## 3. How To Handle Uncertainty

10- 3
How To Handle Uncertainty
Sensitivity Analysis - Analysis of the effects of
changes in sales, costs, etc. on a project.
Scenario Analysis - Project analysis given a
particular combination of assumptions.
Simulation Analysis - Estimation of the
probabilities of different possible outcomes.
Break Even Analysis - Analysis of the level of
sales (or other variable) at which the company
breaks even.
McGraw Hill/Irwin

## 4. Sensitivity Analysis

10- 4
Sensitivity Analysis
Example
Given the expected cash flow
forecasts for Otobai Company’s
Motor Scooter project, listed on
the next slide, determine the
NPV of the project given
changes in the cash flow
components using a 10% cost of
capital. Assume that all
variables remain constant, except
the one you are changing.
