“…Stock-based compensation (SBC) has become an increasingly significant component of executive reward for UK CEOs, while the level of detail and complexity in the design of the stock-based element of pay has increased considerably since the mid-1980s (e.g. Buck et al, 2003;Conyon and Schwalbach, 2000;Goergen and Renneboog, 2011;Main, Bruce and Buck, 1996;Ozkan, 2011;Renneboog and Zhao, 2011). Recent empirical research documents the widespread use of relative performance evaluation (RPE) in stock-based incentive contracts where CEOs and managers are evaluated on the basis of peer performance and, in particular, the use of performance peer groups in restricted share schemes, performance share plans or long-term incentive plans (LTIPs) (Carter, Ittner and Zechman, 2009;Gong, Li and Shin, 2011).…”
