Acquisitions and Divestitures
Acquisitions and Divestitures	NOTE 2. Acquisitions and Divestitures 3M makes acquisitions of certain businesses from time to time that the Company feels align with its strategic intent with respect to, among other factors, growth markets and adjacent product lines or technologies. Goodwill resulting from business combinations is largely attributable to the existing workforce of the acquired businesses and synergies expected to arise after 3M's acquisition of these businesses. In addition to business combinations, 3M periodically acquires certain tangible and/or intangible assets and purchases interests in certain enterprises that do not otherwise qualify for accounting as business combinations. These transactions are largely reflected as additional asset purchase and investment activity. During the six months ended June 30, 2015, the purchase price paid for business combinations (net of cash acquired) was $153 million, which primarily related to 3M's acquisition of Ivera Medical Corp. (discussed below). In March 2015, 3M (Health Care Business) purchased all of the outstanding shares of Ivera Medical Corp., headquartered in San Diego, California. Ivera Medical Corp., with annual sales of approximately $30 million, is a manufacturer of health care products that disinfect and protect devices used for access into a patient's bloodstream. The allocation of purchase price related to this acquisition is considered preliminary, largely with respect to intangible assets, and tax-related assets and liabilities. In addition, in the first quarter of 2015, 3M (Industrial Business) purchased the remaining interest in a former equity method investment for an immaterial amount. Purchased identifiable finite-lived intangible assets related to the Ivera Medical Corp. acquisition which closed in the six months ended June 30, 2015 totaled $51 million. The associated finite-lived intangible assets acquired will be amortized on a systematic and rational basis (generally straight line) over a weighted-average life of 13 years (lives ranging from two to 16 years). Acquired in-process research and development and identifiable intangible assets for which significant assumed renewals or extensions of underlying arrangements impacted the determination of their useful lives were not material. Pro forma information related to acquisitions was not included because the impact on the Company's consolidated results of operations was not considered to be material. In June 2015, 3M (Safety and Graphics Business) announced that it had entered into a definitive agreement to acquire Capital Safety, headquartered in Bloomington, Minnesota, from KKR & Co. L.P. for a total enterprise value of $2.5 billion including the assumption of approximately $0.7 billion of debt, net of cash acquired. Capital Safety is a leading global provider of fall protection equipment, one of the fastest-growing safety categories within the global personal protective equipment industry. Capital Safety's sales, adjusted to include recent acquisitions on a full-year basis, were approximately $430 million for its fiscal year ended March 31, 2015. The transaction is expected to close in the third quarter of 2015, subject to customary closing conditions and regulatory approvals. In February 2015, 3M (Industrial Business) announced that it had entered into a definitive agreement with Polypore International Inc., headquartered in Charlotte, North Carolina, to acquire the assets and liabilities associated with Polypore's Separations Media business for a total purchase price of approximately $1.0 billion. Polypore's Separations Media business is a leading provider of microporous membranes and modules for filtration in the life sciences, industrial and specialty segments with annual sales of approximately $208 million for the 2014 fiscal year ended January 3, 2015. Separately, Asahi Kasei, a leading diversified chemical manufacturer based in Tokyo, Japan, announced that it entered into a definitive merger agreement to acquire Polypore's Energy Storage business. Both transactions are subject to regulatory approvals and customary closing conditions. In addition, both transactions are conditioned on 3M's transaction with Polypore closing immediately prior to the closing of Asahi Kasei's transaction with Polypore. These transactions are expected to be completed in the third quarter of 2015. In January 2015, 3M (Electronics and Energy Business) completed the sale of its global static control business to Desco Industries Inc., based in Chino, California. 2014 sales of this business were $46 million. This transaction was not considered material. Refer to Note 2 in 3M's 2014 Annual Report on Form 10-K for more information on 3M's acquisitions and divestitures.
