According to the firm’s directors’ report “in recent years, the hospital has experienced an increase in the number of privately insured patients using its services, however, it has also experienced a significant reduction in prices from insurers and purchasers, which together with an increase in costs due to medical inflation, has eroded profit margins”.
Operating profit last year declined by 10% from €15.5m to €14m. Interest payable of €1.3m and net finance expense of €250,000 reduced profits to €12.4m. The group paid corporation tax of €1.86m that resulted in a post-tax profit of €10.6m.
The group recorded an actuarial loss of €8.6m on its pension scheme in 2012.
