Financing Receivable Allowance For Credit Loss Additional Information [Abstract] |  |
Average Historical Chargeback Term | 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. |
