1. ORGANIZATION AND OPERATIONS

CIM Commercial Trust Corporation (“CIM Commercial” or the “Company”), a Maryland corporation and real estate investment trust (“REIT”), or together with its wholly-owned subsidiaries (“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” or “CIM”), 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”). As a result of the Merger and related transactions, CIM Urban became our wholly-owned subsidiary.

Our common stock, $0.001 par value per share (“Common Stock”), is currently traded on the NASDAQ Global Market under the ticker symbol “CMCT.” We have authorized for issuance 900,000,000 shares of common stock and 100,000,000 shares of preferred stock.

CIM Commercial has qualified and intends to continue to qualify as a REIT, as defined in the Internal Revenue Code of 1986, as amended.

2. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

For more information regarding our significant accounting policies and estimates, please refer to “Basis of Presentation and Summary of Significant Accounting Policies” contained in Note 3 to our consolidated financial statements for the year ended December 31, 2016, included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 16, 2017.

Interim Financial Information—The accompanying interim consolidated financial statements of CIM Commercial have been prepared by our management in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Certain information and note disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The accompanying financial information reflects all adjustments which are, in the opinion of our management, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. Our accompanying interim consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto, included in our Annual Report on Form 10-K filed with the SEC on March 16, 2017.

Principles of Consolidation—The consolidated financial statements include the accounts of CIM Commercial and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Investments in Real Estate—Real estate acquisitions are recorded at cost as of the acquisition date. Costs related to the acquisition of properties are expensed as incurred. Investments in real estate are stated at depreciated cost. Depreciation and amortization are recorded on a straight line basis over the estimated useful lives as follows:

A-8

CIM COMMERCIAL TRUST CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements as of September 30, 2017 and December 31, 2016, and

for the Three and Nine Months Ended September 30, 2017 and 2016 (Unaudited)

Improvements and replacements are capitalized when they extend the useful life, increase capacity, or improve the efficiency of the asset. Ordinary repairs and maintenance are expensed as incurred.

Investments in real estate are evaluated for impairment on a quarterly basis or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount to the future net cash flows, undiscounted and without interest, expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. The estimated fair value of the asset group identified for step two of the impairment testing under GAAP is based on either the income approach with market discount rate, terminal capitalization rate and rental rate assumptions being most critical, or on the sales comparison approach to similar properties. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell. We recognized no impairment of long-lived assets during each of the three months ended September 30, 2017 and 2016, respectively, and $13,100,000 and $0 impairment of long-lived assets during the nine months ended September 30, 2017 and 2016, respectively (Note 3).

Derivative Financial Instruments—As part of our risk management and operational strategies, from time to time, we may enter into derivative contracts with various counterparties. All derivatives are recognized on the balance sheet at their estimated fair value. On the date that we enter into a derivative contract, we designate the derivative as a fair value hedge, a cash flow hedge, a foreign currency fair value or cash flow hedge, a hedge of a net investment in a foreign operation, or a trading or non-hedging instrument.

Changes in the estimated fair value of a derivative that is highly effective and that is designated and qualifies as a cash flow hedge, to the extent that the hedge is effective, are initially recorded in other comprehensive income (“OCI”), and are subsequently reclassified into earnings as a component of interest expense when the variability of cash flows of the hedged transaction affects earnings (e.g., when periodic settlements of a variable-rate asset or liability are recorded in earnings). Any hedge ineffectiveness (which represents the amount by which the changes in the estimated fair value of the derivative differ from the variability in the cash flows of the forecasted transaction) is recognized in current-period earnings as a component of interest expense. When an interest rate swap designated as a cash flow hedge no longer qualifies for hedge accounting, we recognize changes in estimated fair value of the hedge previously deferred to accumulated other comprehensive income (“AOCI”), along with any changes in estimated fair value occurring thereafter, through earnings. We classify cash flows from interest rate swap agreements as net cash provided from operating activities on the consolidated statements of cash flows as our accounting policy is to present the cash flows from the hedging instruments in the same category in the consolidated statements of cash flows as the category for the cash flows from the hedged items. See Note 13 for disclosures about our derivative financial instruments and hedging activities.

Loans Receivable—Our loans receivable included in other assets are carried at their unamortized principal balance less unamortized acquisition discounts and premiums, retained loan discounts and loan loss reserves. For loans originated under the Small Business Administration’s (“SBA”) 7(a) Guaranteed Loan Program (“SBA 7(a) Program”), we sell the portion of the loan that is guaranteed by the SBA. Upon sale of the SBA guaranteed portion of the loans, which are accounted for as sales, the unguaranteed portion of the loan retained by us is valued on a fair value basis and a discount (the “Retained Loan Discount”) is recorded as a reduction in basis of the retained portion of the loan.

At the Acquisition Date, the carrying value of our loans was adjusted to estimated fair market value and acquisition discounts of $33,907,000 were recorded, which are being accreted to interest and other income using the effective interest method. We sold substantially all of our commercial mortgage loans with unamortized acquisition discounts of $15,951,000 to

CIM COMMERCIAL TRUST CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements as of September 30, 2017 and December 31, 2016, and

an unrelated third party in December 2015 (Note 7). Acquisition discounts of $1,455,000 remained as of September 30, 2017, which have not yet been accreted to income.

A loan receivable is generally classified as non-accrual (a “Non-Accrual Loan”) if (i) it is past due as to payment of principal or interest for a period of 60 days or more, (ii) any portion of the loan is classified as doubtful or is charged-off or (iii) the repayment in full of the principal and/or interest is in doubt. Generally, loans are charged-off when management determines that we will be unable to collect any remaining amounts due under the loan agreement, either through liquidation of collateral or other means. Interest income, included in interest and other income or discontinued operations, on a Non-Accrual Loan is recognized on either the cash basis or the cost recovery basis.

On a quarterly basis, and more frequently if indicators exist, we evaluate the collectability of our loans receivable. Our evaluation of collectability involves judgment, estimates, and a review of the ability of the borrower to make principal and interest payments, the underlying collateral and the borrowers’ business models and future operations in accordance with Accounting Standards Codification (“ASC”) 450-20, Contingencies—Loss Contingencies, and ASC 310-10, Receivables. For the three and nine months ended September 30, 2017, we recorded a net impairment of $137,000 and $149,000 on our loans receivable, respectively. For the three and nine months ended September 30, 2016, we recorded a net recovery of $3,000 and $239,000 on our loans receivable, respectively. We establish a general loan loss reserve when available information indicates that it is probable a loss has occurred based on the carrying value of the portfolio and the amount of the loss can be reasonably estimated. Significant judgment is required in determining the general loan loss reserve, including estimates of the likelihood of default and the estimated fair value of the collateral. The general loan loss reserve includes those loans, which may have negative characteristics which have not yet become known to us. In addition to the reserves established on loans not considered impaired that have been evaluated under a specific evaluation, we establish the general loan loss reserve using a consistent methodology to determine a loss percentage to be applied to loan balances. These loss percentages are based on many factors, primarily cumulative and recent loss history and general economic conditions.

Deferred Rent Receivable and Charges—Deferred rent receivable and charges consist of deferred rent, deferred leasing costs, deferred offering costs (Note 11) and other deferred costs. Deferred rent receivable is $52,905,000 and $64,010,000 at September 30, 2017 and December 31, 2016, respectively. Deferred leasing costs, which represent lease commissions and other direct costs associated with the acquisition of tenants, are capitalized and amortized on a straight-line basis over the terms of the related leases. Deferred leasing costs of $52,860,000 and $76,063,000 are presented net of accumulated amortization of $23,294,000 and $25,914,000 at September 30, 2017 and December 31, 2016, respectively. Deferred offering costs represent direct costs incurred in connection with our offering of Units (as defined in Note 11), excluding costs specifically identifiable to a closing, such as commissions, dealer-manager fees, and other registration fees. For a specific issuance of Units, associated offering costs are reclassified as a reduction of proceeds raised on the issuance date. Offering costs incurred but not directly related to a specifically identifiable closing are deferred. Deferred offering costs are first allocated to each issuance on a pro-rata basis equal to the ratio of Units issued in an issuance to the maximum number of Units that are expected to be issued. Then, the deferred offering costs allocated to such issuance are further allocated to the Series A Preferred Stock (as defined in Note 11) and Warrants (as defined in Note 11) issued in such issuance based on the relative fair value of the instruments on the date of issuance. The deferred offering costs allocated to the Series A Preferred Stock and Warrants are reductions to temporary equity and permanent equity, respectively. Deferred offering costs of $2,973,000 and $2,060,000 related to our offering of Units are included in deferred rent receivable and charges at September 30, 2017 and December 31, 2016, respectively. Other deferred costs are $1,550,000 and $135,000 at September 30, 2017 and December 31, 2016, respectively.

Redeemable Preferred Stock—Beginning on the date of original issuance of any given shares of Series A Preferred Stock (Note 11), the holder of such shares will have the right to require the Company to redeem such shares at a redemption price of 100% of the Stated Value (as defined in Note 11), plus accrued and unpaid dividends, subject to the payment of a redemption fee until the fifth anniversary of such issuance. From and after the fifth anniversary of the date of the original issuance, the holder will have the right to require the Company to redeem such shares at a redemption price of 100% of the Stated Value, plus accrued and unpaid dividends, without a redemption fee, and the Company will have the right (but not the

obligation) to redeem such shares at 100% of the Stated Value, plus accrued and unpaid dividends. The applicable redemption price payable upon redemption of any Series A Preferred Stock will be in cash or, on or after the first anniversary of the issuance of such shares of Series A Preferred Stock to be redeemed, in the Company’s sole discretion, in cash or in equal value through the issuance of shares of Common Stock, based on the volume weighted average price of our Common Stock for the 20 trading days prior to the redemption. Since a holder of Series A Preferred Stock has the right to request redemption of such shares and redemptions prior to the first anniversary are to be paid in cash, we have recorded the activity related to our Series A Preferred Stock in temporary equity. We recorded the activity related to our Warrants (Note 11) in permanent equity. On the first anniversary of the date of original issuance of a particular share of Series A Preferred Stock, we intend to reclassify such share of Series A Preferred Stock from temporary equity to permanent equity because the feature giving rise to temporary equity classification, the requirement to satisfy redemption requests in cash, lapses on the first anniversary date. Proceeds and expenses from the sale of the Units are allocated to the Series A Preferred Stock and Warrants using their relative fair values on the date of issuance.

Noncontrolling Interests—Noncontrolling interests represent the interests in various properties owned by third parties.

Restricted Cash—Our mortgage loan and hotel management agreements provide for depositing cash into restricted accounts reserved for capital expenditures, free rent, tenant improvement and leasing commission obligations. Restricted cash also includes cash required to be segregated in connection with certain of our loans receivable.

Assets Held for Sale and Discontinued Operations—In the ordinary course of business, we may periodically enter into agreements relating to dispositions of investments. Some of these agreements are non-binding because either they do not obligate either party to pursue any transactions until the execution of a definitive agreement or they provide the potential buyer with the ability to terminate without penalty or forfeiture of any material deposit, subject to certain specified contingencies, such as completion of due diligence at the discretion of such buyer. We do not classify assets that are subject to such non-binding agreements as held for sale.

We classify assets as held for sale, if material, when they meet the necessary criteria, which include: a) management commits to and actively embarks upon a plan to sell the assets, b) the assets to be sold are available for immediate sale in their present condition, c) the sale is expected to be completed within one year under terms usual and customary for such sales and d) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. We generally believe that we meet these criteria when the plan for sale has been approved by our board of directors (the “Board of Directors”), there are no known significant contingencies related to the sale and management believes it is probable that the sale will be completed within one year.

Assets held for sale are recorded at the lower of cost or estimated fair value less cost to sell. In addition, if we were to determine that the asset disposal associated with assets held for sale or disposed of represents a strategic shift, the revenues, expenses and net gain (loss) on dispositions would be recorded in discontinued operations for all periods presented through the date of the applicable disposition.

We have assessed the sale of four of our multifamily properties and our agreement to sell our remaining multifamily property (Note 3) in accordance with ASC 205-20, Discontinued Operations. In our assessment, we considered, among other factors, the materiality of the revenue, net operating income, and total assets of our multifamily segment during the three and nine months ended September 30, 2017 and for the years ended December 31, 2016 and 2015. Based on our qualitative and quantitative assessment, we concluded the disposals do not represent a strategic shift that will have a major effect on our operations and financial results and they should not be classified as discontinued operations on our consolidated financial statements.

Consolidation Considerations for Our Investments in Real Estate—ASC 810-10, Consolidation, addresses how a business enterprise should evaluate whether it has a controlling interest in an entity through means other than voting rights that would require the entity to be consolidated. We analyze our investments in real estate in accordance with this accounting

A-11

CIM COMMERCIAL TRUST CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements as of September 30, 2017 and December 31, 2016, and

for the Three and Nine Months Ended September 30, 2017 and 2016 (Unaudited)

standard to determine whether they are variable interest entities, and if so, whether we are the primary beneficiary. Our judgment with respect to our level of influence or control over an entity and whether we are the primary beneficiary of a variable interest entity involves consideration of various factors, including the form of our ownership interest, our voting interest, the size of our investment (including loans), and our ability to participate in major policy-making decisions. Our ability to correctly assess our influence or control over an entity affects the presentation of these investments on our consolidated financial statements.

Use of Estimates—The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Recently Issued Accounting Pronouncements—In January 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which is designed to improve the recognition and measurement of financial instruments through targeted changes to existing GAAP. The ASU requires an entity to: (i) measure equity investments at fair value through net income, with certain exceptions; (ii) present in OCI the changes in instrument-specific credit risk for financial liabilities measured using the fair value option; (iii) present financial assets and financial liabilities by measurement category and form of financial asset; (iv) calculate the fair value of financial instruments for disclosure purposes based on an exit price; and (v) assess a valuation allowance on deferred tax assets related to unrealized losses of available-for-sale debt securities in combination with other deferred tax assets. In addition, the ASU provides an election to subsequently measure certain nonmarketable equity investments at cost less any impairment and adjusted for certain observable price changes. The ASU also requires a qualitative impairment assessment of such equity investments and amends certain fair value disclosure requirements. For public business entities, the ASU is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017. Early adoption by public entities to financial statements that have not yet been issued is permitted only for the provision related to instrument-specific credit risk. We are currently in the process of evaluating the impact of adoption of this new accounting guidance on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which is intended to improve financial reporting about leasing transactions. Under the new guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current GAAP, which requires a lessee to recognize only capital leases on the balance sheet, the new ASU will require a lessee to recognize both types of leases on the balance sheet. The lessor accounting will remain largely unchanged from current GAAP. However, the ASU contains some targeted improvements that are intended to align, where necessary, lessor accounting with the lessee accounting model and with the updated revenue recognition guidance issued in 2014. For public entities, the ASU is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2018.

We are currently conducting an evaluation of the impact of the guidance on our consolidated financial statements. We currently believe that the adoption of the standard will not significantly change the accounting for operating leases on our consolidated balance sheet where we are the lessor, and that such leases will be accounted for in a similar method to existing standards with the underlying leased asset being recognized and reported as a real estate asset. We currently expect that certain non-lease components may need to be accounted for separately from the lease components, with the lease components continuing to be recognized on a straight-line basis over the term of the lease and certain non-lease components (such as certain expense reimbursements) being accounted for under the new revenue recognition guidance in ASU 2014-09. We expect to adopt the guidance on a modified retrospective basis.

for the Three and Nine Months Ended September 30, 2017 and 2016 (Unaudited)

In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which is intended to simplify several aspects of the accounting for share-based payment transactions, including accounting for income taxes, classification of excess tax benefits on the statement of cash flows, forfeitures, minimum statutory tax withholding requirements, and classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. In addition, the ASU eliminated certain guidance in ASC 718, which was indefinitely deferred shortly after the issuance of FASB Statement No. 123 (revised 2004), Share-Based Payment. For public entities, the ASU became effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. The adoption of this guidance did not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity. The amendments in the ASU replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For public entities, the ASU is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2019. Early adoption is permitted for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2018. We are currently in the process of evaluating the impact of adoption of this new accounting guidance on our consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which provides guidance on how certain cash receipts and cash payments are to be presented and classified in the statement of cash flows. For public entities, the ASU is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017. Early adoption is permitted. We are currently in the process of evaluating the impact of adoption of this new accounting guidance on our consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this update do not provide a definition of restricted cash or restricted cash equivalents. For public entities, the ASU is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017. Early adoption is permitted. We are currently in the process of evaluating the impact of adoption of this new accounting guidance on our consolidated financial statements.

In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which make certain technical corrections and improvements to ASU 2014-09. For public entities, the ASU is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017. Early adoption is permitted for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016.

We are currently conducting our evaluation of the impact of the guidance on our consolidated financial statements. Specifically, we have evaluated the impact on the timing of gain recognition for dispositions but currently do not believe there will be a material impact to our consolidated financial statements for dispositions given the Company’s historical disposition transactions. In addition, we currently believe that certain non-lease components of revenue from leases (upon the adoption of ASU 2016-02, on January 1, 2019) and certain ancillary revenue may be impacted by the adoption of ASU 2014-09. We are in the process of evaluating the impact of the standard but currently believe the impact would be limited to the timing and income

statement presentation of revenue and not the total amount of revenue recognized over time. We are still assessing the potential impact to our hotel revenues, but due to the short-term, day-to-day nature of the Company’s hotel revenues, the pattern of revenue recognition is not expected to change materially. The Company plans on adopting the standard on January 1, 2018 using the modified retrospective approach.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations: Clarifying the Definition of a Business, which narrows the definition of a business and provides a framework that gives entities a basis for making reasonable judgments about whether a transaction involves an asset or a business. For public entities, the ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017. Early adoption is permitted under certain circumstances as outlined in the ASU. We are currently in the process of evaluating the impact of adoption of this new accounting guidance on our consolidated financial statements.

In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies the scope of modification accounting. Under the guidance, an entity will not apply modification accounting to a share-based payment award if the award’s fair value, vesting conditions, and classification as an equity or liability instrument remain the same immediately before and after the change. For public entities, the ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017. Early adoption is permitted. We currently do not anticipate the adoption of this new accounting guidance will have a material impact on our consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities, which simplifies and expands the eligible hedging strategies for financial and nonfinancial risks by more closely aligning hedge accounting with a company’s risk management activities, and also simplifies the application of Topic 815, Derivatives and Hedging, through targeted improvements in key practice areas. In addition, the ASU prescribes how hedging results should be presented and requires incremental disclosures. Further, the ASU provides partial relief on the timing of certain aspects of hedge documentation and eliminates the requirement to recognize hedge ineffectiveness separately in earnings in the current period. For public entities, the ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2018. Early adoption is permitted in any interim period after issuance of the ASU for existing hedging relationships on the date of adoption. We are currently in the process of evaluating the impact of adoption of this new accounting guidance on our consolidated financial statements.

Other assets consist of the following:

SBA 7(a) Loans, Subject to Credit Risk—Represents the non-government guaranteed retained portion of loans originated under the SBA 7(a) Program and the government guaranteed portion of loans that have not yet been fully funded or sold.

SBA 7(a) Loans, Subject to Secured Borrowings—Represents the government guaranteed portion of loans which were sold with the proceeds received from the sale reflected as secured borrowings—government guaranteed loans. There is no credit risk associated with these loans since the SBA has guaranteed payment of the principal.

At September 30, 2017 and December 31, 2016, 99.0% and 99.7%, respectively, of our loans subject to credit risk were current with the remainder ($494,000 and $249,000, respectively) greater than 29 days delinquent.

7. DISCONTINUED OPERATIONS

We had reflected the lending segment, which was acquired on the Acquisition Date as disclosed in Note 1, as held for sale commencing in 2014, based on a plan approved by the Board of Directors to sell the lending segment that, when completed, would have resulted in the deconsolidation of the lending segment, which at that time was focused on small business lending in the hospitality industry. In July 2015, to maximize value, we modified our strategy from a strategy of selling the lending segment as a whole to a strategy of soliciting buyers for components of the business, including our commercial mortgage loans and the SBA 7(a) lending platform. This change in the sale methodology resulted in the need to extend the period to complete the sale of the lending segment beyond one year. In connection with our plan, we expensed transaction costs of $14,000 and $34,000 as incurred during the three and nine months ended September 30, 2016, respectively.

On December 17, 2015, pursuant to the modified plan, we sold substantially all of our commercial mortgage loans with a carrying value of $77,121,000 to an unrelated third party and recognized a gain of $5,151,000.  In September 2016, we discontinued our efforts to sell the SBA 7(a) lending platform, and the activities related to the SBA 7(a) lending platform have been reclassified to continuing operations for all periods presented.

On December 29, 2016, we sold our commercial real estate lending subsidiary, which was classified as held for sale and had a carrying value of $27,587,000, which was equal to management’s estimate of fair value, to a fund managed by an affiliate of CIM Group. We did not recognize any gain or loss in connection with the transaction. Management’s estimate of fair value was determined with assistance from an independent third party valuation firm.

The following is the detail of income from operations of assets held for sale classified as discontinued operations on the consolidated statements of operations for the three and nine months ended September 30, 2016:
