 As provided in the Partnership Agreement, as amended (the
 &amp;#x201C;Amended Partnership Agreement&amp;#x201D;), a first right of
 presentment valuation was computed during the first quarter of
 2015. The per-unit value was determined to be $9,765 based on the
 valuation date of December&amp;#xA0;31, 2014. A second right of
 presentment valuation was computed during October 2015 and the
 per-unit value was determined to be $9,831 based on a valuation
 date of June&amp;#xA0;30, 2015. The Partnership did not repurchase any
 Investing Partner Units (Units) during the first nine months of
 2015, and is not expected to purchase any Units in the fourth
 quarter of 2015. The per-unit right of presentment value computed
 during the first quarter of 2014 was determined to be $16,020 based
 on the valuation date of December&amp;#xA0;31, 2013, and the second
 per-unit right of presentment in 2014 was $16,260 based on a
 valuation date of June&amp;#xA0;30, 2014. The Partnership did not
 repurchase any Units during the first nine months of 2014. 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.&lt;/p&gt;

 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. On July&amp;#xA0;9, 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&amp;#xA0;15, 2017. 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.&amp;#xA0;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.&lt;/p&gt;

 recurring basis in the Partnership&amp;#x2019;s consolidated balance
 sheet. As of September&amp;#xA0;30, 2015, and December&amp;#xA0;31, 2014,
 the carrying amounts of the Partnership&amp;#x2019;s current assets and
