There are two presentations of FDI statistics: the asset/liability presentation and the directional presentation. Historically, FDI was shown according to the directional principle, which organises the flows and positions according to the direction of investment for the reporting economy—either outward or inward. Therefore, for a particular economy, all flows and positions of direct investors resident in that economy are shown as outward investment, and all flows and positions for direct investment enterprises resident in that economy are shown as inward investment. The presentation of aggregate FDI statistics changed with BPM6 and BD4, both of which recommended that aggregate FDI statistics be shown on an asset/liability basis, which organises FDI statistics according to whether the investment relates to an asset or a liability for the reporting economy. For example, an economy’s assets include equity investment by direct investors resident in that economy in their non-resident direct investment enterprises because those investments are claims that they have on assets in other economies. Similarly, an economy’s liabilities include non-resident direct investors’ equity investment in direct investment enterprises resident in that economy because that investment represents claims that non-resident investors have on assets in the reporting economy. The change to recording aggregate FDI statistics on the asset/liability basis was recommended to make FDI statistics consistent with other macroeconomic statistics in general and with the statistics for other functional categories of investment in the balance of payments and international investment position.
Data presented on a directional basis are better suited to examine the nature and motivations of FDI. The directional principle is the preferred presentation for FDI data broken down by sector and by partner country because it allows for the identification of the main sources and main destinations of FDI. However, under the asset/liability measures, this is not possible because, for example, the acquisition of assets combines both investment by resident parents in their foreign affiliates and loans by resident affiliates to their foreign parents. The directional principle is also helpful for FDI data on an aggregate level, as it sheds light on the motivations behind FDI trends in a timelier manner (as aggregate data are released on a quarterly basis).
