Former colleague running against Philadelphia's prosecutor

ALTOONA, Pa. (AP) — The University of Pittsburgh Medical Center has filed a lawsuit against a Cleveland firm, alleging that an actuarial employee vastly understated the pension liability of the hospital that's now UPMC Altoona. The Altoona Mirror reports (http://bit.ly/2dk9Fhh ) UPMC filed the lawsuit against CBIZ Inc. in federal court last week. UPMC says in the lawsuit that it wouldn't have acquired Altoona Regional Health System in 2013 had it known the hospital's full liability. The lawsuit says the liability was $123 million more than what was stated in pension documents. The lawsuit names CBIZ and its now-retired, Maryland-based actuary, Jon Ketzner, as defendants. UPMC is seeking $142 million in damages, plus punitive damages. CBIZ says it plans to vigorously contest the allegations. Ketzner referred a request for comment to CBIZ. ___ Information from: Altoona Mirror, http://www.altoonamirror.com
