We operate car rental locations at or near airports and in central business districts and suburban areas of major cities in North America (the United States, including Puerto Rico and the U.S. Virgin Islands, and Canada), Europe (France, Germany, Italy, the United Kingdom, Spain, the Netherlands, Switzerland, Belgium and Luxembourg), the Pacific (Australia and New Zealand) and Brazil, as well as retail used car sales locations in the United States and France. We operate equipment rental locations in North America (the United States and Canada) and Europe (France and Spain). We also operate headquarters, sales offices and service facilities in the foregoing countries in support of our car rental and equipment rental operations, as well as small car rental sales offices and service facilities in a select number of other countries in Europe and Asia.
Of such locations, fewer than 10% are owned by us. The remaining locations are leased or operated under concessions from governmental authorities and private entities. Those leases and concession agreements typically require the payment of minimum rents or minimum concession fees and often also require us to pay or reimburse operating expenses; to pay additional rent, or concession fees above guaranteed minimums, based on a percentage of revenues or sales arising at the relevant premises; or to do both. See Note 8 to the Notes to our consolidated financial statements included in this Annual Report under the caption "Item 8Financial Statements and Supplementary Data."
We own three major facilities in the vicinity of Oklahoma City, Oklahoma at which reservations for our car rental operations are processed, global information systems are serviced and major domestic and international accounting functions are performed. We also have a long-term lease for a reservation and financial center near Dublin, Ireland, at which we have centralized our European car rental reservation and customer relations and accounting functions, and we lease a reservation center in Saraland (Mobile County), Alabama to supplement the capacity of our Oklahoma City car rental reservation center. We maintain our executive offices in an owned facility in Park Ridge, New Jersey, and lease a European headquarters office in Uxbridge, England.
