High oil prices are normally expected to stimulate exploration and the development of new oil and gas fields. But over the last few years, financial analysts have focused strongly on shortterm accounting return (RoACE) for benchmarking and valuation, and this has led to high capital discipline...

This paper studies financial statement information from the 50 largest international oil and gas companies during 1992 to 2011 and evaluates their relation to market values. In particular, we examine how this relationship is affected by accounting method choice (successful efforts versus full...
