BERLIN, Jan 25 (Reuters) - Taiwan's GlobalWafers has lowered the minimum acceptance threshold and extended the deadline in a bid to try and save its 4.35 billion euro ($5.3 billion) offer for Germany's Siltronic.

GlobalWafers said in a statement on Monday that the minimum acceptance threshold for the 145 euro per share deal had been reduced to 50% from 65% and extended the acceptance period for shareholders to tender their shares by two weeks until Feb. 10.
