Explanation:
In the Merton model:
Assumption I is CORRECT: An increase in the risk-free rate will increase the firm's equity value. This is because equity is valued as a call option on the firm's assets, and the value of a call option increases with higher risk-free rates (due to the reduced present value of the strike price).
Assumption II is INCORRECT: An increase in the risk-free rate does NOT affect the estimated physical default probability. The physical default probability (PD) is calculated using the actual expected return on assets (8% in this case), not the risk-free rate. The risk-free rate is only used in the risk-neutral valuation of equity, not in the calculation of the physical distance to default.
Key points:
Therefore, only Assumption I is correct.

Analyst Greg is employing the Merton model to both value a firm's equity and estimate a physical default probability. He has collected the following information:
$10 million; e.g., face value of short-term debt is $10 million.$12.75 million with an expected return of 8% per annum with continuous compoundingHis exercise includes two components: one, valuation of the firm's equity market value by treating equity as a call option on the firm's assets; two, estimate of default probability by calculation of a forward distance to default. Greg makes two assumptions: I. An increase in the risk-free rate will increase an estimate of the firm's current equity market value, and II. An increase in the risk-free rate will decrease the estimated default probability.
Which of Greg's two assumptions is correct?
A
Neither
B
I only
C
II only
D
Both
