NLY 2023 Annual Report

Critical Accounting Estimates The preparation of our consolidated financial statement in accordance with generally accepted accounting principles in the United States requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ materially from these estimates and changes in assumptions could have a significant effect on the consolidated financial statements. Our critical accounting policies that require us to make significant judgments or estimates are described below. For more information on these critical accounting policies and other significant accounting policies, refer to the Note titled “Significant Accounting Policies” in the Notes to the Consolidated Financial Statements included in Item 15. “Exhibits, Financial Statement Schedules.” Valuation of Financial Instruments Residential Securities Description: We carry residential securities at estimated fair value. There is an active market for our Agency mortgage-backed securities, CRT securities and non-Agency mortgage-backed securities. Judgments and Uncertainties: Since we primarily invest in securities that can be valued using quoted prices for actively traded assets, there is a high degree of observable inputs and less subjectivity in measuring fair value. Internal fair values are determined using quoted prices from the TBA securities market, the Treasury curve and the underlying characteristics of the individual securities, which may include coupon, periodic and life caps, reset dates and the expected life of the security. While prepayment rates may be difficult to predict and require estimation and judgment in the valuation of Agency mortgage-backed securities, we use several third party models to validate prepayment speeds used in fair value measurements of residential securities. All internal fair values are compared to external pricing sources and/or dealer quotes to determine reasonableness. Additionally, securities used as collateral for repurchase agreements are priced daily by counterparties to ensure sufficient collateralization, providing additional verification of our internal pricing. Sensitivity of Estimates to Change: Changes in underlying assumptions used in estimating fair value impact the carrying value of the residential securities as well as their yield. For example, an increase in CPR would decrease the carrying value and yield of our Agency mortgage-backed securities. Our valuations are most sensitive to changes in interest rate, which also impacts prepayment speeds. Refer to the Experienced and Projected Long-Term CPR, Financial Condition – Residential Securities and the interest rate sensitivity and interest rate and MBS spread shock analysis and discussions within this Item 7. for further information. Residential Mortgage Loans Description: We elected to account for Residential Mortgage Loans at fair value. There is an active market for the residential whole loans in which we invest. Judgments and Uncertainties: Since we primarily invest in residential loans that can be valued using actively quoted prices for similar assets, there are observable inputs in measuring fair value. Internal fair values are determined using quoted prices for similar market transactions, the swap curve and the underlying characteristics of the individual loans, which may include loan term, coupon, and reset dates. While prepayment rates may be difficult to predict and are a significant estimate requiring judgment in the valuation of residential whole loans, we validate prepayment speeds against those provided by independent pricing analytic providers specializing in residential mortgage loans. Internal fair values are generally compared to external pricing sources to determine reasonableness. Sensitivity of Estimates to Change: Changes to model assumptions, including prepayment speeds may significantly impact the fair value estimate of residential mortgage loans as well as unrealized gains and losses and yield on these assets. Our valuations are most sensitive to changes in interest rate, which also impacts prepayment speeds. Refer to the interest rate sensitivity and interest rate shock analysis and discussions within this Item 7. for further information. MSR Description: We elected to account for MSR at fair value. The market for MSR is considered less active and transparent compared to securities. As such fair value estimates for our investment in MSR are obtained from models, which use significant unobservable inputs in their valuations. Judgments and Uncertainties: These valuations primarily utilize discounted cash flow models that incorporate unobservable market data inputs including prepayment rates, delinquency levels, costs to service and discount rates. Model valuations are then compared to valuations obtained from third party pricing providers. Management reviews the valuations received from ANNALY CAPITAL MANAGEMENT, INC. AND SUBSIDIARIES Item 7.
