'Our full-service solution to the SEC's proposed XBRL mandate has effectively demonstrated time savings, cost efficiency and ease of use. The process for our clients is very straight forward. We complete the initial translation, our client validates the tags, and then we submit the filing. It's a clear and simple process.'

'We look forward to continued market leadership in XBRL through our relationship with RR Donnelley and are more convinced than ever that our relationship provides filers with the best possible market solution as we enter a new era of regulatory reporting,' said Philip Moyer, CEO and President of EDGAR Online. 'Together, we will ensure that XBRL compliance remains simple and reliable.
