[1] | Net of profit commission, which is impacted by the level of ceded losses recoverable, if any, on reinsurance transactions. See Note 10 for additional information on our reserve for losses and reinsurance recoverables.
[2] | Effective December 31, 2017, we amended the 2016 Single Premium QSR Agreement to increase the amount of ceded risk on performing loans under the agreement from 35% to 65% for the 2015 through 2017 vintages. Loans included in the 2012 through 2014 vintages, and any other loans subject to the agreement that were delinquent at the time of the amendment, were unaffected by the change and therefore the amount of ceded risk for those loans continues to range from 20% to 35%.
