Derivatives
Note 8 - Derivatives

    We enter into derivative transactions to manage our interest rate risk and agency mortgage rate exposures. We have agreements with our derivative counterparties that provide for the posting of collateral based on the fair values of our derivatives. Through this margin process, either we or our counterparties may be required to pledge cash or securities as collateral. Collateral requirements vary by counterparty and change over time based on the fair value, notional amount and remaining term of the contracts. Certain contracts provide for cross collateralization and cross default with repurchase agreements and other contracts with the same counterparty.

    Interest rate swap contracts are designed to lock in funding costs for repurchase agreements associated with our assets in such a way to help assure the realization of net interest margins. Such transactions are based on assumptions about prepayments which, if not realized, will cause transaction results to differ from expectations. Interest rate swaptions generally provide us the option to enter into an interest rate swap agreement at a certain point of time in the future with a predetermined notional amount, stated term and stated rate of interest in the fixed leg and interest rate index on the floating leg. Basis swap contracts allow us to exchange one floating interest rate basis for another, thereby allowing us to diversify our floating rate basis exposures.
 
    TBA Agency Securities are forward contracts for the purchase (“long position”) or sale (“short position”) of Agency Securities at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific Agency Securities delivered into the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association, are not known at the time of the transaction. We may enter into TBA Agency Securities as a means of hedging against short-term changes in interest rates. We may also enter into TBA Agency Securities as a means of acquiring or disposing of Agency Securities and we may from time to time utilize TBA dollar roll transactions to finance Agency Security purchases. We estimate the fair value of TBA Agency Securities based on similar methods used to value our Agency Securities.

    We have netting arrangements in place with all derivative counterparties pursuant to standard documentation developed by ISDA. We are also required to post or hold cash collateral based upon the net underlying market value of our open positions with the counterparty. A decline in the value of the open positions with the counterparty could result in the counterparties demanding additional collateral pledges or liquidation of some of the existing collateral to reduce borrowing levels. We manage this risk by maintaining an adequate balance of available cash and unpledged securities. An event of default or termination event under the standard ISDA would give our counterparty the option to terminate all repurchase transactions existing with us and require any amount due to be payable immediately. In addition, certain of our ISDAs contain a restriction that prohibits our leverage from exceeding twelve times our stockholders’ equity as well as termination events in the case of significant reductions in equity capital. During the year ended December 31, 2020, we received waivers from certain ISDA counterparties related to significant reductions in equity capital that would have otherwise caused a default or termination event.
    The following tables present information about the potential effects of netting our derivatives if we were to offset the assets and liabilities on the accompanying consolidated balance sheets. We currently present these financial instruments at their gross amounts and they are included in derivatives, at fair value on the accompanying consolidated balance sheets at December 31, 2020 and December 31, 2019.
