strategy

I heard from another source that PSA directors have build up strategy to not to over produce and that way prolonging life, their life also, use of the reserves for at least 30-years. No Director has bought shares and they are least bothered of share price. They will restrict their eps to 15-20cents pa.
I strongly concur with this view because looking from their activities since 2004 GoM is in production but restricted production.
Who has got opinion on this....
