7.11.3. Step 4: Analyze Key Variable Changes
7.11.3.1.
In the case of an increase in investment
costs of 20%, the sensitivity indicator is 13.34. This means that
the change of 20% in the variable (investment cost) results in a
change of (13.3 x 20%) = 266% in the FNPV. It follows that the higher
the SI, the more sensitive the FNPV is to the change in the concerned
variable.
7.11.3.2. In the same example, the
switching value is 7.5%, which is the reciprocal value of the SI
x 100. This means that a change (increase) of 7.5% in the key variable
(investment cost) will cause the FNPV to become zero. The lower
the SV, the more sensitive the NPV is to the change in the variable
concerned and the higher the risk with the project.
7.11.3.3. At this point the results
of the sensitivity analysis should be reviewed. It should be asked:
(i) which are the variables with high sensitivity indicators, and
(ii) how likely are the (adverse) changes (as indicated by the switching
value) in the values of the variables that would alter the project
decision?
