O’Melveny & Myers’ sole resident Singapore partner Nathan Bush has left the firm to join DLA Piper.

Bush joins as the firm’s Singapore-based Asia head of investigations and Asia head of antitrust. A disputes specialist, Bush focuses his practice on investigations and regulatory compliance issues with an emphasis on antitrust law. He joined the firm in 2001 and became a partner in 2009. With a focus on China-related work, Bush was based in the firm’s Beijing office between 2004 and 2012, at which time he started to split his time between the Chinese capital and Singapore.

In late 2015, Bush became the only partner who is primarily based in the Singapore office—after capital markets partner Andrew Hutton decided to relocate to Hong Kong to be closer to clients. Before that, in early 2014, Bush changed his primary residence from Beijing to Singapore, where the firm would lose more than a dozen senior lawyers in the following two years.

The departures included three former Singapore partners: disputes partner Dean Collins left to open a Singapore office for Dechert in early 2014, and restructuring partners Bertie Mehigan and Joel Hogarth left for Ashurst later that year. Both have moved on from the British firm.

In 2014, The Asian Lawyer reported that ex-O’Melveny partners cited management’s lack of understanding of Asian clients’ unique needs for flexible fee arrangements, and the firm’s emphasis on disputes work as reasons for leaving. O’Melveny chairman Brad Butwin denied both claims and maintained that the firm focused more on connecting its Asia practice with the U.S. practice than growing headcounts in individual offices. In October, our most recent Asia 100 survey found that in 2015, O’Melveny’s 53 Asia lawyer headcount was less than half the 114 lawyers it reported five years ago.

The exits spread into Hong Kong this year when the former office head—international arbitration partner Friven Yeoh—left for Sidley Austin with two counsel.

DLA Piper is also home to several ex-O’Melveny lawyers. Most recently, the firm in December hired Hong Kong-based restructuring partner Andrew Payne, who reunited with two of his O’Melveny colleagues—Mark Fairbairn and Ashley Bell. Both Fairbairn and Bell joined DLA in early 2014.

In June 2016, former O’Melveny Shanghai managing partner Li Qiang also defected to DLA Piper alongside former counsel Stewart Wang, who became a partner at his new firm.

In Singapore, O’Melveny now is left with two associates Ning Qiao, who moved to the city-state from Beijing with Bush, and Wincen Santoso, an Indonesia-qualified disputes lawyer who had worked closely with Bush. According to its website, Hong Kong partner Andrew Hutton and Menlo Park partner David Makarechian both spend time in Singapore.

“We remain committed to serving clients in Singapore and throughout southeast Asia, not only from our Singapore office, but from our other offices in Asia and worldwide,“ an O’Melveny spokeswoman said in a statement. “We have several lawyers who travel regularly to Singapore, and we will continue the same high quality and level of international advice we have been providing to our clients operating in Singapore.“
