Presumptive GOP candidate Mitt Romney is worth as much as $250 million, according to the candidate's personal financial disclosure filed today with the Federal Election Commission.

While the forms indicate that the candidate could be worth anywhere between $83 and $255 million, a campaign aide offered a more specific range of $190 million to $250 million. This is the same net worth that was reported for the candidate in his 2011 filings.

A review of the documents by ABC News found that Romney earned nearly $190,000 in speaker's fees in 2011, for four speeches including those at Emory University in Atlanta and at Barclay's Bank in Washington, D.C. Last year, Romney reported earning $370,000 for eight speaking engagements but maintained a far less hectic schedule as he was not campaigning full time.

Romney made anywhere from $50,000 to $100,000 in royalties from his book, "No Apology: The Case for American Greatness," a decline from last year, when he reported earning between $100,000 and $1 million from the book. As he has done in the past, Romney donated all profits from "No Apology" to six charities, including the Joey Fund (for cystic fibrosis), Cystic Fibrosis Foundation, Sabin Children's Foundation, National Multiple Sclerosis Society, Dana-Farber Cancer Institute's Jimmy Fund, and Homes for Our Troops.

The documents show that Romney was paid $260,00 in a director's fee for his spot on the board at Marriott. Additionally, Romney was paid between $201 and $1,000 in royalties for a reprint of an oped in The New York Times.

He owns between $250,000 and $500,000 in gold, and the same amount in horses, which are known to be a therapy tool for his wife, Ann, who suffers from multiple sclerosis.

Assets that were sold on behalf of Romney last year include stock in the popular yoga and athletic clothing store Lululemon, software companies Microsoft, Google and Apple, as well as sportswear giant Nike.

"Governor and Mrs. Romney's assets are managed on a blind basis," said spokeswoman Andrea Saul. "They do not control the investment of these assets, which are under the control and overall management of a trustee. The trustee is Brad Malt, a partner at Ropes & Gray law firm."

At least $1 million of Romney's fortune is invested in his son Tagg's company, Solamere Founders Fund.

In addition, the Romneys still maintain a trust for their children and grandchildren valued at roughly $100 million, the campaign said.

The documents also note that while Romney receives money from investments in Bain Capital, the private equity firm he helped to found and has since become a point of criticism by the Obama campaign.

"Since February 1999, Mr. Romney has not had any active role with any Bain Capital entity and has not been involved in the operations of any Bain Capital entity in any way," the documents note.

The investments and profits Romney enjoys from Bain Capital were made as part of his retirement agreement, according to the disclosure forms.
