Basis Of Presentation And Summary Of Significant Accounting Policies [Abstract]
Basis Of Presentation And Summary Of Significant Accounting Policies	Note 2. Basis of Presentation and Summary of Significant Accounting Policies Basis of Consolidation The condensed consolidated financial statements included herein have been prepared by the Company, without audit, according to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The August 31, 2019 year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. In the opinion of management, the unaudited financial information for the interim periods shown reflects all adjustments necessary for a fair statement thereof and such adjustments are of a normal recurring nature. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended August 31, 2019, which was filed with the SEC on October 22, 2019. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year. Foreign Currency Forward Contracts In the normal course of business, the Company employs established policies and procedures to manage its exposure to fluctuations in foreign currency exchange rates. The Company’s U.K. subsidiary, whose functional currency is Pound Sterling, utilizes foreign currency forward contracts to limit its exposure to net asset balances held in non-functional currencies, specifically the Euro. The Company regularly monitors its foreign currency exchange rate exposures to ensure the overall effectiveness of its foreign currency hedge positions. While the Company engages in foreign currency hedging activity to reduce its risk, for accounting purposes, none of its foreign currency forward contracts are designated as hedges. Foreign currency forward contracts are carried at fair value, with net realized and unrealized gains and losses recognized currently in other income (expense) in the Company’s consolidated statements of operations. Cash flows from settlements of foreign currency forward contracts are included in operating activities in the consolidated statements of cash flows. Foreign currency forward contracts in an asset position at the end of the reporting period are included in other current assets, while foreign currency forward contracts in a liability position at the end of the reporting period are included in accrued liabilities in the Company’s consolidated balance sheets. At November 30, 2019, the Company had a notional amount of $9.6 million outstanding in foreign currency forward contracts, which will mature on February 28, 2020. Unrealized net gains and losses related to foreign currency forward contracts were not significant at November 30, 2019 and November 30, 2018. Realized net gains and losses related to foreign currency forward contracts were not significant for both the three months ended November 30, 2019 and November 30, 2018. Both unrealized and realized net gains and losses are recorded in other income on the Company’s consolidated statements of operations. Fair Value of Financial Instruments Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures”, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes its financial assets and liabilities measured at fair value into a hierarchy that categorizes fair value measurements into the following three levels based on the types of inputs used in measuring their fair value: Level 1: Observable inputs such as quoted market prices in active markets for identical assets or liabilities; Level 2: Observable market-based inputs or observable inputs that are corroborated by market data; and Level 3: Unobservable inputs reflecting the Company’s own assumptions. Under fair value accounting, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. As of November 30, 2019, the Company had no assets or liabilities that are measured at fair value in the financial statements on a recurring basis, with the exception of the foreign currency forward contracts, which are classified as Level 2 within the fair value hierarchy. The carrying values of cash equivalents, short-term investments and short-term borrowings are recorded at cost, which approximates their fair values, based on Level 2 inputs, primarily due to their short-term maturities. In addition, the carrying value of borrowings held under the Company’s revolving credit facility approximates fair value, based on Level 2 inputs, due to the variable nature of underlying interest rates, which generally reflect market conditions. The Company’s fixed rate long-term borrowings consist of senior notes which are also classified as Level 2 within the fair value hierarchy and are recorded at carrying value. The Company estimates that the fair value of its senior notes, based on Level 2 inputs, was approximately $19.2 million as of November 30, 2019, which was determined based on a discounted cash flow analysis using current market interest rates for instruments with similar terms, compared to its carrying value of $18.4 million. During the three months ended November 30, 2019, the Company did not record any significant nonrecurring fair value measurements for assets or liabilities in periods subsequent to their initial recognition. Recently Adopted Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, “Leases” under ASC 842, which supersedes lease accounting and disclosure requirements in ASC 840. The new standard establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for leases with fixed payment obligations and terms longer than twelve months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. The Company adopted this new guidance on September 1, 2019 following the optional transition method described in ASU No. 2018-11, “Leases – Targeted Improvements” which was issued in July 2018, rather than the original modified retrospective approach that requires entities to apply the guidance at the beginning of the earliest period presented in the financial statements. Under the optional transition method, entities shall recognize the cumulative effect of initially applying the guidance as an adjustment to the opening balance of retained earnings on September 1, 2019. Therefore, the requirements of this guidance only apply for periods presented that are after the date of adoption and does not affect comparative periods. ‎ Upon adoption, the Company elected practical expedients to: (i) not separate lease components from nonlease components for real estate – office buildings, machinery and equipment, lab equipment, office equipment, furniture and fixtures, and IT equipment; and (ii) exclude leases with an initial term of 12 months or less from the consolidated balance sheets and will recognize related lease payments in the consolidate statements of operations on a straight-line basis over the lease term. The Company did not elect the hindsight practical expedient and also did not elect the package of practical expedients that would allow the Company to retain its conclusions under prior guidance for lease classification and initial direct costs for leases that commenced before the September 1, 2019 implementation date. During the implementation of this new standard, management was focused principally on, but not limited to, developing a complete inventory of the Company’s lease contracts and the terms and conditions contained within these contracts to appropriately account for them under the new lease model. Additionally, the Company has implemented updates to its accounting policies, business processes, systems and internal controls in support of adopting this new standard. Upon adoption on September 1, 2019, the Company’s total assets increased by $9.0 million and total liabilities increased by $9.2 million in the Company’s consolidated balance sheets. The standard did not have a material impact on the consolidated statements of operations or cash flows. Upon adoption, the cumulative effect of initially applying the guidance was insignificant and therefore no adjustment to the opening balance of retained earnings was made on September 1, 2019. See Note 6 – Leases for additional information and incremental disclosures related to the adoption of this standard. Recently Issued Accounting Standards Recent accounting pronouncements pending adoption are either not applicable or are not expected to have a material impact on the Company’s consolidated balance sheets, statement of operations or cash flows.
