What is the test for awarding attorneys' fees in a personal injury action?

We apply a two-part test to determine whether the district court abused its discretion. In awarding attorneys' fees, the courts must first calculate a lodestar amount by multiplying the number of hours reasonably expended on the litigation by a reasonable hourly rate. Id. at 433. Next, the court may increase or reduce the presumptively reasonable lodestar fee. Clark v. City of Los Angeles, 803 F.2d 987, 991 (9th Cir.1986).
