The market proxy used is the FT All Share Index ; we also examine for comparative purposes the impact of using a broader based market index. Returns on both individual companies and the market are measured as log excess returns over the safe rate, with base rates used as the proxy for the safe rate, converted appropriately for the relevant frequency (see Appendix for details of data and estimation results).
