ORGANIZATION	NOTE 1 – ORGANIZATION In this report, we generally refer to Mill City Ventures III, Ltd. in the first person “we.” On occasion, we refer to our company in the third person as “Mill City Ventures” or the “Company.” The Company follows accounting and reporting guidance in Accounting Standards (“ASC”) 946. We were incorporated in Minnesota in January 2006. Until December 13, 2012, we were a development-stage company that focused on promoting and placing a proprietary poker game online and into casinos and entertainment facilities nationwide. In 2013, we elected to become a business development company (“BDC”) under the Investment Company Act of 1940 (the “1940 Act”). We operated as a BDC until we withdrew our BDC election on December 27, 2019. As of the time of this filing, we remain a public reporting company that files periodic reports with the SEC. We offer short-term specialty finance solutions primarily to private businesses, small-cap public companies and high-net-worth individuals. To avoid regulation under the 1940 Act, we generally seek to structure our investments so they do not constitute “investment securities” for purposes of federal securities law, and we monitor our investments as a whole to ensure that no more than 40% of our total assets may consist of investment securities.

For further information, refer to the financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021. Use of estimates: Cash deposits: Valuation of portfolio investments: Due to the inherent uncertainties of valuation, certain estimated fair values may differ significantly from the values that would have been realized had a ready market for these investments existed, and these differences could be material. In addition, such investments are generally less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it. Accounting guidance establishes a hierarchal disclosure framework that prioritizes and ranks the level of market price observability of inputs used in measuring investments at fair value. Observable inputs must be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available. Assets and liabilities measured at fair value are to be categorized into one of the three hierarchy levels based on the relative observability of inputs used in the valuation. The three levels are defined as follows: ● Level 1: Observable inputs based on quoted prices (unadjusted) in active markets for identical assets or liabilities. ● Level 2: Observable inputs based on quoted prices for similar assets and liabilities in active markets, or quoted prices for identical assets and liabilities in inactive markets. ● Level 3: Unobservable inputs that reflect an entity’s own assumptions about what inputs a market participant would use in pricing the asset or liability based on the best information available in the circumstances. Our valuation policy and procedures The estimated fair value of our Level 3 investment assets is determined on a quarterly basis by our Board of Directors, pursuant to our written Valuation Policy and Procedures. These policies and procedures generally require that we value our Level 3 equity investments at cost plus any accrued interest, unless circumstances warrant a different approach. Our Valuation Policy and Procedures provide examples of these circumstances, such as when a portfolio company has engaged in a subsequent financing of more than a de minimis When valuing preferred equity investments, we generally view intrinsic value as a key input. Intrinsic value means the value of any conversion feature (if the preferred investment is convertible) or the value of any liquidation or other preference. Discounts to intrinsic value may be applied in cases where the issuer’s financial condition is impaired or, in cases where intrinsic value relating to a conversion is determined to be a key input, to account for resale restrictions applicable to the securities issuable upon conversion. When valuing warrants, our Valuation Policy and Procedures indicate that value will generally be the difference between closing price of the underlying equity security and the exercise price, after applying an appropriate discount for restriction, if applicable, in situations where the underlying security is marketable. If the underlying security is not marketable, then intrinsic value will be considered consistent with the principles described above. Generally, “out-of-the-money” warrants will be valued at cost or zero. For non-traded (Level 3) debt securities with a residual maturity less than or equal to 60 days, the value will generally be based on a present value approach, considering the straight-line amortized face value of the debt unless justification for impairment exists. The fair value for short-term non-banking loans is determined as the present value of future contractual cash flows discounted at an interest rate that reflects the risks inherent to those cash flows. The discount ranges from 12% to 48% and approximate rates currently observed in publicly traded debt markets for debt of similar terms to companies with comparable credit risk. On a quarterly basis, our management provides members of our Board of Directors with (i) valuation updates for each portfolio investment; (ii) Mill City Ventures’ bank and other statements pertaining to our cash and cash equivalents; (iii) quarter- or period-end statements from our custodial firms holding any of our portfolio investments; and (iv) recommendations to change any existing valuations of our portfolio investments or hierarchy levels for purposes of determining the fair value of such investments based upon the foregoing. The board then discusses these materials and, consistent with the policies and approaches outlined above, makes final determinations respecting the valuation and hierarchy levels of our portfolio investments. Income taxes: We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. In the event we were to determine we would be able to realize our deferred income tax assets in the future in excess of their recorded amount, we would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. We file income tax returns in the U.S. Federal jurisdiction and various state jurisdictions. We do not believe there will be any material changes in its unrecognized tax positions over the next 12 months. Our evaluation was performed for the tax years ended December 31, 2019 through 2021, which are the tax years that remain subject to examination by major tax jurisdictions as of March 31, 2022. Revenue recognition Interest income, adjusted for amortization of premiums and accretion of discounts, is recorded on an accrual basis. Discounts from and premiums to par value on securities purchased are accreted or amortized, as applicable, into interest income over the life of the related security using the effective-yield method. The amortized cost of investments represents the original cost, adjusted for the accretion of discounts and amortization of premiums, if any. Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more, or when there is reasonable doubt that principal or interest will be collected in full. Loan origination fees are recognized when loans are issued. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past-due principal and interest is paid and, in management’s judgment, are likely to remain current. We may make exceptions to the policy described above if a loan has sufficient collateral value and is in the process of collection. Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Certain investments may have contractual payment-in-kind (“PIK”) interest or dividends. PIK represents accrued interest or accumulated dividends that are added to the loan principal or stated value of the investment on the respective interest- or dividend-payment dates rather than being paid in cash, and generally becomes due at maturity or upon being repurchased by the issuer. PIK interest or dividends is recorded as interest or dividend income, as applicable. If at any point we believe that PIK interest or dividends is not expected be realized, the PIK-generating investment will be placed on non-accrual status. Accrued PIK interest or dividends are generally reversed through interest or dividend income, respectively, when an investment in placed on non-accrual status. Allocation of net gains and losses: Management and service fees: We do not incur expenses related to management and service fees. Our executive management team manages our investments as part of their employment responsibilities.

Our valuation policy and procedures The estimated fair value of our Level 3 investment assets is determined on a quarterly basis by the Valuation Committee of our Board of Directors, pursuant to our written Valuation Policy and Procedures. These policies and procedures generally require that we value our Level 3 equity investments at cost plus any accrued interest, unless circumstances warrant a different approach. Our Valuation Policy and Procedures provide examples of these circumstances, such as when a portfolio company has engaged in a subsequent financing of more than a de minimis When valuing preferred equity investments, we generally view intrinsic value as a key input.

For non-traded (Level 3) debt securities with a residual maturity less than or equal to 60 days, the value will generally be based on a present value approach, considering the straight-line amortized face value of the debt unless justification for impairment exists. On a quarterly basis, our management provides members of our Valuation Committee with (i) valuation reports for each portfolio investment (which reports include our cost,, the most recent prior valuation and any current proposed valuation, and an indication of the valuation methodology used, together with any other supporting materials); (ii) Mill City Ventures’ bank and other statements pertaining to our cash and cash equivalents; (iii) quarter- or period-end statements from our custodial firms holding any of our portfolio investments; and (iv) recommendations to change any existing valuations of our portfolio investments or hierarchy levels for purposes of determining the fair value of such investments based upon the foregoing. The committee then discusses these materials and, consistent with the policies and approaches outlined above, makes final determinations respecting the valuation and hierarchy levels of our portfolio investments. We made no changes to our Valuation Policy and Procedures during the reporting period. Income taxes: We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amounts and tax basis of assets and liabilities using enacted tax rates in effect for the tax year in which the differences are expected to reverse.

In the event we were to determine we would not be able to realize our deferred income tax assets, we would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. We file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. The Company does not believe there will be any material changes in its unrecognized tax positions over the next 12 months. Our evaluation was performed for the tax years ended December 31, 2018 through 2020, which are the tax years that remain subject to examination by the tax jurisdictions as of December 31, 2021.

INCOME TAXES	NOTE 6 – INCOME TAXES Presently, we are a c-Corporation for tax purposes and have booked an income tax provision for the periods described below. As of March 31, 2022 and December 31, 2021, we have a net deferred tax liability of $39,000 and $45,000, respectively. Our determination of the realizable deferred tax assets and liabilities requires the exercise of significant judgment, based in part on business plans and expectations about future outcomes. In the event the actual results differ from these estimates in future periods, we may need to record a valuation allowance, which could materially impact our financial position and results of operations. We will continue to assess the need for a valuation allowance in future periods. As of March 31, 2022 and December 31, 2021 we had accrued income taxes of $1,434,000 and $1,269,000, respectively. We recorded income taxes of $159,000 (28 percent effective tax rate) and $662,691 (29 percent effective tax rate) during the three months ended March 31, 2022 and March 31, 2021, respectively. $1,362,000 of federal and state tax payments were made after March 31, 2022. As of December 31, 2020, we had a federal NOL of approximately $350,000. The remaining federal NOL was used in its entirety to offset taxable income during the 2021 tax year. At March 31, 2022, we have no federal or state NOLs available to offset taxable income, all NOLs have been exhausted. Due to tax reform enacted in 2017, any newly created NOLs will carry forward indefinitely.	NOTE 10 – INCOME TAXES Presently, we are a “C-corporation” for tax purposes and have booked an income tax provision for the year ended December 31, 2021.

We expect the Federal net operating loss to be completely used and offset taxable income by December 31, 2021. The federal NOL may be carried forward to offset future taxable income, subject to applicable provisions of the Internal Revenue Code. Certain federal NOLs will expire in years 2036 and 2037 if not used. Due to tax reform enacted in 2017, NOLs created after 2017 carry forward indefinitely. The estimated federal NOL that does not expire included in the total above is $350,000. The Company had Minnesota net operating loss carryforwards of approximately $1,330,000 at December 31, 2020. We expect the state net operating loss to be completely used and offset taxable income by December 31, 2021. States may vary in their treatment of post-2017 NOLs. We lost some state NOL carryforwards when we filed final 2019 tax returns in several states. The remaining state NOL carryforwards may expire in 2036 and 2037 if not used. 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. Significant components of our deferred tax assets and liabilities as of December 31, 2021 and 2020 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ 2021 2020 Deferred tax components ​ ​ ​ ​ Unrealized (gain) loss on marketable securities ​ $ (46,552) ​ $ (488,419) Depreciation ​ 2,458 ​ 3,002 Net operating loss carryforwards ​ — ​ 180,460 R&D and foreign credits ​ — ​ 46,957 Other ​ (906) ​ — Net deferred tax asset (liability) ​ $ (45,000) ​ $ (258,000) ​

SUBSEQUENT EVENTS
SUBSEQUENT EVENTS	NOTE 12 – Subsequent Events On April 11, 2022, we issued 15,000 shares of restricted common stock to each of our three independent directors, and 10,000 shares of restricted common stock to our two non-independent directors. The shares are subject to forfeiture in the event the recipients are terminated from their board positions or employment, if applicable, on or prior to January 23, 2023. On April 12, 2022 we received $3,900,000 in advanced principal repayment of a short-term loan that had a maturity date of September 27, 2022. The note bore interest at a rate of 12%. On April 18, 2022 we received $1,800,000 in advanced principal repayment of a short-term loan that had a maturity date of September 30, 2022. The note bore interest at a rate of 23%. On April 26, 2022, we filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission seeking to register an offer and sale of shares of our common stock in a firm-commitment underwritten offering.	NOTE 12 – SUBSEQUENT EVENTS On January 3, 2022, we entered into a Loan and Security Agreement (the “Loan Agreement”) with Eastman Investment, Inc., a Nevada corporation, and Lyle A. Berman, as trustee of the Lyle A. Berman Revocable Trust (collectively, the “Lenders”). Mr. Berman is a director of our company. Under the Loan Agreement, the Lenders made available to us a $5 million revolving line of credit for us to use in the ordinary course of our short-term specialty finance business. Amounts drawn under the Loan Agreement will accrue interest at the per annum rate of 8%, and all our obligations under the Loan Agreement are secured by a grant of a collateral security interest in substantially all of our assets. ​ Each Lender is obligated to furnish only one ​ The Loan Agreement provides for us to pay a quarterly unused commitment fee equal to one-quarter of one ​ The Loan Agreement contains other provisions, such as representations, warranties, terms and conditions, that are customary for revolving credit facilities. Promissory notes, evidencing amounts owing under the Loan Agreement and conforming to the terms and conditions of the Loan Agreement, were also executed by us and delivered to the Lenders as contemplated under the Loan Agreement. ​ On January 12, 2022, we entered into a $2,500,000 revolving credit and security loan investment bearing interest at 15%. On January 12, 2022, we advanced $1,250,000 under this loan, and an additional $960,000 on January 26, 2022. ​ On January 26, 2022, we invested $ 1,125,000 in a 120-day promissory note bearing interest at 33.33%. ​ On February 11, 2022, we filed a registration statement on Form S-1 seeking to register an offering of five-year common stock warrants which we may distribute to our shareholders as a dividend, and up to 2,697,603 shares of our common stock purchasable upon the exercise of those warrants. The warrants are contemplated to be exercisable at a price of $4.00 per share of common stock. We intend to apply to have the warrants listed for trading on the OTC Markets. ​ The offering is subject to the effectiveness of the S-1 registration statement. At this time, no record date has been established for the dividend. The warrants will not be issued until the registration statement is declared effective, and the warrants will not be exercisable unless such registration statement remains effective. If the offering is consummated, we expect to use net proceeds from the offering for general corporate purposes, including but not limited to extending specialty finance solutions and credit to borrowers and repaying credit facility borrowings. ​ On March 7, 2022, the company funded a $3.4 million short-term loan, the proceeds of which will be used to acquire real estate located in Glendale, Arizona, where 139 townhouse units are expected to be developed by the borrower. The short-term loan accrues interest at the per annum rate of 48%, and the loan is due on May 30, 2022. ​

Valuation of portfolio investments:	Valuation of portfolio investments: Due to the inherent uncertainties of valuation, certain estimated fair values may differ significantly from the values that would have been realized had a ready market for these investments existed, and these differences could be material. In addition, such investments are generally less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it. Accounting guidance establishes a hierarchal disclosure framework that prioritizes and ranks the level of market price observability of inputs used in measuring investments at fair value. Observable inputs must be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available. Assets and liabilities measured at fair value are to be categorized into one of the three hierarchy levels based on the relative observability of inputs used in the valuation. The three levels are defined as follows: ● Level 1: Observable inputs based on quoted prices (unadjusted) in active markets for identical assets or liabilities. ● Level 2: Observable inputs based on quoted prices for similar assets and liabilities in active markets, or quoted prices for identical assets and liabilities in inactive markets. ● Level 3: Unobservable inputs that reflect an entity’s own assumptions about what inputs a market participant would use in pricing the asset or liability based on the best information available in the circumstances.

Our valuation policy and procedures:	Our valuation policy and procedures The estimated fair value of our Level 3 investment assets is determined on a quarterly basis by our Board of Directors, pursuant to our written Valuation Policy and Procedures. These policies and procedures generally require that we value our Level 3 equity investments at cost plus any accrued interest, unless circumstances warrant a different approach. Our Valuation Policy and Procedures provide examples of these circumstances, such as when a portfolio company has engaged in a subsequent financing of more than a de minimis When valuing preferred equity investments, we generally view intrinsic value as a key input. Intrinsic value means the value of any conversion feature (if the preferred investment is convertible) or the value of any liquidation or other preference. Discounts to intrinsic value may be applied in cases where the issuer’s financial condition is impaired or, in cases where intrinsic value relating to a conversion is determined to be a key input, to account for resale restrictions applicable to the securities issuable upon conversion. When valuing warrants, our Valuation Policy and Procedures indicate that value will generally be the difference between closing price of the underlying equity security and the exercise price, after applying an appropriate discount for restriction, if applicable, in situations where the underlying security is marketable. If the underlying security is not marketable, then intrinsic value will be considered consistent with the principles described above. Generally, “out-of-the-money” warrants will be valued at cost or zero. For non-traded (Level 3) debt securities with a residual maturity less than or equal to 60 days, the value will generally be based on a present value approach, considering the straight-line amortized face value of the debt unless justification for impairment exists. The fair value for short-term non-banking loans is determined as the present value of future contractual cash flows discounted at an interest rate that reflects the risks inherent to those cash flows. The discount ranges from 12% to 48% and approximate rates currently observed in publicly traded debt markets for debt of similar terms to companies with comparable credit risk. On a quarterly basis, our management provides members of our Board of Directors with (i) valuation updates for each portfolio investment; (ii) Mill City Ventures’ bank and other statements pertaining to our cash and cash equivalents; (iii) quarter- or period-end statements from our custodial firms holding any of our portfolio investments; and (iv) recommendations to change any existing valuations of our portfolio investments or hierarchy levels for purposes of determining the fair value of such investments based upon the foregoing. The board then discusses these materials and, consistent with the policies and approaches outlined above, makes final determinations respecting the valuation and hierarchy levels of our portfolio investments.

On a quarterly basis, our management provides members of our Valuation Committee with (i) valuation reports for each portfolio investment (which reports include our cost,, the most recent prior valuation and any current proposed valuation, and an indication of the valuation methodology used, together with any other supporting materials); (ii) Mill City Ventures’ bank and other statements pertaining to our cash and cash equivalents; (iii) quarter- or period-end statements from our custodial firms holding any of our portfolio investments; and (iv) recommendations to change any existing valuations of our portfolio investments or hierarchy levels for purposes of determining the fair value of such investments based upon the foregoing. The committee then discusses these materials and, consistent with the policies and approaches outlined above, makes final determinations respecting the valuation and hierarchy levels of our portfolio investments. We made no changes to our Valuation Policy and Procedures during the reporting period.
Income taxes:	Income taxes: We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. In the event we were to determine we would be able to realize our deferred income tax assets in the future in excess of their recorded amount, we would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. We file income tax returns in the U.S. Federal jurisdiction and various state jurisdictions. We do not believe there will be any material changes in its unrecognized tax positions over the next 12 months. Our evaluation was performed for the tax years ended December 31, 2019 through 2021, which are the tax years that remain subject to examination by major tax jurisdictions as of March 31, 2022.

Revenue recognition:	Revenue recognition Interest income, adjusted for amortization of premiums and accretion of discounts, is recorded on an accrual basis. Discounts from and premiums to par value on securities purchased are accreted or amortized, as applicable, into interest income over the life of the related security using the effective-yield method. The amortized cost of investments represents the original cost, adjusted for the accretion of discounts and amortization of premiums, if any. Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more, or when there is reasonable doubt that principal or interest will be collected in full. Loan origination fees are recognized when loans are issued. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past-due principal and interest is paid and, in management’s judgment, are likely to remain current. We may make exceptions to the policy described above if a loan has sufficient collateral value and is in the process of collection. Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Certain investments may have contractual payment-in-kind (“PIK”) interest or dividends. PIK represents accrued interest or accumulated dividends that are added to the loan principal or stated value of the investment on the respective interest- or dividend-payment dates rather than being paid in cash, and generally becomes due at maturity or upon being repurchased by the issuer. PIK interest or dividends is recorded as interest or dividend income, as applicable. If at any point we believe that PIK interest or dividends is not expected be realized, the PIK-generating investment will be placed on non-accrual status. Accrued PIK interest or dividends are generally reversed through interest or dividend income, respectively, when an investment in placed on non-accrual status.

SIGNIFICANT ACCOUNTING POLICIES
SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The condensed balance sheet as of December 31, 2021 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021. Use of estimates: Cash deposits: Valuation of portfolio investments: Due to the inherent uncertainties of valuation, certain estimated fair values may differ significantly from the values that would have been realized had a ready market for these investments existed, and these differences could be material. In addition, such investments are generally less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it. Accounting guidance establishes a hierarchal disclosure framework that prioritizes and ranks the level of market price observability of inputs used in measuring investments at fair value. Observable inputs must be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available. Assets and liabilities measured at fair value are to be categorized into one of the three hierarchy levels based on the relative observability of inputs used in the valuation. The three levels are defined as follows: ● Level 1: Observable inputs based on quoted prices (unadjusted) in active markets for identical assets or liabilities. ● Level 2: Observable inputs based on quoted prices for similar assets and liabilities in active markets, or quoted prices for identical assets and liabilities in inactive markets. ● Level 3: Unobservable inputs that reflect an entity’s own assumptions about what inputs a market participant would use in pricing the asset or liability based on the best information available in the circumstances. Our valuation policy and procedures The estimated fair value of our Level 3 investment assets is determined on a quarterly basis by our Board of Directors, pursuant to our written Valuation Policy and Procedures. These policies and procedures generally require that we value our Level 3 equity investments at cost plus any accrued interest, unless circumstances warrant a different approach. Our Valuation Policy and Procedures provide examples of these circumstances, such as when a portfolio company has engaged in a subsequent financing of more than a de minimis When valuing preferred equity investments, we generally view intrinsic value as a key input. Intrinsic value means the value of any conversion feature (if the preferred investment is convertible) or the value of any liquidation or other preference. Discounts to intrinsic value may be applied in cases where the issuer’s financial condition is impaired or, in cases where intrinsic value relating to a conversion is determined to be a key input, to account for resale restrictions applicable to the securities issuable upon conversion. When valuing warrants, our Valuation Policy and Procedures indicate that value will generally be the difference between closing price of the underlying equity security and the exercise price, after applying an appropriate discount for restriction, if applicable, in situations where the underlying security is marketable. If the underlying security is not marketable, then intrinsic value will be considered consistent with the principles described above. Generally, “out-of-the-money” warrants will be valued at cost or zero. For non-traded (Level 3) debt securities with a residual maturity less than or equal to 60 days, the value will generally be based on a present value approach, considering the straight-line amortized face value of the debt unless justification for impairment exists. The fair value for short-term non-banking loans is determined as the present value of future contractual cash flows discounted at an interest rate that reflects the risks inherent to those cash flows. The discount ranges from 12% to 48% and approximate rates currently observed in publicly traded debt markets for debt of similar terms to companies with comparable credit risk. On a quarterly basis, our management provides members of our Board of Directors with (i) valuation updates for each portfolio investment; (ii) Mill City Ventures’ bank and other statements pertaining to our cash and cash equivalents; (iii) quarter- or period-end statements from our custodial firms holding any of our portfolio investments; and (iv) recommendations to change any existing valuations of our portfolio investments or hierarchy levels for purposes of determining the fair value of such investments based upon the foregoing. The board then discusses these materials and, consistent with the policies and approaches outlined above, makes final determinations respecting the valuation and hierarchy levels of our portfolio investments. Income taxes: We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. In the event we were to determine we would be able to realize our deferred income tax assets in the future in excess of their recorded amount, we would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. We file income tax returns in the U.S. Federal jurisdiction and various state jurisdictions. We do not believe there will be any material changes in its unrecognized tax positions over the next 12 months. Our evaluation was performed for the tax years ended December 31, 2019 through 2021, which are the tax years that remain subject to examination by major tax jurisdictions as of March 31, 2022. Revenue recognition Interest income, adjusted for amortization of premiums and accretion of discounts, is recorded on an accrual basis. Discounts from and premiums to par value on securities purchased are accreted or amortized, as applicable, into interest income over the life of the related security using the effective-yield method. The amortized cost of investments represents the original cost, adjusted for the accretion of discounts and amortization of premiums, if any. Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more, or when there is reasonable doubt that principal or interest will be collected in full. Loan origination fees are recognized when loans are issued. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past-due principal and interest is paid and, in management’s judgment, are likely to remain current. We may make exceptions to the policy described above if a loan has sufficient collateral value and is in the process of collection. Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Certain investments may have contractual payment-in-kind (“PIK”) interest or dividends. PIK represents accrued interest or accumulated dividends that are added to the loan principal or stated value of the investment on the respective interest- or dividend-payment dates rather than being paid in cash, and generally becomes due at maturity or upon being repurchased by the issuer. PIK interest or dividends is recorded as interest or dividend income, as applicable. If at any point we believe that PIK interest or dividends is not expected be realized, the PIK-generating investment will be placed on non-accrual status. Accrued PIK interest or dividends are generally reversed through interest or dividend income, respectively, when an investment in placed on non-accrual status.

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of estimates: Cash deposits: Valuation of portfolio investments: Due to the inherent uncertainties of valuation, certain estimated fair values may differ significantly from the values that would have been realized had a ready market for these investments existed, and these differences could be material. In addition, such investments are generally less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it. Accounting guidance establishes a hierarchal disclosure framework that prioritizes and ranks the level of market price observability of inputs used in measuring investments at fair value. Observable inputs must be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available. Assets and liabilities measured at fair value are to be categorized into one of the three hierarchy levels based on the relative observability of inputs used in the valuation. The three levels are defined as follows: ● Level 1: Observable inputs based on quoted prices (unadjusted) in active markets for identical assets or liabilities. ● Level 2: Observable inputs based on quoted prices for similar assets and liabilities in active markets, or quoted prices for identical assets and liabilities in inactive markets. ● Level 3: Unobservable inputs that reflect an entity’s own assumptions about what inputs a market participant would use in pricing the asset or liability based on the best information available in the circumstances. Our valuation policy and procedures The estimated fair value of our Level 3 investment assets is determined on a quarterly basis by the Valuation Committee of our Board of Directors, pursuant to our written Valuation Policy and Procedures. These policies and procedures generally require that we value our Level 3 equity investments at cost plus any accrued interest, unless circumstances warrant a different approach. Our Valuation Policy and Procedures provide examples of these circumstances, such as when a portfolio company has engaged in a subsequent financing of more than a de minimis When valuing preferred equity investments, we generally view intrinsic value as a key input. Intrinsic value means the value of any conversion feature (if the preferred investment is convertible) or the value of any liquidation or other preference. Discounts to intrinsic value may be applied in cases where the issuer’s financial condition is impaired or, in cases where intrinsic value relating to a conversion is determined to be a key input, to account for resale restrictions applicable to the securities issuable upon conversion. When valuing warrants, our Valuation Policy and Procedures indicate that value will generally be the difference between closing price of the underlying equity security and the exercise price, after applying an appropriate discount for restriction, if applicable, in situations where the underlying security is marketable. If the underlying security is not marketable, then intrinsic value will be considered consistent with the principles described above. Generally, “out-of-the-money” warrants will be valued at cost or zero. For non-traded (Level 3) debt securities with a residual maturity less than or equal to 60 days, the value will generally be based on a present value approach, considering the straight-line amortized face value of the debt unless justification for impairment exists. On a quarterly basis, our management provides members of our Valuation Committee with (i) valuation reports for each portfolio investment (which reports include our cost,, the most recent prior valuation and any current proposed valuation, and an indication of the valuation methodology used, together with any other supporting materials); (ii) Mill City Ventures’ bank and other statements pertaining to our cash and cash equivalents; (iii) quarter- or period-end statements from our custodial firms holding any of our portfolio investments; and (iv) recommendations to change any existing valuations of our portfolio investments or hierarchy levels for purposes of determining the fair value of such investments based upon the foregoing. The committee then discusses these materials and, consistent with the policies and approaches outlined above, makes final determinations respecting the valuation and hierarchy levels of our portfolio investments. We made no changes to our Valuation Policy and Procedures during the reporting period. Income taxes: We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amounts and tax basis of assets and liabilities using enacted tax rates in effect for the tax year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income for the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and recent financial operations. In the event we were to determine we would not be able to realize our deferred income tax assets, we would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. We file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. The Company does not believe there will be any material changes in its unrecognized tax positions over the next 12 months. Our evaluation was performed for the tax years ended December 31, 2018 through 2020, which are the tax years that remain subject to examination by the tax jurisdictions as of December 31, 2021. Revenue recognition Interest income, adjusted for amortization of premiums and accretion of discounts, is recorded on an accrual basis. Discounts from and premiums to par value on securities purchased are accreted or amortized, as applicable, into interest income over the life of the related security using the effective-yield method. The amortized cost of investments represents the original cost, adjusted for the accretion of discounts and amortization of premiums, if any. Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more, or when there is reasonable doubt that principal or interest will be collected in full. Loan origination fees are recognized when loans are issued. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past-due principal and interest is paid and, in management’s judgment, are likely to remain current. We may make exceptions to the policy described above if a loan has sufficient collateral value and is in the process of collection. Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Certain investments may have contractual payment-in-kind (“PIK”) interest or dividends. PIK represents accrued interest or accumulated dividends that are added to the loan principal or stated value of the investment on the respective interest- or dividend-payment dates rather than being paid in cash, and generally becomes due at maturity or upon being repurchased by the issuer. PIK interest or dividends is recorded as interest or dividend income, as applicable. If at any point we believe that PIK interest or dividends is not expected be realized, the PIK-generating investment will be placed on non-accrual status. Accrued PIK interest or dividends are generally reversed through interest or dividend income, respectively, when an investment in placed on non-accrual status.

INCOME TAXES	NOTE 6 – INCOME TAXES Presently, we are a c-Corporation for tax purposes and have booked an income tax provision for the periods described below. As of March 31, 2022 and December 31, 2021, we have a net deferred tax liability of $39,000 and $45,000, respectively. Our determination of the realizable deferred tax assets and liabilities requires the exercise of significant judgment, based in part on business plans and expectations about future outcomes. In the event the actual results differ from these estimates in future periods, we may need to record a valuation allowance, which could materially impact our financial position and results of operations. We will continue to assess the need for a valuation allowance in future periods. As of March 31, 2022 and December 31, 2021 we had accrued income taxes of $1,434,000 and $1,269,000, respectively. We recorded income taxes of $159,000 (28 percent effective tax rate) and $662,691 (29 percent effective tax rate) during the three months ended March 31, 2022 and March 31, 2021, respectively. $1,362,000 of federal and state tax payments were made after March 31, 2022. As of December 31, 2020, we had a federal NOL of approximately $350,000. The remaining federal NOL was used in its entirety to offset taxable income during the 2021 tax year. At March 31, 2022, we have no federal or state NOLs available to offset taxable income, all NOLs have been exhausted. Due to tax reform enacted in 2017, any newly created NOLs will carry forward indefinitely.	NOTE 10 – INCOME TAXES Presently, we are a “C-corporation” for tax purposes and have booked an income tax provision for the year ended December 31, 2021. Income taxes as of December 31, 2021, and 2020 are described below. ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ 2021 2020 Current taxes ​ ​ ​ ​ Federal ​ $ 909,530 ​ $ — State ​ 357,168 ​ 16,679 Deferred taxes ​ ​ Federal ​ (212,000) ​ 258,000 State ​ — ​ 13,722 Provision for income taxes ​ $ 1,054,698 ​ $ 288,401 ​ A reconciliation of income tax provisions at the U.S. statutory rate for fiscal year 2021 and 2020 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 Rate reconciliation: ​ ​ ​ ​ Tax expense at U.S.statutory rate ​ $ 1,017,417 ​ $ 716,966 Change in valuation allowance ​ — ​ (446,000) Provision-to-return reconciliation ​ (14,743) ​ 21,657 Other ​ (1,976) ​ (4,222) Income tax provision ​ $ 1,054,698 ​ $ 288,401 ​ The Company had Federal net operating loss carryforwards of approximately $350,000 at December 31, 2020. We expect the Federal net operating loss to be completely used and offset taxable income by December 31, 2021. The federal NOL may be carried forward to offset future taxable income, subject to applicable provisions of the Internal Revenue Code. Certain federal NOLs will expire in years 2036 and 2037 if not used. Due to tax reform enacted in 2017, NOLs created after 2017 carry forward indefinitely. The estimated federal NOL that does not expire included in the total above is $350,000. The Company had Minnesota net operating loss carryforwards of approximately $1,330,000 at December 31, 2020. We expect the state net operating loss to be completely used and offset taxable income by December 31, 2021. States may vary in their treatment of post-2017 NOLs. We lost some state NOL carryforwards when we filed final 2019 tax returns in several states. The remaining state NOL carryforwards may expire in 2036 and 2037 if not used. 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. Significant components of our deferred tax assets and liabilities as of December 31, 2021 and 2020 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ 2021 2020 Deferred tax components ​ ​ ​ ​ Unrealized (gain) loss on marketable securities ​ $ (46,552) ​ $ (488,419) Depreciation ​ 2,458 ​ 3,002 Net operating loss carryforwards ​ — ​ 180,460 R&D and foreign credits ​ — ​ 46,957 Other ​ (906) ​ — Net deferred tax asset (liability) ​ $ (45,000) ​ $ (258,000) ​

The shares are subject to forfeiture in the event the recipients are terminated from their board positions or employment, if applicable, on or prior to January 23, 2023. On April 12, 2022 we received $3,900,000 in advanced principal repayment of a short-term loan that had a maturity date of September 27, 2022. The note bore interest at a rate of 12%. On April 18, 2022 we received $1,800,000 in advanced principal repayment of a short-term loan that had a maturity date of September 30, 2022. The note bore interest at a rate of 23%. On April 26, 2022, we filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission seeking to register an offer and sale of shares of our common stock in a firm-commitment underwritten offering.	NOTE 12 – SUBSEQUENT EVENTS On January 3, 2022, we entered into a Loan and Security Agreement (the “Loan Agreement”) with Eastman Investment, Inc., a Nevada corporation, and Lyle A. Berman, as trustee of the Lyle A. Berman Revocable Trust (collectively, the “Lenders”). Mr. Berman is a director of our company. Under the Loan Agreement, the Lenders made available to us a $5 million revolving line of credit for us to use in the ordinary course of our short-term specialty finance business. Amounts drawn under the Loan Agreement will accrue interest at the per annum rate of 8%, and all our obligations under the Loan Agreement are secured by a grant of a collateral security interest in substantially all of our assets. ​ Each Lender is obligated to furnish only one ​ The Loan Agreement provides for us to pay a quarterly unused commitment fee equal to one-quarter of one ​ The Loan Agreement contains other provisions, such as representations, warranties, terms and conditions, that are customary for revolving credit facilities. Promissory notes, evidencing amounts owing under the Loan Agreement and conforming to the terms and conditions of the Loan Agreement, were also executed by us and delivered to the Lenders as contemplated under the Loan Agreement. ​ On January 12, 2022, we entered into a $2,500,000 revolving credit and security loan investment bearing interest at 15%. On January 12, 2022, we advanced $1,250,000 under this loan, and an additional $960,000 on January 26, 2022. ​ On January 26, 2022, we invested $ 1,125,000 in a 120-day promissory note bearing interest at 33.33%. ​ On February 11, 2022, we filed a registration statement on Form S-1 seeking to register an offering of five-year common stock warrants which we may distribute to our shareholders as a dividend, and up to 2,697,603 shares of our common stock purchasable upon the exercise of those warrants. The warrants are contemplated to be exercisable at a price of $4.00 per share of common stock. We intend to apply to have the warrants listed for trading on the OTC Markets. ​ The offering is subject to the effectiveness of the S-1 registration statement. At this time, no record date has been established for the dividend. The warrants will not be issued until the registration statement is declared effective, and the warrants will not be exercisable unless such registration statement remains effective. If the offering is consummated, we expect to use net proceeds from the offering for general corporate purposes, including but not limited to extending specialty finance solutions and credit to borrowers and repaying credit facility borrowings. ​ On March 7, 2022, the company funded a $3.4 million short-term loan, the proceeds of which will be used to acquire real estate located in Glendale, Arizona, where 139 townhouse units are expected to be developed by the borrower. The short-term loan accrues interest at the per annum rate of 48%, and the loan is due on May 30, 2022. ​

SIGNIFICANT ACCOUNTING POLICIES
Use of estimates:	Use of estimates:
Cash deposits:	Cash deposits:	Cash deposits:
Valuation of investments:	Valuation of portfolio investments: Due to the inherent uncertainties of valuation, certain estimated fair values may differ significantly from the values that would have been realized had a ready market for these investments existed, and these differences could be material. In addition, such investments are generally less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it. Accounting guidance establishes a hierarchal disclosure framework that prioritizes and ranks the level of market price observability of inputs used in measuring investments at fair value. Observable inputs must be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available. Assets and liabilities measured at fair value are to be categorized into one of the three hierarchy levels based on the relative observability of inputs used in the valuation. The three levels are defined as follows: ● Level 1: Observable inputs based on quoted prices (unadjusted) in active markets for identical assets or liabilities. ● Level 2: Observable inputs based on quoted prices for similar assets and liabilities in active markets, or quoted prices for identical assets and liabilities in inactive markets. ● Level 3: Unobservable inputs that reflect an entity’s own assumptions about what inputs a market participant would use in pricing the asset or liability based on the best information available in the circumstances.	Valuation of portfolio investments: Due to the inherent uncertainties of valuation, certain estimated fair values may differ significantly from the values that would have been realized had a ready market for these investments existed, and these differences could be material. In addition, such investments are generally less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it. Accounting guidance establishes a hierarchal disclosure framework that prioritizes and ranks the level of market price observability of inputs used in measuring investments at fair value. Observable inputs must be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available.

Our valuation policy and procedures:	Our valuation policy and procedures The estimated fair value of our Level 3 investment assets is determined on a quarterly basis by our Board of Directors, pursuant to our written Valuation Policy and Procedures. These policies and procedures generally require that we value our Level 3 equity investments at cost plus any accrued interest, unless circumstances warrant a different approach. Our Valuation Policy and Procedures provide examples of these circumstances, such as when a portfolio company has engaged in a subsequent financing of more than a de minimis When valuing preferred equity investments, we generally view intrinsic value as a key input. Intrinsic value means the value of any conversion feature (if the preferred investment is convertible) or the value of any liquidation or other preference. Discounts to intrinsic value may be applied in cases where the issuer’s financial condition is impaired or, in cases where intrinsic value relating to a conversion is determined to be a key input, to account for resale restrictions applicable to the securities issuable upon conversion. When valuing warrants, our Valuation Policy and Procedures indicate that value will generally be the difference between closing price of the underlying equity security and the exercise price, after applying an appropriate discount for restriction, if applicable, in situations where the underlying security is marketable. If the underlying security is not marketable, then intrinsic value will be considered consistent with the principles described above. Generally, “out-of-the-money” warrants will be valued at cost or zero. For non-traded (Level 3) debt securities with a residual maturity less than or equal to 60 days, the value will generally be based on a present value approach, considering the straight-line amortized face value of the debt unless justification for impairment exists. The fair value for short-term non-banking loans is determined as the present value of future contractual cash flows discounted at an interest rate that reflects the risks inherent to those cash flows. The discount ranges from 12% to 48% and approximate rates currently observed in publicly traded debt markets for debt of similar terms to companies with comparable credit risk. On a quarterly basis, our management provides members of our Board of Directors with (i) valuation updates for each portfolio investment; (ii) Mill City Ventures’ bank and other statements pertaining to our cash and cash equivalents; (iii) quarter- or period-end statements from our custodial firms holding any of our portfolio investments; and (iv) recommendations to change any existing valuations of our portfolio investments or hierarchy levels for purposes of determining the fair value of such investments based upon the foregoing. The board then discusses these materials and, consistent with the policies and approaches outlined above, makes final determinations respecting the valuation and hierarchy levels of our portfolio investments.

The committee then discusses these materials and, consistent with the policies and approaches outlined above, makes final determinations respecting the valuation and hierarchy levels of our portfolio investments. We made no changes to our Valuation Policy and Procedures during the reporting period.
Income taxes:	Income taxes: We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. In the event we were to determine we would be able to realize our deferred income tax assets in the future in excess of their recorded amount, we would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. We file income tax returns in the U.S. Federal jurisdiction and various state jurisdictions. We do not believe there will be any material changes in its unrecognized tax positions over the next 12 months. Our evaluation was performed for the tax years ended December 31, 2019 through 2021, which are the tax years that remain subject to examination by major tax jurisdictions as of March 31, 2022.

Revenue recognition:	Revenue recognition Interest income, adjusted for amortization of premiums and accretion of discounts, is recorded on an accrual basis. Discounts from and premiums to par value on securities purchased are accreted or amortized, as applicable, into interest income over the life of the related security using the effective-yield method. The amortized cost of investments represents the original cost, adjusted for the accretion of discounts and amortization of premiums, if any. Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more, or when there is reasonable doubt that principal or interest will be collected in full. Loan origination fees are recognized when loans are issued. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past-due principal and interest is paid and, in management’s judgment, are likely to remain current. We may make exceptions to the policy described above if a loan has sufficient collateral value and is in the process of collection. Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Certain investments may have contractual payment-in-kind (“PIK”) interest or dividends. PIK represents accrued interest or accumulated dividends that are added to the loan principal or stated value of the investment on the respective interest- or dividend-payment dates rather than being paid in cash, and generally becomes due at maturity or upon being repurchased by the issuer. PIK interest or dividends is recorded as interest or dividend income, as applicable. If at any point we believe that PIK interest or dividends is not expected be realized, the PIK-generating investment will be placed on non-accrual status. Accrued PIK interest or dividends are generally reversed through interest or dividend income, respectively, when an investment in placed on non-accrual status.
