Financing Receivable Additional Disclosures [Abstract] |
Modeling of mortgage loans | Modeling for the company's mortgage loans is based on inputs most highly correlated to defaults, including loan-to-value, occupancy, and payment history. Historical credit loss experience provides additional support for the estimation of expected credit losses. In assessing the credit losses, the portfolio is reviewed on a collective basis, using loan-specific cash flows to determine the fair value of the collateral in the event of default. Adjustments to this analysis are made to assess loans with a loan-to-value of 65% or greater. These loan are evaluated on an individual basis and loan specific risk characteristics such as occupancy levels, expense, income growth and other relevant available information from internal and external sources relating to past events, current conditions, and reasonable and supportable forecasts.
