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 29, 2024 (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 and six months ended August 31, 2024 are not necessarily indicative of the results that may be expected for the full year ending February 28, 2025. The consolidated balance sheet at February 29, 2024 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 year’s presentation. The Company is organized and managed as three reportable operating segments: Cybersecurity, IoT (collectively, “Software & Services”), and Licensing, as further discussed in Note 10.
Use of estimates	Significant Accounting Policies and Critical Accounting Estimates There have been no material changes to the Company’s accounting policies or critical accounting estimates from those described in the Annual Financial Statements.
New Accounting Pronouncements	Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” on the topic of income taxes. The standard requires additional disclosure for income taxes. These requirements include: (i) requiring a public entity to disclose specific categories in the rate reconciliation; (ii) disclosure of additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate); (iii) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; (iv) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received); (v) annual disclosure of income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign; and (vi) annual disclosure of income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. For public entities, the guidance is effective for annual periods beginning after December 15, 2024. The Company will adopt this guidance in fiscal 2026 and is in the process of evaluating the new requirements. As a result, the Company has not yet determined the impact this new ASU will have on its disclosures.
