One Man Two Hats: What's All the Commotion!

We examine performance in publicly listed U.K. companies over a period that encompasses the issuance of the Cadbury Committee's Code of Best Practice, which calls for the abolition of the combined CEO/COB position. We find that companies splitting the combined CEO/COB position to conform to the Code's requirement did not exhibit any absolute or relative improvement in performance when compared to various peer‐group benchmarks. We do not necessarily scoff at mandated board structures, but the evidence suggests that this particular legislature coerced the abandonment of the combined CEO/COB position and appears to be wide of the mark.
