Question 65  annuity with growth, needs refinement

Which of the below formulas gives the present value of an annuity with growth?

(a) ##\dfrac{C_1}{r-g}\left(1-\dfrac{1}{(1+r)^T}\right)##

(b) ##\dfrac{C_1(1+g)^T}{r-g}\left(1-\dfrac{1}{(1+r)^T}\right)##

(c) ##\dfrac{C_1}{r-g}\left(1-\dfrac{1+g}{(1+r)^T}\right)##

(d) ##\dfrac{C_1}{r-g}\left(1-\left(\dfrac{1+g}{1+r}\right)^T \right)##

(e) ##\dfrac{C_1(1+g)}{r-g}\left(1-\dfrac{1}{(1+r)^T}\right)##

Hint: The equation of a perpetuity without growth is: ###V_\text{0, perp without growth} = \frac{C_\text{1}}{r}###

The formula for the present value of an annuity without growth is derived from the formula for a perpetuity without growth.

The idea is than an annuity with T payments from t=1 to T inclusive is equivalent to a perpetuity starting at t=1 with fixed positive cash flows, plus a perpetuity starting T periods later (t=T+1) with fixed negative cash flows. The positive and negative cash flows after time period T cancel each other out, leaving the positive cash flows between t=1 to T, which is the annuity.

###\begin{aligned} V_\text{0, annuity} &= V_\text{0, perp without growth from t=1} - V_\text{0, perp without growth from t=T+1} \\ &= \dfrac{C_\text{1}}{r} - \dfrac{ \left( \dfrac{C_\text{T+1}}{r} \right) }{(1+r)^T} \\ &= \dfrac{C_\text{1}}{r} - \dfrac{ \left( \dfrac{C_\text{1}}{r} \right) }{(1+r)^T} \\ &= \dfrac{C_\text{1}}{r}\left(1 - \dfrac{1}{(1+r)^T}\right) \\ \end{aligned}###

The equation of a perpetuity with growth is:

###V_\text{0, perp with growth} = \dfrac{C_\text{1}}{r-g}###

Question 180  equivalent annual cash flow, inflation, real and nominal returns and cash flows

Details of two different types of light bulbs are given below:

• Low-energy light bulbs cost $3.50, have a life of nine years, and use about $1.60 of electricity a year, paid at the end of each year.
• Conventional light bulbs cost only $0.50, but last only about a year and use about $6.60 of energy a year, paid at the end of each year.

The real discount rate is 5%, given as an effective annual rate. Assume that all cash flows are real. The inflation rate is 3% given as an effective annual rate.

Find the Equivalent Annual Cost (EAC) of the low-energy and conventional light bulbs. The below choices are listed in that order.

(a) 1.4873, 6.7857

(b) 1.6525, 6.7857

(c) 2.1415, 7.1250

(d) 14.8725, 6.7857

(e) 2.0924, 7.1250

Question 277  derivative terminology, future

The 'initial margin', also known as the performance bond in a futures contract, is paid at the start when the futures contract is agreed to. or ?

Question 384  option, real option

Which of the following is the least useful method or model to calculate the value of a real option in a project?

(a) Project value with the option less project value without the option.

(b) No-arbitrage binomial option pricing model.

(d) Gordon growth model.

(e) Black-Sholes option pricing model.

Question 404  income and capital returns, real estate

One and a half years ago Frank bought a house for $600,000. Now it's worth only $500,000, based on recent similar sales in the area.

The expected total return on Frank's residential property is 7% pa.

He rents his house out for $1,600 per month, paid in advance. Every 12 months he plans to increase the rental payments.

The present value of 12 months of rental payments is $18,617.27.

The future value of 12 months of rental payments one year in the future is $19,920.48.

What is the expected annual rental yield of the property? Ignore the costs of renting such as maintenance, real estate agent fees and so on.

(a) 3.1029%

(b) 3.3201%

(c) 3.7235%

(d) 3.9841%

(e) 7%

Question 481  Annuity

This annuity formula ##\dfrac{C_1}{r}\left(1-\dfrac{1}{(1+r)^3} \right)## is equivalent to which of the following formulas? Note the 3.

In the below formulas, ##C_t## is a cash flow at time t. All of the cash flows are equal, but paid at different times.

(a) ##C_0+C_1+C_2+C_3##

(b) ##\dfrac{C_0+C_1+C_2+C_3}{(1+r)^3} ##

(c) ##C_0+\dfrac{C_1}{(1+r)^1} +\dfrac{C_2}{(1+r)^2} + \dfrac{C_3}{(1+r)^3} ##

(d) ##\dfrac{C_1}{(1+r)^1} +\dfrac{C_2}{(1+r)^2} + \dfrac{C_3}{(1+r)^3} ##

(e) ##\dfrac{C_1}{(1+r)^1} + \dfrac{C_2}{(1+r)^2} ##

Question 727  inflation, real and nominal returns and cash flows

The Australian Federal Government lends money to domestic students to pay for their university education. This is known as the Higher Education Contribution Scheme (HECS). The nominal interest rate on the HECS loan is set equal to the consumer price index (CPI) inflation rate. The interest is capitalised every year, which means that the interest is added to the principal. The interest and principal does not need to be repaid by students until they finish study and begin working.

Which of the following statements about HECS loans is NOT correct?

(a) The real interest rate is zero.

(b) The nominal amount owing on the loan will increase at the inflation rate over time, if there are no extra payments or borrowings.

(c) The real amount owing on the loan in today's money will remain the same over time, if there are no extra payments or borrowings.

(d) The interest rate on the HECS loan advantages rich domestic students because they are able to pay off their debt sooner and avoid paying as much HECS interest.

(e) The interest rate on the HECS loan advantages all domestic students because the alternative of borrowing from the bank to pay for education would usually attract a higher interest rate.

Question 787  fixed for floating interest rate swap, intermediated swap

The below table summarises the borrowing costs confronting two companies A and B.

Bond Market Yields
	Fixed Yield to Maturity (%pa)	Floating Yield (%pa)
Firm A	2	L - 0.1
Firm B	2.5	L

 

Firm A wishes to borrow at a floating rate and Firm B wishes to borrow at a fixed rate. Design an intermediated swap (which means there will actually be two swaps) that nets a bank 0.15% and grants the remaining swap benefits to Firm A only. Which of the following statements about the swap is NOT correct?

(a) Firm A is less risky than Firm B. Firm A would have a higher credit rating.

(b) Firm A has the absolute advantage issuing bonds in both the fixed and floating coupon bond markets.

(c) Firm A has a comparative advantage issuing bonds in the floating coupon bond market.

(d) The net benefit from the swap available to Firm A is 0.25%.

(e) The swap rate between Firm B and the Bank would be 2.5% pa.

Question 950  future, backwardation

Question 953  option, out of the money option

If a call option is out-of-the-money, then the spot price (##S_0##) is than, than or to the call option's strike price (##K_T##)?
