March 4 (Reuters) - Canada’s once mighty telecom giant Nortel Networks , reported fourth-quarter loss, hurt by a non-cash charge arising from an accounting change at its U.S. subsidiaries it had warned about earlier.
The company had said in January that a change in its accounting methods would result in a non-cash charge of $2.2 billion.
Nortel, which filed for bankruptcy in January 2009 and is auctioning off its assets in an effort to pay back debtholders, reported a net loss of $2.3 billion, or $4.57 a share, compared with net earnings of $1.8 billion, or $3.57 a share, last year.
Revenue plummeted nearly 96 percent, to $28 million, with declines year over year in all segments and regions.
Cash balance as of Dec. 31 was $807 million, the company said in a statement.
