A week after welcoming back former technology partner Rezwan Pavri in Silicon Valley, Wilson Sonsini Goodrich & Rosati has recruited Munger, Tolles & Olson corporate and securities partner Katherine Ku in Los Angeles.

Ku, who made partner at her former firm in 2013, was partner of a Munger Tolles team that advised longtime client Berkshire Hathaway Inc. on its $4.7 billion buy of Duracell from The Procter & Gamble Co., a transaction that was completed last year. Ku also advised Internet Brands Inc.—owner of Lawyers.com—on its $1.1 billion sale in 2014 to private equity giant KKR & Co. LP.
