Jon S. Corzine, MF Global Holding Ltd.'s chief executive officer, gave "direct instructions" to transfer $200 million from a customer fund account to meet an overdraft in one of the brokerage's JPMorgan Chase & Co. accounts in London, according to an e-mail sent by a firm executive.

Edith O'Brien, a treasurer for the firm, said in an e-mail sent the afternoon of Oct. 28, three days before the company collapsed, that the transfer of the funds was "Per JC's direct instructions," according to a copy of a memo drafted by congressional investigators and obtained by Bloomberg News.

O'Brien's internal e-mail came as the New York-based broker found intraday credit lines limited by JPMorgan, the firm's clearing bank as well as one of its custodian banks for segregated customer funds, according to the memo, which was prepared for a March 28 House Financial Services subcommittee hearing on the firm's collapse. O'Brien is scheduled to testify after being subpoenaed this week.
