Courts have developed several means of reviewing the reasonableness of fee requests in class actions. At the dawn of the class action era, the most frequently used device was the lodestar method, which was developed by this Court in Lindy Brothers Builders, Inc. of Philadelphia v. American Radiator & Standard Sanitary Corp., 487 F.2d 161 (3d Cir. 1973). Under that approach, the court assesses the number of hours that lead counsel reasonably worked, decides the reasonable hourly rate for the lawyers' services, and determines counsel's fee by multiplying the number of hours reasonably worked by the reasonable hourly rate. The Supreme Court has developed an elaborate jurisprudence covering the proper application of the lodestar method, which remains the governing approach for cases governed by fee-shifting statutes.
