At the same time, these data are cross-checked with information contained in reports transmitted byMorocco’s aforementioned airline to the Department of Foreign Trade Statistics of the Office of Exchange for balance-of-payments purposes. These reports specify the transaction (importation) financing modalities. In this respect, it should be added that the airline company sometimes uses leasing for its acquisitions of planes.
