Customer Financing [Abstract]

Impaired Financing Receivable, Policy [Policy Text Block]

We determine a receivable is impaired when, based on current information and events, it is probable that we will be unable to collect amounts due according to the original contractual terms.

Financing Receivable, Allowance for Credit Losses, Policy for Uncollectible Amounts [Policy Text Block]

The adequacy of the allowance for losses is assessed quarterly. Three primary factors influencing the level of our allowance for losses on customer financing receivables are customer credit ratings, default rates and collateral values. We assign internal credit ratings for all customers and determine the creditworthiness of each customer based upon publicly available information and information obtained directly from our customers. Our rating categories are comparable to those used by the major credit rating agencies.
