Accounts Receivable [Abstract]

Accounts Receivable

4. Accounts Receivable

We grant credit to our customers in the normal course of business and, generally, do not require collateral or any other security to support amounts due.  If necessary, we have an outside party assist us with performing credit and reference checks and establishing credit limits for the customer.  Accounts outstanding longer than the contractual payment terms are considered past due.  We carry our accounts receivable at the original invoice amount less an estimate made for doubtful receivables based on a periodic review of all outstanding amounts.  We determine the allowance for doubtful accounts by considering a number of factors, including the length of time accounts receivables are past due, customer financial condition and ability to pay the obligation, historical and expected credit loss experience, and the condition of the general economy and the industry as a whole.  We write off accounts receivable when deemed uncollectible.  We record recoveries of accounts receivable previously written off when received.  We are not always able to timely anticipate changes in the financial condition of our customers and if circumstances related to these customers deteriorate, our estimates of the recoverability of accounts receivable could be materially affected and we may be required to record additional allowances.  Alternatively, if more allowances are provided than are ultimately required, we may reverse a portion of such provisions in future periods based on the actual collection experience.  Historically, the accounts receivable balances we have written off have generally been within our expectations.  The allowance for doubtful accounts was $31,000 and $11,000 at September 30, 2011 and March 31, 2011, respectively.
