## 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.
