NXP Semiconductors warned that its Q4 sales will be significantly below market expectations. Citing weakening macroeconomic conditions and a deteriorating sales environment, NXP said that based on overall consumer sentiment, recent order book development, and expected future trading levels, it now foresee a 15% to 25% sequential sales decline in the fourth quarter on a business and currency comparable basis. This compares to the previous guidance of an 8 to 14% sequential sales decline as announced on 21 October 2008.http://www.nxp.com
