The former CEO of Goldman Sachs and MF Global Holding Ltd, who expressed his sincere apology over the lately-bankrupt commodities brokerage, is expected to testify before the house panel on Thursday following lack of explanations over customer's missing money.

Jon Corzine, the former U.S senator and New Jersey governor said he cannot explain what happened to many hundreds of millions of dollars that the MF global was holding for customers and claimed he had limited access to documents since departure.

The former American politician say he simply do not know where the money is, or why the accounts have not been reconciled to date, This testimony was the first of its kind since the implosion of MF Global.

I sincerely apologize, both personally and on behalf of the company, to our customers, our employees and our investors, who are bearing the brunt of the impact of the firm's bankruptcy, Corzine says in another testimony.
