New insurance written adds insured principal to the portfolio, while cancellations and principal payments reduce the existing book. FICO, LTV, DTI, and purchase mix describe important underwriting characteristics of new business, and the resulting flows determine insurance in force and risk in force without making principal balance equivalent to insured loss exposure.

About this market data
IEX historical data reflects IEX activity only and is presented as a source-scoped reference point, not as consolidated U.S. market history.
Screened reference metrics use K9-qualified IEX reference history and only explicitly registered positive split events. They do not assert complete split history, consolidated U.S. market performance, or canonical adjusted prices.
Data provided for free by IEX. By accessing or using IEX Historical Data, you agree to the IEX Historical Data Terms of Use.
The raw chart can show a discontinuity around a stock split because it is intentionally unadjusted. The screened metrics use only explicitly registered positive split events and do not assert complete split history.
