Two Sigma Investments’ billionaire founders, John Overdeck and David Siegel, are heading to arbitration after a longstanding feud over the direction of the quant hedge fund.

Two Sigma, which manages more than $60 billion, disclosed the arbitration and a pair of executive departures in a letter to investors Wednesday. The firm said in the letter that it isn’t a party to the dispute and doesn’t intend to share regular updates about it with clients, according to people familiar with the matter.
