Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies - We prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for complete financial statements and these unaudited financial statements should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended November 30, 2020, as amended by Form 10-K/A filed on March 30, 2021 (together, the "2020 10-K"). We made no material changes in the application of our significant accounting policies that were disclosed in our 2020 10-K. We have prepared the accompanying unaudited condensed consolidated financial statements on the same basis as the audited financial statements included in our 2020 10-K, and these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of the interim periods presented. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full fiscal year.
Use of Estimates	Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an on-going basis, management evaluates its estimates and records changes in estimates in the period in which they become known. These estimates are based on historical data and experience, as well as various other assumptions that management believes to be reasonable under the circumstances. The most significant estimates relate to: the timing and amount of revenue recognition, including the determination of the nature and timing of the satisfaction of performance obligations, the standalone selling price of performance obligations, and the transaction price allocated to performance obligations; the realization of tax assets and estimates of tax liabilities; fair values of investments in marketable securities; intangible assets and goodwill valuations; the recognition and disclosure of contingent liabilities; the collectability of accounts receivable; and assumptions used to determine the fair value of stock-based compensation. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements Financial Instruments - Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"), which requires measurement and recognition of expected credit losses for financial assets measured at amortized cost, including accounts receivable, upon initial recognition of that financial asset using a forward-looking expected loss model, rather than an incurred loss model. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses when the fair value is below the amortized cost of the asset, removing the concept of "other-than-temporary" impairments. The Company adopted this standard effective December 1, 2020. The adoption of this standard did not have a material effect on the Company’s condensed consolidated financial statements. Recently Issued Accounting Pronouncements Convertible Debt In August 2020, the FASB issued Accounting Standards Update No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06"), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. The standard eliminates the liability and equity separation model for convertible instruments with a cash conversion feature. As a result, after adoption, entities will no longer separately present an embedded conversion feature for such debt in equity. Additionally, the debt discount resulting from the separation of the embedded conversion feature will no longer be amortized into income as interest expense over the instrument’s life. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. The standard also requires applying the if-converted method to calculate the impact of the convertible instrument on diluted earnings per share. The standard is effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020. It can be adopted on either a full retrospective or modified retrospective basis. The Company plans to adopt this standard in accordance with the full retrospective approach in the first quarter of fiscal year 2022. We have substantially completed our assessment of the retrospective application of this new standard to our historical financial statements. On a preliminary basis, we believe that the retrospective impact of the adoption of the standard on fiscal year 2021 results will be a decrease of interest expense of approximately $6.9 million, an increase of notes payable of approximately $56.0 million, a decrease of deferred tax liabilities of approximately $13.7 million, a decrease of additional paid-in capital of approximately $49.2 million, and an increase of retained earnings of approximately $6.9 million. We will finalize our retrospective presentation of our historical financial statements under the new standard in connection with our 10-Q filings during fiscal year 2022 and our 10-K for the fiscal year ending November 30, 2022.
