MEXICO CITY, Oct 23 (Reuters) - Mexico's largest

broadcaster Grupo Televisa swung to a loss in

the third quarter after a deferred tax write-off boosted income

taxes, according to a filing to Mexico's stock exchange

published on Thursday.

The broadcaster, the world's biggest producer of

Spanish-language content, posted a net loss of 1.93 billion

pesos ($105.43 million), much greater than the $12 million

dollar-denominated loss forecast by analysts polled by LSEG.

The loss, which follows a net profit of 666 million

pesos in the same quarter last year, was driven primarily by a

non-cash deferred tax asset write-off of $2.66 billion related

to capital tax losses, Televisa said.

The company also credited the loss to reduced profit

contributions from associates and joint ventures like its one

with U.S. Spanish-language broadcaster Univision.

The company's revenue fell 4.8% from a year earlier to 14.63

billion pesos ($798.7 million), close to analysts' forecast of

$771.5 million, according to LSEG data.
