Section B - Case 2: NeuroLink Prosthetics

Scenario: NeuroLink Prosthetics is a MedTech firm. It has 10 million ordinary shares in issue, currently trading at $4.50 per share. The company's equity beta is 1.2. The risk-free rate of return is 4% and the expected return on the market portfolio is 10%. NeuroLink also has $15 million (nominal value) of 6% redeemable bonds, currently trading at $95 per $100 nominal, redeemable at par in 5 years. The corporate tax rate is 25%.

Question: Using the Capital Asset Pricing Model (CAPM), what is NeuroLink's cost of equity?

Answer options:

A.

7.2%

B.

11.2%

C.

16.0%

D.

12.0%

How to approach this question

Apply the CAPM formula: Ke = Risk-free rate + Beta * (Market Return - Risk-free rate). Note that the 'expected return on the market' is Rm, not the market risk premium.

Full Answer

B.11.2%✓ Correct
The Capital Asset Pricing Model (CAPM) calculates the required return on equity based on systematic risk. Formula: Ke = Rf + β(Rm - Rf) Where Rf = 4%, β = 1.2, Rm = 10%. Ke = 4% + 1.2 * (10% - 4%) Ke = 4% + 1.2 * 6% Ke = 4% + 7.2% = 11.2%.

Common mistakes

Treating the 10% market return as the market risk premium (Rm - Rf). If the question says 'market risk premium is 10%', you don't subtract the risk-free rate. Here it says 'expected return on the market', so you must subtract it.
