Beleaguered electronics maker Sony will cut 2,000 more jobs by March 2013 as the firm continues to restructure its operations to remain competitive in the market.

The electronics giant said the restructuring will cost about $370 million annually from the next fiscal year this coming April, but will likely have a minimal effect on the firm's annual earnings results.

Sony said in a statement that the efforts stem back to April when the struggling firm announced it would kickstart its 'revival' plan by cutting 10,000 workers across its global business, including approximately 3,000 in Japan. The restructuring efforts would cost Sony $926 million during this financial year; a small price to pay for a shot at economic certainty in the near future.

The latest casualty is Sony's Minokamo factory, which produces camera and mobile phone lenses, and also offers customer services for the firm's Sony Mobile division. Sony will transfer some activities out of the Minokamo site but skipped on much of the detail.

Along with the mandatory cuts, Sony is investing in an early retirement scheme that will see around 20 percent of the firm's headcount at its Tokyo headquarters reduced by the end of the fiscal year in the coming April.
