8. Receiving $100 one year from today is worth less than $100 today because a
return can be earned on a $100 investment during the year. If $100 to be
received one year from today is discounted at 12%, the present value is $100 x
0.8929 = $89.29 (the present value factor is taken from Table B.1). This means
that if $89.29 is invested at 12% for one year, it will be worth $100 at the end of
that year. This amount also can be found by dividing $100 by 1.12.
9. The internal rate of return is the rate that produces a net present value of zero. If
the internal rate of return is higher than the company’s hurdle rate, it means that
the net present value of the project is positive, and the company should make
the investment.
11. An investment of this nature in technology is risky for many reasons: (1) Samsung
cannot be 100% certain of the costs and benefits of such a system; (2) there is a
great amount of money involved; (3) the investment involves a long-term
commitment, (4) it may be difficult to reverse the decision once they have committed
to it, even if it looks like it will turn out poorly; and (5) new technology is always
risky due to innovation and uncertainty.
12. Some of the costs and benefits are: cost of the new equipment; cost savings from
operating the new equipment over the life of the equipment; training costs for
workers. All of these cash flows need to be evaluated using Google’s hurdle rate of
return.
13. Apple management could use one of the following common methods to evaluate the
potential investment in the expansion: payback period, accounting rate of return, net
present value, or internal rate of return.
