The Dow Jones Islamic Market Index (DJIMI) was established in 1996. The Index has been approved by Fiqh Academy of the OIC. It uses three levels of screening—eliminating businesses involved in activities not allowed by Islamic law (alcohol, pork, gambling, prostitution, pornography, etc.); eliminating companies whose total debts divided by their 12-month average market capitalization are 33% or more of their total sources of funds; eliminating companies that have `impure income or expenditure` (including, of course, interest) of more than 5-10 per cent of their income or expenditure (eliminating businesses with "any" `impure income` being considered impractical).
