“The result was impacted by $2.3 billion in net impairment charges mainly due to reduced long-term price assumptions,” Statoil said in a statement.

The firm maintained its dividend policy and said it would have the same amount of capital expenditure in 2017 than in 2016, or $11 billion, and the same in terms in oil and gas exploration, or $1.5 billion.

Statoil shares are up 31 percent over the past year, beating a European oil and gas index up 24 percent over the same period.
