Norway's Color Line saw its annual result drop into the red in 2020 as a result of Covid-19 restrictions on passenger shipping.
Color Group, the privately-owned ferry operator's Norwegian holding company, reported a pre-tax loss of NOK 1.198bn ($139m) against a profit of NOK 274m a year earlier.
The company said passenger traffic on Color Lines' ferries to Germany, Denmark and Sweden was reduced by nearly 70%.
