Nissan Diesel will post a special, pension-related gain of 1.1 billion yen ($US9.3 million) in the business year started April 1, Bloomberg News said, citing a company release.

The truck maker, 45% owned by Nissan Motor and Renault, will gain from returning a portion of its pension obligations to the government following a change in state policy. The company said it will announce its full-year earnings outlook in late May along with its results for the year ended March 31, Bloomberg News said.

The news agency said Nissan Diesel expects to report a group net loss of 3.3 billion yen in the year just ended. The company narrowed its annual loss estimate last month, citing increased demand for trucks with cleaner engines in anticipation of stricter environmental rules to be introduced in Tokyo in October.
