The Company maintains an allowance for bad debt based upon management's evaluation and judgment of potential net loss. The allowance is estimated based upon historical experience, the effects of current developments and economic conditions and of each customer’s current and anticipated financial condition. Estimates and assumptions are periodically reviewed and updated. Any resulting adjustments to the allowance are reflected in current operating results.
