Trump's campaign released a statement on July 15, when he filed disclosure with the FEC, saying it would reveal a "massive" net worth "in excess of TEN BILLION DOLLARS." The report still does not completely detail Trump's fortune, as it deals mostly with ranges.

"For instance, they have boxes once a certain number is reached that simply state $50 million or more. Many of these boxes have been checked. As an example, if a building owned by Mr. Trump is worth $1.5 billion, the box checked is '$50,000,000 or more,'" the campaign's statement said. 

The day of his campaign-launch speech last month, Trump released a one-page report that described his net worth as being approximately $8.7 billion. His campaign said upon filing the disclosure that his net worth has actually increased over the past year. 

"Mr. Trump's net worth has increased since the more than one year old financial statement produced at his presidential announcement," the statement said. "Real estate values in New York City, San Francisco, Miami and many other places where he owns property have gone up considerably during this period of time. His debt is a very small percentage of value, and at very low interest rates. As of this date, Mr. Trump's net worth is in excess of TEN BILLION DOLLARS."
