The DNRA was first introduced when SGNIC was set up in 1997. Over the years, SGNIC has introduced many services and implemented various schemes. Though the agreement was amended from time to time to reflect these changes, there has been no overall review of the agreement. This revision aims to update the rules and procedures contained within the agreement to reflect present circumstances and practices. It also simplifies the structure, layout and language of the agreement. Our aim is to make the agreement more accessible and easier to understand.
