There are also a number of events which are recognized by the PGA Tour, but which do not count towards the official money list. Most of these take place in the off season (November and December). This slate of unofficial, often made-for-TV events (which have included the PGA Grand Slam of Golf, the Wendy's 3-Tour Challenge, the Franklin Templeton Shootout, the Skins Game, etc.) is referred to as the "Challenge Season" or more commonly as the "Silly Season."
An organization called the PGA European Tour, separate from both the PGA Tour and the PGA of America, runs a tour, mostly in Europe, but with events throughout the world outside of North America, that is second only to the PGA Tour in worldwide prestige. Several other regional tours are around the world. However, the PGA Tour, European Tour, and many of the regional tours co-sponsor the World Golf Championships. These, along with the major championships, usually count toward the official money lists of each tour as well as the Official World Golf Ranking.
Finally, two events held in Asia after the end of the PGA Tour's current regular season – the CIMB Classic in Malaysia and the HSBC Champions, a World Golf Championships event held in China – became full PGA Tour events, with official prize money, for the first time. Before 2013, neither event had full PGA Tour status despite being sanctioned by the Tour. Wins in the CIMB Classic were not classified as official PGA Tour wins, and HSBC Champions victories were official wins only for current PGA Tour members. Money earned in these events did not count as official PGA Tour earnings for any purpose.
Three of the four majors take place in eight weeks between June and August. In the past, this has threatened to make the last 2-1/2 months of the season anti-climactic, as some of the very top players competed less from that point on. In response, the PGA Tour has introduced a new format, the FedEx Cup. From January through mid-August players compete in "regular season" events and earn FedEx Cup points, in addition to prize money. At the end of the regular season, the top 125 FedEx Cup points winners are eligible to compete in the "playoffs", four events taking place from mid-August to mid-September. The field sizes for these events are reduced from 125 to 100 to 70 and finally the traditional 30 for the Tour Championship. Additional FedEx Cup points are earned in these events. At the end of the championship, the top point winner is the season champion. To put this new system into place, the PGA Tour has made significant changes to the traditional schedule.
Due to increases in prize funds over the years, this list consists entirely of current players. Two players on the list, Vijay Singh and Davis Love III, are eligible for PGA Tour Champions (having respectively turned 50 in February 2013 and April 2014). Both have lifetime exemptions on the PGA Tour for 20 wins and 15 years on the Tour, and Love has won a tournament on the main PGA Tour since turning 50. The figures are not the players' complete career prize money as they do not include FedEx Cup bonuses, winnings from unofficial money events, or earnings on other tours such as the European Tour. In addition, elite golfers often earn several times as much from endorsements and golf-related business interests as they do from prize money.
