In 2006, Bain Capital and Kohlberg Kravis Roberts, together with Merrill Lynch and the Frist family (which had founded the company) completed a $31.6 billion acquisition of Hospital Corporation of America, 17 years after it was taken private for the first time in a management buyout. At the time of its announcement, the HCA buyout was the first of several to set new records for the largest buyout, eclipsing the 1989 buyout of RJR Nabisco. It was later surpassed by the buyouts of EQ Office and TXU. In August 2006, Bain was part of the consortium, together with Kohlberg Kravis Roberts, Silver Lake Partners, and AlpInvest Partners, that acquired a controlling 80.1% share of semiconductors unit of Philips for €6.4 billion. The new company, based in the Netherlands, was renamed NXP Semiconductors.
