Golden State Bancorp Inc. won approval of a settlement of shareholder suits alleging investors didn’t get enough for their shares in a $2.5 billion acquisition of the California thrift by a San Francisco-based financial institution owned by financier Ronald O. Perelman.

Delaware Court of Chancery Chancellor William B. Chandler III approved the disclosure settlement Jan. 7, but chopped $800,000 out of the $1.3 million in fees lawyers for Golden State shareholders sought in the case.
