Asustek Computer has reported consolidated revenues of NT$33.04 billion (US$1.08 billion) for April 2015, the lowest monthly level since May 2013 with decreases of 21.57% on month and 4.06% on year, and NT$144.930 billion for January-April, inching up 0.11% on year.

Asustek's own-brand sales revenues of NT$29.850 billion for April slipped 22.43% on month and 3.73% on year.

The revenue drop was mainly because notebook and tablet shipments were short of expectations, the company indicated.
