Since 1991, the entity has produced a monthly Club World Ranking.
The ranking takes into consideration the results of twelve months of continental and intercontinental competitions, national league matches (including play-offs) and the most important national cup (excluding points won before the round of 16).
All countries are rated at four levels based upon the national league performance—clubs in the highest level leagues receive 4 points for each match won, 2 for a draw and 0 for a defeat. Level 2 is assigned 3 pts. (win), 1.5 (draw) and 0 (lost), and so on with the next lower levels.
In continental competitions, all clubs receive the same number of points at all stages regardless of the performance level of their leagues. However, the UEFA Champions League and the Copa Libertadores yield more points than minor competitions UEFA Cup and Copa Sudamericana, respectively. The point assignment system is still lower for the AFC, CAF, CONCACAF and OFC continental tournaments. Competitions between two continents are evaluated depending upon their importance. Competitions not organized by a continental confederation, or any intercontinental events not recognized by FIFA, are not taken into consideration.
