(in thousands) | At September 30, 2021 |  | At December 31, 2020
Single family | $ | 5,625,386 |  |  | $ | 5,914,592 |

The Company has made representations and warranties that the loans sold meet certain requirements. The Company may be required to repurchase mortgage loans or indemnify loan purchasers due to defects in the origination process of the loan, such as documentation errors, underwriting errors and judgments, appraisal errors, early payment defaults and fraud. The following is a summary of changes in the Company's liability for estimated single-family mortgage repurchase losses for the periods indicated:
| Quarter Ended September 30, |  | Nine Months Ended September 30,
(in thousands) | 2021 |  | 2020 |  | 2021 |  | 2020
Balance, beginning of period | $ | 1,612 |  |  | $ | 2,083 |  |  | $ | 2,122 |  |  | $ | 2,871 |
Additions, net of adjustments (1) | (183) |  |  | 252 |  |  | (229) |  |  | (275) |
Realized (losses) recoveries, net (2) | 14 |  |  | (240) |  |  | (450) |  |  | (501) |
Balance, end of period | $ | 1,443 |  |  | $ | 2,095 |  |  | $ | 1,443 |  |  | $ | 2,095 |
(1) Includes additions for new loan sales and changes in estimated probable future repurchase losses on previously sold loans. (2) Includes principal losses and accrued interest on repurchased loans, "make-whole" settlements, settlements with claimants and certain related expenses. The Company has agreements with certain investors to advance scheduled principal and interest amounts on delinquent loans. Advances are also made to fund the foreclosure and collection costs of delinquent loans prior to the recovery of reimbursable amounts from investors or borrowers. Advances of $2.5 million and $3.0 million were recorded in other assets as of September 30, 2021 and December 31, 2020, respectively. When the Company has the unilateral right to repurchase Ginnie Mae pool loans it has previously sold (generally loans that are more than 90 days past due), the Company records the balance of the loans as other assets and other liabilities. At September 30, 2021 and December 31, 2020, delinquent or defaulted mortgage loans currently in Ginnie Mae pools that the Company has recognized on its consolidated balance sheets totaled $32 million and $102 million, respectively. Revenue from mortgage servicing, including the effects of derivative risk management instruments, consisted of the following for the periods indicated:

(1) Represents changes due to collection/realization of expected cash flows and curtailments. (2) Principally reflects changes in model assumptions, including prepayment speed assumptions, which are primarily reflected by changes in mortgage interest rates. The changes in single family MSRs measured at fair value are as follows for the periods indicated:
| Quarter Ended September 30, |  | Nine Months Ended September 30,
(in thousands) | 2021 |  | 2020 |  | 2021 |  | 2020

(1) Represents changes due to collection/realization of expected cash flows and curtailments. (2) Principally reflects changes in model assumptions, including prepayment speed assumptions, which are primarily reflected by changes in mortgage interest rates. Key economic assumptions used in measuring the initial fair value of capitalized single family MSRs were as follows for the periods indicated:
| Quarter Ended September 30, |  | Nine Months Ended September 30,
(rates per annum) (1) | 2021 |  | 2020 |  | 2021 |  | 2020
Constant prepayment rate ("CPR") (2) | 9.84 | % |  | 20.0% - 30.0% |  | 8.75 | % |  | 17.1% - 30.0%
Discount rate | 7.77 | % |  | 7.71 | % |  | 8.25 | % |  | 7.78 | %
(1) Based on a weighted average. (2) Represents an expected lifetime average CPR used in the model. 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 September 30, 2021 |  | At December 31, 2020
| Range of Inputs |  | Average (1) |  | Range of Inputs |  | Average (1)
CPRs | 7.98% - 17.43% |  | 10.74 | % |  | 8.13% - 19.70% |  | 12.81 | %
Discount Rates | 6.54% - 13.78% |  | 7.84 | % |  | 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 September 30, 2021
Fair value of single family MSR | $ | 61,206 |
Expected weighted-average life (in years) | 5.87
CPR |
Impact on fair value of 25 basis points adverse change in interest rates | $ | (3,490) |
Impact on fair value of 50 basis points adverse change in interest rates | $ | (7,016) |
Discount rate |
Impact on fair value of 100 basis points increase | $ | (2,949) |
Impact on fair value of 200 basis points increase | $ | (5,675) |
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 September 30, |  | Nine Months Ended September 30,
(in thousands) | 2021 |  | 2020 |  | 2021 |  | 2020
Beginning balance | $ | 39,113 |  |  | $ | 30,583 |  |  | $ | 35,774 |  |  | $ | 29,494 |
Originations | 2,270 |  |  | 2,524 |  |  | 9,086 |  |  | 6,129 |
Amortization | (1,758) |  |  | (1,301) |  |  | (5,235) |  |  | (3,817) |
Ending balance | $ | 39,625 |  |  | $ | 31,806 |  |  | $ | 39,625 |  |  | $ | 31,806 |
