Our customers, ranging from small businesses to large/multi-national enterprises, trust us to address their most demanding data workflow challenges. Our end-to-end tiered storage solutions enable users to maximize the value of their data by making it accessible whenever and wherever needed, retaining it indefinitely and reducing total cost and complexity. We work closely with a broad network of distributors, value-added resellers (“VARs”), direct marketing resellers (“DMRs”), original equipment manufacturers (“OEMs”) and other suppliers to meet customers’ evolving needs. Our stock is traded on the New York Stock Exchange under the symbol QTM. The accompanying Consolidated Financial Statements include the accounts of Quantum and our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. In the Consolidated Balance Sheets, prior period convertible subordinated debt, current and long-term, have been presented net of debt issuance costs to conform to current period presentation. The preparation of our Consolidated Financial Statements in conformity with generally accepted accounting principles (“GAAP”) in the U.S. requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the period. We base estimates on historical experience and on various assumptions about the future that are believed to be reasonable based on available information. Our reported financial position or results of operations may be materially different under different conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies, which are discussed below. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in the current period to reflect this current information.
