To quote from the June 30th, 2004 release: "The U.S. net international investment position at yearend 2003 was a negative $2,430.7 billion (preliminary) with direct investment valued at current cost, as the value of foreign investments in the United States exceeded the value of U.S. investments abroad." My own guess is that we will be south of there, hopefully not by too much.
