Dear student,
Global depository receipt are usually used by corporates or multinational companies as a source of finance for their company. They borrow money using this financial instrument in rupees or in foreign currency. The company issues their shares to a depository bank in local currency. The bank issues depository receipt in return for this. Such depository receipts converted to the value of foreign currency is known as GDR.
A European depository receipt is issued for shares of non European company which are traded in European financial markets.
Companies use GDR as a source of finance to borrow money in foreign currencies such as US dollars,Euro etc.. If the company tries to get borrowings in Euro instead of US dollars then in such situations GDR are termed as European depository receipt.
If a European company wants to raise funds from Indian financial market then they can make use of Indian depository receipts.
An Indian depository receipt is a financial instrument which has its value in terms of Indian rupees.It is issued to enable foreign companies to borrow money from Indian financial market.
