JP Morgan Chase has reached an agreement with the trustee of Lehman Brothers to return around $800 million in Lehman customer assets to the estate of the bankrupt firm, for distribution to its customer claimants.

The returned assets will largely be from cash and securities from Lehman Brothers accounts held at JP Morgan, which had been set aside pending a resolution with the trustee. JP Morgan said there would be no material financial impact from the transaction.

The agreement remains subject to approval from the United States Bankruptcy Court of the Southern District of New York.

There was some dispute between the two firms over whether JP Morgan had the right to keep the funds as general collateral, but it was agreed most of the funds belonged to Lehman customers, the Financial Times reported, citing a court filing. In a statement, the trustee said JP Morgan had taken a “constructive approach” to resolving the matter.

According to the news report, the Lehman trustee has collected around $22 billion against some $75 billion of claims, and is still pursuing claims against Lehman's parent company along with its UK affiliate, Lehman Brothers Europe. The dispute with the UK affiliate reportedly relates to around $30 billion in assets which the trustee says belongs to the customers.
