Investment in Variable Interest Entity | 11. INVESTMENT IN VARIABLE INTEREST ENTITY We account for our investment in our West African operations as a variable interest entity, which is defined as an entity that either (a) has insufficient equity to permit the entity to finance its operations without additional subordinated financial support or (b) has equity investors who lack the characteristics of a controlling financial interest. As of September 30, 2016, we had a 49% investment in the common stock of PHI Century Limited (“PHIC”), a Ghanaian entity. We acquired our 49% interest on May 26, 2011, PHIC’s date of incorporation. The purpose of PHIC is to provide oil and gas flight services in Ghana and the West African region. For the quarter ended September 30, 2016, we recorded a loss in equity of unconsolidated affiliate of $0.2 million, compared to a loss of $0.1 million for the quarter ended September 30, 2015, relative to our 49% equity ownership. For the nine months ended September 30, 2016, we recorded a loss in equity of unconsolidated affiliate of $0.3 million, compared to a loss of $0.2 million for the nine months ended September 30, 2015, relative to our 49% equity ownership. We had $0 of trade receivables as of September 30, 2016 from PHIC. At December 31, 2015, we recorded an allowance for bad debts against this trade receivable of $1.5 million, as we do not anticipate that we will be able to recover them. Our investment in the common stock of PHIC is included in Other assets on our Condensed Consolidated Balance Sheets and was $0.9 million and $0 at September 30, 2016 and December 31, 2015, respectively.
