WASHINGTON (TIP): President Barack Obama and first lady Michelle Obama reported assets worth between $1.8 million and $7 million for last year, little changed from their previous year’s holdings, according to financial disclosure forms released on May 15. The forms, required by law, permit public officials to list their assets in broad ranges.

As a result, a precise net worth is difficult to ascertain. The forms show the largest jointly owned assets by the president and the first lady were Treasury notes worth between $1 million and $5 million. While the value of their assets is certainly higher than that of most Americans, their mix reflects the financial demands of a 50-something couple with two daughters. Their assets include Vanguard retirement funds and college savings plans.
