What happened

Shares of InvenSense Inc. (NYSE:INVN) jumped 17.6% Wednesday after the motion-sensing chip specialist agreed to be acquired by Japan's TDK Corp. (OTC:TTDKY).

So what

More specifically, TDK will acquire all outstanding InvenSense shares for $13.00 per share, representing a 19.9% premium to yesterday's close and a total acquisition price of $1.3 billion. TDK will finance the transaction with cash on hand.

But that premium is even greater -- 52.4% above its 60-day volume-weighted average trading price as of yesterday's close -- when you account for the fact that InvenSense stock already jumped almost 30% in a single day earlier this month, after reports of TDK's interest first surfaced. At the time, sources speaking to Reuters suggested TDK had offered InvenSense $12 per share.

Now what

Both companies' boards of directors have unanimously approved the deal. Assuming it also receives the stamp of approval from both regulators and InvenSense shareholders, the acquisition is expected to close in the second quarter of the fiscal year ending March 31, 2018.

In the end, though, I see little preventing this deal from going through. So with shares trading within 2% of the agreed acquisition price -- and unless holding longer would ensure more favorable long-term capital-gains tax treatment -- I think InvenSense investors would be wise to take their profits and put them to work elsewhere.
