[1] The order to issue arrest warrants for O'Hara and Perez was signed on November 12, 2009 by federal magistrate judge Debra C.

[1] At their bail hearing, federal prosecutor Preet Bharara said: "The computer codes and random algorithms they allegedly designed served to deceive investors and regulators and concealed Madoff's crimes."

[4] The FBI and SEC said that later in August or September 2006, O'Hara and Perez withdrew hundreds of thousands of dollars from their personal BLMIS accounts before informing Madoff that they no longer wished to lie for him.

[2] Allegedly, Madoff and others created statements for the "Split Strike clients" that listed stocks in which their funds were supposedly invested.

Data related to chosen baskets of securities would be entered into an IBM AS/400 server known as "House 17", which was dedicated primarily to the IA business.

Madoff, DiPascali, and others used computer programs that were allegedly written by O'Hara and Perez to allocate pro rata multiples of the chosen basket, based on clients' purported account balances with BLMIS.

These programs would output thousands of pages of fake documents that purported to confirm the purchase of stocks from the chosen basket.

Allegedly, Madoff, DiPascali, and others oversaw the production and mailing of thousands of pages of account "statements" each month, which all falsely reflected securities transactions that had not occurred.

According to the FBI, they would also routinely add lines representing additional, fictitious option trades for the purpose of making it appear that the accounts had achieved the targeted rate of return.
