President Donald Trump's net worth has fallen over the course of the past year to $2.9 billion, according to a Bloomberg analysis that suggests the commander in chief's slumping New York property values have weighed on his real estate and financial empire.

In particular, Trump Tower and two other major properties in New York have underperformed based on what banks expected when they loaned Trump the money to invest, according to Bloomberg's calculations, which draw on the buildings' financial performance data. Collectively, the three properties have seen their values decline by $380 million over the course of the past year.

Trump's estimated liquid asset holdings have climbed, however, due in part to condo sales and the apparent divestment of his stock portfolio last year. And his debt burden has shrunk slightly in recent months, though it still reportedly sits at $550 million.

The estimate stands in stark contrast to Trump's own assessment of his net worth, which is difficult to verify given the amount of information out there about his financial history. Over the course of the past two years, Trump has said he's worth anywhere from $8.7 billion to more than $10 billion. Given the nature of the real estate business, it's not uncommon for property values to fluctuate year to year. But the upper range of Trump's self-worth is still more than three times what Bloomberg calculated.

Trump, for his part, has previously disputed Bloomberg's calculations, in 2015 telling the Daily Mail that he's worth "much more than $10 billion," that the Bloomberg reporter who spoke with him about the story that year was a "dopey kid" and that perhaps founder Michael Bloomberg "told them to do it" because "he always wanted to do what I'm doing."

"I like Michael so much. But Bloomberg has treated me more dishonestly than probably any other outlet," Trump said at the time, noting that "you don't find [overall net worth] in the statement I filed with the [Federal Election Commission]."

Though the release of Trump's tax returns – which he's hinted he might publish after he leaves office or after an apparent audit has concluded – wouldn't provide all of the answers to his overall worth, they would fill in a few gaps along the way.

Trump did recently publish a public financial disclosure report – a move that was not required of him and that added greater clarity to some of his assets and liabilities. A statement from the Office of the Press Secretary indicated the president "welcomed the opportunity to voluntarily file" the information and that it had been "certified by the Office of Government Ethics pursuant to its normal procedures."

Still, even that document failed to fully flesh out his worth, as specific line items are detailed in ranges instead of exact amounts. And, as Bloomberg pointed out, it appears to mix references to revenue and income. In the accounting world, income typically refers to what's left over after expenses are subtracted from revenues, so the two are not necessarily synonymous.

Trump has not fully divested from his empire, instead turning managerial duties of the business over to his sons, Eric and Donald Jr. The two, along with The Trump Organization CFO Allen Weisselberg, also manage a trust into which the president has funneled his wealth.

Still, even though $2.9 billion is nothing to sneeze at, that doesn't even rank Trump among the 500 richest people in the world, based on Bloomberg's newly updated Billionaire Index . And even if Trump's net worth indeed sits at $10 billion, he'd still just be the world's 131st-richest person.

Microsoft co-founder Bill Gates again tops the list, with a net worth of $89.5 billion. But Amazon CEO Jeff Bezos is closing the gap on the long-running richest man in the world with a net worth of $85 billion. Bezos' net worth increased by nearly $20 billion over the course of the past year – a feat unmatched by anyone in the world over that span.

The 53 year old's company last week announced its acquisition of grocery chain Whole Foods, and just this week it unveiled the Amazon Prime Wardrobe program, which will allow Prime members to order and try on several items of clothing and then ship back what doesn't fit and what they don't want.
