A Multi Currency World
Conventional financial accounting has rules for handling multi-curency financial reporting
TPB note: My experience includes development project accounting where the funding agency (e.g. The World Bank) did its accounting in US Dollars while the country (e.g. Namibia) did its accounting in Rand. Projects in Namibia funded by Sweden had accounting in Kroner for the donor, accounting in Rand for the beneficiary country and accounting in US dollars for international reporting.
The Dollar and the Euro are money that serves as both a medium of exchange and a store of value
TPB note: Other experience included international development finance work in Madagascar where my client company did its accounting in local currency (Malagache francs) but reported in both local currency and international currency (French francs). It was also required to report to the IFC in US dollars. Operations located in Madagascar had expenses in Malagache frans and had local bank finance in Malagache frans. Sales were made mainly in Japanese Yen, Spanish psetas and French francs. Major loan financing was denominated in US dolars (IFC), French francs (CCCE) and in European ECU (European Development Bank).
