(a) Calculate the net present value (NPV) of a project which
requires an initial investment of $243,000 and it is expected to
generate a cash inflow of $58,000 each month for 12 months. Assume
that the salvage value of the project is zero. The target rate of
return is 12 % per annum.
(b) An initial investment of $8,720 thousand (i.e. × 1,000) on
plant and machinery is expected to generate cash inflows of $3,411
thousand, $4,070 thousand, $5,824 thousand and $2,065 thousand at
the end of first, second, third and fourth year respectively. At
the end of the fourth year, the machinery will be sold for $900
thousand. Calculate the net present value (NPV) of the investment
if the discount rate is 18 %. Round-off your final numerical answer
to the nearest thousand dollars.
(c) Suppose you make an annual contribution of $20,000 to your
investment-linked product account at the beginning of each year for
five years. If your investment provides 16 % annual returns to your
investment, what is your asset value (by annual-compounding) in
your account at the end of five years? Also, draw the corresponding
cash flow diagram with all key labels indicated clearly.
(d) With reference to part (c), assume the investment-linked
product account will keep running without any further contribution
and the annual return keep 16 % pa. If you withdraw $80,000 at the
8th year (after interest compounding), what is your account value
at the end of 10th year?
(a) Initial Investment = $243,000
Net Cash Inflow per Period = $58,000
Number of Periods = 12
Discount Rate per Period = 12% ÷ 12 = 1%
Net Present Value = $58,000 ×(1 −(1 + 1%)-12) ÷ 1% −$243,000
= $58,000 ×(1 −1.01-12) ÷ 0.01 −$243,000
≈ $58,000 ×(1 −0.887449) ÷ 0.01 −$243,000
≈ $58,000 ×0.112551 ÷ 0.01 −$243,000
≈$58,000 ×11.2551 −$243,000
≈ $652,795.8 −$243,000
≈ $409,795.8
(b) PV Factors:
Year 1 = 1 ÷ (1 + 18%)1 ≈ 0.8475
Year 2 = 1 ÷ (1 + 18%)2 ≈ 0.7182
Year 3 = 1 ÷ (1 + 18%)3 ≈ 0.6086
Year 4 = 1 ÷ (1 + 18%)4 ≈ 0.5158
