Royal Dutch Shell, the Anglo-Dutch multinational oil firm, reported better-than-expected earnings for its third quarter on Tuesday, but gave a cautious outlook as it continues to struggle in an environment of low oil prices.

Shell's earnings on a current cost of supplies (CCS) basis attributable to shareholders (excluding identified items) reached $1.4 billion in the third quarter, after contracting $6.1 billion in the same period a year ago. CCS is a common accounting measure for commodity-reliant businesses and Shell noted that the increase was due to lower operating costs and increased production.
