Concerns about xxxxxxx business surfaced as early as 1999, when financial analyst xxxxxxxx informed the SEC that he believed it was legally and mathematically impossible to achieve the gains xxxxxx claimed to deliver. According to xxxxxxxx, he knew within five minutes that xxxxxx's numbers didn't add up, and it took four hours of failed attempts to replicate them to conclude xxxxxxx was a fraud.[58] He was ignored by the Boston SEC in 2000 and 2001, as well as by xxxxxxxxxx at the New York SEC in 2005 and 2007 when he presented further evidence. He has since published a book, No One Would Listen, about the frustrating efforts he and his team made over a ten-year period to alert the government, the industry, and the press about the xxxxxxx fraud.
