Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. Our management has included all adjustments it considers necessary for a fair presentation which are of a normal, recurring nature. All intercompany accounts and transactions have been eliminated in consolidation. The accompanying financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended September 30, 2018 and as corrected below. The balance sheet as of September 30, 2018 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. Our business is subject to seasonal variations, and operating results for the three and six months ended March 31, 2019 and 2018 (the "current quarter" and "current six-months" and "prior-year quarter" and "prior-year six-months," respectively) are not necessarily indicative of the results of operations for the full fiscal year. There have been no changes in significant accounting policies as described in our Annual Report on Form 10-K for the year ended September 30, 2018, other than those described below.
Use of Estimates and Assumptions | Use of Estimates and AssumptionsThe preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, inventories, loan loss allowances, long-lived and intangible assets, share-based compensation, income taxes, contingencies and litigation. We base our estimates on historical experience, observable trends and various other assumptions that we believe are reasonable under the circumstances. We use this information to make judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.
Recently Issued Accounting Pronouncements and Significant Accounting Policies | Recently Issued Accounting Pronouncements
• | In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU requires financial assets (or groups of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected, among other provisions. The provisions of this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A reporting entity should generally apply the amendment on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting periods in which the amendment is effective. We have not identified any impacts to our financial statements that we believe will
be material as a result of the adoption of the ASU, although we continue to evaluate the impact of adoption. We believe we are following an appropriate timeline to allow for proper recognition, presentation and disclosure upon adoption of this ASU which is effective for our fiscal 2021.
• | In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU requires companies to generally recognize on the balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The provisions of this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted based upon guidance issued within the ASU. We are in the process of evaluating the impact of adopting ASU 2016-02 on our consolidated financial position, results of operations and cash flows, and anticipate a material impact on our consolidated financial position. Additionally, we are evaluating the disclosure requirements under this ASU and are identifying and preparing to implement changes to our accounting policies, practices and controls to support adoption of the ASU and have completed upgrades to our third-party software solution to support adoption. We will complete our implementation to allow for proper recognition, presentation and disclosure upon adoption of the ASU which is effective for our fiscal 2020. We currently plan to adopt this ASU using the optional transition method provided under ASU 2018-11, Leases, (Topic 842): Targeted Improvement which was issued in July 2018, allowing for application of ASU 2016-02 at the adoption date.
Please refer to Note 1 of Notes to Consolidated Financial Statements included in "Part II, Item 8 — Financial Statements and Supplementary Data" of our Annual Report on Form 10-K for the year ended September 30, 2018 for discussion of our significant accounting policies and other accounting pronouncements issued but not yet adopted.
