Facebook "Paid" $715 Million in the Billion Dollar Instagram Acquisition

Instagram made quite a splash when it sold for "one billion dollars" to Facebook a few months ago. In fact, as the IPO was drawing closer, the sum continued to grow, since the largest amount was "paid" in Facebook shares. Which, as we all know, became worthless immediately after the IPO.

But they're on the recovery now, having gained 20 percent in one day due to a positive outlook on mobile revenue from Facebook.

So that would mean the acquisition price is on the up again. And it does, though that's mostly hypothetical now, as Facebook has already figured out the figure it's going to put in its books, $521 million, €402 million .

That's from $300 million, €231 million in cash and some 12 million vested Class B shares. Facebook also issued some 11 million shares to Instagram employees which had stock in Instagram, but those are unvested yet.

Those have been given a value of $194 million, €150 , though their real value may as well rise before employees can sell them.
