As the scandal progressed, Enron share prices decreased from US $90.56 during the summer of 2000, to just pennies. Enron had been considered a blue chip stock investment, so this was an unprecedented event in the financial world. Enron's demise occurred after the revelation that much of its profit and revenue were the result of deals with special-purpose entities (limited partnerships which it controlled). This meant that many of Enron's debts and the losses that it suffered were not reported in its financial statements.
