Rory McIlroy is worth more than $400 million

Hey, remember when Rory McIlroy said the FedEx Cup's $10 million first-place prize didn't really mean all that much to him?

Yeah, he wasn't kidding.

The four-time major champion is valued at $422 million, according to documents filed by his eponymous management company. Rory McIlroy Inc., which McIlroy formed in October 2013 after prematurely leaving former management firm Horizon Sports Management, values the Ulsterman at that nearly half-billion-dollar figure based on his on-course earnings, as well current endorsements with Nike, Bose, Omega and others.

Despite having a home in Florida, McIlroy's management firm is based in Dublin. In documents filed by the company, McIlroy's primary residence is listed as being in Dubai.

The 26-year-old would seem well on his way to becoming golf's second-ever billion-dollar player, joining Tiger Woods, who was recently valued by Forbes at over $700 million.

McIlroy is done for 2015, wrapping up a four-win year with a victory at the European Tour's DP World Tour Championship and capturing its season-long Race to Dubai for the third time in four years.
