SUMMARY. Put very simply, as a legal or even business document, it's hard to image any document that could be as beset with so many near_crippling legal flaws, traps and pitfalls for its signer, as the LOI. Consequently, it comes as no surprise that in the REAL world of international buying and selling of crude oil, while the crude sellers and their army of sales_obsessed aggressive brokers and agents may generally be infatuated with the idea of having the LOI document widely and routinely used by prospective crude buyers to initiate their purchasing offers, nothing, on the other hand, could be more disliked, more unacceptable or unwanted by most crude buyers, particularly the more credible and substantive lot.
That is about it for the content, believe it or not; it is direct and straightforward without any fluff or nonsense. You are simply covering each detail so the seller knows exactly what the buyer intends to do. Having an informal letter of intent also allows for easy negotiations.
