(Bloomberg) -- Millennium Management demanded a number of significant changes at Weiss Multi-Strategy Advisers as part of failed talks to take over the troubled hedge fund, including firing all but five portfolio managers, winding down the firm’s core staff and kicking out client cash.

The details were included in email correspondence made public Friday as part of Weiss’s bankruptcy proceedings. The negotiations took place in late February, and ultimately fell apart when Millennium walked away. Weiss went on to file for court protection in April.

Millennium also sought to control Weiss’ finances and wouldn’t take on any existing liabilities other than some obligations to strategic partner Leucadia Asset Management, according to a Feb. 22 email from Millennium Chief Strategic Development Officer Mark Meskin to Weiss founder George Weiss and deputy Chief Investment Officer Mike Edwards. Millennium founder Izzy Englander was cc-ed on the email.

Millennium also asked that Weiss Chief Investment Officer Jordi Visser step down, the emails shows. Bloomberg previously reported the request. Millennium also wanted new contracts to be drawn up for portfolio managers that included protections for the firm, and asked for “additional protections” related to portfolio manager departures.

A representative for Millennium declined to comment. Spokespeople for Weiss and Leucadia didn’t respond to requests seeking comment made after regular business hours.

The slew of details offers a rare glimpse into deal negotiations between hedge funds, which have become more frequent as industry giants get bigger and seek external firms to run their cash and optimize costs. Last year, Millennium held talks with Schonfeld Strategic Advisors, and asked the firm to return client capital and run Millennium cash instead. Those talks fell through.

Millennium offered to provide Weiss as much as $30 million to repay Leucadia, an affiliate of Jefferies Financial Group, and obtain a “full release” of any future obligations, emails show. It also offered to give Weiss $25 million to use as retention payments for portfolio managers.
