http://en.wikipedia.org/wiki/High_net_worth_individualUHNWI refers to Ultra-High-Net-Worth Individuals, individuals or families who have at least US$30 million in investable assets.
The number of ultra high net worth individuals worldwide is estimated at about 95,000.
The exact dividing lines depend on how a bank wishes to segment its market; for example, the term Very High Net Worth Individuals can refer to those with assets between $5 million and $50 million, with Ultra High Net Worth Individuals only those with above $50 million.
Most global banks, such as Credit Suisse, Deutsche Bank, HSBC, JPMorgan Chase and UBS, have a separate business unit with designated teams consisting of client advisers and product specialists exclusively for UHNWI.
Because of their extreme high net worth and the way their assets were generated, these clients are often considered to have characteristics similar to Institutional investors.
Brands in various sectors, such as Bentley, Maybach and Rolls-Royce in motoring, actively target UHNWI and HNWI to sell their products.
Figures gathered by Rolls-Royce suggest there are 80,000 people in the UHNWI category around the world.
They have, on average, eight cars and three or four homes. Three-quarters own a jet aircraft and most have a yacht.
