Debbie Ho, head of fixed income distribution for Asia at UBS in Singapore, has left the firm. "Debbie has left, after four years, to pursue personal interests," said Mark Panday, spokesman at UBS in Hong Kong. Ho ran a successful and highly-profitable sales team in Asia, which included a mandate for credit derivative products, noted market officials. Prior to UBS she was at JPMorgan in New York and Singapore. Panday said local heads in the regional countries will assume her responsibilities. Ho could not be reached.
