ANNALY CAPITAL MANAGEMENT, INC. AND SUBSIDIARIESItem 2. Management’s Discussion and Analysis 

generally represents the economic equivalent of the net interest income earned on the underlying Agency MBS less an implied financing cost.

TBA dollar roll transactions are accounted for under GAAP as a series of derivatives transactions. The fair value of TBA derivatives is based on methods similar to those used to value Agency MBS. We record TBA derivatives at fair value in our Consolidated Statements of Financial Condition and recognize periodic changes in fair value in Net gains (losses) on derivatives in our Consolidated Statements of Comprehensive Income (Loss), which includes both unrealized and realized gains and losses on derivatives.

TBA dollar roll income is calculated as the difference in price between two TBA contracts with the same terms but different settlement dates multiplied by the notional amount of the TBA contract. Although accounted for as derivatives, TBA dollar rolls capture the economic equivalent of net interest income, or carry, on the underlying Agency MBS (interest income less an implied cost of financing). TBA dollar roll income is reported as a component of Net gains (losses) on derivatives in the Consolidated Statements of Comprehensive Income (Loss).

Premium Amortization Expense

In accordance with GAAP, we amortize or accrete premiums or discounts into interest income for our Agency MBS, excluding interest-only securities, multifamily and reverse mortgages, taking into account estimates of future principal prepayments in the calculation of the effective yield. We recalculate the effective yield as differences between anticipated and actual prepayments occur. Using third party models 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. 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.

Our GAAP metrics include the unadjusted impact of amortization and accretion associated with this method. Certain of our non-GAAP metrics exclude the effect of the PAA, which quantifies the component of premium amortization representing the cumulative impact on prior periods, but not the current period, of quarter-over-quarter changes in estimated long-term Constant Prepayment
