This ASU amends the consolidation requirements in ASC 810 and significantly changes the consolidation analysis required under US GAAP.

In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ASU No. 2014-15, “Presentation of Financial Statements-Going Concern”. ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The Partnership is still evaluating the impact of this pronouncement on the condensed consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606). ASU 2014-09 supersedes the revenue recognition guidance in Topic 605, Revenue Recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in the exchange for those goods or services. This standard is effective for annual reporting periods beginning after December 15, 2016. The Partnership is still evaluating the impact of this pronouncement on the condensed consolidated financial statements.
