ASRock and Elitegroup Computer Systems (ECS) have reported sequential decreases in consolidated revenues for February 2011 of 37.1% and 30.5%, respectively.

Affected by fewer working days and labor shortages in China, ASRock's consolidated revenues declined to NT$660 million (US$22.46 million) in February from the NT$1.05 billion posted in January. February sales also represented the lowest monthly level since June 2010.

ASRock said it has outsourced some motherboard production to Hong Kong-based Fittec Electronics due to the shortage of workers in China. Fittec has production facilities in China, and its Vietnam plant recently commenced operations.

Fellow motherboard company ECS registered NT$3.31 billion in February consolidated revenues, down over 30% from NT$4.76 billion in January. On an annual basis, however, February sales were up 25.7% from the same period of 2010.

Both ASRock and ECS expect March revenues to rebound following a weak February, and return to a sequential growth track.
