MUFG Bank, Japan's largest bank, invested $9 billion in a direct purchase of a 21% ownership stake in Morgan Stanley on September 29, 2008. The payment from MUFG was supposed to be wired electronically; however, because it needed to be made on an emergency basis on Columbus Day when banks were closed in the US, MUFG cut a US$9 billion physical check, the largest amount written via physical check at the time. The physical check was accepted by Robert A. Kindler, Global Head of Mergers and Acquisitions and Vice Chairman of Morgan Stanley, at the offices of Wachtell Lipton. Concerns over the completion of the Mitsubishi deal during the October 2008 stock market volatility caused a dramatic fall in Morgan Stanley's stock price to levels last seen in 1994. It recovered once Mitsubishi UFJ's 21% stake in Morgan Stanley was completed on October 14, 2008.
