Ryan Lillis had a good summary of how the deal is structured.  I’m just going to put together his tweets on this:

On Vivek offer to buy the Kings.  Stern said over $200m placed in escrow, which is 100% of what would go to Maloofs.
$200m is based on 65% of $525m valuation. Ranadive would absorb NBA line of credit and Sleep Train loan, so take that $$ from $341m.
Point is:  Maloofs have seen 100% of $525m valuation offer in escrow from Ranadive group.  But there’s more…
Ranadive has shown NBA he has additional $40m to run the franchise, which is key.  So, as Stern said, he secured $240m for offer.
These are my comments, not Ryan's....
Vivek can pay less out of pocket for the team because he can absorb the arena debt, which is $64 mill.

I'm sure that the Seattle group would have been required to pay that off.  
This means that the Maloofs were using approximately $77 mill of the NBA's credit line.  I wonder if that's a high amount, relative to other teams in the league?
