Find the effective monthly rate, effective annual rate and the effective daily rate. Assume that there are 365 days in a year.

All answers are given in the same order:

### r_\text{eff monthly} , r_\text{eff yearly} , r_\text{eff daily} ###

(a) 0.0072, 0.09, 0.0002.

(b) 0.0139, 0.18, 0.0005.

(c) 0.0139, 6.2876, 0.0055.

(d) 0.015, 0.1956, 0.0005.

(e) 0.015, 0.1956, 0.006.

Question 63  bond pricing, NPV, market efficiency

The theory of fixed interest bond pricing is an application of the theory of Net Present Value (NPV). Also, a 'fairly priced' asset is not over- or under-priced. Buying or selling a fairly priced asset has an NPV of zero.

Considering this, which of the following statements is NOT correct?

(a) The internal rate of return (IRR) of buying a bond is equal to the bond's yield.

(b) The present value of a fairly priced bond's coupons and face value is equal to its price.

(c) If the required return of a bond falls, its price will fall.

(d) Fairly priced discount bonds' yield is more than the coupon rate, price is less than face value, and the NPV of buying them is zero.

(e) The NPV of buying a fairly priced bond is zero.

Question 137  NPV, Annuity

The following cash flows are expected:

• 10 yearly payments of $60, with the first payment in 3 years from now (first payment at t=3 and last at t=12).
• 1 payment of $400 in 5 years and 6 months (t=5.5) from now.

What is the NPV of the cash flows if the discount rate is 10% given as an effective annual rate?

(a) $513.80

(b) $525.36

(c) $541.50

(d) $605.48

(e) $704.69

Question 157  bill pricing, simple interest rate, no explanation

A 90-day Bank Accepted Bill has a face value of $1,000,000. The interest rate is 6% pa and there are 365 days in the year. What is its price?

(a) $13,369,963.37

(b) $6,400,000.00

(c) $985,735.05

(d) $985,421.17

(e) $156,250.00

Question 271  CAPM, option, risk, systematic risk, systematic and idiosyncratic risk

All things remaining equal, according to the capital asset pricing model, if the systematic variance of an asset increases, its required return will increase and its price will decrease.
If the idiosyncratic variance of an asset increases, its price will be unchanged.

What is the relationship between the price of a call or put option and the total, systematic and idiosyncratic variance of the underlying asset that the option is based on? Select the most correct answer.

Call and put option prices increase when the:

(a) Systematic variance of the underlying asset increases.

(b) Idiosyncratic variance of the underlying asset increases.

(c) Systematic, idiosyncratic or total variance of the underlying asset increases.

(d) Systematic variance of the underlying asset decreases.

(e) Systematic, idiosyncratic or total variance of the underlying asset decreases.

Question 310  foreign exchange rate

Is it possible for all countries' exchange rates to appreciate by 5% in the same year, including the USD? or ?

Question 369  interest tax shield, CFFA

One formula for calculating a levered firm's free cash flow (FFCF, or CFFA) is to use earnings before interest and tax (EBIT).

###\begin{aligned} FFCF &= (EBIT)(1-t_c) + Depr - CapEx -\Delta NWC + IntExp.t_c \\ &= (Rev - COGS - Depr - FC)(1-t_c) + Depr - CapEx -\Delta NWC + IntExp.t_c \\ \end{aligned} \\###

Does this annual FFCF or the annual interest tax shield?

Question 388  real option, option

A moped is a bicycle with pedals and a little motor that can be switched on to assist the rider. Mopeds are useful for quick transport using the motor, and for physical exercise when using the pedals unassisted. This offers the rider:

(a) An expansion option.

(b) An abandonment option.

(c) A timing (or delaying) option.

(d) A production (or switching) option.

(e) Lots of options to exercise if they're out-of-money and have no fuel.

Question 642  future, no explanation

Which of the below formulas gives the payoff at maturity ##(f_T)## from being short a future? Let the underlying asset price at maturity be ##S_T## and the locked-in futures price be ##K_T##.

(a) ##f_{SF,T}=S_T+K_T##

(b) ##f_{SF,T}=-S_T-K_T##

(c) ##f_{SF,T}=S_T-K_T##

(d) ##f_{SF,T}=K_T-S_T##

(e) ##f_{SF,T}=S_T##

Question 761  NPV, annuity due, no explanation

The phone company Optus have 2 mobile service plans on offer which both have the same amount of phone call, text message and internet data credit. Both plans have a contract length of 24 months and the monthly cost is payable in advance. The only difference between the two plans is that one is a:

• 'Bring Your Own' (BYO) mobile service plan, costing $80 per month. There is no phone included in this plan. The other plan is a:
• 'Bundled' mobile service plan that comes with the latest smart phone, costing $100 per month. This plan includes the latest smart phone.

Neither plan has any additional payments at the start or end. Assume that the discount rate is 1% per month given as an effective monthly rate.

The only difference between the plans is the phone, so what is the implied cost of the phone as a present value? Given that the latest smart phone actually costs $600 to purchase outright from another retailer, should you commit to the BYO plan or the bundled plan?

(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.
