ACQUISITIONS The acquisition method of accounting is based on ASC Subtopic 805-10, “Business Combinations,” and uses the fair value concepts defined in ASC Subtopic 820-10, “Fair Value Measurements and Disclosures,” which the Company has adopted as required. The total purchase price is allocated to the net tangible and intangible assets based upon their fair values as of the acquisition dates. The excess of the purchase price over the fair values of the net tangible assets and intangible assets was recorded as goodwill. The allocation of the purchase price was based upon a valuation and is subject to change within the one-year measurement period following the acquisition. MSCI expects to continue to obtain information to assist it in determining the fair value of the net assets acquired at the acquisition date during the measurement period. *Acquisition of GMI Ratings* On August 11, 2014, the Company completed the acquisition of GMI Ratings for $15.5 million in cash through its subsidiary MSCI ESG Research Inc.
