Note they didn't run that 32MM net trade settlement until 30 minutes after they called in the conversion...
So I'm thinking they sold those shares short this morning, then called in the conversion and settled from the new batch. Would make sense because they should have just about run out of their 52MM from last Wednesday yesterday or first thing this morning.
Which would mean that even though they converted another 52MM today, they already have sold 32MM of those, leaving only 20MM to go...
It's gonna be a good August IMO
