Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Operations of the Company	Note 1. Organization and Operations of the Company Greenbacker Renewable Energy Company LLC (the “LLC”), a Delaware limited liability company, formed in December 2012, is an externally managed energy company that acquires and manages income-generating renewable energy and energy efficiency projects, and other energy-related businesses, as well as financing the construction and/or operation of these and sustainable development projects and businesses. The LLC conducts substantially all its operations through its wholly-owned subsidiary, Greenbacker Renewable Energy Corporation (“GREC”). GREC is a Maryland corporation formed in November 2011 and the LLC currently holds all the outstanding shares of capital stock of GREC. GREC Entity HoldCo LLC (“GREC HoldCo”), a wholly-owned subsidiary of GREC, was formed in Delaware, in June 2016. The use of “we,” “us,” “our” and the “company” refers, collectively, to Greenbacker Renewable Energy Company LLC, Greenbacker Renewable Energy Corporation, and GREC Entity Holdco LLC. We are externally managed and advised by the advisor, a renewable energy, energy efficiency and sustainability related project acquisition, consulting and development company that is registered as an investment adviser under the Investment Advisers Act of 1940, as amended (“Advisers Act”). The LLC’s fiscal year end is December 31. Pursuant to an initial Registration Statement filed in December 2011 (File No. 333-178786-01) and second Registration Statement filed in February 2017 (File No. 333-211571), the company offered up to $1,000,000,000 in shares of limited liability company interests, or the shares, including up to $200,000,000 of shares pursuant to the company’s Distribution Reinvestment Plan (the “DRP”). As of March 29, 2019, the company terminated its public offering of the shares as well as its privately offered Class P-A shares. The company accepted subscriptions for its publicly registered shares until March 27, 2019. While the company publicly offered three classes of shares: Class A, C and I, currently the company is only privately offering Class P-I shares on a continuous basis. The share classes had different selling commissions, dealer manager fees and there is an ongoing distribution fee with respect to Class C shares. The company has adopted the DRP pursuant to which a shareholder owning publicly offered share classes may elect to have the full amount of cash distributions reinvested in additional shares. Following the termination of the company’s public offering of shares, the DRP and the share repurchase plan will continue to be available to existing investors. As of June 4, 2019, pursuant to our Registration Statement on Form S-3 ( File No. 333-231960) we are offering a maximum of $10,000,000 in shares of our common stock to our existing stockholders pursuant to the DRP. Each quarter, our advisor, utilizing the services of an independent valuation firm, when necessary, reviews and approves the net asset value for each class of shares, subject to the oversight of the company’s board of directors. The company expects such determination will ordinarily be made within 30 days after each such completed fiscal quarter. To the extent that the net asset value per share on the most recent valuation date increases or decreases, the company will adjust the offering price of the P-I shares to the then net asset value per share. The adjustments to the per share offering price, which will become effective five business days after such determination is published, will ensure that after the effective date of the new offering price, the offering price per share is not above or below net asset value per share as of the most recent valuation date. The purchase price per share to be paid by each investor will be equal to the price that is in effect on the date such investor submits his or her completed subscription agreement. The company’s P-I shares are offered in the primary offering at a price based on the most recent valuation. Five days after the completion of each quarter-end valuation, Class A, C and I shares will be offered pursuant to the DRP at a price equal to the offering price per each class of shares calculated consistently with the method used during the public continuous offering. As of June 30, 2019, the company has made solar, wind, biomass and energy efficiency investments in 28 portfolios, 27 domiciled in the United States and one in Canada, as well as three secured loans in the United States (See Note 3). As of December 31, 2018, the company had made solar, wind and energy efficiency investments in 26 portfolios, 25 domiciled in the United States and one in Canada, as well as one energy efficiency secured loan in the United States.

Accounting Policies [Abstract]
Significant Accounting Policies	Note 2. Significant Accounting Policies Basis of Presentation The company’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), which requires the use of estimates, assumptions and the exercise of subjective judgment as to future uncertainties. Actual results could differ from those estimates, assumptions, and judgments. Significant items subject to such estimates will include determining the fair value of investments, revenue recognition, income tax uncertainties, and other contingencies. The consolidated financial statements of the company include the accounts of the LLC and its consolidated subsidiaries, GREC and GREC HoldCo. All intercompany accounts and transactions have been eliminated. The company’s consolidated financial statements are prepared using the specialized accounting principles of Accounting Standards Codification Topic 946, Financial Services—Investment Companies (“ASC 946”). In accordance with this specialized accounting guidance, the company recognizes and carries all its investments at fair value with changes in fair value recognized in earnings. The company will not apply the consolidation or equity method of accounting to its investments. The company carries its liabilities at amounts payable, net of unamortized premiums or discounts. The company does not currently plan to elect to carry its non-investment liabilities at fair value. Net assets are calculated as the carrying amounts of assets, including the fair value of investments, less the carrying amounts of its liabilities. The financial information associated with the June 30, 2019 consolidated financial statements has been prepared by management and, in the opinion of management, contains all adjustments and eliminations, consisting of only normal recurring adjustments, necessary for a fair presentation in accordance with GAAP. The June 30, 2019 financial information has been reviewed, but not audited by the independent registered public accounting firm and they do not express an opinion thereon. Cash and Cash Equivalents Cash consists of demand deposits at a financial institution. Such deposits may exceed the Federal Deposit Insurance Corporation insurance limits. The company has not experienced any losses in any such accounts. The company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Short-term investments that are cash equivalents are categorized as Level 1 investments, and stated at cost, which approximates fair value. Restricted Cash and Restricted Cash Equivalents Restricted cash consists of cash accounts or letters of credit that are restricted for use on specific projects. The Company did not have any restrictions on cash prior to June 30, 2019. As of June 30,2019, we have one restricted cash account or letter of credit that for funding of a specific to be constructed asset. Foreign Currency Translation The accounting records of the company are maintained in U.S. Dollars. The fair value of investments and other assets and liabilities denominated in non-U.S. currencies are translated into U.S. Dollars using the exchange rate at the end of each reporting period. Amounts related to the purchases and sales of investments, investment income and expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. Net unrealized currency gains and losses arising from valuing foreign currency denominated assets and liabilities at the current exchange rate are reflected as part of net change in unrealized appreciation (depreciation) on translation of assets and liabilities denominated in foreign currencies in the consolidated statements of operations. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities. Valuation of Investments at Fair Value Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures (“ASC Topic 820”) defines fair value, establishes a framework for measuring fair value in accordance with GAAP and expands disclosures about fair value. The company recognizes and accounts for its investments at fair value. The fair value of the investments does not reflect transaction costs that may be incurred upon disposition of the investments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is an exchange price notion under which fair value is the price in an orderly transaction between market participants to sell an asset or transfer a liability in the market in which the reporting entity would transact for the asset or liability. Pre-operational assets are held at cost until they are operational. Therefore, the fair value associated with these assets are essentially cost. The advisor has established procedures to estimate the fair value of its investments which the company’s board of directors has reviewed and approved. The company will use observable market data to estimate the fair value of investments to the extent that such market data is available. In the absence of quoted market prices in active markets, or quoted market prices for similar assets in markets that are not active, the company will use the valuation methodologies described below with unobservable data based on the best available information in the circumstances, which incorporates the company’s assumptions about the factors that a market participant would use to value the asset. For investments for which quoted market prices are not available, which will comprise most of our investment portfolio, fair value will be estimated by using the income or market approach. The income approach assumes that value is created by the expectation of future benefits discounted to a current value and the fair value estimate is the amount an investor would be willing to pay to receive those future benefits. The market approach compares recent comparable transactions to the investment. Adjustments are made for any dissimilarity between the comparable transactions and the investments. These valuation methodologies involve a significant degree of judgment on the part of our advisor. In determining the appropriate fair value of an investment using these approaches, the most significant information and assumptions include, as applicable: available current market data, including relevant and applicable comparable market transactions, applicable market yields and multiples, security covenants, call protection provisions, information rights, the nature and realizable value of any collateral, the investment’s ability to make payments, its earnings and discounted cash flows, the markets in which the project does business, comparisons of financial ratios of peer companies that are public, comparable mergers and acquisitions, the principal market and enterprise values, environmental factors, among other factors. The estimated fair values will not necessarily represent the amounts that may be ultimately realized due to the occurrence or nonoccurrence of future circumstances that cannot be reasonably determined. Because of the inherent uncertainty of the valuation of the investments, the estimate of fair values may differ significantly from the value that would have been used had a broader market for the investments existed. The authoritative accounting guidance prioritizes the use of market-based inputs over entity-specific inputs and establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation. The three levels of valuation hierarchy are defined as follows: Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets. Level 2: Other significant observable inputs that are sourced either directly or indirectly from publications or pricing services, including dealer or broker markets, for identical or comparable assets or liabilities. Generally, these inputs should be widely accepted and public, non-proprietary and sourced from an independent third party. Level 3: Inputs derived from a significant amount of unobservable market data and derived primarily through the use of internal valuation methodologies. In all cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls will be determined based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of an input to the fair value measurement in its entirety requires judgment and considers factors specific to each investment. Calculation of Net Asset Value Net asset value by share class is calculated by subtracting total liabilities for each class from the total carrying amount of all assets for that class, which includes the fair value of investments. Net asset value per share is calculated by dividing net asset value for each class by the total number of outstanding common shares for that class on the reporting date. Earnings (Loss) per Share In accordance with the provisions of ASC Topic 260 — Earnings per Share (“ASC Topic 260”), basic earnings per share is computed by dividing earnings available to common equityholders by the weighted average number of shares outstanding during the period. Other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis. The following information sets forth the computation of the weighted average basic and diluted net increase in net assets attributed to common equityholders per share for the three and six months ended June 30, 2019 and June 30, 2018. For the three For the three For the six For the six Basic and diluted Increase in net assets attributed to common equityholders $ 6,053,520 $ 5,206,196 $ 10,485,742 $ 9,200,260 Weighted average common shares outstanding 43,145,574 27,522,492 41,338,528 25,866,495 Net increase in net assets attributed to common equityholders per share $ 0.14 $ 0.19 $ 0.25 $ 0.36 Revenue Recognition To the extent the company expects to collect such amounts, interest income is recorded on an accrual basis. If there is reason to doubt an ability to collect such interest, interest receivable on loans and debt securities is not accrued for accounting purposes. Original issue discounts, market discounts or market premiums are accreted or amortized using the effective interest method as interest income. Prepayment premiums on loans and debt securities are recorded as interest income when received. Any application, origination or other fees earned by the company in arranging or issuing debt are amortized over the expected term of the loan. Loans are placed on non-accrual status when principal and interest are 90 days or more past due, or when there is a reasonable doubt that principal or interest will be collected. Accrued interest is generally reversed when a loan is placed on non-accrual. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment. Non-accrual loans are generally restored to accrual status when past due and principal and interest is paid and, in management’s judgment, is likely to remain current. Dividend income is recorded (1) on the ex-dividend date for publicly issued securities and (2) when received from private investments. The timing and amount of dividend income is determined on at least a quarterly basis by GREC. This process includes an analysis at the individual SPV level based on cash available from operations and working capital ratios needed for the SPVs daily operations. Dividend income from our privately held, equity investments are recognized when approved. Dividends received from the company’s private investments, which generally reflect net cash flow from operations, are declared, accrued and paid on a quarterly basis at a minimum. Net Realized Gains or Losses and Net Change in Unrealized Appreciation or Depreciation on Investments Realized gains or losses will be measured as the difference between the net proceeds from the sale, repayment, or disposal of an asset and the adjusted cost basis of the asset, without regard to unrealized appreciation or depreciation previously recognized. Net change in unrealized appreciation or depreciation will reflect the change in investment values during the reporting period, including any reversal of previously recorded unrealized appreciation or depreciation, when gains or losses are realized. Payment-in-Kind Interest For loans and debt securities with contractual payment-in-kind interest, if the valuation indicates that such interest is collectible, any interest will be added to the principal balance of such investments and be recorded as income. Distribution Policy Distributions to members, if any, will be authorized and declared by our board of directors quarterly in advance and paid monthly. From time to time, we may also pay interim special distributions in the form of cash or shares, with the approval of our board of directors. Distributions will be made on all classes of shares at the same time. The cash distributions with respect to the Class C shares will be lower than the cash distributions with respect to the company’s other share classes because of the distribution fee associated with the Class C shares, which is allocated specifically to Class C net assets. Amounts distributed to each class are allocated amongst the holders of the shares in such class in proportion to their shares. Distributions declared by our board of directors are recognized as distribution liabilities on the ex-dividend date. Organization and Offering Costs Organization and offering costs (“O&O costs”), other than sales commissions and the dealer manager fee, were initially paid by our advisor and/or dealer manager on behalf of the company. These O&O costs included all costs previously paid or to be paid by the company in connection with its formation and the offering of its shares pursuant to now-terminated Registration Statements on Form S-1 (File No. 333-178786-01 333-211571 The company was obligated to reimburse our advisor for O&O costs that it incurred on behalf of the company, in accordance with the advisory agreement, but only to the extent that the reimbursement would not cause the selling commissions, the dealer manager fee and the other organization and offering expenses borne by the company to exceed 15% of gross offering proceeds as of the date of reimbursement. Total O&O costs related to the terminated Registration Statements amounted to $9.4 million approximately 3.8% of gross offering proceeds raised pursuant to such Registration Statements. The costs incurred by our advisor and/or dealer manager are recognized as a liability of the company to the extent that the company is obligated to reimburse our advisor and/or dealer manager, subject to the 15% of gross offering proceeds limitation described above. When recognized by the company, organizational costs are expensed and offering costs, excluding selling commissions and dealer manager fees, are recognized as a reduction of the proceeds from the offering. The following table provides information regarding the status of O&O costs (in 000’s) as of June 30, 2019 and December 31, 2018: June 30, December 31, Total O&O Costs Incurred by the Advisor and Dealer Manager $ 9,422 $ 9,371 Amounts previously reimbursed to the Advisor/Dealer Manager by the company 9,422 9,106 Amounts payable to Advisor/Dealer Manager by the company ‒‒ 19 Amounts of the contingent liability subject to payment by the company only upon adequate gross offering proceeds being raised ‒‒ 246 Financing Costs Financing costs related to debt liabilities incurred by the company, GREC or any wholly-owned holding company formed specifically to be a credit agreement counterparty are presented on the consolidated statements of assets and liabilities as a direct deduction from the carrying amount of that debt liability. Financing costs are deferred and amortized using the straight-line method over the life of the debt liability. Capital Gains Incentive Allocation and Distribution Pursuant to the terms of the LLC’s amended and restated limited liability company agreement, a capital gains incentive fee will be earned by an affiliate of our advisor on realized gains (net of realized and unrealized losses) since inception from the sale of investments from the company’s portfolio during operations prior to a liquidation of the company. While the terms of the advisory agreement neither include nor contemplate the inclusion of unrealized gains in the calculation of the capital gains incentive fee, the company will include unrealized gains in the calculation of the capital gains incentive distribution pursuant to an interpretation of an American Institute for Certified Public Accountants Technical Practice Aid for investment companies. Even though the advisor is not entitled to an incentive distribution with respect to unrealized gains unless and until such gains are realized, this amount reflects the incentive distribution that would be payable if the company’s entire portfolio was liquidated at its fair value as of the consolidated statements of assets and liabilities date. Thus, on each date that net asset value is calculated, the company calculates for the capital gains incentive distribution by calculating such distribution as if it were due and payable as of the end of such period and reflected as an allocation of equity between common equityholders and special unitholder. As of June 30, 2019, and December 31, 2018, a capital gains incentive distribution allocation in the amounts of $3,233,426 and $1,797,138, respectively, was recorded in the consolidated statements of assets and liabilities as special unitholder’s equity. Deferred Sales Commissions The company defers certain costs, principally sales commissions and related compensation, which are paid to the dealer manager and may be reallowed to financial advisors and broker/dealers in connection with the sale of Class C shares sold with a reduced front-end load sales charge. The costs expected to be incurred at the time of the sale of Class C shares are recorded as a liability on the date of sale and are amortized on a straight-line basis over the period beginning at the time of sale and ending on the date which approximates an expected liquidity event for the company. As of June 30, 2019, and December 31, 2018, the company recorded a liability for deferred sales commissions in the amount of $142,511 and $191,706, respectively. Reclassifications Certain prior year amounts have been reclassified to conform with current year presentation. Derivative Instruments The company may utilize interest rate swaps to modify interest rate characteristics of existing debt obligations to manage interest rate exposure. These are recorded at fair value either as assets or liabilities in the accompanying consolidated statements of assets and liabilities with changes in the fair value of interest rate swaps during the period recognized as either an unrealized gain or loss in the accompanying consolidated statements of operations. The fair value of interest rate swap contracts open as of June 30, 2019 is included on the consolidated schedules of investments by contract. For the six months ended June 30, 2019, the company’s notional exposure to interest rate swap contracts was $95,072,098.

The company’s exposure to credit risk associated with counterparty non-performance is limited to collateral posted and the unrealized gains that are recognized in the consolidated statement of assets and liabilities. The company minimizes counterparty credit risk through credit monitoring procedures and managing margin and collateral requirements, as appropriate. In regard to our investment in the Canadian Northern Lights Portfolio, we have foreign currency risk related to our revenue and operating expenses which are denominated in the Canadian Dollars as opposed to the U.S. Dollars. While we are currently of the opinion that the currency fluctuation between the Canadian and U.S. Dollar will not have a material impact on our operating results, we may in the future hedge this risk using currency swap transactions or other financial instruments if the impact on our results of operations becomes material. Income Taxes The company intends to operate so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code. As such, it will not be subject to any U.S. federal and state income taxes. In any year, it is possible that the company will not meet the qualifying income exception and will not qualify to be treated as a partnership. If the company does not meet the qualifying income exception, the members would then be treated as stockholders in a corporation and the company would become taxable as a corporation for U.S. federal income tax purposes under the Internal Revenue Code. The company would be required to pay income tax at corporate rates on its net taxable income. Distributions to members from the company would constitute dividend income taxable to such members, to the extent of the company’s earnings and profits and the payment of the distributions would not be deductible by the company. The LLC plans to conduct substantially all its operations through its wholly-owned subsidiary, GREC, which is a corporation that is subject to U.S. federal, state and local income taxes. Accordingly, most of its operations will be subject to U.S. federal, state and local income taxes. Income taxes are accounted for under the assets and liabilities method. Deferred tax assets and liabilities are recorded for the estimated future tax consequences attributable to differences between items that are recognized in the consolidated financial statements and tax returns in different years. 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 on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. For income tax benefits to be recognized including uncertain tax benefits, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of the benefit that is more likely than not to be realized upon ultimate settlement. A valuation allowance is established against net deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the net deferred tax assets will not be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Interest and penalties associated with income taxes, if any, will be recognized in general and administrative expense. The company does not consolidate its investments for financial statements. The company accounts for its investments at fair value under the specialized accounting of ASC Topic 946. The tax attributes of the individual investments will be considered and incorporated in the company’s fair value estimates for those investments. The amounts recognized in the consolidated financial statements for unrealized appreciation and depreciation will result in a difference between the consolidated financial statements and the cost basis of the assets for tax purposes. These differences will be recognized as deferred tax assets and liabilities. Generally, the entities that hold the company’s investments will be included in the consolidated tax return of GREC and the differences between the amounts recognized for financial statement purposes and the tax return will be recognized as additional deferred tax assets and liabilities. The company follows the authoritative guidance on accounting for uncertainty in income taxes and concluded it has no material uncertain tax positions to be recognized at this time. The company assessed its tax positions for all open tax years as of June 30, 2019 for all U.S. federal and state tax jurisdictions for the years 2015 through 2018. The results of this assessment are included in the company’s tax provision and deferred tax assets as of June 30, 2019. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement”, which modifies the disclosure requirements on fair value measurements. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (fiscal 2020 for the company). Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. We are currently evaluating the impact of the amendments on our consolidated financial statement disclosures. Since the amendments impact only disclosure requirements, we do not expect the amendments to have an impact on our consolidated financial statements.

Related Party Transactions [Abstract]
Related Party Agreements and Transactions Agreements	Note 5. Related Party Agreements and Transactions Agreements The company has executed advisory and administration agreements with the advisor and Greenbacker Administration, LLC, our administrator, respectively, as well as a dealer manager agreement with the dealer manager, which entitles the advisor, certain affiliates of the advisor, and the dealer manager to specified fees upon the provision of certain services with regard to the offering of the company’s shares and the ongoing management of the company as well as reimbursement of O&O costs incurred by the advisor and the dealer manager on behalf of the company (as discussed in Note 2) and certain other operating costs incurred by the advisor on behalf of the company. As the continuous public offering was terminated on March 29, 2019, the dealer manager will no longer receive any selling commission or dealer manager fees. However, the dealer manager will continue to receive distribution fess on Class C shares until the maximum amount of commissions and dealer manager fees permitted by applicable regulation is reached. The term “Special Unitholder” refers to GREC Advisors, LLC, a Delaware limited liability company, which is a subsidiary of our advisor and “special unit”, refers to the special unit of limited liability company interest in GREC. This entitles the Special Unitholder to an incentive allocation and distribution. The fees and reimbursement obligations are as follows: Type of Compensation and Recipient Determination of Amount Selling Commissions — Dealer Manager Up to 7% of gross offering proceeds from the sale of Class A shares, up to 3% of gross offering proceeds from the sale of Class C shares and up to 6% of gross offering proceeds for the sale of Class P-A shares. No selling commission will be paid with respect to Class I and Class P-I shares or for sales pursuant to the dividend reinvestment plan. All of its selling commissions are expected to be re-allowed to participating broker-dealers. Dealer Manager Fee — Dealer Manager Up to 2.75% of gross offering proceeds from the sale of Class A and C shares, and up to 1.75% of gross offering proceeds from the sale of Class I shares. No dealer manager fee will be paid for sales pursuant to the dividend reinvestment plan. The dealer manager may re-allow a portion of its dealer manager fee to selected broker-dealers. Distribution Fee — Dealer Manager With respect to Class C shares only, the company will pay the dealer manager a distribution fee that accrues daily in an amount equal to 1/365th of 0.80% of the amount of the net asset value for the Class C shares for such day on a continuous basis from year to year. The company will stop paying distribution fees at the earlier of a listing of the Class C shares on a national securities exchange, following the completion of this offering, total underwriting compensation in this offering equals 10% of the gross proceeds from the primary offering or Class C shares are no longer outstanding. The dealer manager may re-allow all or a portion of the distribution fee to participating broker-dealers and servicing broker dealers. Commencing as of June 30, 2016, the company estimates the amount of distribution fees expected to be paid and records that liability at the time of sale. O&O costs — Advisor The company reimburses the advisor for the O&O costs (other than selling commissions and dealer manager fees) it has incurred on the company’s behalf only to the extent that the reimbursement would not cause the selling commissions, dealer manager fee and the other O&O costs borne by the company to exceed 15.0% of the gross offering proceeds as the amount of proceeds increases. From the commencement of the continuous offering through June 30, 2019, approximately 3.8%, or $9.4 million, was charged against gross offering proceeds for O&O costs. Base Management Fees — Advisor The base management fee payable to GCM will be calculated at a monthly rate of 0.167% (2.00% annually) of our gross assets (including amounts borrowed). For services rendered under the advisory agreement, the base management fee will be payable monthly in arrears. The base management fee will be calculated based on the average of the values of our gross assets for each day of the prior month. Base management fees for any partial period will be appropriately pro-rated. The base management fee may be deferred or waived, in whole or part, at the election of the advisor. All or any part of the deferred base management fee not taken as to any period shall be deferred without interest and may be taken in any period prior to the occurrence of a liquidity event as the advisor shall determine in its sole discretion. Incentive Allocation and Distribution — Special Unitholder The incentive distribution to which the Special Unitholder is be entitled to will be calculated and payable quarterly in arrears based on the pre-incentive distribution net investment income for the immediately preceding fiscal quarter. For this purpose, pre-incentive distribution net investment income means interest income, dividend and distribution income from equity investments (excluding that portion of distributions that are treated as return of capital) and any other income (including any other fees, such as commitment, origination, structuring, diligence and consulting fees or other fees that we receive, but excluding any fees for providing managerial assistance) accrued during the fiscal quarter, minus the operating expenses for the fiscal quarter (including the base management fee, expenses payable under the administration agreement with the company’s Administrator, and any interest expense and distributions paid on any issued and outstanding indebtedness and preferred units of limited liability company interest, but excluding the incentive distribution). Pre-incentive distribution net investment income does not include any realized capital gains, realized capital losses, unrealized capital appreciation or depreciation or any accrued income taxes and other taxes including, but not limited to, franchise, property, and sales taxes. Pre-incentive distribution net investment income, expressed as a rate of return on the value of the company’s average adjusted capital at the end of the immediately preceding fiscal quarter, will be compared to a “hurdle rate” of 1.75% per fiscal quarter (7.00% annualized). Adjusted capital shall mean: cumulative gross proceeds before sales and commission and dealer fees, generated from sales of the company’s shares and preferred units of limited liability company interests (including the DRP) reduced for distributions to members of proceeds from non-liquidation dispositions of asset and amount paid for share repurchases pursuant to the Share Repurchase Program. Average adjusted capital shall mean: the average value of the adjusted capital for the two most recently completed fiscal quarters. The Special Unitholder shall receive an incentive distribution with respect to the pre-incentive distribution net investment income in each fiscal quarter as follows: ● No incentive distribution in any fiscal quarter in which the pre-incentive distribution net investment income does not exceed the “hurdle rate” of 1.75%; ● 100% of the pre-incentive distribution net investment income with respect to that portion of such pre-incentive distribution net investment income, if any, that exceeds the hurdle but is less than 2.1875% in any fiscal quarter (8.75% annualized with a 7% annualized hurdle rate). The company refers to this portion of the pre-incentive distribution net investment income (which exceeds the hurdle but is less than 2.1875%) as the “catch-up.” The “catch-up” is meant to provide the advisor with 20% of the pre-incentive distribution net investment income as if a hurdle did not apply if the net investment income exceeds 2.1875% in any fiscal quarter; and ● 20% of the amount of the pre-incentive distribution net investment income, if any, that exceeds 2.1875% in any fiscal quarter (8.75% annualized with a 7% annualized hurdle rate) is payable to the Special Unitholder (once the hurdle is reached and the catch-up is achieved, 20% of all pre-incentive distribution investment income thereafter is allocated to the Special Unitholder). Capital Gains Incentive Distribution — Special Unitholder The capital gains incentive distribution will be determined and payable to the Special Unitholder in arrears as of the end of each fiscal quarter (or upon termination of the advisory agreement, as of the termination date) to the Special Unitholder, and will equal 20.0% of the company’s realized capital gains, if any, on a cumulative basis from inception through the end of each fiscal quarter, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any capital gain incentive distributions. Liquidation Incentive Distribution — Special Unitholder The liquidation incentive distribution payable to the Special Unitholder will equal 20.0% of the net proceeds from a liquidation of the company (other than in connection with a listing, as described below) in excess of adjusted capital, as measured immediately prior to liquidation. Adjusted capital shall mean: cumulative gross proceeds generated from sales of shares (including the DRP) reduced for distributions to members of proceeds from non-liquidation dispositions of our assets and amounts paid for share repurchases pursuant to the Share Repurchase Program. In the event of any liquidity event that involves a listing of the company’s shares, or a transaction in which the company’s members receive shares of a company that is listed, on a national securities exchange, the liquidation incentive distribution will equal 20% of the amount, if any, by which the company’s listing value following such liquidity event exceeds the adjusted capital, as calculated immediately prior to such listing (the “listing premium”). Any such listing premium and related liquidation incentive distribution will be determined and payable in arrears 30 days after the commencement of trading following such liquidity event. For the three and six months ended June 30, 2019, the advisor earned $2,035,065 and $3,857,131, respectively, in management fees. The Consolidated Statement of Operations also reflects a $19,969 decrease and a $1,436,288 increase in incentive allocation for the three and six months ended June 30, 2019, respectively, shown as net increase/(decrease) in net assets attributed to special unitholder. For the three and six months ended June 30, 2018, the advisor earned $1,353,001 and $2,518,729, respectively, in management fees. The Consolidated Statement of Operations also reflects a $468,354 and a $958,834 increase in incentive allocation for the three and six months ended June 30, 2018, respectively, shown as net decreases in net assets attributed to special unitholder. As of June 30, 2019, and December 31, 2018, due to advisor on the Consolidated Statements of Assets and Liabilities in the amount of nil and $19,181, respectively, are solely comprised of a payable to the advisor for reimbursable Organization and Offering Costs. For the three and six months ended June 30, 2019, the company paid nil and $231,892, respectively, in dealer manager fees and $375 and $594,247, respectively, in selling commissions to the dealer manager, SC Distributors. For the three and six months ended June 30, 2018, the company paid $243,559 and $424,929, respectively, in dealer manager fees and $776,271 and $1,270,145, respectively, in selling commissions to the dealer manager. These fees and commissions were paid in connection with the sales of the company’s shares to investors and, as such, were recorded against the proceeds from the issuance of shares, prior to the receipt by the company, and thus are not reflected in the company’s Consolidated Statements of Operations. As of June 30, 2019, and December 31, 2018, the advisor owned 23,601 Class A shares. The company entered into secured loans to finance the purchase and installation of energy efficient lighting with LED Funding LLC and Renew AEC One LLC (“AEC Companies”). All loans with LED Funding LLC, an AEC Company, converted to operating leases on the day the energy efficiency upgrades became operational. AEC Companies are considered related parties as the members of these entities own an indirect, non-controlling ownership interest in the company’s advisor. The loans outstanding between the AEC Companies and the company, and the subsequent operating leases, were negotiated at an arm’s length and contain standard terms and conditions that would be included in third party lending agreements including required security and collateral, interest rates based upon risk of the specific loan, and term of the loan. As of June 30, 2019, all loans and operating losses are considered current per their terms.

The LLC Agreement authorizes the board of directors, without approval of any of the members, to increase the number of shares the company is authorized to issue and to classify and reclassify any authorized but unissued class or series of shares into any other class or series of shares having such designations, preferences, right, power and duties as may be specified by the board of directors. The LLC Agreement also authorizes the board of directors, without approval of any of the members, to issue additional shares of any class or series for the consideration and on the terms and conditions established by the board of directors. In addition, the company may also issue additional limited liability company interests that have designations, preferences, right, powers and duties that are different from, and may be senior to, those applicable to the common shares. The Special Unitholder will hold the special unit in the company. Refer to Note 5 for the terms of the special unit. The proceeds related to the shareholder receivable amount of $200,000 presented on the Consolidated Statements of Assets and Liabilities as of June 30, 2019 were subsequently collected on July 1, 2019. Distribution Reinvestment Plan The company adopted the DRP through which the company’s Class A, C and I shareholders may elect to purchase additional shares with distributions from the company rather than receiving the cash distributions. Shares issued pursuant to the DRP will have the same voting rights as shares offered pursuant to the company’s public offering. As of June 30, 2019, and December 31, 2018, $10,000,000 and $50,000,000 in shares were allocated for use in the DRP, respectively. As of December 2018, the purchase price of shares purchased through the DRP will be at a price equal to the net offering price per share, calculated consistently with the methodology used during then continuous public offering. Except for distribution fees on Class C shares issued under the DRP, no dealer manager fees, selling commissions or other sales charges will be paid with respect to shares purchased pursuant to the DRP. At its discretion, the board of directors may amend, suspend, or terminate the DRP. A participant may terminate participation in the DRP by written notice to the plan administrator, received by the plan administrator at least 10 days prior to the distribution payment date. As of June 30, 2019, and December 31, 2018, 2,089,427 and 1,703,374 shares, respectively, were issued under the DRP. Share Repurchase Program During the quarter ended September 30, 2015, the company commenced a share repurchase program, or “share repurchase program”, pursuant to which quarterly share repurchases will be conducted, on up to approximately 5% of the weighted average number of outstanding shares in any 12-month period, to allow members who hold Class A, C, I, P-A (commencing as of April 16, 2018) or P-I shares (commencing as of October 1, 2017) to sell shares back to the company at a price equal to the then current offering price less the selling commissions and dealer manager fees associated with that class of shares. The company is not obligated to repurchase shares and the board of directors may terminate the share repurchase program at its sole discretion. The share repurchase program includes numerous restrictions that will limit a shareholder’s ability to sell shares. Unless the board of directors determines otherwise, the company limits the number of shares to be repurchased during any calendar year to the number of shares the company can repurchase with the proceeds received from the sale of shares under the DRP. At the sole discretion of the board of directors, the company may also use cash on hand, cash available from borrowings and cash from liquidation of investments to repurchase shares. In addition, the company plans to limit repurchases in each fiscal quarter to 1.25% of the weighted average number of shares outstanding in the prior four fiscal quarters. For the six months ended June 30, 2019, the company repurchased 304,469 Class A shares, 1,867 Class C shares, 80,366 Class I shares, and 48,185 Class P-I shares at a total purchase price of $2,635,353, $15,853, $695,925, and $422,135, respectively, pursuant to the company’s share repurchase program. For the six months ended June 30, 2018, the company repurchased 140,037 Class A shares, 4,227 Class C shares, 26,071 Class I and 9,743 Class P-I shares at a total purchase of $1,237,852, $36,240, $230,106 and $85,838, respectively, pursuant to the company’s share repurchase program. For the six months ended June 30, 2019, the average NAV per share for the repurchases in Class A, Class C, Class I and Class P-I were $8.66, $8.49, $8.66 and $8.76, respectively. For the six months ended June 30, 2018, the average NAV per share for the repurchases in Class A, Class C, Class I and Class P-I were, $8.84, $8.57, $8.83 and $8.81, respectively. We have received an order for our repurchase program from the SEC under Rule 102(a) of Regulation M under the Exchange Act. In addition, our repurchase program is substantially similar to repurchase programs for which the SEC has stated it will not recommend enforcement action under Rule 13e-4 and Regulation 14E under the Exchange Act.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The company's consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), which requires the use of estimates, assumptions and the exercise of subjective judgment as to future uncertainties. Actual results could differ from those estimates, assumptions, and judgments. Significant items subject to such estimates will include determining the fair value of investments, revenue recognition, income tax uncertainties, and other contingencies. The consolidated financial statements of the company include the accounts of the LLC and its consolidated subsidiaries, GREC and GREC HoldCo. All intercompany accounts and transactions have been eliminated. The company's consolidated financial statements are prepared using the specialized accounting principles of Accounting Standards Codification Topic 946, Financial Services—Investment Companies ("ASC 946"). In accordance with this specialized accounting guidance, the company recognizes and carries all its investments at fair value with changes in fair value recognized in earnings. The company will not apply the consolidation or equity method of accounting to its investments. The company carries its liabilities at amounts payable, net of unamortized premiums or discounts. The company does not currently plan to elect to carry its non-investment liabilities at fair value. Net assets are calculated as the carrying amounts of assets, including the fair value of investments, less the carrying amounts of its liabilities. The financial information associated with the June 30, 2019 consolidated financial statements has been prepared by management and, in the opinion of management, contains all adjustments and eliminations, consisting of only normal recurring adjustments, necessary for a fair presentation in accordance with GAAP. The June 30, 2019 financial information has been reviewed, but not audited by the independent registered public accounting firm and they do not express an opinion thereon.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash consists of demand deposits at a financial institution. Such deposits may exceed the Federal Deposit Insurance Corporation insurance limits. The company has not experienced any losses in any such accounts. The company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Short-term investments that are cash equivalents are categorized as Level 1 investments, and stated at cost, which approximates fair value.
Restricted Cash and Restricted Cash Equivalents	Restricted Cash and Restricted Cash Equivalents Restricted cash consists of cash accounts or letters of credit that are restricted for use on specific projects. The Company did not have any restrictions on cash prior to June 30, 2019. As of June 30,2019, we have one restricted cash account or letter of credit that for funding of a specific to be constructed asset.
Foreign Currency Translation	Foreign Currency Translation The accounting records of the company are maintained in U.S. Dollars. The fair value of investments and other assets and liabilities denominated in non-U.S. currencies are translated into U.S. Dollars using the exchange rate at the end of each reporting period. Amounts related to the purchases and sales of investments, investment income and expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. Net unrealized currency gains and losses arising from valuing foreign currency denominated assets and liabilities at the current exchange rate are reflected as part of net change in unrealized appreciation (depreciation) on translation of assets and liabilities denominated in foreign currencies in the consolidated statements of operations. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities.
Valuation of Investments at Fair Value	Valuation of Investments at Fair Value Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures ("ASC Topic 820") defines fair value, establishes a framework for measuring fair value in accordance with GAAP and expands disclosures about fair value. The company recognizes and accounts for its investments at fair value. The fair value of the investments does not reflect transaction costs that may be incurred upon disposition of the investments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is an exchange price notion under which fair value is the price in an orderly transaction between market participants to sell an asset or transfer a liability in the market in which the reporting entity would transact for the asset or liability. Pre-operational assets are held at cost until they are operational. Therefore, the fair value associated with these assets are essentially cost. The advisor has established procedures to estimate the fair value of its investments which the company's board of directors has reviewed and approved. The company will use observable market data to estimate the fair value of investments to the extent that such market data is available. In the absence of quoted market prices in active markets, or quoted market prices for similar assets in markets that are not active, the company will use the valuation methodologies described below with unobservable data based on the best available information in the circumstances, which incorporates the company's assumptions about the factors that a market participant would use to value the asset. For investments for which quoted market prices are not available, which will comprise most of our investment portfolio, fair value will be estimated by using the income or market approach. The income approach assumes that value is created by the expectation of future benefits discounted to a current value and the fair value estimate is the amount an investor would be willing to pay to receive those future benefits. The market approach compares recent comparable transactions to the investment. Adjustments are made for any dissimilarity between the comparable transactions and the investments. These valuation methodologies involve a significant degree of judgment on the part of our advisor. In determining the appropriate fair value of an investment using these approaches, the most significant information and assumptions include, as applicable: available current market data, including relevant and applicable comparable market transactions, applicable market yields and multiples, security covenants, call protection provisions, information rights, the nature and realizable value of any collateral, the investment's ability to make payments, its earnings and discounted cash flows, the markets in which the project does business, comparisons of financial ratios of peer companies that are public, comparable mergers and acquisitions, the principal market and enterprise values, environmental factors, among other factors. The estimated fair values will not necessarily represent the amounts that may be ultimately realized due to the occurrence or nonoccurrence of future circumstances that cannot be reasonably determined. Because of the inherent uncertainty of the valuation of the investments, the estimate of fair values may differ significantly from the value that would have been used had a broader market for the investments existed. The authoritative accounting guidance prioritizes the use of market-based inputs over entity-specific inputs and establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation. The three levels of valuation hierarchy are defined as follows: Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets. Level 2: Other significant observable inputs that are sourced either directly or indirectly from publications or pricing services, including dealer or broker markets, for identical or comparable assets or liabilities. Generally, these inputs should be widely accepted and public, non-proprietary and sourced from an independent third party. Level 3: Inputs derived from a significant amount of unobservable market data and derived primarily through the use of internal valuation methodologies. In all cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls will be determined based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of an input to the fair value measurement in its entirety requires judgment and considers factors specific to each investment.
Calculation of Net Asset Value	Calculation of Net Asset Value Net asset value by share class is calculated by subtracting total liabilities for each class from the total carrying amount of all assets for that class, which includes the fair value of investments. Net asset value per share is calculated by dividing net asset value for each class by the total number of outstanding common shares for that class on the reporting date.
Earnings (Loss) per Share	Earnings (Loss) per Share In accordance with the provisions of ASC Topic 260 — Earnings per Share ("ASC Topic 260"), basic earnings per share is computed by dividing earnings available to common equityholders by the weighted average number of shares outstanding during the period. Other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis. The following information sets forth the computation of the weighted average basic and diluted net increase in net assets attributed to common equityholders per share for the three and six months ended June 30, 2019 and June 30, 2018. For the three For the three For the six For the six Basic and diluted Increase in net assets attributed to common equityholders $ 6,053,520 $ 5,206,196 $ 10,485,742 $ 9,200,260 Weighted average common shares outstanding 43,145,574 27,522,492 41,338,528 25,866,495 Net increase in net assets attributed to common equityholders per share $ 0.14 $ 0.19 $ 0.25 $ 0.36
Revenue Recognition	Revenue Recognition To the extent the company expects to collect such amounts, interest income is recorded on an accrual basis. If there is reason to doubt an ability to collect such interest, interest receivable on loans and debt securities is not accrued for accounting purposes. Original issue discounts, market discounts or market premiums are accreted or amortized using the effective interest method as interest income. Prepayment premiums on loans and debt securities are recorded as interest income when received. Any application, origination or other fees earned by the company in arranging or issuing debt are amortized over the expected term of the loan. Loans are placed on non-accrual status when principal and interest are 90 days or more past due, or when there is a reasonable doubt that principal or interest will be collected. Accrued interest is generally reversed when a loan is placed on non-accrual. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management's judgment. Non-accrual loans are generally restored to accrual status when past due and principal and interest is paid and, in management's judgment, is likely to remain current. Dividend income is recorded (1) on the ex-dividend date for publicly issued securities and (2) when received from private investments. The timing and amount of dividend income is determined on at least a quarterly basis by GREC. This process includes an analysis at the individual SPV level based on cash available from operations and working capital ratios needed for the SPVs daily operations. Dividend income from our privately held, equity investments are recognized when approved. Dividends received from the company's private investments, which generally reflect net cash flow from operations, are declared, accrued and paid on a quarterly basis at a minimum.
Net Realized Gains or Losses and Net Change in Unrealized Appreciation or Depreciation on Investments	Net Realized Gains or Losses and Net Change in Unrealized Appreciation or Depreciation on Investments Realized gains or losses will be measured as the difference between the net proceeds from the sale, repayment, or disposal of an asset and the adjusted cost basis of the asset, without regard to unrealized appreciation or depreciation previously recognized. Net change in unrealized appreciation or depreciation will reflect the change in investment values during the reporting period, including any reversal of previously recorded unrealized appreciation or depreciation, when gains or losses are realized.
Payment-in-Kind Interest	Payment-in-Kind Interest For loans and debt securities with contractual payment-in-kind interest, if the valuation indicates that such interest is collectible, any interest will be added to the principal balance of such investments and be recorded as income.
Distribution Policy	Distribution Policy Distributions to members, if any, will be authorized and declared by our board of directors quarterly in advance and paid monthly. From time to time, we may also pay interim special distributions in the form of cash or shares, with the approval of our board of directors. Distributions will be made on all classes of shares at the same time. The cash distributions with respect to the Class C shares will be lower than the cash distributions with respect to the company's other share classes because of the distribution fee associated with the Class C shares, which is allocated specifically to Class C net assets. Amounts distributed to each class are allocated amongst the holders of the shares in such class in proportion to their shares. Distributions declared by our board of directors are recognized as distribution liabilities on the ex-dividend date.
Organization and Offering Costs	Organization and Offering Costs Organization and offering costs (“O&O costs”), other than sales commissions and the dealer manager fee, were initially paid by our advisor and/or dealer manager on behalf of the company. These O&O costs included all costs previously paid or to be paid by the company in connection with its formation and the offering of its shares pursuant to now-terminated Registration Statements on Form S-1 (File No. 333-178786-01 333-211571 The company was obligated to reimburse our advisor for O&O costs that it incurred on behalf of the company, in accordance with the advisory agreement, but only to the extent that the reimbursement would not cause the selling commissions, the dealer manager fee and the other organization and offering expenses borne by the company to exceed 15% of gross offering proceeds as of the date of reimbursement. Total O&O costs related to the terminated Registration Statements amounted to $9.4 million approximately 3.8% of gross offering proceeds raised pursuant to such Registration Statements. The costs incurred by our advisor and/or dealer manager are recognized as a liability of the company to the extent that the company is obligated to reimburse our advisor and/or dealer manager, subject to the 15% of gross offering proceeds limitation described above. When recognized by the company, organizational costs are expensed and offering costs, excluding selling commissions and dealer manager fees, are recognized as a reduction of the proceeds from the offering. The following table provides information regarding the status of O&O costs (in 000’s) as of June 30, 2019 and December 31, 2018: June 30, December 31, Total O&O Costs Incurred by the Advisor and Dealer Manager $ 9,422 $ 9,371 Amounts previously reimbursed to the Advisor/Dealer Manager by the company 9,422 9,106 Amounts payable to Advisor/Dealer Manager by the company ‒‒ 19 Amounts of the contingent liability subject to payment by the company only upon adequate gross offering proceeds being raised ‒‒ 246
Financing Costs	Financing Costs Financing costs related to debt liabilities incurred by the company, GREC or any wholly-owned holding company formed specifically to be a credit agreement counterparty are presented on the consolidated statements of assets and liabilities as a direct deduction from the carrying amount of that debt liability. Financing costs are deferred and amortized using the straight-line method over the life of the debt liability.
Capital Gains Incentive Allocation and Distribution	Capital Gains Incentive Allocation and Distribution Pursuant to the terms of the LLC's amended and restated limited liability company agreement, a capital gains incentive fee will be earned by an affiliate of our advisor on realized gains (net of realized and unrealized losses) since inception from the sale of investments from the company's portfolio during operations prior to a liquidation of the company. While the terms of the advisory agreement neither include nor contemplate the inclusion of unrealized gains in the calculation of the capital gains incentive fee, the company will include unrealized gains in the calculation of the capital gains incentive distribution pursuant to an interpretation of an American Institute for Certified Public Accountants Technical Practice Aid for investment companies. Even though the advisor is not entitled to an incentive distribution with respect to unrealized gains unless and until such gains are realized, this amount reflects the incentive distribution that would be payable if the company's entire portfolio was liquidated at its fair value as of the consolidated statements of assets and liabilities date. Thus, on each date that net asset value is calculated, the company calculates for the capital gains incentive distribution by calculating such distribution as if it were due and payable as of the end of such period and reflected as an allocation of equity between common equityholders and special unitholder. As of June 30, 2019, and December 31, 2018, a capital gains incentive distribution allocation in the amounts of $3,233,426 and $1,797,138, respectively, was recorded in the consolidated statements of assets and liabilities as special unitholder's equity.
Deferred Sales Commissions	Deferred Sales Commissions The company defers certain costs, principally sales commissions and related compensation, which are paid to the dealer manager and may be reallowed to financial advisors and broker/dealers in connection with the sale of Class C shares sold with a reduced front-end load sales charge. The costs expected to be incurred at the time of the sale of Class C shares are recorded as a liability on the date of sale and are amortized on a straight-line basis over the period beginning at the time of sale and ending on the date which approximates an expected liquidity event for the company. As of June 30, 2019, and December 31, 2018, the company recorded a liability for deferred sales commissions in the amount of $142,511 and $191,706, respectively.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform with current year presentation.
Derivative Instruments	Derivative Instruments The company may utilize interest rate swaps to modify interest rate characteristics of existing debt obligations to manage interest rate exposure. These are recorded at fair value either as assets or liabilities in the accompanying consolidated statements of assets and liabilities with changes in the fair value of interest rate swaps during the period recognized as either an unrealized gain or loss in the accompanying consolidated statements of operations. The fair value of interest rate swap contracts open as of June 30, 2019 is included on the consolidated schedules of investments by contract. For the six months ended June 30, 2019, the company's notional exposure to interest rate swap contracts was $95,072,098.

The company's exposure to credit risk associated with counterparty non-performance is limited to collateral posted and the unrealized gains that are recognized in the consolidated statement of assets and liabilities. The company minimizes counterparty credit risk through credit monitoring procedures and managing margin and collateral requirements, as appropriate. In regard to our investment in the Canadian Northern Lights Portfolio, we have foreign currency risk related to our revenue and operating expenses which are denominated in the Canadian Dollars as opposed to the U.S. Dollars. While we are currently of the opinion that the currency fluctuation between the Canadian and U.S. Dollar will not have a material impact on our operating results, we may in the future hedge this risk using currency swap transactions or other financial instruments if the impact on our results of operations becomes material.
Income Taxes	Income Taxes The company intends to operate so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code. As such, it will not be subject to any U.S. federal and state income taxes. In any year, it is possible that the company will not meet the qualifying income exception and will not qualify to be treated as a partnership. If the company does not meet the qualifying income exception, the members would then be treated as stockholders in a corporation and the company would become taxable as a corporation for U.S. federal income tax purposes under the Internal Revenue Code. The company would be required to pay income tax at corporate rates on its net taxable income. Distributions to members from the company would constitute dividend income taxable to such members, to the extent of the company's earnings and profits and the payment of the distributions would not be deductible by the company. The LLC plans to conduct substantially all its operations through its wholly-owned subsidiary, GREC, which is a corporation that is subject to U.S. federal, state and local income taxes. Accordingly, most of its operations will be subject to U.S. federal, state and local income taxes. Income taxes are accounted for under the assets and liabilities method. Deferred tax assets and liabilities are recorded for the estimated future tax consequences attributable to differences between items that are recognized in the consolidated financial statements and tax returns in different years. 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 on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. For income tax benefits to be recognized including uncertain tax benefits, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of the benefit that is more likely than not to be realized upon ultimate settlement. A valuation allowance is established against net deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the net deferred tax assets will not be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Interest and penalties associated with income taxes, if any, will be recognized in general and administrative expense. The company does not consolidate its investments for financial statements. The company accounts for its investments at fair value under the specialized accounting of ASC Topic 946. The tax attributes of the individual investments will be considered and incorporated in the company's fair value estimates for those investments. The amounts recognized in the consolidated financial statements for unrealized appreciation and depreciation will result in a difference between the consolidated financial statements and the cost basis of the assets for tax purposes. These differences will be recognized as deferred tax assets and liabilities. Generally, the entities that hold the company's investments will be included in the consolidated tax return of GREC and the differences between the amounts recognized for financial statement purposes and the tax return will be recognized as additional deferred tax assets and liabilities. The company follows the authoritative guidance on accounting for uncertainty in income taxes and concluded it has no material uncertain tax positions to be recognized at this time. The company assessed its tax positions for all open tax years as of June 30, 2019 for all U.S. federal and state tax jurisdictions for the years 2015 through 2018. The results of this assessment are included in the company's tax provision and deferred tax assets as of June 30, 2019.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement", which modifies the disclosure requirements on fair value measurements. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (fiscal 2020 for the company). Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. We are currently evaluating the impact of the amendments on our consolidated financial statement disclosures. Since the amendments impact only disclosure requirements, we do not expect the amendments to have an impact on our consolidated financial statements.
