6. Mixed stream cash flows and annuities differ because:
mixed streams are inflows and annuities are outflows
mixed stream payments occur at the end of each period, whereas annuity payments occur
at the beginning of each period
the future value of a mixed stream is the sum of the future values of the individual cash
flows, but the future value of an annuity is simply the future value of the annuity’s annual
payment
the present value of a mixed stream is easier to calculate than the present value of an
annuity
mixed streams follow no particular pattern of cash flows; however, annuities are streams
of equal periodic cash flows
7. Which statement is false?
The future value of an annuity due would be greater than the future value of a comparable
ordinary annuity.
The present value of an annuity due would be smaller than the present value of a
comparable ordinary annuity.
Equations for the present value (future value) of an ordinary annuity can be converted to
the present value (future value) of an annuity due by multiplying by (1 + r).
The future value of an annuity due is always greater than the future value of a comparable
ordinary annuity because each cash flow of an annuity due earns an additional year of
interest.
The equation for the present value of an annuity due accounts for the fact that each cash
flow for an annuity due occurs one period earlier than for an ordinary annuity.
8. The present value of a perpetuity:
equals the annual, end-of-year payment divided by the discount rate
is calculated using the same equation as the present value of an annuity due
is found by dividing the present value of the infinite annuity stream by (1 + r)
cannot be calculated if the cash flows do not remain constant over time
9. Sue was evaluating an investment opportunity with equal end of period cash flows, when she realized
she would need a 10% return rather than an 8% return. Since the equal expected cash flows did not
change, Sue should:
pay the same amount in present dollars for the investment
make certain the investment is not an annuity due
pay less in present dollars for the investment
try to increase the length of time she will hold the investment
pay more in present dollars for the investment
10. For a given stated annual rate, the effective annual rate (EAR):
can be found by dividing the stated rate by the number of compounding periods
increases as compounding frequency increases
