According to a report from the Financial Times, Paulson & Co, a hedge fund that made billions of dollars betting against subprime mortgages, has received a request for information from the Securities and Exchange Commission in connection with an investigation into complex securities at the heart of the financial crisis, according to people familiar with the matter. In the months prior to the real estate crash, which pre-empted the global economic volatility, the company made $15 billion from investments in subprime deals.
