Which of the following statements best describes your situation?
Question 432 option, option intrinsic value, no explanation
An American style call option with a strike price of ##K## dollars will mature in ##T## years. The underlying asset has a price of ##S## dollars.
What is an expression for the current intrinsic value in dollars from owning (being long) the American style call option? Note that the intrinsic value of an option does not subtract the premium paid to buy the option.
Question 433 Merton model of corporate debt, real option, option, no explanation
A risky firm will last for one period only (t=0 to 1), then it will be liquidated. So it's assets will be sold and the debt holders and equity holders will be paid out in that order. The firm has the following quantities:
##V## = Market value of assets.
##E## = Market value of (levered) equity.
##D## = Market value of zero coupon bonds.
##F_1## = Total face value of zero coupon bonds which is promised to be paid in one year.
What is the payoff to equity holders at maturity, assuming that they keep their shares until maturity?
Question 759 time calculation, fully amortising loan, no explanation
Five years ago you entered into a fully amortising home loan with a principal of $500,000, an interest rate of 4.5% pa compounding monthly with a term of 25 years.
Then interest rates suddenly fall to 3% pa (t=0), but you continue to pay the same monthly home loan payments as you did before. How long will it now take to pay off your home loan? Measure the time taken to pay off the home loan from the current time which is 5 years after the home loan was first entered into.
Assume that the lower interest rate was given to you immediately after the loan repayment at the end of year 5, which was the 60th payment since the loan was granted. Also assume that rates were and are expected to remain constant.
Question 770 expected and historical returns, income and capital returns, coupon rate, bond pricing
Which of the following statements is NOT correct? Assume that all events are a surprise and that all other things remain equal. So for example, don't assume that just because a company's dividends and profit rise that its required return will also rise, assume the required return stays the same.

| Risk free cont. comp. rate (pa) | ##r## | 0.05 |
| Standard deviation of the stock's cont. comp. returns (pa) | ##\sigma## | 0.3 |
| Option maturity (years) | ##T## | 1 |
| Call option price ($) | ##c_0## | 3.939488 |

| ##N[d_2]## | ##N[d_2]## | 0.643514 |
| Gamma | ##\Gamma## | 0.053199 |
| Theta ($/year) | ##\Theta = \partial c / \partial T## | 1.566433 |
The market's expected total return is 10% pa and the risk free rate is 5% pa, both given as effective annual rates.
A stock has a beta of 0.7.

Question 959 negative gearing, leverage, capital structure, interest tax shield, real estate
Last year, two friends Gear and Nogear invested in residential apartments. Each invested $1 million of their own money (their net wealth).
Apartments cost $1,000,000 last year and they earned net rents of $30,000 pa over the last year. Net rents are calculated as rent revenues less the costs of renting such as property maintenance, land tax and council rates. However, interest expense and personal income taxes are not deducted from net rents.
Gear and Nogear funded their purchases in different ways:
- Gear used $1,000,000 of her own money and borrowed $4,000,000 from the bank in the form of an interest-only loan with an interest rate of 5% pa to buy 5 apartments.
- Nogear used $1,000,000 of his own money to buy one apartment. He has no mortgage loan on his property.
Both Gear and Nogear also work in high-paying jobs and are subject personal marginal tax rates of 45%.
