Announces Fourth Quarter 2017 Financial Results

NEW YORK - MFA Financial, Inc. (NYSE:MFA) today announced its financial results for the fourth quarter ended December 31, 2017.

Fourth Quarter 2017 and other highlights:

·                  MFA generated fourth quarter net income available to common shareholders of $96.8 million, or $0.24 per common share (based on 397.5 million weighted average common shares outstanding).  As of December 31, 2017, book value per common share was $7.70.

·                  Net income increased from the prior quarter due primarily to higher income on residential whole loans held at fair value, which exhibited mark to market gains and increased cash receipts.  In addition, CRT securities held at fair value increased in value as prices recovered after hurricane-related concerns in the third quarter.

·                  On January 31, 2018, MFA paid its fourth quarter 2017 dividend of $0.20 per share of common stock to shareholders of record as of December 28, 2017.

·                  MFA purchased more than $700 million of residential mortgage assets in the fourth quarter, including $554 million of residential whole loans.

Craig Knutson, MFA’s President and CEO, said, “In the fourth quarter, we continued to execute our strategy of targeted investment within the residential mortgage universe with a focus on credit sensitive assets.  We grew our portfolio slightly this quarter, as acquisitions exceeded run-off, which included opportunistic sales of $20.9 million of Legacy Non-Agency MBS that generated realized gains of $9.0 million.  As we have for over five years now, we continue to manage this portfolio through selective and strategic sales of positions.

“MFA remains well-positioned to generate attractive returns despite historically low interest rates.  Through our asset selection and hedging strategy, the estimated net effective duration, a gauge of MFA’s interest rate sensitivity, remains relatively low and measured 0.91 at quarter-end.  MFA’s book value per common share was unchanged during the quarter at $7.70 and increased during 2017 approximately 1% as our investment strategy continues to produce stable book value. Leverage, which reflects the ratio of our financing obligations to equity, was 2.3:1 at quarter-end.”

Mr. Knutson added, “MFA’s portfolio asset selection process continues to emphasize residential mortgage credit exposure while seeking to minimize sensitivity to interest rates.  As housing prices maintain their upward trend and borrowers repair their credit and balance sheets, MFA’s Legacy Non-Agency MBS portfolio continues to outperform our credit assumptions.  In the fourth quarter of 2017, we reduced our credit reserve on this portfolio by $17.1 million.  Also, our credit sensitive residential whole loans offer additional exposure to residential mortgage credit while affording us the opportunity to improve outcomes through sensible and effective servicing decisions.”

During the fourth quarter MFA successfully purchased more than $700 million of residential mortgage assets, including $554 million of residential whole loans.  Portfolio run-off in RPL/NPL MBS, which had been elevated for the past few quarters, returned to more normal levels during the fourth quarter.

MFA’s Legacy Non-Agency MBS had a face amount of $2.8 billion with an amortized cost of $2.0 billion and a net purchase discount of $806.5 million at December 31, 2017.  This discount consists of a $593.2 million credit reserve and other-than-temporary impairments and a $213.3 million net accretable discount.  We believe this credit reserve appropriately factors in remaining uncertainties regarding underlying mortgage performance and the potential impact on future cash flows.  Our Legacy Non-Agency MBS have underlying mortgage loans that are on average approximately twelve years seasoned and approximately 12.8% are currently 60 or more days delinquent.

The Agency MBS portfolio had an amortized cost basis of 103.8% of par as of December 31, 2017, and generated a 2.08% yield in the fourth quarter.  The Legacy Non-Agency MBS portfolio had an amortized cost of 71.2% of par as of December 31, 2017, and generated a loss-adjusted yield of 9.12% in the fourth quarter.  At the end of the fourth quarter, MFA held approximately $923.1 million of RPL/NPL MBS.  These securities had an amortized cost of 99.79% of par and generated a 4.27% yield for the quarter.  Our investments in CRT securities totaled $664.4 million at December 31, 2017, and generated a yield of 5.77% in the fourth quarter.  Values of our CRT securities increased during the quarter, reversing the declines experienced in the third quarter, as hurricane-related concerns subsided.

In addition, at December 31, 2017, our investments in credit sensitive residential whole loans totaled $2.2 billion.  Of this amount, $908.5 million is recorded at carrying value, or 88.4% of the interest-bearing

unpaid principal balance, and generated a loss-adjusted yield of 5.88% (5.43% net of servicing costs) during the quarter, and $1.3 billion is recorded at fair value on our consolidated balance sheet.  On this portion of the portfolio, we recorded gains for the quarter of approximately $41.4 million, primarily reflecting changes in the fair value of the underlying loans, coupon interest payments and other cash received during the quarter.

For the three months ended December 31, 2017, MFA’s costs for compensation and benefits and other general and administrative expenses were $9.3 million, or an annualized 1.14% of stockholders’ equity as of December 31, 2017.

The following table presents the weighted average prepayment speed on MFA’s MBS portfolio.

Table 1

(1)   All principal payments are considered to be prepayments for conditional prepayment rate (“CPR”) purposes.  RPL/NPL MBS are securitized financial instruments that are primarily backed by securitized re-performing and non-performing loans.  The majority of these securities are structured such that the coupon increases up to 300 basis points at 36 months from issuance or sooner.

As of December 31, 2017, under its swap agreements, MFA had a weighted average fixed-pay rate of interest of 2.04% and a floating receive rate of 1.50% on notional balances totaling $2.6 billion, with an average maturity of 27 months.

The following table presents MFA’s asset allocation as of December 31, 2017, and the fourth quarter 2017 yield on average interest-earning assets, average cost of funds and net interest rate spread for the various asset types.

ASSET ALLOCATION

(1)         The carrying value of such loans reflects the purchase price, accretion of income, cash received and provision for loan losses since acquisition.  At December 31, 2017, the fair value of such loans is estimated to be approximately $988.7 million.

(2)         Includes cash and cash equivalents and restricted cash, securities obtained and pledged as collateral, other assets, obligation to return securities obtained as collateral and other liabilities.

(3)         Represents the sum of borrowings under repurchase agreements and securitized debt as a multiple of net equity allocated.  The numerator of our Total Debt/Net Equity Ratio also includes the obligation to return securities obtained as collateral of $504.1 million and Senior Notes.

(4)         Yields reported on our interest earning assets are calculated based on the interest income recorded and the average amortized cost for the quarter of the respective asset.  At December 31, 2017, the amortized cost of our interest earning assets were as follows: Agency MBS - $2.8 billion; Legacy Non-Agency MBS - $2.0 billion; RPL/NPL MBS - $920.1 million; Credit Risk Transfer securities - $608.1 million; and Residential Whole Loans at carrying value - $908.5 million. In addition, the yield for residential whole loans at carrying value was 5.43% net of 45 basis points of servicing fee expense incurred during the quarter.  For GAAP reporting purposes, such expenses are included in Loan servicing and other related operating expenses in our statement of operations.  Interest payments received on residential whole loans at fair value is reported in Other Income as Net gain on residential whole loans held at fair value in our statement of operations.  Accordingly, no yield is presented as such loans are not included in interest earning assets for reporting purposes.

(5)         Average cost of funds includes interest on repurchase agreements and other advances, the cost of swaps and Senior Notes.  Agency cost of funds includes 43 basis points and Legacy Non-Agency cost of funds includes 45 basis points associated with swaps to hedge interest rate sensitivity on these assets.

At December 31, 2017, MFA’s $5.4 billion of Agency and Legacy Non-Agency MBS were backed by hybrid, adjustable and fixed-rate mortgages.  Additional information about these MBS, including average months to reset and three-month average CPR, is presented below:

Table 3

(1)         Excludes $923.1 million of RPL/NPL MBS.

(2)         Does not include principal payments receivable of $1.9 million.

(3)         Months to Reset is the number of months remaining before the coupon interest rate resets. At reset, the MBS coupon will adjust based upon the underlying benchmark interest rate index, margin and periodic or lifetime caps.  Months to Reset does not reflect scheduled amortization or prepayments.

(4)         3 month average CPR weighted by positions as of beginning of each month in the quarter.

(5)         Includes floating rate MBS that may be collateralized by fixed-rate mortgages.

(6)         Information presented based on data available at time of loan origination.
