It includes the Herfindahl-Hirschman Index (HHI) which is a benchmark standard used to measure the competiveness in a market. HHI is used by the U.S. Department of Justice and the Federal Trade Commission in reviewing merger and acquisition requests. HHI of less than 1000 means the market is competitive. HHI between 1000 and 1800 means the market is moderately competitive. HHI greater than 1800 means the market is not competitive.
