6. ACQUISITIONS

We made a number of business acquisitions during the years 2011, 2010 and 2009. In November 2011 we acquired ExtraOrtho, Inc. (ExtraOrtho). The ExtraOrtho acquisition enhances our position in the estimated $820 million external fixation market. In December 2010 we acquired Beijing Montagne Medical Device Co., Ltd. (Montagne) and Sodem Diffusion S.A. (Sodem). The Montagne acquisition makes us a significant provider of orthopaedic solutions in China and provides product lines tailored exclusively to the rapidly growing Chinese market. The Sodem acquisition broadens our portfolio of surgical power tools and strengthens our position in the estimated $1 billion surgical power tool market. Additionally, we have acquired a number of foreign-based distributors during the three year period.

The results of operations of the acquired companies have been included in our consolidated results of operations subsequent to the transaction dates, and the respective assets and liabilities of the acquired companies have been recorded at their estimated fair values in our consolidated statement of financial position as of the transaction dates, with any excess purchase price being allocated to goodwill. The estimated fair values of the ExtraOrtho assets are preliminary. Pro forma financial information and other information required have not been included as the acquisitions did not have a material impact upon our financial position or results of operations.
