he U.S. Federal Deposit Insurance Corporation (FDIC) is preparing to place First Republic Bank (FRC.N) under receivership imminently, a person familiar with the matter said on Friday, sending shares of the lender down nearly 50% in extended trading. The U.S. banking regulator decided the troubled regional lender's position has deteriorated and there is no more time to pursue a rescue through the private sector, the source told Reuters, requesting anonymity because the matter is confidential.
