Financial Derivatives

Financial Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages certain risks associated with its investments and borrowings, including interest rate, credit, liquidity, and foreign exchange rate risk primarily by managing the amount, sources, and duration of its investments and borrowings, and through the use of derivative financial instruments. The Company's derivative financial instruments are used to manage differences in the amount, timing, and duration of its known or expected cash receipts and its known or expected cash payments principally related to its investments and borrowings.

The following table details the fair value of the Company's holdings of financial derivatives as of June 30, 2023 and December 31, 2022:

TBAs

The Company transacts in the forward settling TBA market. Pursuant to these TBA transactions, the Company agrees to purchase or sell, for future delivery, Agency RMBS with certain principal and interest terms and certain types of underlying collateral, but the particular Agency RMBS to be delivered is not identified until shortly before the TBA settlement date. TBAs are generally liquid, have quoted market prices, and represent the most actively traded class of MBS. The Company uses TBAs to mitigate interest rate risk, usually by taking short positions. The Company also invests in TBAs as a means of acquiring additional exposure to Agency RMBS, or for investment purposes, including holding long positions.

The Company does not usually take delivery of TBAs; rather, it settles the associated receivable and payable with its trading counterparties on a net basis. Transactions with the same counterparty for the same TBA that result in a reduction of the position are treated as extinguished.

As of June 30, 2023 and December 31, 2022, the Company had outstanding TBA purchase and sale contracts as follows:

From time to time the Company enters into credit derivative contracts for which the Company sells credit protection ("written credit derivatives"). As of June 30, 2023 and December 31, 2022, all of the Company's open written credit derivatives were credit default swaps on either mortgage/asset-backed indices (ABX and CMBX indices) or corporate bond indices (CDX), collectively referred to as credit indices, or on individual corporate bonds, for which the Company receives periodic payments at fixed rates from credit protection buyers, and is obligated to make payments to the credit protection buyer upon the occurrence of a "credit event" with respect to underlying reference assets.

Written credit derivatives held by the Company at June 30, 2023 and December 31, 2022 are summarized below:

Credit Derivatives	June 30, 2023		December 31, 2022
(In thousands)
Fair Value of Written Credit Derivatives, Net	$	(5)	$	11
Notional Value of Written Credit Derivatives (1)	2,384		2,355

(1)The notional value is the maximum amount that a seller of credit protection would be obligated to pay, and a buyer of credit protection would receive, upon occurrence of a "credit event." Movements in the value of credit default swap transactions may require the Company or the counterparty to post or receive collateral. Amounts due or owed under credit derivative contracts with an International Swaps and Derivatives Association, or "ISDA," counterparty may be offset against amounts due or owed on other credit derivative contracts with the same ISDA counterparty. As a result, the notional value of written credit derivatives involving a particular underlying reference asset or index has been reduced (but not below zero) by the notional value of any contracts where the Company has purchased credit protection on the same reference asset or index with the same ISDA counterparty.

A credit default swap on a credit index or a corporate bond typically terminates at the stated maturity date in the case of corporate indices or bonds, or, in the case of ABX and CMBX indices, the date that all of the reference assets underlying the index are paid off in full, retired, or otherwise cease to exist. Implied credit spreads may be used to determine the market value of such contracts and are reflective of the cost of buying/selling credit protection. Higher spreads would indicate a greater likelihood that a seller will be obligated to perform (i.e., make protection payments) under the contract. In situations where the credit quality of the underlying reference assets has deteriorated, the percentage of notional values that would be paid up front to enter into a new such contract ("points up front") is frequently used as an indication of credit risk. Credit protection sellers entering the market in such situations would expect to be paid points up front corresponding to the approximate fair value of the contract. As of June 30, 2023, the implied credit spread on the Company's outstanding written credit derivative was 335 basis points; as of December 31, 2022, implied credit spread on the Company's written credit derivative was 310 basis points. Excluded from these spread ranges are contracts outstanding for which the individual spread is greater than 2,000 basis points. The Company believes that these contracts would be quoted based on estimated points up front. The total fair value of contracts with individual implied credit spreads in excess of 2,000 basis points was $(33) thousand as of both June 30, 2023 and December 31, 2022. Estimated points up front on these contracts as of both June 30, 2023 and December 31, 2022 ranged between 46.3 and 88.8. Total net up-front payments (paid) or received relating to written credit derivatives outstanding as of both June 30, 2023 and December 31, 2022 were $0.8 million.
