Central Securities Depository Of IRAN




The Integrated Portal of Electronic General Meetings (DIMA) has been developed to provide the shareholders in the Iranian capital market with easy electronic access to the general meetings (GMs) of the listed companies and those registered with the Securities and Exchange Organization of Iran (SEO) in a secure environment with no geographical limitations. This is while prior to DIMA all shareholders were required to be physically present at the GMs costing them considerable time and energy. 

DIMA platform is a neat solution satisfying all requirements for holding GMs virtually, including necessities before, during, and after meetings. 

DIMA platform started to serve in 2020, and currently, all Iranian legal and natural investors are able to receive DIMA services easily.
