Market Reporting
MSA reports include regular publications such as the MSA’s Annual Report, Year in Review and Quarterly Report, which serve to provide information on market events, trends and observations concerning the fair, efficient and openly competitive operation of the market. Other reports deal with special events, such as investigations. Reports are typically accompanied by a Notice which provides summary information about the content and the motivation behind releasing the report.
