Markel will merge Alterra’s operations with its own following the deal, with each Alterra common share being converted into the right to receive about 0.04 Markel common shares, plus a cash payment of $10.
Following the merger Markel’s existing shareholders will own about 69 per cent of the combined entity once the deal is completed, which is expected to happen in the first half of 2013.

Stone Point has raised about $9bn across five Trident funds since 1994, with its most recent closing on $3.5bn in 2010.
The firm focuses on deals in the financial services sector.
