[3] Subsequent to the filing of the 10-Q for the three months ended March 31, 2015, the Company elected to early adopt ASU 2015-02 with an effective date of January 1, 2015. As a result of this adoption, all of the ZAIS Managed Entities which were consolidated in the 10-Q for the three months ended March 31, 2015 were deconsolidated. The March 31, 2015 figures above reflect the consolidated results of the Company for the three months ended March 31, 2015, subsequent to the adoption of ASU 2015-02.

[4] The treasury stock method is used to calculate incremental Class A common shares on potentially dilutive Class A common shares resulting from unvested Class B-0 Units granted in connection with and subsequent to the Business Combination and unvested RSUs granted to non-employee directors. These units are anti-dilutive and, consequently, have been excluded from the computation of diluted weighted average shares outstanding.

[5] Number of diluted shares outstanding takes into account non-controlling interests of ZGP that may be exchanged for Class A Common Stock under certain circumstances.

[6] Number of diluted shares outstanding for periods after the Business Combination (as defined in Note 1) takes into account non-controlling interests in ZAIS Group Parent, LLC that may be exchanged for Class A common stock under certain circumstances.

[7] Amount represents portion of the management fee income received from ZFC REIT that is payable to holders of Class B interests in ZAIS Group’s consolidated subsidiary ZAIS REIT Management.
