Use of Estimates	3. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the use of estimates and assumptions by management that affect reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to stock-based compensation arrangements, the use of estimates to determine the elements of our revenue and deferred revenue, accrued expenses, and the warrant liability. Actual results could differ from these estimates. Estimates of future operating results are based upon numerous factors including past experience, known information and subjective estimates and assumptions. Actual future operating results could be materially different from management’s estimates and unforeseen events could adversely affect management’s estimates.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the use of estimates and assumptions by management that affect reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to stock-based compensation arrangements, the use of estimates to determine the elements of our revenue and deferred revenue, accrued expenses, and the warrant liability. Actual results could differ from these estimates. Estimates of future operating results are based upon numerous factors including past experience, known information and subjective estimates and assumptions. Actual future operating results could be materially different from management’s estimates and unforeseen events could adversely affect management’s estimates.
