Heavy Hitters

ARNOLD PALMER
$25 MILLION
Since starting Arnold Palmer Enterprises with late IMG founder Mark McCormack in 1960, Palmer's name has been attached to, among other things, batteries, cigarettes, insurance, home furnishings, a lemonade-iced-tea drink, office supplies, rental cars, tires and watches. He has a thriving golf course design business and a car dealership in his hometown, Latrobe, Pa. Endorsements include Rolex, Pennzoil and Callaway Golf.

GREG NORMAN
$20 MILLION
Great White Shark Enterprises, Norman's multinational corporation, dabbles in everything from fine wine to turfgrass, raking in some $300 million annually. The Shark, who is also involved in course design, real estate, apparel, beef production, event management and sports marketing, is said to be worth about $200 million. Less than 7% of that is what he earned on the PGA Tour.

JACK NICKLAUS
$15 MILLION
With more than 290 golf courses in 28 countries, and another 52 under way, he's the world's top course designer. Last year Nicklaus Investments and Nicklaus Design partnered with an investment firm to begin building golf course communities. His PGA Tour event (the Memorial) and endorsement deals (Royal Bank of Scotland, Rolex) keep him visible, helping his apparel and golf club businesses.

GARY PLAYER
$4.5 MILLION
The Gary Player Golf and Safari Experience is just one of the Black Knight's vast array of businesses. On the eight-day trip in South Africa, guests can photograph exotic animals, ride horseback at Player's stud farm in Colesberg, taste wines that he helped to produce and golf on two of his signature courses. His foundation operates a primary school for nearly 500 underprivileged children on his estate near Johannesburg.

PETER JACOBSEN
$4 MILLION
Peter Jacobsen Productions is a one-stop shop for managing golf tournaments, handling marketing, finance, sales and operations. The company has produced more than 250 events, including the Jeld-Wen Tradition in Oregon for the Champions tour and the CVS/pharmacy Charity Classic in Rhode Island. Jacobsen also has a course design business with his swing coach, Jim Hardy.

Off-course income includes estimates of money earned from endorsements, appearances and all businesses that capitalize on a golfer's name but not investment income.
