Why would they be investing in Greece? The government corruption there is well known. They should have spread the risk around solid countries, i.e. Germany, France, Finland, Canada, US(maybe). Greece come on!!
Not being privy to when these toxic assets were purchased, I suspicion that they were purchased prior to the economic melt down of most world economies. Most importantly these assets were probably viable at time of purchase, but, subject now to current economic conditions making them toxic. One must question whether or not these assets were good investments to own in the first place. Still you must give some credit to the decision to liquidate them with the current loss rather than to hold wishing and hoping for a world economic turn around. Every investor has a stop loss in place. Was AFLAC's stop loss too loose?
