OxyChem valuation up ~$3B since Oxy sold. Deal was done in tax inefficient manner. Oxy retained Environmental liabilities. Oxy didn’t try to sell to any other buyers and only negotiated with BRK. They have Vicki pegged as their mark.
This is why Oxy stock is sitting in the mid 50’s with oil at $100/bbl compared to significantly higher when Vicki became CEO and when Oxy acquired Anadarko. Buy high, sell low is not a winning strategy.
