PRONEXUS had been active in fully digital desk-top publishing (DTP) since the 1990s with its own DTP production line and intranet. We welcomed the arrival of Window95 in 1995 and the dawning of the Age of the Internet. In 1999 we took the lead in our industry when we began Internet-based services of confidential client data within a high-security environment. In 2001 we built our own high-security data center designed to cope with fires and powerful earthquakes as part of our infrastructure to support our safe and effective processing, communication and storage of confidential client data. We did this to meet the requirements of the Financial Services Agency's electronic disclosure system and to anticipate its effect on corporate demand for digital services.
In parallel with this infrastructure, we independently developed systems to support the preparation of disclosure documents to meet the requirements of the Financial Services Agency's electronic disclosure system (EDINET). EDINET started in 2001 and became mandatory in 2004. We took the lead in this area with our introduction of our Edits Service in 2003 to help clients prepare disclosure documents. In 2008 we met the new challenges of XBRL (a special computer language used in business reports) in the new EDINET and the introduction of a quarterly reporting system.. We refined our Edits Service and developed it into our PRONEXUS WORKS disclosure support system for clients.
In 2010 we developed and unveiled WORKS-i, an optional system of PRONEXUS WORKS, designed to be a disclosure and accounting information generating system. In 2013 we brought out an improved version of PRONEXUS WORKS designed to meet the upgraded new EDINET system. We enhanced the functions of PRONEXUS WORKS in response to reporting system revisions and continued its development. Over half of all companies listed in Japan use PRONEXUS WORKS as their disclosure platform to ensure the accuracy and efficient disclosure of their disclosure documents. PRONEXUS WORKS functions as a form of disclosure infrastructure.
We are expanding our database business and adding to our suite of services used to build and update IR websites, in response to the ever-greater use of the Internet as a platform for financial and IR information.
