Interest accrued but not paid is recognized as Interest receivable on the Consolidated Statements of Financial Condition. Interest income is presented as a separate line item on the Consolidated Statements of Comprehensive Income. Refer to the “Interest Income and Interest Expense” note for further discussion.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">For its securities, the Company recognizes coupon income, which is a component of interest income, based upon the outstanding principal amounts of the financial instruments and their contractual terms. 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="line-height:120%;padding-bottom:4px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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. See the Note “Interest Income and Interest Expense” for further discussion on interest.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company has made an accounting policy election not to measure an allowance for loans losses for accrued interest receivable. 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. Any interest written off that is recovered is recognized as interest income.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Refer to the “Interest Income and Interest Expense” Note for further discussion of interest income.</span></div>
