Tethys Oil’s revenue amounted during the fourth quarter 2015 to MSEK 222. Tethys Oil’s share of the production, before government take, from Blocks 3 and 4 onshore the Sultanate of Oman amounted in the fourth quarter to 997,904 barrels. The average achieved oil price during the quarter was USD 47.9 per barrel. All oil sales relate to Blocks 3 and 4 in Oman, where Tethys Oil holds 30 per cent of the licence. As per the fourth quarter 2015, Tethys Oil has changed its accounting principles with regard to valuation of underlift and allocation and presentation of over- and underlift. The purpose of the change is to better align Revenue with the production development, have a more understandable Operating expenses category and thereby increase transparency and investors’ understanding of the company. Both over- and underlift will, starting from the fourth quarter 2015, be valued at market value, whereas the previous accounting principles valued overlift to market price and underlift at cost. Both over- and underlift will be presented within Revenue instead of within Operating expense as was the previous accounting principle. As per the new accounting principles Revenue will be aligned and follow the production performance during the reporting period. There will be no changes to effects on operating result or net result with regard to overlift. The change in valuation will for individual quarters have an impact in case of underlift following the change in valuation to market value. The change in accounting principles will however over time have no impact. Historic financial data has been recalculated in line with the new accounting principles. | Tethys Oil’s share Blocks 3 and 4 | Net sales (MSEK) | Over-/underlift adjustment (MSEK) | Revenue (MSEK) | Average oil price (USD/bbl) | Net sales (bbl)\* | Over-/underlift (bbl)\*\*\* | Production (bbl)\*\* | | Q4 2015 | 151 | 70 | 222 | 47.9 | 366,746 | 22,725 | 997,904 | | Q3 2015 | 307 | -52 | 255 | 61.8 | 584,399 | -129,439 | 918,474 | | Q2 2015 | 265 | -42 | 223 | 57.8 | 545,019 | -22,647 | 848,939 | | Q1 2015 | 163 | 41 | 205 | 63.8 | 308,892 | 80,924 | 774,315 | | Q4 2014 | 310 | -29 | 281 | 97.1 | 434,035 | -12,828 | 757,730 | | Full year 2015 | 886 | 18 | 905 | 58.1 | 1,805,056 | 22,725 | 3,539,631 | | Full year 2014 | 1,046 | -19 | 1,027 | 103.9 | 1,464,228 | -12,828 | 2,765,654 | \* After government take \*\* Before government take \*\*\* Volumes sold has not always correspond to Tethys Oil’s share of production after government take during a period.
