Hollywood, Co Down's Rory McIlroy (26) didn't have the best of years, struggling with injury and a loss of form. But the real money for sport stars lies in endorsements, and Forbes estimates that he is the 12th highest-paid athlete in the world, earning €44.4m before tax and commissions from his sponsors and winnings in 2015.
Much of this comes from the €160m deal with Nike, but he also has lucrative endorsements with Bose, Omega and Upper Deck. He drives a €380,000 Lamborghini Aventador and has a €10m home in Palm Beach, Florida, as well as property in Dubai and Northern Ireland.
McIlroy has switched much of the financial operations of his empire to Ireland. The scale of some of the money involved is mindblowing. Latest accounts for Rory McIlroy Management Services Ltd show the firm placed a $422.13m (€399.55m) book value on the firm's intangible assets connected to the golfer's brand. It doesn't mean he's worth that though, as there was €363m worth of creditors. His advisers may have done an upfront deal to cash in on the value of his brand.
