It is recommended that stewards review and update their methodologies on an annual basis in order to validate their approach to reporting each year and to ensure their data collection processes remain current for their organization.
Stewards are also required to update the brands/affiliates section of their reports each year with the most accurate information, which includes brands for which they are the brand owner or the obligated first importer. Changes in either of these areas will affect quantities reported year over year. During the report validation process, variances may be identified in one or more material categories. If the methodology section clarifies the reason for those variances, it makes the report validation process more efficient for staff and stewards.
