(CNN)Massachusetts Sen. Elizabeth Warren, who is poised to formally kick off her presidential campaign Saturday, has filed her first financial disclosure report as a White House aspirant.
And it shows -- as have past filings during her Senate tenure -- that the populist Democrat is pretty well off.
Warren's assets, tucked away in retirement and investment accounts, range in value from $2.59 million and $8.38 million, according to filings released Tuesday by the Federal Election Commission.
She also has somewhere between $100,001 and $250,000 in her savings account at the First National Bank of Omaha and smaller amounts in savings and checking accounts at other financial institutions.
The filing shows Warren received a $300,000 advance for her book, "This Fight is Our Fight" and still retains the honorary title of emeritus professor at Harvard University, where she once taught law. (Her agreement with her former employer also provides another perk: storage space for "teaching and research materials.")
The financial disclosure reports that all federal candidates and top officeholders file each year offer an incomplete snapshot of their financial standing. For starters, assets and debts are reported broad ranges only.
Candidates also don't have to disclose the value of their homes, if it's a primary residence. Nor does the balance sheet include the $174,000 a year salary earned by most US senators.
Warren, who plans what is expected to be a campaign kick-off event Saturday in Lawrence, Massachusetts, is running on a message of economic populism. She has proposed a 2% tax on Americans whose net worth exceeds $50 million, with an additional 1% levy on billionaires.
