The WB Tool

Not based on the simple average,
Not based only on the weighted average,
Is based on a combination of weighted averages
and pre-conditions.
The tool’s structure, weights, and the pre-conditions constitute
the assumptions of the model and were decided on during the
model-building phase. These can be seen on the “Weights” page
of the National Vulnerability and Banking Sector Excel
templates.
