Receivables [Abstract]  
Trade and Other Accounts Receivable, Policy [Policy Text Block]
Receivables consist of accounts receivable and the current portion of amounts due under sales-type leases. Accounts receivable primarily represent recorded revenues that have been billed. Billings and other consideration received on contracts in excess of related revenues recognized are recorded as deferred revenue. Substantially all receivables are derived from sales and related support and maintenance and professional services of our clinical, administrative and financial information systems and solutions to health care providers.

We perform ongoing credit evaluations of our clients and generally do not require collateral from our clients. We provide an allowance for estimated uncollectible accounts based on specific identification, historical experience and our judgment.
