The most significant estimates in our consolidated financial statements relate to accrued expenses and the fair value of stock-based compensation and warrants. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates. Changes in estimates are reflected in reported results in the period in which they become known.</p>
