The merger between Buchanan Ingersoll and Klett Rooney Lieber & Schorling could vault the firm into the Am Law 100 this year with Buchanan Ingersoll & Rooney showing a 40 percent increase in gross revenue during 2006 compared with Buchanan Ingersoll’s pre-merger numbers in 2005.

The firm, which completed the large-scale merger in July, saw its revenue jump from $193.7 million in 2005 to $271.3 million in 2006. That figure is slightly more than the firm’s prediction of $265 million at the time of the merger.
