offices and making various acquisitions. The company moved its headquarters from New York City to Greenwich, Connecticut in 1974, and then to Stamford, Connecticut in 1984. In 1980, General Re Corporation, the parent holding company, was formed and listed on the New York Stock Exchange as GRN. In 1994, General Reinsurance Corporation formed an alliance with what was then Cologne Re (Kölnische Rückversicherungs-Gesellschaft, which was founded in 1846), now General Reinsurance AG. In 1998, General Re Corporation was acquired by Berkshire Hathaway Inc., and in 2003 General Reinsurance Corporation and Cologne Re began marketing under the brand name of Gen Re. In 2009, General Reinsurance Corporation completed its purchase of Cologne Re, whose name was changed to General Reinsurance AG in 2010. AIG Securities Fraud In October 2000, some Wall Street analysts questioned the decline in American International Group (AIG) loss reserves. In an effort to quell these concerns, AIG entered into two sham reinsurance transactions with Cologne Re Dublin, a subsidiary of General Reinsurance, that had no economic substance but were designed to add $500 million in phony loss reserves to AIG’s balance sheet in the fourth quarter of 2000 and first quarter of 2001. In 2005, New York Attorney General Eliot Spitzer began an investigation into the two reinsurance transactions. Soon afterwards, AIG came under market pressure, and admitted it had undertaken what could be construed as securities fraud. The staff admitted that the two reinsurance transactions had inflated AIG’s balance sheet and propped up AIG’s stock price. In the resultant stock crash, investors lost $500 million in investments. Cologne Re Dublin's CEO, John Houldsworth, agreed to turn state's witness for the Department of Justice (DOJ) and Securities and Exchange Commission, in agreement for a plea bargain. Houldsworth then pleaded guilty to conspiring to commit securities fraud, resultantly facing a sentence of up to five years in prison and $250,000 in fines. The final sentencing was placed on hold, subject to consequential SEC prosecutions. The DOJ subsequently undertook successful prosecutions against four former Gen Re executives and one former AIG executive: CEO Ronald Ferguson was sentenced to two years in prison and fined $200,000; CFO Elizabeth Monrad was sentenced to 18 months in prison and fined $250,000; Senior Vice President Christopher Garand was sentenced to a year and a day in prison and fined $150,000; Senior Vice President and Assistant General Counsel Robert Graham was sentenced to a
