Methodology: Equilar looked at more than 7,000 officers and directors of public companies who sold stock in 2010, according to Form 4 filings with the Securities and Exchange Commission. "Sold for" amounts represent the total value of stock sold, minus any amount spent to acquire the shares (e.g. exercising options), from January 1 to December 31, 2010. Some sales made under prearranged 10b5-1 trading plans.
