Mayer Brown JSM has boosted its banking and finance practice in Hong Kong with the recent hire of partner Vincent Sum from Bingham McCutchen.

Sum advises underwriters, arrangers, portfolio managers, issuers and trustees on capital market matters including structured products, derivatives, securitisation retails and non-retail funds.

Sum was the last remaining partner at Bingham McCutchen’s Hong Kong office after corporate specialists Matthew Puhar and Charles Rogers left for Akin Gump Strauss Hauer & Feld in September, as part of a global exodus of 28 partners to the latter firm. Puhar and Rogers were among five partners who joined Akin Gump in Hong Kong from Bingham.

Last year, the besieged Bingham McCutchen was acquired by the Philadelphia-headquartered  Morgan, Lewis & Bockius, which announced that it would accept  most partners from the Boston law firm. However, Morgan Lewis doesn’t have a Hong Kong office.

Mayer Brown JSM has offices in Hong Kong, mainland China, Singapore, Thailand and Vietnam.
