Uncollected Payments | [1] | 0.80% | 0.80%
Discount rate | [1] | 9.10% | 9.60%
[1] | Weighted averages for unobservable inputs are calculated based on the unpaid principal balance of the portfolios.
[2] | Significant increases (decreases) in any of the inputs in isolation may result in significantly lower (higher) fair value measurements. A change in the assumption used for discount rates may be accompanied by a directionally similar change in the assumption used for the probability of uncollected payments and a directionally opposite change in the assumption used for prepayment rates.
