For Oil Companies $110 Billion Debt Wall Looms Over Next 5 Years

``The pressure on oilfield services companies will only increase through 2021, when nearly $29 billion of bonds and loans are expected to come due. Much of the maturing debt was issued between 2011 and 2015, when U.S. drilling was at a record high fueled by strong energy prices and new technologies. Moody's expects that more than one-third of the analyzed companies will be carrying debt loads that are more than 10 times higher than earnings this year.''
