PHI

Since our incorporation in 1949, our primary business has been the safe and reliable transportation of personnel to, from, and among offshore platforms for customers engaged in the oil and gas exploration, development, and production industry. Although in recent years we have entered several new domestic and international markets, a large portion of our offshore flight operations continues to be concentrated in the Gulf of Mexico, where we are a leading provider of such services. Since late 1997, we have also provided air medical transportation for hospitals and for emergency service agencies where we operate principally as an independent provider of medical services. In addition, we perform helicopter maintenance and repair services, primarily to existing customers that own their own aircraft. At December 31, 2018, we owned or operated 239 aircraft domestically and internationally, 125 of which were dedicated to our Oil and Gas segment, 108 of which were dedicated to our Air Medical segment, and 6 of which were dedicated to other operations.
