Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business - Energizer Holdings, Inc., including its subsidiaries, (Energizer or the Company) is a global manufacturer, marketer and distributer of household batteries, specialty batteries and portable lights under the Energizer® and Eveready® brand names. Energizer offers batteries using lithium, alkaline, carbon zinc, nickel metal hydride, zinc air and silver oxide constructions. On July 1, 2016, Energizer expanded its portfolio of brands with the acquisition of HandStands Holding Corporation (the auto care acquisition), a leading designer and marketer of automotive fragrance and appearance products. With the auto care acquisition, the Company's brands now include Refresh Your Car!®, California Scents®, Driven®, Bahama & Co.®, LEXOL® and Eagle One®. Basis of Presentation - The accompanying unaudited Consolidated Condensed Financial Statements include the accounts of Energizer and its subsidiaries. All significant intercompany transactions are eliminated. Energizer has no material equity method investments, variable interests or non-controlling interests. The accompanying unaudited 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 condensed Consolidated 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. Certain reclassifications have been made to the prior year financial statements to conform to the current presentation. Operating results for any quarter are not necessarily indicative of the results for any other quarter or for the full year. These statements should be read in conjunction with the financial statements and notes thereto for Energizer for the year ended September 30, 2016 included in the Annual Report on Form 10-K dated November 15, 2016. The auto care acquisition occurred during the fourth fiscal quarter of 2016 and the purchase price allocation was finalized as of September 30, 2016. The periods ended June 30, 2016 do not include any activity from the auto care acquisition. The quarter and nine months ended June 30, 2017 include revenues of $25.9 and $83.1, respectively, and earnings before income taxes of $2.9 and $12.0, respectively, related to the auto care acquisition. Recently Adopted Accounting Pronouncements - During the quarter ended December 31, 2016, the Company early adopted FASB ASU 2016-09, Compensation - Stock Compensation. ASU 2016-09 simplifies the accounting for share-based payment transactions, including the income tax consequences and classifications on the statement of cash flows. The provisions in ASU 2016-09 resulted in the following impacts upon adoption: Excess tax benefits created upon the vesting of restricted stock equivalent awards (RSEA) are now recorded as a discrete item within the income tax provision. These amounts were previously recorded as an adjustment to Additional paid in capital. During the nine months ended June 30, 2017, $1.1 was recorded as a discrete benefit in our income tax provision. This ASU provision was applied on a modified retrospective basis; however no cumulative effect adjustment was necessary to retained earnings. Excess tax benefits are now required to be classified with other income tax cash flows as a Cash Flow from Operating Activities. This was previously reported as a Cash Flow from Financing Activity. The $1.1 excess tax benefit for the nine months ended June 30, 2017 is reflected within the Changes in current assets and liabilities used in operations line. The Company has applied this provision prospectively and the comparable prior year amount of $0.8 is reflected in Cash Flow from Financing Activities. Cash paid by an employer when directly withholding shares for tax withholding purposes are now required to be classified as a Cash Flow from Financing Activities. For the nine months ended June 30, 2017 and June 30, 2016, the Company has reported $8.2 and $4.1, respectively, for Taxes paid for withheld share payments as a Cash Flow used by Financing Activity. This presentation is consistent with prior year. No other provisions of this guidance had an impact on the financial statements. During the quarter ended December 31, 2016, the Company adopted ASU 2015-05, Intangibles Goodwill and other internal-use software (Subtopic 350-40), which provides criteria to review cloud computing arrangements to determine whether the arrangement contains a software license or is solely a service contract. If the arrangement is determined to be a software license, fees paid to the vendor would be within the scope of internal-use software guidance. If not, the fees paid would be expensed as incurred. The Company's historical accounting for cloud computing arrangements was consistent with this guidance and no change in accounting was required. During the quarter ended December 31, 2016, the Company adopted FASB ASU 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, which requires management to assess the Company's ability to continue as a going concern and to provide related disclosures in certain circumstances. Management's assessment discovered no uncertainties about the Company's ability to continue as a going concern. Recently Issued Accounting Pronouncements - On May 28, 2014, the FASB issued ASU2014-09, Revenue from Contracts with Customers which provides a single comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries and across capital markets. On August 12, 2015, the FASB issued a one-year deferral of the effective date of the ASU. The update will now be effective for Energizer beginning October 1, 2018. Energizer is in the process of evaluating the impact the revised guidance will have on its financial statements. On October 24, 2016, the FASB issued ASU 2016-16, Intra-entity Transfers of Assets Other Than Inventory. This ASU requires tax expense to be recognized from the sale of intra-entity assets, other than inventory, when the transfer occurs, even though the effects of the transaction are eliminated in consolidation. Under the current guidance, the tax effects of transfers would have been deferred until the transferred asset was sold or otherwise recovered through use. Upon adoption, any deferred charge previously established upon the intra-company transfer would be recorded as a cumulative effect adjustment to retained earnings. At September 30, 2016, the Company had a deferred charge of $51.2 included in Other assets. During the quarter ended December 31, 2016, new IRS regulations were passed that resulted in the recognition of an additional deferred charge. As of June 30, 2017, the total deferred charge is $61.0. The update will be effective for Energizer beginning October 1, 2018 with early adoption permitted in the first interim period of a fiscal year. The Company expects to adopt the new guidance during the first quarter of fiscal 2018. On January 5, 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business. This ASU creates a more practical definition and guidelines to determine whether a set of assets and activities is a business. This simplifies the decision making process of determining whether a purchase constitutes a business combination or an acquisition of assets. This ASU is effective for the Company for any new acquisitions starting October 1, 2018. On January 26, 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. This ASU eliminates the need to assign the fair value of a reporting unit to each of its assets and liabilities when quantifying an impairment charge. The impairment charge would now be determined based on the comparison of the fair value of a reporting unit to its carrying amount. The Company will adjust its goodwill testing procedures accordingly upon adoption. This ASU is effective for the Company starting with its annual goodwill impairment tests for fiscal year 2021. On March 10, 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires the service component of the net periodic pension cost to be reported in the same income statement line item as similar compensation costs, while all other pension cost components should be reported separately from the service cost component on the income statement. The update will be effective for Energizer beginning October 1, 2018 with early adoption permitted in the first interim period of a fiscal year. The Company will adjust its income statement presentation as appropriate at the time of adoption.
