The head of a government-backed corporate turnaround body that will oversee the reconstruction of struggling Japan Airlines Corp. said Thursday that a rescue package is likely to be compiled in January or thereafter.

Hiroshige Nishizawa, president of Enterprise Turnaround Initiative Corp. of Japan, said in an interview that deciding on the rescue plan by the end of the year "will be impossible."

The corporate turnaround body is expected to formally decide to provide support to Japan's top airline after it evaluates the company's assets and inks an agreement with its main creditor banks on a business improvement plan.
