[1] | Related to ceded losses on captive reinsurance transactions and the QSR Transactions. See Note 7 for additional information.
[2] | Amounts previously reported for losses and LAE incurred in respect of default notices reported and unreported in current year and prior years have been reclassified to correct an error. There was no net change to total incurred losses in any period as a result of these reclassifications. For the three and nine months ended September 30, 2014, the amounts previously reported for losses and LAE incurred in respect of default notices reported and unreported in current year have been revised downward by approximately $34.5 million and $82.8 million, respectively, with an equal and offsetting adjustment to the amount previously reported for default notices reported and unreported in prior years. For the years ended December 31, 2014, 2013 and 2012, the amounts previously reported related to losses and LAE incurred from current year default notices should have been lower by approximately $71.8 million, $65.0 million and $75.7 million, respectively, with equal and offsetting adjustments to the incurred loss amounts related to prior years’ default notices.
[3] | Related to underlying defaulted loans with a most recent default notice dated in the year indicated. For example, if a loan had defaulted in a prior year, but then subsequently cured and later re-defaulted in the current year, that default would be considered a current year default.
[4] | Primarily represents ceded losses on captive transactions and the QSR Transactions.
