Restated first quarter 2014 accounts

This report replaces the first quarter financial reporting announced by Det norske oljeselskap ASA on 30 April 2014. The reissuance of these condensed interim financial statements has been triggered by a rights offering involving the preparation of a prospectus in connection to the acquisition of Marathon Oil Norge AS, including an ISRE 2410 limited review performed by the Company's independent auditor.

As a result, the Company evaluated events subsequent to the original approval date of 30 April 2014 by the Board of Directors of the Q1 2014 interim financial statements for new information that, if known at the original approval date, would have resulted in adjustments to the financial statements and for other information that would have resulted in additional disclosures. These events have been considered through the date of this report. Subsequent events which have occurred since 30 April 2014 that have resulted in additional disclosures are described in note 21 in the attached report. There has been one matter which has resulted in the recognition of an impairment charge on the Jette field, during the three months ended 31 March 2014, as described in note 4 in the attached report.
