interesting Blackrock and Fidelity sold 15 million shares..bigger Funds out (just for rules) but MMs ate all the shares..another two good points to consider
1. in the Chapter 11 and next news never mentioned liquidation or restructuration only they money to pay debts (that could answer your question)
2. partner Pacific Rubiales spent $150 million to buy Block Z-1 and then almost $200 million to increase production..today BPZ's market cap is $3.5 million so Pacific Rubiales interest would be keep those doors open..that company market cap is $1 billion!
