Private equity firm J.C. Flowers & Co. LLC and other shareholders of Shinsei Bank Ltd. plan to sell up to 43,535,000 common shares of the Japanese bank in a secondary offering.

The lender said Aug. 8 that the proposed secondary offering would comprise an international offering of 25,783,900 shares, with an overallotment option of up to 3,867,500 shares, and a domestic offering of 13,883,600 shares, with an overallotment option of 2,082,500 shares.

Once the offering is completed, the stake of J.C.

Further, Flowers announced his intention to retire from the bank's board of directors following the completion of the offering.

The offering is expected to be settled between Aug. 27 and Aug. 30, or on the fifth business day following the offering price determination date, the bank added.
