Green Green Green
 

Green:indicates performance within an expected performance level where the associated cornerstone objectives are met.
White:represents performance outside an expected range of nominal utility performance but related cornerstone objectives are still being met.
Yellow:indicates related cornerstone objectives are being met, but with a minimal reduction in the safety margin.
Red:signals a significant reduction in safety margin in the area measured by the performance indicator.
