Oil major BP (BP.) falls 1.6% to 466p as it announces a year-on-year decline of 21.6% in replacement cost profit for 2013 to £8.2 billion. The metric, which strips out one-off gains and the impact of commodity prices, was hit by weak refining margins, higher exploration write-offs and asset sales. A rare bright spot in the numbers was provided by the reserves replacement ratio (measuring the extent to which the company replaces reserves lost to production) which recovers from last year's 77% to 129%. There is no material update on the group's Gulf of Mexico oil spill related liabilities.


Its peer BG (BG.) gains 2.9% to £10.55 as it reports a $1.08 billion loss in the last three months of 2013 against a profit of $1.76 billion for the same period in 2014. The rise may reflect some relief that performance was in-line with the guidance given in last week's profit warning.
