Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill: Goodwill represents the excess of cost over the fair value of identifiable net assets of a business acquired and is assigned to one or more reporting units. The Company tests each reporting unit’s goodwill for impairment at least annually in the fourth quarter and between annual tests if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. The Company is permitted to first assess qualitative factors to determine whether the two-step goodwill impairment test is necessary. If the qualitative assessment results in a determination that the fair value of a reporting unit is more-likely-than-not less than its carrying amount, the Company performs the two-step goodwill impairment test. The Company may bypass the qualitative assessment for any reporting unit in any period and proceed directly to step one of the two-step goodwill impairment test. In the first step, the Company compares the fair value of the reporting unit to its carrying amount. If the reporting unit’s fair value exceeds its carrying amount, goodwill is not impaired. If the carrying amount of a reporting unit is positive and exceeds the reporting unit’s fair value, the Company performs the second step to measure the amount of the reporting unit’s goodwill impairment loss, if any. In the second step, the Company assigns the reporting unit’s fair value to the reporting unit’s assets and liabilities using acquisition method accounting to determine the implied fair value of the reporting unit’s goodwill. The implied fair value of the reporting unit’s goodwill is then compared with the carrying amount of the reporting unit’s goodwill to determine the goodwill impairment loss to be recognized, if any. See Note 11 for further information about the goodwill impairment tests in 2014, 2013 and 2012.

Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]

Other Intangible Assets: Other intangible assets consist of purchased technology and patents, in-process research and development (IPR&D) acquired in a business combination, customer lists and relationships, trademarks and tradenames, licenses and distribution agreements. Definite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives ranging from three to 20 years. Certain trademark assets are considered indefinite-lived intangible assets and are not amortized.

The Company's policy defines IPR&D as the value of technology acquired for which the related projects have substance and are incomplete. IPR&D acquired in a business acquisition is recognized at fair value and requires the IPR&D to be capitalized as an indefinite-lived intangible asset until completion of the IPR&D project or abandonment. Upon completion of the development project (generally when regulatory approval to market the product is obtained), an impairment assessment is performed prior to amortizing the asset over its estimated useful life. If the IPR&D projects are abandoned, the related IPR&D assets would be written off. The purchase of certain intellectual property assets related to technology or products without regulatory approval is considered a purchase of assets rather than the acquisition of a business. For such purchases, rather than being capitalized, any IPR&D acquired in such asset purchases is expensed immediately.

The Company also reviews its indefinite-lived intangible assets for impairment regularly to determine if any adverse conditions exist that would indicate impairment or when impairment indicators exist. The Company assesses its indefinite-lived intangible assets for impairment at least annually to determine if any adverse conditions exist that would indicate a potential impairment by considering qualitative factors such as macroeconomic conditions, industry and market considerations, cost factors, financial performance, entity specific events, changes in net assets and project-based performance toward regulatory approvals. If the qualitative assessment results in a determination that the fair value of an indefinite-lived intangible asset is more-likely-than-not greater than its carrying amount, no additional testing is considered necessary. However, if the Company determines the fair value of its indefinite-lived intangible assets is more-likely-than-not below the carrying value, impairment indicators exist requiring a quantitative assessment to recognize an impairment loss, if necessary. See Note 11 for further information about the indefinite-lived intangible asset impairment tests.

The Company also reviews its definite-lived intangible assets for impairment when impairment indicators exist. When impairment indicators exist, the Company determines if the carrying value of its definite-lived intangible assets exceeds the related undiscounted future cash flows. In cases where the carrying value exceeds the undiscounted future cash flows, the carrying value is written down to fair value, which the Company determines using present value cash flow calculations. See Note 11 for further information about the definite-lived intangible asset impairment tests.
