We have not yet ceded reserves under any of the ILN Transactions or XOL Transactions as incurred claims and claim expenses on each respective reference pool remain within our retained coverage layer for each transaction. Our reserve setting process considers the beneficial impact of forbearance, foreclosure moratorium and other assistance programs that may be made available to certain defaulted borrowers.

The risk-based required asset amount is a function of the risk profile of an approved insurer's RIF, assessed on a loan-by-loan basis and considered against certain risk-based factors derived from tables set out in the PMIERs, which is then adjusted on an aggregate basis for reinsurance transactions approved by the GSEs, such as with respect to our ILN Transactions, XOL Transactions and QSR Transactions.

Claims incurred are generally affected by a variety of factors, including: • future macroeconomic factors, including national and regional unemployment rates, which affect the likelihood that borrowers may default on their loans and probability of claims, and interest rates, which tend to drive increased persistency as they rise, thereby extending the average life of our insured portfolio and increasing expected future claims and decrease persistency as they fall, thereby shortening the average life of our insured portfolio and moderating future expected claims; • changes in housing values, as such changes affect loss mitigation opportunities (available to us and a borrower) on loans in default, as well as borrowers' behaviors and willingness to default if the values of their homes are below or perceived to be below the balance of their mortgage; • borrowers' FICO scores, with lower FICO scores tending to have a higher probability of claims; • borrowers' DTI ratios, with higher DTI ratios tending to have a higher probability of claims; • LTV ratios, with higher average LTV ratios tending to increase the probability of claims; • the size of loans insured, with higher loan amounts tending to result in higher incurred claim amounts than smaller loan amounts; • the percentage of coverage on insured loans, with higher percentages of insurance coverage tending to result in higher incurred claim amounts than lower percentages of insurance coverage; • other borrower, property-type and loan level risk characteristics, such as cash-out refinancings, second homes or investment properties; and • the level and amount of reinsurance coverage maintained with third parties.

We believe the introduction and utilization of Rate GPS ® provides us with a more granular and analytical approach to evaluating and pricing risk, and that this approach enhances our ability to continue building a high-quality mortgage insurance portfolio and delivering attractive risk-adjusted returns. Premiums are generally fixed for the duration of our coverage of the underlying loans.
