Presidential candidate Donald Trump to reveal fortune

As other presidential candidates fight to raise money, Donald Trump is reminding everyone he's already got a lot of it.

The celebrity businessman's campaign is expected to reveal details Wednesday of his fortune, which he estimated last month at nearly $9 billion US ($11.6 billion Canadian)when announcing his Republican presidential candidacy.

If accurate, that number would make Trump the wealthiest person to ever run for president, far surpassing previous magnates like Ross Perot, business heirs like Steve Forbes or private-equity investors like Mitt Romney, the 2012 GOP nominee.

"I have a Gucci store worth more than Romney," Trump told the Des Moines Register last month, referring to the fashion company's flagship store in New York's Trump Tower.

On an appearance on MSNBC's "Morning Joe" Wednesday, Trump said the personal financial disclosure forms will be filed Wednesday or Thursday.

"The numbers will be far in excess of what anybody thought," he said. "I built a great company."

What will Trump reveal?

How much the personal financial disclosure form will reveal is uncertain. Personal financial disclosures generally require candidates to list the value of their assets within broad ranges, with "above $5 million" as the top bucket. Many of Trump's holdings, such as Trump Park Avenue in New York, or the hundreds of millions he says he holds in cash, would far exceed that upper limit.

Even if Trump were to include a detailed summary of his assets and debts, skepticism about his net worth will likely remain.

Trump, for example, valued his personal brand and marketing deals at $4.2 billion Canadianwhen he announced his candidacy. Forbes Magazine, however, valued his brand at just $161million Canadian. And that was before Trump's comments about Mexican immigrants cost him business partnerships with companies such as Macy's and Univision.

Trump in the past has taken umbrage at suggestions he might not be as fantastically wealthy as he says. In 2009, he sued author Timothy O'Brien for defamation after O'Brien wrote that Trump's net worth might be as low as $193million Canadian.

Trump lost the suit and a subsequent appeal. In a deposition, the panel of appellate judges noted, Trump conceded that his public disclosures of his wealth depended partly on his mood.

"Even my own feelings affect my value to myself," Trump said.
