It seems from following paragraph in recent article in regard to DUANE MORRIS business plan, the large portion of $18 to $20 million dollar will be spent on EDIG contingent fee work( just for 2008).

Duane Morris' program devotes 4 percent of the firm's billable time to contingent fee work. For the firm's expected $450 million in total recorded time for 2008, Bonovitz said that would mean about $18 million to $20 million in time spent on those matters.

AND DONT FORGET FOLLOWIN PARAGRAPH ALSO !

The firm will only take large commercial cases with a minimum fee of $1 million. There must be a 75 percent probability of success as determined by the firm's attorneys and contingent fee committee, and an opportunity to get three times the firm's recorded time.
