NEW YORK AP _ A new Associated Press calculation shows that compensation for America’s top CEOs has skyrocketed into the stratospheric heights of pro athletes and movie stars: Half make more than $8.3 million a year, and some make much, much more.

CEOs of companies in the Standard & Poor’s 500 that filed proxy information in the first half of this year received a combined $4.16 billion in 2006, according to AP’s formula.
