Disgraced dot-com tycoon Takafumi Horie slammed his conviction and harsh sentence for securities fraud Sunday, insisting he committed no crimes and that he had more than paid for any mistakes by losing his company.

On Friday, Horie was found guilty of masterminding a network of decoy investment funds to illegally manipulate earnings at his Internet startup, and was sentenced to 2 1/2-half years in prison in the biggest white-collar-crime trial Japan has witnessed in years.

"I did not intentionally attempt to pad earnings, and there was no false accounting," an intent-looking Horie, former president of Livedoor Co., said on a TV Asahi talk show Sunday. "I do not accept the court's verdict."
