PROJECT INTERACTIONS
Erosione.g., diet and regular soft drinks
Enhancemente.g., “The Lion King” & merchandising
Contingent Projectse.g., need road to develop mine
Mutually Exclusive Projectse.g., replacement equipment
PRESENT VALUE OF AN ANNUITY
1. PERPETUITY STARTING NEXT PERIOD
PMT PMT PMT PMT PMT PMT
PV =PMT/r
2. PERPETUITY STARTING AT n
PMT PMT PMT PMT
PV = (PMT/r)/(1+r)n
PV OF N-period annuity = PMT/r - (PMT/r)/(1+r)n =(PMT/r)(1-1/(1+r)n)
ANNUITY PV (CONT.)
• Given annuity PMT, r and n, we can find PV
• Given annuity PV, r and n, we can find PMT
• EAC technique converts an uneven stream into an annuity with same PV

INFLATION & CAP. BUD. (cont.)
To calculate NPV with inflation:Discount nominal cash flows at nominal
discount rate
ORDiscount real cash flows at real discount rate
Watch out for depreciation tax shields
