I want to know the answer to the following question:
What range of estimates have been given for Teresa Heinz Kerry's net worth?
All the background I'm provided with is that "This included slightly more than three million dollars worth of H. J. Heinz Company assets, which increased in value by over six hundred thousand dollars in 2013 when Berkshire Hathaway announced their intention to purchase the company.". Is that enough to answer the question?
Answer: no
