2. Acquisitions In April 2011, we acquired certain assets and assumed certain liabilities of Hiprom (Pty) Ltd and its affiliates (Hiprom), a process control and automation systems integrator for the mining and mineral processing industry in South Africa. In May 2011, we purchased a majority stake in the equity of Lektronix Limited and its affiliate (Lektronix), an independent industrial automation repairs and service provider in Europe and Asia. The terms of this acquisition included mirroring put and call options for a fixed price in December 2011 with respect to the remaining minority shares. Accordingly, we recorded the Lektronix share purchase as an acquisition of all outstanding equity interests with a corresponding liability of $10.9 million related to the put/call option as of the acquisition date. The aggregate purchase price of the Hiprom and Lektronix acquisitions was $58.8 million. We recorded goodwill of $34.8 million attributable to intangible assets that do not meet the criteria for separate recognition, including an assembled workforce with industry-wide technical expertise and customer service capabilities. We assigned the full amount of goodwill for Hiprom and Lektronix to our Control Products &amp; Solutions segment. None of the goodwill recorded is expected to be deductible for tax purposes. In 2009, our Control Products &amp; Solutions segment acquired the assets and assumed certain liabilities of Xi an Hengsheng Science &amp; Technology Company Limited (Hengsheng). Hengsheng delivers automation solutions to the electrical power and other heavy process industries in central and western China. Our Control Products &amp; Solutions segment also acquired a majority of the assets and assumed certain liabilities of the automation business of Rutter Hinz Inc. (Hinz). Hinz offers industrial control systems engineering and related support, with domain expertise in industrial automation, process control and power distribution for the oil and gas industry, and other resource-based industries.
