Nokia's operation profit continued to decline, but it regained a solid cash position in 2013, Finnish Mobile Communications Company Nokia said in its annual report for 2013 released on Thursday. In the last quarter of 2013, Nokia gained 274 million euros (374 million U.S. dollars) of operating profits, 5 percent more than the third quarter. As a mainstay of Nokia after the sale of its mobile phone business to Microsoft, NSN's operating profit was 243 million euros, which slightly decreased by 4 percent at year-on-year level, but rose dramatically by 46 percent from last quarter. Nokia's cash position was strengthened last year. In the end of 2013, the company had gross cash of 9 billion euros, among which 2.8 billion was contributed by NSN, Nokia said in the report.
