LJM was one type of independent ghost-entities company Andrew Fastow used in the Enron scandal.
LJM, which stands for Lea, Jeffrey, Matthew, the names of Andrew Fastow's wife and children, was a company created in 1999 by Enron's CFO, Andrew Fastow, to buy Enron's poorly performing stocks and stakes and bolster Enron's financial statements. 
Andrew Stuart Fastow (born December 22, 1961) is a convicted criminal and businessman who was the chief financial officer of Enron Corporation, an energy trading company based in Houston, Texas, until he was fired shortly before the company declared bankruptcy. 
 By unlawfully maintaining personal stakes in these ostensibly independent ghost-entities, he was able to defraud Enron out of tens of millions of dollars.
