Struggling German bank Bloomberg reported that Mizuho Financial Group, a Japanese lender, has expressed interest in purchasing Credit Suisse's securitized products division, citing persons familiar with the situation.
Mizuho is one of several prospective purchasers, including private equity firms Centerbridge Partners and Apollo Global Management Inc.
asset management company Pimco, and international investment firm Sixth Street.
Shares of Credit Suisse increased 1% in trading in Zurich but are down 49% for the year.
Credit Suisse has been reorganising its company as a result of a strategic assessment, which it hopes to announce on October 27 along with its third quarter earnings.
It would be premature to comment on any potential outcomes until then, a Credit Suisse spokeswoman said in an email statement.
