Management makes these estimates using the best information available at the time the estimates are made; however, actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the inventory valuation allowance and the treatment of the shares issued. These estimates are often based on complex judgments and assumptions that management believes to be reasonable but are inherently uncertain and unpredictable.
