I M P O R T A N T D I S C L O S U R E S Assets and Equity Under Management Assets Under Management (“AUM”) represents (i)(a) for real assets, the aggregate total gross assets (“GAV”) at fair value, including the shares of such assets owned by joint venture partners and co-investments, of all of CIM’s advised accounts (each an “Account” and collectively, the “Accounts”) or (b) for operating companies, the aggregate GAV less debt, including the shares of such assets owned by joint venture partners and co -investments, of all of the Accounts (not in duplication of the assets described in (i)(a)), plus (ii) the aggregate unfunded commitments of the Accounts, as of June 30, 2017 (“ Report Date”). The GAV is calculated in accordance with U.S. generally accepted accounting principles on a fair value basis (the “Book Value”) and generally represents the investment’s third-party appraised value as of the Report Date, or as of June 30, 2017, as adjusted further by the result of any partial realizations and quarterly valuation adjustments based upon management’s estimate of fair value, in each case through the Report Date other than as described below with respect to CIM REIT. The only investment currently held by CIM REIT consists of shares in CMCT; the Book Value of CIM REIT is determined by assuming the underlying as sets of CMCT are liquidated based upon management’s estimate of fair value. CIM does not presently view the price of CMCT’s publicly-traded shares to be a meaningful indication of the fair value of CIM REIT’s interest in CMCT due to the fact that the publicly-traded shares of CMCT represent less than 3% of the outstanding shares of CMCT and are thinly-traded. Equity Under Management (“EUM”) represents (i) the aggregate net asset value of the Accounts, plus (ii) the aggregate unfunded commitments of the Accounts . The net asset value of each Account is based upon the aggregate amounts that would be distributable (prior to incentive fee allocations) to such Account assuming a “hypothetical liquidation” of the Account on the date of determination, assuming that: (x) investments are sold at their Book Values; (y) debts are paid and other assets are collected; and (z) appropriate adjustments and/or allocations between equity investors are made in accordance with applicable documents, in each case as determined in accordance with applicable accounting guidance. Net Asset Value The estimated Net Asset Value (“NAV”) contained herein is CMCT’s pro forma NAV given effect to certain transactions that have not been completed. Accordingly, the NAV contained herein is different than the estimated NAV described in the S-11 and must not be treated as “Applicable NAV” for purposes of CMCT’s Series A Preferred Stock offering. The determination of estimated NAV involves a number of subjective assumptions, estimates and judgments that may not be accurate or complete. Further, different firms using different property-specific, general real estate, capital markets, economic and other assumptions, estimates and judgments could derive an estimated NAV that could be significantly different from our estimated NAV. Additionally, our estimated NAV does not give effect to changes in value, investment activities, capital activities, indebtedness levels and other various activities occurring after June 30, 2017 that would have an impact on our estimated NAV, other than the sale of assets that were sold or are under contract for sale as of October 24, 2017 (7083 Hollywood Boulevard, 800 North Capitol Street, 370 L’Enfant Promenade, 4200 Scotland Street and 47 E 34th Street) and the $65M of unsecured debt pay down made in August 2017. The estimated NAV per share of $22.28 was calculated by CIM Investment Advisors, LLC, relying in part on appraisals of our re al estate investments and the assets of our lending segment. The table sets forth the material items included in the calculation of our estimated NAV. We engaged various third party appraisal firms to perform appraisals of our real estate investments and the assets of our lending segment as of December 31, 2016. Except for t wo multifamily properties and three office properties that were sold or are under contract for sale as of October 24, 2017, the fair values of our investments in real estate were based on appraisals obtained as of December 31, 2016 plus capex additions, at cost, incurred thereafter. The fair values of our two multifamily properties and three office properties were based on actual proceeds received when the properties were sold, or expected proceeds to be received, based on purchase and sale agreements entered into with unrelated third parties. The fair values of the assets of our lending segment were based on an appraisal obtained as of December 31, 2016 plus loan activity, at cost, incurred thereafter. The December 31, 2016 appraisals were performed in accordance with standards set forth by the American Institute of Certified Public Accountants. Each of our appraisals was prepared by personnel who are subject to and in compliance with the code of professional ethics and the standa rds of professional conduct set forth by the certification programs of the professional appraisal organizations of which they are members.
