Income before taxes was Euro 140 million and net income was Euro 55 million, which represent year-on-year improvements of Euro 94 million (204%) and Euro 12 million (28%) respectively. The company experienced a strong quarter led by consumer demand for the V800 series and Z1010 3G UMTS phones, as well as GSM models like the S700, K700 and K500 series. During the quarter Sony Ericsson increased investment in brand and product development, while the Average Selling Price (ASP), one of the highest in the industry, increased sequentially to Euro 160. "2004 was a good year for Sony Ericsson as the company established profitability and entered into a growth phase in its development," said Miles Flint, President of Sony Ericsson. "The fourth quarter continued a trend of expansion in both volume and sales, showing the company's ability to effectively compete in this dynamic market. Strong growth in Q4 was led by good up-take of our latest 3G UMTS phone which has laid the groundwork for future expansion of our 3G portfolio." During the fourth quarter, Sony Ericsson launched a new entry-level GSM product, the J200, for the Asia Pacific and Chinese markets, and introduced the Vodafone V800 and V802SE UMTS phones for the global and Japanese markets.
