MER had gross sub-prime CDO exposure of $30.4 billion, 3.3x the group average. MER also had the worst liquidity ratio at 52%." MER April option implied volatility of 107 is above its 26-week average of 45 according to Track Data, suggesting larger risk. MER implied volatility is near a level attained in October of 1987.
