Cash Flows Versus Profit Cash flow is not the same thing as profit, at least, for two reasons: ±
profit, as measured by an accountant, is based on accrual concept. First ,
Second , for computing profit, expenditures are arbitrarily ± divided into revenue and capital expenditures. CF = (REV (REV EXP DEP) DEP) (1(1-T) T) + DEP DEP CAPE CAPEX X CF = (EBIT)(1-T) (EBIT)(1-T) + DEP CAPEX = PROFI PROFIT T + DEP DEP - CAPEX CAPEX

Net Working Capital Change in receivable Change in inventory Change in payable.
Instead of adjusting each item of working capital, we can simply adjust the change in networking capital, viz. the difference be betw twe een ch cha ange in cu curr rre ent as asssets (e (e.g .g., ., receiv iva able and an d in inve vent ntory ory) and chan ang ge in current liabilitie iess (e.g .g.. accounts payable) to pr prof ofit it.. Increase in net working capital should be subtracted from and decrease added to after-tax operating profit .
Thus, net cash flo low: w:
NCF = EBIT (I -T) + DEP NWC Where NWC is net net worki orking ng capi capittal al..
(6)
Free Cash Flows In addition to an initial cash outla lay y, an investme men nt project may require some reinvestment of cash flow (for example, replacement in inv vestment) for maintaining its revenuegenerating ability during its life. As a consequence, net cash flow will be reduced by cash outflow for additional capital expe xpendi nditur tures es (CAPEX). Thus, net cash flow equation will be as follow:
NCF = EBIT (1 -T) + DEP -NWC -CAPEX
BASIC PRINCIPLES OF CASH FLOW ESTIMATION ESTIMATION
Separation Principle
Incremental Principle
Post-tax Principle
SEPARA SEP ARATION TION PRINC PRINCIPLE IPLE Cash flows associated with the investment side and the financing side of the project should be separated.
While defining the cash flows on the investment side, financing financi ng costs should not be considere considered d because because they will be reflect reflected ed in the cost of capital figure against against which the rate of return figure will be evaluated.
INCREMENTAL INCREMENT AL PRINCIPLE PRI NCIPLE To ascertain a projects incremental cash flows you have to look loo k at what happ happen enss to the cash flows flows of the firm with the the project and without the project Guidelines
Consider all incidental effects
Ignore sunk costs
Include opportunity costs
Question the allocation of overhead costs
Estimate working capital properly
POST-T POST -TAX AX PRINCIPL PRINCIPLE E
Cash flows should be measured on a post-tax basis

Suppose you own a plot of land that presently has a market value of Rs 1 mn. If you keep it for a year, it is expected to fetch you Rs 1.2 mn. You come across another plot of land that will cost you Rs 1.5 mn now. If you buy this land you hope to sell it for Rs 2 mn a year hence. Should you replace the existing plot? Assume no taxes and no operating cash flows.
Cash flows for the replacement
decision
ostt - Aft After er ttax ax sa salv lvag age e Initial investment = Cos value of the old plot. Rs 1.5 mn 1 mn = Rs 0.5 mn. Operating cash flow = 0
Terminal flow = After tax salvage value from the new plot After tax salvage value of the old plot had it been retained. = Rs 2 mn Rs 1. 1.2 2 mn = R Rss 0 0.8 .8 mn
Thus, the relevant cash flow stream of this replacement proposal is: replacement Cash flow Year 0 1
-Rs 5,00,000 Rs 8,00,000
If you dont subtract theget salvage value value of the tcash he existing a year from now, you the following flow plot stream for the replacement proposal: Year Cash flow 0 - Rs 5,00,000 1 Rs 20,00,000 This is erroneous because it considers the advantage fr from om selling the plot today but overlooks the disadvantage expected a year from now now..
Depreciation Base In a replacement decision, the depreciation base of a new asset will be equal to:
Cost of new equipment
+Written down value of old equipment
-Salvage value of old equipment
Illustration 2 ABC company purchased a machine three years ago at a cost of
Rs10,000. The machine had a life of 8 years at the time of its purchase. It is being depreciated at 15% on decl declin inin ing g bala balanc nce. e. The company is thinking of replacing it with a new machine costing Rs20 Rs 20,0 ,000 00 with with an expec xpectted 5 year ear lif life. The Th e prof profit it bef before ore depr eprecia eciattion ion is esti estima matted to incr incre eas ase e by Rs4, Rs4,44 445 a year. Assume that the old and new machines will be now depreciated at 25% on decli eclin ning ing balan alance ce for tax purpose poses. s. The salvage value of the new machine is anticipated as Rs500 after 5 years.
The market value of the old machine today is Rs11,500. It is
estima esti mate ted d to ha hav ve zero ero salv salvag age e val alue ue after fter 5 years. The income tax may be assumed as 55%. The companys ys after tax cost of capital is 12 percent. Should the new machine be bought?
The book value of the old machine today is Rs6,141 as shown below:

The total proceeds from the sale of the old machines Rs11, 500. Since a new machine (cost Rs20,000) is being acquired in the block to which the old machine belonged, the depreciation base will be as follows: follows:
=Cost of new machine + Book value of old machine Salvage value of old machine
=20,000 + 6,141 11,500 = 14,641
