During Bank of America Corp.'s appearance in the insider trading trial of Segantii Capital Management, a prosecution witness revealed the bank lacked a formal block trade mandate for Esprit Holdings Ltd. when engaging in phone calls with the hedge fund about the potential deal. This testimony emerged as a key piece of evidence challenging the nature of communications between the financial institutions.

The absence of a formal mandate raises questions about the legitimacy of discussions between BofA and Segantii regarding Esprit Holdings. In insider trading cases, the context and purpose of communications between potential dealmakers and investors often determine whether information sharing crosses legal boundaries. The prosecution appears to be building a case suggesting improper knowledge exchange.

The revelation potentially undermines Segantii's defense that communications with BofA were part of normal market discussions. The hedge fund faces allegations of trading on non-public information, and this testimony about the bank's lack of formal mandate could strengthen the prosecution's argument that the discussions went beyond standard market practices. The trial continues with both sides presenting their interpretations of these communications.
