Fair Value Disclosures [Abstract]  
Fair Value of Financial Instruments Fair Value of Financial Instruments
For financial reporting purposes, we follow a fair value hierarchy established under GAAP that is used to determine the fair value of financial instruments. This hierarchy prioritizes relevant market inputs in order to determine an “exit price” at the measurement date, or the price at which an asset could be sold or a liability could be transferred in an orderly process that is not a forced liquidation or distressed sale. Level 1 inputs are observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2 inputs are observable inputs other than quoted prices for an asset or liability that are obtained through corroboration with observable market data. Level 3 inputs are unobservable inputs (e.g., our own data or assumptions) that are used when there is little, if any, relevant market activity for the asset or liability required to be measured at fair value.
In certain cases, inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, the level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. Our assessment of the significance of a particular input requires judgment and considers factors specific to the asset or liability being measured.
The following table presents the carrying values and estimated fair values of assets and liabilities that are required to be recorded or disclosed at fair value at December 31, 2023 and 2022.

Valuation Policy
We maintain policies that specify the methodologies we use to value different types of financial instruments. Significant changes to the valuation methodologies are reviewed by members of the Pricing Committee, which is comprised of several members of senior management, to confirm the changes are appropriate and reasonable. Valuations based on information from external sources are generally performed on an instrument-by-instrument basis with the resulting amounts analyzed individually against internal calculations as well as in the aggregate by product type classification. Initial valuations are performed by our Portfolio Management Groups using the valuation processes described below. Our Pricing Committee then independently reviews all fair value estimates to ensure they are reasonable.
Valuation Process
We estimate fair values for financial assets or liabilities based on available inputs observed in the marketplace as well as unobservable inputs. We primarily use two pricing valuation techniques: market comparable pricing and discounted cash flow analysis. Market comparable pricing is used to determine the estimated fair value of certain instruments by incorporating known inputs and performance metrics, such as observed prepayment rates, delinquencies, severities, credit support, recent transaction prices, pending transactions, or prices of other similar instruments. Discounted cash flow analysis techniques generally consist of developing an estimate of future cash flows that are expected to occur over the life of an instrument and then discounting those cash flows at a rate of return that results in an estimate of fair value. After considering all available indications of the appropriate rate of return that market participants would require, we consider the reasonableness of the range indicated by the results to determine an estimate that is most representative of fair value. We also consider counterparty credit quality and risk as part of our fair value assessments.
The following table provides quantitative information about the significant unobservable inputs used in the valuation of our Level 3 assets and liabilities measured at fair value.

Footnotes to Table 5.7
(1)The weighted average input values for all loan types are based on unpaid principal balance. The weighted average input values for all other assets and liabilities are based on relative fair value.
(2)Values represent pricing inputs used in securitization pricing model. Credit spreads represent spreads to applicable swap rates unless specified otherwise.
(3)The fair value of the loans and HEI held by consolidated entities is based on the fair value of the ABS issued by these entities and the securities and other investments we own in those entities, which we determined were more readily observable in accordance with accounting guidance for collateralized financing entities. At December 31, 2023, the fair value of securities we owned at the consolidated Sequoia, CAFL Term, CAFL Bridge (under CFE), Freddie Mac SLST, Freddie Mac K-Series, and HEI securitization entities was $212 million, $323 million, $22 million, $274 million, $33 million, and $34 million, respectively. CAFL Bridge only includes the one securitization that we made the CFE election for.
(4)Represents the estimated average duration of outstanding servicer advances at a given point in time (not taking into account new advances made with respect to the pool).
(5)Fair value presented in this line item for ABS issued at consolidated HEI entities does not include non-controlling interests in our HEI entities, which we account for separately as liabilities in our Consolidated Balance Sheets and carry at fair value. However, given the HEI non-controlling interests are priced using the same model and inputs, the unobservable inputs and input values provided in this section include those for the HEI non-controlling interests.
Determination of Fair Value
A description of the instruments measured at fair value as well as the general classification of such instruments pursuant to the Level 1, Level 2, and Level 3 valuation hierarchy is listed herein. We generally use both market comparable information and discounted cash flow modeling techniques to determine the fair value of our Level 3 assets and liabilities. Use of these techniques requires the determination of relevant inputs and assumptions, some of which represent significant unobservable inputs as indicated in the preceding table. Accordingly, a significant increase or decrease in any of these inputs – such as anticipated credit losses, prepayment rates, interest rates, or other valuation assumptions – in isolation would likely result in a significantly lower or higher fair value measurement.
Residential loans, business purpose loans, multifamily loans and HEI at consolidated entities
We have elected to account for most of our consolidated securitization entities as collateralized financing entities in accordance with GAAP. A CFE is a variable interest entity that holds financial assets and issues beneficial interests in those assets, and these beneficial interests have contractual recourse only to the related assets of the CFE. Accounting guidance for CFEs allows companies to elect to measure both the financial assets and financial liabilities of a CFE using the more observable of the fair value of the financial assets or fair value of the financial liabilities. Pursuant to this guidance, we use the fair value of the ABS issued by the CFEs (which we determined to be more observable) to determine the fair value of the loans or HEI held at these entities, whereby the net assets we consolidate in our financial statements related to these entities represent the estimated fair value of our retained interests in the CFEs. 
Residential loans at Redwood
Estimated fair values for residential loans are determined using models that incorporate various pricing inputs, including information derived from whole loan sales and securitizations that have occurred in the market. Certain significant inputs in these models are considered unobservable and are therefore Level 3 in nature. Significant pricing inputs obtained from market whole loan transaction activity include indicative spreads to indexed TBA prices and indexed swap rates (Level 3). Significant pricing inputs obtained from market securitization activity include indicative spreads to indexed TBA prices and swap rates for senior and subordinate MBS, IO MBS discount rates, senior credit support levels, and assumed future prepayment rates (Level 3). These assets would generally decrease in value based upon an increase in the credit spread, prepayment speed, or credit support assumptions.
Business purpose loans
Estimated fair values for business purpose loans are determined using models that incorporate various pricing inputs, including information derived from whole loan sales and securitizations that have occurred in the market. Certain significant inputs in these models are considered unobservable and are therefore Level 3 in nature. Significant pricing inputs obtained from market securitization activity include indicative spreads to indexed treasury rates for senior and subordinate MBS, IO MBS discount rates, senior credit support levels, and assumed future prepayment rates (Level 3). Significant pricing inputs obtained from market whole loan transaction
activity include indicative credit spreads to indexed treasury prices and swap rates or absolute yields (Level 3). These assets would generally decrease in value based upon an increase in the credit spread or absolute yield, prepayment speed, or credit support assumptions. Prices for most of our BPL bridge loans are determined using discounted cash flow modeling, which incorporates a primary significant unobservable input of market discount rates (incorporating indicative credit spreads where applicable). Cash flows for performing loans are generally based on contractual loan terms. Delinquent loans are generally valued at a dollar price that is informed by various market data inputs, including the estimated fair value of the collateral securing the loan (Level 3). These assets would generally decrease in value based upon an increase in the discount rate or a decrease in the value of the underlying collateral.
Real estate securities
Real estate securities include residential, multifamily, and other mortgage-backed securities that are generally illiquid in nature and trade infrequently. Significant inputs in the valuation analysis for these assets are predominantly Level 3 in nature, due to the lack of readily available market quotes and related inputs. For real estate securities, we utilize both market comparable pricing and discounted cash flow analysis valuation techniques. Relevant market indicators that are factored into the analysis include bid/ask spreads, the amount and timing of credit losses, interest rates, and collateral prepayment rates (Level 3). Securities priced using discounted cash flow models use significant unobservable inputs such as a discount rate, prepayment rate, default rate and loss severity. The estimated fair value of our securities would generally decrease based upon an increase in discount rate, default rates, loss severities, or a decrease in prepayment rates.
Derivative assets and liabilities
Our derivative instruments include swaps, swaptions, TBAs, interest rate futures, loan purchase commitments, and forward sale commitments. Fair values of derivative instruments are determined using quoted prices from active markets, when available, or from valuation models and are supported by valuations provided by dealers active in derivative markets. Fair values of TBAs and interest rate futures are generally obtained using quoted prices from active markets (Level 1). Our derivative valuation models for swaps and swaptions require a variety of inputs, including contractual terms, market prices, yield curves, credit curves, measures of volatility, prepayment rates, and correlations of certain inputs. Model inputs can generally be verified and model selection does not involve significant management judgment (Level 2). LPC, and IRLC fair values for residential jumbo and BPL term loans are estimated based on the estimated fair values of the underlying loans (as described in "Residential loans at Redwood" and "Business purpose loans" above). In addition, fair values for LPCs and IRLCs are estimated based on the probability that the mortgage loan will be purchased or originated (the "Pull-through rate") (Level 3). A decrease in pull-through rate would decrease the value of LPCs with a positive fair value.
Servicer advance investments
Estimated fair values for servicer advance investments are determined through internal pricing models that estimate future cash flows and utilize certain significant inputs that are considered unobservable and are therefore Level 3 in nature. Our estimations of cash flows include the combined cash flows of all of the components that comprise the servicer advance investments: existing advances, the requirement to purchase future advances, the recovery of advances, and the right to a portion of the associated mortgage servicing fee ("mortgage servicing income"). The valuation technique is based on discounted cash flows. Significant inputs used in the valuations include prepayment rate (of the loans underlying the investments), mortgage servicing income, the weighted-average expected remaining life of servicer advances ("expected remaining life"), and discount rate. These assets would generally decrease in value based upon an increase in prepayment rates, an increase in expected remaining life, an increase in discount rate, or a decrease in mortgage servicing income.
HEI at Redwood
Estimated fair values for home equity investment contracts are determined through internal pricing models that estimate future cash flows and utilize certain significant unobservable inputs such as forecasted home price appreciation, prepayment rates and discount rates, and are therefore Level 3 in nature. The valuation technique is based on discounted cash flows. An increase in discount rate or a decrease in forecasted home price appreciation combined with a decrease in prepayment rates, would generally reduce the estimated fair value of the HEI.
MSRs
MSRs include the rights to service jumbo residential mortgage loans. Significant inputs in the valuation analysis are predominantly Level 3, due to the nature of these instruments and the lack of readily available market quotes. Changes in the fair value of MSRs occur primarily due to the collection/realization of expected cash flows, as well as changes in valuation inputs and assumptions. Estimated fair values are based on applying the inputs to generate the net present value of estimated future MSR income (Level 3). These discounted cash flow models utilize certain significant unobservable inputs including market discount rates, assumed future prepayment rates of serviced loans, and the market cost of servicing. An increase in these unobservable inputs would generally reduce the estimated fair value of the MSRs.
Excess MSRs
Estimated fair values for excess MSRs are determined through internal pricing models that estimate future cash flows and utilize certain significant inputs that are considered unobservable and are therefore Level 3 in nature. The valuation technique is based on discounted cash flows. Significant unobservable inputs used in the valuations include prepayment rate (of the loans underlying the investments), the amount of excess servicing income expected to be received ("excess mortgage servicing income"), and discount rate. These assets would generally decrease in value based upon an increase in prepayment rates or discount rate, or a decrease in excess mortgage servicing income.
Other Investments
Certain of our Other investments (inclusive of strategic investments in early-stage start-up companies) are Level 3 financial instruments that we account for under the fair value option. These investments generally take the form of equity or debt with conversion features and do not have readily determinable fair values. We initially record these investments at cost and adjust their fair value based on observable price changes, such as follow-on capital raises or secondary sales, and will also evaluate impacts to valuation from changing market conditions and underlying business performance. As of December 31, 2023, the carrying value of these investments was $3 million.
Cash and cash equivalents
Cash and cash equivalents include cash on hand and highly liquid investments with original maturities of three months or less and money market fund investments which are generally invested in U.S. government securities and are available to us on a daily basis. Fair values equal carrying values (Level 1).
Restricted cash
Restricted cash primarily includes interest-earning cash balances related to risk-sharing transactions with the Agencies, cash held at Servicing Investment entities, and cash held at consolidated Sequoia, HEI and CAFL Bridge entities for the purpose of distribution to investors and reinvestment. Due to the short-term nature of the restrictions, fair values approximate carrying values (Level 1).
Accrued interest receivable and payable
Accrued interest receivable and payable includes interest due on our assets and payable on our liabilities. Due to the short-term nature of when these interest payments will be received or paid, fair values approximate carrying values (Level 1).
Margin receivable
Margin receivable reflects cash collateral we have posted with our various derivative and debt counterparties as required to satisfy margin requirements. Fair values approximate carrying values (Level 2).
ABS issued
ABS issued includes asset-backed securities issued through the Legacy Sequoia, Sequoia, CAFL and HEI securitization entities, as well as securities issued by certain third-party Freddie Mac K-Series and SLST securitization entities that we consolidate. These instruments are generally illiquid in nature and trade infrequently. Significant inputs in the valuation analysis are predominantly Level 3, due to the nature of these instruments and the lack of readily available market quotes. For ABS issued, we utilize both market comparable pricing and discounted cash flow analysis valuation techniques. Relevant market indicators factored into the analysis include bid/ask spreads, the amount and timing of collateral credit losses, interest rates, and collateral prepayment rates. Estimated fair values incorporate market indicators as well as other significant unobservable inputs to generate discounted cash flows (Level 3). These cash flow models use significant unobservable inputs such as discount rate, prepayment rate, default rate, and loss severity. A decrease in credit losses or discount rates, or an increase in prepayment rates, would generally cause the fair value of the ABS issued to decrease (i.e., become a larger liability).
Financial Instruments Carried at Amortized Cost
Guarantee obligations
In association with our risk-sharing transactions with the Agencies, we have made certain guarantees which are carried on our balance sheet at amortized cost (Level 3).
Short-term and certain long-term debt (excluding convertible notes and trust preferred securities and subordinated notes)
Short-term debt includes our credit facilities for residential and business purpose loans and real estate securities as well as non-recourse short-term borrowings used to finance servicer advance investments, promissory notes and the current portion of long-term debt. As these borrowings are secured and subject to margin calls and as the rates on these borrowings reset frequently to market rates, we believe that carrying values approximate fair values (Level 2).
Borrowings under our subordinate securities financing facilities are secured by real estate securities and carried at unpaid principal balance net of any unamortized deferred issuance costs (Level 3). Borrowings under our non-recourse business purpose loans financing facilities are secured by BPL bridge loans and other BPL investments and carried at unpaid principal balance net of any unamortized deferred issuance costs (Level 3). Borrowings under our recourse business purpose loan financing facilities are secured by BPL term and bridge loans and carried at unpaid principal balance net of any unamortized deferred issuance costs (Level 3).
ABS issued
We account for certain ABS issued by securitizations we consolidate at amortized cost (Level 3).
Convertible notes
Convertible notes include unsecured convertible and exchangeable senior notes that are carried at their unpaid principal balance net of any unamortized deferred issuance costs. The fair value of the convertible notes is determined using quoted prices in generally active markets (Level 2).
Trust preferred securities and subordinated notes
Trust preferred securities and subordinated notes are carried at their unpaid principal balance net of any unamortized deferred issuance costs (Level 3).
