mr. glidden and charges that he may bring against jp morgan chase. we have concerns about the health of the firm, mf global, and the guidance of customer funds. your firm was focused on whether collateral by mf global on october 28 and 29 was paid with customer-segregated funds. according to mr. gibbons, your firm took steps to protect itself and mf global, placing mf global on debit alert. mr. dimon, despite senior attempts by very senior analysts at your firm, including mr. barry zubrow, whether the transfer request was in compliance, mf global did not sign a con fifirmatory letter t your firm demanded. without this signature, jp morgan chase ultimately transferred those funds and accepted the collateral. were you aware of the effort by senior risk management, officer at your firm, to seek compliance confirmation from mf global? >> not at the time i wasn't, no. >> why did jp morgan chase relent on efforts to secure the letter and allow the transfer without written assurance? >> i think the transfer had been made and we were doing a follow-up letter
