A majority of members on the Liberal Democratic Party's panel on financial matters agreed Friday that it would be difficult to revise the contract allowing the Softbank-led consortium to buy state-run Nippon Credit Bank.

A clause in the contract stipulates that the buyer may sell back to the semigovernmental Deposit Insurance Corp. loans to ailing clients whose market value has dropped 20 percent or move over three years.

Hideyuki Aizawa, who heads the panel, told reporters after the gathering that Japan would lose international credibility should the NCB contract be altered, and stressed that nullifying the contract was not in the best interests of the parties concerned.
