J.P. Morgan restates results, cites weakness : Report

J.P.Morgan Chase & Co. on Thursday admitted to a "material weakness" in the bank's internal controls in filing its restated first-quarter results, which included the loss resulting from ill-placed investment hedges                               
The company's restated first-quarter profit of $4.92 billion, down $459 million from the original report, matched what the company announced last month                               
In a filing with the Securities and Exchange Commission, J.P.Morgan said it "determined that a material weakness existed in the firm's internal control over financial reporting as of March 31, 2012."
The bank reiterated that remedies had been taken but that "management's internal review" of the matter is ongoing                               
The nation's largest bank by assets had to restate its first-quarter report because losses from its synthetic credit portfolio disclosed earlier this year had unexpectedly impacted results in the quarter                               
When it reported second-quarter earnings last month, J.P.Morgan Chase had said the losses tied to trades known as the London Whale had amounted to $5.8 billion as of July, but that not all the losses were booked in the second-quarter
J.P.Morgan's second-quarter profit was $4.96 billion.
The bank reiterated Thursday that it detected some employees had tried to hide the losses in the first-quarter, and that it therefore had to restate results
