Are these actually rated by an agency? I haven't been following TABX closely recently, but I don't remember seeing any official ratings on the tranches. As far as the wide spreads go - I wouldn't call it surprising given the way the subprime debacle. The underlying ABX indices reference thin BBB and BBB- on highly correlated collateral, if anything senior TABX tranches seem tight.
