CLIP shows the relation between the sum of the deliveries and excess deliveries compared to the sum of orders and actual backlog by part number for the considered period of time. In aggregation of all part numbers (identifier for production control, calculation, shipment and other purposes products), it shows the status of order fulfillment. Excess delivery (pre- plus over-delivery) for one product (specified by its part number) does not compensate for the backlog of another product.
The definitions for backlog, pre-delivery, over-delivery and excess delivery for a single product are as follows:
- There is a backlog[2] if the sum of the delivery is less than the sum of the commitment.
- There is a pre-delivery if the sum of the delivery is greater than the sum of the commitment and there are orders for the future.
- There is an over-delivery if the sum of the delivery is greater than the sum of the commitment but there are no more orders in the future.
- The excess delivery is the sum of pre-delivery and over-delivery.
To determine the confirmed line item performance two "virtual" quantities are introduced: the virtually committed order and the virtual delivery. The virtually committed order for a product p consists of the actual order for the considered delivery week (DW) plus any backlog of this product accumulated up to that week.
- virtually committed orderp,DW = actual orderp,DW + backlogp,DW
The virtual delivery for a product consists of the actually delivered chips within the considered delivery week plus any excess deliveries of this product accumulated up to that week.
- virtual deliveryp,DW = actual deliveryp,DW + excess deliveryp,DW
The confirmed line item performance of one product p for a delivery week is calculated as the ratio of the virtual delivery to the virtually committed order. If there are more chips delivered than ordered, the CLIP weekly of the respective product is 100%.

×100%
The CLIPweekly of the whole site is calculated as the average CLIPweekly of all products with a virtually committed order. Each product is counted separately (by part number). There is no weighting by volume applied.
