(5)In order to ensure that persons cooperate with an investigation, ESMA should be able to take certain coercive measures. When ESMA has taken a decision requiring a person to bring an infringement to an end, or has requested to supply complete information or to submit complete records, data or any other material, or has taken a decision to conduct an on-site inspection, it may impose periodic penalty payments in order to compel the person subject to the investigation to comply with the decision taken. Before imposing periodic penalty payments ESMA should provide the person the opportunity to provide written submissions.
