Despite record revenue, Canadian sports broadcaster Score Media on Thursday swung to a fourth quarter loss on a one-time charge for a future income tax expense.

Toronto-based Score Media, which faces persistent speculation it is up for sale, posted a loss of $316,000 for the three months to Aug. 31, against a profit of $1.1 million in the same period of 2010.

The 2010 Q4 results included a one-time tax recovery of around $1 million, while the latest quarter included an income tax expense of $354,000.

The broadcaster, which includes TheScore TV network, saw fourth quarter revenue jump by $1.1 million to $11.6 million, against  a year-earlier $10.5 million, as Score Media increased its business across TV and digital media platforms.

Fourth quarter EBITDA was $1.9 million, compared to $1.4 million in the same period of 2010.

The full-year 2011 earnings were $1.47 million, down from year-earlier profit of $2.5 million, on overall revenue up $3.9 million to $47.7 million at the year-end, compared to $43.8 million in 2010.

Executives at Score Media, which operates in TV sports, the sweet spot for Canadian broadcasting, declined comment on recent media reports that the broadcaster is up for sale for a rumored $200 million.
