The accompanying Consolidated (Condensed) Financial Statements have been prepared in accordance with Article 10 of Regulation S-X and do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The year-end Consolidated (Condensed) Balance Sheet was derived from the audited financial statements included in Energizer's Report on Form 10-K, but does not include all disclosures required by U.S. GAAP. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of our operations, financial position and cash flows have been included.

As a result of the Varta Divestiture, the assets and liabilities associated with the Divestment Business as of September 30, 2019 were classified as held for sale in the accompanying Consolidated (Condensed) Balance Sheet. There were no assets or liabilities from these operations as of June 30, 2020. The respective operations of the Divestment Business, including the loss recorded on divestment, for the three and nine months ended June 30, 2020 and 2019 have also been classified as discontinued operations in the accompanying Consolidated (Condensed) Statements of Earnings and Comprehensive Income and Consolidated (Condensed) Statements of Cash Flows. Refer to Note 4, Divestment, for more information on the assets and liabilities classified as held for sale and discontinued operations. Recently Adopted Accounting Pronouncements - Effective October 1, 2019, the Company adopted ASU 2016-02 and related standards (collectively ASC 842, Leases). This new guidance aligns the measurement of leases under GAAP more closely with International Financial Reporting Standards by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The Company elected the optional transition method and adopted the new guidance on a modified retrospective basis with no restatement of prior period amounts. Further, the Company elected to apply the package of practical expedients which allows companies to carry forward original lease determinations, lease classifications, and accounting for initial direct costs. Energizer also made the policy elections upon adoption for the exclusion of short term leases on the balance sheet and to not separate lease and non-lease components. The adoption of ASC 842, Leases, resulted in the recognition of additional assets and corresponding liabilities on the Consolidated (Condensed) Balance Sheet for the Company's operating leases; however, it did not have a material impact on the Consolidated (Condensed) Statement of Earnings and Comprehensive Income, the Consolidated (Condensed) Statement of Cash Flows and the Consolidated (Condensed) Statement of Shareholders' Equity/(Deficit), including retained earnings. Refer to Note 10, Leases, for further information. Recently Announced Accounting Pronouncements - In March 2020, the FASB issued ASU 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendment provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on contracts, hedging relationships and other transactions that reference LIBOR. These updates are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is currently evaluating our contracts and the optional expedients provided by this update.
