The European derivatives exchange launched by Nasdaq in 2013 continued to struggle last year, with losses since inception totalling well over half of its parent's near-£60 million investment.

Nasdaq NLX posted pre-tax losses of £16.5 million in 2014, compared with losses of £17.6 million in 2013, according to accounts filed with the UK's Companies House on September 10. Total losses since its inception have reached £39.2 million, the accounts show, against investment of £56 million by the exchange group.
