A representative for Finch Bay declined to comment.

Markel, who will act as the company's CIO, is co-founding the activist fund with former ValueAct portfolio manager Daniel Urdaneta, the sources said.

The fund will take activist positions in companies but will also hedge its positions to protect the fund's performance against market risk and is therefore calling itself market neutral.

It will focus on corporate strategy for mid-sized companies in Europe and the U.S. typically with market caps of over $1 billion.

The focus would be this rather than management change, said a person close to the matter.

Thierry Vanlancker, who was the chief executive of AkzoNobel during the period in which Elliot was invested in the firm and worked with Markel there, will also join Finch Bay Capital as a senior adviser and investor.
