Types of Capital Investment Decisions

## Types of Capital Investment Decisions

Capital investment decisions are classified on two bases.

---

### Classification 1: Based on Firm's Existence

#### (i) Replacement Decisions

  • Replace an asset whose economic life is over.
  • Aim: Maintain operational efficiency.
  • Also called Cost Reduction Decisions.
  • Example: Replacing a 15-year-old lathe that breaks down frequently.

#### (ii) Modernisation Decisions

  • Upgrade to a technologically advanced machine even before the old one wears out.
  • Aim: Reduce cost, improve quality.
  • Also called Cost Reduction Decisions.
  • Example: Replacing working CNC machines with AI-driven machining centres.

#### (iii) Expansion Decisions

  • Add production capacity to meet rising demand.
  • Also called Revenue Expansion Decisions.
  • Example: Adding a second production line when orders exceed current capacity.

#### (iv) Diversification Decisions

  • Enter new products or new markets to spread risk.
  • Also called Revenue Expansion Decisions.
  • Example: A cement company setting up a ready-mix concrete business.

### Classification 2: Based on Situation

#### (i) Mutually Exclusive Decisions

  • Two or more proposals where accepting one automatically rejects the others.
  • Example: Choosing between buying Machine A or Machine B for the same task.

#### (ii) Accept-Reject Decisions

  • Independent proposals evaluated against a minimum required rate.
  • Accept if: Return ≥ Required rate
  • Reject if: Return < Required rate

#### (iii) Contingent Decisions

  • Dependent proposals—one investment requires another.
  • Example: Setting up a factory in a remote area also requires investing in roads and staff housing.

Worked example

### Example 1

A food processing company has three decisions to make: (a) Replace a 20-year-old conveyor belt (Replacement), (b) Install an IoT-enabled sorting system alongside existing machinery (Modernisation), and (c) Launch a new line of health drinks (Diversification). Each is a different type under the 'firm existence' classification.

### Example 2

A company has ₹10 crore to invest and two proposals: Project A (new plant, same city) and Project B (new plant, different city). It cannot afford both. This is a Mutually Exclusive Decision—it must use NPV or IRR to pick the better one. Separately, it also receives a proposal for a low-cost heat-exchange unit that independently earns 15% vs. WACC of 12%—this is an Accept-Reject Decision, and it should be accepted.

⚠️ Common exam mistakes

  • Treating Replacement and Modernisation as the same—Replacement is end-of-life; Modernisation is a technology upgrade mid-life.
  • Confusing Mutually Exclusive and Contingent decisions—Mutually Exclusive means 'either/or'; Contingent means 'one requires the other'.
  • Classifying Expansion as a Cost Reduction decision—Expansion increases capacity and revenue, so it is a Revenue Expansion decision.
  • Applying Accept-Reject logic to Mutually Exclusive projects—when two projects compete, the one with the higher NPV wins even if both individually exceed the required rate.
