It’s been a busy time for Cleary Gottlieb Steen & Hamilton lately. The firm worked on the largest M&A deal of the week last week, and it’s one of a few firms representing Credit Suisse in its $4.6 billion acquisition by competitor UBS.

Cleary’s involvement in both the largest deal of the week as well as a rescue transaction for Credit Suisse illustrates exactly how some law firms’ corporate departments are staying busy, despite a general slowdown in M&A since last year.
