Notes to Consolidated Financial Statements

ORGANIZATION AND BASIS OF PRESENTATION

References in this Quarterly Report on Form 10-Q to “we,” “our,” “us,” “CSWC,” or the “Company” refer to Capital Southwest Corporation, unless the context requires otherwise.

Organization

Capital Southwest Corporation is an internally managed investment company that specializes in providing customized financing to middle market companies in a broad range of industry segments located primarily in the United States. Our common stock currently trades on The Nasdaq Global Select Market under the ticker symbol “CSWC.”

CSWC was organized as a Texas corporation on April 19, 1961. On March 30, 1988, CSWC elected to be regulated as a business development company (“BDC”) subject to the provisions of the 1940 Act, as amended by the Small Business Incentive Act of 1980. In order to comply with the 1940 Act requirements for a BDC, we must, among other things, generally invest at least 70% of our assets in eligible portfolio companies and limit the amount of leverage we incur.

We have elected, and intend to qualify annually, to be treated as a regulated investment company (“RIC”) under Subchapter M of the U.S. Internal Revenue Code of 1986 (the “Code”). As such, we generally will not have to pay corporate-level U.S. federal income tax on any ordinary income or capital gains that we distribute to our shareholders as dividends. To continue to maintain our RIC treatment, we must meet specified source-of-income and asset diversification requirements and distribute annually at least 90% of our net ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any. Depending on the level of taxable income earned in a tax year, we may choose to carry forward taxable income in excess of current year distributions into the next year and pay a 4% excise tax on such income. Any such carryover taxable income must be distributed through a dividend declared prior to filing the final tax return related to the year that generated such taxable income.

Capital Southwest Management Corporation (“CSMC”), a wholly-owned subsidiary of CSWC, is the management company for CSWC. CSMC generally incurs all normal operating and administrative expenses, including, but not limited to, salaries and related benefits, rent, equipment and other administrative costs required for its day-to-day operations.

CSWC also has a direct wholly-owned subsidiary that has been elected to be a taxable entity (the “Taxable Subsidiary”). The primary purpose of the Taxable Subsidiary is to permit CSWC to hold certain interests in portfolio companies that are organized as limited liability companies, or LLCs (or other forms of pass-through entities) and still allow us to satisfy the RIC tax requirement that at least 90% of our gross income for federal income tax purposes must consist of qualifying investment income. The Taxable Subsidiary is taxed at normal corporate tax rates based on its taxable income.

We focus on investing in companies with histories of generating revenues and positive cash flow, established market positions and proven management teams with strong operating discipline. We target senior debt, subordinated debt and equity investments in lower middle market (“LMM”) companies, as well as first and second lien syndicated loans in upper middle market (“UMM”) companies. Our target LMM companies typically have annual earnings before interest, taxes, depreciation and amortization (“EBITDA”) between $3.0 million and $15.0 million, and our LMM investments generally range in size from $5.0 million to $25.0 million. Our UMM investments generally include syndicated first and second lien loans in companies with EBITDA generally greater than $50.0 million and typically range in size from $5.0 million to $15.0 million. We make available significant managerial assistance to the companies in which we invest as we believe that providing managerial assistance to an investee company is critical to its business development activities.

Basis of Presentation

The consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“U.S. GAAP”). We meet the definition of an investment company and follow the accounting and reporting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946 – Financial Services – Investment Companies (“ASC 946”) . Under rules and regulations applicable to investment companies, we are generally precluded from consolidating any entity other than another investment

Table of Contents

company, subject to certain exceptions. One of the exceptions to this general principle occurs if the investment company has an investment in an operating company that provides services to the investment company. Accordingly, the consolidated financial statements include CSMC, our management company, and the Taxable Subsidiary.

The consolidated financial statements are presented in conformity with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying annual consolidated financial statements prepared in accordance with U.S. GAAP are omitted. In the opinion of our management, the unaudited consolidated financial results included herein contain all adjustments, consisting solely of normal recurring accruals, considered necessary for the fair presentation of consolidated financial statements for the interim periods included herein. The results of operations for the three and six months ended September 30, 2018 are not necessarily indicative of the operating results to be expected for the full fiscal year. Also, the unaudited consolidated financial statements and notes should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal years ended March 31, 2018 and 2017 . Consolidated financial statements prepared on a U.S. GAAP basis require management to make estimates and assumptions that affect the amounts and disclosures reported in the consolidated financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein.

Portfolio Investment Classification

We classify our investments in accordance with the requirements of the 1940 Act. Under the 1940 Act, “Control Investments” are generally defined as investments in which we own more than 25% of the voting securities; “Affiliate Investments” are generally defined as investments in which we own between 5% and 25% of the voting securities, and the investments are not classified as “Control Investments”; and “Non-Control/Non-Affiliate Investments” are generally defined as investments that are neither “Control Investments” nor “Affiliate Investments.”

Under the 1940 Act, a BDC must meet certain requirements, including investing at least 70% of our assets in qualifying assets. As of September 30, 2018 , the Company has 83.7% of our assets in qualifying assets. The principal categories of qualifying assets relevant to our business are:

(1) Securities purchased in transactions not involving any public offering from the issuer of such securities, which issuer (subject to certain limited exceptions) is an eligible portfolio company, or from any person who is, or has been during the preceding 13 months, an affiliated person of an eligible portfolio company, or from any other person, subject to such rules as may be prescribed by the Securities and Exchange Commission ("SEC").

(2) Securities of any eligible portfolio company that we control.

(3) Securities purchased in a private transaction from a U.S. issuer that is not an investment company or from an affiliated person of the issuer, or in transactions incident thereto, if the issuer is in bankruptcy and subject to reorganization or if the issuer, immediately prior to the purchase of its securities was unable to meet its obligations as they came due without material assistance other than conventional lending or financing arrangements.

(4) Securities of an eligible portfolio company purchased from any person in a private transaction if there is no readily available market for such securities and we already own 60% of the outstanding equity of the eligible portfolio company.

(5) Securities received in exchange for or distributed on or with respect to securities described in (1) through (4) above, or pursuant to the exercise of warrants or rights relating to such securities.

(6) Cash, cash equivalents, U.S. government securities or high-quality debt securities maturing in one year or less from the time of investment.

Additionally, in order to qualify as a RIC for U.S. federal income tax purposes, we must, among other things meet the following tests:

(1) Continue to maintain our election as a BDC under the 1940 Act at all times during each taxable year.

Table of Contents

(2) Derive in each taxable year at least 90% of our gross income from dividends, interest, payments with respect to certain securities, loans, gains from the sale of stock or other securities, net income from certain "qualified publicly traded partnerships," or other income derived with respect to our business of investing in such stock or securities (the "90% Income Test").

(3) Diversify our holdings in accordance with two Diversification Tests: (a) Diversify our holdings such that at the end of each quarter of the taxable year at least 50% of the value of our assets consists of cash, cash equivalents, U.S. Government securities, securities of other RICs, and such other securities if such other securities of any one issuer do not represent more than 5% of the value of our assets or more than 10% of the outstanding voting securities of the issuer; and (b) Diversify our holdings such that no more than 25% of the value of our assets is invested in the securities, other than U.S. government securities or securities of other RICs, (i) of one issuer, (ii) of two or more issuers that are controlled, as determined under applicable Code rules, by us and that are engaged in the same or similar or related trades or businesses or (iii) of certain "qualified publicly traded partnerships" (collectively, the "Diversification Tests").

The two Diversification Tests must be satisfied quarterly. If a RIC satisfies the tests for one quarter, and then, due solely to fluctuations in market value, fails to meet one of the tests in the next quarter, it retains RIC status. A RIC that fails to meet the Diversification Tests as a result of a nonqualified acquisition may be subject to excess taxes unless the nonqualified acquisition is disposed of and the tests are satisfied within 30 days of the close of the quarter in which the tests are failed.

For the quarter ended September 30, 2018 , we satisfied all RIC tests and have 17.3% in nonqualified assets according to measurement criteria established in Section 851(d) of the Code.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed in the preparation of the consolidated financial statements of CSWC.

Fair Value Measurements We account for substantially all of our financial instruments at fair value in accordance with ASC Topic 820 – Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value, establishes a framework used to measure fair value and requires disclosures for fair value measurements, including the categorization of financial instruments into a three-level hierarchy based on the transparency of valuation inputs. ASC 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. We believe that the carrying amounts of our financial instruments such as cash, receivables and payables approximate the fair value of these items due to the short maturity of these instruments. This is considered a Level 1 valuation technique. The carrying value of our credit facility approximates fair value (Level 3 input). See Note 4 below for further discussion regarding the fair value measurements and hierarchy.

Investments Investments are stated at fair value and are reviewed and approved by our Board of Directors as described in the Notes to the Consolidated Schedule of Investments and Notes 3 and 4 below. Investments are recorded on a trade date basis.

Net Realized Gains or Losses and Net Change in Unrealized Appreciation or Depreciation Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption of an investment or a financial instrument and the cost basis of the investment or financial instrument, without regard to unrealized appreciation or depreciation previously recognized, and includes investments written-off during the period net of recoveries and realized gains or losses from in-kind redemptions. Net change in unrealized appreciation or depreciation reflects the net change in the fair value of the investment portfolio and financial instruments and the reclassification of any prior period unrealized appreciation or depreciation on exited investments and financial instruments to realized gains or losses.

Cash and Cash Equivalents Cash and cash equivalents, which consist of cash and highly liquid investments with an original maturity of three months or less at the date of purchase, are carried at cost, which approximates fair value. Cash may be held in a money market fund from time to time, which is a Level 1 security. Cash and cash equivalents includes deposits at financial institutions. We deposit our cash balances in financial institutions and, at times, such balances may be in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. At September 30, 2018 and March 31, 2018 , cash balances totaling $9.1 million and $6.8 million , respectively, exceeded FDIC insurance limits, subjecting us to

Table of Contents

risk related to the uninsured balance. All of our cash deposits are held at large established high credit quality financial institutions and management believes that the risk of loss associated with any uninsured balances is remote.

Segment Information We operate and manage our business in a singular segment. As an investment company, we invest in portfolio companies in various industries and geographic areas as discussed in Note 3.

Consolidation As permitted under Regulation S-X and ASC 946, we generally do not consolidate our investment in a portfolio company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to CSWC. Accordingly, we consolidated the results of CSWC’s wholly-owned Taxable Subsidiary and CSWC’s wholly-owned management company, CSMC. All intercompany balances have been eliminated upon consolidation.

Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. We have identified investment valuation and revenue recognition as our most critical accounting estimates.

Interest and Dividend Income Interest and dividend income is recorded on an accrual basis to the extent amounts are expected to be collected. Dividend income is recognized on the date dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a distribution. Discounts/premiums received to par on loans purchased are capitalized and accreted or amortized into income over the life of the loan using the effective interest method. In accordance with our valuation policy, accrued interest and dividend income is evaluated quarterly for collectability. When we do not expect the debtor to be able to service all of its debt or other obligations, we will generally establish a reserve against interest income receivable, thereby placing the loan or debt security on non-accrual status, and cease to recognize interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security’s status significantly improves regarding its ability to service debt or other obligations, it will be restored to accrual basis. As of September 30, 2018 and March 31, 2018 , we did not have any investments on non-accrual status or past due its contractual payment obligation.

To maintain RIC tax treatment, non-cash sources of income such as accretion of interest income may need to be paid out to shareholders in the form of distributions, even though CSWC may not have collected the interest income. For the three and six months ended September 30, 2018 , approximately 3.0% and 2.9% , respectively, of CSWC’s total investment income was attributable to non-cash interest income for the accretion of discounts associated with debt investments, net of any premium reduction. For the three and six months ended September 30, 2017 , approximately 2.3% and 2.4% , respectively, of CSWC's total investment income was attributable to non-cash interest income for the accretion of discounts associated with debt investments, net of any premium reduction.

Payment-in-Kind Interest The Company currently holds, and expects to hold in the future, some investments in its portfolio that contain payment-in-kind (“PIK”) interest and dividend provisions. The PIK interest and dividends, computed at the contractual rate specified in each loan agreement, are added to the principal balance of the loan, rather than being paid to the Company in cash, and are recorded as interest and dividend income. Thus, the actual collection of PIK interest and dividends may be deferred until the time of debt principal repayment or disposition of the equity investment. PIK interest and dividends, which are non-cash sources of income, are included in the Company’s taxable income and therefore affect the amount the Company is required to distribute to stockholders to maintain its qualification as a RIC for U.S. federal income tax purposes, even though the Company has not yet collected the cash. Generally, when current cash interest and/or principal payments on a loan become past due, or if the Company otherwise does not expect the borrower to be able to service its debt and other obligations, the Company will place the investment on non-accrual status and will generally cease recognizing PIK interest and dividend income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest and dividend income is deemed to be collectible. The Company writes off any accrued and uncollected PIK interest and dividends when it is determined that the PIK interest and dividends are no longer collectible. As of September 30, 2018 and March 31, 2018 , we did not have any investments on non-accrual status and have not written off any accrued and uncollected PIK interest and dividends. For both the three and six months ended September 30, 2018 , approximately 0.7% of CSWC’s total investment income was attributable to non-cash PIK interest and dividend income. For the three and six months ended September 30,

Table of Contents

2017 , approximately 0.8% and 0.9% , respectively, of CSWC's total investment income was attributable to non-cash PIK interest and dividend income.

Debt Issuance Costs Debt issuance costs include commitment fees and other costs related to CSWC’s senior secured credit facility and its notes (as discussed further in Note 5). The costs in connection with the credit facility have been capitalized and are amortized into interest expense over the term of the credit facility. The costs in connection with the notes are a direct deduction from the related debt liability and amortized into interest expense over the term of the notes.

Federal Income Taxes CSWC has elected and intends to comply with the requirements of the Code necessary to qualify as a RIC. By meeting these requirements, we will not be subject to corporate federal income taxes on ordinary income or capital gains timely distributed to shareholders. In order to qualify as a RIC, the company is required to timely distribute to its shareholders at least 90% of investment company taxable income, as defined by the Code, each year. Investment company taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. Investment company taxable income generally excludes net unrealized appreciation or depreciation, as investment gains and losses are not included in investment company taxable income until they are realized.

Depending on the level of taxable income or capital gains earned in a tax year, we may choose to carry forward taxable income or capital gains in excess of current year distributions into the next year and pay a 4% excise tax on such income. Any such carryover taxable income or capital gains must be distributed through a dividend declared on or prior to the later of (1) the filing of the U.S. federal income tax return for the applicable fiscal year and (2) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated.

In lieu of distributing our net capital gains for a year, we may decide to retain some or all of our net capital gains. We will be required to pay a 21% corporate-level federal income tax on any such retained net capital gains. We may elect to treat such retained capital gain as a deemed distribution to shareholders. Under such circumstances, shareholders will be required to include their share of such retained capital gain in income, but will receive a credit for the amount of corporate-level U.S. federal income tax paid with respect to their shares. As an investment company that qualifies as a RIC, federal income taxes payable on security gains that we elect to retain are accrued only on the last day of our tax year, December 31. Any net capital gains actually distributed to shareholders and properly reported by us as capital gain dividends are generally taxable to the shareholders as long-term capital gains. See Note 6 for further discussion.

CSMC, a wholly-owned subsidiary of CSWC, and the Taxable Subsidiary are not RICs and are required to pay taxes at the corporate rate of 21% as of September 30, 2018 . For tax purposes, CSMC and the Taxable Subsidiary have elected to be treated as taxable entities, and therefore are not consolidated for tax purposes and are taxed at normal corporate tax rates based on taxable income and, as a result of their activities, may generate income tax expense or benefit. The taxable income, or loss, of each of CSMC and the Taxable Subsidiary may differ from its book income, or loss, due to temporary book and tax timing differences and permanent differences. This income tax expense, or benefit, if any, and the related tax assets and liabilities, are reflected in our consolidated financial statements.

Management evaluates tax positions taken or expected to be taken in the course of preparing the Company’s consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the CSWC level not deemed to meet the “more-likely-than-not” threshold would be recorded as an expense in the current year. Management’s conclusions regarding tax positions will be subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof. The Company has concluded that it does not have any uncertain tax positions that meet the recognition of measurement criteria of ASC 740, Income Taxes , ("ASC 740") for the current period. Also, we account for interest and, if applicable, penalties for any uncertain tax positions as a component of income tax expense. No interest or penalties expense was recorded during the three and six months ended September 30, 2018 and 2017 .

Deferred Taxes Deferred tax assets and liabilities are recorded for losses or income at our taxable subsidiaries using statutory tax rates. A valuation allowance is provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. ASC 740 requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation was enacted. See Note 6 for further discussion.

Table of Contents

Stock-Based Compensation We account for our stock-based compensation using the fair value method, as prescribed by ASC Topic 718, Compensation – Stock Compensation . Accordingly, we recognize stock-based compensation cost on a straight-line basis for all share-based payments awards granted to employees. The fair value of stock options are determined on the date of grant using the Black-Scholes pricing model and are expensed over the requisite service period of the related stock options. For restricted stock awards, we measure the grant date fair value based upon the market price of our common stock on the date of the grant. For restricted stock awards, we amortize this fair value to share-based compensation expense over the vesting term. We recognize forfeitures as they occur. We issue new shares upon the exercise of stock options. The unvested shares of restricted stock awarded pursuant to CSWC’s equity compensation plans are participating securities and are included in the basic and diluted earnings per share calculation. On October 26, 2010, we received an exemptive order from the SEC permitting us to issue restricted stock to our executive officers and certain key employees (the “Original Order”). On August 22, 2017, we received an exemptive order that supersedes the Original Order (the “Exemptive Order”) and, in addition to the relief granted under the Original Order, allows us to withhold shares to satisfy tax withholding obligations related to the vesting of restricted stock granted pursuant to the 2010 Restricted Stock Award Plan (the “2010 Plan”) and to pay the exercise price of options to purchase shares of our common stock granted pursuant to the 2009 Stock Incentive Plan (the “2009 Plan”).

At the three and six months ended September 30, 2018 , weighted-average basic shares were adjusted for the dilutive effect of stock-based awards of 4,739 and 4,473 , respectively. At the three and six months ended September 30, 2017 , weighted-average basic shares were adjusted for the dilutive effect of stock-based awards of 67,606 and 65,225 , respectively. For individual cash incentive awards, the option value of the individual cash incentive awards is calculated based on the changes in net asset value (“NAV”) of our Company. In connection with the Share Distribution, we entered into an Employee Matters Agreement (the “Employee Matters Agreement”) with CSW Industrials, Inc. (“CSWI”). Under the Employee Matters Agreement, the value of individual cash incentive awards was determined based upon the NAV of CSWC as of June 30, 2015. See Note 9 for further discussion.

Shareholder Distributions Distributions to common shareholders are recorded on the ex-dividend date. The amount of distributions, if any, is determined by the Board of Directors each quarter and is generally based upon the earnings estimated by management. Net realized capital gains, if any, are generally distributed, although the Company may decide to retain such capital gains for investment.

Presentation Presentation of certain amounts in the Consolidated Financial Statements for the prior year comparative consolidated financial statements is updated to conform to the current period presentation.

Recently Issued or Adopted Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases , which requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which affects narrow aspects of the guidance issued in the amendments in ASU 2016-02. The new guidance is effective for annual periods beginning after December 15, 2018, and interim periods therein. Early application is permitted. While we continue to assess the effect of adoption, we currently believe the single change relates to the recognition of a new right-of-use asset and lease liability on our consolidated balance sheet for our office space operating lease. We currently have one operating lease for office space and do not expect a significant change in our leasing activity between now and adoption.

significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. Additionally, the guidance requires improved disclosures as to the nature, amount, timing and uncertainty of revenue that is recognized. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606)—Narrow-Scope Improvements and Practical Expedients . This ASU clarified guidance on assessing collectability, presenting sales tax, measuring noncash consideration, and certain transition matters. The new guidance is effective for the annual reporting period beginning after December 15, 2017, including interim periods within that reporting period. The Company adopted ASU 2014-09 effective April 1, 2018 and determined that its material financial contracts are excluded from the scope of ASU 2014-09. As a result of the scope exception for financial contracts, the Company's management has determined that there were no material changes to the recognition timing and classification of revenues and expenses; additionally, the adoption of ASU 2014-09 did not have a significant impact on pretax income or on the consolidated financial statement disclosures.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), which is intended to reduce the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2017, and interim periods therein. The Company adopted ASU 2016-15 effective April 1, 2018 and the adoption did not have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which changes the fair value measurement disclosure requirements of ASC 820. The key provisions include new, eliminated and modified disclosure requirements. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods therein. Early application is permitted. CSWC is currently evaluating the impact the adoption of this new accounting standard will have on its consolidated financial statements, but the impact of the adoption is not expected to be material.

In August 2018, the SEC issued the Final Rule Release No. 33-10532, Disclosure Update and Simplification , amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. The amendments are intended to facilitate the disclosure of information to investors and simplify compliance. This final rule is effective on November 5, 2018. The Company is currently evaluating the impact of adopting this SEC Release on its consolidated financial statements.

FAIR VALUE MEASUREMENTS

Investment Valuation Process

The valuation process is led by the finance department in conjunction with the investment team. The process includes a monthly review of each investment by our executive officers and investment teams. Recommended valuations of each portfolio security are prepared quarterly by the finance department using updated financial and other operational information collected by the investment teams. Each investment valuation is then subject to review by the executive officers and investment teams. In conjunction with the internal valuation process, we have also engaged multiple independent consulting firms specializing in financial due diligence, valuation, and business advisory services to provide third-party valuation reviews of certain investments. The third-party valuation firms provide a range of values for selected investments, which is presented to CSWC’s executive officers and Board of Directors.

CSWC also uses a standard internal investment rating system in connection with its investment oversight, portfolio management, and investment valuation procedures for its debt portfolio. This system takes into account both quantitative and qualitative factors of the portfolio company and the investments held therein.

Table of Contents

There is no single standard for determining fair value in good faith, as fair value depends upon the specific circumstances of each individual investment. While management believes our valuation methodologies are appropriate and consistent with market participants, the recorded fair values of our investments may differ significantly from fair values that would have been used had an active market for the securities existed. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned. The Board of Directors has the ultimate responsibility for reviewing and approving, in good faith, the fair value of CSWC’s investments in accordance with the 1940 Act.

Fair Value Hierarchy

CSWC has established and documented processes for determining the fair values of portfolio company investments on a recurring basis in accordance with the 1940 Act and ASC 820. As required by ASC 820, when the inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. For example, a Level 3 fair value measurement may include inputs that are observable (Levels 1 and 2) and unobservable (Level 3). Therefore, unrealized appreciation and depreciation related to such investments categorized within the Level 3 tables below may include changes in fair value that are attributable to both observable inputs (Levels 1 and 2) and unobservable inputs (Level 3). CSWC conducts reviews of fair value hierarchy classifications on a quarterly basis. We also use judgment and consider factors specific to the investment in determining the significance of an input to a fair value measurement.

The three levels of valuation inputs established by ASC 820 are as follows:

• Level 1: Investments whose values are based on unadjusted quoted prices in active markets for identical assets or liabilities.

• Level 2: Investments whose values are based on quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

• Level 3: Investments whose values are based on unobservable inputs that are significant to the overall fair value measurement.

As of September 30, 2018 and March 31, 2018 , 100% of the CSWC investment portfolio consisted of debt and equity instruments of privately held companies for which inputs falling within the categories of Level 1 and Level 2 are generally not available. Therefore, CSWC determines the fair value of its investments (excluding investments for which fair value is measured at NAV) in good faith using Level 3 inputs, pursuant to a valuation policy and process that is established by the management of CSWC, with assistance from multiple third-party valuation advisors, which is subsequently approved by our Board of Directors.

Investment Valuation Inputs

ASC 820 defines fair value in terms of the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date excluding transaction costs. Under ASC 820, the fair value measurement also assumes that the transaction to sell an asset occurs in the principal market for the asset or, in the absence of a principal market, the most advantageous market for the asset. The principal market is the market in which the reporting entity would sell or transfer the asset with the greatest volume and level of activity for the asset. In determining the principal market for an asset or liability under ASC 820, it is assumed that the reporting entity has access to the market as of the measurement date.

The Level 3 inputs to CSWC’s valuation process reflect our best estimate of the assumptions that would be used by market participants in pricing the investment in a transaction in the principal or most advantageous market for the asset.

Table of Contents

The fair value determination of each portfolio investment categorized as Level 3 required one or more of the following unobservable inputs:

• Financial information obtained from each portfolio company, including unaudited statements of operations and balance sheets for the most recent period available as compared to budgeted numbers;

• Current and projected financial condition of the portfolio company;

• Current and projected ability of the portfolio company to service its debt obligations;

• Type and amount of collateral, if any, underlying the investment;

• Current financial ratios (e.g., fixed charge coverage ratio, interest coverage ratio and net debt/EBITDA ratio) applicable to the investment;

• Current liquidity of the investment and related financial ratios (e.g., current ratio and quick ratio);

• Indicative dealer quotations from brokers, banks, and other market participants;

• Market yields on other securities of similar risk;

• Pending debt or capital restructuring of the portfolio company;

• Projected operating results of the portfolio company;

• Current information regarding any offers to purchase the investment;

• Current ability of the portfolio company to raise any additional financing as needed;

• Changes in the economic environment which may have a material impact on the operating results of the portfolio company;

• Internal occurrences that may have an impact (both positive and negative) on the operating performance of the portfolio company;

• Qualitative assessment of key management;

• Contractual rights, obligations or restrictions associated with the investment; and

• Other factors deemed relevant.

CSWC uses several different valuation approaches depending on the security type including the Market Approach, the Income Approach, the Enterprise Value Waterfall Approach, and the NAV Valuation Method.

Market Approach

Market Approach is a qualitative and quantitative analysis of the aforementioned unobservable inputs. It is a combination of the Enterprise Value Waterfall Approach and Income Approach as described in detail below. For debt investments recently originated (within a quarterly reporting period) or where the value has not departed significantly from its cost, we generally rely on our cost basis or recent transaction price to determine the fair value, unless a material event has occurred since origination.

Income Approach

In valuing debt securities, CSWC typically uses an Income Approach model, which considers some or all of the factors listed above. Under the Income Approach, CSWC develops an expectation of the yield that a hypothetical market participant would require when purchasing each debt investment (the “Required Market Yield”). The Required Market Yield is calculated in a two-step process. First, using quarterly market data we estimate the current market yield of similar debt securities. Next, based on the factors described above, we modify the current market yield for each security to produce a

Table of Contents

unique Required Market Yield for each of our investments. The resulting Required Market Yield is the significant Level 3 input to the Income Approach model. If, with respect to an investment, the unobservable inputs have not fluctuated significantly from the date the investment was made or have not fluctuated significantly from CSWC’s expectations on the date the investment was made, and there have been no significant fluctuations in the market pricing for such investments, we may conclude that the Required Market Yield for that investment is equal to the stated rate on the investment. In instances where CSWC determines that the Required Market Yield is different from the stated rate on the investment, we discount the contractual cash flows on the debt instrument using the Required Market Yield in order to estimate the fair value of the debt security.

In addition, under the Income Approach, CSWC also determines the appropriateness of the use of third-party broker quotes, if any, as a significant Level 3 input in determining fair value. In determining the appropriateness of the use of third-party broker quotes, CSWC evaluates the level of actual transactions used by the broker to develop the quote, whether the quote was an indicative price or binding offer, the depth and consistency of broker quotes, the source of the broker quotes, and the correlation of changes in broker quotes with underlying performance of the portfolio company and other market indices. To the extent sufficient observable inputs are available to determine fair value, CSWC may use third-party broker quotes or other independent pricing to determine the fair value of certain debt investments.

Fair value measurements using the Income Approach model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in the Required Market Yield for a particular debt security may result in a lower (higher) fair value for that security. A significant increase (decrease) in a third-party broker quote for a particular debt security may result in a higher (lower) value for that security.

Enterprise Value Waterfall Approach

In valuing equity securities (including warrants), CSWC estimates fair value using an Enterprise Value Waterfall valuation model. CSWC estimates the enterprise value of a portfolio company and then allocates the enterprise value to the portfolio company’s securities in order of their relative liquidation preference. In addition, CSWC assumes that any outstanding debt or other securities that are senior to CSWC’s equity securities are required to be repaid at par. Additionally, we may estimate the fair value of non-performing debt securities using the Enterprise Value Waterfall approach as needed.

To estimate the enterprise value of the portfolio company, CSWC uses a weighted valuation model based on public comparable companies, observable transactions and discounted cash flow analyses. A main input into the valuation model is a measure of the portfolio company’s financial performance, which generally is either earnings before interest, taxes, depreciation and amortization, as adjusted (“Adjusted EBITDA”) or revenues. In addition, we consider other factors, including but not limited to (1) offers from third parties to purchase the portfolio company and (2) the implied value of recent investments in the equity securities of the portfolio company. For certain non-performing assets, we may utilize the liquidation or collateral value of the portfolio company's assets in our estimation of its enterprise value.

The significant Level 3 inputs to the Enterprise Value Waterfall model are (1) an appropriate multiple derived from the comparable public companies and transactions, (2) discount rate assumptions used in the discounted cash flow model and (3) a measure of the portfolio company’s financial performance, which generally is either Adjusted EBITDA or revenues. Inputs can be based on historical operating results, projections of future operating results or a combination thereof. The operating results of a portfolio company may be unaudited, projected or pro forma financial information and may require adjustments for certain non-recurring items. CSWC also may consult with the portfolio company’s senior management to obtain updates on the portfolio company’s performance, including information such as industry trends, new product development, loss of customers and other operational issues. Fair value measurements using the Enterprise Value Waterfall model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in either the multiple, Adjusted EBITDA or revenues for a particular equity security would result in a higher (lower) fair value for that security.

NAV Valuation Method

Under the NAV valuation method, for an investment in an investment fund that does not have a readily determinable fair value, CSWC measures the fair value of the investment predominately based on the NAV of the investment fund as of the measurement date. However, in determining the fair value of the investment, we may consider whether adjustments to the NAV are necessary in certain circumstances, based on the analysis of any restrictions on redemption of our investment as of the measurement date, recent actual sales or redemptions of interests in the investment fund, expected future cash flows available to equity holders, or other uncertainties surrounding CSWC’s ability to realize the full NAV of its interests in the investment fund.

Changes in Fair Value Levels

We monitor the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model based valuation techniques may require the transfer of financial instruments from one fair value level to another. We recognize the transfer of financial instruments between levels at the end of each quarterly reporting period. During the three and six months ended September 30, 2018 and 2017 , we had no transfers between levels.

In accordance with the 1940 Act, with certain limitations, the Company is only allowed to borrow amounts such that its asset coverage (i.e., the ratio of assets less liabilities not represented by senior securities to senior securities such as borrowings), calculated pursuant to the 1940 Act, is at least 200% (or, pursuant to the 1940 Act, 150% if certain requirements are met as described in our Annual Report on Form 10-K in the Business Section under “Regulation as a Business Development Company-Senior Securities”) after such borrowing. On April 25, 2018, the Board of Directors unanimously approved the application of the recently modified asset coverage requirements set forth in Section 61(a)(2) of the 1940 Act. As a result, the minimum asset coverage ratio applicable to the Company will be decreased from 200% to 150%, effective April 25, 2019. The Board of Directors also approved a resolution which limits the Company’s issuance of senior securities such that the asset coverage ratio, taking into account any such issuance, would not be less than 166%, effective April 25, 2019. As of September 30, 2018 , the Company’s asset coverage was 252%.

The Company had the following borrowings outstanding as of September 30, 2018 and March 31, 2018 (amounts in thousands):

Credit Facility	September 30, 2018 — $ 127,000		March 31, 2018 — $ 40,000
December 2022 Notes	75,676		57,500
Less: Unamortized debt issuance costs and debt discount	(2,269	)	(2,195	)
Total Notes	73,407		55,305
Total Borrowings	$ 200,407		$ 95,305

Credit Facility

In August 2016, CSWC entered into a senior secured credit facility (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Facility”) to provide additional liquidity to support its investment and operational activities, which included total commitments of $100 million. The Credit Facility contained an accordion feature that allowed CSWC to increase the total commitments under the facility up to $150 million from new and existing lenders on the same terms and conditions as the existing commitments. In August 2017, we increased our total commitments by $15 million through adding an additional lender using the accordion feature.

On November 16, 2017, CSWC entered into Amendment No. 1 (the “Amendment”) to its Credit Facility. Prior to the Amendment, borrowings under the Credit Facility accrued interest on a per annum basis at a rate equal to the applicable LIBOR rate plus 3.25% with no LIBOR floor. CSWC paid unused commitment fees of 0.50% to 1.50% per annum, based on utilization, on the unused lender commitments under the Credit Facility. The Amendment (1) increased the total borrowing capacity under the Credit Facility to $180 million, with commitments from a diversified group of eight lenders, (2) increased the Credit Facility’s accordion feature that allows for an increase in total commitments of up to $250 million under the Credit Facility from new and existing lenders on the same terms and conditions as the existing commitments, (3) reduced the interest rate on borrowings from LIBOR plus 3.25% down to LIBOR plus 3.00%, with a further step-down to LIBOR plus 2.75% at the time the Company’s net worth exceeds $325 million, (4) reduced unused commitment fees from a utilization-based grid of 0.50% to 1.5% down to a range of 0.50% to 1.0% per annum, and (5) extended the Credit Facility’s revolving period that ended on August 30, 2019 through November 16, 2020. Additionally, the final maturity of the Credit Facility was extended from August 30, 2020 to November 16, 2021. On April 16, 2018 and May 11, 2018, CSWC entered into Incremental Assumption Agreements, which increased the total commitments under the Credit Facility by $20 million and $10 million, respectively. The increases were executed in accordance with the accordion feature of the Credit Facility, increasing total commitments from $180 million to $210 million.

The Credit Facility contains certain affirmative and negative covenants, including but not limited to: (1) certain reporting requirements, (2) maintaining RIC and BDC status, (3) maintaining a minimum shareholders’ equity, (4) maintaining a minimum consolidated net worth, (5) maintaining an asset coverage of not less than 200%, (6) maintaining a consolidated interest coverage ratio of at least 2.5 to 1.0, and (7) at any time the outstanding advances exceed 90% of the borrowing base, maintaining a minimum liquidity of not less than 10% of the covered debt amount.

The Credit Facility also contains customary events of default, including, without limitation, nonpayment, misrepresentation of representations and warranties in a material respect, breach of covenant, bankruptcy, and change of control, with customary cure and notice provisions. If the Company defaults on its obligations under the Credit Facility, the lenders may have the right to foreclose upon and sell, or otherwise transfer, the collateral subject to their security interests. There are no changes to the covenants or the events of default in the Credit Facility as a result of the Amendment.

The Credit Facility is secured by (1) substantially all of the present and future property and assets of the Company and the guarantors and (2) 100% of the equity interests in the Company’s wholly-owned subsidiaries. As of September 30, 2018 , substantially all of the Company’s assets were pledged as collateral for the Credit Facility.

At September 30, 2018 , CSWC had $127.0 million in borrowings outstanding under the Credit Facility. CSWC recognized interest expense related to the Credit Facility, including unused commitment fees and amortization of deferred loan costs of $1.8 million and $3.2 million , respectively, for the three and six months ended September 30, 2018 . For the three and six months ended September 30, 2017 , CSWC recognized interest expense of $0.9 million and $1.6 million , respectively. The weighted average interest rate on the Credit Facility was 5.42% and 5.31% , respectively, for the three and six months ended September 30, 2018 . For the three and six months ended September 30, 2017 , the weighted average interest rate on the Credit Facility was 4.76% and 4.65% , respectively. Average borrowings for the three and six months ended September 30, 2018 were $102.5 million and $80.9 million , respectively. For the three and six months ended September 30, 2017 , average borrowings were $49.7 million and $37.4 million , respectively. As of September 30, 2018 , CSWC was in compliance with all financial covenants under the Credit Facility.

Notes

In December 2017, the Company issued $57.5 million in aggregate principal amount, including the underwriters’ full exercise of their option to purchase additional principal amounts to cover over-allotments, of 5.95% Notes due 2022 (the “December 2022 Notes”). The December 2022 Notes mature on December 15, 2022 and may be redeemed in whole or in part at any time, or from time to time, at the Company’s option on or after December 15, 2019. The December 2022 Notes bear interest at a rate of 5.95% per year, payable quarterly on March 15, June 15, September 15 and December 15 of each year, beginning on March 15, 2018. The December 2022 Notes are an unsecured obligation, rank pari passu with our other outstanding and future unsecured unsubordinated indebtedness and are effectively subordinated to all of our existing and future secured indebtedness, including borrowings under our Credit Facility.

On June 11, 2018, the Company entered into an "At-The-Market" ("ATM") debt distribution agreement, pursuant to which it may offer for sale, from time to time, up to $50 million in aggregate principal amount of December 2022 Notes through B. Riley FBR, Inc., acting as its sales agent (the “2022 Notes Agent”). Sales of the December 2022 Notes may be made in negotiated transactions or transactions that are deemed to be "at the market offerings" as defined in Rule 415 under the Securities Act of 1933, as amended, including sales made directly on The Nasdaq Global Select Market, or similar securities exchanges or sales made through a market maker other than on an exchange at prices related to prevailing market prices or at negotiated prices.

The 2022 Notes Agent receives a commission from the Company equal to up to 2% of the gross sales of any December 2022 Notes sold through the 2022 Notes Agent under the debt distribution agreement. The 2022 Notes Agent is not required to sell any specific principal amount of December 2022 Notes, but will use its commercially reasonable efforts consistent with its sales and trading practices to sell the December 2022 Notes. The December 2022 Notes trade “flat,” which means that purchasers in the secondary market will not pay, and sellers will not receive, any accrued and unpaid interest on the December 2022 Notes that is not reflected in the trading price.

During the six months ended September 30, 2018 , the Company sold 727,063 December 2022 Notes for an aggregate principal amount of approximately $18.2 million at a weighted average effective yield of 5.86%. As of September 30, 2018 , an aggregate principal amount of approximately $31.8 million remains available for issuance and sale under the debt distribution agreement.

All issuances of December 2022 Notes rank equally in right of payment and form a single series of notes.

Table of Contents

As of September 30, 2018 , the carrying amount of the December 2022 Notes was $73.4 million on an aggregate principal amount of $75.7 million at a weighted average effective yield of 5.93%. As of September 30, 2018 , the fair value of the December 2022 Notes was $77.0 million . The fair value is based on the closing price of the security on The Nasdaq Global Select Market, which is a Level 1 input under ASC 820. The Company recognized interest expense related to the December 2022 Notes, including amortization of deferred issuance costs, of $1.2 million and $2.2 million , respectively, for the three and six months ended September 30, 2018 . Average borrowings for the three and six months ended September 30, 2018 were $68.6 million and $63.2 million, respectively.

The indenture governing the December 2022 Notes contains certain covenants including but not limited to (i) a requirement that the Company comply with the asset coverage requirement of Section 61 of the 1940 Act or any successor provisions thereto, after giving effect to any exemptive relief granted to the Company by the SEC, (ii) a requirement, subject to limited exception, that the Company will not declare any cash dividend, or declare any other cash distribution, upon a class of its capital stock, or purchase any such capital stock, unless, in every such case, at the time of the declaration of any such dividend or distribution, or at the time of any such purchase, the Company has the minimum asset coverage required pursuant to Section 61 of the 1940 Act, or any successor provision thereto, after deducting the amount of such dividend, distribution or purchase price, as the case may be, giving effect to any exemptive relief granted to the Company by the SEC and (iii) a requirement to provide financial information to the holders of the December 2022 Notes and the trustee under the indenture if the Company should no longer be subject to the reporting requirements under the Securities Exchange Act of 1934, as amended, (the "Exchange Act"). The indenture and supplement relating to the December 2022 Notes also provides for customary events of default. As of September 30, 2018 , the Company was in compliance with all covenants of the December 2022 Notes.

INCOME TAXES

We have elected to be treated as a RIC under Subchapter M of the Code and have a tax year end of December 31. In order to qualify as a RIC, we must annually distribute at least 90% of our investment company taxable income, as defined by the Code, to our shareholders in a timely manner. Investment company income generally includes net short-term capital gains but excludes net long-term capital gains. A RIC is not subject to federal income tax on the portion of its ordinary income and capital gains that is distributed to its shareholders, including “deemed distributions” as discussed below. A s part of maintaining RIC status, undistributed taxable income and capital gain, which is subject to a 4% non-deductible U.S. federal excise tax, pertaining to a given fiscal year may be distributed up to 12 months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of (1) the filing of the U.S. federal income tax return for the applicable fiscal year and (2) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated. We intend to distribute to our stockholders, after consideration and application of our ability under the Code to carry forward certain excess undistributed taxable income from one tax year into the next tax year, substantially all of our taxable income.

As of September 30, 2018 , CSWC qualified to be taxed as a RIC. We intend to meet the applicable qualifications to be taxed as a RIC in future periods. However, the Company’s ability to meet certain portfolio diversification requirements of RICs in future years may not be controllable by the Company.

The determination of the tax attributes for CSWC’s distributions is made annually, based upon its taxable income for the full year and distributions paid for the full year. Therefore, any determination made on an interim basis is forward-looking based on currently available facts, rules and assumptions and may not be representative of the actual tax attributes of distributions for a full year.

During the quarter ended March 31, 2018 , CSWC declared regular dividends in the amount of $4.5 million, or $0.28 per share. During the quarter ended June 30, 2018 , CSWC declared total dividends of $14.5 million, or $0.89 per share, which consisted of regular dividends in the amount of $4.7 million, or $0.29 per share, and supplemental dividends in the amount of $9.8 million, or $0.60 per share. During the quarter ended September 30, 2018 , CSWC declared total dividends of $7.2 million, or $0.44 per share, which consisted of regular dividends in the amount of $5.6 million, or $0.34 per share, and supplemental dividends in the amount of $1.6 million, or $0.10 per share.

Ordinary dividend distributions from a RIC do not qualify for the 20% maximum tax rate on dividend income from domestic corporations and qualified foreign corporations, except to the extent that the RIC received the income in the

Table of Contents

form of qualifying dividends from domestic corporations and qualified foreign corporations. The tax attributes for distributions will generally include both ordinary income and capital gains, but may also include qualified dividends or return of capital.

The following reconciles net increase in assets resulting from operations to estimated RIC taxable income for the six months ended September 30, 2018 and 2017 :

Reconciliation of RIC Taxable Income 1	Six Months Ended September 30, — 2018	2017
Net increase in net assets from operations	$ 18,241	$ 14,087
Net change in unrealized appreciation on investments	10,835	(5,880	)
Income/gain (expense/loss) recognized for tax on pass-through entities	125	1,852
Loss recognized for tax on dispositions	434	—
Net operating loss - management company and taxable subsidiary	33	468
Non-deductible tax expense	393	(31	)
Estimated taxable income before deductions for distributions	$ 30,061	$ 10,496

1 The calculation of taxable income for each period is an estimate and will not be finally determined until the Company files its tax return each year. Final taxable income may be different than this estimate.

A RIC may elect to retain all or a portion of its net capital gains by designating them as a “deemed distribution” to its shareholders and paying a federal tax on the net capital gains for the benefit of its shareholders. Shareholders then report their share of the retained capital gains on their income tax returns as if it had been received and report a tax credit for tax paid on their behalf by the RIC. Shareholders then add the amount of the “deemed distribution” net of such tax to the basis of their shares. As a result of the tax reform legislation enacted on December 22, 2017 (the "Tax Reform"), the federal tax rate for deemed distributions is 21% as of January 1, 2018. For the tax year ended December 31, 2017, we distributed all long-term capital gains and therefore had no deemed distributions to our shareholders or federal taxes incurred related to such items. "Deemed distributions" are generally reclassified from accumulated net realized gains into additional capital after our tax year ends each December 31.

CSMC, a wholly-owned subsidiary of CSWC, is not a RIC and is required to pay taxes at the current corporate rate. For tax purposes, CSMC has elected to be treated as a taxable entity, and therefore is not consolidated for tax purposes and is taxed at normal corporate tax rates based on its taxable income and, as a result of its activities, may generate income tax expense or benefit. The taxable income, or loss, of CSMC may differ from its book income, or loss, due to temporary book and tax timing differences and permanent differences. This income tax expense, or benefit, if any, and the related tax assets and liabilities, are reflected in our consolidated financial statements. CSMC records individual cash incentive award and bonus accruals on a quarterly basis. Deferred taxes related to the changes in the restoration plan, individual cash incentive award and bonus accruals are also recorded on a quarterly basis. A valuation allowance is provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. Establishing a valuation allowance of a deferred tax asset requires management to make estimates related to expectations of future taxable income. Estimates of future taxable income are based on forecasted cash flows from CSMC’s operations. As of both September 30, 2018 and March 31, 2018 , CSMC had a deferred tax asset of approximately $2.1 million . As of September 30, 2018 , we believe that we will be able to utilize all $2.1 million of our deferred tax assets. We will continue to assess our ability to realize our existing deferred tax assets.

Based on our assessment of our unrecognized tax benefits, management believes that all benefits will be realized and they do not contain any uncertain tax positions. As a result of the Tax Reform, the corporate tax rate of CSMC is 21% as of January 1, 2018.

In addition, we have a wholly-owned taxable subsidiary, or the Taxable Subsidiary, which holds a portion of one or more of our portfolio investments that are listed on the Consolidated Schedule of Investments. The Taxable Subsidiary is consolidated for financial reporting purposes in accordance with U.S. GAAP, so that our consolidated financial statements reflect our investments in the portfolio companies owned by the Taxable Subsidiary. The purpose of the Taxable Subsidiary

Table of Contents

is to permit us to hold certain interests in portfolio companies that are organized as limited liability companies, or LLCs (or other forms of pass-through entities) and still satisfy the RIC tax requirement that at least 90% of our gross income for federal income tax purposes must consist of qualifying investment income. Absent the Taxable Subsidiary, a proportionate amount of any gross income of a partnership or LLC (or other pass-through entity) portfolio investment would flow through directly to us. To the extent that our income did not consist of investment income, it could jeopardize our ability to qualify as a RIC and therefore cause us to incur significant amounts of corporate-level U.S. federal income taxes. Where interests in LLCs (or other pass-through entities) are owned by the Taxable Subsidiary, however, the income from those interests is taxed to the Taxable Subsidiary and does not flow through to us, thereby helping us preserve our RIC status and resultant tax advantages. The Taxable Subsidiary is not consolidated for U.S. federal income tax purposes and may generate income tax expense as a result of their ownership of the portfolio companies. The income tax expense, or benefit, and the related tax assets and liabilities, if any, are reflected in our Statement of Operations. As a result of the Tax Reform, the corporate tax rate of the Taxable Subsidiary is 21% as of January 1, 2018.

The income tax expense, or benefit, and the related tax assets and liabilities, generated by CSWC, CSMC and the Taxable Subsidiary, if any, are reflected in CSWC’s consolidated financial statements. For the three months ended September 30, 2018 , we recognized net income tax expense of $0.3 million , principally consisting of a provision for current U.S. federal income taxes of $0.1 million and a $0.2 million accrual for excise tax on our estimated undistributed taxable income. For the six months ended September 30, 2018 , we recognized net income tax expense of $0.6 million , principally consisting of a provision for current U.S. federal income taxes of $0.2 million and a $0.4 million accrual for excise tax on our estimated undistributed taxable income. For the three months ended September 30, 2017 , we recognized a net income tax expense of $0.1 million , principally consisting of a provision for current U.S. federal income taxes of $0.1 million, a $0.1 million accrual for excise tax on our estimated undistributed taxable income, and a $0.1 million benefit relating to the Taxable Subsidiary. For the six months ended September 30, 2017 , we recognized a net income tax expense of $0.3 million , principally consisting of a provision for current U.S. federal income taxes of $0.3 million .

Regarding the Tax Reform, the Company has completed all accounting and there are no items reported as provisional amounts. However, changes in interpretations, assumptions, and guidance regarding the new tax legislation, as well as the potential for technical corrections to the Tax Reform, could have a material impact on the Company's effective tax rate in future periods. Finally, given the significant complexity of the Tax Reform, current guidance from the U.S. Treasury about implementing the Tax Act and any related guidance from the SEC or the FASB may change, which may require us to refine the Company's estimates in the future.

Although we believe our tax returns are correct, the final determination of tax examinations could be different from what was reported on the returns. In our opinion, we have made adequate tax provisions for years subject to examination. Generally, we are currently open to audit under the statute of limitations by the Internal Revenue Service as well as state taxing authorities for the years ended December 31, 2014 through December 31, 2017.

SHAREHOLDERS' EQUITY

There were no sales of the Company’s equity securities for the six months ended September 30, 2018 and 2017 .

On October 26, 2010, we received an exemptive order from the SEC permitting us to issue restricted stock to our executive officers and certain key employees, or the Original Order. On August 22, 2017, we received the Exemptive Order that supersedes the Original Order and in addition to the relief granted under the Original Order, allows us to withhold shares to satisfy tax withholding obligations related to the vesting of restricted stock granted pursuant to the 2010 Restricted Stock Award Plan, or the 2010 Plan, and to pay the exercise price of options to purchase shares of our common stock granted pursuant to the 2009 Stock Incentive Plan, or the 2009 Plan. During both the six months ended September 30, 2018 and 2017 , the Company did not repurchase any shares in connection with the vesting of restricted stock awards.

Share Repurchase Program

In January 2016, the Company’s Board of Directors approved a share repurchase program authorizing the Company to repurchase up to $10 million of its outstanding common stock in the open market at certain thresholds below its NAV per share, in accordance with guidelines specified in Rules 10b5-1(c)(1)(i)(B) and 10b-18 under the Exchange Act. On March 1, 2016, the Company entered into a share repurchase agreement, which became effective immediately and shall terminate on the earliest of: (1) the date on which a total of $10 million worth of common shares have been purchased under the plan; (2) the date on which the terms set forth in the purchase instructions have been met; or (3) the date that is one trading day after the date on which insider notifies broker in writing that this agreement shall terminate.

During both the six months ended September 30, 2018 and 2017 , the Company did not repurchase any shares of the Company’s common stock under the share repurchase program. As of September 30, 2018 , the Company has approximately $9.4 million available for additional repurchases under the program.

SPIN-OFF COMPENSATION PLAN

On August 28, 2014, CSWC's Board of Directors adopted a compensation plan (the “Spin-off Compensation Plan”) consisting of grants of nonqualified stock options, restricted stock and cash incentive awards to certain officers of the Company at the time. The Spin-off Compensation Plan was intended to align the compensation of the Company’s key officers with the Company’s strategic objective of increasing the market value of the Company’s shares through a transformative transaction for the benefit of the Company’s shareholders. Under the Spin-off Compensation Plan, Joseph B. Armes, former Chief Executive Officer of the Company, Kelly Tacke, former Chief Financial Officer of the Company, and Bowen S. Diehl, former Chief Investment Officer and current Chief Executive Officer of the Company, were collectively as a group eligible to receive an amount equal to six percent of the aggregate appreciation in the Company’s share price from August 28, 2014 (using a base price of $36.16 per share) to the date 90 days after the completion of a transformative transaction (the “Trigger Event Date”). The first plan component consisted of nonqualified options awarded to purchase an aggregate of 259,000 shares of common stock at an exercise price of $36.60 per share. The second plan component consisted of an aggregate of 127,000 shares of restricted stock, which have voting rights but do not have cash dividend rights. See Note 9 for further discussion on the first two components of the Spin-off Compensation Plan. The final plan component consisted of cash incentive payments awarded to each participant in an amount equal to the excess of each awardee’s allocable portion of the total payment amount over the aggregate value as of the Trigger Event Date of the awardee’s restricted common stock and nonqualified options awarded under the plan.

On September 8, 2015, the Board designated the Share Distribution as a transformative transaction for purposes of the Spin-off Compensation Plan and amended the award agreements granted under the plan to provide for accelerated vesting of the awards held by a participant in the event of a termination of that participant’s service effected by the participant for good reason, by the employer without cause, or as a result of the disability or death of the participant. On September 30, 2015, we completed the Share Distribution.

Effective immediately with the Share Distribution, both Joseph B. Armes and Kelly Tacke became employees of CSWI and Bowen Diehl, our President and Chief Executive Officer, continued to be an employee of our Company. The Company entered into the Employee Matters Agreement with CSWI . Under the Employee Matters Agreement, we retained the cash incentive awards granted under the Spin-off Compensation Plan, and all liabilities with respect to the cash incentive

Table of Contents

awards remained liabilities of CSWC. The equity based awards vesting terms were as follows: (1) one-third on December 29, 2015; (2) one-third on December 29, 2016; and (3) one-third on December 29, 2017, subject to accelerated vesting as described above.

The total value accretion was six percent of the aggregate appreciation in the Company’s share price from $36.16 to the combined volume-weighted average prices of both CSWC and CSWI stock as of December 29, 2015. The cash component of the Spin-off Compensation Plan was the difference between the total value accretion and the aggregate value of the awardee’s restricted common stock and non-qualified option awards under the Spin-off Compensation Plan. The total cash liabilities for three participants under the plan totaled $6.1 million. The final payment of $1.4 million was fully vested on December 29, 2017, and was subsequently paid out in January 2018. As of September 30, 2018 , there is no remaining unrecognized expense related to the Spin-off Compensation Plan.

During the three and six months ended September 30, 2018 , we did not recognize any expense related to the Spin-off Compensation Plan. During the three and six months ended September 30, 2017 , we recognized the cash component of spin-off compensation expense of $0.2 million and $0.3 million , respectively, which represented the cash component of spin-off compensation for our current employee. During the three and six months ended September 30, 2017 , we also recorded $0.2 million and $0.3 million , respectively, directly to additional capital for the cash component of the spin-off compensation related to one of the two employees who transferred to CSWI.

EMPLOYEE STOCK BASED COMPENSATION PLANS

Stock Awards

Pursuant to the Capital Southwest Corporation 2010 Plan, our Board of Directors originally reserved 188,000 shares of restricted stock for issuance to certain of our employees. At our annual shareholder meetings in August 2015 and August 2018, our shareholders approved an increase of an additional 450,000 and 850,000 shares, respectively, to our 2010 Plan. A restricted stock award is an award of shares of our common stock, which generally have full voting and dividend rights but are restricted with regard to sale or transfer. Restricted stock awards are independent of stock grants and are generally subject to forfeiture if employment terminates prior to these restrictions lapsing. Unless otherwise specified in the award agreement, these shares vest in equal annual installments over a four- to five-year period from the grant date and are expensed over the vesting period starting on the grant date.

On August 28, 2014, our Board of Directors amended the 2010 Plan, as permitted pursuant to Section 14 of the 2010 Plan (the “First Amendment to the 2010 Plan”). The First Amendment to the 2010 Plan provides that an award agreement may allow an award to remain outstanding after a spin-off or change in control of one or more wholly-owned subsidiaries of the Company. In addition, on August 28, 2014, the Board of Directors granted 127,000 shares of restricted stock under the Spin-off Compensation Plan. On August 10, 2015, the Second Amendment to the 2010 Plan increased the number of shares of Company common stock available for issuance by 450,000 shares.

On September 30, 2015, we completed the Share Distribution. Each holder of an outstanding Capital Southwest Restricted Stock Award immediately prior to the Share Distribution received, as of the effective date of the Share Distribution, a CSWI Restricted Stock Award for the number of CSWI Shares the holder would have received if the outstanding Capital Southwest Restricted Stock Award was comprised of fully vested Capital Southwest Shares as of the effective date.

The vesting terms for restricted stock awards previously granted under the Spin-off Compensation Plan are as follows: (1) one-third on December 29, 2015; (2) one-third on December 29, 2016; and (3) one-third on December 29, 2017, subject to accelerated vesting as described above. As of September 30, 2018 , there is no remaining unrecognized expense related to the Spin-off Compensation Plan.

On August 22, 2017, we received the Exemptive Order from the SEC that supersedes the Original Order and, in addition to the relief granted under the Original Order, allows the Company to withhold shares to satisfy tax withholding obligations related to the vesting of restricted stock granted pursuant to the 2010 Plan. The Third Amendment to the 2010 Plan, which became effective on August 22, 2017, reflects amendments relating to the Exemptive Order.

Table of Contents

On August 2, 2018, the Fourth Amendment to the 2010 Plan increased the number of shares of Company common stock available for issuance by 850,000 shares. The Fourth Amendment also includes revisions regarding change in control provisions, minimum vesting periods, incorporation of a clawback policy and other technical revisions.

The following table summarizes the restricted stock available for issuance for the six months ended September 30, 2018 :

We expense the cost of the restricted stock awards, which is determined to equal the fair value of the restricted stock award at the date of grant on a straight-line basis over the requisite service period. For these purposes, the fair value of the restricted stock award is determined based upon the closing price of our common stock on the date of the grant. Due to the Share Distribution, the Company evaluated (1) the value of the CSWC stock awards prior to the Share Distribution and (2) the combined value of CSWC and CSWI stock awards following the Share Distribution and recorded additional incremental stock based compensation expenses.

For the three months ended September 30, 2018 and 2017 , we recognized total share based compensation expense of $0.4 million and $0.4 million , respectively, related to the restricted stock issued to our employees and officers. For the six months ended September 30, 2018 and 2017 , we recognized total share based compensation expense of $0.9 million and $0.7 million , respectively, related to the restricted stock issued to our employees and officers.

As of September 30, 2018 , the total remaining unrecognized compensation expense related to non-vested restricted stock awards was $4.2 million, which will be amortized over the weighted-average vesting period of approximately 2.4 years. Subsequent to the Share Distribution, the compensation expense related to non-vested awards held by employees who are now employed by CSWI is recorded by CSWI.

The following table summarizes the restricted stock outstanding as of September 30, 2018 :

Stock Options

On July 20, 2009, shareholders approved the 2009 Plan, which provides for the granting of stock options to employees and officers and authorizes the issuance of common stock upon exercise of stock options for up to 560,000 shares. All options are granted at or above market price, generally expire up to 10 years from the date of grant and are generally exercisable on or after the first anniversary of the date of grant in five annual installments.

On August 28, 2014, our Board of Directors amended the 2009 Plan, as permitted pursuant to Section 18 of the 2009 Plan (the “First Amendment to the 2009 Plan”). The First Amendment to the 2009 Plan provides that an award agreement may allow an award to remain outstanding after a spin-off or change in control of one or more wholly-owned subsidiaries

of the Company. In addition, on August 28, 2014, options to purchase 259,000 shares at $36.60 per share were granted under the 2009 Plan, as amended. On September 8, 2015, the Board designated the Share Distribution as a transformative transaction for purposes of the 2009 Plan and amended the award agreements granted under the 2009 Plan to provide for accelerated vesting of the awards held by a participant in the event of a termination of that participant’s service effected by the participant for good reason, by the employer without cause, or as a result of the disability or death of the participant. A third of these options were vested on each of December 29, 2015, December 29, 2016 and December 29, 2017, respectively, subject to accelerated vesting as described above.

At September 30, 2015, in connection with the Share Distribution, we entered into the Employee Matters Agreement, which provided that each option to acquire CSWC common stock that was outstanding immediately prior to September 30, 2015, would be converted into both an option to acquire post-Share Distribution CSWC common stock and an option to acquire CSWI common stock and would be subject to substantially the same terms and conditions (including with respect to vesting and expiration) after the Share Distribution. Certain adjustments, using volumetric weighted-average prices for the 10-day period immediately prior to and immediately following the distribution, were made to the exercise price and number of shares of CSWC subject to such awards, with the intention of preserving the economic value of the awards immediately prior to the distribution for all CSWC employees. We compared the fair market value of our stock options on the day of the Share Distribution with the combined fair value of our stock options and CSWI stock options the day after the completion of the Share Distribution. The distribution-related adjustments did not have an impact on compensation expense for the three and six months ended September 30, 2018 and 2017 .

On August 22, 2017, we received the Exemptive Order from the SEC that supersedes the Original Order and, in addition to the relief granted under the Original Order, allows us to withhold shares of our common stock to satisfy the exercise of options to purchase shares of our common stock granted pursuant to the 2009 Plan.

At September 30, 2018 , there are options to acquire 11,950 shares of common stock outstanding. The Compensation Committee does not intend to grant additional options under the 2009 Plan or request shareholders’ approval of additional stock options to be added under the 2009 Plan.

The following table summarizes activity in the 2009 Plan as of September 30, 2018 , including adjustments in connection with the Share Distribution:

We recognize compensation cost using the straight-line method for all share-based payments. The fair value of stock options are determined on the date of grant using the Black-Scholes pricing model and are expensed over the requisite service period of the related stock options. Accordingly, for the three months ended September 30, 2018 and 2017 , we recognized stock option compensation expense of $10.5 thousand and $48.0 thousand , respectively related to the stock options held by our employees and officers. For the six months ended September 30, 2018 and 2017 , we recognized stock option compensation expense of $21.1 thousand and $0.1 million , respectively, related to the stock options held by our employees and officers. As of September 30, 2018 , the total remaining unrecognized compensation cost related to non-vested stock options was $17.6 thousand, which will be amortized over the weighted-average vesting period of approximately 0.5 years.

At September 30, 2018 , the range of exercise prices was $11.00 to $11.66 and the weighted-average remaining contractual term of outstanding options was 5.1 years. The total number of shares of common stock exercisable under the 2009 Plan at September 30, 2018 was 5,975 shares with a weighted-average exercise price of $11.66. During the quarter ended September 30, 2018 , 5,975 options became exercisable and 50,000 options were exercised with an average exercise price of $11.53 . During the quarter ended September 30, 2017 , 5,975 options became exercisable and no options were exercised.

Individual Incentive Awards

On January 16, 2012, our Board of Directors approved the issuance of 104,000 individual cash incentive awards with a baseline for measuring increases in NAV per share of $36.74 (NAV at December 31, 2011) to provide deferred compensation to certain key employees. Under the individual cash incentive award agreements, awards vest on the fifth anniversary of the award date. Upon exercise of an individual cash incentive award, the Company pays the recipient a cash payment in an amount equal to the NAV per share minus the baseline NAV per share, adjusted for capital gain dividends declared.

In connection with the Share Distribution, we entered into the Employee Matters Agreement with CSWI. Under the Employee Matters Agreement, the individual cash incentive award agreements were amended to provide that the value of each individual cash incentive award was determined based upon the NAV of CSWC as of June 30, 2015. The remaining terms of each individual cash incentive award agreement, including the vesting and payment terms, will remain unchanged. After the effective date of the Share Distribution, CSWC retains all liabilities associated with all individual cash incentive awards granted by CSWC.

There are currently 24,000 individual cash incentive awards outstanding as of September 30, 2018 and the liability for individual cash incentive awards was $0.1 million at September 30, 2018 . During the six months ended September 30, 2018 , payments in the amount of $0.2 million were paid to vested employees. As of September 30, 2018 , there is no remaining unrecognized compensation expense related to individual cash incentive awards.

There were no individual cash incentive awards granted during the six months ended September 30, 2018 .

OTHER EMPLOYEE COMPENSATION

We established a 401(k) plan (“401K Plan”) effective October 1, 2015. All full-time employees are eligible to participate in the 401K Plan. The 401K Plan permits employees to defer a portion of their total annual compensation up to the Internal Revenue Service annual maximum based on age and eligibility. We made contributions to the 401K Plan of up to 4.5% of the Internal Revenue Service’s annual maximum eligible compensation, all of which is fully vested immediately. During the three months ended September 30, 2018 and 2017 , we made matching contributions of approximately $25.2 thousand and $25.7 thousand, respectively. During the six months ended September 30, 2018 and 2017 , we made matching contributions of approximately $87.8 thousand and $78.3 thousand, respectively.

COMMITMENTS AND CONTINGENCIES

Commitments

In the normal course of business, the Company is a party to financial instruments with off-balance sheet risk, consisting primarily of unused commitments to extend financing to the Company’s portfolio companies.

OVERVIEW

We are an internally managed closed-end, non-diversified management investment company that has elected to be regulated as a BDC under the 1940 Act. We specialize in providing customized debt and equity financing to LMM companies and debt capital to UMM companies in a broad range of investment segments located primarily in the United States. Our investment objective is to produce attractive risk-adjusted returns by generating current income from our debt investments and capital appreciation from our equity and equity related investments. Our investment strategy is to partner with business owners, management teams and financial sponsors to provide flexible financing solutions to fund growth, changes of control, or other corporate events. We invest primarily in senior debt securities, secured by security interests in portfolio company assets, and in secured and unsecured subordinated debt securities. We also invest in equity interests in our portfolio companies alongside our debt securities.

We seek to fill the financing gap for LMM companies, which, historically, have had more limited access to financing from commercial banks and other traditional sources. The underserved nature of the LMM creates the opportunity for us to meet the financing needs of LMM companies while also negotiating favorable transaction terms and equity participations. Our ability to invest across a LMM company’s capital structure, from secured loans to equity securities, allows us to offer portfolio companies a comprehensive suite of financing options. Providing customized financing solutions is important to LMM companies. We generally seek to partner directly with financial sponsors, entrepreneurs, management teams and business owners in making our investments. Our LMM debt investments typically include senior loans with a first lien on the assets of the portfolio company, as well as subordinated debt which may either be secured or unsecured subordinated loans. Our LMM debt investments typically have a term of between five and seven years from the original investment date. We also often seek to invest in the equity securities of our LMM portfolio companies.

Our investments in UMM companies primarily consist of direct investments in or secondary purchases of interest bearing debt securities in privately held companies that are generally larger in size than the LMM companies included in our portfolio. Our UMM debt investments are generally secured by either a first or second priority lien on the assets of the

Table of Contents

portfolio company and typically have an expected duration of between three and seven years from the original investment date.

Because we are internally managed, we do not pay any external investment advisory fees, but instead directly incur the operating costs associated with employing investment and portfolio management professionals. We believe that our internally managed structure provides us with a beneficial operating expense structure when compared to other publicly traded and privately held investment firms which are externally managed, and our internally managed structure allows us the opportunity to leverage our non-interest operating expenses as we grow our investment portfolio. For the six months ended September 30, 2018 and 2017 , the ratio of our annualized second quarter operating expenses, excluding interest expense, as a percentage of our quarterly average total assets was 3.05% and 4.03%, respectively.

CRITICAL ACCOUNTING POLICIES AND USE OF ESTIMATES

The preparation of our consolidated financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the periods covered by the consolidated financial statements. We have identified investment valuation and revenue recognition as our most critical accounting estimates. On an on-going basis, we evaluate our estimates, including those related to the matters below. These estimates are based on the information that is currently available to us and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ materially from those estimates under different assumptions or conditions. A discussion of our critical accounting policies follows.

Valuation of Investments

The most significant determination inherent in the preparation of our consolidated financial statements is the valuation of our investment portfolio and the related amounts of unrealized appreciation and depreciation. As of September 30, 2018 and March 31, 2018 , our investment portfolio at fair value represented approximately 95.2% and 94.2%, respectively, of our total assets. We are required to report our investments at fair value. We follow the provisions of Accounting Standards Codification, or ASC 820, Fair Value Measurements and Disclosures ("ASC 820"). ASC 820 defines fair value, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value, and enhances disclosure requirements for fair value measurements. ASC 820 requires us to assume that the portfolio investment is to be sold in the principal market to independent market participants, which may be a hypothetical market. See Note 4 — “Fair Value Measurements” in the notes to consolidated financial statements for a detailed discussion of our investment portfolio valuation process and procedures.

Due to the inherent uncertainty in the valuation process, our determination of fair value for our investment portfolio may differ materially from the values that would have been determined had a ready market for the securities actually existed. In addition, changes in the market environment, portfolio company performance, and other events may occur over the lives of the investments that may cause the gains or losses ultimately realized on these investments to be materially different than the valuations currently assigned. We determine fair value of each individual investment and record changes in fair value as unrealized appreciation or depreciation.

Our Board of Directors is responsible for determining, in good faith, the fair value of our investments and our valuation procedures, consistent with the 1940 Act requirements. Our Board of Directors believes that our investment portfolio as of September 30, 2018 and March 31, 2018 reflects the fair value as of those dates based on the markets in which we operate and other conditions in existence on those reporting dates.

Revenue Recognition

Interest and Dividend Income

Interest and dividend income is recorded on an accrual basis to the extent amounts are expected to be collected. Dividend income is recognized on the date dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a distribution. Discounts/premiums received to par on loans purchased are capitalized and accreted or amortized into income over the life of the loan using the effective interest method. In accordance

Table of Contents

with our valuation policy, accrued interest and dividend income is evaluated quarterly for collectability. When we do not expect the debtor to be able to service all of its debt or other obligations, we will generally establish a reserve against interest income receivable, thereby placing the loan or debt security on non-accrual status, and cease to recognize interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security’s status significantly improves regarding its ability to service debt or other obligations, it will be restored to accrual basis. As of September 30, 2018 , we did not have any investments on non-accrual status or past due its contractual payment obligation.

Recently Issued Accounting Standards

In February 2016, the FASB issued ASU 2016-02, Leases , which requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which affects narrow aspects of the guidance issued in the amendments in ASU 2016-02. The new guidance is effective for annual periods beginning after December 15, 2018, and interim periods therein. Early application is permitted. While we continue to assess the effect of adoption, we currently believe the single change relates to the recognition of a new right-of-use asset and lease liability on our consolidated balance sheet for our office space operating lease. We currently have one operating lease for office space and do not expect a significant change in our leasing activity between now and adoption.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . ASU 2014-09 supersedes the revenue recognition requirements under SAC Topic 605, Revenue Recognition , and most industry-specific guidance throughout the Industry Topics of the ASC. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. Under the new guidance, an entity is required to perform the following five steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The new guidance will significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. Additionally, the guidance requires improved disclosures as to the nature, amount, timing and uncertainty of revenue that is recognized. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606)—Narrow-Scope Improvements and Practical Expedients . This ASU clarified guidance on assessing collectability, presenting sales tax, measuring noncash consideration, and certain transition matters. The new guidance is effective for the annual reporting period beginning after December 15, 2017, including interim periods within that reporting period. The Company adopted ASU 2014-09 effective April 1, 2018 and determined that its material financial contracts are excluded from the scope of ASU 2014-09. As a result of the scope exception for financial contracts, the Company's management has determined that there were no material changes to the recognition timing and classification of revenues and expenses; additionally, the adoption of ASU 2014-09 did not have a significant impact on pretax income or on the consolidated financial statement disclosures.

Portfolio Asset Quality

We utilize an internally developed investment rating system to rate the performance and monitor the expected level of returns for each debt investment in our portfolio. The investment rating system takes into account both quantitative and qualitative factors of the portfolio company and the investments held therein, including each investment's expected level of returns and the collectability of our debt investments, comparisons to competitors and other industry participants and the portfolio company's future outlook. The ratings are not intended to reflect the performance or expected level of returns of our equity investments.

• Investment Rating 1 represents the least amount of risk in our portfolio. The investment is performing materially above underwriting expectations and the trends and risk factors are generally favorable.

• Investment Rating 2 indicates the investment is performing as expected at the time of underwriting and the trends and risk factors are generally favorable to neutral.

• Investment Rating 3 involves an investment performing below underwriting expectations and the trends and risk factors are generally neutral to negative. The portfolio company or investment may be out of compliance with

Table of Contents

financial covenants and interest payments may be impaired, however principal payments are generally not past due.

• Investment Rating 4 indicates that the investment is performing materially below underwriting expectations, the trends and risk factors are generally negative and the risk of the investment has increased substantially. Interest and principal payments on our investment are likely to be impaired.

The following table shows the distribution of our debt portfolio investments on the 1 to 4 investment rating scale at fair value as of September 30, 2018 and March 31, 2018 :

RESULTS OF OPERATIONS

The composite measure of our financial performance in the Consolidated Statements of Operations is captioned “Net increase in net assets from operations” and consists of three elements. The first is “Net investment income,” which is the difference between income from interest, dividends and fees and our combined operating and interest expenses, net of applicable income taxes. The second element is “Net realized gain on investments before income tax,” which is the difference between the proceeds received from the disposition of portfolio securities and their stated cost. The third element is the “Net change in unrealized appreciation of investments, net of tax,” which is the net change in the market or fair value of our investment portfolio, compared with stated cost. It should be noted that the “Net realized gain on investments before income tax” and “Net change in unrealized appreciation of investments, net of tax” are directly related in that when an appreciated portfolio security is sold to realize a gain, a corresponding decrease in net unrealized appreciation occurs by transferring the gain associated with the transaction from being “unrealized” to being “realized.” Conversely, when a loss is realized on a depreciated portfolio security, an increase in net unrealized appreciation occurs.

Investment Income

Total investment income consisted of interest income, management fees, dividend income and other income for each applicable period. For the three months ended September 30, 2018 , Capital Southwest reported investment income of $12.6 million, a $4.1 million , or 48.0% , increase as compared to the three months ended September 30, 2017 . The increase was primarily due to a $4.0 million, or 74.9%, increase in interest income from our debt investments due to a 59.1% increase in the cost basis of our debt investments from $279.8 million to $445.1 million year over year in addition to an increase in the weighted average yield on debt investments from 10.71% to 11.61% year over year.

Operating Expenses

Due to the nature of our business, the majority of our operating expenses are related to interest and fees on our borrowings, employee compensation (including both cash and share-based compensation) and general and administrative expenses.

Interest and Fees on our Borrowings

For the three months ended September 30, 2018 , our total interest expense was $3.1 million , an increase of $2.2 million as compared to the total interest expense of $0.9 million for the three months ended September 30, 2017 . The increase was primarily attributable to an increase of $52.8 million in average borrowings on our Credit Facility during the three months ended September 30, 2018 as compared to the three months ended September 30, 2017 , as well as the issuance of $75.7 million of the December 2022 Notes.

Equity Capital Activities

In January 2016, our board of directors approved a share repurchase program authorizing us to repurchase up to $10 million in the aggregate of our outstanding common stock in the open market at certain thresholds below our net asset value per share, in accordance with Rules 10b-18 under the Exchange Act.

OFF-BALANCE SHEET ARRANGEMENTS

We may be a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of our portfolio companies. These instruments may include commitments to extend credit and fund equity capital and involve, to varying degrees, elements of liquidity and credit risk in excess of the amount recognized in the balance sheet.

At September 30, 2018 and March 31, 2018 , we had a total of approximately $26.9 million and $11.6 million , respectively, in currently unfunded commitments (as discussed in Note 11 to the Consolidated Financial Statements). Included within the total unfunded commitments as of September 30, 2018 were commitments to issue letters of credit through a financial intermediary on behalf of certain portfolio companies. As of September 30, 2018 , we had $3.3 million in letters of credit issued and outstanding under these commitments on behalf of the portfolio companies. For the letters of credit issued and outstanding, we would be required to make payments to third parties if the portfolio companies were to default on their related payment obligations. Of these letters of credit, $3.3 million expire in May 2019. As of September 30, 2018 , none of the letters of credit issued and outstanding were recorded as a liability on the Company's balance sheet as such letters of credit are considered in the valuation of the investments in the portfolio company.

The Company believes its assets will provide adequate coverage to satisfy these commitments. As of September 30, 2018 , the Company had cash and cash equivalents of $10.2 million and $83.0 million in available borrowings under the Credit Facility.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

We are subject to market risk. Market risk includes risk that arise from changes in interest rates, commodity prices, equity prices and other market changes that affect market sensitive instruments. The prices of securities held by us may decline in response to certain events, including those directly involving the companies in which we invest; conditions affecting the general economy; overall market changes; legislative reform; local, regional, national or global political, social or economic instability; and interest rate fluctuations.

Interest Rate Risk

We are subject to interest rate risk. Interest rate risk is defined as the sensitivity of our current and future earnings to interest rate volatility, variability of spread relationships, the difference in re-pricing internals between our assets and liabilities and the effect that interest rates may have on our cash flows. Changes in the general level of interest rates can affect our net interest income, which is the difference between the interest income earned on interest earning assets and our interest expense incurred in connection with our interest-bearing liabilities. Changes in interest rates can also affect, among other things, our ability to acquire and originate loans and securities and the value of our investment portfolio. Our net investment income is affected by fluctuations in various interest rates including LIBOR and prime rates. However, the interest rates on our December 2022 Notes are fixed for the life of such debt. Our risk management systems and procedures are designed to identify and analyze our risk, to set appropriate policies and limits and to continually monitor these risks. We regularly measure exposure to interest rate risk and determine whether or not any hedging transactions are necessary to mitigate exposure to changes in interest rates. As of September 30, 2018 , we were not a party to any hedging arrangements.

As of September 30, 2018 , approximately 93.5% of our debt investment portfolio (at fair value) bore interest at floating rates, 88.4% of which were subject to contractual minimum interest rates. A hypothetical 100 basis point increase in interest rates could increase our net investment income by a maximum of $2.6 million, or $0.16 per share, on an annual basis. A hypothetical 100 basis point decrease in interest rates could decrease our net investment income by a maximum of $2.4 million, or $0.15 per share, on an annual basis. Our Credit Facility bears interest on a per annum basis equal to the applicable LIBOR rate plus 3.00%, with a step-down to LIBOR plus 2.75% at the time the Company’s net worth exceeds $325 million. We pay unused commitment fees of 0.50% to 1.00% per annum, based on utilization.

Although we believe that the foregoing analysis is indicative of our sensitivity to interest rate changes, it does not adjust for potential changes in the credit market, credit quality, size and composition of the assets in our portfolio. It also does not adjust for other business developments, including future borrowings that could affect the net increase in net assets resulting from operations, or net income. It also does not assume any repayments from borrowers. Accordingly, no assurances can be given that actual results would not differ materially from the statement above.

Because we currently borrow, and plan to borrow in the future, money to make investments, our net investment income is dependent upon the difference between the rate at which we borrow funds and the rate at which we invest the funds borrowed. Accordingly, there can be no assurance that a significant change in interest rates will not have a material adverse effect on our net investment income. In periods of rising interest rates, our cost of funds would increase, which could reduce our net investment income if there is not a corresponding increase in interest income generated by our investment portfolio.
