In the last personal finance report he filed as vice-president, Gore disclosed on May 22, 2000, that the value of his assets totalled between $780,000 and $1.9 million. In addition, Gore listed an interest in his father's estate that included Occidental Petroleum Corp. stock worth as much as $1 million.

Now Gore charges a $175,000 speaking fee and has a net worth “well in excess” of $100 million, including pre-public-offering Google stock options, according to an article in Fastcompany.com last year. Kreider said the speaking fees vary and Gore doesn't disclose them.
