Feb. 11, 2011 — -- Though Egypt's Hosni Mubarak stepped down from the presidency, leaving Cairo for a resort town, experts say his personal wealth will likely remain intact in other countries.
Sources told ABC News that Mubarak left Cairo for a town called Sharm el-Sheikh, 250 miles away on the Red Sea. Mubarak, however, has vowed never to leave Egypt.
Protestors have long demanded that Mubarak be tried for his corruption, though it is too early to tell what will happen to him. Meanwhile there are reports that Mubarak is occupying an entire floor of one of the many hotels in Sharm el-Sheikh, according to Christopher Davidson, professor of Middle East Politics at Durham University in England.
Davidson said Sharm el-Sheikh, where Mubarak has at least one residence, is a small, wealthy area that attracts vacationers.
"This feels like a different country to Egypt in many ways," said Davidson. "It's relatively difficult to get there. There are police roadblocks you have to get through."
The Swiss government said Friday it is freezing any money belonging to Mubarak or his family in Switzerland.
But Davidson said the former president's wealth in real estate around the world will be more difficult to seize.
"I think it will be only a small part of the cake," said Davdison. "And I reckon it's not his entire wealth."
The Mubarak family's wealth was built largely from military contracts during his days as an air force officer, according to experts. He eventually diversified his investments through his family when he became president in 1981. The family's net worth may be as much as $40 billion, by some estimates.
Amaney Jamal, a political science professor at Princeton, said the estimates are comparable with the vast wealth of leaders in other Gulf countries.
"The business ventures from his military and government service accumulated to his personal wealth," said Jamal. "There was a lot of corruption in this regime and stifling of public resources for personal gain."
Jamal said that Mubarak's assets are most likely in banks outside of Egypt, possibly in the United Kingdom and Switzerland.
"This is the pattern of other Middle Eastern dictators so their wealth will not be taken during a transition, she said. "These leaders plan on this."
Mubarak, his wife and two sons were able to also accumulate wealth through a number of business partnerships with foreigners, said Davidson. He said Egyptian law requires that foreigners give a local business partner a 51 percent stake in most ventures.
Aladdin Elaasar, author of "The Last Pharaoh: Mubarak and the Uncertain Future of Egypt in the Obama Age," said the Mubaraks own several residences in Egypt, some inherited from previous presidents and the monarchy, and others he has built.
"He had a very lavish lifestyle with many homes around the country," said Elaasar.
Gross national income is $2,070 per family in Egypt, the World Bank estimates. About 20 percent of the population lives below the poverty line, according to a 2010 report by the CIA.
"Gamal and Alaa are partners in the biggest trade and industrial companies in Egypt, practically paying nothing," Elaasar wrote in his book of Mubarak's two sons. Elaasar said the sons have shares in Chili's restaurants, Hyundai and Skoda auto dealerships, Vodafone, and several luxury hotel and residential properties.
Mansour Amer, chairman of Amer Group Holdings and franchisee of 19 Chili's restaurants in Egypt, denied any relation to Mubarak's family.
"We have nothing to do with any political figure," said Amer. "We are very well known in our community and we have no ties to them."
Dina Ghabbour, chief strategic officer of GB Auto, owner of the Hyundai dealership in Cairo, said the Mubaraks do not own any shares in the company.
The Mubarak family owns properties in London, Paris, Madrid, Dubai, Washington, D.C., New York and Frankfurt, according to a report from IHS Global Insight.
Davidson said the family's net worth, however -- $17 billion for Mubarak, $10 billion for his second son, Gamal, and $40 billion for the family -- are really just estimates.
"Of course, by definition, bank accounts in Switzerland are a secret so we cannot get a full picture," said Davidson.
Robert Springborg, a professor at the Naval Postgraduate School and a Middle East scholar, said while the family is very wealthy, they have not been extremely overt with their wealth.
"One of the sons has a nice apartment in Cairo but nothing hugely lavish," said Springborg. "There are many other people in Egypt who live a more lavish lifestyle than them."
Whatever Mubarak's wealth is, Davidson said Mubarak will not likelly be prosecuted until his entire regime falls.
"We've only had one man removed," said Davidson. "It's really only the beginning of the story."
