0541 GMT - BP shouldn't prioritize an immediate increase in shareholder returns, including a resumption of the quarterly buyback, Barclays analyst Lydia Rainforth writes in a note about the British energy major's improving financial outlook. Instead, BP's management should continue to focus on operational execution, she says. Securing the financial and operational performance over the next year is the best way for management to create long-term shareholder value, she says. Once this is done and debt worries are gone, the case for higher returns becomes a lot stronger, she say. Shares closed Monday at 542.90 pence.
