Cash generation has been resilient over four consecutive quarters, at an average oil price of just under $50 per barrel. This quarter, we generated robust earnings excluding identified items of $3.6 billion, while over the past 12 months cash flow from operations of $38 billion has covered our cash dividend and reduced gearing to 25%.
