The Oslo Stock Exchange (OSE) has launched a robust defence of its operations as it faces losing two big shipping names this year.

Greece's Star Bulk Carriers said in April it was scrapping its Oslo listing due to a lack of trading volumes, while US-based Team Tankers International said it has shareholder support for a delisting.

It also blamed liquidity, as well as the fact that its low valuation made it difficult to pursue mergers, acquisitions and sale and purchase deals.
