This lesson covers the critical task of estimating the cash flows associated with investment projects. It explains the principles of relevant cash flow analysis, the treatment of sunk costs and opportunity costs, and the calculation of incremental cash flows.

• The Importance of Accurate Cash Flow Estimation: The quality of a capital budgeting decision depends fundamentally on the quality of the cash flow estimates. Inaccurate projections may lead to significant financial losses and inefficient allocation of resources.

• Principles of Relevant Cash Flows: Only cash flows that are incremental to the project should be included in the analysis. Key principles include:

  • Focus on Cash Flows, Not Accounting Profits: Capital budgeting is concerned with actual cash inflows and outflows, not accounting income.

  • Consider Incremental Cash Flows: Only the additional cash flows that result from undertaking the project should be considered.

• Treatment of Specific Items:

  • Sunk Costs: Costs that have already been incurred and cannot be recovered are not relevant to the investment decision.

  • Opportunity Costs: The value of resources in their next best alternative use must be included as a cost of the project.

  • Financing Costs: Interest and other financing costs are typically not included in project cash flows but are accounted for through the discount rate (WACC).

• Cash Flow Components: The calculation of project cash flows requires careful consideration of:

  • Initial investment outlay (including capital expenditure and working capital)

  • Operating cash flows during the project life

  • Terminal cash flows (salvage value, recovery of working capital)
