joint letter to shareholders

The joint letter highlights for me some anomalies that I thought should have been addressed and clarified by the signatories to the letter.
These items are
1. "minimal capital commitment " The December 2015 half year report authorised by the Board stated that "total Exploration Expenditure Commitments due after one year but no later than 5 years was $573,436,405 of which $256,162,613 was said to be "non guaranteed work commitments". That left $317,273,792 as firm commitments.
If $317,273,792 is considered by the Board to be "Minimal capital commitment" then what would a major commitment look like? Is the Board in a new "cycle" in which only minimal funds are to be spent? Does this mean the buy back is dead ?
2. "Clear growth strategy". I have yet to see a document that sets out such a vision.
3. "this cycle" . There was no elucidation on how long is this cycle and what is in this cycle ?
4. "the next". Again this refers to the next cycle- when does it start and when does its close?
5. "long Term Value". It would have been useful for the letter to explain what sort of "long Term Value" shareholders might expect in dollar terms per share and over what time frame? For example the Kingdom of Saudi Arabia (KSA) recently indicated that within the long term (which they defined as 50 years) KSA expects to run out of recoverable oil.
Given that possible long term outcome the KSA plan to spent "Trillions" on owning and developing other forms of energy.
