These loans are extended in Turkish liras and subsequently indexed to a foreign currency specified at inception. While the actual currency booked for these loans is Turkish Lira, interest rates will be recorded according to the indexed foreign currency. Both interest and principal are paid at maturity. Both the interest and currency translation gains on these loans are subject to the Resource Utilization Support Fund and Banking and Insurance Transaction Taxes. Unlike export credit, a foreign currency indexed loan is free from export obligation.
