TOKYO- Japan's Sony Corp said its net annual loss will likely be smaller than previously forecast after cost cuts and strong sales of its image sensors and PlayStation video game consoles helped its third-quarter profit beat estimates.

The consumer electronics and entertainment group, which has reported five net losses in the past six years, is in the midst of a restructuring that has so far seen it shrink its struggling smartphone and TV divisions and exit PCs.

Chief Financial Officer Kenichiro Yoshida, appointed in April 2014 to help turn the company around, said the latest earnings showed the restructuring efforts were bearing fruit.

"We said that we will carry through structural reforms, that there would be no sacred cows. It is taking time, but I think we may be starting to see results," he told an earnings briefing. Sony said preliminary results showed its operating profit doubled to 178.3 billion yen ($1.52 billion) in the October-December quarter, while sales rose 6 percent to 2.56 trillion yen.

The third-quarter numbers were not official as Sony could not yet compile accurate figures for its Hollywood studio following a massive hacking of its computer systems. Sony said the incident did not have a material impact on its finances.
