end of the first quarter of such Fiscal Year setting out the actual volume of Product for each Facility for the prior Fiscal Year. In the event that the actual Facility Conversion Costs demonstrate that the then applicable Facility Conversion Cost Threshold has been exceeded, and Manufacturer had not previously adjusted the applicable Price in accordance with this Section 3.2(b) to account for such adjustment, then Manufacturer shall either issue (A) an invoice to Customer for any amounts owed by Customer to Manufacturer or (B) a credit memo for amounts owed by Manufacturer to Customer reflecting the difference between the Price as invoiced and the adjusted Price for such Fiscal Year; provided, however, that any such adjustment made in accordance with the foregoing shall be subject in all cases to the provisions of Section 3.2(b)(iii). For clarity, any amount owed by Customer to Manufacturer or owed by Manufacturer to Customer shall be one hundred and ten percent (110%) of Manufacturer's Conversion Cost, reduced by a 20% allowance for variable costs. Customer shall pay all undisputed amounts due in the currency specified in the applicable Facility Addendum within sixty (60) calendar days from the date of the invoice. If Customer disputes all or any portion of an invoice, it shall be required to pay only the amount not in dispute, and in such event Customer shall notify Manufacturer of the amount and nature of the dispute. Payment by Customer of any amount reflected in any invoice shall not result in a waiver of any of Customer's rights under this Agreement. (c) Notwithstanding the above, the price for Buy-Sell Materials will be updated annually in each year following the first Fiscal Year to reflect one hundred percent (100%) of the full estimated amount of the cost of Buy-Sell Materials to Manufacturer.
