Billionaire Warren Buffett is upping the ante on this year's March Madness challenge.
He's offering $1 million a year for life for any employee who fills out a perfect bracket through the Sweet 16.
All employees of his financial firm Berkshire Hathaway, or its subsidiaries are eligible.
Buffett famously made a similar offer two years ago in which he offered $1 billion to anyone who could pick a perfect bracket, but there were no winners.
