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 condensed 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, 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.
Goodwill	Goodwill: Ferrellgas completed its most recent annual goodwill impairment test on January 31, 2020 and did not incur an impairment loss.
New accounting standards	(3) New accounting standards: 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 became effective for Ferrellgas for its annual reporting period beginning August 1, 2019, including interim periods within that reporting period. Ferrellgas adopted the standard using 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, to continue to report comparative periods in compliance with the prior guidance (ASC 840). Ferrellgas elected the short-term lease recognition exemption for all leases that qualify, meaning it does not recognize right-of-use assets or lease liabilities for those leases. Ferrellgas also elected the practical expedient to not separate lease and non-lease components for its most significant leasing activity, which includes vehicle and real estate leases. Additionally, Ferrellgas elected the package of three practical expedients which allows entities to not reassess initial direct costs, lease classification for existing or expired leases, and lease definition for existing or expired contracts as of the effective date of August 1, 2019. Ferrellgas did not, however, elect the hindsight method practical expedient which would have allowed it to reassess lease terms and impairment. 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 plans to adopt the amended guidance effective August 1, 2020. Ferrellgas does not expect this adoption to have a material impact 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 became effective for Ferrellgas for its annual reporting period beginning August 1, 2019, including interim periods within that reporting period. Ferrellgas applied ASU No. 2017-12 using a modified retrospective approach for cash flow hedges existing at the date of adoption and prospectively for the presentation and disclosure guidance. The adoption of this standard did not have a material impact on our consolidated financial statements.
