Organization Consolidation And Presentation Of Financial Statements [Abstract]

Organization

1. ORGANIZATION

Comstock Holding Companies, Inc., incorporated in 2004 as a Delaware corporation, is a multi-faceted asset management and services company primarily focused in the Washington, D.C. Metropolitan Statistical Area. In 2018, the Company made a strategic decision to transform its operating platform from being primarily focused on developing on-balance sheet, for-sale, homebuilding projects to being focused on commercial and residential asset management and real estate related services. On April 30, 2019 the Company announced the exit from the homebuilding business. The Company now operates through five primarily real estate focused subsidiaries – CDS Asset Management, LC (“CAM”), Comstock Residential Management, LC, Comstock Commercial Management, LC, Park X Management, LC and Comstock Environmental Services, LC (“CES”). The Company’s homebuilding operations are presented in Discontinued Operations (see Note 19 – Discontinued Operations). References in these Consolidated Financial Statements to “Comstock,” “Company”, “we,” “our” and “us” refer to Comstock Holding Companies, Inc. together in each case with our subsidiaries unless the context suggests otherwise.

Liquidity Developments

We finance our Asset management and Real Estate Services operations, capital expenditures, and business acquisitions with internally generated funds, borrowings from our credit facilities and long-term debt. Pursuant to the Master Transfer Agreement (“MTA”), the Company transferred to Comstock Development Services, LC (“CDS”), an entity owned and controlled by the Company’s Chief Executive Officer, its Class A membership interests in Investors X, the entity owning the Company’s residual homebuilding operations in exchange for certain residual cash flows over the next three years (“Investors X”). Refer to Note 13 – Consolidation of Variable Interest Entities for further discussion regarding the accounting related to discontinued operations. The associated debt obligations were also transferred to CDS. See Note 9 in the accompanying Consolidated Financial Statements for more details on our debt and credit facilities.

At December 31, 2019, $5.7 million of our notes payable to affiliates were set to mature prior to the end of 2020. These funds were primarily obtained from entities wholly owned by our Chief Executive Officer, and the Company. On March 19, 2020, the Company entered into a $10 million revolving line of credit agreement with CDS with an initial term of five years. See Note 21 – Subsequent Events for additional information about the transaction.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies and practices used in the preparation of the Consolidated Financial Statements is as follows:

Basis of presentation

The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and include the accounts of the Company and its consolidated subsidiaries. Intercompany balances and transactions have been eliminated. Investments in real estate ventures over which we exercise significant influence, but do not control, are accounted for either at fair value or under the equity method.

When applying principles of consolidation, we begin by determining whether an investee entity is a variable interest entity ("VIE") or a voting interest entity. U.S. GAAP draws a distinction between voting interest entities, which are embodied by common and traditional corporate and certain partnership structures, and VIEs, broadly defined as entities for which control is achieved through means other than voting rights. For voting interest entities, the interest holder with control through majority ownership and majority voting rights consolidates the entity. For VIEs, determination of the "primary beneficiary" dictates the accounting treatment. We identify the primary beneficiary of a VIE as the enterprise having both (i) the power to direct the activities of the VIE that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses or receive benefits of the VIE that could potentially be significant to the VIE. We perform the primary beneficiary analysis as of the inception of our investment and upon the occurrence of a reconsideration event. When we determine we are the primary beneficiary of a VIE, we consolidate the VIE; when we determine we are not the primary beneficiary of the VIE, we account for our investment in the VIE at fair value or under the equity method, based upon an election made at the time of investment.

Our determination of the appropriate accounting method to apply for unconsolidated investments is based on the level of influence we have in the underlying entity. When we have an asset management or property management contract with a real estate limited partnership in which we also hold an ownership interest, the combination of our limited partner interest and the management agreement generally provides us with significant influence over such real estate limited partnership. Accordingly, we account for such investments either at fair value or under the equity method. We eliminate transactions with such subsidiaries to the extent of our ownership in such subsidiaries.

Use of estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates are utilized in the valuation of equity method investments, valuation of deferred tax assets, analysis of goodwill impairment, and valuation of equity-based compensation.

Discontinued Operations

On July 23, 2019 the Company completed the transfer of Investors X subject to the Master Transfer Agreement (“MTA”). For the years ended December 31, 2019 and 2018, we classified revenues, expenses, assets and liabilities related to Investors X into discontinued operations on the Consolidated Balance Sheets, the Consolidated Statement of Operations, and the Consolidated Statements of Cash Flows. See Note 19 – Discontinued Operations.

Cash and cash equivalents

Cash and cash equivalents are comprised of cash and short-term investments with maturities of three months or less when purchased. The carrying amount of cash equivalents approximates fair value due to the short-term maturity of these investments.

Trade Receivables and Concentration of Credit Risk

Trade receivables are recorded at the amount invoiced. We reduce accounts receivable by estimating an allowance for amounts that may become uncollectible in the future. Management determines the estimated allowance for uncollectible amounts based on their judgements in evaluating the aging of the receivables and the financial condition of our clients, which may be dependent on the type of client and the client’s current financial condition.

The Company does significant business with related party entities. Financial instruments that subject the Company to concentrations of credit risk consist primarily of related party receivables. The Company generally does not obtain collateral or other security to support financial instruments subject to credit risk, but monitors the credit standing of related party entities. The Company derives a substantial portion of its revenues from various related party entities; with related party entities accounting for 81% of the Company’s total consolidated revenues in 2019.

See Note 14 – Related Party Transactions for more information.

Investments in real estate ventures

We invest in certain real estate ventures that primarily own and operate real estate in two sectors, land development and commercial office. These investments take the form of equity ownership interests and, based upon investment-specific objectives, have included three to seven year planned investment periods. Our investments in real estate ventures are not redeemable until the disposition of the underlying real estate investment. We have elected to account for these equity method investments using the fair value option.

For investments in real estate ventures reported at fair value, we maintain an investment account that is increased or decreased each reporting period by the difference between the fair value of the investment and the carrying value as of the balance sheet date. These fair value adjustments are reflected as gains or losses on the Consolidated Statements of Operations. The fair value of these investments as of the balance sheet date is generally determined using a Discounted Cash Flow (“DCF”) analysis, based upon unobservable inputs in the fair value hierarchy.

See Note 4, Investments in Real Estate Ventures for additional information on Investments in real estate ventures.

Fixed assets, net

Fixed assets are carried at cost less accumulated depreciation and are depreciated on the straight-line method over their estimated useful lives as follows:

Leasehold improvements		Shorter of asset life or related lease term
Furniture and fixtures		7 years
Office equipment		5 years
Vehicles		3 years
Computer equipment		3 years
Capitalized software		3 years

Leases

Substantially all of our operating leases are related to office space we lease in various buildings for our own use. The terms of these non-cancelable operating leases typically require us to pay rent and a share of operating expenses and real estate taxes, generally with an inflation-based rent increase included. We also lease equipment under both operating and finance lease arrangements. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments (e.g. rent) over the lease term beginning at the commencement date. The Operating lease right-of-use assets are adjusted for lease incentives, deferred rent, and initial direct costs, if incurred. Our leases generally do not include an implicit rate; therefore, we use an incremental borrowing rate based on information available at the lease commencement date in determining the present value of future minimum lease payments. The related lease expense is recognized on a straight-line basis over the lease term.

See Note 6 – Leases for more information

Goodwill and Intangible Assets

Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a business acquisition. Following an acquisition, we perform an analysis to value the acquired company’s tangible and identifiable intangible assets and liabilities. With respect to identifiable intangible assets, we consider backlog, non-compete agreements, client relationships, trade names, patents and other assets. We amortize our intangible assets based on the period over which the contractual or economic benefits of the intangible assets are expected to be realized. We assess the recoverability of the unamortized balance of our intangible assets when indicators of impairment are present based on expected future profitability and undiscounted expected cash flows and their contribution to our overall operations. Should the review indicate that the carrying value is not fully recoverable, the excess of the carrying value over the fair value of the intangible assets would be recognized as an impairment loss.

We perform our annual goodwill impairment review during our fourth quarter as of October 1. In addition, we regularly evaluate whether events and circumstances have occurred that may indicate a potential change in recoverability of goodwill. We perform interim goodwill impairment reviews between our annual reviews if certain events and circumstances have occurred, including a deterioration in general economic conditions, an increased competitive environment, a change in management, key personnel, strategy or customers, significant or unusual changes in market capitalization, negative or declining cash flows, or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods.

When assessing goodwill for impairment, the Company may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is less than it’s carrying amount or elect to bypass such assessment. If it is determined that it is more likely than not that the fair value of a reporting unit is less than it’s carrying value, or the Company elects to bypass such assessment, the Company then determines the fair value of each reporting unit. The estimate of the fair value of each reporting unit is based on a projected discounted cash flow model that includes significant assumptions and estimates including the Company's discount rate, growth rate and future financial performance as well as a market multiple model based upon similar transactions in the market. Assumptions about the discount rate are based on a weighted average cost of capital built up from various interest rate components applicable to the Company. Assumptions about the growth rate and future financial performance of a reporting unit are based on the Company's forecasts, business plans, economic projections and anticipated future cash flows. Market multiples are derived from recent transactions among businesses of a similar size and industry. The fair value of each reporting unit is compared to the carrying amount of the reporting unit. If the carrying value of the reporting unit exceeds the fair value, then an impairment loss is recognized for the difference

Debt Issuance Costs

Costs incurred in connection with the issuance of long-term debt are deferred and amortized as interest expense over the term of the related debt using the effective interest method for term debt and on a straight-line basis for revolving debt. To the extent that debt is outstanding, these amounts are reflected in the Consolidated Balance Sheets as direct deductions of debt and as assets for costs related to revolving debt. See Note 9 for additional information on the Company's long-term debt and related debt issuance costs.

Revenue recognition

The Company’s revenues consist primarily of

•

Asset Management;

•

Property Management;

•

Capital Markets;

•

Leasing;

•

Project & Development Services; and

•

Environmental Remediation

Asset Management

Asset Management primarily provides comprehensive real estate asset management services to the CDS portfolio, representing a series of daily performance obligations delivered over time. Pricing includes a cost-plus management fee or a market-rate fee form of variable consideration. The Company earns whichever is higher. See Note 14 – Related Party Transactions.

The amount of revenue recognized is presented gross for any services provided by our employees, as we control them. This is evidenced by our obligation for their performance and our ability to direct and redirect their work, as well as negotiate the value of such services. In the instances where we do not control third-party services delivered to the client, we report revenues net of the third-party reimbursements. Consistent with the transfer of control for distinct, daily services to the customer, revenue is typically recognized at the end of each period for the fees associated with the services performed.

Property Management

Property Management provides on-site day-to-day management services for owners of office, industrial, retail, multifamily residential and various other types of properties, representing a series of daily performance obligations delivered over time. Pricing is generally in the form of a monthly management fee based upon property-level cash receipts, square footage under management or some other variable metric. Revenues from project management may also include reimbursement of payroll and related costs for personnel providing the services and subcontracted vendor costs. Project management services represent a series of distinct daily services rendered over time. Consistent with the transfer of control for distinct, daily services to the customer, revenue is typically recognized at the end of each period for the fees associated with the services performed.

Capital Markets

We offer clients commercial mortgage and structured financing services. We are compensated for our services via a fee paid upon successful commercial financing from third party lenders. The fee earned is contingent upon the funding of the loan, which represents the transfer of control for services to the customer. Therefore, we typically satisfy our performance obligation at the point in time of the funding of the loan, when there is a present right to payment.

Leasing

We provide strategic advice and execution for owners, investors, and occupiers of real estate in connection with the leasing of office, industrial and retail space. We are compensated for our services in the form of a commission. Our commission is paid upon signing of the lease by the tenant. We satisfy our performance obligation at a point in time; generally, at the time of the contractual event where there is a present right to payment.

Project & Development Services

We provide project and construction management services for owners and occupiers of real estate in connection with the management and leasing of office, industrial and retail space. The fees that we earn are typically variable based upon a percentage of project cost. We are compensated for our services in the form management fees. Project and construction management services represent a series of performance obligations delivered over time and revenue is recognized over time.

Environmental Remediation

We provide environmental remediation services for owners of real estate. Remediation services are generally contracted and performed by Comstock Environmental. We are compensated for our services as well as for the services of subcontractors used to perform remediation services. Fees earned are generally based upon employee time spent as well as a cost-plus arrangement for subcontractors used. Generally, environmental remediation services represent a series of performance obligations delivered over time and revenue is recognized over time.

Contract Costs

Expenses, primarily employee commissions, incurred on leasing and capital markets transactions represent substantially all our incremental costs to obtain revenue contracts. We apply the applicable practical expedient offered by ASC Topic 606 when the amortization period is one year or less and, therefore, recognize these costs as an operating expense as they are incurred.

Stock compensation

As discussed in Note 12, the Company sponsors stock option plans and restricted stock award plans. The Company accounts for its share-based awards pursuant to Accounting Standards Codification (“ASC”) 718, Share Based Payments. ASC 718 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements over the service period based on their fair values at the date of grant. For the year ended December 31, 2019, total stock based compensation cost was $479 thousand of which $474 thousand was charged to expenses within ‘general and administrative’ and ‘Direct costs - real estate services’ in the Consolidated Statement of Operations, and $5 thousand was capitalized to ‘Long-term assets of discontinued operations’. For the year ended December 31, 2018, total stock based compensation cost was $257 thousand of which $234 thousand was charged to expenses within ‘general and administrative’ and ‘Direct costs-real estate services’ in the Consolidated Statement of Operations, and $23 thousand was capitalized to ‘Long-term assets of discontinued operations’.

Income taxes

Income taxes are accounted for under the asset and liability method in accordance with ASC 740, Accounting for Income Taxes. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on the deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We provide a valuation allowance when we consider it “more likely than not” (greater than a 50% probability) that a deferred income tax asset will not be fully recovered. Adjustments to the valuation allowance are a component of the deferred income tax expense or benefit in the Consolidated Statement of Operations.

Recently adopted accounting pronouncements

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” which removes Step 2 from the goodwill impairment test and replaces the qualitative assessment. Impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. Under this revised guidance, failing Step 1 will always result in a goodwill impairment. The amendments in this update should be applied prospectively for annual and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests with measurement dates after January 1, 2017. The Company early adopted this guidance during the fourth quarter of 2018 and the early adoption did not have a material impact on the Company’s Consolidated Financial Statements.

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) 2016-02, “Leases” (“ASU 2016-02”). The core principle of the standard is that a lessee should recognize the assets and liabilities that arise from leases. A lessee should recognize in its statement of financial position a liability to make lease payments (the lease liability) and a right-of-use (“ROU”) asset representing its right to use the underlying asset for the lease term. The FASB subsequently issued ASU 2018-10 and ASU 2018-11 in July 2018, which provide clarifications and improvements to ASU 2016-02. ASU 2018-11 also provides the optional transition method which will allow companies to apply the new lease standard at the adoption date instead of at the earliest comparative period presented. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018 and interim periods within those fiscal years. The Company adopted this standard using the modified retrospective method effective January 1, 2019. As permitted by the guidance, the Company elected to retain the original lease classification and historical accounting for initial direct costs for leases existing prior to the adoption date and did not reassess contracts entered into prior to the adoption date for the existence of a lease. The Company also did not recognize ROU assets and lease liabilities for short-term leases, which are leases in existence as of the adoption date with an original term of twelve months or less. As a result of the adoption of the standard, the Company recognized ROU assets and liabilities of $170 thousand as of the adoption date on its Consolidated Balance Sheet. There was no cumulative effect on beginning retained earnings. The assets and liabilities recognized upon application of the transition provisions were primarily associated with our existing office leases.

Recent Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326), which modifies how companies recognize expected credit losses on financial instruments and other commitments to extend credit held by an entity at each reporting date. Existing GAAP requires an “incurred loss” methodology whereby companies are prohibited from recording an expected loss until it is probable that the loss has been incurred. ASU 2016-13 requires companies to use a methodology that reflects current expected credit losses (“CECL”) and requires consideration of a broad range of reasonable and supportable information to record and report credit loss estimates, even when the CECL is remote. Companies will be required to record the allowance for credit losses and deduct that amount from the basis of the asset. The guidance is effective for the Company for financial statement periods beginning after December 15, 2022, although early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820) – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which removes, adds and modifies certain disclosure requirements for fair value measurements in Topic 820. ASU 2018-13 removes the following disclosure requirements: (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and (ii) the entity’s valuation processes for Level 3 fair value measurements. ASU 2018-13 adds the following disclosure requirements: (i) provide information about the measurement uncertainty of Level 3 fair value measurements as of the reporting date rather than a point in the future, (ii) disclose changes in unrealized gains and losses related to Level 3 measurements for the period included in other comprehensive income, and (iii) disclose for Level 3 measurements the range and weighted average of the significant unobservable inputs and the way it is calculated. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. We do not expect the adoption of this pronouncement to have a material impact on our Consolidated Financial Statements.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in ASC 740, Income Tax and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 will be effective for public business entities for annual reporting periods beginning after December 15, 2020, and interim periods within those periods. Early adoption is permitted. We do not expect the adoption of this pronouncement to have a material impact on our Consolidated Financial Statements.

We have evaluated all other issued and unadopted Accounting Standards Updates and believe the adoption of these standards will not have a material impact on our consolidated statements of operations, comprehensive income, balance sheets, or cash flows

Investors X

The Company has elected to account for the equity method investment in Investors X at fair value. Fair Value is determined using a discounted cash flow model based on expected future cash flows for income and realization events of the underlying asset. Expected future cash flows includes contractually fixed revenues and expenses as well as estimates for future revenues and expenses where contracts do not currently exist.

The fair value of the Company’s investment in Investors X was $9.3 million as of the July 23, 2019 deconsolidation. As of December 31, 2019, the fair value of the Company’s investment in Investors X is $7.2 million. The Company received distributions of $1.5 million during the year ended December 31, 2019 and recognized a loss in fair value of $560 thousand due to lower estimated cash flows from a project in the Investors X portfolio.

The Hartford

The Company has elected to account for the equity method investment in The Hartford at fair value. Fair Value is determined using an income approach and sales comparable approach models.

The fair value of the Company’s investment in the Hartford was $1.2 million as of the investment date of December 30, 2019. The $1.2 million is equal to the cash invested into the Hartford. There were no distributions or changes in fair value as of December 31, 2019.

Leases

6. LEASES

On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases, later codified as Accounting Standards Codification ("ASC") 842 ("ASC 842"), using the modified retrospective method. For periods presented prior to the adoption date, the Company continues to follow its previous policy under ASC 840, Leases.

The determination of whether an arrangement contains a lease and the classification of a lease, if applicable, is made at lease commencement, at which time the Company also measures and recognizes an ROU asset, representing the Company’s right to use the underlying asset, and a lease liability, representing the Company’s obligation to make lease payments under the terms of the arrangement. For the purposes of recognizing ROU assets and lease liabilities associated with the Company’s leases, the Company has elected the practical expedient to not recognize a ROU asset or lease liability for short-term leases, which are leases with a term of twelve months or less. The lease term is defined as the noncancelable portion of the lease term plus any periods covered by an option to extend the lease if it is reasonably certain that the option will be exercised.

ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The rates implicit within the Company's leases are generally not determinable; therefore, the Company's incremental borrowing rate of 6.5% is used to determine the present value of lease payments. The determination of the Company’s incremental borrowing rate requires judgment. The incremental borrowing rate is determined at lease commencement, or as of January 1, 2019 for operating leases in existence upon adoption of ASC 842.

The Company has operating leases for its office facilities as well as for office equipment. The Company's leases have remaining terms of less than one year to 3 years. The leases can contain various renewal and termination options. The period which is subject to an option to extend the lease is included in the lease term if it is reasonably certain that the option will be exercised. The period which is subject to an option to terminate the lease is included if it is reasonably certain that the option will not be exercised. Lease costs related to the Company's operating leases are generally recognized as a single ratable lease cost over the lease term.

Maturities of lease liabilities as of December 31, 2019 are as follows:

	Operating Leases
2020	$	59
2021		54
2022		9
Total lease payments		122
Less: imputed interest		8
Present value of lease liabilities	$	114

As of December 31, 2019, operating lease payments include $108 thousand related to options to extend lease terms that are reasonably certain of being exercised. The Company does not have any lease liabilities which have not yet commenced as of December 31, 2019.

Goodwill and Intangibles

7. GOODWILL AND INTANGIBLES

On July 17, 2017, Comstock Environmental, an entity wholly owned by CDS Capital Management, L.C., a subsidiary of the Company, purchased all of the business assets of Monridge Environmental, LLC for $2.3 million. Comstock Environmental operates in Maryland, Pennsylvania, New Jersey, and Delaware as an environmental services company, providing consulting, remediation, and other environmental services.

Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed, and it is not deductible for income tax purposes. As of the acquisition date, goodwill consisted primarily of synergies resulting from the combination, expected expanded opportunities for growth and production, and savings in corporate overhead costs. As of December 31, 2019 and 2018 the balance of Goodwill was $1.7 million. This Goodwill is reflected within our Real Estate Services segment.

Intangible assets include customer relationships which has an amortization period of four years. During the years ended December 31, 2019 and 2018, $67 thousand of intangible asset amortization was recorded in General and Administrative expense on the Consolidated Statement of Operations.

Secured financing

As of December 31, 2019 and 2018, the Company had two secured loans related to Comstock Environmental. One loan was used to finance the acquisition of Comstock Environmental, and carries a fixed interest rate of 6.5%, and has a maturity date of October 17, 2022. At December 31, 2019 and 2018, this financing had an outstanding balance of $667 thousand and $874 thousand, respectively. Comstock Environmental has an additional secured loan with an outstanding balance of $27 thousand as of December 31, 2019 and an outstanding balance of $34 thousand as of December 31, 2018 to fund the purchase of an asset used in the business. This financing is secured by the assets of Comstock Environmental and is guaranteed by our Chief Executive Officer.

During 2018, the Company opened a secured line of credit with a maximum capacity of $0.2 million, which was paid in full during the three months ended March 31, 2019. Interest charged on this line of credit was based on the prime rate plus 2.50%. As of December 31, 2018, there was $13 thousand of principal and interest outstanding on this line of credit, and the interest rate was 6.75%.

Unsecured financing

As of December 31, 2019 and December 31, 2018, the Company had one unsecured seller-financed promissory note with an outstanding balance of $595 thousand.

Notes payable to affiliate—unsecured

On October 17, 2014, the Company entered into an unsecured promissory note with Comstock Growth Fund (“CGF”) whereby CGF made a loan to the Company in the initial principal amount of $10.0 million and a maximum amount available for borrowing of up to $20.0 million with a three-year term. On December 18, 2014, the loan agreement was amended and restated to provide for a maximum capacity of $25 million. On May 23, 2018, the Company entered into a Membership Interest Exchange and Subscription Agreement (the “Membership Exchange Agreement”), together with a revised promissory note agreement, in which a note (“CGF Note”) with an outstanding principal and accrued interest balance of $7.7 million was exchanged for 1,482,300 shares of the Company’s Series C Non-Convertible Preferred Stock, par value $0.01 per share and a stated liquidation value of $5.00 per share (the “Series C Preferred Stock”), issued by the Company to CDS. The Company exchanged the preferred equity for 91.5% of CDS membership interest in the Comstock Growth Fund promissory note. Concurrently, the face amount of the CGF Note was reduced to $5.7 million as of the Effective Date. The loan bears interest at a fixed rate of 10% per annum. Interest payments will be made monthly in arrears. The Company is the administrative manager of CGF but does not own any membership interests. The Company had approximately $5.7 million of outstanding borrowings and accrued interest under the CGF loan, net of discounts, as of December 31, 2019 and 2018, respectively. The maturity date for the CGF Note is April 16, 2020. On April 13, 2020 the Company retired the CGF Note.

The Company leases office facilities under various non-cancelable operating leases. The leases contain various renewal options. See Note 6 for further discussion of the Company's operating lease commitments.

Currently, and from time to time, the Company is involved in litigation incidental to the conduct of its business. In accordance with GAAP, the Company records a provision for a liability when it is both probable that a liability has been incurred and the amount can be reasonably estimated. While it is reasonably possible that an unfavorable outcome may occur as a result of one or more of the Company’s current litigation matters, at this time management has concluded that the resolutions of these matters are not expected to have a material effect on the Company's consolidated financial position, future results of operations or liquidity. Legal defense costs are expensed as incurred.

Fair Value Disclosures

11. FAIR VALUE DISCLOSURES

We measure certain assets and liabilities in accordance with ASC 820, Fair Value Measurements and Disclosures, which defines fair value as the price that would be received for an asset, or paid to transfer a liability, in an orderly transaction between market participants on the measurement date. In addition, it establishes a framework for measuring fair value according to the following three-tier fair value hierarchy:

•

Level 1 - Quoted prices for identical assets or liabilities in active markets accessible as of the measurement date;

•

Level 2 - Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

•

Level 3 - Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Financial Instruments

The carrying amounts reported in the Consolidated Balance Sheets for cash and cash equivalents, accounts receivable, and accounts payable and accrued liabilities are reasonable estimates of their fair values based on their short maturities. The fair value of fixed and floating rate debt is based on unobservable inputs (Level 3 inputs). The fair value of the fixed and floating rate debt was estimated using a discounted cash flow analysis on the blended borrower rates currently available to the Company for loans with similar terms.

The following table summarizes the fair value of fixed and floating rate debt and the corresponding carrying value of fixed and floating rate debt as of:

2019

2018

Carrying amount

Fair value

Fair value estimates are made at a specific point in time, based on relevant market information about the financial instruments. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore, cannot be determined with precision. Changes in assumptions, such as an acceleration of amounts due and payable, could significantly affect the estimates.

In connection with the CGF I & II conversions discussed in Note 9 – Debt and Note 14 – Related Party Transactions, we issued 2,220,690 shares of Series C Non-Convertible Preferred Stock with a liquidation preference of $5.00 per share. The Series C Preferred Stock has a discretionary dividend feature. The Company recorded these shares based on the fair value calculation on the effective date of the agreement. The Company used various assumptions and level 3 inputs such as current market condition and financial position in calculating the fair value of the Series C Preferred Stock by back solving from the Company’s equity value using the option pricing and the probability-weighted expected return models, adjusted for marketability of the Series C Preferred Stock.

Investments in Real Estate Ventures at Fair Value

We report our two investments in real estate ventures at fair value. For such investments, we increase or decrease our investment each reporting period by the change in the fair value and we report these fair value adjustments in the Consolidated Statements of Operations.

For our investments in real estate ventures at fair value, we estimate the fair value using the level 3 Income Approach or a sales comparable approach to determine a fair value. Critical inputs to fair value estimates include various level 3 inputs such as valuations of the underlying real estate assets and borrowings, which incorporate investment-specific assumptions such as discount rates, capitalization rates, rental and expense growth rates, and asset-specific market borrowing rates. As of December 31, 2019, investments in the real estate ventures at fair value was approximately $8.4 million.

Non-Recurring Fair Value Measurements

The Company may also value its non-financial assets and liabilities, including items such as long-lived assets, at fair value on a non-recurring basis if it is determined that impairment has occurred. Such fair value measurements use significant unobservable inputs and are classified as Level 3.

- Definition

Restricted Stock, Stock Options and Other Stock Plans

12. RESTRICTED STOCK, STOCK OPTIONS AND OTHER STOCK PLANS

On December 14, 2004, the Company adopted the 2004 Long-Term Compensation Plan (the “2004 Plan”). On February 12, 2019 the Company approved the 2019 Omnibus Incentive Plan (the “2019 Plan”) which replaced the 2004 Plan. The 2019 Plan provides for the issuance of stock options, stock appreciation rights, or SARs, restricted stock, deferred stock, dividend equivalents, bonus stock and awards in lieu of cash compensation, other stock-based awards and performance awards. Any shares issued under the Plan typically vest over periods of four years. Stock options issued under the plan expire 10 years from the date they are granted.

The 2019 Plan authorized 2.5 million shares of our Class A Common Stock subject to adjustment for forfeitures and tax withholdings. As of December 31, 2019 and 2018, there were 2.1 million and 0.06 million shares, respectively, available for issuance under the 2019 Plan and 2004 Plan, respectively.

The fair value of each option award is calculated on the date of grant using the Black-Scholes option pricing model and certain subjective assumptions. Expected volatilities are calculated based on our historical trading activities. We recognize forfeitures as they occur. The risk-free rate for the periods is based on the U.S. Treasury rates in effect at the time of grant. The expected term of options is based on the Company’s historical experience.

The following table summarizes the assumptions used to calculate the fair value of options during 2019 and 2018.

Consolidation of Variable Interest Entities

13. CONSOLIDATION OF VARIABLE INTEREST ENTITIES

Consolidated Real Estate Inventories in assets of discontinued operations

Included within the Company’s assets of discontinued operations are real estate entities at December 31, 2018 that were determined to be VIEs. These entities have been established to own and operate real estate property and were deemed VIEs primarily based on the fact that the equity investment at risk is not sufficient to permit the entities to finance their activities without additional financial support. The Company determined that it was the primary beneficiary of these VIEs as a result of the Company’s majority voting rights and complete operational control of these entities.

On January 1, 2019 the Company evaluated Investors X and determined that the equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support and the Company was the primary beneficiary of the VIE as a result of its complete operational control of the activities that most significantly impact the economic performance and its obligation to absorb losses or receive benefits. As a result of the MTA, the Company determined that Investors X is considered held for sale effective April 30, 2019 and Investors X activities have been reclassified to discontinued operations in the accompanying Consolidated Financial Statements.

On July 23, 2019, the Investors X operating agreement was amended to clarify certain definitions resulting in Investors X no longer being considered a VIE of the Company. Therefore, the assets and liabilities of Investors X were deconsolidated effective July 23, 2019 in the Consolidated Balance Sheets of the Company.

Income Tax Disclosure [Abstract]

Income Taxes

18. INCOME TAXES

During the year ended December 31, 2019, the Company recognized income tax expense of $2 thousand from continuing operations and the effective tax rate was (0.29)%. During the year ended December 31, 2018, the Company recognized income tax benefit of $1.1 million and the effective tax rate was (21.54)%.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company recorded valuation allowances for certain tax attributes and other deferred tax assets. At this time, sufficient uncertainty exists regarding the future realization of these deferred tax assets through future taxable income. If, in the future, the Company believes that it is more likely than not that these deferred tax benefits will be realized, the valuation allowances will be reversed. With a full valuation allowance, any change in the deferred tax asset or liability is fully offset by a corresponding change in the valuation allowance.

The Company currently has approximately $145 million in Net Operating Losses (“NOLs), which is based on current statutory tax rates, including the lower corporate tax rate enacted by the Tax Act. If unused, these NOLs will begin expiring in 2027. Under Code Section 382 (“Section 382”) rules, if a change of ownership is triggered, the Company’s NOL assets and possibly certain other deferred tax assets may be impaired. We estimate that as of December 31, 2019, the three-year cumulative shift in ownership of the Company’s stock has not triggered an impairment of our NOL asset. However, if an ownership change were to occur, the Section 382 limitation would not be expected to materially impact the Company’s financial position or results of operations as of December 31, 2019, because the Company has recorded a full valuation allowance on substantially all of its net deferred tax assets.

The Company’s ability to use its NOLs (and in certain circumstances, future built-in losses and depreciation deductions) can be negatively affected if there is an “ownership change” as defined under Section 382. In general, an ownership change occurs whenever there is a shift in ownership by more than 50 percentage points by one or more 5% stockholders over a specified time period (generally three years). Given Section 382’s broad definition, an ownership change could be the unintended consequence of otherwise normal market trading in the Company’s stock that is outside of the Company’s control. In an effort to preserve the availability of these NOLs, Comstock adopted a Section 382 rights agreement, which expired in May 2014. In June 2015, at the 2015 Annual Meeting of Stockholders, the Company’s stockholders approved a new Internal Revenue Code Section 382 Rights Agreement (the “Rights Agreement”) to protect stockholder value. The Rights Agreement expires on March 27, 2025. The Rights Agreement was adopted to reduce the likelihood of such an unintended “ownership change”, thus preserving the value of these tax benefits. Similar plans have been adopted by a number of companies holding similar significant tax assets over the past several years.

The Company has not recorded any accruals related to uncertain tax positions as of December 31, 2019 and 2018, respectively. We file U.S. and state income tax returns in jurisdictions with varying statutes of limitations. The 2016 through 2018 tax years remain subject to examination by federal and most state tax authorities. The income tax provision for continuing operations consists of the following as of December 31:

	2019			2018
Deferred:
Federal	$	178		$	2
State		32			—
		210			2
Valuation allowance		(208	)		(1,064	)
Total income tax expense (benefit)	$	2		$	(1,062	)

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Components of the Company’s deferred tax assets and liabilities at December 31, 2019 and 2018 are as follows:

On March 19, 2020, the Company entered into a Revolving Capital Line of Credit Agreement (the “Loan Documents”) with CDS, pursuant to which the Company secured a capital line of credit (the “Loan”) in the amount of $10 million. Under the terms of the Loan Documents, the Loan provides for an initial variable interest rate of the WSJ Prime Rate plus 1.00% per annum on advances made under the Loan, payable monthly in arrears. The five-year term facility allows for interim draws that carry a maturity date of twelve months from the initial date of the disbursement unless a longer initial term is agreed to by the Lender. On March 27, 2020, the Company drew $5.5 million on the Loan and on April 13, 2020 the Company retired the CGF Note.

COVID-19

In December 2019, COVID-19 surfaced in Wuhan, China. Through March 2020, the spread of this virus and government responses is causing business disruption and is adversely affecting many, including the travel, leisure and hospitality industries and with respect to companies that have significant operations or supply chains in China. The spread of COVID-19 has also caused significant volatility in U.S. and international debt and equity markets, which can negatively impact consumer confidence. There is significant uncertainty around the breadth and duration of business disruptions related to COVID-19, as well as its impact on the U.S. economy and consumer confidence. The Company is taking all necessary steps to keep our business premises, customer properties, vendors and employees in a safe environment and are constantly monitoring the impact of COVID – 19. As discussed in Note 2, the Company derives a substantial portion of its revenues from various related party entities associated with real estate properties. The extent to which COVID-19 impacts our results and the results of the properties we manage will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions taken to contain it or treat its impact. While we have not seen a significant impact to our results from COVID-19 to date, if the virus continues to cause significant negative impacts to economic conditions or consumer confidence, our revenues including our property management revenues, recoverability of assets including trade receivables, related party receivables, goodwill and our fair value investment in Investors X, results of operations, financial condition and liquidity could be adversely impacted.

Cares Act

On March 27, 2020, the United States enacted the Coronavirus Aid, Relief and Economic Security Act (CARES Act). The Cares Act is an emergency economic stimulus package that includes spending and tax breaks to strengthen the United States economy and fund a nationwide effort to curtail the effect of COVID-19. While the CARES Act provides sweeping tax changes in response to the COVID-19 pandemic, some of the more significant provisions which are expected to impact the Company’s financial statements include removal of certain limitations on utilization of net operating losses, increasing the loss carryback period for certain losses to five years, and increasing the ability to deduct interest expense, as well as amending certain provisions of the previously enacted Tax Cuts and Jobs Act. Due to the recent enactment of the CARES Act, the Company is still evaluating the impact, if any, that the CARES Act will have on its financial position, results of operations or cash flows.

Accounting Changes And Error Corrections [Abstract]

Revision of Prior Period Financial Statements

22. REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS

In connection with the preparation of the Company’s 2019 consolidated financial statements, the Company identified errors in its historical financial statements relating to how the Company accounted for debt discounts and how the Company accounted for reimbursement of salaries and other salary related costs. Specifically, the Company incorrectly accounted for debt discount that should have been fully amortized at the end of the initial three-year term of the CGF Note in October 2017. In addition, in 2018 and the interim periods in 2019, the Company previously reported the reimbursement of salary costs from its property management agreements on a net basis, although the Company was required to account for these payroll related reimbursements on a gross basis. The correction of these non-cash errors had no effect on the reported operating income (loss) or total cash flows from operations, investing, or financing of the Company.

The Company evaluated the errors and, based on an analysis of quantitative and qualitative factors, determined that the related impact was not material to the Company’s consolidated financial statements for any prior period.

All financial statements and footnotes presented herein have been adjusted to reflect the revisions below.
