	May 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation and preparation	Basis of Presentation and Preparation These interim consolidated financial statements have been prepared by management in accordance with United States generally accepted accounting principles (“U.S. GAAP”). They do not include all of the disclosures required by U.S. GAAP for annual financial statements and should be read in conjunction with the audited consolidated financial statements of BlackBerry Limited (the “Company”) for the year ended February 28, 2022 (the “Annual Financial Statements”), which have been prepared in accordance with U.S. GAAP. In the opinion of management, all normal recurring adjustments considered necessary for fair presentation have been included in these interim consolidated financial statements. Operating results for the three months ended May 31, 2022 are not necessarily indicative of the results that may be expected for the full year ending February 28, 2023. The consolidated balance sheet at February 28, 2022 was derived from the audited Annual Financial Statements but does not contain all of the footnote disclosures from the Annual Financial Statements. The preparation of the consolidated financial statements requires management to make estimates and assumptions with respect to the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities. Actual results could differ from these estimates and any such differences may be material to the Company’s consolidated financial statements. Certain of the comparative figures have been reclassified to conform to the current period’s presentation. The Company is organized and managed as three reportable operating segments: Cybersecurity, IoT (collectively, “Software & Services”), and Licensing and Other, as further discussed in Note 10.
New Accounting Pronouncements	Accounting Standards Adopted During Fiscal 2023 ASU 2020-06, Debt with Conversion and Other Options In August 2020, the Financial Standards Accounting Board (“FASB”) issued a new accounting standard on the topic of debt with conversion and other options, accounting standards update (“ASU”) 2020-06. The amendment in this update simplifies the accounting for convertible instruments by reducing the number of accounting models available for convertible debt instruments and convertible preferred stock. This update also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions and requires the application of the if-converted method for calculating diluted earnings per share. The update also requires entities to provide expanded disclosures about the terms and features of convertible instruments, how the instruments have been reported in the entity’s financial statements, and information about events, conditions, and circumstances that can affect how to assess the amount or timing of an entity’s future cash flows related to those instruments. The guidance is effective for interim and annual periods beginning after December 15, 2021. The Company adopted this guidance in the first quarter of fiscal 2023 and it did not have a material impact on its results of operations, financial position and disclosures as the fair value option accounting model used by the Company is not impacted by this ASU and the Company already utilizes the if-converted method in its calculation of diluted earnings per share relating to the 1.75% Debentures (as defined in Note 5). ASU 2021-08, Business Combinations In October 2021, the FASB issued a new accounting standard on the topic of business combinations, accounting for contract assets and contract liabilities from contracts with customers, ASU 2021-08. The amendment in this update improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency. This update requires entities to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers. The guidance is effective for interim and annual periods beginning after December 15, 2022 and requires entities to prospectively apply business combinations occurring on or after the effective date of the amendments. The Company early adopted this guidance in the first quarter of fiscal 2023, and will apply it prospectively to any business acquisitions subsequent to the date of adoption. ASU 2021-10, Government Assistance In November 2021, the FASB issued a new accounting standard on the topic of government assistance, ASU 2021-10. The standard requires additional disclosures for transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including: (i) information about the nature of the transactions and related accounting policy used to account for the transactions; (ii) the line items on the balance sheet and income statement affected by these transactions including amounts applicable to each line; and (iii) significant terms and conditions of the transactions, including commitments and contingencies. The update also requires entities that omit any of the information because it is legally prohibited from being disclosed to include a statement to that effect. The guidance is effective for annual periods beginning after December 15, 2021. The Company adopted this guidance in the first quarter of fiscal 2023 and does not expect the adoption to have a material impact on its annual disclosures.
