_________ (a)Transfers into Level 3 are the result of unobservable inputs utilized within valuation methodologies for assets that were previously valued using observable inputs. Transfers out of Level 3 are due to the use of observable inputs in valuation methodologies as well as the utilization of independent pricing service information for certain assets that the Company is able to validate. (b)Purchases, sales, issuances and settlements represent the activity that occurred during the period that results in a change of the asset but does not represent changes in fair value for the instruments held at the beginning of the period. Such activity primarily consists of purchases and sales of fixed maturity and equity securities. There were no issuances or settlements during the three months ended June 30, 2025.

Schedule of Fair Value Measurement Inputs | The following table provides additional information about the significant unobservable (Level 3) inputs developed internally by the Company to determine fair value for certain assets and liabilities carried at fair value at June 30, 2025 (dollars in millions):
| Fair value at June 30, 2025 |  | Valuation techniques |  | Unobservable inputs |  | Range (weighted average) (a)
Assets: |  |  |  |  |  |  |
Asset-backed securities (b) | $ | 7.7 |  |  | Discounted cash flow analysis |  | Discount margins |  | 2.26%
Asset-backed securities (c) | 3.5 |  |  | Recovery method |  | % Recovery expected |  | 62.00%
Equity securities (d) | 64.7 |  |  | Market comparables |  | EBITDA multiples |  | 11.4X
Total | 75.9 |  |  |  |  |  |  |
Liabilities: |  |  |  |  |  |  |
Market risk benefit liability (e) | 63.8 |  |  | Discounted cash flow analysis |  | Surrender rates |  | 1.45% - 17.00% (4.38%)
|  |  |  |  | Utilization rates |  | 5.92% - 47.62% (24.95%)
Embedded derivatives related to fixed indexed annuity products (f) | 1,502.4 |  |  | Discounted projected embedded derivatives |  | Projected portfolio yields |  | 4.52% - 4.92% (4.69%)
|  |  |  |  | Discount rates |  | 3.64% - 6.96% (4.87%)
|  |  |  |  | Surrender rates |  | 1.45% - 30.10% (7.54%)
________________________________ (a) The weighted average is based on the relative fair value of the related assets or liabilities. (b) Asset-backed securities - The significant unobservable input used in the fair value measurement of these asset-backed securities is discount margin added to a riskless market yield. Significant increases (decreases) in discount margin in isolation would have resulted in a significantly lower (higher) fair value measurement. (c) Asset-backed securities - The significant unobservable input used in the fair value measurement of these corporate securities is percentage of recovery expected. Significant increases (decreases) in percentage of recovery expected in isolation would have resulted in a significantly higher (lower) fair value measurement. (d) Equity securities - The significant unobservable input used in the fair value measurement of these equity securities is multiples of earnings before interest, taxes, depreciation and amortization ("EBITDA"). Generally, increases (decreases) in the EBITDA multiples would result in higher (lower) fair value measurements. (e) Market risk benefits – Many of our fixed indexed annuity products include a guaranteed living withdrawal benefit ("GLWB") that is considered a MRB. The calculation of the value of MRBs is based on significant unobservable inputs including nonmarket assumptions related to mortality rates, surrender and withdrawal rates and GLWB utilization. These assumptions are based on actuarial estimates and past experience. Increases in assumed surrender rates would generally increase the value of a MRB asset or decrease the value of a MRB liability (with decreases in assumed surrender rates having the opposite impacts). Increases in utilization rates would generally decrease the value of a MRB asset or increase the value of a MRB liability (with decreases in utilization rates having the opposite impacts). (f) Embedded derivatives related to fixed indexed annuity products are classified as policyholder account liabilities on the consolidated balance sheet. The significant unobservable inputs used in the fair value measurement of our embedded derivatives associated with fixed indexed annuity products are projected portfolio yields, discount rates and surrender rates. Increases (decreases) in projected portfolio yields in isolation would have resulted in a higher (lower) fair value measurement. The discount rate is based on risk free rates (U.S. Treasury rates for similar durations) adjusted for our non-performance risk and risk margins for non-capital market inputs. Increases (decreases) in the discount rates would have resulted in a lower (higher) fair value measurement. Assumed surrender rates are used to project how long the contracts remain in force. Generally, the longer the contracts are assumed to be in force the higher the fair value of the embedded derivative. The following table provides additional information about the significant unobservable (Level 3) inputs developed internally by the Company to determine fair value for certain assets and liabilities carried at fair value at December 31, 2024 (dollars in millions):
| Fair value at December 31, 2024 |  | Valuation techniques |  | Unobservable inputs |  | Range (weighted average) (a)

Significant increases (decreases) in discount margin in isolation would have resulted in a significantly lower (higher) fair value measurement. (c) Asset-backed securities - The significant unobservable input used in the fair value measurement of these corporate securities is percentage of recovery expected. Significant increases (decreases) in percentage of recovery expected in isolation would have resulted in a significantly higher (lower) fair value measurement. (d) Equity securities - The significant unobservable input used in the fair value measurement of these equity securities is multiples of EBITDA. Generally, increases (decreases) in the EBITDA multiples would result in higher (lower) fair value measurements. (e) Market risk benefits – Many of our fixed indexed annuity products include a GLWB that is considered a MRB. The calculation of the value of MRBs is based on significant unobservable inputs including nonmarket assumptions related to mortality rates, surrender and withdrawal rates and GLWB utilization. These assumptions are based on actuarial estimates and past experience. Increases in assumed surrender rates would generally increase the value of a MRB asset or decrease the value of a MRB liability (with decreases in assumed surrender rates having the opposite impacts). Increases in utilization rates would generally decrease the value of a MRB asset or increase the value of a MRB liability (with decreases in utilization rates having the opposite impacts). (f) Embedded derivatives related to fixed indexed annuity products are classified as policyholder account liabilities on the consolidated balance sheet. The significant unobservable inputs used in the fair value measurement of our embedded derivatives associated with fixed indexed annuity products are projected portfolio yields, discount rates and surrender rates. Increases (decreases) in projected portfolio yields in isolation would have resulted in a higher (lower) fair value measurement. The discount rate is based on risk free rates (U.S. Treasury rates for similar durations) adjusted for our non-performance risk and risk margins for non-capital market inputs. Increases (decreases) in the discount rates would have resulted in a lower (higher) fair value measurement. Assumed surrender rates are used to project how long the contracts remain in force. Generally, the longer the contracts are assumed to be in force the higher the fair value of the embedded derivative. The fair value of our financial instruments not carried at fair value on a recurring basis are as follows (dollars in millions):
