Foreign Direct Investment (FDI) typically involves a long-term interest and control in a company. However, the definition includes specific instruments and thresholds. Statement 1 and 3 are correct: Foreign Currency Convertible Bonds (FCCBs) and Global Depository Receipts (GDRs) are instruments used by Indian companies to raise capital abroad. Since these are essentially precursors to equity (convertible to shares) or represent underlying shares, they are treated as part of the FDI policy framework and statistics under the "Foreign Investment" category. Statement 2 is correct: Foreign Institutional Investment (FII)—now largely subsumed under Foreign Portfolio Investment (FPI)—is generally considered short-term. However, with certain conditions, it becomes FDI. According to international standards and the Arvind Mayaram Committee recommendations adopted by India, if an FPI holds a stake of 10% or more in a company, it is reclassified and treated as FDI. Statement 4 is incorrect: Non-Resident External (NRE) deposits are simply bank accounts held by NRIs in India. These are classified as External Debt (if repatriable) or Banking Capital, not foreign investment in a productive enterprise.
