Despite repeated claims from Donald Trump that he is personally worth more than $10 billion, a new Securities and Exchange Commission (SEC) filing shows that the Republican party's presumptive presidential nominee was worth less than half that amount as recently as 2011.

According to a 2012 document filed to the SEC by Wells Fargo Securities on Trump's behalf, Trump was worth just $4.2 billion.

"As of June 30, 2011, Mr. Trump reports a net worth in excess of $4.2 billion and liquidity in excess of $250 million," reads the 132-page filing, in a section on Trump Tower in New York.

The accuracy of the filing, first reported Saturday by The Guardian, was confirmed by a Wells Fargo spokeswoman.

"Obviously, if it was inaccurate, we wouldn't have filed it with the SEC," Wells Fargo's Jessica Ong told the Guardian.

The report comes on the heels of recent scrutiny over the lackluster state of Trump's campaign finances. According to a Federal Election Commission report, by the end of May, the campaign had just $1.3 million cash on hand, compared to Clinton's $42 million stockpile in that time period.

Last week, Trump said he "fully extinguished (terminated)" the reported $50 million loan he personally made to fund his primary campaign.
