FINANCIAL INSTRUMENTS

The fair values of cash, accounts receivable, other receivables and accounts payable approximated their carrying values because of the short-term nature of these instruments.  Accounts receivable consists primarily of amounts due from our customers, net of allowances.  Other receivables consist primarily of amounts due from employees (sales persons’ advances in excess of commissions earned and employee travel advances); other customer receivables, net of allowances; and expected insurance recoveries.  The carrying amounts of our revolving line of credit, our mortgages and other short-term financing obligations also approximate fair value, as they are comparable to the available financing in the marketplace during the year.
