How do file withdrawals, manufacturer withdrawals impact my follow up service fees?
A: All file withdrawals or updates must be made by March 15th, 2012 to avoid the associated annual AMF, ML and AL fees. The March 15th date provides customers with approximately six weeks to perform file maintenance after receiving the annual invoice. The file maintenance could result in an authorized invoice adjustment for AMF, ML and AL Fees.
Any file withdrawals or updates must be made prior to inspections to avoid fees associated with inspections

抓关键点咯，所有文档及发票事宜需要在2012年3月15日前搞定，否则可能会有别的费用产生

同意楼上的解释。
主体的意思就是那样。
