The company's current name, Honeywell International Inc., is the product of a merger of Honeywell Inc. by acquisition to AlliedSignal during 1999. The company headquarters were consolidated with AlliedSignal's headquarters in Morristown, New Jersey; however, the combined company chose the name "Honeywell" because of the considerable brand recognition.[8] Honeywell was a component of the Dow Jones Industrial Average index from 1999 to 2008. Prior to 1999, its corporate predecessors were included dating back to 1925, including early entrants in the computing and thermostat industries.[9][10] In 2020, Honeywell rejoined the Dow Jones Industrial Average index[11] and the following year moved its stock listing from the New York Stock Exchange to the Nasdaq
