According to the WSJ:
Och-Ziff Capital Management LLC "likely disseminated and/or was the recipient" of an inaccurate rumor that Lehman had spun off debt to two Lehman-controlled hedge funds to reduce the investment bank's leverage, according to the filing. Investors were focused on Lehman's debt levels in the months before its failure.
The rumor was one of many "lies" spread by unscrupulous market participants looking to profit from shorting the troubled investment bank's stock, alleged the filing, made on Wednesday by lawyers investigating Wall Street firms on behalf of Lehman's bankruptcy estate.
Ah yes, all those "lies" that everybody was spreading that the investment bank was insolvent and wasn't going to make it and would wind up bankrupt. Those crazy crazy untrue rumors that the investment bank was lying about its leverage ratio, its liquidity, the value of the assets on the balance sheet etc. etc. And now, we must expose those rumor-mongerers in bankruptcy court after said firm has gone bankrupt. How come nobody is subpoenaing all the real lies from all the investment pros that insisted the firm was solvent and cheap at $15 per share?
