The number of partners that switched firms in 2009 was artificially high, driven by several large firm closures. A full 15% of partner laterals in 2009 came from 4 firm closures. 2010 lacked the high profile closures but had a significant number of partner moves as a result of a few large mergers. The Hogan Lovells merger and the Sonnenschein deal contributed 90 laterals to the yearly total.
