Herbert Smith is set to lose another Hong Kong capital markets partner with the resignation of Carolyn Sng (pictured) for Fried Frank Harris 
Shriver & Jacobson.

Sng, who is UK-qualified, will join the US firm's local office in the coming months, with a start date yet to be announced.

Her move comes on the heels of the exits of four other capital markets partners from the firm's global practice, all US-qualified, which has taken partner count in the US securities team from nine partners to five 
since July.

Hong Kong US securities partner Melody Chen recently resigned from the firm to join Morrison & Foerster (MoFo), while Asia head of US capital markets John Moore also left the office to join MoFo during the summer.

Meanwhile, two London partners handed in their notice this September, with global capital markets head Jim Wickenden and fellow capital markets partner Adam Wells quitting to join Allen & Overy.

Sng, who sits in Herbert Smith's corporate group, has a practice focused on M&A, restructurings, corporate finance and private equity transactions within a capital markets context.

She joined Herbert Smith as a partner in 2004 and has worked in Hong Kong since 1999. Clients she has worked with in the past include Credit Suisse, JP Morgan and China National Offshore Oil Corporation.

The latest departures come as Herbert Smith puts a potential merger with alliance firms Gleiss Lutz and Stibbe at the heart of its ongoing Project Blue Sky strategy review.

The firm is considering whether it should push for a merger with its longstanding alliance partners, with a Swiss verein structure allowing all three firms to maintain separate profit pools one option under consideration.
