Great Ajax Corp., a Maryland corporation (the “Company”), is an externally managed real estate company formed on January 30, 2014 and capitalized on March 28, 2014 by its then sole stockholder, Aspen Yo LLC (“Aspen Yo”), a company affiliated with the Aspen Capital companies (“Aspen Capital”). The Company was formed to facilitate capital raising activities and to operate as a mortgage real estate investment trust. The Company focuses primarily on acquiring, investing in and managing a portfolio of re-performing and non-performing mortgage loans secured by single-family residences and, to a lesser extent, single-family properties. Re-performing loans are loans on which at least five of the seven most recent payments have been made, or the most recent payment has been made and accepted pursuant to an agreement, or the full dollar amount to cover at least five payments has been paid in the last seven months. Non-performing loans are those loans on which the most recent three payments have not been made. The Company also invests in loans secured by smaller multi-family residential and commercial mixed use retail/residential properties, as well as in the properties directly. The Company’s manager is Thetis Asset Management LLC (the “Manager” or “Thetis”), an affiliated company. The Company owns 19.8% of the Manager. The Company’s mortgage loans and real properties are serviced by Gregory Funding LLC (“Gregory” or “Servicer”), also an affiliated company. The Company expects to qualify and will elect to be taxed as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended (the “Code”), commencing with the year ended December 31, 2014.

The Company conducts substantially all of its business through its operating partnership, Great Ajax Operating Partnership L.P., a Delaware limited partnership, and its subsidiaries. The Company, through a wholly owned subsidiary, is the sole general partner of the operating partnership. GA-TRS LLC, or Thetis TRS, is a wholly owned subsidiary of the operating partnership that owns the equity interest in the Manager. The Company elected to treat Thetis TRS as a “taxable REIT subsidiary” (“TRS”) under the Code. In September 2014, the Company formed Great Ajax Funding LLC, a wholly owned subsidiary of the operating partnership, to act as the depositor of mortgage loans into securitization trusts and to hold the subordinated securities issued by such trusts and any additional trusts the Company may form for additional securitizations. The Company generally securitizes its mortgage loans and retains subordinated securities from the securitizations. In November 2014, the Company formed AJX Mortgage Trust I, a wholly owned subsidiary of the operating partnership, in connection with a repurchase facility. In addition, the Company, through its operating partnership, holds real estate owned properties (“REO”) acquired upon the foreclosure or other settlement of its owned non-performing loans, as well as through outright purchases. On February 1, 2015, the Company formed GAJX Real Estate LLC, as a wholly owned subsidiary of the operating partnership, to own, maintain, improve and sell REO properties. The Company has elected to treat GAJX Real Estate LLC as a TRS under the Code.

The Company commenced its operations following the completion of its initial private offering in July 2014. On July 8, 2014, the Company closed a private offering, pursuant to which the Company sold 8,213,116 shares of common stock and 453,551 Class A Units of the operating partnership (the “OP Units”), which are redeemable on a 1-for-1 basis into shares of its common stock after one year of ownership. On August 1, 2014, the Company closed the sale of an additional 263,570 shares of common stock and 14,555 OP Units pursuant to the exercise of the option to purchase additional shares granted to the initial purchaser and placement agent. The purchase price per share and per OP Unit was $15.00. In these offerings, which are referred to collectively as the “Original Private Placement,” the net proceeds, including from the additional shares purchased pursuant to the option to purchase additional shares and OP Units, after deducting the initial purchaser’s discount and placement fee and estimated offering expenses payable, was approximately $128.4 million. The Original Private Placement was made in reliance on the exemptions from registration set forth in Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and Rule 506 of Regulation D thereunder and Rule 144A under the Securities Act.

Upon the closing of the Original Private Placement, the Company used $48.8 million of the proceeds to acquire its initial mortgage portfolio through the acquisition of 82% of the equity interests in Little Ajax II, LLC (“Little Ajax II”). Little Ajax II was an affiliated entity that acquired primarily re-performing mortgage loans and a number of non-performing mortgage loans in a series of transactions between December 1, 2013 and July 7, 2014. In September 2014, the Company completed a transaction to acquire the remaining interests in this initial mortgage-related asset portfolio. The transaction initially had Little Ajax II redeem the 82% membership interest of the operating partnership by distributing to the operating partnership 82% of all Little Ajax II loans, participation interests and real property. The operating partnership then purchased for cash the remaining 18% interest in such real estate assets for an aggregate purchase price of approximately $11.4 million. The operating partnership also purchased from Gregory its 5% interest in the 43 loans in which Little Ajax II held a 95% participation interest for approximately $0.2 million.

On December 16, 2014, the Company closed an additional private placement (the “Second Private Placement”), pursuant to which it sold 2,725,326 shares of common stock and 156,000 OP Units. The purchase price per share was $15.00. The net proceeds from the private placement after deducting the placement fee and offering expenses paid by the Company, was approximately $41.2 million. The Company used the proceeds of the Original Private Placement and the Second Private Placement, referred to collectively as the Private Placements, to purchase re-performing and non-performing loans. The Company completed its initial public offering, or IPO, in February 2015 in which the Company and selling stockholders sold an aggregate of 5,276,797 shares of common stock, including shares sold pursuant to exercise of the option to purchase additional shares granted to the underwriters. The Company sold 3,976,464 shares of common stock and selling stockholders sold 1,300,333 shares of common stock, in each case, including shares sold pursuant to exercise of the option to purchase additional shares granted to the underwriters. The Company used the approximately $53.9 million of proceeds (after deducting the underwriting discount but before deducting estimated offering expenses) to acquire additional mortgage loans and mortgage-related assets.

Basis of presentation and use of estimates These interim consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and the notes thereto for the period ended December 31, 2014 included in the Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 26, 2015. Interim financial statements are prepared in accordance with accounting principles generally accepted in the United States (“ U.S. GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Regulation S-X. In the opinion of management, all adjustments, consisting solely of normal recurring accruals considered necessary for the fair presentation of financial statements for the interim period presented, have been included. The current period’s results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2015. The consolidated financial statements have been prepared in accordance with U.S. GAAP, as contained within the Accounting Standards Codification (“ASC”) of the Financial Accounting Standards Board (“FASB”) and the rules and regulations of the SEC, as applied to interim financial statements. Comparative income statement periods have been omitted as the Company had no operations prior to July 8, 2014. All controlled subsidiaries are included in the consolidated financial statements and all intercompany accounts and transactions have been eliminated in consolidation. The operating partnership is a majority owned partnership that has a non-controlling ownership interest that is included in non-controlling interests on the consolidated balance sheet. As of June 30, 2015, the Company owned 96.1% of the outstanding OP Units and the remaining 3.9% of the OP Units were owned by an unaffiliated holder. The Company’s 19.8% investment in the Manager is accounted for using the equity method because it exercises significant influence on the operations of the Manager through common officers and directors. There is no traded or quoted price for the interests in the Manager since it is privately held. The preparation of consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. The Company considers significant estimates to include expected cash flows from mortgage loans and fair value measurements.
