(26)The management report and the consolidated management report are important elements of financial reporting. A fair review of the development of the business and of its position should be provided, in a manner consistent with the size and complexity of the business. The information should not be restricted to the financial aspects of the undertaking's business, and there should be an analysis of environmental and social aspects of the business necessary for an understanding of the undertaking's development, performance or position. In cases where the consolidated management report and the parent undertaking management report are presented in a single report, it may be appropriate to give greater emphasis to those matters which are significant to the undertakings included in the consolidation taken as a whole. However, having regard to the potential burden placed on small and medium-sized undertakings, it is appropriate to provide that Member States may choose to waive the obligation to provide non-financial information in the management report of such undertakings.
