(the "Company") had six foreign domiciled portfolio companies, four of which are based in Canada and two of which are based in Europe. In total, these foreign domiciled portfolio investments represent 17.3% of total net asset value based on fair value. The Company generally acquires its investments in private transactions exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”).
These investments are generally subject to certain limitations on resale and may be deemed to be “restricted securities” under the Securities Act.
[7] Where appropriate, certain current year industry classifications may have been revised to more precisely reflect the business of the Company's investments.
[8] Except as noted, all investments were valued at fair value as determined in good faith by the Company’s Board of Directors (the "Board") using Level 3 inputs.
[9] All debt investments are income producing unless otherwise noted. All equity and warrant investments are non-income producing unless otherwise noted.

[11] Interest rate is the fixed or variable rate of the debt investments and does not include any original issue discount, end-of-term (“EOT”) payment, or additional fees related to such investments, such as deferred interest, commitment fees, prepayment fees or exit fees. EOT payments are contractual payments due in cash at the maturity date of the loan, including upon prepayment, and are a fixed rate determined at the inception of the loan. At the end of the term of certain equipment financings, the borrower has the option to purchase the underlying assets at fair value, generally subject to a cap, or return the equipment and pay a restocking fee. The fair values of the financed assets have been estimated as a percentage of original cost for purpose of the EOT payment value. The EOT payment is amortized and recognized as non-cash income over the term of the loan or equipment financing prior to its payment and is included as a component of the cost basis of the Company’s current debt securities.
[12] Investment has zero cost basis as it was purchased at a fair value of zero as part of the Formation Transactions (as defined in "Note 1 - Organization and Basis of Presentation").
[13] The interest rate on variable interest rate investments represents a benchmark rate plus spread. The benchmark interest rate is subject to an interest rate floor.
