A	review	of	Basics:
Present	Value,	Net	Present	value	and		future	value
• Present	value (PV)	is	the	current	worth	of	a	future	sum	of	money	or	
stream	of	cash	flows	given	a	specified	rate	of	return.	In	other	words,	
present	value,	also	known	as present discounted value,	is	
the value of	an	expected	income	stream	determined	as	of	the	date	of	
valuation
• Difference	between	a	project’s	value	and	its	cost	is	its	NPV
• Future	value is	the value of	an	asset	at	a	specific	date.	It	measures	
the	nominal future sum	of	money	that	a	given	sum	of	money	is	
"worth"	at	a	specified	time	in	the future assuming	a	certain	interest	
rate,	or	more	generally,	rate	of	return;	it	is	the	
present value multiplied	by	the	accumulation	function.
Few	formulas
Discount	factor;	1/(1+r)
t
PV=	C1/1+r		+	C2/(1+r)2 .	.	.	+	Ct/(1+r)t	
Present	value	=	DF2*	C2
NPV	=	Investment	+	PV
A	review	of	Basic:	Example
• a	CEO	of	corporation	is	looking	to	invest	$	1	million	in	project	X
• He	asks	from	you	(FINANCIAL	MANAGER)	whether	to	invest	or	not,	
and	if	yes	then	what	should	be	the	grounds
Your	answer	may	be:
first:	forecast	the	cash	flows	may	be	generated	by	the	project
Second:	determine	the	appropriate	opportunity	cost	of	Capital.	
That	should	reflect	both;	time	value	of	money	and	Risk	factor
Third: use	the	opportunity	cost	of	capital	to	discount	the	
project's	future	cash	flows
Fourth:	 calculate	NPV	by	subtracting	the	1	million	investment	
from	present	value:	(Both	formulas	are	given	below)
PV=	C1/1+r		+	C2/(1+r)2 .	.	.	+	Cn/(1+r)t NPV=	C0 +C1/1+r		+	C2/(1+r)2 .	.	.	+	Cn/(1+r)t
Note: Invest	in	Project		if	its	NPV	is	greater	or	equal	to	zero
Net	Present	Value
• Example:	building	costs	700,000	it	can	be	sold	for	$ 800,000.	if	the	discount	
rate	is	10%,	calculate:
§ Present	Value
§ Net	Present	Value
PV=	C1/1+r		+	C2/(1+r)2 .	.	.	+	Cn/(1+r)n
=800,000/(1+.10)
PV=		RS.	727273
NPV=	C0 +C1/1+r		+	C2/(1+r)2 .	.	.	+	Cn/(1+r)n
=	700,000	-727273
NPV=		$ +27273
NPV	Strengths	
and	Weaknesses
Strengths:
• Cash	flows

• Accounts	for	TVM.
• Considers	all	
cash	flows.
Weaknesses:
• May	not	include

options	embedded	
in	the	project.		See

A	review	of	Basic:	Example		…	continue
• CEO	asks,	why	Greater	NPV	is	so	important?
You	answer:
NPV		is	important	as	if	the	firm	does	not	earn	equal	or	more	than	what	the	
shareholders	expect	than	they	might	sell	their	share	in	the	market.
“	Investors	would	forecast	the	dividends	that	Project	X	pay	and	discount	
those	dividends	by	the	expected	rate	of	return	of	securities	having	similar	
risk.”	
ØOnly	thing	to	answer	is	where	the	discount	rate	comes	from?
It	is	the	opportunity	cost	of	investing	in	the	project	rather	than	in	
the	capital	market.
if	the	firm	does	not	earn	from	the	project	what	its	shareholders	
expect	(cost	of	capital)	than	it	should	return	the	cash	to	the	
shareholders	and	let	them	to	invest	in	Financial	Markets	by

Important	Points	to	be	remembered	about	Net	Present	Value
• First:	NPV	rule	recognizes	that	a	$	today	is	worth	more	than	a	$	
tomorrow	(time	value	of	money).
• Second:	NPV	depends	on	the	forecasted	cash	flows	from	the	project	
and	the	opportunity	cost	of	capital
• Third:	PV		measures	in	todays	money,	therefore	we	add	them	up.
• NPV	depends	on	Cash	flows,	not	on	book	returns.	Book	returns	are	
the	accounting	record	rather	than	cash	as:
Book	rate	of	Returns=	book	income/book	assets
Capital	Budgeting	
The	Capital	Budgeting	Process	of
generating	Investment	Project	Proposals	and
estimating	Project	“After-Tax	Incremental	Operating	Cash	
Flows”
The	Capital	Budgeting	
Process
• Generate	investment	proposals	consistent	
with	the	firm’s	strategic	objectives.
• Estimate	after-tax	incremental	operating	
cash	flows	for	the	investment	projects.
• Evaluate	project	incremental	cash	flows.
The	Capital	Budgeting	
Process
• Select	projects	based	on	a	value-maximizing	
acceptance	criterion.
• Reevaluate	implemented	investment	projects	
continually	and	perform	post	audits	for	completed	
projects.
Classification	of	Investment	
Project	Proposals
1.			New	products	or	expansion	of	existing	
products
2.			Replacement	of	existing	equipment	or	
buildings
3.			Research	and	development
4.			Exploration
5.			Other	(e.g.,	safety	or	pollution	related)
Payback	method
• Payback	period in	capital	budgeting	refers	to	the period of	time	
required	to	recoup	the	funds	expended	in	an	investment,	or	to	reach	
the	break-even	point.	
For	example,	a	$1000	investment	which	returned	$500	per	year	would	
have	a	two-year payback	period.	The	time	value	of	money	is	not	taken	
into	account.

Why	payback	can	give	misleading	answers
• Payback	rule	ignores	all	cash	flows	after	the	cutoff	date.
• Its	rule	gives	equal	weight	to	all	cash	flows	before	the	cutoff	date
• Companies	still	frequently	use	it	because	it	is	the	simplest	way	to		
communicate	the	idea.	
• Everyone	can	understand	it
• Manager	like	it	as	it	tell	short	span	period;	good	for	their	promotion
PBP	Strengths	
and	Weaknesses
Strengths:
• Easy	to	use	and							
understand
• Can	be	used	as	a	
measure	of	
liquidity
• Easier	to	forecast	 ST	
than	LT	flows
Weaknesses:
• Does	not	account	
for	TVM
• Does	not	consider	
cash	flows	beyond

•
Internal	Rate	of	Return	(IRR)
IRR is	the	discount	rate	that	equates	the	present	
value	of	the	future	net	cash	flows	from	an	
investment	project	with	the	project’s	initial	
cash	outflow.

Sensitivity	analysis
• Uncertainty	means	more	things	can	happen	than	will	happen.
• Example
A	company	is	introducing	new	scooters	for	city	use	with	Rs.	15	b	Net	
investment	for	10	years,	producing	NCF	of	Rs.	3	B	in	ten	years.	Staff	have	
prepared	the	forecasts	at	10%	NPV.
= (-15)+3/(1.1)10 =	Rs.	+3.43	billions
Production	department	estimated	cost	per	unit	is	Rs.	300,000		and	100,00	
scooter	can	be	made	in	the	year.	If	calculated	the	revenue	as	the	firm	has	1%	
market	share,	it	will	be:
Unit	sales=	new	product	share	in	market*size	of	scooter	market
37.5	billions(Revenue)						=	100,000*375,000
Sensitivity analysis is the study of how the uncertainty in the output of a mathematical model or
system (numerical or otherwise) can be apportioned to different sources of uncertainty in its inputs.

• Suppose	that	production	department	is	worried	about	the	machine	which	will	
not	work	properly	and	the	firm	has	to	purchase	another	method	which	incure
per	unit	cost	an	extra	Rs.	20,000:

Scenario	analysis
• Scenario	analysis is	a	process	of	analyzing	possible	future	events	by	
considering	alternative	possible	outcomes	(sometimes	called	
"alternative	worlds").
• Thus,	the scenario	analysis,	which	is	a	main	method	of	projections,	
does	not	try	to	show	one	exact	picture	of	the	future.
