Use of Estimates | |
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates with regard to these financial statements include the estimate of proved oil and gas reserves and related present value estimates of future net cash flow therefrom and asset retirement obligations. Actual results could differ from those estimates. |

3 | RIGHT OF PRESENTMENT | |
As provided in the Partnership Agreement, as amended (the “Amended Partnership Agreement”), a first right of presentment valuation was computed during the first quarter of 2013. The per-unit value was determined to be $15,412 based on the valuation date of December 31, 2012. A second right of presentment valuation was computed during October 2013 and the per-unit value was determined to be $15,622 based on a valuation date of June 30, 2013. The Partnership did not repurchase any Investing Partner Units (Units) during the first nine months of 2013, as a result of the Partnership’s limited amount of cash available for discretionary purposes, and is not expected to purchase any Units in the fourth quarter of 2013. The per-unit right of presentment value computed during the first quarter of 2012 was determined to be $15,516 based on the valuation date of December 31, 2011, and the second per-unit right of presentment in 2012 was $15,932 based on a valuation date of June 30, 2012. The Partnership did not repurchase any Units during the first nine months of 2012. Pursuant to the Amended Partnership Agreement, the Partnership has no obligation to purchase any Units presented to the extent it determines that it has insufficient funds for such purchases. |
