Before the Bell - Google dips more after Microsoft's Yahoo bid

NEW YORK (Reuters) - Google shares traded lower in premarket trading on Friday after Microsoft unveiled a surprise bid for Yahoo.

The drop took Google down an additional 1.7 percent from its last level in Thursday's post-market session when Google slumped 6.5 percent following disappointing earnings.

Google shares slipped to $518.01 ahead of the opening bell after ending Thursday's extended session at $527.40. Google, which is Yahoo's arch rival, fell hard after the close Thursday when it reported quarterly earnings that missed analysts' estimates.

Google ended Nasdaq's regular session at $564.30.
