Accounting for writedowns that are possible for PRE in the CGX investment.If PRE's auditors look at their investment in CGX, as some point they will ask what is the likely possibility that their investment will come back to level IE 2.90 per share or .29 cents before the split. They could say very likely and put it off for the time being .Accounting rules now want shareholders to have a relatively real value picture of assets within companies. If PRE deside to take the write off, it will come directly off the earnings and affect the Price Earnings ratio that the company trades at. In PRE's case, it may not be drastic, but I doubt they want to do so. Right now, CGX is on the balance sheet as an asset at book value, obviously, it is somewhat below Book value at the current price. Hope that helps. I'm betting they won't need to take a write down but , as you know, I've been wrong all along with CGX.
