You do realize that Berkshire will also take a hit due to losses in New Zealand. Are you shorting MRH?
The big difference between MRH and BRK is that we're able to buy back shares and they're accretive to earnings because we only pay 80% or less of book. And it looks like Mr. Market is going to tumble due to unrest here with State workers demonstrating and overseas with unrest in the Middle East.
Most of MRH's assets are tied up in 3-4 year bonds.
