Five billionaires who live in Orange County, and three executives who made their fortunes in O.C., are included in Forbes’ 32nd annual list of the 400 richest people in America.

 

Our eight Forbes 400 list members are worth a total of $33.9 billion, which is $4.5 billion more than they were worth last year. Six of them got richer, but not all of the gains were large enough to keep pace with the rest of the list. Only three gained ground in the Forbes 400.

Henry Nicholas, the co-founder of Irvine-based semiconductor maker Broadcom, was the only O.C. rich person to fall off the list. He retired 10 years ago, but his wealth is tied to the company he founded, and Broadcom shares dropped 28 percent in the last year. That brought his net worth down to a measly $1.15 billion, below Forbes’ $1.3 billion minimum.
