The plaintiffs further claim that the refund mitigation technique caused Trilegiant to retain an unfair benefit by offering only partial refunds. But as with their failed CUTPA claim, they cannot argue that Trilegiant was unjustly enriched by not refunding additional, legitimate past membership fees to which its customers were not entitled. See, e.g., Berger v. Home Depot USA, Inc., 741 F.3d 1061, 1070 (9th Cir. 2014) (requiring "unjust retention of [a] benefit" as an element of an unjust enrichment claim). CONCLUSION For the foregoing reasons, we hereby AFFIRM the judgment of the district court. In the Matter of: MPM Silicones, L.L.C.
