CDPs are in U.S. Dollars, exclusive of duties and taxes (e.g. VAT). Prior to shipment, prices may change; TI’s final price on the date of shipment applies.  Forecasts provided in connection with pricing discussions are non-binding on TI.  CDPs are conditioned on adherence to forecast volumes and committed share percentage. CDPs contingent on Start of Production (“SOP”) will begin on the actual SOP date."
