The identified fallouts above mentioned shall be transferred to EB3299 inventory bucket and a report generated at each period end. 3. Assembler shall be responsible to batch the fallouts for transfer from EB3299 to FA6 (Function Area 6) of LOT8 System which is designated for Reclaim processings, or other mutually agreed locale, upon elimination of LOTS System. 4. Assembler shall calculate the Reclaim gain in favor of National on a periodic basis using below Formula or an alternative later agreed between the Assembler and National. Reclaim Gain in favor of National - "Reclaim Pack-out Qty" x Tested Package Cost - (Reclaim Pack-out Qty"/"Reclaim Cum Yld" X Final Test Cost) 5. NSEE will be responsible for minimum quantities of reclaimed mat'ls to be retested at 30K day average. This minimum quantities include the reprocess mat'ls which require black ink and remarked. The minimum number is changeable when both parties agree. Notes: "Reclaim Pack-out Qty" shall mean the pack-out quantity of the reclaimed lots under C-type processing per Engineering Database Report.
