Les Obamas sont-ils riches?

The White House says the assets held by President Barack Obama and Michelle Obama are valued between $1.8 million and nearly $12 million.

Financial disclosure documents released Monday showed the assets for last year. The couple's assets, which include Treasury bonds and retirement accounts, were valued at a maximum of $7.5 million in 2009.

Assets are listed in wide ranges on the disclosure forms – for example, between $1 million and $5 million – making it difficult to determine their value with precision.

Royalties from Obama's books, "Dreams From My Father" and "Audacity of Hope," totaled between about $1 million and $6 million.
