What is the test for assessing attorney fees?

Moses, 24 Cal.4th 1122, 1131 (2001). "[A] court assessing attorney fees begins with a touchstone or lodestar figure, based on the 'careful compilation of the time spent and reasonable hourly compensation of each attorney ... involved in the presentation of the case." Id. at 1131-32. To determine the reasonable number of hours billed, courts are to evaluate the time expended, the nature of and need for the services performed, and the relevant fee records. Hensley v. Eckerhart, 461 U.S. 424, 433-34 (1983).
