The Reuters source I used to post the info didn't go into much detail. My guess is it's a trade for stock. In other words you owned x amount of AUTH and you'll get x amount of AAPL.
They'll use $8 as the value of AUTH to make the conversion.
And people are willing to pay a slight premium above that to get those AAPl shares.
make sense?
AAPL is up almost 2% today so it's worth a little premium. ;)
