It is fast becoming an imperative for elite firms to widen the range of their partner compensation. Too narrow a range allows competitors with wider ranges to lure away the most commercially successful partners. We saw this in London when the U.S. firms arrived and undid the elite London firms’ lockstep models. We are seeing this increasingly in New York where firms like Kirkland & Ellis, who reportedly moved recently to a ratio of the compensation of their highest- to lowest-compensated partners of 9-1, pose a renewed threat to old-line firms with narrow, 3-1-type ratios.

There are a number of reasons to believe that a compensation range of about 9-1 is consistent with the range in economic contribution of individual partners’ practices and is thus the range a firm’s compensation must reflect to avoid having its partners be cherry picked by others. One is that 9-1 is consistent with what I’ve seen at elite professional services firms as a consultant—the rule of thumb I had developed was that newly-promoted (and hence lowest-comped) partners earned about one-third of firm average while the most commercially productive partners receive three times firm average—from one-third to three times firm average is a 9-1 ratio of top to bottom. I should note that here, and in what follows, the ratio I refer to is that between the average compensation of the top and bottom deciles of partners by compensation, and not of the highest- and lowest-compensated individual partners.
