WhataretheinvestmentIRR'andNPV?
SOLUTION:
Wehavetofindtheincrementalcashflowsresultingfromthisinvestment.Therearetwomethodsthatwecanusetofindtheaftertaxcashflow.
1.Findthe(incremental)netincome,thenadd(incremental)depreciation.Hence:
Annualdepreciation(usingstraight-linemethod)=$10MM/4=$2.5MM
Pretaxincomeincreasesby:
$4MM-$2.5MM=$1.5MM
Netincomeincreaseby:
1.5x(1-0.4)=$0.9MM
Addingbackdepreciation(noncashexpense):
OCF=0.9+2.5=$3.4MM
2.Addthedepreciationtaxshieldtotheafter-taxincrementalcostsaving.Hence,theyearlyOCFfromyear1to4is:
4x(1-0.4)+2.5x0.4=$3.4MM

SOLUTION:

Theexpectedannualnetcashflowcanbederivedusingtheformula:
