A peek at Donald Trump's finances

Here's why you'll never know how much Trump is worth
Here's why you'll never know how much Trump is worth

There have been many questions surrounding Donald Trump's mysterious but vast wealth.

This week, he filed a 104-page financial disclosure form with the Federal Election Commission. That's 12 pages more than the first financial disclosure form he filed last year with the FEC after declaring his candidacy for the presidency. The form is required by the Office of Government Ethics to be filed by all candidates during their campaigns to help identify, among other things, any potential conflicts of interest should they be elected.

And according to a statement released by Trump on Tuesday, his net worth -- which he's often asserted is $10 billion -- is now more than that. He doesn't specify how much more, however.

It's not possible to assess his net worth from the disclosure form, since he's only required to report a range of values for assets and liabilities.

But here are some things we did learn:

He's worth at least a billion dollars.

...the key words being "at least." That's because the maximum amount required to be reported is "over $50 million." That's not particularly helpful in this case since it could mean anything from $50 million or $50 billion. But a rough tally of the value of Trump's listed assets at the lower end of the reporting range comes to around $1.4 billion. So at least we know he's a billionaire.

Among his largest assets -- those valued at "over" $50 million -- are Fifty-Seventh Street Associates, a commercial real estate firm; Trump Turnberry, a luxury golf resort in Scotland; and Trump International Hotels Management LLC.

He also owes a lot of money.

Trump's assets are impressive, but according to his form, he lists 16 liabilities for which owes at least $315 million. But the true amount of his debt could be much higher, because of the broad reporting ranges.

Five of the liabilities are marked at "over $50 million" each. He also reports nine other liabilities on which he owes anywhere between $5 million and $25 million each.

His golf courses bring in a lot of income.

Trump's total income from January 2015 through mid-May this year was $611 million, not including investment income.

One of the largest sources of his income is his many golf clubs and resorts, which brought in roughly $382 million. He reported earning $132 million from Trump National Doral, $30 million from his Mar-a-Lago club; and between $10 million and $20 million each from many of his other resorts.

What isn't clear from any of Trump's income -- because the form doesn't require candidates to specify -- is whether the numbers reported reflect his income after subtracting the expenses he incurred operating the business, or just the general revenue number before expenses.

He's involved in a lot of businesses

Trump, of course, also derives money from many other business ventures, including, real estate, stocks, licensing and management fees, his modeling and travel agencies, an ice skating rink, and even a beauty pageant.

For instance, he also booked $49.3 million from the Miss Universe pageant, which may reflect his sale of that business.

All told, Trump has a hand in more than 550 ventures. But they're not all businesses he necessarily owns outright. In many he's listed as trustee, shareholder, director or member. He also has a number of licensing deals.

He invests in companies he publicly bashes.

Trump holds many different stocks, including in companies he's publicly attacked. Three of his favorite targets, Amazon (AMZN), Apple (AAPL) and Ford (F), are listed in the document.

Trump has bashed Apple repeatedly for not manufacturing its products in the United States, yet the iPhone maker is his top individual stock holding. Despite attacking Ford for shipping jobs to factories in Mexico, he holds $500,000 of the company's bonds. He even owns a small stake in Amazon, which he slammed for avoided anti-trust regulations.

His books are selling better these days

Though not a huge money-maker relative to his other businesses, Trump also collects royalties from his books, which seem to be selling more these days, given his higher profile.

The Art of the Deal brought in between $50,000 and $100,000, up from the $15,000 to $50,000 reported in Trump's last disclosure. And Time to Get Tough brought in $100,000 to $1 million, up from $50,000 to $100,000.
