Q1.

Unlevered Beta and CAPM (Using Business Risk Only)

A firm has levered beta = 1.68, D/E = 0.34, tax rate = 29%.
What is its unlevered (asset) beta? (Use the standard formula removing leverage.)

If the risk-free rate is 2% and the expected market return is 9%, what is the expected return using CAPM with the unlevered beta?

Q2.

WACC and Value Creation Threshold

A firm has Equity = $330m, Debt = $188m, Re = 15.1%, Rd = 8%, Tax = 30%.
Compute the WACC (after tax).

Suppose a project in this firm has expected return = 14.4%.
By how many percentage points does the project’s return exceed the WACC? (This gap signals value creation if positive.)

Q3.

Comparable Company Method: Unlever and Relever Beta

A comparable firm has β = 1.19, D/E = 0.46, tax = 23%.
(a) Compute the unlevered beta for the business.

(b) Your target firm will finance the project at D/E = 0.67. Compute the relevered beta to be used in CAPM.

Q4.

Portfolio Beta and Cost of Capital

A two-asset portfolio invests 54% in Asset A (β = 1.09) and 46% in Asset B (β = 0.9).
Compute the portfolio beta.

With Rf = 3.2% and Rm = 9.2%, compute the portfolio’s cost of capital via CAPM.

Q5.

Relevering Beta – Aurora Technologies

Aurora Technologies has an asset beta of 0.82.
Its debt-to-equity ratio is 1.3, and the corporate tax rate is 30.93%.

Q6.

Cost of Debt Capital – CAPM and Default Approach

Q7.

Portfolio Beta with Multiple Divisions

An institutional investor holds two divisions of Aurora Technologies:
- Division A weight = 59.94%, beta = 1.29
- Division B weight = 40.06%, beta = 0.77

Q8.

After-tax Cost of Debt

Aurora Technologies issues new bonds with a yield to maturity of 5.8%.
The corporate tax rate is 23.98%.

Q9.

Project-specific Discount Rate

Aurora Technologies considers investing in a high-risk digital platform.
- Risk-free rate = 2.98%
- Market risk premium = 4.81%
- Project beta = 1.43
