The objective of Chapter 13 is to
give the student an understanding
of the basic components of the
capital budgeting process so that
the important role of the engineer
in this complex and strategic
function will be made clear.

Capital financing and allocation
functions are primary components of
capital budgeting.
• Capital financing determines funds needed from
investors and vendors—in the form of additional
stock, bonds, loans—and funds available from
internal sources.
• Capital allocation is where the competing
engineering projects are selected. The total
investment is constrained by decisions made in
capital financing.

Management must make the decisions
for the financing/allocation connection
• Companies establish the allocation proposal
process.
• Management must select projects that ensure a
reasonable return to investors, to motivate
additional investment when required.
• In summary, these decisions are how much and
where financial resources are obtained and
expended.

Debt capital represents borrowed money.
• Companies can borrow money from lenders (e.g.
banks) or can issue bonds or debentures.
• Creditors get interest, bondholders get dividends
and face value at maturity.
• The cost of bond financing depends on the bond
rating, which is dependent on the financial health
of the company.
• Investors have a risk-free alternative of U.S.
government treasure bills. This risk-free rate of
return is denoted RF.

Interest paid on corporate debt is tax
deductible. This savings can be handled
in two different ways.
• Interest can be deducted each year before taxes are
computed. This approach adds more computation,
and it is generally difficult to assign debt
payments to a specific project.
• The most commonly used is to modify the MARR
to account for the tax deductibility of the debt.
• The cost of debt capital is denoted ib.

Equity capital represents money already
in the firm.
• This can be capital held by stockholders through company stock.
• It can also be earnings retained by the company for reinvestment purposes.
• The percentage cost of equity funds, ea, can be estimated in many ways, perhaps the best of which is using the capital asset pricing model (CAPM).

any stock depends on its risk relative to
the market. The risk premium of any
stock is proportional to its beta.

In the first fiscal quarter of 2009 Dell Computer
showed total debt of $1.98mil and total equity of
$3.55mil. Assume Dell’s beta is 2.2, the cost of debt is 7%, and Dell’s effective income tax rate is 0.35. What is the WACC?

Each company may have an “optimal” mix of debt and equity, minimizing the
WACC.
• One task of a company treasurer is to
identify and maintain this mix.
• A constant debt/equity mix is difficult to
maintain over time.
• The separation principle specifies that the
investment decisions (project selection) and
financing decisions should be separated.

Establishing the minimum attractive rate
of return (MARR).
• If risks are roughly normal, the WACC is an
appropriate hurdle rate (i.e., MARR).
• WACC is a floor on the MARR, which should be
increased to reflect more risk.
• Management may choose to set the MARR based
on many factors, such as conserving capital in
anticipation of large future opportunities, or
encouraging new ventures. This may also be
differential across divisions.

Opportunity costs and MARR
• In this chapter we focus on independent projects.
• The opportunity cost viewpoint is a direct result of
capital rationing, when limited funds are available
for competing proposals.
• Prospective projects (of similar risk) are ranked in
order of profitability. The cut-off point falls such
that the capital is used on the better (more
profitable) projects.
• Firms may set two or more MARR levels,
analyzing within particular risk categories.

Selecting projects that are not mutually
exclusive has multiple considerations.
• Those projects that are most profitable should be
selected, allowing for
– intangibles and nonmonetary considerations
– risk considerations
– availability of capital
• In certain cases monetary return is of minor
importance compared to other considerations, and
these require careful judgment.

any number of different ways, some of
which are given below.

involved
• Priority—essential,
necessary, desirable,
or improvement

• Facility replacement,
facility expansion, or
product improvement.

affected by other

Organizing for capital allocation
• Organizations generally have a formal project
selection process that progresses through the
organizational levels.
• Clearly “good” proposals, or proposals clearly executing corporate policies, can be approved at
the division level, within certain funding limits.
• Proposals requiring a commitment of a large
amount of funds are sent to higher levels in the
organization (see the table on the next slide).

The process of communicating and
“selling” project proposals is important.
• Good communication is required regardless of the
strength of the project proposal.
• Consider the needs of the decision maker.
• Provide investment requirements, measures of
merit, and other benefits, and
– bases and assumptions used for estimates
– level of confidence in the estimates
– how would the outcome be affected by variation?
• A corporate-wide proposal structure is helpful.

For improved capital budgeting, conduct
postmortem reviews (postaudits).
• It helps determine if planned objectives of the
project were obtained.
• It determines if corrective action is needed.
• It improves estimating and future planning.
• It provides an unbiased assessment of project
results compared to the proposed outcomes.
• Postaudits are inherently incomplete, so care
should be used decisions based on these results.

Budgeting for capital investments is a
difficult managerial challenge.
• Just because a project is “attractive” doesn’t mean it should be undertaken.
• Capital budgets, while perhaps with a one- or two-
year horizon, should be supplemented with a long-
range capital plan.
• Technological and market forces change rapidly.
• Decisions must be made regarding investing now
or “saving” some funds to invest in the future (e.g., next year), postponing returns.

Lease vs. buy vs. status quo decisions
• Leases allow the firm to use available capital for
other uses.
• Leases are legal obligations very similar to debt,
reducing the ability to attract further debt capital
and increasing leverage.
• One should not compare only lease and buy, but
also the status quo (do nothing), separating to the
extent possible the equipment and financing
decisions.
• Always consider tax implications.

One way to allocate capital among
independent projects is to create MEAs
from the set of projects and use familiar
equivalent worth methods.
• Project risks should be about equal
• Enumerate all feasible combinations (those
that meet any budget constraints).
• The acceptance of the best MEA will
specify those projects in which to invest.

Capital allocation problems can be
modeled as linear programs.
• “Brute force” evaluation of all independent alternatives, especially when the number of
alternatives is very large, is cumbersome at best.
• Linear programming can be used to determine an
optimal portfolio of projects.
• Linear programming is a mathematical procedure
for maximizing (or minimizing) a linear function
subject to one or more linear constraints. We will
present the formulation of problems, but not the
solution, which is beyond our scope.
