•	Defensive growth industries.  We seek to invest in industries that can succeed in both robust and weak economic environments but which are also sufficiently large and growing to achieve high valuations providing enterprise value cushion for our targeted debt securities.

•	High barriers to competitive entry.  We target industries and companies that have well defined industries and well established, understandable barriers to competitive entry.

•	Recurring revenue.  Where possible, we focus on companies that have a high degree of predictability in future revenue.

---

•	Flexible cost structure.  We seek to invest in businesses that have limited fixed costs and therefore modest operating leverage.

•	Strong free cash flow and high return on assets.  We focus on businesses with a demonstrated ability to produce meaningful free cash flow from operations. We typically target companies that are not asset intensive and that have minimal capital expenditure and minimal working capital growth needs.

•	Sustainable business and niche market dominance.  We seek to invest in businesses that exert niche market dominance in their industry and that have a demonstrated history of sustaining market leadership over time.

•	Established companies.  We seek to invest in established companies with sound historical financial performance. We do not intend to invest in start-up companies or companies with speculative business plans.

•	Private equity sponsorship.  We generally seek to invest in companies in conjunction with private equity sponsors who we know and trust and who have proven capabilities in building value.

•	Seasoned management team.  We generally require that portfolio companies have a seasoned management team with strong corporate governance. Oftentimes we have a historical relationship with or direct knowledge of key managers from previous investment experience.

•	Identifying attractive investment sectors top down;

•	Creating competitive advantages in the selected industry sectors; and

•	Targeting companies with leading market share and attractive business models in its chosen sectors.

First Lien Loans and Bonds.  First lien loans and bonds generally have terms of four to seven years, provide for a variable or fixed interest rate, may contain prepayment penalties and are secured by a first priority security interest in all existing and future assets of the borrower. These first lien loans and bonds may include payment-in-kind ("PIK") interest, which represents contractual interest accrued and added to the principal that generally becomes due at maturity. Our first lien loans may include traditional first lien senior secured loans or unitranche loans. Unitranche loans combine characteristics of traditional first lien senior secured loans as well as second lien and subordinated loans. Unitranche loans will expose us to the risks associated with second lien and subordinated loans to the extent we invest in the “last out” tranche.

•	Second Lien Loans and Bonds.  Second lien loans and bonds generally have terms of five to eight years, provide for a variable or fixed interest rate, may contain prepayment penalties and are secured by a second priority security interest in all existing and future assets of the borrower. These second lien loans and bonds may include PIK interest.

•	Unsecured Senior, Subordinated and "Mezzanine" Loans and Bonds.  Any unsecured investments are generally expected to have terms of five to ten years and provide for a fixed interest rate. Unsecured investments may include PIK interest and may have an equity component, such as warrants to purchase common stock in the portfolio company.

•	ongoing dialogue with and review of original diligence sources;

•	periodic contact with portfolio company management (and, if appropriate, the private equity sponsor) to discuss financial position, requirements and accomplishments; and

•	assessment of business development success, including product development, profitability and the portfolio company's overall adherence to its business plan.

•	Investment Rating 1—Investment is performing materially above expectations;

•	Investment Rating 2—Investment is performing materially in-line with expectations. All new loans are rated 2 at initial purchase;

•	Investment Rating 3—Investment is performing materially below expectations, where the risk of loss has materially increased since the original investment; and

•	Investment Rating 4—Investment is performing substantially below expectations and risks have increased substantially since the original investment. Payments may be delinquent. There is meaningful possibility that we will not recoup our original cost basis in the investment and may realize a substantial loss upon exit.

(1)	Investments for which market quotations are readily available on an exchange are valued at such market quotations based on the closing price indicated from independent pricing services.

(2)	Investments for which indicative prices are obtained from various pricing services and/or brokers or dealers are valued through a multi-step valuation process, as described below, to determine whether the quote(s) obtained is representative of fair value in accordance with GAAP.

a.

Bond quotes are obtained through independent pricing services. Internal reviews are performed by the investment professionals of the Investment Adviser to ensure that the quote obtained is representative of fair value in accordance with GAAP and if so, the quote is used. If the Investment Adviser is unable to sufficiently validate the quote(s) internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below); and

b.	For investments other than bonds, the investment professionals of the Investment Adviser look at the number of quotes readily available and perform the following:

i.	Investments for which two or more quotes are received from a pricing service are valued using the mean of the mean of the bid and ask of the quotes obtained;

ii.

Investments for which one quote is received from a pricing service are validated internally. The investment professionals of the Investment Adviser analyze the market quotes obtained using an array of valuation methods (further described below) to validate the fair value.

•	No incentive fee is payable to the Investment Adviser in any calendar quarter in which our Pre-Incentive Fee Adjusted Net Investment Income does not exceed the hurdle rate of 2.0% (the "preferred return" or "hurdle").

•

100.0% of our Pre-Incentive Fee Adjusted Net Investment Income with respect to that portion of such Pre-Incentive Fee Adjusted Net Investment Income, if any, that exceeds the hurdle rate but is less than or equal to 2.5% in any calendar quarter (10.0% annualized) is payable to the Investment Adviser. This portion of our Pre-Incentive Fee Adjusted Net Investment Income (which exceeds the hurdle rate but is less than or equal to 2.5%) is referred to as the "catch-up". The catch-up provision is intended to provide the Investment Adviser with an incentive fee of 20.0% on all of our Pre-Incentive Fee Adjusted Net Investment Income as if a hurdle rate did not apply when our Pre-Incentive Fee Adjusted Net Investment Income exceeds 2.5% in any calendar quarter.

•	20.0% of the amount of our Pre-Incentive Fee Adjusted Net Investment Income, if any, that exceeds 2.5% in any calendar quarter (10.0% annualized) is payable to the Investment Adviser once the hurdle is reached and the catch-up is achieved.

*	The hypothetical amount of pre-incentive fee net investment income shown is based on a percentage of total net assets and assumes, for our investments held prior to the IPO, interest income has been adjusted to reflect the amortization of purchase or original issue discount as if each investment was purchased at the date of the IPO, or stepped up to fair market value.

The hypothetical amounts of returns shown are based on a percentage of our total net assets and assume no leverage. There is no guarantee that positive returns will be realized and actual returns may vary from those shown in this example. The capital gains incentive fees are calculated on an "adjusted" basis for our investments held prior to the IPO and assumes those investments have been adjusted to reflect the amortization of purchase or original issue discount as if each investment was purchased at the date of the IPO, or stepped up to fair market value.

(1)	As noted above, it is possible that the cumulative aggregate capital gains fee received by the Investment Adviser ($7.0 million) is effectively greater than $5.0 million (20.0% of cumulative aggregate realized capital gains less net realized capital losses or net unrealized depreciation ($25.0 million)).

The Annual Distribution Requirement for a RIC will be satisfied if we distribute (or are deemed to distribute) to our stockholders on an annual basis at least 90.0% of our net ordinary income plus the excess of realized net short-term capital gains over realized net long-term capital losses, if any. Because we use debt financing, we are subject to an asset coverage ratio requirement under the 1940 Act, and we are subject to certain financial

•

The source-of-income requirement will be satisfied if at least 90.0% of our allocable share of our gross income for each year is derived from dividends, interest payments with respect to loans of certain securities, 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 asset diversification requirement will be satisfied if we meet certain asset diversification requirements at the end of each quarter of our taxable year. To satisfy this requirement, at least 50.0% of the value of our assets must consist of cash, cash equivalents, U.S. government securities, securities of other RICs, and other such securities if such other securities of any one issuer do not represent more than 5.0% of the value of our assets or more than 10.0% of the outstanding voting securities of the issuer; and no more than 25.0% of the value of our assets can be invested in the securities, other than U.S. government securities or securities of other RICs, of one issuer, of two or more issuers that are controlled, as determined under applicable Code rules, by it and that are engaged in the same or similar or related trades or businesses or of certain “qualified publicly traded partnerships”. Failure to meet these requirements may result in us having to dispose of certain investments quickly in order to prevent the loss of our RIC status. Because most of our investments are intended to be in private companies, and therefore may be relatively illiquid, any such dispositions could be made at disadvantageous prices and could result in substantial losses.

(1)	In applying the if-converted method, conversion is not assumed for purposes of computing diluted earnings per share if the effect would be anti-dilutive. For the year ended December 31, 2015, there was anti-dilution. For the years ended December 31, 2018, December 31, 2017, December 31, 2016 and December 31, 2014, there was no anti-dilution.

On January 1, 2016, we adopted Accounting Standard Update No. 2015-03, Interest—Imputation of Interest Subtopic 835-30—Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). Upon adoption, we revised our presentation of deferred financing costs from an asset to a liability, which is a direct deduction to our debt on the Consolidated Statements of Assets and Liabilities. In addition, as of December 31, 2015 and December 31, 2014, we retrospectively revised our presentation of $14.0 million and $14.1 million, respectively, of deferred financing costs that were previously presented as an asset, which resulted in a decrease to total assets and total liabilities as of December 31, 2015 and December 31, 2014.

(4)	Total return is calculated assuming a purchase of common stock at the opening of the first day of the period and a sale on the closing of the last business day of the respective period ends. Dividends and distributions, if any, are assumed for purposes of this calculation, to be reinvested at prices obtained under our dividend reinvestment plan.

(5)	Total return is calculated assuming a purchase at net asset value on the opening of the first day of the period and a sale at net asset value on the last day of the period. Dividends and distributions, if any, are assumed for purposes of this calculation, to be reinvested at the net asset value on the last day of the respective quarter.

The weighted average YTM at Cost calculation assumes that all investments, including secured collateralized agreements, not on non-accrual are purchased at the adjusted cost on the respective period ends and held until their respective maturities with no prepayments or losses and exited at par at maturity. The YTM at Cost for Investments calculation assumes that all investments, including secured collateralized agreements, are purchased at cost on the quarter end date and held until their respective maturities with no prepayments or losses and exited at par at maturity. YTM at Cost and YTM at Cost for Investments calculations exclude the impact of existing leverage. YTM at Cost and YTM at Cost for Investments use the London Interbank Offered Rate ("LIBOR") curves at each quarter's end date. The actual yield to maturity may be higher or lower due to the future selection of the LIBOR contracts by the individual companies in our portfolio or other factors. Adjusted cost reflects the cost for post-IPO investments in accordance with accounting principles generally accepted in the United States of America ("GAAP") and a stepped up cost basis of pre-IPO investments (assuming a step-up to fair market value occurred on the IPO date).

(1)	Investments for which market quotations are readily available on an exchange are valued at such market quotations based on the closing price indicated from independent pricing services.

(2)	Investments for which indicative prices are obtained from various pricing services and/or brokers or dealers are valued through a multi-step valuation process, as described below, to determine whether the quote(s) obtained is representative of fair value in accordance with GAAP.

a.

Bond quotes are obtained through independent pricing services. Internal reviews are performed by the investment professionals of the Investment Adviser to ensure that the quote obtained is representative of fair value in accordance with GAAP and, if so, the quote is used. If the Investment Adviser is unable to sufficiently validate the quote(s) internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below); and

b.	For investments other than bonds, the Company looks at the number of quotes readily available and performs the following procedures:

---

i.	Investments for which two or more quotes are received from a pricing service are valued using the mean of the mean of the bid and ask of the quotes obtained.

ii.

Investments for which one quote is received from a pricing service are validated internally. The investment professionals of the Investment Adviser analyze the market quotes obtained using an array of valuation methods (further described below) to validate the fair value. If the Investment Adviser is unable to sufficiently validate the quote internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below).

(3)	Investments for which quotations are not readily available through exchanges, pricing services, brokers, or dealers are valued through a multi-step valuation process:

a.	Each portfolio company or investment is initially valued by the investment professionals of the Investment Adviser responsible for the credit monitoring;

b.	Preliminary valuation conclusions will then be documented and discussed with the Company's senior management;

c.

If an investment falls into (3) above for four consecutive quarters and if the investment's par value or its fair value exceeds the materiality threshold, then at least once each fiscal year, the valuation for each portfolio investment for which the Company does not have a readily available market quotation will be reviewed by an independent valuation firm engaged by the Company's board of directors; and

d.	When deemed appropriate by the Company's management, an independent valuation firm may be engaged to review and value investment(s) of a portfolio company, without any preliminary valuation being performed by the Investment Adviser. The investment professionals of the Investment Adviser will review and validate the value provided.
