OPINION: So was it determination or desperation that led to Occidental Petroleum paying $57 billion to buy Anadarko?

Oxy chief executive Vicki Hollub admits to being no merger and acquisition expert, but says it was definitely determination.

The first woman to head up a major US oil company is upbeat but she still has to convince all shareholders.

They do not have a say on the deal and some used the Oxy annual general meeting to vote against re-electing board executives.
