gorton: ok. i take it that the parent exxon corporation some time ago made a decision that it was wise corporate policy for it to own its ownership antiship alaskan oil -- and to ship alaskan oil owned by a company or by a subsidiary. mr. rawl: we actually use charter ships many times come also. i do not know how many we are using in alaskan trade, but in international trade exxon has a 19ships worldwide, roughly of them in this country, so we use charter ships. sen. gorton: in any event, this is owned by a subsidiary of a company of which you are ceo. mr. rawl: that is correct. sen. gorton: can you give me the chain of command that would go from you as chairman of the parent corporation down to the subsidiary corporation, or work it back up, who was the captain, his supervisor and so on? mr. rawl: when it gets to the lower levels, i lose track, but the captain has a supervisor. that supervisor presumably, that could be another in between, reports to a manager on the west coast of the u.s. there
