Final answer:
According to MM Proposition I, the stock price for Aussie Ltd should be equal to Kiwi Ltd, since capital structure does not influence firm value in perfect capital markets with no taxes. Investing in Aussie Ltd, which is undervalued at $10 million, provides an opportunity for arbitrage. To exploit this opportunity, one would purchase shares in Aussie Ltd and short-sell shares in Kiwi Ltd to make a riskless profit.
Step-by-step explanation:
The question refers to two firms, Kiwi Ltd and Aussie Ltd, with different capital structures, and discusses valuation according to Miller and Modigliani's Proposition I (MM Proposition 1). Since both firms have identical cash flows and we're assuming perfect capital markets with no taxes, per MM Proposition 1, the market value of both firms should be the same because the value of the firm is not affected by its capital structure, only by its assets and earnings.
A) The stock price for Aussie Ltd, when considering MM Proposition 1, would remain the same as that of Kiwi Ltd because the capital structure does not affect firm value. Thus, Aussie Ltd's total firm value would be 1 million shares at $24 each, totaling $24 million, minus the $12 million debt, resulting in $12 million equity value. Since the equity of Aussie Ltd is valued at $10 million, which is lower than the value calculated using MM Proposition 1 ($12 million), there is an arbitrage opportunity.
B) You would invest in Aussie Ltd if the equity is undervalued at $10 million since it indicates that the shares are trading at a discount compared to their theoretical value in these perfect market conditions.
C) To execute a riskless arbitrage for a 10% ownership stake in Aussie Ltd, you could purchase 10% of Aussie Ltd's undervalued equity at $10 million, which would cost you $1 million. Simultaneously, you could short-sell 10% of Kiwi Ltd's overvalued equity for $2.4 million. With no taxes and the ability to borrow at the same interest rate, you could use the proceeds from the short sale to pay for the purchase and also repay any borrowed amount. The profit from this arbitrage would be the difference between the two values.
Optimal Capital Structure in MM Perfect Capital Markets with No Taxes:
In perfect capital markets with no taxes, as per Modigliani and Miller, the optimal capital structure is irrelevant because the firm's value is determined entirely by its assets and operation, not by the mixture of debt and equity it employs.
