Revenue, description of timing	For contract manufacturing arrangements, revenue is primarily recognized throughout the production cycle, which typically lasts up to 90 days, resulting in the recognition of contract assets until the related services are completed and the customers are billed. Additionally, for arrangements containing a performance obligation to deliver software that can be used with medical devices, we recognize revenue upon delivery of the software, which results in the recognition of contract assets when customers are billed over time, generally over one to five years. For bundled contracts involving equipment delivered up-front and consumable medical products to be delivered over time, total contract revenue is allocated between the equipment and consumable medical products. In certain of those arrangements, a contract asset is created for the difference between the amount of equipment revenue recognized upon delivery and the amount of consideration initially receivable from the customer. In those arrangements, the contract asset becomes a trade account receivable as consumable medical products are provided and billed, generally over one to seven years.
