[1] A break in yield for a given tranche investment means that defaults and/or deferrals have reached such a level that the specific tranche would not receive all of the contractual principal and interest cash flow by its maturity, resulting in not a temporary shortfall, but an actual loss. This column represents the percentage of additional defaults among the currently performing and deferred collateral that would result in OTTI loss.
