Shares of

GigaMedia

(GIGM) - Get Report

fell 18.1% after the provider of broadband services posted a small third-quarter profit on a 7% sales decline. The company earned $688,000 on sales of $22 million. A year earlier the company posted a loss of $2.7 million on sales of $23.7 million. GigaMedia said the sales decline was due to a general downturn in Taiwan's retail music distribution industry, which impacted its music distribution business. Looking ahead, the company said the general business environment "remains challenging, with continuing weakness in the music distribution market and strong competition in the broadband ISP market." Despite these challenges, it said, it remains confident that it can deliver profitable results. Shares traded down 44 cents to $1.99.
