Normalized Production Index
In 2003, we instituted a new factor to demonstrate Intel's performance per unit of production for most of our environmental indicators: the Normalized Production Index (NPI). The NPI is derived directly from our worldwide silicon wafer production and is indexed to a reference or baseline year of 1999. (NPI = 100 for baseline year 1999.)
With this direct correlation to Intel's global manufacturing levels, the NPI will enable more accurate year-to-year comparisons and easier analysis of overall environmental performance. The index also facilitates trending comparisons across semiconductor manufacturers using similar normalization methods.
