ORGANIZATION, BUSINESS OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1—ORGANIZATION, BUSINESS OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES *Organization and Nature of Operations* B. Riley Financial, Inc. (formerly known as Great American Group, Inc.) and its subsidiaries (collectively the “Company”) provide (i) asset disposition, valuation and appraisal and capital advisory services to a wide range of retail, wholesale and industrial clients, as well as lenders, capital providers, private equity investors and professional services firms throughout the United States, Canada, and Europe and (ii) following the Company’s acquisition of B. Riley & Co. Inc. (“BRC”) on June 18, 2014 and MK Capital Advisors, LLC (“MK Capital”) on February 2, 2015, as more fully described below, investment banking, corporate finance, research, wealth management, sales and trading services to corporate, institutional and high net worth clients. With the acquisition of BRC in 2014, the Company now operates in three operating segments: capital market services (“Capital Markets”), auction and liquidation services (“Auction and Liquidation”), and valuation and appraisal services (“Valuation and Appraisal”). In the Capital Markets segment, the Company provides investment banking, corporate finance, research, sales and trading services to corporate, institutional and high net worth clients. In addition, with the acquisition of MK Capital Advisors, LLC (“MK Capital”) in 2015, the Company also provides wealth management services in the Capital Markets segment. In the Auction and Liquidation segment, the Company provides auction and liquidation services to help clients dispose of assets and capital advisory services. Such assets include multi-location retail inventory, wholesale inventory, trade fixtures, machinery and equipment, intellectual property and real property. In the Valuation and Appraisal segment, the Company provides valuation and appraisal services to clients with independent appraisals in connection with asset based loans, acquisitions, divestitures and other business needs. The Company was incorporated in Delaware on May 7, 2009 as a wholly-owned subsidiary of Alternative Asset Management Acquisition Corp. (“AAMAC”). The Company was formed as a “shell company” for the purpose of acquiring Great American Group, LLC (“GAG, LLC”), a California limited liability company. On July 31, 2009, the members of GAG, LLC (the “Great American Members”) contributed all of their membership interests of GAG, LLC to the Company (the “Contribution”) in exchange for 528,000 shares of common stock of the Company and a subordinated unsecured promissory note in an initial principal amount of $60,000 issued in favor of the Great American Members and the phantom equityholders of GAG, LLC (the “Phantom Equityholders”, and together with the Great American Members, the “Contribution Consideration Recipients”) (see Note 8). Concurrently with the Contribution, AAMAC merged with and into AAMAC Merger Sub, Inc. (“Merger Sub”), a subsidiary of the Company (the “Merger” and, together with the Contribution, the “Acquisition”). As a result of the Acquisition, GAG, LLC and AAMAC became wholly-owned subsidiaries of the Company. The Acquisition has been accounted for as a reverse merger accompanied by a recapitalization of the Company. *Reverse Stock Split* On June 3, 2014, the Company completed a 1 for 20 reverse split of its common stock. The reverse split reduced the Company’s then outstanding shares of 30,002,975 to 1,500,107. Fractional shares from the reverse split were paid in cash based on the closing price of the Company’s common stock on June 2, 2014. The share amounts and earnings per share amounts in the Company’s consolidated financial statement have been adjusted as if the reverse split occurred on January 1, 2014. *Private Placement* On June 5, 2014, the Company completed a private placement of 10,289,300 shares of common stock at a purchase price of $5.00 per share (the “Private Placement”). There were fifty-three accredited investors (the “Investors”) that participated in the Private Placement pursuant to the terms and provisions of a securities purchase agreement entered into among the Company and the Investors on May 19, 2014. At the closing of the Private Placement on June 5, 2014, the Company received net proceeds of approximately $51,233. On June 5, 2014, the Company used $30,180 of the net proceeds from the Private Placement to repay long-term debt payable to Andrew Gumaer and Harvey Yellen, the two former Great American Members (as described in Note 8), both of whom were executive officers and directors of the Company at the time of such repayment. The $30,000 principal payment and then outstanding accrued interest of $180 retired the entire $48,759 face amount of the long-term debt at a discount of $18,759. The discount of $18,759 has been recorded as a capital contribution to additional paid in capital. The Company entered into a registration rights agreement (the “Registration Rights Agreement”) with the investors participating in the Private Placement and selling stockholders of BRC. In accordance with the terms of the Registration Rights Agreement, the Company filed a registration statement on Form S-1 with the Securities and Exchange Commission covering the resale of the common stock issued in the Private Placement and acquisition of BRC on September 18, 2014 and the registration statement was declared effective on November 7, 2014. The Company filed a post-effective amendment to such registration statement on April 20, 2015 with the Securities and Exchange Commission to convert such Form S-1 registration statement into a registration statement on Form S-3, which registration statement, as amended, was declared effective on July 2, 2015. *Registration Statement* On April 20, 2015, the Company filed a registration statement on Form S-3 with the Securities and Exchange Commission covering the potential offering of various securities (and securities that may be issuable upon the conversion, exercise or exchange of such securities) with an aggregate initial offering price up to $50,000,000. Such registration statement also covers the resale of the common stock issued and potentially issuable in the acquisition of MK Capital. Such registration statement, as amended, was declared effective on July 2, 2015.
