What is the test for determining the amount of victim restitution in a sexual assault case?

"At the core of the victim restitution statutory scheme is the mandate that a victim who suffers economic loss is entitled to restitution and that the restitution is to be 'based on the amount of loss claimed by the victim.' Thus, a victim seeking restitution . . . initiates the process by identifying the type of loss ( 1202.4, subd. (f)(3)) he or she has sustained and its monetary value." (People v. Fulton (2003) 109 Cal.App.4th 876, 885-886.) Once the victim makes a prima facie showing of economic losses incurred as a result of the defendant's criminal acts, the burden shifts to the defendant to disprove the amount of losses claimed by the victim. (Id. at p. 886.) "This approach complies with the statutory mandate that the amount of restitution is to be based on the 'loss claimed by the victim' and the designated right of the defendant to a hearing 'to dispute the determination of the amount of restitution.' " (Ibid.)
