Every year, Forbes magazine releases its roster of the 400 richest people in the U.S.

Atop the newest list are some familiar names: Bill Gates ($54 billion), Warren Buffett ($45 billion), Lawrence Ellison ($27 billion), and Michael Bloomberg ($18 billion).

There are also a few -- read: 16 -- newcomers: Elaine Wynn, Steve Wynn's ex-wife; and Mark Zuckerberg and Dustin Moskovitz, co-founders of Facebook, among them.

To make the list, you have to be worth at least $1 billion. (Last year, the "price of admission" was a mere $950 million.)

All together, the 400 wealthiest Americans are worth about $1.37 trillion.
