Under this method of accounting, all costs incurred for both successful and unsuccessful exploration and development activities, and oil and gas property acquisitions are capitalized. The net book value of oil and gas properties may not exceed a calculated “ceiling.” The ceiling limitation is the estimated future net cash flows from proved oil and gas reserves, discounted at 10 percent per annum. Estimated future net cash flows are calculated using end-of-period costs and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements. For a discussion of the calculation of estimated future net cash flows, please refer to Note 10-Supplemental Oil and Gas Disclosures to the consolidated financial statements contained in the Partnership’s Annual Report on Form 10-K for the fiscal year ended </font><font style="font-family:inherit;font-size:10pt;">December 31, 2015</font><font style="font-family:inherit;font-size:10pt;">.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Any excess of the net book value of proved oil and gas properties over the ceiling is charged to expense and reflected as “Additional depreciation, depletion and amortization” in the accompanying statement of consolidated operations. Such limitations are tested quarterly.</font></div></div>

The new standard removes inconsistencies in existing standards, changes the way companies recognize revenue from contracts with customers, and increases disclosure requirements. The guidance requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB announced a delay in the effective date of the revenue standard by one year. The deferral results in the new revenue standard becoming effective for annual and interim periods beginning after December 15, 2017. In March 2016, the FASB issued ASU 2016-08, which provides further clarification on the principal versus agent evaluation. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the opening balance sheet. The Partnership is currently evaluating the level of effort needed to implement the standard, the impact of adopting this standard on its consolidated financial statements, and whether to use the full retrospective approach or the modified retrospective approach.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div></div>

The per-unit right of presentment value computed during the first quarter of </font><font style="font-family:inherit;font-size:10pt;">2015</font><font style="font-family:inherit;font-size:10pt;"> was determined to be $</font><font style="font-family:inherit;font-size:10pt;">9,765</font><font style="font-family:inherit;font-size:10pt;"> based on the valuation date of </font><font style="font-family:inherit;font-size:10pt;">December 31, 2014</font><font style="font-family:inherit;font-size:10pt;">.

Significant estimates with regard to these financial statements include the estimate of proved oil and gas reserve quantities and the related present value of estimated future net cash flows therefrom and the assessment of asset retirement obligations. Actual results could differ from those estimates.</font></div><div style="line-height:120%;padding-top:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;text-decoration:underline;">Oil and Gas Property</font></div><div style="line-height:120%;padding-top:8px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Partnership follows the full-cost method of accounting for its oil and gas property. Under this method of accounting, all costs incurred for both successful and unsuccessful exploration and development activities, and oil and gas property acquisitions are capitalized. The net book value of oil and gas properties may not exceed a calculated “ceiling.” The ceiling limitation is the estimated future net cash flows from proved oil and gas reserves, discounted at 10 percent per annum. Estimated future net cash flows are calculated using end-of-period costs and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements. For a discussion of the calculation of estimated future net cash flows, please refer to Note 10-Supplemental Oil and Gas Disclosures to the consolidated financial statements contained in the Partnership’s Annual Report on Form 10-K for the fiscal year ended </font><font style="font-family:inherit;font-size:10pt;">December 31, 2015</font><font style="font-family:inherit;font-size:10pt;">.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Any excess of the net book value of proved oil and gas properties over the ceiling is charged to expense and reflected as “Additional depreciation, depletion and amortization” in the accompanying statement of consolidated operations. Such limitations are tested quarterly. In the </font><font style="font-family:inherit;font-size:10pt;">first</font><font style="font-family:inherit;font-size:10pt;"> quarter of </font><font style="font-family:inherit;font-size:10pt;">2016</font><font style="font-family:inherit;font-size:10pt;">, the Partnership recorded a </font><font style="font-family:inherit;font-size:10pt;">$1,271,885</font><font style="font-family:inherit;font-size:10pt;"> non-cash write-down of the carrying value of its proved oil and gas properties.</font></div><div style="line-height:120%;padding-top:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;text-decoration:underline;">New Pronouncements Issued But Not Yet Adopted</font></div><div style="line-height:120%;padding-top:8px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2014, the Financial Accounting Standards Board (FASB) and the International Accounting Standards Board (IASB) issued a joint revenue recognition standard, ASU 2014-09. The new standard removes inconsistencies in existing standards, changes the way companies recognize revenue from contracts with customers, and increases disclosure requirements. The guidance requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. In July 2015, the FASB announced a delay in the effective date of the revenue standard by one year. The deferral results in the new revenue standard becoming effective for annual and interim periods beginning after December 15, 2017. In March 2016, the FASB issued ASU 2016-08, which provides further clarification on the principal versus agent evaluation. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the opening balance sheet. The Partnership is currently evaluating the level of effort needed to implement the standard, the impact of adopting this standard on its consolidated financial statements, and whether to use the full retrospective approach or the modified retrospective approach.</font></div></div>
