With the end of each quarter comes M&A league tables, law firm merger metrics and big-firm leadership confidence surveys, as well as a look at the Am Law 200 firms that saw their attorney head counts change the most so far in 2015.

As we have done twice before this year, The Am Law Daily crunched the numbers in ALM’s RivalEdge database to determine which firms saw their lawyer count shrink and grow during the first three quarters of 2015. Seeking the most complete data set, we looked at head count data from Jan. 1, 2015, through Oct. 14 of this year, tossing out some outsized percentage changes because of incomplete information.
