UBS Group AG is looking to retain more than 100 Credit Suisse Group AG investment bankers across Asia, as the Swiss banking giant plans to shore up talent in markets where its rival has a stronger presence, Bloomberg News reported on Sunday.

The bank is currently in advanced discussions to keep dozens of Credit Suisse's senior dealmakers in countries including South Korea, Thailand, Vietnam, and India following a planned takeover, the report said, citing people familiar with the matter.

Bloomberg said that Switzerland's biggest bank's retention target of more than 100 bankers did not include China. It has held talks with a few bankers in China, but the final number being kept will depend on discussions with regulators, the report added.

UBS and Credit Suisse did not immediately respond to emailed requests for comment.

Reuters last month reported that hundreds of Credit Suisse employees are resigning each week in a sign of uncertainty gripping the lender while it is being taken over by its larger rival.

UBS Chief Executive Sergio Ermotti on Friday warned of painful decisions about job cuts following the takeover, which he said he hoped would be formalized in the coming days.
