A global depository receipt (GDR), also known as international depository receipt (IDR), is a certificate issued by a depository bank, which purchases shares of foreign companies and deposits it on the account. They are the global equivalent of the original American depository receipts (ADR) on which they are based. GDRs represent ownership of an underlying number of shares of a foreign company and are commonly used to invest in companies from developing or emerging markets by investors in developed markets. Prices of global depositary receipt are based on the values of related shares, but they are traded and settled independently of the underlying share. Typically, 1 GDR is equal to 10 underlying shares, but any ratio can be used. The concept was in the news recently. To know why it was in the news, click the above link titled ‘Related News’.
