History
20th century
Simon Property Group dates to 1960, when brothers Melvin Simon and Herbert Simon began developing strip malls in Indianapolis, Indiana. In December 1993, they took their interests public as Simon Property Group in the largest initial public offering of a real estate investment trust to date. Simon Property Group merged with the newly public DeBartolo Realty Corporation, owner of the real estate assets of Edward J. DeBartolo Sr., in 1996 to form Simon DeBartolo Group. In the following year, the company acquired The Retail Property Trust for $1.2 billion in a hostile takeover. Also in 1997, in partnership with Macerich, the company acquired 12 malls from IBM's pension plan for $974.5 million. One year after these acquisitions, the company acquired Corporate Property Investors and was reverted to the Simon Property Group name.

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
