There is a lot of debt though, so the low PE in perspective.... Why do you think the out performance will continue? Didn't most of the growth in EPS come from the acquisition in the UK? read the full year report a few months ago so can't really remember.
The purchase of WM Shipping did not have a negative effect as calculations were according to FTSE rules.They have very good management team . For safety of course good to have alerts on this share and to watch the Regression Line. It is likely to fall back some now being ex-div.
