Linklaters and Davis Polk have advised on a settlement agreement in the Lehman Brothers bankruptcy which will see $9bn (£6bn) of assets returned to the defunct bank’s customers, in what administrator PwC has described as “a landmark moment” in long-running insolvency proceedings.

The settlement and distribution plan concerns Lehman Brothers International (Europe)’s (LBIE) dealings with Lehman Brothers Inc (LBI), and the complex intercompany claims and liabilities between the parties.
