The cost of financing on interest rate swaps held to mitigate interest rate risk associated with the company’s outstanding borrowings includes interest spread income/expense and amortization of upfront payments made or received upon entering into interest rate swap agreements and is calculated using average borrowings balance as the denominator.

The cost of financing on U.S. Treasury futures held to mitigate interest rate risk associated with the company’s outstanding borrowings is calculated using average borrowings balance as the denominator.

The market-driven value changes adjustment for each of RMBS and other Agency securities, MSR, swap and swaptions and TBA represents unexpected price changes for the referenced period. As defined, the calculation of IXM includes modeled price changes that are measured daily based on a “Realized Forwards” methodology, which includes the assumption that spreads, forward interest rates, shape of the term structure and volatility factored into the previous day ending fair value are unchanged. Unexpected price changes represent the differences between (a) actual spreads, forward interest rates, shape of the term structure and volatility, and (b) the spreads, forward interest rates, shape of the term structure and volatility that were factored into the previous day ending fair value. Unexpected price changes are measured daily and used to determine the portion of actual market price changes not attributable to modeled price changes. The reported market-driven value changes adjustment for each of RMBS and other Agency securities, MSR, swap and swaptions and TBA is the sum of all daily unexpected price changes for the referenced period. Please refer to end notes (2) through (5) below for further information.

RMBS and other Agency securities market-driven value changes refers to the sum of interest income, realized and unrealized gains and losses on RMBS and other Agency securities, less the sum of the realization of RMBS and other Agency securities cash flows which incorporates actual prepayments, changes in RMBS and other Agency securities accrued interest, and modeled price changes. Modeled price changes are measured daily based on a “Realized Forwards” methodology, which includes the assumption that spreads, forward interest rates, shape of the term structure and volatility factored into the previous day ending fair value are unchanged. RMBS and other Agency securities includes inverse interest-only Agency RMBS which are accounted for as derivative instruments in accordance with GAAP.

MSR market-driven value changes refers to the sum of servicing income, servicing expenses, realized and unrealized gains and losses on MSR, less the sum of the realization of MSR cash flows which incorporates actual prepayments, servicing income and servicing expenses, and modeled price changes. Modeled price changes are measured daily based on a “Realized Forwards” methodology, which includes the assumption that spreads, forward interest rates, shape of the term structure and volatility factored into the previous day ending fair value are unchanged.

Swap and swaption market-driven value changes refers to the net interest spread and realized and unrealized gains and losses on interest rate swap and swaption agreements, less the swaps daily IXM that is equal to the previous day ending fair value multiplied by the overnight SOFR and swaptions daily IXM that is equal to the previous day ending fair value multiplied by the realized forward rate.

TBA market-driven value changes refers to the total realized and unrealized gains and losses, less the daily zero-volatility OAS less the implied repo spread, multiplied by the previous day ending fair value.

Certain operating expenses predominantly consists of expenses incurred in connection with the company’s ongoing litigation with PRCM Advisers LLC. It also includes certain transaction expenses incurred in connection with the company’s acquisition of RoundPoint Mortgage Servicing LLC.

Income Excluding Market-Driven Value Changes, or IXM, is a non-GAAP measure defined as total comprehensive income attributable to common stockholders, excluding market-driven value changes on the aggregate portfolio, provision for income taxes associated with market-driven value changes, certain operating expenses and gains on the repurchase and retirement of preferred stock and convertible senior notes. As defined, IXM includes the realization of portfolio cash flows which incorporates actual prepayments, changes in portfolio accrued interest, servicing income and servicing expenses, and certain modeled price changes. These modeled price changes are measured daily based on a “Realized Forwards” methodology, which includes the assumption that spreads, forward interest rates, shape of the term structure and volatility factored into the previous day ending fair value are unchanged. Assumptions for spreads, forward interest rates, shape of the term structure, volatility and the previous day ending fair value include applicable market data, data from third-party brokers and pricing vendors and management’s assessment. This applies to RMBS, MSR and derivatives, as applicable, and is net of all operating expenses and provision for income taxes associated with IXM. The purpose of presenting IXM, and the various adjustments related to market-driven value changes and certain legal expenses and acquisition transaction costs, is to provide management, analysts and investors with a profit and loss attribution that allows them to better understand the sources of returns from the company’s investment portfolio, operating expenses and tax expenses. IXM provides supplemental information to assist investors in analyzing the company’s results of operations and helps facilitate comparisons to industry peers. IXM is one of several measures the company’s board of directors considers to determine the amount of dividends to declare on the company’s common stock and should not be considered an indication of taxable income or as a proxy for the amount of dividends the company may declare.
