Notes:  Net advisory revenues and benchmark revenues are stated on a harvest equivalent basis. A crop year is a two-year marketing window from September of the year previous to harvest through August of the year after harvest. “Survivor averages” are based on advisory programs active in all crop years of a given averaging period.  “Grand averages” are based on all advisory programs active in a given averaging period , whether they “survived” the entire period or not.  The measure of survivorship bias for each averaging period is simply the difference between the survivor and grand averages.  Average differences may not equal the difference between the reported survivor and grand averages due to rounding.
Notes:  N/A denotes "not applicable" -- program did not exist or was not evaluated for that marketing year. Net advisory revenues and benchmark revenues are stated on a harvest equivalent basis. A crop year is a two-year marketing window from September of
