Inventories [Policy Text Block]
Inventories are stated at the lower of cost or market. Amounts removed from inventory are recorded on an average cost basis.
Accounts Receivable [Policy Text Block]
Accounts receivable are reported on the consolidated balance sheet net of an allowance for doubtful accounts. The allowance is based on our evaluation of the receivable portfolio under current conditions, overall portfolio quality, review of specific problems and such other factors that, in our judgment, deserve recognition in estimating losses.
