Anworth Announces Fourth Quarter 2011 Financial Results

SANTA MONICA, Calif.--(BUSINESS WIRE)--February 9, 2012--Anworth Mortgage Asset Corporation (NYSE: ANH) reported today core earnings available to common stockholders of $26.9 million, or $0.20 per diluted share, for the fourth quarter ended December 31, 2011, consisting primarily of $28.4 million of net income less $1.5 million of dividends paid to our preferred stockholders. This compares to core earnings of $29.1 million, or $0.22 per diluted share, for the third quarter ended September 30, 2011.

“Core earnings” represents a non-GAAP financial measure, which we define as GAAP net income excluding impairment losses on mortgage-backed securities, or MBS. For the three months ended December 31, 2011, there were no impairment losses on MBS.

On December 15, 2011, we declared a quarterly common stock dividend of $0.21 per share, which was payable on January 27, 2012 to our holders of common stock as of the close of business on December 30, 2011.

On a non-GAAP basis and during the three months ended December 31, 2011, our estimated taxable income, on which we base our common stock dividends, was $29 million, or $0.21 per diluted share. The difference between net income and our estimate of taxable income earned during the three months ended December 31, 2011 reflects the non-deductibility for income tax purposes of executive compensation of approximately $1.6 million, or $0.01 per share. A reconciliation of taxable earnings to net income available to common stockholders appears at the end of this news release.

At December 31, 2011 and September 30, 2011, our book value per share was $6.96 and $6.93, respectively.

Our investments consist of Agency MBS, which constituted essentially all of our portfolio at December 31, 2011. At December 31, 2011 and September 30, 2011, the fair value of our Agency MBS portfolio and its allocation was approximately as follows:

At December 31, 2011, our swap agreements had the following notional amounts (in thousands), weighted average interest rates and remaining terms (in months):

	December 31, 2011
	Notional Amount	Weighted Average Interest Rate		Remaining Term in Months
Less than 12 months	$520,000	3.92	%	5

Over 4 years	1,045,000	1.98		54
	$3,030,000	2.51	%	34

At December 31, 2011, our leverage multiple was 7.25x, which was an increase from our leverage multiple of 7.18x at September 30, 2011. The leverage multiple is based on common stockholders’ equity plus all Preferred Stock and the junior subordinated notes.

	December 31, 2011		September 30, 2011
Relative to Average Earning Assets During the Quarter:
Interest income earned	3.39	%	3.52	%
Amortization of premium	0.79	%	0.80	%
Average cost of funds on repurchase agreements and derivative instruments	1.18	%	1.15	%
Net interest rate spread	1.42	%	1.57	%

At December 31, 2011, stockholders’ equity available to common stockholders was approximately $933.8 million, or a book value of $6.96 per share, based on approximately 134.1 million shares of common stock outstanding at quarter end. The $933.8 million equals total stockholders’ equity of $982.3 million less the Series A Preferred Stock liquidating value of $46.9 million and less the difference between the Series B Preferred Stock liquidating value of $28.8 million and the proceeds from its sale of $27.2 million. At September 30, 2011, stockholders’ equity available to common stockholders was approximately $921.7 million, or a book value of $6.93 per share, based on approximately 133 million shares of common stock outstanding at quarter end. The $921.7 million equals total stockholders’ equity of $970.2 million less the Series A Preferred Stock liquidating value of $46.9 million and less the difference between the Series B Preferred Stock liquidating value of $29.8 million and the proceeds from its sale of $28.2 million.

Reconciliation of Non-GAAP Financial Measures

The table below presents the reconciliation of net income to common stockholders to estimated taxable income, which non-GAAP financial measure excludes the non-deductibility of components of discretionary and incentive executive compensation. The Company’s management believes that this financial measure, when considered together with our GAAP financial measures, provides information that is useful to investors in understanding the differences between GAAP earnings and estimated taxable earnings (which is the basis upon which our Board of Directors declares our common stock dividends). Management also believes that this financial measure enhances the ability of investors to analyze the Company’s operating trends and to better understand its operating performance. This financial measure should not be used as a substitute in assessing the Company’s results of operations and financial condition at December 31, 2011. An analysis of any non-GAAP financial measure should be used in conjunction with results presented in accordance with GAAP.
