Dear Sales Manager

Please find attached performance for last month. These scores are developed using four fundamental categories:

These ratings are extremely important to Webasto Roof Systems because it is a reflection of your credibility as an approved supplier and will be used by Purchasing as a tool when sourcing new business. Attachment “A” indicates how the scores are calculated, which is attached for your review. Please note the percentages have changed for PPM’s and premium freight instances.
