Note 7 - Valuation Accounts

We report accounts receivable at net realizable value. Our terms of sale provide the basis for when accounts become delinquent or past due. We provide an allowance for doubtful accounts equal to the estimated uncollectible amounts, based on historical collection experience and a review of the current status of accounts receivable.  Receivables are generally charged off and sent to a collections agency after ninety days past due, unless we believe that collection is reasonably assured. At December 31, 2011, we recorded an allowance for doubtful accounts of $19,000. At December 31, 2010, we concluded that an allowance for doubtful accounts was not required.
