MINIMUM ATTRACTIVE RATE OFRETURN ( MARR )
• An interest rate used to convert cash flows into
equivalent worth at some point(s) in time• Usually a policy issue based on: - amount, source and cost of money available for
investment - number and purpose of good projects available for
investment - amount of perceived risk of investment
opportunities and estimated cost of administeringprojects over short and long run
- type of organization involved
• MARR is sometimes referred to as hurdle rate

CAPITAL RATIONING• MARR approach involving opportunity cost
viewpoint• Exists when management decides to restrict
the total amount of capital invested, by
desire or limit of available capital• Select only those projects which provide
annual rate of return in excess of MARR
• As amount of investment capital andopportunities available change over time, afirm’s MARR will also change

PRESENT WORTH METHOD ( PW )
• Based on concept of equivalent worth of all
cash flows relative to the present as a base• All cash inflows and outflows discounted to
present at interest -- generally MARR
• PW is a measure of how much money can beafforded for investment in excess of cost
• PW is positive if dollar amount received for
investment exceeds minimum required byinvestors

BOND AS EXAMPLE OFPRESENT WORTH
• The value of a bond, at any time, is the present
worth of future cash receipts from the bond• The bond owner receives two types of
payments from the borrower: -- periodic interest payments until the bond is
retired ( based on r ); -- redemption or disposal payment when the bond
is retired ( based on i );
• The present worth of the bond is the sum of thepresent values of these two payments at thebond’s yield rate
![Page 10: 180211 Applications](https://reader036.vdocuments.site/reader036/viewer/2022062413/577d2b2d1a28ab4e1eaa79fe/html5/thumbnails/10.jpg)

PRESENT WORTH OF A BOND• For a bond, let Z = face, or par value C = redemption or disposal price (usually Z ) r = bond rate (nominal interest) per interest period N = number of periods before redemption
i = bond yield (redemption ) rate per period
VN = value (price) of the bond N interest periods
prior to redemption -- PW measure of merit VN = C ( P / F, i%, N ) + rZ ( P / A, i %, N )
• Periodic interest payments to owner = rZ for N periods-- an annuity of N payments
• When bond is sold, receive single payment (C), based
on the price and the bond yield rate ( i )

ANNUAL WORTH METHOD ( AW )• AW is an equal annual series of dollar amounts, over
a stated period ( N ), equivalent to the cash inflowsand outflows at interest rate that is generally MARR
• AW is annual equivalent revenues ( R ) minus annualequivalent expenses ( E ), less the annual
equivalent capital recovery (CR) AW ( i % ) = R - E - CR ( i % )
• AW = PW ( A / P, i %, N )
• AW = FW ( A / F,i
%, N )• If AW > 0, project is economically attractive
• AW = 0 : annual return = MARR earned

CAPITAL RECOVERY ( CR )• CR is the equivalent uniform annual cost of the
capital invested• CR is an annual amount that covers:
– Loss in value of the asset
– Interest on invested capital ( i.e., at the MARR ) CR ( i % ) = I ( A / P, i %, N ) - S ( A / F, i %, N ) I = initial investment for the project
S = salvage ( market ) value at the end of thestudy period N = project study period

INTERNAL RATE OF RETURN METHOD ( IRR )• IRR solves for the interest rate that equates the
equivalent worth of an alternative’s cashinflows (receipts or savings) to the equivalentworth of cash outflows (expenditures)
• Also referred to as:
– investor’s method – discounted cash flow method
– profitability index
• IRR is positive for a single alternative only if: – both receipts and expenses are present in the
cash flow pattern
– the sum of receipts exceeds sum of cashoutflows

INTERNAL RATE OF RETURN PROBLEMS
• The IRR method assumes recovered funds, if
not consumed each time period, arereinvested at i ‘ %, rather than at MARR
• The computation of IRR may be
unmanageable• Multiple IRR’s may be calculated for the same
problem
• The IRR method must be carefully applied andinterpreted in the analysis of two or morealternatives, where only one is acceptable

THE EXTERNAL RATE OF RETURN METHOD( ERR )
• ERR directly takes into account theinterest rate ( ε ) external to a project atwhich net cash flows generated over the
project life can be reinvested (or borrowed ).
• If the external reinvestment rate, usually
the firm’s MARR, equals the IRR, thenERR method produces same results asIRR method

ERR ADVANTAGES
• ERR has two advantages over IRR:
1. It can usually be solved for directly, rather than by trial anderror.
2. It is not subject to multiple ratesof return.
