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 March 31, 2020 and December 31, 2019 .

At March 31, 2020, the fair value of securities we owned at the consolidated Sequoia, Freddie Mac SLST, Freddie Mac K-Series, and CAFL entities was $148 million , $307 million , $23 million , and $167 million , respectively. (2) 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). (3) Represents the probability of a full payout of contingent purchase consideration. (4) As a market convention, certain securities are priced to a no-loss yield and therefore do not include default and loss severity assumptions. (5) The weighted average input values for all loan types are based on the unpaid principal balance. The weighted average input values for all other assets and liabilities are based on relative fair value. 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 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 at Redwood Estimated fair values for residential loans are determined using third-party committed sales prices or models that incorporate various observable inputs, including pricing information from whole loan sales and securitizations. 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 to be announced ("TBA") prices and indexed swap rates for fixed-rate loans and indexed swap rates for hybrid loans (Level 3). Significant pricing inputs obtained from market securitization activity include indicative spreads to indexed TBA prices for senior residential mortgage-backed securities ("RMBS") and indexed swap rates for subordinate RMBS, 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. Residential loans, business purpose residential loans, and multifamily loans at consolidated entities We have elected to account for our consolidated securitization entities as CFEs 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 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. Business purpose residential loans Business purpose residential loans include single-family rental loans and residential bridge loans that are generally illiquid in nature and trade infrequently. Significant inputs in the valuation analysis are predominantly Level 3 in nature, due to the lack of readily available market quotes and related inputs. Estimated fair values for our single-family rental loans are determined using models that incorporate various inputs, including pricing information from market comparable securitizations. Certain significant inputs in these models are considered unobservable and are therefore Level 3 in nature. Significant pricing inputs obtained from market activity include indicative spreads to indexed 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. Prices for our residential bridge loans are determined using discounted cash flow modeling, which incorporates a primary significant unobservable input of discount rate. These assets would generally decrease in value based upon an increase in the discount rate. 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 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. Estimated fair values are based on applying the market indicators to generate discounted cash flows (Level 3). These 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. As part of our securities valuation process, we request and consider indications of value from third-party securities dealers. For purposes of pricing our securities at March 31, 2020 , we received dealer price indications on 78% of our securities, representing 91% of our carrying value. Once we receive the price indications from dealers, they are compared to other relevant market inputs, such as actual or comparable trades, and the results of our discounted cash flow analysis. In circumstances where relevant market inputs cannot be obtained, increased reliance on discounted cash flow analysis and management judgment are required to estimate fair value. Derivative assets and liabilities Our derivative instruments include swaps, swaptions, TBAs, interest rate futures, loan purchase commitments ("LPCs"), and interest rate lock commitments ("IRLCs"). 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 single-family rental loans are estimated based on the estimated fair values of the underlying loans (as described in " Residential loans at Redwood " and " Business purpose residential 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). For other derivatives, valuations are based on various factors such as liquidity, bid/ask spreads, and credit considerations for which we rely on available market inputs. In the absence of such inputs, management’s best estimate is used (Level 3). 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 included prepayment rate (of the loans underlying the investments), mortgage servicing income, servicer advance WAL (the weighted-average expected remaining life of servicer advances), and discount rate. These assets would generally decrease in value based upon an increase in prepayment rates, an increase in servicer advance WAL, or an increase in discount rate, or a decrease in mortgage servicing income. 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. As part of our MSR valuation process, we received a valuation estimate from a third-party valuations firm. In the aggregate, our internal valuation of the MSRs were within 5% of the third-party valuation. 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 included 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. Shared Home Appreciation Options Estimated fair values for shared home appreciation options 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 rate, 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 expected future home values combined with a decrease in prepayment rates, would generally reduce the estimated fair value of the shared home appreciation options. FHLBC stock Our Federal Home Loan Bank ("FHLB") member subsidiary is required to purchase FHLBC stock under a borrowing agreement between our FHLB-member subsidiary and the FHLBC. Under this agreement, the stock is redeemable at face value, which represents the carrying value and fair value of the stock (Level 2). Guarantee asset The guarantee asset represents the estimated fair value of cash flows we are contractually entitled to receive related to a risk-sharing arrangement with Fannie Mae. Significant inputs in the valuation analysis are Level 3, due to the nature of this asset and the lack of market quotes. The fair value of the guarantee asset is determined using a discounted cash flow model, for which significant unobservable inputs include assumed future prepayment rates and market discount rate (Level 3). An increase in prepayment rates or discount rate would generally reduce the estimated fair value of the guarantee asset. Pledged collateral Pledged collateral consists of cash and U.S. Treasury securities held by a custodian in association with certain agreements we have entered into. Treasury securities are carried at their fair value, which is determined using quoted prices in active markets (Level 1). Cash and cash equivalents Cash and cash equivalents include cash on hand and highly liquid investments with original maturities of three months or less. 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 in association with borrowings from the FHLBC, cash held at Servicing Investment entities, and cash held at consolidated Sequoia 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). Real estate owned Real estate owned ("REO") includes properties owned in satisfaction of foreclosed loans. Fair values are determined using available market quotes, appraisals, broker price opinions, comparable properties, or other indications of value (Level 3). 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). Contingent consideration Contingent consideration is related to our acquisition of 5 Arches and is estimated and recorded at fair value as part of purchase consideration. Each reporting period we estimate the change in fair value of the contingent consideration, and such change is recognized in our consolidated statements of income (loss), unless it is determined to be a measurement period adjustment. The estimate of the fair value of contingent consideration requires significant judgment and assumptions to be made about future operating results, discount rates, and probabilities of projected operating result scenarios (Level 3). Short-term debt Short-term debt includes our credit facilities for residential and business purpose residential loans and real estate securities as well as non-recourse short-term borrowings used to finance servicer advance investments. As these borrowings are secured and subject to margin calls and as the rates on these borrowings reset frequently to mar |
