Significant Accounting Policies
Accounting estimates	Accounting estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from these estimates. Significant estimates impacting the consolidated financial statements include accruals that have been established for contingent liabilities, pending claims and legal actions arising in the normal course of business, useful lives of property, plant and equipment assets, residual values of tanks, capitalization of customer tank installation costs, amortization methods of intangible assets, valuation methods used to value sales returns and allowances, allowance for doubtful accounts, fair value of reporting units, recoverability of long-lived assets, assumptions used to value business combinations, fair values of derivative contracts and stock-based compensation calculations.
New accounting standards	New accounting standards: FASB Accounting Standard Update No. 2014‑09 In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update ("ASU") 2014‑09, Revenue from Contracts with Customers (“ASU 2014‑09”). The issuance is part of a joint effort by the FASB and the International Accounting Standards Board ("IASB") to enhance financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards ("IFRS") and, thereby, improving the consistency of requirements, comparability of practices and usefulness of disclosures. Upon adoption, Ferrellgas applied ASU 2014‑09 only to contracts that were not completed, referred to as open contracts. Ferrellgas adopted ASU 2014‑09 beginning on August 1, 2018 using the modified retrospective method. This method requires that the cumulative effect of initially applying ASU 2014‑09 be recognized in partner’s deficit at the date of adoption, August 1, 2018. ASU 2014‑09 has not materially impacted Ferrellgas’ consolidated financial statements, and as a result there was no cumulative effect to record as of the date of adoption. Results for reporting periods beginning after August 1, 2018 are presented under ASU 2014‑09, while amounts reported for prior periods have not been adjusted and continue to be reported under accounting standards in effect for those periods. See Note G - Revenue from contracts with customers for additional information related to revenues and contract costs, including qualitative and quantitative disclosures required under ASU 2014‑09. FASB Accounting Standard Update No. 2016‑02 In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The new standard requires lessees to apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. An entity may elect the transition relief option in ASU 2018-11, “Leases: Targeted Improvements” which, among other things, provides entities with an option to recognize the cumulative-effect adjustment from the modified retrospective application to the opening balance of retained earnings in the period of adoption and consequently, continue to report comparative periods in compliance with the prior guidance (ASC 840). Ferrellgas expects to elect this additional transition method. Ferrellgas is continuing to evaluate the impact of its pending adoption of ASU 2016-02 on the consolidated financial statements. Ferrellgas has made significant progress in assessing the impact of the standard and planning for the adoption and implementation. The implementation team has completed initial scoping and is substantially complete in the data gathering process of our current lease portfolio. Ferrellgas is currently performing a completeness assessment over the lease population, analyzing the financial statement impact of adopting the standards, and evaluating the impact of adoption on our existing accounting policies and disclosures. Ferrellgas believes that the adoption of this standard, which will be effective for Ferrellgas August 1, 2019, will result in material increases to right of use assets and lease liabilities on our consolidated balance sheet. FASB Accounting Standard Update No. 2016‑13 In June 2016, the FASB issued ASU 2016‑13, Financial Instruments - Credit Losses (Topic 326) which requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. This standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. Ferrellgas is currently evaluating the impact of its pending adoption of this standard on the consolidated financial statements. FASB Accounting Standard Update No. 2017‑12 In August 2017, the FASB issued ASU 2017‑12, Financial Instruments - Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities which is intended to improve the financial reporting for hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. This standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Ferrellgas is currently evaluating the impact of its pending adoption of this standard on the consolidated financial statements. FASB Accounting Standard Update No. 2018‑15 In August 2018, the FASB issued ASU 2018‑15, Intangibles - Goodwill and Other - Internal-use Software (Subtopic 350‑40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract which is intended to clarify the accounting for implementation costs related to a cloud computing arrangement that is a service contract. This standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Ferrellgas is currently evaluating the impact of its pending adoption of this standard on the consolidated financial statements.
