MEXICO CITY, Feb 23 (Reuters) - Top Mexican broadcaster Televisa is seen posting an 11 percent fall in net profit during the fourth quarter of 2008, hit by higher tax reserves and a steep fall in the value of the peso currency.

According to the average forecast of six analysts surveyed by Reuters, Televisa (TLVACPO.MX)(TV.N) earned around 2.523 billion pesos ($183 million), down from 2.835 billion pesos a year earlier.

The peso fell about 21 percent against the dollar last year, with a large portion of the decline recorded in the last quarter, hit by the global financial crisis and a recession in the United States, Mexico's top trading partner.

The peso's decline hurt the company's financial costs, particularly those related to Televisa's dollar-denominated debt. Analysts also said the company had to set aside more money to meet tax payments.

The Mexican government began a new tax for corporations last year.

Televisa, the world's largest producer of Spanish-language television content, was seen bringing in 13.924 billion pesos in revenues during the quarter, a 12.23 percent increase from a year earlier.

Televisa continued to benefit from the consolidation of Cablemas, a cable company it bought last year, analysts said.

Earnings before interest, tax, depreciation and amortization, or EBITDA, are likely to grow 6.95 percent, according to the survey.

Televisa, whose tear-jerker soap operas have made it a staple in living rooms across the globe, plans to file its fourth-quarter results on Feb. 26 after market close.
