Abbreviation: IRG. Swiss federal government institution set up to facilitate investment in developing countries. Investors can use the guarantee to cover certain risks which neither they nor their partners in the recipient country can influence and which they cannot cover in any other way. Under certain conditions, the investment risk guarantee covers inability or refusal to pay on the part of governments and public authorities, as well as the risks of political events or government measures in the recipient country. In Switzerland, the IRG is governed by the Federal Law on the IRG dated 20 March 1970.
