run for the U.S. Senate seat from Massachusetts; he returned the day after the election in November 1994. During that time, Ampad workers went on strike, and asked Romney to intervene; Bain Capital lawyers asked him not to get involved, although he did meet with the workers to tell them he had no position of active authority in the matter. In 1994, Bain invested in Steel Dynamics, based in Fort Wayne, Indiana, a prosperous steel company that has grown to the fifth largest in the US, employs about 6,100 people, and produces carbon steel products with 2010 revenues of $6.3 billion on steel shipments of 5.3 million tons. In 1993, Bain acquired the Armco Worldwide Grinding System steel plant in Kansas City, Missouri and merged it with its steel plant in Georgetown, South Carolina to form GST Steel. The Kansas City plant had a strike in 1997 and Bain closed the plant in 2001 laying off 750 workers when it went into bankruptcy. The South Carolina plant closed in 2003 but subsequently reopened under a different owner. At the time of its bankruptcy it reported $553.9 million in debts against $395.2 in assets. Bain reported $58.4 million in profits, the employee pension fund had a liability of $44 million. Bain's investment in Dade Behring represented a significant investment in the medical diagnostics industry. In 1994, Bain, together with Goldman Sachs Capital Partners completed a carveout acquisition of Dade International, the medical diagnostics division of Baxter International in a $440 million acquisition. Dade's private equity owners merged the company with DuPont's in vitro diagnostics business in May 1996 and subsequently with the Behring Diagnostics division of Hoechst AG in 1997. Aventis, the successor of Hoechst, acquired 52% of the combined company. In 1999, the company reported $1.3 billion of revenue and completed a $1.25 billion leveraged recapitalization that resulted in a payout to shareholders. The dividend, taken together with other previous shareholder dividends resulted in an eightfold return on investment to Bain Capital and Goldman Sachs. Revenues declined from 1999 through 2002 and despite attempts to cut costs through layoffs the company entered into bankruptcy in 2002. Following its restructuring, Dade Behring emerged from Bankruptcy in 2003 and continued to operate independently until 2007 when the business was acquired by Siemens Medical Solutions. Bain and Goldman lost their remaining stock in the company as part of the bankruptcy. By the end
