IRRC Dilution Data can be accessed regular Kellogg faculty and doctoral students only.


The IRRC collects information on year-end outstanding grants, weighted average exercise price of options outstanding and weighted average contractual life of outstanding options, as well as information on new grants and option exercises. The data includes all options granted, collected from 10K and proxy disclosures, for firms in the S&P 500, the S&P Mid Cap 400 and the S&P SmallCap 600 indeces. Kellogg purchased four years of data between 1997 and 2004.
