AAWW has a 51% equity interest and 75% voting interest in Polar. DHL Network Operations (USA), Inc. (“DHL”), a subsidiary of Deutsche Post AG, holds a 49% equity interest and a 25% voting interest in Polar. Polar is a variable interest entity that we do not consolidate because we are not the primary beneficiary as the risks associated with the direct costs of operation are with DHL. Under a 20-year blocked space agreement, which began in 2008, Polar provides air cargo capacity to DHL. Atlas has several agreements with Polar to provide ACMI, CMI, Dry Leasing, administrative, sales and ground support services to one another. We do not have any financial exposure to fund debt obligations or operating losses of Polar, except for any liquidated damages that we could incur under these agreements.
