(8)Pricing policies and procedures should be provided on an ongoing basis so that any material changes are reported without undue delay after their adoption and at the latest 30 days after their implementation. The information to be reported should be compiled in a standard format to allow ESMA to receive and process the records automatically in its internal systems. Due to technical difficulties and technical progress over time, a number of technical reporting instructions concerning the transmission or the format of the files to be submitted by registered credit rating agencies might have to be updated and communicated by ESMA through specific communications or guidelines.
