The August 31, 2020 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, 2020, which was filed with the SEC on October 21, 2020. 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	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	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 utilizes foreign currency forward contracts to limit its exposure to net asset balances held in non-functional currencies, primarily at its U.K. subsidiary. 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 May 31, 2021, the Company had a notional amount of $15.8 million outstanding in foreign currency forward contracts, which matured on June 29, 2021. Unrealized net gains and losses related to foreign currency forward contracts were not significant at May 31, 2021 and August 31, 2020. Realized net gains and losses related to foreign currency forward contracts were not significant for both the three months ended May 31, 2021 and 2020. Realized net gains and losses related to foreign currency forward contracts were not significant for both the nine months ended May 31, 2021 and 2020. Both unrealized and realized net gains and losses are recorded in other income (expense), net on the Company’s condensed consolidated statements of operations.
Fair Value Of Financial Instruments	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 May 31, 2021, 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 and short-term borrowings are recorded at cost, which approximates their fair values, primarily due to their short-term nature. 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 and are recorded at carrying value. The Company estimates that the fair value of its senior notes, based on Level 2 inputs, was approximately $66.4 million as of May 31, 2021, which was determined based on a discounted cash flow analysis using current market interest rates for instruments with similar terms, compared to their carrying value of $69.2 million. During the nine months ended May 31, 2021, the Company did not record any significant nonrecurring fair value measurements for assets or liabilities in periods subsequent to their initial recognition.

This guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year. Early adoption is permitted.

Basis Of Presentation And Summary Of Significant Accounting Policies [Abstract]

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, 2020 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, 2020, which was filed with the SEC on October 21, 2020.

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

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.

COVID-19 Considerations

The COVID-19 pandemic has adversely impacted global economic conditions and has contributed to significant volatility in financial markets beginning in early calendar year 2020, as described in the “Impact of COVID-19 on Our Business” section included in Part I – Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations. Although the Company’s current estimates contemplate current conditions, the inputs into certain of the Company’s significant and critical accounting estimates include judgments and assumptions about the economic implications of the COVID-19 pandemic and how management expects them to change in the future, as appropriate. It is reasonably possible

that actual results experienced may differ materially from the Company’s estimates in future periods, which could materially affect our results of operations and financial condition.

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 utilizes foreign currency forward contracts to limit its exposure to net asset balances held in non-functional currencies, primarily at its U.K. subsidiary. 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 May 31, 2021, the Company had a notional amount of $15.8 million outstanding in foreign currency forward contracts, which matured on June 29, 2021. Unrealized net gains and losses related to foreign currency forward contracts were not significant at May 31, 2021 and August 31, 2020. Realized net gains and losses related to foreign currency forward contracts were not significant for both the three months ended May 31, 2021 and 2020. Realized net gains and losses related to foreign currency forward contracts were not significant for both the nine months ended May 31, 2021 and 2020. Both unrealized and realized net gains and losses are recorded in other income (expense), net on the Company’s condensed consolidated statements of operations.

Fair Value Of Financial Instruments

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 May 31, 2021, 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 and short-term borrowings are recorded at cost, which approximates their fair values, primarily due to their short-term nature. 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 and are recorded at carrying value. The Company estimates that the fair value of its senior notes, based on Level 2 inputs, was approximately $66.4 million as of May 31, 2021, which was determined based on a discounted cash flow analysis using current market interest rates for instruments with similar terms, compared to their carrying value of $69.2 million. During the nine months ended May 31, 2021, the Company did not record any significant nonrecurring fair value measurements for assets or liabilities in periods subsequent to their initial recognition.

Recently Issued Accounting Standards

In December 2019, the FASB issued ASU No. 2019-12, “Simplifying the Accounting for Income Taxes” under ASC 740, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. This guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year. Early adoption is permitted. The Company is in the process of evaluating the impacts of this guidance on its consolidated financial statements and related disclosures.
