Obamas" 2011 assets valued at as much as $8 million, financial disclosure forms show Democrats may be united in their 2012 campaign focus on "economic fairness," but new financial disclosure forms show that for Barack Obama, it pays to be a president who has penned several best-selling books. President Obama and Vice President Biden. M. Spencer Green/AP According to disclosure forms released Tuesday by the White House, the Obamas in 2011 held total assets ranging from $2,566,000 to $8,265,000. That's more than 10 times the total assets reported by Vice President Biden and his wife, Jill, in 2011. The Bidens reported assets ranging from $233,000 to $776,000. The range of the Obamas" total reported assets is changed - although not necessarily down - from 2010, when the first couple's disclosure forms showed assets from $2.8 million to $11.8 million. The lack of a specific dollar figure stems from the fact that the forms require only that assets be reported within broad ranges. The forms show that the Obamas made anywhere from $250,000 to $2.1 million in book royalties in 2011. "Dreams from My Father" and the children's book "Of Thee I Sing" each accounted for $100,000 to $1 million; and "The Audacity of Hope" accounted for $50,000 to $100,000. The Obamas" assets also include anywhere from $500,000 to $1 million held in a JPMorgan Chase checking account. The bank is under heightened scrutiny this week, as the Department of Justice is launching a criminal probe into the firm after reports of its staggering $2 billion trading loss. Biden, by contrast, has from $2,000 to $30,000 in two savings accounts and $2,000 to $32,000 in four checking accounts, the forms show. The Bidens also had income of from $15,000 to $50,000 from a residential rental property in Wilmington, Del. In past years, the Obamas have reported gifts such as Bo - the $1,600 Portuguese water dog given to the first family by the late Sen. Ted Kennedy (D-Mass.) - and the $1.4 million cash prize that accompanied Obama's 2009 Nobel Prize win. The cash was donated to charity. This year, Obama reported no gifts. Biden in 2011 reported one gift - a Vulcain Cricket watch given to him by Keijo Paajanen of Helsinki, Finland. According to the site Hodinkee, Biden was spotted wearing a Vulcain Cricket watch late last year. The disclosure form lists the value of the watch as $800.
