July 27 (Reuters) - Online content delivery company Level 3 Communications Inc posted a wider-than-expected quarterly loss, hurt by higher expenses, sending its shares down 5 percent in trading before the bell.
Level 3, which operates Internet backbone networks spanning North American and Europe, lost $181 million, or 11 cents a share, in the second quarter. It lost $169 million, or 10 cents per share, a year ago.
Excluding costs associated with its acquisition of smaller rival Global Crossing , Level 3 lost 10 cents a share.
Revenue rose 3 percent to $932 million. Total expenses rose to $180 million from $141 million, in the year-ago period.
Analysts, on average, expected a loss of 9 cents a share, excluding items, on revenue of $977.4 million, according to Thomson Reuters I/B/E/S.
In April, Level 3 said it would buy Global Crossing for about $1.9 billion in stock to strengthen its fiber optics networks business and expand into Europe and Latin America.
Shares of the company fell to $2.12 in trading before the bell on Wednesday. They closed at $2.23 on Tuesday on Nasdaq. (Reporting by Supantha Mukherjee in Bangalore; Editing by Joyjeet Das)
