The document discusses the depository system in India. It notes that the need for a depository system was realized after irregularities in securities transactions in 1992 exposed limitations of the existing system. The Depositories Act was passed in 1996 to provide a legislative framework for dematerialization and book entry transfer of securities. This established the National Securities Depository Limited as India's first depository, which began operating in 1996. The depository system functions similarly to a banking system, holding securities electronically for clients and allowing transfer of securities via written instructions.
