Grace & Co. (Amicon) for approximately $129,265 in cash, including transaction costs. This acquisition was accounted for as a purchase, and accordingly, the purchase price was preliminarily allocated to the identifiable tangible and intangible assets based on the estimated fair market values of those assets. The Company also accrued $27,000 for additional costs associated with the acquisition. The purchase price was allocated to the net assets acquired as follows: Current assets $ 30,328 Property, plant and equipment 15,474 Intangible assets 50,753 Purchased Research & 68,311 Development Other assets 596 Current liabilities (9,197) $ 156,265 Identifiable intangible assets included trade names and patented and unpatented complete technology. These intangible assets will be amortized over their estimated useful lives ranging from five to thirty years. The value assigned to purchased research and development, for which technical feasibility had not been achieved, was charged to earnings in the fourth quarter of 1996 and is included in the historical Millipore statement of income for the year ended December 31, 1996. Millipore financed the acquisition of Amicon by drawing down funds on a 90 day $250,000 bridge loan which was made available to the Company as temporary financing pending finalization in January, 1997 of a long-term $450,000 revolving credit facility. Borrowings required to complete the acquisition of $124,397 are included in Millipore's historical balance sheet at December 31, 1996. As this acquisition was completed on the last business day of 1996, the assets acquired and liabilities assumed are included in Millipore's historical balance sheet at December 31, 1996. Amicon had a December 31 year end, which is the same year end as Millipore. The unaudited pro forma statement of income for the year ended December 31, 1996 was prepared as if the acquisition had occurred on January 1, 1996. Acquisition of Tylan General, Inc. On January 22, 1997, Millipore successfully completed a cash tender offer for all of the outstanding common stock of Tylan General, Inc. (Tylan) for $16.00 per share. Tylan became a wholly owned subsidiary of Millipore on January 27, 1997. The purchase price was $133,000 and was funded through the Company's $450,000 revolving credit facility discussed above. In addition, Millipore assumed all of Tylan's outstanding debt, net of cash. This acquisition will be accounted for as a purchase by Millipore in the first quarter of 1997. As part of the purchase accounting to be recorded in the first quarter of 1997, Millipore expects to record a non-tax deductible charge in the range of $50,000 to $100,000 for purchased research and development for which technical feasibility has not yet been achieved. Millipore also expects to record an accrual in the range of $35,000 in the first quarter of 1997 for transaction and other costs directly associated with the acquisition. No purchased research and development expense relating to the Tylan acquisition has been included in the pro forma statement of income for the year ended December 31, 1996. Millipore has reflected the high end of its estimate for purchased research and development expense, $100,000, as well as its estimate for costs associated with this acquisition of $35,000 as pro forma adjustments to retained earnings and accrued expenses, respectively, in the pro forma balance sheet at December 31, 1996. In addition, Millipore has assumed intangible assets acquired are $18,646 and has reflected this amount as a pro forma adjustment in the pro forma balance sheet at December 31, 1996. The unaudited pro forma balance sheet at December 31, 1996 was prepared as if the acquisition of Tylan had occurred on December 31, 1996. The unaudited pro forma statement of income for the year ended December 31, 1996 was prepared as if the acquisition of Tylan had occurred on January 1, 1996. Tylan had an October 31 year end. For purposes of presenting an unaudited pro forma statement of income for the year ended December 31, 1996, the historical results of Tylan's operations for the year ended October 31, 1996 have been included with Millipore's results of operations for the year ended December 31, 1996. For purposes of presenting the pro forma balance sheet at December 31, 1996, the historical accounts of Tylan at October 31, 1996 have been included with Millipore's balance sheet accounts at December 31, 1996. The impact resulting from these differences in periods is not material. The unaudited pro forma financial statements are intended for informational purposes and are not necessarily indicative of the future financial position or future results of operations of the combined entity. These condensed pro forma financial statements should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 1996, and the historical financial statements of Amicon and Tylan filed as part of this report on Form 8-K.
