Key Economic Assumptions Used in Measuring Initial FV of Capitalized Single Family MSRs | Key economic assumptions used in measuring the initial fair value of capitalized single family MSRs were as follows for the periods indicated:
| Quarter Ended June 30, |  | Six Months Ended June 30,
(rates per annum) (1) | 2021 |  | 2020 |  | 2021 |  | 2020
Constant prepayment rate ("CPR") (2) | 8.33 | % |  | 12.64 | % |  | 8.35 | % |  | 13.76 | %
Discount rate | 8.48 | % |  | 7.88 | % |  | 8.43 | % |  | 7.86 | %
(1) Based on a weighted average. (2) Represents an expected lifetime average CPR used in the model.
Schedule of Sensitivity Analysis of Fair Value, Transferor's Interests in Transferred Financial Assets | For single family MSRs, we use a discounted cash flow valuation technique which utilizes CPRs and discount rates as significant unobservable inputs as noted in the table below:
| At June 30, 2021 |  | At December 31, 2020
| Range of Inputs |  | Average (1) |  | Range of Inputs |  | Average (1)
CPRs | 8.80% - 17.73% |  | 11.04 | % |  | 8.13% - 19.70% |  | 12.81 | %
Discount Rates | 6.47% - 13.67% |  | 7.78 | % |  | 6.50% - 13.14% |  | 8.27 | %
(1) Averages of all the inputs within the range. To compute hypothetical sensitivities of the value of our single family MSRs to immediate adverse changes in key assumptions, we computed the impact of changes to CPRs and in discount rates as outlined below:
(dollars in thousands) | At June 30, 2021
Fair value of single family MSR | $ | 59,872 |
Expected weighted-average life (in years) | 5.64
CPR |
Impact on fair value of 25 basis points adverse change in interest rates | $ | (3,366) |
Impact on fair value of 50 basis points adverse change in interest rates | $ | (6,677) |
Discount rate |
Impact on fair value of 100 basis points increase | $ | (2,803) |
Impact on fair value of 200 basis points increase | $ | (5,394) |
Changes in Multifamily MSRs Measured at the Lower of Amortized Cost or Fair Value | The changes in multifamily and SBA MSRs measured at the lower of amortized cost or fair value were as follows for the periods indicated:
| Quarter Ended June 30, |  | Six Months Ended June 30,
(in thousands) | 2021 |  | 2020 |  | 2021 |  | 2020

Amortization | (2,133) |  |  | (1,185) |  |  | (3,477) |  |  | (2,516) |
Ending balance | $ | 39,113 |  |  | $ | 30,583 |  |  | $ | 39,113 |  |  | $ | 30,583 |
