Fair Value Measurement Inputs and Valuation Techniques | The table below presents information about the significant unobservable inputs used for recurring fair value measurements for certain Level 3 instruments, and includes only those instruments for which information about the inputs is reasonably available to us, such as data from independent third-party valuation service providers. Because input information from third-parties with respect to certain Level 3 instruments (primarily CLO/ABS) may not be reasonably available to us, balances shown below may not equal total amounts reported for such Level 3 assets and liabilities:
(in millions) |  | Fair Value at December 31, 2024 | Valuation Technique | Unobservable Input(b) | Range (Weighted Average)(c)

(a)Information received from third-party valuation service providers. The ranges of the unobservable inputs for constant prepayment rate, loss severity and constant default rate relate to each of the individual underlying mortgage loans that comprise the entire portfolio of securities in the RMBS and CLO securitization vehicles and not necessarily to the securitization vehicle bonds (tranches) purchased by us. The ranges of these inputs do not directly correlate to changes in the fair values of the tranches purchased by us, because there are other factors relevant to the fair values of specific tranches owned by us including, but not limited to, purchase price, position in the waterfall, senior versus subordinated position and attachment points. (b)Represents discount rates, estimates and assumptions that we believe would be used by market participants when valuing these assets and liabilities. (c)The weighted averaging for fixed maturity securities is based on the estimated fair value of the securities.
