In addition, the Company amortizes or accretes premiums or discounts into interest income for its Agency mortgage-backed securities (other than interest-only securities, multifamily and reverse mortgages), taking into account estimates of future principal prepayments in the calculation of the effective yield. The Company recalculates the effective yield as differences between anticipated and actual prepayments occur. Using third-party model and market information to project future cash flows and expected remaining lives of securities, the effective interest rate determined for each security is applied as if it had been in place from the date of the security’s acquisition. The amortized cost of the security is then adjusted to the amount that would have existed had the new effective yield been applied since the acquisition date, which results in a cumulative premium amortization adjustment in each period. The adjustment to amortized cost is offset with a charge or credit to interest income. Changes in interest rates and other market factors will impact prepayment speed projections and the amount of premium amortization recognized in any given period.</span></div><div style="margin-bottom:3pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Premiums or discounts associated with the purchase of Agency interest-only securities, reverse mortgages and residential credit securities are amortized or accreted into interest income based upon current expected future cash flows with any adjustment to yield made on a prospective basis.</span></div><div style="margin-bottom:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Premiums and discounts associated with the purchase of residential mortgage loans and with those transferred or pledged to securitization trusts are primarily amortized or accreted into interest income over their estimated remaining lives using the effective interest rates inherent in the estimated cash flows from the mortgage loans. Amortization of premiums and accretion of discounts are presented in Interest income in the Consolidated Statements of Comprehensive Income (Loss). </span></div><div style="margin-bottom:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">If collection of a loan’s principal or interest is in doubt or the loan is 90 days or more past due, interest income is not accrued. For nonaccrual status loans carried at fair value or held for sale, interest is not accrued but is recognized on a cash basis. For nonaccrual status loans carried at amortized cost, if collection of principal is not in doubt but collection of interest is in doubt, interest income is recognized on a cash basis. If collection of principal is in doubt, any interest received is applied against principal until collectability of the remaining balance is no longer in doubt; at that point, any interest income is recognized on a cash basis. Generally, a loan is returned to accrual status when the borrower has resumed paying the full amount of the scheduled contractual obligation, if all principal and interest amounts contractually due are reasonably assured of repayment within a reasonable period of time and there is a sustained period of repayment performance by the borrower.

If interest receivable is deemed to be uncollectible or not collected within 90 days of its contractual due date for commercial loans or 120 days for corporate debt carried at amortized cost, it is written off through a reversal of interest income.

Allowance for loan losses are written off in the period the loans are deemed uncollectible.</span></div><div style="margin-bottom:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Given the unique nature of each underlying borrower and any collateral, the Company assesses an allowance for each individual loan held-for-investment. A provision is established at origination or acquisition that reflects management’s estimate of the total expected credit loss over the expected life of the loan. In estimating the lifetime expected credit losses, management utilizes a probability of default and loss given default methodology (“Loss Given Default methodology”), which considers projected economic conditions over the reasonable and supportable forecast period. The forecast incorporates primarily market-based assumptions including, but not limited to, forward interest rate curves, unemployment rate estimates and certain indexes sourced from third party vendors. For any remaining period of the expected life of the loan after the reasonable and supportable period, the Company reverts to historical losses on a straight-line basis. Management uses third-party vendors’ loan pool data for loans with similar risk characteristics to estimate historical losses given the limited loss history of the Company’s loan portfolio. Changes in the lifetime expected credit loss are reflected in Loan loss (provision) reversal in the Consolidated Statements of Comprehensive Income (Loss).</span></div><div style="margin-bottom:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For loans experiencing credit deterioration, the Company may use a different methodology to determine the expected credit losses such as a discounted cash flow analysis. For collateral-dependent loans, if foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for any selling costs, if applicable. Additionally, the Company may elect the practical expedient for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty by measuring the allowance as the difference between the fair value of the collateral, less costs to sell, if applicable, and the amortized cost basis of the financial asset at the reporting date. The Company’s commercial loans are collateralized by commercial real estate including, but not limited to, multifamily real estate, office and retail space, hotels and industrial space. At origination, the fair value of the collateral generally exceeds the principal loan balance.</span></div><div style="margin-bottom:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Management assesses the credit quality of the portfolio and adequacy of loan loss reserves on a quarterly basis, or more frequently as necessary. Significant judgment is required in this analysis. Depending on the expected recovery of its investment, the Company considers the estimated net recoverable value of the loans as well as other factors, including but not limited to the fair value of any collateral, the amount and the status of any senior debt, the prospects for the borrower and the competitive landscape where the borrower conducts business. To determine if loan loss allowances are required on investments in corporate debt, the Company reviews the monthly and/or quarterly financial statements of the borrowers, verifies loan compliance packages, if applicable, and analyzes current results relative to budgets and sensitivities performed at inception of the investment. Because these determinations are based upon projections of future economic events, which are inherently subjective, the amounts ultimately realized may differ materially from the carrying value as of the reporting date.</span></div>The Company may be exposed to various levels of credit risk depending on the nature of its investments and credit enhancements, if any, supporting its assets. The Company’s core investment process includes procedures related to the initial approval and periodic monitoring of credit risk and other risks associated with each investment. The Company’s investment underwriting procedures include evaluation of the underlying borrowers’ ability to manage and operate their respective properties or companies. Management reviews loan-to-value metrics at origination or acquisition of a new investment and if events occur that trigger re-evaluation by management.
