Summary of Changes to MSR Assets | The following table summarizes changes to the MSR assets:
| Three Months Ended March 31, |  |
| 2023 |  | 2022 |  |  |  |
Fair value, beginning of period | $ | 6,946,940 |  |  | $ | 5,385,613 |  |  |  |  |
MSRs originated | 204,560 |  |  | 796,616 |  |  |  |  |
MSRs sales | (81,538) |  |  | (253,997) |  |  |  |  |
Changes in fair value: |  |  |  |  |  |  |
Due to changes in valuation model inputs or assumptions (1) | (217,802) |  |  | 767,271 |  |  |  |  |
Due to collection/realization of cash flows | (182,221) |  |  | (285,215) |  |  |  |  |
Total changes in fair value | (400,023) |  |  | 482,056 |  |  |  |  |
Fair value, end of period | $ | 6,669,939 |  |  | $ | 6,410,288 |  |  |  |  |
(1) Reflects changes in assumptions including discount rates and prepayment speed assumptions, mostly due to changes in market interest rates. Does not include the change in fair value of derivatives that economically hedge MSRs identified for sale or the effects of contractual prepayment protection resulting from sales of MSRs.
Schedule of Assumptions Used to Determine Fair Value of MSRs | The following is a summary of the weighted average discount rate and prepayment speed assumptions used to determine the fair value of MSRs as well as the expected life of the loans in the servicing portfolio:
| March 31, 2023 |  | December 31, 2022
Discount rate | 9.9 | % |  | 9.9 | %
Prepayment speeds | 7.1 | % |  | 6.9 | %
Life (in years) | 7.97 |  | 8.08
Summary of Discount Rate and Prepayment Speeds at Two Different Data Points | The following table stresses the discount rate and prepayment speeds at two different data points:
| Discount Rate |  | Prepayment Speeds
| 100 BPS Adverse Change |  | 200 BPS Adverse Change |  | 10% Adverse Change |  | 20% Adverse Change

X
- Definition Tabular disclosure of a sensitivity analysis or stress test showing the hypothetical effect on the fair value of the transferor's interests in transferred financial assets (including any servicing assets or servicing liabilities) of two or more unfavorable variations from the expected levels for each key assumption that is reported, independently determined from any change in another key assumption, and a description of the objectives, methodology, and limitations of the sensitivity analysis or stress test. + References Reference 1: http://www.xbrl.org/2009/role/commonPracticeRef -Publisher FASB -Name Accounting Standards Codification -Topic 860 -SubTopic 20 -Section 50 -Paragraph 4 -Subparagraph (c) -URI https://asc.fasb.org/extlink&oid=121570589&loc=d3e107314-111719 + Details
