Trump: My net worth fluctuates, and it goes up and down with the markets and with attitudes and with feelings, even my own feelings, but I try. Ceresney: Let me just understand that a little. You said your net worth goes up and down based upon your own feelings?

Trump: Yes, even my own feelings, as to where the world is, where the world is going, and that can change rapidly from day to day ...

Ceresney: When you publicly state a net worth number, what do you base that number on?

Trump: I would say it's my general attitude at the time that the question may be asked. And as I say, it varies.
