MIAMI -

Micky Arison remains the richest man in Miami-Dade and Broward counties, according to Forbes.

The money magazine says the Miami Heat owner is the 68th richest man in America with a net worth of $5 billion.

Forbes put out its annual list of 400 richest Americans on Wednesday.

It's been an up and down year for Arison. His team won the NBA title, but his cruise giant Carnival Corp. dealt with tragedy in January when 32 people died after the Costa Concordia rammed ashore in Italy.

Microsoft Corp. co-founder Bill Gates remains the nation's richest man by far with a net worth of $66 billion.
