WorldCo­m took the telecom industry by storm when it began a frenzy of acquisitions in the 1990s. The low margins that the industry was accustomed to weren't enough for Bernie Ebbers, CEO of WorldCom. From 1995 until 2000, WorldCom purchased over sixty other telecom firms. In 1997 it bought MCI for $37 billion. WorldCom moved into Internet and data communications, handling 50 percent of all United States Internet traffic and 50 percent of all e-mails worldwide. By 2001, WorldCom owned one-third of all data cables in the United States. In addition, they were the second-largest long distance carrier in 1998 and 2002.
How the Fraud Happened

So what happened? In 1999, revenue growth slowed and the stock price began falling. WorldCom's expenses as a percentage of its total revenue increased because the growth rate of its earnings dropped. This also meant WorldCom's earnings might not meet Wall Street analysts' expectations. In an effort to increase revenue, WorldCom reduced the amount of money it held in reserve (to cover liabilities for the companies it had acquired) by $2.8 billion and moved this money into the revenue line of its financial statements.

That wasn't enough to boost the earnings that Ebbers wanted. In 2000, WorldCom began classifying operating expenses as long-term capital investments. Hiding these expenses in this way gave them another $3.85 billion. These newly classified assets were expenses that WorldCom paid to lease phone network lines from other companies to access their networks. They also added a journal entry for $500 million in computer expenses, but supporting documents for the expenses were never found.

These changes turned WorldCom's losses into profits to the tune of $1.38 billion in 2001. It also made WorldCom's assets appear more valuable.
