13.1 CAPITAL EXPENDITURES
The Importance of the Capital Expenditure Decision
Capital expenditures (capex) are a firm's investments in long-lived assets. These may be tangible
assets — property, plant, and equipment — or intangible assets such as research and development
(R&D), copyrights, brand names, and franchise agreements. Tangible assets are physical and easier to
borrow against; intangible assets are more abstract and lenders cannot easily secure debt against
them.
Capex decisions are arguably the most important decisions a firm can make, for three interconnected
reasons:
• They involve large sums of money — individual projects can be worth billions of dollars (e.g., the
Mackenzie Valley Pipeline was estimated at $7B in 2007, rising to $16B+ by 2011).
• They are frequently irrevocable — once a pipeline is built or a new product launched, the
investment costs are largely unrecoverable if the decision turns out to be wrong (sunk costs).
• They determine the firm's future direction — capex decisions dictate what risks the firm takes on
and can affect the firm's long-term survival. Ford's survival in the 1980s hinged on the success of
the Ford Taurus.
Capital Budgeting — The Four-Stage Process
Capital budgeting is the formal process by which firms make capital expenditure decisions. It follows
four sequential stages:
• Stage 1 — Identify investment alternatives: Generate a set of viable projects consistent with the
firm's strategy (e.g., new product development, equipment replacement, expansion).
• Stage 2 — Evaluate these alternatives: Apply financial evaluation criteria (NPV, IRR, payback, PI,
etc.) to determine which projects add value. This is the primary focus of Chapter 13.
• Stage 3 — Implement the chosen investment decisions: Execute approved projects in accordance
with the plan.
• Stage 4 — Monitor and evaluate implemented decisions: Track actual performance vs.
projections; feed lessons back into future decisions. This stage is covered primarily in managerial
accounting.
Strategic Context — Porter's Five Forces and Competitive Advantage
Michael Porter argues that every firm's capex decisions must be linked to its competitive strategy.
Porter identifies five forces that determine an industry's attractiveness:
• Entry barriers — the difficulty for new competitors to enter the market.
• Threat of substitutes — the availability of alternative products that could reduce demand.
• Bargaining power of buyers — how much leverage customers have over pricing.
• Bargaining power of suppliers — how much leverage input providers have over costs.
, COMM 309 | Chapter 13: Capital Budgeting, Risk Considerations, and Other Special Issues | Page 2
• Rivalry among existing competitors — the intensity of competitive pressure within the industry.
Firms have little control over their industry's attractiveness after entering it, but they can create
competitive advantages by adopting one of two strategies — both of which directly shape capex
decisions:
• Cost leadership: Strive to be the lowest-cost producer through economies of scale, proprietary
technology, or privileged access to raw materials. Capex should be directed toward productivity-
enhancing investments that lower unit costs (e.g., replacing aging equipment with the latest
technology). This strategy typically drives replacement decisions.
• Differentiation: Offer products that are unique in their physical characteristics, technology, delivery
alternatives, or brand positioning. Capex is directed toward new product development and
innovation. This strategy typically drives new product development decisions.
📌 Competitive Advantage and Capex — Key Link
Porter notes that competitive advantages are difficult to sustain because competitors imitate successful
strategies. Therefore, firms must CONTINUOUSLY invest (both in new products and in cost-reducing
technology) to maintain their position.
Implication for capital budgeting: A firm that fails to invest effectively will fall into a competitive
disadvantage that, in the extreme, threatens long-term survival. Poor investment decisions reduce the
market value of the firm's debt and equity, raising its cost of capital.
IMPORTANT: Finance holds that when a senior executive justifies a project on NON-FINANCIAL
grounds alone, either the analysis is insufficiently rigorous (advantages not fully quantified) or the project
is a 'pet project' that should not be pursued. Every project is amenable to DCF analysis — the only
difference is the quality of the inputs.
Bottom-Up vs. Top-Down Analysis
Two fundamentally different approaches to capex decisions exist, differing not in the analytical
framework (which is identical — DCF) but in the quality and nature of the inputs:

Discounted Cash Flow (DCF) Methodologies
All capital budgeting evaluation techniques discussed in this chapter fall under the umbrella of
discounted cash flow (DCF) methodologies — they estimate future cash flows and compare their
discounted present values with the investment outlays required today. DCF methods are conceptually
identical to bond and share valuation:
• Bond valuation (Ch. 6): Discount fixed coupon and face value cash flows → find bond price or
YTM.
• Share valuation (Ch. 7): Discount expected future dividends → find share price.
• Capital budgeting (Ch. 13): Discount expected future project cash flows → find NPV or IRR.
The key practical difference: in bond/share valuation, the analyst cannot change the cash flows. In
capital budgeting, the analyst CAN change the structure of the project (defer it, redesign it, alter its
scope), making DCF capex analysis an iterative process rather than a single calculation.
13.2 EVALUATING INVESTMENT ALTERNATIVES
A 2011 survey of Canadian CFOs found that the most widely used capital budgeting techniques (in
order of usage frequency) are: NPV (74.6%), IRR (68.4%), Payback Period (67.2%), Discounted
Payback, Profitability Index, and Modified IRR. This section covers all of these in depth.
Payback Period and Discounted Payback Period
The payback period is the number of years required to fully recover the initial cash outlay (CF₀) from the
future after-tax incremental cash flows of a project. It is a simple, intuitive measure — shorter payback
periods are better. Projects are accepted if their payback period is less than the firm's chosen cutoff
date.
Eq. 13-1 | Payback Period T = Payback period (years to recover CF₀)

C F + C F +…+CFT =C F
0 CFt = After-tax incremental cash flow in year t
CF₀ = Initial after-tax incremental cash outlay
T is the smallest value such that cumulative
cash flows equal the initial investment.
For non-integer T: add fraction of the final year
needed = (remaining balance) / (CFT in that year).
Shorter payback = better (less risky).
