Acquisitions and Divestitures	NOTE 2. Acquisitions and Divestitures Acquisitions: 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. There were no business combinations that closed during the nine months ended September 30, 2013. Adjustments in the first nine months of 2013 to the preliminary purchase price allocations of other acquisitions within the allocation period were not material and primarily related to the 2012 acquisition of Ceradyne, Inc. The allocation of purchase price related to the acquisition of Ceradyne, Inc. in November 2012 is considered preliminary, largely with respect to certain acquired property, plant and equipment, tax-related items and certain other liabilities. Refer to Note 2 in 3M's Current Report on Form 8-K dated May 16, 2013 (which updated 3M's 2012 Annual Report on Form 10-K) for more information on 3M's 2012 acquisitions. Divestitures: In June 2013, 3M (Consumer Business) completed the sale of its Scientific Anglers and Ross Reels businesses to The Orvis Company, Inc. based in Manchester, Vermont.
