NOTES TO STATEMENT OF
REVENUES AND DIRECT OPERATING EXPENSES
NOTE 1—BASIS OF PRESENTATION
On November 17, 2011 Energy Partners, Ltd., (“EPL”) acquired, from Stone Energy Offshore, L.L.C. (“Stone”), a subsidiary of Stone Energy Corporation, an asset package consisting of certain offshore oil and gas properties located in the Gulf of Mexico (the “Properties”) as defined in the Purchase and Sale Agreement dated as of October 28, 2011, between EPL and Stone for approximately $38.6 million, subject to customary closing adjustments, with an effective date of November 1, 2011. The accompanying statements of revenues and direct operating expenses (the “Statements”) relate to the operations of the oil and gas properties acquired by EPL.
The statements of revenues and direct operating expenses associated with the Properties were derived from Stone’s accounting records. During the periods presented, the Properties were not accounted for or operated as a consolidated entity or as a separate division by Stone. Revenues and direct operating expenses for the Properties included in the accompanying statements represent the net collective working and revenue interests to be acquired by EPL. The revenues and direct operating expenses presented herein relate only to the interests in the producing oil and natural gas properties which were acquired and do not represent all of the oil and natural gas operations of Stone, other owners, or other third party working interest owners. Direct operating expenses include lease operating expenses, major maintenance costs and production taxes. Indirect general and administrative expenses, depreciation, depletion and amortization of oil and gas properties and federal and state income taxes have been excluded from direct operating expenses in the accompanying statements of revenues and direct operating expenses because the allocation of such expenses would be arbitrary and would not be indicative of what such costs would have been had the Properties been operated as a stand alone entity. Stone accounted for the Properties under the full cost method of accounting for oil and gas activities. Accordingly, exploration expenses and dry hole costs are not applicable to this presentation. Full separate financial statements, including statements of financial position, results of operations, owners’ equity and cash flows, prepared in accordance with accounting principles generally accepted in the United States of America do not exist for the Properties and are not practicable to prepare in these circumstances. Accordingly, the historical statements of revenues and direct operating expenses of the Properties are presented in lieu of the financial statements required under Rule 3-05 of the U.S. Securities and Exchange Commission (“SEC”) Regulation S-X. The statements of revenues and direct operating expenses presented are not indicative of the results of operations of the Properties on a go forward basis due to changes in the business and the omission of various operating expenses as described above.
NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Revenue Recognition: Revenues in the Statements reflect the entitlement method of accounting for oil and natural gas revenue, recognizing as revenues only the net interest share of all production sold. Amounts attributable to the sale of production in excess of or less than the Properties net interest are excluded from revenues.
Use of Estimates: The preparation of statements of revenues and direct operating expenses in conformity with accounting principles generally accepted in the United States of America requires the use of estimates and assumptions that affect the reported amounts of revenues and direct operating expenses during the reporting period. Actual results may differ from those estimates.
NOTE 3—SUBSEQUENT EVENTS
Management of Stone has evaluated events subsequent to December 31, 2010 through the date of issuance of these statements of revenues and direct operating expenses on January 26, 2012.
NOTE 4—SUPPLEMENTARY OIL AND GAS INFORMATION (UNAUDITED)
Estimated Net Quantities of Oil and Natural Gas Reserves
The following are estimates of the net proved oil and natural gas reserves of the Properties located entirely within the United States of America. Reserve volumes and values were determined under definitions and guidelines of the SEC and, with the exception of the exclusion of future income taxes, conform to the Financial Accounting Standards Board Accounting Standards Codification Topic 932, Extractive Activities-Oil and Gas. Reserve estimates are inherently imprecise and estimates of new discoveries are more imprecise that those of producing oil and gas properties. Accordingly, reserve estimates are expected to change as additional performance data becomes available.
Estimated quantities of proved domestic oil and gas reserves and changes in quantities of proved developed reserves in thousands of barrels (“MBbls”), millions of cubic feet (“MMcf”) for the Properties were as follows:
| | | | | | | | |
| | Oil (MBbl) | | | Natural Gas (MMcf) | |
Proved reserves as of December 31, 2008 | | | — | | | | — | |
Production | | | (186 | ) | | | (127 | ) |

Discounted Future Net Cash Flows
A summary of the discounted future net cash flows related to proved oil and natural gas reserves is shown below. Future net cash flows calculated at December 31, 2010 and 2009 are based on the 12-month unweighted arithmetic average of the first-day-of-the-month price for each month within the 12-month prior period. Future net cash flows calculated at December 31, 2008 were computed using year-end commodity prices that relate to the Properties’ existing oil and natural gas reserves. The oil and natural gas reserves of the Properties were not economical using year-end commodity prices at December 31, 2008; as a result, no proved reserves are presented at December 31, 2008. Commodity prices used in determining future cash flows for and oil and natural gas were $75.96 per barrel and $4.38 per Mcf, respectively, for 2010, and $59.57 per barrel and $3.94 per Mcf, respectively, for 2009.
The discounted future net cash flows, before consideration of federal and state income taxes (see Note 1), related to proved oil and gas reserves are as follows (in thousands):
