Companies with more than one division and company channel might have different systematic risks for each division – yet ß is derived on the basis of a single share price.
- The CAPM is a one-year model and is relevant for a year only.
Cost of equity using the dividend valuation model
Cost of equity using the dividend valuation model
The dividend valuation model (or dividend growth model) states that the value of the company/share is the present value of the expected future dividends discounted at the shareholders’ required rate of return.
Cost of equity using the dividend valuation model calculation?
Assuming a constant growth rate in dividends:
P = D0 (1 + g) ÷ (Ke – g)
Where:
- P = current share price
- D0 = current level of dividend
- g = estimated growth rate in dividends
If we need to derive Ke, the formula can be rearranged to:
Ke = [D0 (1 + g) ÷ P0] + g
D0 (1 + g) is the dividend at the end of the year (D1).
Worked example 12.3 page 212 of book
Worked example 12.3
Nehi plc has £1 equity shares in issue with a market value of £1.20 per share.
A dividend of 15p per share has just been paid.
Estimate the cost of equity required by the equity shareholders if the rate of growth in dividends is 6%.
Solution
Ke = [D0 (1+g) ÷ P] + g
Ke = [15(1 + 0.06) ÷ 120] + 0.06 = (15.9 ÷ 120) + 0.06 = 0.1925 = 19.25%
The cost of equity of Nehi plc is 19.25%
