The Magistrate Judge held that because UPMC did not retain unprotected supervisors from Montefiore, i.e., supervisors under the age of 40, appellant could not satisfy the fourth element, and summary judgment was therefore appropriate. App. at 56-57, 62.

See Keller, 130 F.3d at 1108; see also Healy v. New York Life Ins. Co., 860 F.2d 1209, 1214 n. 1 (3d Cir.1988) (<HOLDING>). Nevertheless, in light of the Supreme Court’s
