Organization, Consolidation and Presentation of Financial Statements [Abstract]
Collaborative Arrangement Disclosure [Text Block]	Collaborative and Other Arrangements On February 3, 2017, we entered into two MSAs, (i) whereby Pfizer will manufacture and supply us with certain agreed upon products for an initial five-year term with a one-time two-year option to extend and (ii) whereby we will manufacture and supply Pfizer certain agreed upon products for a term of five or ten years depending on the product, also with a one-time two-year option to extend. The MSAs provide each party with mutually beneficial interests and both of the MSA's are to be jointly managed by both Pfizer and ICU. The initial supply price, which will be annually updated, is in full consideration for all costs associated with the manufacture, documentation, packaging and certification of the products. On February 3, 2017, as part of the HIS business acquisition, we entered into an agreement with Pfizer, whereby Pfizer will provide certain transitional services to us for finance, business technology, regulatory, human resources, global operations, procurement, quality and global commercial operation services ("Enabling Function Services"). We pay a monthly service fee for each service provided, and share equally with Pfizer in certain set-up costs and, as applicable, service exit costs. Our share of the set-up costs and service exit costs, in the aggregate, are not to exceed $22.0 million. The service fees are subject to a fee cap of (i) $62.5 million during the initial twelve month period and (ii) $31.3 million during the subsequent six month period. Only the Enabling Function Services are subject to the fee cap, any services provided after expiration of the agreement or services that are not Enabling Function Services may result in service fees outside the fee cap. The service fees are intended to reasonably approximate Pfizer’s cost of providing the Enabling Function Services. We may terminate, in whole only, any particular service and the fee cap would be reduced proportionate to the services terminated. Partial reduction in the provision of any specific service may be made but only with the prior written consent of Pfizer. On February 3, 2017, as part of the HIS business acquisition, we also entered into a reverse transitional services agreement, where we will provide to Pfizer certain transitional services ranging in term from three to eighteen months. Services include support for real estate, research and development, infrastructure, logistics, quality, site operations, safety, commercial and finance, and regulatory support services.
