Record year for wealth creation - NBR Rich List

NBR's latest Rich List has been published, and while it included some familiar faces, what has dramatically changed is the total value of the rich listers. It was a record year for wealth creation - for the first time their combined valuation surpassed $100 billion. That's up 26 percent from last year's $80 billion.
