Singapore's BW Group has sold off a block of BW LPG stock worth $41.6m to increase the daughter company's free float of shares.

The parent group had signalled on Wednesday that up to 7m shares could be sold in Oslo, but after the announcement it decided to offload only 5.8m.

This was "in order to retain flexibility and stay above the 40% mandatory offer threshold", BW LPG said.
