Merger attempt with London Stock Exchange
In December 2005, the London Stock Exchange Group (LSE) rejected a £1.6 billion takeover offer from Macquarie Bank. The LSE described the offer as "derisory." It then received a bid in March 2006 for £2.4 billion from NASDAQ, which was also rejected by the LSE. NASDAQ later pulled its bid, and less than two weeks later on April 11, 2006, struck a deal with LSE's largest shareholder, Ameriprise Financial's Threadneedle Asset Management unit, to acquire all of that firm's stake, consisting of 35.4 million shares, at £11.75 per share. NASDAQ also purchased 2.69 million additional shares, resulting in a total stake of 15%. While the seller of those shares was undisclosed, it occurred simultaneously with a sale by Scottish Widows of 2.69 million shares. The move was seen as an effort to force LSE to negotiate either a partnership or eventual merger, as well as to block other suitors such as NYSE Euronext, owner of the New York Stock Exchange.
Subsequent purchases increased NASDAQ's stake to 29%, holding off competing bids for several months. However only a further 0.4% of shareholders accepted the offer by the deadline and therefore the offer was rejected  on February 10, 2007.
