Equity Compensation Plan	NOTE 13. EQUITY COMPENSATION PLAN 2014 Equity Compensation Plan At our 2014 annual meeting of stockholders held on May 22, 2014, our stockholders approved the adoption of the 2014 Equity Compensation Plan, or the 2014 Equity Plan, which replaced the Anworth Mortgage Asset Corporation 2004 Equity Compensation Plan, or the 2004 Plan, due to its expiration. We filed a registration statement on Form S-8 on August 5, 2014 to register up to an aggregate of 2,000,000 shares of our common stock to be issued pursuant to the 2014 Plan. The 2014 Plan decreased the aggregate share reserve from 3,500,000 shares that were available under the 2004 Plan to 2,000,000 shares of our registered common stock available under the 2014 Plan. The 2014 Plan authorizes our board of directors, or a committee of our board of directors, to grant Dividend Equivalent Rights, or DERs, or phantom shares, which qualify as performance-based awards under Section 162(m) of the Code. Unlike the 2004 Equity Plan, however, the 2014 Equity Plan does not provide for automatic increases in the aggregate share reserve or the number of shares remaining available for grant and only provides for the granting of DERs or phantom shares. During the three months ended September 30, 2015, we issued 8,000 restricted stock units with associated grants of 8,000 DERs under the 2014 Plan. Certain of our former officers have previously been granted restricted stock and other equity incentive awards, including DERs, in connection with their service to us. In connection with the Externalization, certain of the agreements under which our former officers have been granted equity awards were modified so that such agreements will continue with respect to our former officers after they became officers and employees of our Manager. As a result, these awards and any future grants will be accounted for as non-employee awards. In addition, as officers and employees of our Manager, they will continue to be eligible to receive equity incentive awards under equity incentive plans in effect now or in the future. In October 2005, our board of directors approved the grant of an aggregate of 200,780 shares of restricted stock to various officers under the 2004 Equity Compensation Plan. The restricted stock vests 10% per year on each anniversary date for a ten-year period and shall also vest immediately upon the death of the grantee or upon the grantee reaching age 65. We amortize the restricted stock over the vesting period, which is the lesser of ten years or the remaining number of years to age 65. Upon the expiration of the 2004 Plan, this grant is now being accounted for under the 2014 Plan. In October 2006, our board of directors approved a grant of an aggregate of 197,362 shares of performance-based restricted stock to various officers under the 2004 Plan. Upon the expiration of the 2004 Plan, this grant is now being accounted for under the 2014 Plan. We recognize the expense related to restricted stock over the ten-year vesting period. During the three and nine months ended September 30, 2015, we expensed approximately $24 thousand and $73 thousand, respectively, related to these restricted stock grants. During the three and nine months ended September 30, 2014, we expensed approximately $24 thousand and $72 thousand, respectively, related to these restricted stock grants. Under the Anworth Mortgage Asset Corporation 2007 Dividend Equivalent Rights Plan, or the 2007 DER Plan, a dividend equivalent right, or DER, is a right to receive amounts equal in value to the dividend distributions paid on a share of our common stock. DERs are paid in either cash or shares of our common stock, whichever is specified by our Compensation Committee at the time of grant, at such times as dividends are paid on shares of our common stock during the period between the date a DER is issued and the date the DER expires or earlier terminates. These DERs are not attached to any stock and only have the right to receive the same cash distribution per common share distributed to our common stockholders during the term of the grant. All of these grants have a five-year term from the date of the grant. During the three and nine ended months September 30, 2015, we paid or accrued $94 thousand and $265 thousand, respectively, related to DERs granted. During the three and nine ended months September 30, 2014, we paid or accrued $80 thousand and $243 thousand, respectively, related to DERs granted.

NOTE 13. EQUITY COMPENSATION PLAN

2014 Equity Compensation Plan

At our 2014 annual meeting of stockholders held on May 22, 2014, our stockholders approved the adoption of the 2014 Equity Compensation Plan, or the 2014 Equity Plan, which replaced the Anworth Mortgage Asset Corporation 2004 Equity Compensation Plan, or the 2004 Plan, due to its expiration. We filed a registration statement on Form S-8 on August 5, 2014 to register up to an aggregate of 2,000,000 shares of our common stock to be issued pursuant to the 2014 Plan. The 2014 Plan decreased the aggregate share reserve from 3,500,000 shares that were available under the 2004 Plan to 2,000,000 shares of our registered common stock available under the 2014 Plan. The 2014 Plan authorizes our board of directors, or a committee of our board of directors, to grant Dividend Equivalent Rights, or DERs, or phantom shares, which qualify as performance-based awards under Section 162(m) of the Code. Unlike the 2004 Equity Plan, however, the 2014 Equity Plan does not provide for automatic increases in the aggregate share reserve or the number of shares remaining available for grant and only provides for the granting of DERs or phantom shares. During the three months ended September 30, 2015, we issued 8,000 restricted stock units with associated grants of 8,000 DERs under the 2014 Plan.

Certain of our former officers have previously been granted restricted stock and other equity incentive awards, including DERs, in connection with their service to us. In connection with the Externalization, certain of the agreements under which our former officers have been granted equity awards were modified so that such agreements will continue with respect to our former officers after they became officers and employees of our Manager. As a result, these awards and any future grants will be accounted for as non-employee awards. In addition, as officers and employees of our Manager, they will continue to be eligible to receive equity incentive awards under equity incentive plans in effect now or in the future.

In October 2005, our board of directors approved the grant of an aggregate of 200,780 shares of restricted stock to various officers under the 2004 Equity Compensation Plan. The restricted stock vests 10% per year on each anniversary date for a ten-year period and shall also vest immediately upon the death of the grantee or upon the grantee reaching age 65. We amortize the restricted stock over the vesting period, which is the lesser of ten years or the remaining number of years to age 65. Upon the expiration of the 2004 Plan, this grant is now being accounted for under the 2014 Plan.

In October 2006, our board of directors approved a grant of an aggregate of 197,362 shares of performance-based restricted stock to various officers under the 2004 Plan. Upon the expiration of the 2004 Plan, this grant is now being accounted for under the 2014 Plan.

We recognize the expense related to restricted stock over the ten-year vesting period. During the three and nine months ended September 30, 2015, we expensed approximately $24 thousand and $73 thousand, respectively, related to these restricted stock grants. During the three and nine months ended September 30, 2014, we expensed approximately $24 thousand and $72 thousand, respectively, related to these restricted stock grants.

Under the Anworth Mortgage Asset Corporation 2007 Dividend Equivalent Rights Plan, or the 2007 DER Plan, a dividend equivalent right, or DER, is a right to receive amounts equal in value to the dividend distributions paid on a share of our common stock. DERs are paid in either cash or shares of our common stock, whichever is specified by our Compensation Committee at the time of grant, at such times as dividends are paid on shares of our common stock during the period between the date a DER is issued and the date the DER expires or earlier terminates. These DERs are not attached to any stock and only have the right to receive the same cash distribution per common share distributed to our common stockholders during the term of the grant. All of these grants have a five-year term from the date of the grant. During the three and nine ended months September 30, 2015, we paid or accrued $94 thousand and $265 thousand, respectively, related to DERs granted. During the three and nine ended months September 30, 2014, we paid or accrued $80 thousand and $243 thousand, respectively, related to DERs granted.
