The aggregate consideration paid for the Danfoss Business was EUR 120.0 million, which includes approximately EUR 1.7 million of assumed debt.  The aggregate purchase price, which is subject to working capital and related adjustments, is equal to approximately $175.7 million based on the exchange rate of Euro to U.S. dollars as of April 26, 2011.  The Company funded the transaction with cash on hand and Euro-based borrowings under its a Credit Agreement dated June 18, 2010 (the “Credit Agreement”) among the Company, certain subsidiaries of the Company as borrowers, Bank of America, N.A., as Administrative Agent, Swing Line Lender and Letter of Credit Issuer, and the other lenders referred to therein.

Its major product lines include backflow preventers, check valves and pressure reducing valves. Danfoss Socla is based in France, and its products are distributed worldwide for municipal, industrial, commercial and residential use.
