(a) Effective rates compound once over their time period. So an effective monthly rate compounds once per month.

(b) APR's compound more than once per year. So an APR compounding monthly compounds 12 times per year. The exception is an APR that compounds annually (once per year) which is the same thing as an effective annual rate.

(c) To convert an effective rate to an APR, multiply the effective rate by the number of time periods in one year. So an effective monthly rate multiplied by 12 is equal to an APR compounding monthly.

(d) To convert an APR compounding monthly to an effective monthly rate, divide the APR by the number of months in one year (12).

(e) To convert an APR compounding monthly to an effective weekly rate, divide the APR by the number of weeks in one year (approximately 52).

In a takeover deal where the offer is 100% cash, the merged firm's number of shares will be equal to the acquirer firm's original number of shares. or ?

Two put options are exactly the same, but one matures in one year and the other matures in two years. Which option would you expect to have the higher price, the option which matures or , or should they have the price?

(a) A bullet loan has no interest payments but it does have a face value. Therefore it's a discount loan.

(b) A fully amortising loan has interest payments but does not have a face value. Therefore it's a premium loan.

(c) An interest only loan has interest payments and its price and face value are equal. Therefore it's a par loan.

(d) A zero coupon bond has no coupon payments but it does have a face value. Therefore it's a premium bond.

(e) A balloon loan has interest payments and its face value is more than its price. Therefore it's a discount loan.

(a) -9,   15.65

(b) -9,   14.3

(a) Systematic risk increases.

(b) Idiosyncratic risk increases.

(c) Total risk increases.

(d) Systematic risk decreases.

(e) Idiosyncratic risk decreases.

(a) Arithmetic average gross discrete return is ##\text{AAGDR}_{0\rightarrow T} = \dfrac{\text{GDR}_{0 \rightarrow 1}+\text{GDR}_{1\rightarrow 2}+...+\text{GDR}_{T-1 \rightarrow T}}{T}##

(b) Geometric average gross discrete return is ##\text{GAGDR}_{0\rightarrow T} = \dfrac{\text{GDR}_{0 \rightarrow 1} . \text{GDR}_{1\rightarrow 2} ... \text{GDR}_{T-1 \rightarrow T}}{T}##

(c) The geometric average gross discrete return can be quickly found using the first ##(P_0)## and last ##(P_T)## prices. ##\text{GAGDR}_{0\rightarrow T} = \left( \dfrac{P_T}{P_0} \right)^{1/T}##

(d) The arithmetic average is always bigger than or equal to the geometric average, ##\text{AAGDR} \ge \text{GAGDR}##.

(e) The arithmetic and geometric averages of returns will be equal if the variance of the stock's returns is zero.

(a) $480, so the bundled plan is best.

(b) $462.94, so the BYO plan is best.

(c) $429.12, so the bundled plan is best.

(d) $424.87, so the BYO plan is best.

(e) $420.66, so the bundled plan is best.

(a) ##N[d_1]##

(b) ##N[d_2]##

(c) ##−N[−d_1]##

(d) ##−N[−d_2]##

(e) ##N[−d_2]##

(a) Options are always worth more than or equal to equivalent European-style options.

(b) Call options on dividend-paying stocks should sometimes be exercised just before the dividend.

(c) Put options on dividend-paying stocks should sometimes be exercised just after the dividend.

(d) Call options should be exercised now if the intrinsic option value ##(S-K)## is greater than the expected present value of the option’s future payoffs.

(e) Put options should be exercised now if the intrinsic option value ##(K-S)## is less than the expected present value of the option’s future payoffs.
