A federal judge has given final approval to a $4 million class settlement in a case that alleged mortgage holders were charged excessive premiums in captive reinsurance arrangements by various progeny of Washington Mutual.

All factors weighed in favor of the settlement, U.S. District Judge Thomas N. O’Neill Jr. of the Eastern District of Pennsylvania said in his opinion issued this week in Alexander v. Washington Mutual. He also approved the $1.2 million sought in attorney fees.
