The NYSE has been the subject of several lawsuits regarding fraud or breach of duty and in 2004 was sued by its former CEO for breach of contract and defamation.The earliest recorded organization of securities trading in New York among brokers directly dealing with each other can be traced to the Buttonwood Agreement. Previously securities exchange had been intermediated by the auctioneers who also conducted more mundane auctions of commodities such as wheat and tobacco.^[11] On May 17, 1792 twenty four brokers signed the Buttonwood Agreement which set a floor commission rate charged to clients and bound the signers to give preference to the other signers in securities sales. The earliest securities traded were mostly governmental securities such as War Bonds from the Revolutionary War and First Bank of the United States stock, although Bank of New York stock was a non-governmental security traded in the early days.
