Recent Accounting Pronouncements	(18) Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments- Credit Losses (“ASC Topic 326”): Measurement of Credit Losses on Financial Instruments. The amendment in ASC Topic 326 require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. The amendments in this update are effective for interim and annual periods beginning after January 1, 2020, with early adoption permitted by one year. We plan to adopt this new standard on January 1, 2020 and expect that our adoption of this standard will not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASC Topic 842 Leases (“ASC Topic 842”). ASC Topic 842 is a new leasing standard that increases transparency and comparability among organizations by, among other things, requiring lessees to recognize most lease assets and lease liabilities on the balance sheet and requiring both lessees and lessors to disclose expanded qualitative and quantitative information about leasing arrangements. ASC Topic 842 becomes effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption of this standard is permitted. In March 2018, the FASB approved amendments to ASC Topic 842 which allow the additional transition method of using the effective date as the date of initial application, as compared to the beginning of the earliest period presented, and recognize a cumulative-effect adjustment to the beginning balance of retained earnings as of the effective date. We adopted this new standard on January 1, 2019 and plan to use the current period adjustment method. Upon adoption, we will recognize the cumulative effect of adoption as an adjustment to the opening balance of our partners’ capital. Comparative information will continue to be reported under the accounting standards in effect for those periods. Additionally, in July 2018, the FASB approved amendments to ASC Topic 842 (the “July 2018 amendment”) which provided lessors with a practical expedient to not separate non-lease components from the associated lease component and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under ASC Topic 606 and certain conditions are met. The July 2018 amendment also provided clarification on whether ASC Topic 842 or ASC Topic 606 is applicable to the combined component based on determination of the predominant component. An entity that elects the lessor practical expedient also should provide certain disclosures. We have evaluated the impact of the July 2018 amendment on our contract operations services agreements and have concluded that the services non-lease component is predominant, which would result in the ongoing recognition of revenue following ASC Topic 606 guidance. We have completed the collection of our lease data for the effective date and are using information technology tools to assist in our continuing lease data collection and analysis. We are updating our accounting policies and internal controls that are impacted by the new guidance. We do not believe the standard will materially affect our consolidated balance sheets, statements of operations or cash flows. Our preliminary estimate of the impact of recording lease assets and lease liabilities on our consolidated balance sheet upon adoption does not exceed $4.0 million, with no material impact to our consolidated statements of operations. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (“ASC Topic 820”): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The amendments to ASC Topic 820 eliminate, add and modify certain disclosure requirements for fair value measurements as part of the FASB’s disclosure framework project. The amendments in this update are effective for interim and annual periods beginning on January 1, 2020, with early adoption permitted. We are currently evaluating the impact, if any, of the amendments to ASC Topic 820 on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (“ASC Subtopic 350-40”): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments to ASC Subtopic 350-40 align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments to ASC Subtopic 350-40. The amendments in this update are effective for interim and annual periods beginning on January 1, 2020, with early adoption permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are currently evaluating the impact, if any, of the amendments to ASC Subtopic 350-40 on our consolidated financial statements.
