(1)The average FICO scores at December 31, 2021 are based upon rescores from December 2021, as available for previously originated loans, or origination score data for loans booked in December 2021. The average FICO scores at December 31, 2020 were based upon rescores from December 2020, as available for previously originated loans, or origination score data for loans booked in December 2020. (2)The combined LTV ratios for December 31, 2021 are based upon updated automated valuations as of November 2021, when available, and/or the most current valuation data available. The combined LTV ratios for December 31, 2020 were based upon updated automated valuations as of November 2020, when available, and/or the most current valuation data available as of such date. The updated automated valuations provide new information on loans that may be available since the previous valuation was obtained. If no new information is available, the valuation will default to the previously obtained data or most recent appraisal. (3)For home equity loans and lines in a subordinate lien, the LTV data represents a combined LTV, taking into account the senior lien data for loans and lines. |
