Note: The selection strategy consists of sorting programs by net advisory price in the first  year of the pair (e.g., t = 1995) and forming groups of programs (thirds,  fourths, top two and bottom two).  Next, the average net advisory price for each group is computed for the first year of the pair. Then, the average net advisory price of the group formed in the first year is computed for the second year of the pair (e.g., t+2 = 1997).  Next, the average net advisory price for the second year is averaged across the comparisons. There are a total of eight comparisons (1995 vs. 1997, 1996 vs. 1998, 1997 vs. 1999, 1998 vs. 2000, 1999 vs. 2001, 2000 vs. 2002, 2001 vs. 2003, and 2002 vs. 2004), so there are seven degrees of freedom for the t-test. Some average differences of the top and bottom groups may not equal the difference of the averages for the groups due to rounding.  N/A denotes "Not Applicable."
