Subject:AccountingPrice:9.82 Bought3
Assume that you just won the government vaccination lottery. Your prize can be taken either in the form of $100,000 at the end of each of the next 20 years (i.e., $2 million over 20 years) or as a lump sum of $1,000,000 paid immediately.
(a) If you expect to invest $100,000 annually that earns 6% annually on your investments over the next 20 years, calculate the current value of future payments from an annuity. Explain how you would use time value of money analysis to choose between the annuity and the lump sum.
(b) If you expect to invest $100,000 annually that earns 8% annually on your investments over the next 20 years, calculate the current value of future payments from an annuity. Explain how you would use time value of money analysis to choose between the annuity and the lump sum.
c) Using interpolation based on your answers in part (a) and (b), at approximately what interest rate would you be indifferent when choosing between the two plans?
(d) You can earn 3 percent, compounded monthly at your bank. If you deposit $1,000,000 at age 28, how old will you be when your account has grown to $2,000,000? What is the effective annual rate?
Question 2 Becky Kwok is currently considering investing specified amounts in the following two investment opportunities described below.
• Investment A: Invest a lump sum of $52,000 today in an account that pays 8% annual interest, compounded monthly and leave the funds on deposit for exactly 10 years.
• Investment B: Invest $1,200 at the beginning of each month for the next 5 years in an account that pays 10% annual interest, compounded monthly.
(a) For investment A, draw the necessary timeline and determine the account balance at the end of year 10.
(b) For investment B, draw the necessary timeline and determine the account balance at the end of year 5.
Question 3 Four years ago, SONO Ltd. raised $30 million by issuing 15-year $1,000 par value bonds that carry 6.8% coupon rate, payable semiannually. SONO Ltd. is currently announcing to raise another $20 million by issuing 15-year zero coupon bonds that discount semi-annually. The current YTM on these bonds is 9%.
(a) Calculate the number of the 15-year coupon bonds that SONO Ltd. issued to raise the $30 million four years ago. What will be the company's repayment be at the maturity date of the 15-year coupon bonds?
(b) Calculate the current bond prices of the 15-year coupon bonds and 15-year zero coupon bonds.
(c) Calculate the number of the 15-year zero coupon bonds that SONO Ltd. currently issues to raise the $20 million. What will be the company's repayment be at the maturity date of the 15-year zero coupon bonds?
(d) Are 15-year 6.8% coupon bonds or 15-year zero coupon bonds more sensitive to changes in market interest rates? (2 marks)
given below.
Step-by-step explanation
Q1)
Present value of annuity = P*[1 - (1+r)^-n / r ]
P = Periodical payment
r = Interest rate
n = Number of periods
a)
Present value = 100000*[1 - (1+6%)^-20 / 6% ]
= 1,146,992.12
we compare the present value with Lumpsum Amount ans select the Option That gives higher Present value
Since Present value of Annual payments are higher , Select Annuity payments
b)
Present value = 100000*[1 - (1+8%)^-20 / 8% ]
= 981,814.74
using the same Concept above , here Present value of lumpsum Is higher So select Lumpsum Amount Of 1,000,000
c)
Decrease In NPV when Interest rate decreases 2% = (1146992.12 - 981814.74) = 165,177.38
Indifference Interest rate = 6% + (2% / 165177.38)*(1146992.12 - 1000000) = 7.75%
So at 7.75% Interest rate you will be Indifferent
d)
Future value = Present value*(1+r)^n
r = Periodical Interest rate = 3% / 12 = 0.25%
n = Number of periods = ?
2000000 = 1000000*(1+0.25%)^n
1.0025^n = 2
Apply Log On both sides
n Log(1.0025) = Log(2)
n = log(2) / Log(1.0025)
n = 0.3010 / 0.00108
n = 277.61 Months
n = 277.61 / 12 = 23.13 Years
EAR = (1+(APR/m))^m - 1
m = Number of Compounding periods
EAR = (1+(3%/12))^12 - 1
Effective annual rate = 3.0416%
Q2)
(a) Account balance at the end of year 10 is $115,421

Q3)
Part (a):
Number of 15 year coupon bonds issued 4 years ago= Total value/ Par value per bond
=30000000/1000= 30,000
Repayment at the maturity date:
Redemption of par value $30 million and one semi annual interest of 30 million*6.8%/2= 1.02 million
Total $31.02 million
Part (b):
Current price of 15 year coupon issued 4 years ago= $848.37
Calculation using TI BA II Plus calculator:
Set END
P/Y= 2, C/Y= 2
N= 11*2=22
I/Y= 9
PMT= 1000*6.8%/2= 34
FV= 1000
CPT PV= -848.3713276
Current price of 15 year zero coupon bond= $267 as follows:
N= 15*2= 30
I/Y= 9
PMT= 0
FV= 1000
CPT PV= -267
Part (c):
Number of zero coupon bonds to be issued to raise $20 million= Amount required/Price per bond
=20000000/267= 74,907 (rounded)
Repayment of zero coupon bonds at the maturity date= Number of bonds* face value per bond
=74907*1000 = $74,907,000
Part (d): Sensitivity of bond prices to interest rate changes is dependant on Duration. The more the Macaulay Duration, the more sensitive and vice versa.
Duration of zero coupon bond is its term to maturity which is 15 years.
Since the remaining term to maturity of coupon bond is 11 years, Duration is not more than 11 years.
Hence the zero coupon bond with higher duration is more sensitive
