Cash and Value Relationship between cash (cash flows) and value:
The value of an investment is determined by the futurestream of cash flows that the investment generates forthe investor

Time value of moneyYou are asked to choose from the following: Receive $100 today Receive $100 one year from now
Would you choose 1 or 2?
Basic principle: A dollar today is worth more than adollar tomorrow because the dollar today can beinvested to grow to an amount greater than a dollartomorrow

The Formula for Future Value The formula lets you convert a current cash flow intoits future value.
This process is called compounding.
What about the reverse process? How do we convertfuture cash flows into their present values?
Definition: The present value of a future cash flow Nperiods from today is the amount, if invested today,will grow to equal that future value

Multi-period, Find PVFind the present value of $6,000 that occurs at t = 6.The discount rate is 14 percent.
Use PV = FV6/(1+r)6
FV6=6000, N = 6, r = 14, PV = ?

Use FV33 = PV x (1+r)33
PV=150, N=33,r=6, FV33=?

You remember that you hadopened this account quite some years ago with aninitial deposit of $19,000. You forget when the initialdeposit was made.

Calculating the Net Present Value Calculating the NPV of future cash flows allows us toevaluate an investment decision.
Net Present Value compares the present value of cashinflows (benefits) to the present value of cash outflows(costs).

Annuity Due 1 Up till now, we have dealt with ordinary annuities. For an ordinary annuity, payment occurs at the endof each period.
For an annuity due, payment occurs at the beginningof each period.
The difference becomes clear when we look at time lines.

Is there a relationship between ordinaryannuity and annuity due?Yes !
PV of annuity due= (PV of ordinary annuity) x (1 + r)
FV of annuity due= (FV of ordinary annuity) x (1 + r)
Note: The terms ordinary annuity and regular annuity mean the samething.

= (PV of ordinary annuity) x (1 + r)FV of annuity due
= (FV of ordinary annuity) x (1 + r)

Continuous compounding (1)Continuous compounding is a special case ofcompounding more often than once a year. In thiscase, the compounding frequency is infinity.
FV = PV x erNPV = FV x e-rN
e is the exponential function (that appears on yourfinancial calculator as [ex]), r is the stated interestrate, and N is the number of years.Foundations of Finance - I 56
