The purpose of this enquiry is to collect data on military expenditure in ordcr to test the applicability of the proposed reporting instrument and to obtail information that would bc of value in the process of further refinement and implcmentation of this instrument. The proposed rcporting instrument is in the form of a matrix whose vertical axis dctails cxpcnditurcs by type of resource costs and whose horizontal axis details cxpcnditures by type of forte groups. Concerning the resource costs,th,he matrix has a pyramidal structurc in order to permit reparting on different levels of aggregation. The vertical axis consists of thrae main cost categories,,namely (1) operating costs; (2) procurement and construction; (3) research and dcvclopmr Rach of these categorics is then disaggregatcd intc diffcrcnt suhcategories andm of the subcategories into sub-subcategories. The figure given for each main category should be equal to thc sum of its respective subcategories and for each subcategory equal to the sum of its respective sub-subcatcgorins. Whsnever applicable, expenditurc data are of course highly desirable on all levels of aggregation. If, however, rcspondents would find it possiblo to supply data only on higher but not on lower levels of aggregation, they are urged notto refrain from participating in thc test but to present their figures on that level~, of aggrcgation which they may find appropriate. I The figures to be reported shall show actual military expenditures for the ) fiscal ysar most closcly coinciding with calendar year 1978, or for the nearest fiscal year available. The amounts shall be reported in the respondent's nationa! ! currency and in current prices - that is, in priccs prevailing in the rcporting year. The unit of measure in which exponditures ere roported may be thc standard
