[1] Opera Limited, the Group's parent, was established in 2018. The amount of share capital in the prior period reflects the share capital of the parent at the time of incorporation, as if the share capital was contributed in 2016. In 2019, the amounts of share capital and other paid in capital have been amended by reclassifying amounts between the two equity components.
