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, 2023 (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, 2023 are not necessarily indicative of the results that may be expected for the full year ending February 29, 2024. The consolidated balance sheet at February 28, 2023 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.
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 other than those noted below. Critical Accounting Estimates during the Six Months Ended August 31, 2023 (Note 10) To the extent the transaction price in a contract with a customer includes variable consideration, the Company estimates the amount of variable consideration that should be included in the price utilizing either the expected value method or the most likely amount method, depending on the nature of the variable consideration. The Company also estimates whether and how much variable consideration is subject to constraint if it cannot conclude it is probable that a significant reversal in revenue will not occur, due to factors such as: the consideration being highly susceptible to factors outside the Company’s influence, the period of time before the variable consideration is resolved, the Company’s previous experience with similar contracts, the Company’s history of price concessions or changing of payment terms, and whether there is a large number and broad range of possible variable consideration amounts. To the extent the Company determines that there is a significant financing component in a contract with a customer, it determines the impact of the time value of money in adjusting the transaction price to account for the income associated with the financing component by estimating the discount rate that would be reflected in a separate financing transaction between the customer and the Company at contract inception, based upon the credit characteristics of the customer receiving financing in the contract.
