Randa Duncan Williams is one of the four children of Enterprise Products Partners founder Dan Duncan and his wife, Jan. After her father's death in 2010, Williams and her two sisters, Milane Duncan Frantz and Dannine Duncan Avara, and brother Scott Daniel Duncan inherited the family trusts that make the siblings the largest shareholding group of the company.

The family's interest in Enterprise Products has collected about $3.7 billion in cash distributions since October 1998, according to data compiled by Bloomberg. These dividends have been adjusted for stock purchases taxes and appreciated with an allocation of 30 percent each in cash, U.S. bonds and large cap stocks, and 10 percent commodities. Dan Duncan died in 2010, when there was no estate tax in the U.S.

Of the 688 million units under family control, 118 million units are pledged as collateral to Citibank and Barclay's by Duncan family investment vehicles and aren't included in the net worth calculation, according to a May 31, 2016 form 13D/A filed with the Securities and Exchange Commission. Williams is credited with a quarter of the Duncan family's unitholdings, or about 9 percent of the company. She and her husband own about 340,000 shares independently.

Enterprise Products spokesman Rick Rainey declined to comment on the family members's net worth calculations.

Randa Duncan Williams is the non-executive chairman of the board of publicly traded Enterprise Products Partners and chairman of Enterprise Products, the closely held company that controls about one-third percent of the partnership interest of the publicly traded entity. She splits the economic interest in that partnership stake with her three siblings.

Her father, Dan Duncan, founded Enterprise Products in 1968 -- with $10,000 and two fuel trucks -- as a natural gas liquids wholesaler. He later expanded into crude pipelines, fuel storage and natural gas processing. By the time of his death in March 2010, he had parlayed that initial investment into a company with a market capitalization of about $31 billion. In the last decade of his leadership, the company delivered an annual 20 percent return on investment. Duncan had four children with his wife, Jan, who is still alive. Randa is the oldest child, followed by two sisters, Milane Duncan Frantz and Dannine Duncan Avara, and a brother, Scott Daniel Duncan.

Williams is the only Duncan sibling to hold a management role in the family business. After graduating from Rice University in 1985, with a degree in political science and economics, she received a law degree from the University of Houston and practiced law for six years. She joined Enterprise Products in 1994, rising to the level of president and chief executive officer in 2001, and then chairman in 2010. After her father's death that year, she became the sole family trustee on a board that manages the family holdings in Enterprise Products. In February 2013, she became non-executive chairman of the publicly traded company, in addition to chairman of the closely held entity.

Williams is active on the boards of several Houston educational and medical institutions, including the Houston Zoo and the Albert and Margaret Alkek Foundation, of which her husband, Charles A. Williams, is president. The couple lives in Houston with their teenage son.
