Document Summary
Stream of cash flows = series of cash flows lasting several periods of time. Timeline = linear representation of the timing of expected cash flows. Rule 1: it is only possible to compare or combine values at the same point in time. For cash flows that occur at different points in time, convert into same units or move to same point in time. Rule 2: to move a cash flow forward in time, you must compound it. Rule 3: to move a cash flow back in time, you must discount it. Perpetuity = stream of equal cash flows that occur at regular intervals and last forever. Annuity = stream of n equal cash flows paid at regular intervals. Pv(annuity of c for n periods) = p - pv(p in period n) Pv(annuity of c for n periods with interest rate r) = c x 1/r(1 - 1/(1+r)^n)
