May 13 (Reuters) - Online gaming software firm GigaMedia Ltd (GIGM.O) posted a quarterly loss in line with analysts' expectations, but forecast a profit for the first quarter.

For the latest fourth quarter, GigaMedia posted a net loss of $51.7 million, or 95 cents per share, compared with a profit of 9.1 million, or 15 cents per share, a year ago.

Revenue fell 10 percent to $40.3 million.

Year-over-year results showed a decline in the company's gaming software business, which primarily targets continental European markets, the company said in a statement.

Excluding special items, the company posted a loss of 4 cents per share.

Analysts on average had expected a loss of 4 cents a share, excluding special items, on revenue of $36.1 million, according to Thomson Reuters I/B/E/S.

The company forecast first-quarter earnings of 2 cents a share, on revenue of $37.1 million.

The company also said it completed the sale of 60 percent of its online gambling software business to France's Mangas Gaming, and sees a significant one-time gain in the second quarter as a result of the deal.

In December, GigaMedia said it would sell a part of its online gambling software business for an upfront cash payment of $100 million and a final earn-out payment depending upon the fair market value of the business in early 2012. [ID:nSGE5BF0IP]
