Swedish tanker and ferry giant Stena AB has more than $2bn for potential acquisitions as it faces up to a tough 2017.

CEO Dan Sten Olsson said in the company's annual report that the SEK 19.1bn ($2.16bn) of available cash, unused credit facilities and financial assets provides a "good cushion" in difficult times.

And he added: "It might also be used for strategic acquisitions would the opportunity arise."
