Results of Operations for Producing Activities
The following schedule sets forth the revenues and expenses related to the production and sale of oil and gas. The income tax expense is calculated by applying the current statutory tax rates to the revenues after deducting costs, which include depreciation, depletion and amortization allowances, after giving effect to the permanent differences. The results of operations exclude general office overhead and interest expense attributable to oil and gas production.

Oil and Gas Reserves (Unaudited)
The following table presents estimated volumes of proved developed and undeveloped oil and gas reserves as of December 31, 2012, 2011 and 2010 and changes in proved reserves during the last three years. The reserve reports use an average price equal to the unweighted arithmetic average of hydrocarbon prices received on a field-by-field basis on the first day of each month within the 12-month period ended December 31, 2012, 2011 and 2010, in accordance with guidelines of the SEC applicable to reserves estimates. Volumes for oil are stated in thousands of barrels (MBbls) and volumes for gas are stated in millions of cubic feet (MMcf). The prices used for the 2012 reserve report are $91.32 per barrel and $2.76 per MMbtu, adjusted by lease for transportation fees and regional price differentials, and for oil and gas reserves, respectively. The prices used at December 31, 2011 and 2010 for reserve report purposes are $96.19 per barrel and $4.12 per MMbtu and $76.16 per barrel and $4.38 per MMbtu, respectively.
Gulfport emphasizes that the volumes of reserves shown below are estimates which, by their nature, are subject to revision. The estimates are made using all available geological and reservoir data, as well as production performance data. These estimates are reviewed annually and revised, either upward or downward, as warranted by additional performance data.

The Company contributed its Permian Basin assets to Diamondback in 2012, as discussed in Note 4, resulting in a decrease of 12,564 thousand barrels of oil equivalent (MBOE) in estimated proved reserves in 2012. In addition, the Company experienced downward reserve revisions of 442 MBOE in estimated proved reserves in 2012 primarily due to a change in the drilling schedule of its Niobrara acreage. The Company also experienced downward reserve revisions in 2011. These downward revisions were primarily the result of the drilling of PUDs during the Company’s 2011 drilling program and ethane takeaway issues in the Permian Basin. The Company experienced downward reserve revisions in estimated proved reserves in 2010. These downward revisions were primarily the result of the five-year schedule for proved undeveloped reserves from the SEC’s “Modernization of Oil and Gas Reporting” Final Rule.
Discounted Future Net Cash Flows (Unaudited)
The following tables present the estimated future cash flows, and changes therein, from Gulfport’s proven oil and gas reserves as of December 31, 2012, 2011 and 2010 using an unweighted average first-of-the-month price for the period January through December for 2012, 2011 and 2010.
