1. The company would have to pay $3,200 from end of year 4 to end of year 10
Present value of a payment = Pmt/ (1+r)n
Pmt is the payment amount, r is the rate of discount, n is the number of periods
Period (n) | Pmt | PV |
0 | 0.00 | |
1 | 0.00 | |
2 | 0.00 | |
3 | 0.00 | |
4 | -3200.00 | -2185.64 |
5 | -3200.00 | -1986.95 |
6 | -3200.00 | -1806.32 |
7 | -3200.00 | -1642.11 |
8 | -3200.00 | -1492.82 |
9 | -3200.00 | -1357.11 |
10 | -3200.00 | -1233.74 |
Total | -11704.69 |
Present worth of the contract = $ (11,704.69)
To find the equivalent annual amount of the contract in years 1 through 10 given the above present value of $ 11,704.69
PVA = A * [((1+r)n - 1)/r*(1+r)n] ………….(A)
[((1+r)n - 1)/r*(1+r)n] can be found out below first:
((1+0.10)10 - 1) / 0.10*(1+0.10)10
(1.1010 - 1) / 0.10* 1.1010
(2.5937424601 - 1) / 0.25937424601
1.5937424601 / 0.25937424601
= 6.1446
So -11,704.69 = A*6.1446
A = -11,704.69 / 6.1446 = -1,904.88
Equivalent uniform amount of contract = $ (1,904.88)
If the company were to pre-pay in years 1 -3
PVA = A * [((1+r)n - 1)/r*(1+r)n]
[((1+r)n - 1)/r*(1+r)n] can be found out below first:
((1+0.10)3 - 1) / 0.10*(1+0.10)3
(1.103 - 1) / 0.10* 1.103
0.33 / 0.13
=2.4869
So A = -11,704.69 / 2.4869 = -4,706.63
So the annual payment from years 1 through 3 would be $ (4,706.63)
2. Future value of a deposit is = (1+r)n where n is the balance periods to the future value date
Period (n) | $ 1 deposit | Balnce periods | Future value at year 10 |
0 | 10 | 0 | |
1 | 9 | 0 | |
2 | 8 | 0 | |
3 | 1 | 7 | 2.210681 |
4 | 1 | 6 | 1.973823 |
5 | 1 | 5 | 1.762342 |
6 | 1 | 4 | 1.573519 |
7 | 1 | 3 | 1.404928 |
8 | 1 | 2 | 1.2544 |
9 | 1 | 1 | 1.12 |
10 | 1 | 0 | 1 |
Total | 12.29969 |
If a $1 deposit according to the above schedule becomes $ 12.2997, then how many $ deposited per year as per above schedule becomes $200,000?
= $200,000 / $ 12.2997 = $ (16,260.56)
If the company makes the first deposit 1 year from now we would need to find an annuity that fits the future value of $200,000 @12% over 10 years
FV = A * ((1+r)n - 1 )/ r
200000 = A ((1.12)10 - 1) / 0.10
200000 = A* 2.1058 / 0.10
A = 200000 / 21.05848
A = $ (9,497.36)
3.a Present value of losses = $ 114.71 million
Period | Losses | PV of losses |
1 | 50 | ($45.45) |
2 | 40 | ($33.06) |
3 | 30 | ($22.54) |
4 | 20 | ($13.66) |
Total | ($114.71) |
3. b Solution is $36.19 million using the PVA formula in eq (A) above (2nd solution of Q 1)
3. c. Solution obtained by dividing the above solution a by the value in below table = $114.71 / 14.7063 = $ 7.80 million in profit per year from year 5 onwards
