Sony Corp.'s group net profit for the July-September quarter took a 94.1 percent nosedive from the previous year due the massive global recalls of its defective lithium-ion batteries and sluggish sales in its gaming division, the company announced Thursday.

The electronics giant also posted a group operating loss of 20.8 billion yen for the second quarter, a sharp fall from 74.6 billion yen the previous year. Sony's group net profit plunged to 1.7 billion yen on sales of 1.85 trillion yen, which was up 8.3 percent, during the three months. It also posted a pretax loss of 26.1 billion yen, down from 95.4 billion yen in profits.

During the previous second quarter, Sony appropriated 73.5 billion yen in its operating profit due to a change in its pension system, which pushed up the quarterly figure.
