Number of Terminals and Total Hectares Controlled by the Twelve Largest Port Holdings, 2010
 It is important to underline that in the case of several terminals terminal operators do not own the whole equity, but are in equity sharing agreement with other terminal operators, maritime shipping companies or a local stakeholder such as port authority). Terminal control is allocated to the firm that has the largest equity stake. The results on the above figure should thus be treated with caution as various terminals have various levels of equity stakes and in many cases two major terminal operators have stakes in the same terminal. Terminals where terminal operators have a stevedoring contract are also included.
The sample of terminal operators classified on the above figure accounts for 441 terminals worldwide totaling close to 23,000 hectares (230 square kilometers), which is a sizeable amount of real estate among the world’s most valuable and central locations.
