In the past few days:
Mullen Trucking: MTL - originally an oil services trucking company. They have diversified into trucking across Canada, which will do well in the cheap fuel environment. I held this in 2005 to 2008. FFH bought private notes from Mullen in 2009 to help Mullen survive the crunch and of course make money for Fairfax. Really well run and easy to understand.
ARX - Arc Resources - Smallish position. I held this in 2005-2008 time as well. Very well run, large E&P company. Well hedged into this downturn.
Russell Metals - RUS - huge metal distributor. Trading down due to part of its business being related to the oil industry. One concern: Dividend payout is close to 100% but they can probably handle it. It is basically an inventory turn company. Non-oil business may accelerate in the US and Canada.
FN - Canadian mortgage company - 70% privately held. This is my mortgage company, and the largest non- bank mortgage lender in Canada. I am still working on understanding it fully. It is basically a mortgage securitization company. I am trying to determine their liability to the mortgages they have securitized. They dont do commercial real estate at all.
I will add that I am not commenting further on any of these for now. If you are interested, read the financials and come to your own conclusions. I dont want to influence anyone with my viewpoints.
