Isuzu Motors Ltd. reported a wider-than-forecast loss for its just-ended business year as it wrote down the value of deferred tax assets.

Japan's largest maker of light-duty trucks had a net loss of about ¥26.9 billion for the year ended March 31, compared with an earlier estimate of a ¥15 billion loss, it said in a statement Tuesday. That compared with profit of ¥76 billion a year earlier.

The company's sales plunged 26 percent as demand for trucks dropped in Japan, Russia and the Middle East. Tokyo-based Isuzu will pay ¥24.5 billion more in taxes than it had expected after the writedowns.
