ALLOWANCE FOR CREDIT LOSSES

Trade Receivables The Company evaluates the collectability of trade receivables based on (1) a percentage of sales related to historical loss experience and current trends and (2) periodic adjustments for known events such as specific customer circumstances and changes in the aging of accounts receivable balances. After all efforts at collection have been unsuccessful, the account is deemed uncollectible and is written off.

Financing Receivables The Company evaluates the collectability of notes and finance lease receivables (collectively, financing receivables) on a customer-by-customer basis and evaluates specific customer circumstances, aging of invoices, credit risk changes and payment patterns and historical loss experience. When the collectability is determined to be at risk based on the above criteria, the Company records the allowance for credit losses, which represents the Company’s current exposure less estimated reimbursement from insurance claims. After all efforts at collection have been unsuccessful, the account is deemed uncollectible and is written off. The following table summarizes the Company’s allowance for credit losses and recorded investment in financing receivables for the six months ended June 30, 2012:

The Company records interest income and any fees or costs related to financing receivables using the effective interest method over the term of the lease or loan. The Company reviews the aging of its financing receivables to determine past due and delinquent accounts. Credit quality is reviewed at inception and is re-evaluated as needed based on customer-specific circumstances. Receivable balances 60 days to 89 days past due are reviewed and may be placed on nonaccrual status based on customer-specific circumstances. Receivable balances are placed on nonaccrual status upon reaching greater than 89 days past due. Upon receipt of payment on nonaccrual financing receivables, interest income is recognized and accrual of interest is resumed once the account has been made current or the specific circumstances have been resolved.

As of June 30, 2012 and December 31, 2011, the recorded investment in past-due finance lease receivables on nonaccrual status was $4,928 and $1,740, respectively. The recorded investment in finance lease receivables past due 90 days or more and still accruing interest was $98 and $114 as of June 30, 2012 and December 31, 2011, respectively. The recorded investment in impaired notes receivable as of June 30, 2012 and December 31, 2011 was $2,047 and $2,047, respectively, and was fully reserved.
