ORGANIZATION AND OPERATIONS	ORGANIZATION AND OPERATIONS CIM Commercial Trust Corporation (“CIM Commercial” or the “Company”) or together with its wholly-owned subsidiaries (which, together with CIM Commercial, may be referred to as “we,” “us” or “our”) primarily invests in, owns, and operates Class A and creative office investments in vibrant and improving urban communities throughout the United States. These communities are located in areas that include traditional downtown areas and suburban main streets, which have high barriers to entry, high population density, improving demographic trends and a propensity for growth. We were originally organized in 1993 as PMC Commercial Trust (“PMC Commercial”), a Texas real estate investment trust. On July 8, 2013, PMC Commercial entered into a merger agreement (the “Merger Agreement”) with CIM Urban REIT, LLC (“CIM REIT”), an affiliate of CIM Group, L.P. ("CIM Group"), and subsidiaries of the respective parties. CIM REIT was a private commercial REIT and was the owner of CIM Urban Partners, L.P. (“CIM Urban”). The transaction (the “Merger”) was completed on March 11, 2014 (the “Acquisition Date”). The Merger was accounted for as a reverse acquisition under the acquisition method of accounting with CIM Urban considered to be the accounting acquirer based upon the terms of the Merger Agreement. Based on the determination that CIM Urban was the accounting acquirer in the transaction, CIM Urban allocated the purchase price to the fair value of PMC Commercial’s assets and liabilities as of the Acquisition Date. On April 28, 2014, PMC Commercial’s charter was amended to increase the authorized shares of stock of PMC Commercial from 100,000,000 to 1,000,000,000 shares (of which 900,000,000 are shares of PMC Commercial common stock and 100,000,000 are shares of PMC Commercial preferred stock) and PMC Commercial changed its state of incorporation from Texas to Maryland by means of a merger of PMC Commercial with and into a newly formed, wholly-owned Maryland corporate subsidiary. Also, on April 28, 2014, PMC Commercial Trust changed its name to CIM Commercial Trust Corporation. Our common stock, $0.001 par value per share (“Common Stock”), is currently traded on the NASDAQ Global Market under the ticker symbol “CMCT.” On April 28, 2014, we filed Articles of Amendment (the “Reverse Split Amendment”) to effectuate a one-for-five reverse stock split of the Common Stock, effective April 29, 2014. Pursuant to the reverse stock split, each five shares of Common Stock issued and outstanding immediately prior to the effective time of the reverse stock split were converted into one share of Common Stock. Fractional shares of Common Stock were not issued as a result of the reverse stock split; instead, holders of pre-split shares of Common Stock who otherwise would have been entitled to receive a fractional share of Common Stock received an amount in cash equal to the product of the fraction of a share multiplied by the closing price of the Common Stock (as adjusted for the one-for-five reverse stock split). In connection with and immediately following the filing of the Reverse Split Amendment, we filed Articles of Amendment to decrease the par value of the Common Stock issued and outstanding to $0.001 per share, effective April 29, 2014, subsequent to the effective time of the Reverse Split Amendment. All per share and outstanding share information has been presented to reflect the reverse stock split. CIM Commercial has qualified and intends to continue to qualify as a real estate investment trust (“REIT”), as defined in the Internal Revenue Code of 1986, as amended.
