Christopher Olivia, who stepped down as West Penn Allegheny Health System president and CEO two years ago, was nevertheless the health system's highest compensated employee in the fiscal year ending June 30, 2012, newly released tax documents show. Dr. Olivia received just under $678,000 in base compensation and $2.5 million in bonus and incentive pay, which combined with retirement and other benefits, brought his total compensation to just over $6 million. He resigned in June 2011 after Highmark and WPAHS announced plans to affiliate.
