In what country did Unocal incorporate? From which country does Unocal receive the tax benefits of incorporation?

I think Unocal was originally incorporated in the U.S. (Unocal stands for Union Oil of California, I believe).

But that has nothing to do with where its assets are located. The U.S. government has no legitimate role in overseeing the ownership of a company's assets overseas.

The refinery is located in El Segundo, California, just south of LAX and adjacent to a USAF base.
