The majority of the investments bear interest at a rate that may be determined by reference to London Interbank Offered Rate ("LIBOR" or "L") or Prime ("P") and which reset daily, monthly, quarterly or semiannually. For each, the Company has provided the spread over LIBOR or Prime and the weighted average current interest rate in effect as of December 31, 2017. Certain investments are subject to a LIBOR or Prime interest rate floor. For fixed rate loans, a spread above a reference rate is not applicable. Listed below are the index rates as of December 29, 2017. The actual index rate for each loan listed may not be the applicable index rate outstanding as of December 31, 2017, as the loan may have priced or repriced based on an index rate prior to December 29, 2017, which was the last business day of the period on which LIBOR was determined.

^(a) Denotes that all or a portion of the loan was indexed to the 30-day LIBOR, which was 1.56% as of December 29, 2017.

^(b) Denotes that all or a portion of the loan was indexed to the 60-day LIBOR, which was 1.62% as of December 29, 2017.

^(c) Denotes that all or a portion of the loan was indexed to the 90-day LIBOR, which was 1.69% as of December 29, 2017.

^(d) Denotes that all or a portion of the loan was indexed to the 180-day LIBOR, which was 1.84% as of December 29, 2017.

^(e) Denotes that all or a portion of the loan was indexed to the Prime rate, which was 4.50% as of December 29, 2017.


⁽²⁾	For portfolio companies with multiple interest rate contracts, the interest rate shown is a weighted average current interest rate in effect as of December 31, 2017.


⁽³⁾	The total principal amount is presented for debt investments while the number of shares or units owned is presented for equity investments.


⁽⁴⁾	The fair value of the investment was valued using significant unobservable inputs. See Note 5. Fair Value Measurements.


⁽⁵⁾	The negative fair value is the result of the capitalized discount on the loan or the unfunded commitment being valued below par. The negative amortized cost is the result of the capitalized discount being greater than the principal amount outstanding on the loan.


⁽⁶⁾	The entire commitment was unfunded as of December 31, 2017. As such, no interest is being earned on this investment. The investment may be subject to an unused facility fee.


⁽⁷⁾	Loan was on non-accrual status as of December 31, 2017, meaning that the Company has ceased recognizing interest income on the loan.

⁽⁸⁾

The investment is treated as a non-qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (the “1940 Act”). Under the 1940 Act, the Company may not acquire any non-qualifying asset unless, at the time the acquisition is made, qualifying assets represent at least 70% of the Company's total assets. As of December 31, 2017, total non-qualifying assets at fair value represented 6.3% of the Company's assets calculated in accordance with the 1940 Act.


⁽⁹⁾	The headquarters of this portfolio company is located in Canada.


⁽¹⁰⁾	Equity investments are non-income producing securities unless otherwise noted.


⁽¹¹⁾	Ownership of certain equity investments may occur through a holding company or partnership.


⁽¹²⁾	The Company holds an equity investment that entitles it to receive preferential dividends.


⁽¹³⁾	As defined in the 1940 Act, the Company is deemed to be an "affiliated person" of the portfolio company as the Company owns five percent or more of the portfolio company's voting securities ("non-controlled affiliate"). Transactions related to investments in non-controlled affiliates for the three months ended December 31, 2017 were as follows:



Portfolio Company	Fair value as of September 30, 2017		Purchases (cost)^(f)		Redemptions (cost)			Transfer in (out)		Discount accretion		Net change in unrealized gain/(loss)		Fair value as of December 31, 2017		Net realized gain/(loss)		Interest and fee income		Dividend income

^(f)	Purchases at cost includes amounts related to payment-in-kind ("PIK") interest capitalized and added to the principal balance of the respective loans.

⁽¹⁴⁾

As defined in the 1940 Act, the Company is deemed to be both an "affiliated person" of and "control" this portfolio company as the Company owns more than 25% of the portfolio company's outstanding voting securities or has the power to exercise control over management or policies of such portfolio company (including through a management agreement) ("controlled affiliate"). Transactions related to investments in controlled affiliates for the three months ended December 31, 2017 were as follows:

^(g)	Together with RGA Reinsurance Company ("RGA"), the Company co-invests through Senior Loan Fund LLC ("SLF"). SLF is capitalized as transactions are completed and all portfolio and investment decisions in respect to SLF must be approved by the SLF investment committee consisting of two representatives of the Company and RGA (with unanimous approval required from (i) one representative of each of the Company and RGA or (ii) both representatives of each of the Company and RGA). Therefore, although the Company owns more than 25% of the voting securities of SLF, the Company does not believe that it has control over SLF for purposes of the 1940 Act or otherwise.


⁽¹⁵⁾	The Company receives quarterly profit distributions from its equity investment in SLF. See Note 4. Investments.


⁽¹⁶⁾	The rate shown is the annualized seven-day yield as of December 31, 2017.

The majority of the investments bear interest at a rate that may be determined by reference to LIBOR or Prime and which reset daily, quarterly or semiannually. For each, the Company has provided the spread over LIBOR or Prime and the weighted average current interest rate in effect at September 30, 2017. Certain investments are subject to a LIBOR or Prime interest rate floor. For fixed rate loans, a spread above a reference rate is not applicable. Listed below are the index rates as of September 29, 2017. The actual index rate for each loan listed may not be the applicable index rate outstanding as of September 30, 2017, as the loan may have priced or repriced based on an index rate prior to September 29, 2017, which was the last business day of the period on which LIBOR was determined.

^(a) Denotes that all or a portion of the loan was indexed to the 30-day LIBOR, which was 1.23% as of September 29, 2017.

⁽²⁾	For portfolio companies with multiple interest rate contracts, the interest rate shown is a weighted average current interest rate in effect as of September 30, 2017.


⁽³⁾	The total principal amount is presented for debt investments while the number of shares or units owned is presented for equity investments.


⁽⁴⁾	The negative fair value is the result of the capitalized discount on the loan or the unfunded commitment being valued below par. The negative amortized cost is the result of the capitalized discount being greater than the principal amount outstanding on the loan.


⁽⁵⁾	The entire commitment was unfunded as of September 30, 2017. As such, no interest is being earned on this investment.


⁽⁶⁾	Loan was on non-accrual status as of September 30, 2017, meaning that the Company has ceased recognizing interest income on the loan.

The investment is treated as a non-qualifying asset under Section 55(a) of the 1940 Act. Under the 1940 Act, the Company may not acquire any non-qualifying asset unless, at the time the acquisition is made, qualifying assets represent at least 70% of the Company's total assets. As of September 30, 2017, total non-qualifying assets at fair value represented 6.7% of the Company's assets calculated in accordance with the 1940 Act.


⁽⁸⁾	The headquarters of this portfolio company is located in Canada.


⁽⁹⁾	Equity investments are non-income producing securities unless otherwise noted.


⁽¹⁰⁾	Ownership of certain equity investments may occur through a holding company or partnership.

Note 1. Organization

Golub Capital BDC, Inc. (“GBDC” and, collectively with its subsidiaries, the “Company”) is an externally managed, closed-end, non-diversified management investment company. GBDC has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). In addition, for U.S. federal income tax purposes, GBDC has elected to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).

The Company’s investment strategy is to invest primarily in senior secured and one stop (a loan that combines characteristics of traditional first lien senior secured loans and second lien or subordinated loans) loans of U.S. middle-market companies. The Company may also selectively invest in second lien and subordinated (a loan that ranks senior only to a borrower’s equity securities and ranks junior to all of such borrower’s other indebtedness in priority of payment) loans of, and warrants and minority equity securities in, U.S. middle-market companies. The Company has entered into an investment advisory agreement (the “Investment Advisory Agreement”) with GC Advisors LLC (the “Investment Adviser”), under which the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, the Company. Under an administration agreement (the “Administration Agreement”) the Company is provided with certain services by an administrator (the “Administrator”), which is currently Golub Capital LLC.

Note 2. Significant Accounting Policies and Recent Accounting Updates

Basis of presentation: The Company is an investment company as defined in the accounting and reporting guidance under Accounting Standards Codification (“ASC”) Topic 946 — Financial Services — Investment Companies (“ASC Topic 946”).

The accompanying interim consolidated financial statements of the Company and related financial information have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6, 10 and 12 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, the consolidated financial statements reflect all adjustments and reclassifications consisting solely of normal accruals that are necessary for the fair presentation of financial results as of and for the periods presented. All intercompany balances and transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation. The unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the financial statements and notes thereto in the Company’s Form 10-K for the year ended September 30, 2017, as filed with the U.S. Securities and Exchange Commission (the Commission or the SEC).

Fair value of financial instruments: The Company applies fair value to all of its financial instruments in accordance with ASC Topic 820 — Fair Value Measurement (“ASC Topic 820”). ASC Topic 820 defines fair value, establishes a framework used to measure fair value and requires disclosures for fair value measurements. In accordance with ASC Topic 820, the Company has categorized its financial instruments carried at fair value, based on the priority of the valuation technique, into a three-level fair value hierarchy. Fair value is a market-based measure considered from the perspective of the market participant who holds the financial instrument rather than an entity-specific measure. Therefore, when market assumptions are not readily available, the Company’s own assumptions are set to reflect those that management believes market participants would use in pricing the financial instrument at the measurement date.

The availability of observable inputs can vary depending on the financial instrument and is affected by a wide variety of factors, including, for example, the type of product, whether the product is new, whether the product is traded on an active exchange or in the secondary market and the current market conditions. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for financial instruments classified as Level 3.

Any changes to the valuation methodology are reviewed by management and the Company’s board of directors (the “Board”) to confirm that the changes are appropriate. As markets change, new products develop and the pricing for products becomes more or less transparent, the Company will continue to refine its valuation methodologies. See Note 5.

Use of estimates: The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at

Golub Capital BDC, Inc. and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

(In thousands, except shares and per share data)

the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Consolidation: As provided under Regulation S-X and ASC Topic 946, the Company will generally not consolidate its investment in a company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to the Company. Accordingly, the Company consolidated the results of the Company’s wholly-owned subsidiaries Golub Capital BDC 2010-1 Holdings LLC (“Holdings”), Golub Capital BDC 2010-1 LLC (“2010 Issuer”), Golub Capital BDC CLO 2014 LLC (“2014 Issuer”), Golub Capital BDC Funding LLC (“Funding”), Golub Capital BDC Holdings, LLC (“BDC Holdings”), GC SBIC IV, L.P. (“SBIC IV”), GC SBIC V, L.P. (“SBIC V”) and GC SBIC VI, L.P. (“SBIC VI”). The Company does not consolidate its non-controlling interest in SLF. See further description of the Company’s investment in SLF in Note 4.

Assets related to transactions that do not meet ASC Topic 860 - Transfers and Servicing (“ASC Topic 860”) requirements for accounting sale treatment are reflected in the Company’s Consolidated Statements of Financial Condition as investments. Those assets are owned by special purpose entities, including 2010 Issuer, 2014 Issuer and Funding, that are consolidated in the Company’s consolidated financial statements. The creditors of the special purpose entities have received security interests in such assets and such assets are not intended to be available to the creditors of GBDC (or any affiliate of GBDC).

Cash and cash equivalents: Cash and cash equivalents are highly liquid investments with an original maturity of three months or less at the date of acquisition. The Company deposits its cash in financial institutions and, at times, such balances may be in excess of the Federal Deposit Insurance Corporation insurance limits.

Restricted cash and cash equivalents: Restricted cash and cash equivalents include amounts that are collected and are held by trustees who have been appointed as custodians of the assets securing certain of the Company’s financing transactions. Restricted cash and cash equivalents are held by the trustees for payment of interest expense and principal on the outstanding borrowings or reinvestment into new assets. In addition, restricted cash and cash equivalents include amounts held within the Company’s small business investment company (“SBIC”) subsidiaries. The amounts held within the SBICs are generally restricted to the originations of new loans by the SBICs and the payment of U.S. Small Business Administration (“SBA”) debentures and related interest expense.

Revenue recognition:

Investments and related investment income: Interest income is accrued based upon the outstanding principal amount and contractual interest terms of debt investments.

Loan origination fees, original issue discount and market discount or premium are capitalized, and the Company accretes or amortizes such amounts over the life of the loan as interest income. For the three months ended December 31, 2017 and 2016, interest income included $2,709 and $1,807, respectively, of accretion of discounts. For the three months ended December 31, 2017 and 2016, the Company received loan origination fees of $2,069 and $1,914, respectively.

For investments with contractual PIK interest, which represents contractual interest accrued and added to the principal balance that generally becomes due at maturity, the Company will not accrue PIK interest if the portfolio company valuation indicates that the PIK interest is not collectible. For the three months ended December 31, 2017 and 2016, the Company recorded PIK income of $285 and $567, respectively, and received PIK payments in cash of $2 and $0, respectively.

In addition, the Company may generate revenue in the form of amendment, structuring or due diligence fees, fees for providing managerial assistance, consulting fees and prepayment premiums on loans. The Company records these fees as fee income when received. All other income is recorded into income when earned. For the three months ended December 31, 2017 and 2016, fee income included $435 and $166, respectively, of prepayment premiums, which fees are non-recurring.

For the three months ended December 31, 2017 and 2016, the Company received interest and fee income in cash, which excludes capitalized loan origination fees, in the amounts of $30,631 and $30,843 respectively.

Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Each distribution received from limited liability company (“LLC”) and limited partnership (“LP”) investments is evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from

Golub Capital BDC, Inc. and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

(In thousands, except shares and per share data)

equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment. For the three months ended December 31, 2017 and 2016, the Company recorded dividend income of $2,562 and $898, respectively, and return of capital distributions, excluding the Company's investment in LLC equity interests in SLF, of $308 and $191, respectively, and return of capital distributions from the Company's investment in LLC equity interest in SLF of $4,200 and $0, respectively.

Investment transactions are accounted for on a trade-date basis. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of investment, without regard to unrealized gains or losses previously recognized. The Company reports current period changes in fair value of investments that are measured at fair value as a component of the net change in unrealized appreciation (depreciation) on investments in the Consolidated Statements of Operations.

Non-accrual loans: A loan may be left on accrual status during the period the Company is pursuing repayment of the loan. Management reviews all loans that become 90 days or more past due on principal and interest, or when there is reasonable doubt that principal or interest will be collected, for possible placement on non-accrual status. When a loan is placed on non-accrual status, unpaid interest credited to income is reversed. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment. Non-accrual loans are restored to accrual status when past due principal and interest is paid and, in management’s judgment, payments are likely to remain current. The total fair value of non-accrual loans was $1,825 and $2,955 as of December 31, 2017 and September 30, 2017, respectively.

Partial loan sales: The Company follows the guidance in ASC Topic 860 when accounting for loan participations and other partial loan sales. Such guidance requires a participation or other partial loan sale to meet the definition of a “participating interest”, as defined in the guidance, in order for sale treatment to be allowed. Participations or other partial loan sales which do not meet the definition of a participating interest remain on the Company’s Consolidated Statements of Financial Condition and the proceeds are recorded as a secured borrowing until the definition is met. Secured borrowings are carried at fair value to correspond with the related investments, which are carried at fair value. See Note 6 for additional information.

Income taxes: The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. In order to qualify and be subject to tax as a RIC, among other things, the Company is required to meet certain source of income and asset diversification requirements and timely distribute dividends for U.S. federal income tax purposes to its stockholders of an amount generally at least equal to 90% of investment company taxable income, as defined by the Code and determined without regard to any deduction for dividends paid, for each tax year. The Company has made, and intends to continue to make, the requisite distributions to its stockholders, which will generally relieve the Company from U.S. federal income taxes with respect to all income distributed to its stockholders.

Depending on the level of taxable income earned in a tax year, the Company may choose to retain taxable income in excess of current year dividend distributions, and would distribute such taxable income in the next tax year. The Company may then be required to incur a 4% excise tax on such income. To the extent that the Company determines that its estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as taxable income is earned. For the three months ended December 31, 2017 and 2016, $0 and $10, respectively, was incurred for U.S. federal excise tax.

The Company accounts for income taxes in conformity with ASC Topic 740 — Income Taxes (“ASC Topic 740”). ASC Topic 740 provides guidelines for how uncertain tax positions should be recognized, measured, presented and disclosed in financial statements. ASC Topic 740 requires the evaluation of tax positions taken in the course of preparing the Company’s tax returns to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax expense or tax benefit in the current year. It is the Company’s policy to recognize accrued interest and penalties related to uncertain tax benefits in income tax expense. There were no material unrecognized tax benefits or unrecognized tax liabilities related to uncertain income tax positions through December 31, 2017. The Company's tax returns for the 2014 through 2016 tax years remain subject to examination by U.S. federal and most state tax authorities.

Dividends and distributions: Dividends and distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend or distribution is determined by the Board each quarter and is generally based upon the earnings estimated

by management. Net realized capital gains, if any, are distributed at least annually, although the Company may decide to retain such capital gains for investment.

The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of any distributions the Company declares in cash on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, if the Board authorizes and the Company declares a cash distribution, then stockholders who participate in the DRIP will have their cash distribution reinvested in additional shares of the Company’s common stock, rather than receiving the cash distribution. The Company may use newly issued shares under the guidelines of the DRIP (if the Company’s shares are trading at a premium to net asset value), or the Company may purchase shares in the open market in connection with the obligations under the plan. In particular, if the Company’s shares are trading at a significant discount to net asset value (“NAV”) and the Company is otherwise permitted under applicable law to purchase such shares, the Company intends to purchase shares in the open market in connection with any obligations under the DRIP.

In the event the market price per share of the Company’s common stock on the date of a distribution exceeds the most recently computed NAV per share of the common stock, the Company will issue shares of common stock to participants in the DRIP at the greater of the most recently computed NAV per share of common stock or 95% of the current market price per share of common stock (or such lesser discount to the current market price per share that still exceeds the most recently computed NAV per share of common stock).

Share repurchase plan: The Company has a share repurchase program (the “Program”) which allows the Company to repurchase up to $75,000 of the Company’s outstanding common stock on the open market at prices below the Company’s NAV as reported in its most recently published consolidated financial statements. The Board most recently reapproved the Program in August 2017 and the Program may be implemented at the discretion of management. The shares may be purchased from time to time at prevailing market prices, through open market transactions, including block transactions. The Company did not make any repurchases of its common stock during the three months ended December 31, 2017 and 2016.

Deferred debt issuance costs: Deferred debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. As of December 31, 2017 and September 30, 2017, the Company had deferred debt issuance costs of $3,514 and $4,273, respectively. These amounts are amortized and included in interest expense in the Consolidated Statements of Operations over the estimated average life of the borrowings. Amortization expense for the three months ended December 31, 2017 and 2016 was $794 and $849, respectively.

Deferred offering costs: Deferred offering costs consist of fees paid in relation to legal, accounting, regulatory and printing work completed in preparation of equity offerings. Deferred offering costs are charged against the proceeds from equity offerings when received. As of December 31, 2017 and September 30, 2017, deferred offering costs, which are included in other assets on the Consolidated Statements of Financial Condition, were $111 and $111, respectively.

Accounting for derivative instruments: The Company does not utilize hedge accounting and marks its derivatives, if any, to market through a net change in unrealized appreciation (depreciation) on derivative instruments in the Consolidated Statements of Operations.

Recent accounting pronouncements: In November 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash Restricted Cash, a consensus of the FASB Emerging Issues Task Force, which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. This guidance is effective for annual reporting periods, and the interim periods within those periods, beginning after December 15, 2017. The Company adopted the ASU, which did not have a material impact on the Company’s consolidated financial statements. Prior to adoption, the Company presented the change in restricted cash and cash equivalents separately as a cash flow from investing activity. Upon adoption, the Company included the restricted cash and cash equivalents in each of the balances of the cash, cash equivalents and restricted cash and cash equivalents at the beginning of and end of periods and included the change in restricted cash and cash equivalents as part of the net change in cash, cash equivalents and restricted cash and cash equivalents in the Consolidated Statements of Cash Flows and retrospectively restated the three months ended December 31, 2016.

Investment Advisory Agreement: Under the Investment Advisory Agreement, the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, GBDC. The Board most recently reapproved the Investment Advisory Agreement in May 2017. The Investment Adviser is a registered investment adviser with the Securities and Exchange Commission

Golub Capital BDC, Inc. and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

(In thousands, except shares and per share data)

(the “SEC”). The Investment Adviser receives fees for providing services, consisting of two components, a base management fee and an Incentive Fee (as defined below).

The base management fee is calculated at an annual rate equal to 1.375% of average adjusted gross assets at the end of the two most recently completed calendar quarters (including assets purchased with borrowed funds and securitization-related assets, leverage, unrealized depreciation or appreciation on derivative instruments and cash collateral on deposit with custodian but adjusted to exclude cash and cash equivalents so that investors do not pay the base management fee on such assets) and is payable quarterly in arrears. Additionally, the Investment Adviser is voluntarily excluding assets funded with secured borrowing proceeds from the base management fee. The base management fee is adjusted, based on the actual number of days elapsed relative to the total number of days in such calendar quarter, for any share issuances or repurchases during such calendar quarter. For purposes of the Investment Advisory Agreement, cash equivalents means U.S. government securities and commercial paper instruments maturing within 270 days of purchase (which is different than the GAAP definition, which defines cash equivalents as U.S. government securities and commercial paper instruments maturing within 90 days of purchase). To the extent that the Investment Adviser or any of its affiliates provides investment advisory, collateral management or other similar services to a subsidiary of the Company, the base management fee will be reduced by an amount equal to the product of (1) the total fees paid to the Investment Adviser by such subsidiary for such services and (2) the percentage of such subsidiary’s total equity, including membership interests and any class of notes not exclusively held by one or more third parties, that is owned, directly or indirectly, by the Company.

The Company has structured the calculation of the Incentive Fee to include a fee limitation such that an Incentive Fee for any quarter can only be paid to the Investment Adviser if, after such payment, the cumulative Incentive Fees paid to the Investment Adviser since April 13, 2010, the effective date of the Company’s election to become a BDC, would be less than or equal to 20.0% of the Company’s Cumulative Pre-Incentive Fee Net Income (as defined below).

The Company accomplishes this limitation by subjecting each quarterly Incentive Fee payable under the Income and Capital Gain Incentive Fee Calculation (as defined below) to a cap (the “Incentive Fee Cap”). The Incentive Fee Cap in any quarter is equal to the difference between (a) 20.0% of Cumulative Pre-Incentive Fee Net Income and (b) cumulative Incentive Fees of any kind paid to the Investment Adviser by GBDC since April 13, 2010. To the extent the Incentive Fee Cap is zero or a negative value in any quarter, no Incentive Fee would be payable in that quarter. If, for any relevant period, the Incentive Fee Cap calculation results in the Company paying less than the amount of the Incentive Fee calculated above, then the difference between the Incentive Fee and the Incentive Fee Cap will not be paid by GBDC and will not be received by the Investment Adviser as an Incentive Fee either at the end of such relevant period or at the end of any future period. “Cumulative Pre-Incentive Fee Net Income” is equal to the sum of (a) Pre-Incentive Fee Net Investment Income (as defined below) for each period since April 13, 2010 and (b) cumulative aggregate realized capital gains, cumulative aggregate realized capital losses, cumulative aggregate unrealized capital depreciation and cumulative aggregate unrealized capital appreciation since April 13, 2010.

“Pre-Incentive Fee Net Investment Income” means interest income, dividend income and any other income (including any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that the Company receives from portfolio companies but excluding fees for providing managerial assistance) accrued during the calendar quarter, minus operating expenses for the calendar quarter (including the base management fee, taxes, any expenses payable under the Investment Advisory Agreement and the Administration Agreement, any expenses of securitizations and any interest expense and dividends paid on any outstanding preferred stock, but excluding the Incentive Fee). Pre-Incentive Fee Net Investment Income includes, in the case of investments with a deferred interest feature such as market discount, debt instruments with PIK interest, preferred stock with PIK dividends and zero coupon securities, accrued income that the Company has not yet received in cash.

Incentive Fees are calculated and payable quarterly in arrears (or, upon termination of the Investment Advisory Agreement, as of the termination date).

The income and capital gains incentive fee calculation (the “Income and Capital Gain Incentive Fee Calculation”) has two parts, the income component (the “Income Incentive Fee”) and the capital gains component (the “Capital Gain Incentive Fee” and, together with the Income Incentive Fee, the “Incentive Fee”). The Income Incentive Fee is calculated quarterly in arrears based on the Company’s Pre-Incentive Fee Net Investment Income for the immediately preceding calendar quarter.

For the three months ended December 31, 2017 and 2016, the Income Incentive Fee incurred was $2,158 and $1,611, respectively.

Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. Because of the structure of the Income Incentive Fee, it is possible that an Incentive Fee may be

Golub Capital BDC, Inc. and Subsidiaries

Notes to Unaudited Consolidated Financial Statements

(In thousands, except shares and per share data)

calculated under this formula with respect to a period in which the Company has incurred a loss. For example, if the Company receives Pre-Incentive Fee Net Investment Income in excess of the hurdle rate (as defined below) for a calendar quarter, the Income Incentive Fee will result in a positive value and an Incentive Fee will be paid even if the Company has incurred a loss in such period due to realized and/or unrealized capital losses unless the payment of such Incentive Fee would cause the Company to pay Incentive Fees on a cumulative basis that exceed the Incentive Fee Cap. Pre-Incentive Fee Net Investment Income, expressed as a rate of return on the value of the Company’s net assets (defined as total assets less indebtedness and before taking into account any Incentive Fees payable during the period) at the end of the immediately preceding calendar quarter, is compared to a fixed “hurdle rate” of 2.0% quarterly. If market interest rates rise, the Company may be able to invest funds in debt instruments that provide for a higher return, which would increase Pre-Incentive Fee Net Investment Income and make it easier for the Investment Adviser to surpass the fixed hurdle rate and receive an Incentive Fee based on such net investment income.

The Company’s Pre-Incentive Fee Net Investment Income used to calculate this part of the Incentive Fee is also included in the amount of its total assets (excluding cash and cash equivalents but including assets purchased with borrowed funds and securitization-related assets, unrealized depreciation or appreciation on derivative instruments and cash collateral on deposit with custodian) used to calculate the 1.375% base management fee annual rate.

The Company calculates the Income Incentive Fee with respect to its Pre-Incentive Fee Net Investment Income quarterly, in arrears, as follows:


•	Zero in any calendar quarter in which the Pre-Incentive Fee Net Investment Income does not exceed the hurdle rate;

•

100% of the Company’s Pre-Incentive Fee Net Investment Income with respect to that portion of such Pre-Incentive Fee Net Investment Income, if any, that exceeds the hurdle rate but is less than 2.5% in any calendar quarter. This portion of the Company’s Pre-Incentive Fee Net Investment Income (which exceeds the hurdle rate but is less than 2.5%) is referred to as the “catch-up” provision. The catch-up is meant to provide the Investment Adviser with 20.0% of the Pre-Incentive Fee Net Investment Income as if a hurdle rate did not apply if the Company’s Pre-Incentive Fee Net Investment Income exceeds 2.5% in any calendar quarter; and


•	20.0% of the amount of the Company’s Pre-Incentive Fee Net Investment Income, if any, that exceeds 2.5% in any calendar quarter.

The Capital Gain Incentive Fee equals (a) 20.0% of the Company’s Capital Gain Incentive Fee Base (as defined below), if any, calculated in arrears as of the end of each calendar year (or upon termination of the Investment Advisory Agreement, as of the termination date), which commenced with the calendar year ending December 31, 2010, less (b) the aggregate amount of any previously paid Capital Gain Incentive Fees. The Company’s “Capital Gain Incentive Fee Base” equals (1) the sum of (i) realized capital gains, if any, on a cumulative positive basis from the date the Company elected to become a BDC through the end of each calendar year, (ii) all realized capital losses on a cumulative basis and (iii) all unrealized capital depreciation on a cumulative basis less (2) all unamortized deferred debt issuance costs, if and to the extent such costs exceed all unrealized capital appreciation on a cumulative basis.


•	The cumulative aggregate realized capital losses are calculated as the sum of the amounts by which (a) the net sales price of each investment in the Company’s portfolio when sold is less than (b) the accreted or amortized cost basis of such investment.


•	The cumulative aggregate realized capital gains are calculated as the sum of the differences, if positive, between (a) the net sales price of each investment in the Company’s portfolio when sold and (b) the accreted or amortized cost basis of such investment.


•	The aggregate unrealized capital depreciation is calculated as the sum of the differences, if negative, between (a) the valuation of each investment in the Company’s portfolio as of the applicable Capital Gain Incentive Fee calculation date and (b) the accreted or amortized cost basis of such investment.

In accordance with GAAP, the Company also is required to include the aggregate unrealized capital appreciation on investments in the calculation and accrue a capital gain incentive fee on a quarterly basis as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement. If the Capital Gain Incentive Fee Base, adjusted as required by GAAP to include unrealized appreciation, is positive at the end of a period, then GAAP requires the Company to accrue a capital gain incentive fee equal to 20% of such amount, less the aggregate amount of the actual Capital Gain Incentive Fees paid and capital gain incentive fees accrued under GAAP in all prior periods. If such amount is negative, then there is no accrual for such period. The resulting accrual under GAAP in a

given period may result in additional expense if such cumulative amount is greater than in the prior period or a reversal of previously recorded expense if such cumulative amount is less than in the prior period. There can be no assurance that such unrealized capital appreciation will be realized in the future. For the three months ended December 31, 2017 and 2016, the Company accrued a capital gain incentive fee of $713 and $480, respectively, which accruals are included in incentive fee in the Consolidated Statements of Operations. As of December 31, 2017 and September 30, 2017, included in management and incentive fees payable on the Consolidated Statements of Financial Condition were $7,609 and $6,896, respectively, for cumulative accruals for capital gain incentive fees under GAAP, including the amounts payable pursuant to the Investment Advisory Agreement describes above.

As December 31, 2017 and September 30, 2017 the Capital Gain Incentive Fee payable as calculated under the Investment Advisory Agreement (as described above) was $1,196 and $0, respectively. However, in accordance with GAAP, the accrual for the Capital Gain Incentive Fee was $7,609 and $6,896 as of December 31, 2017 and September 30, 2017, respectively. The accrual for the Capital Gains Incentive Fee is included in management and incentive fees payable on the Consolidated Statements of Financial Condition.

The sum of the Income Incentive Fee and the Capital Gain Incentive Fee is the “Incentive Fee.”

Administration Agreement: Under the Administration Agreement, the Administrator furnishes the Company with office facilities and equipment, provides the Company with clerical, bookkeeping and record keeping services at such facilities and provides the Company with other administrative services as the Administrator, subject to review by the Board, determines necessary to conduct the Company’s day-to-day operations. GBDC reimburses the Administrator the allocable portion of overhead and other expenses incurred by it in performing its obligations under the Administration Agreement, including rent, fees and expenses associated with performing compliance functions and GBDC’s allocable portion of the cost of its chief financial officer and chief compliance officer and their respective staffs. The Board reviews such expenses to determine that these expenses are reasonable and comparable to administrative services charged by unaffiliated third party asset managers. Under the Administration Agreement, the Administrator also provides, on the Company’s behalf, managerial assistance to those portfolio companies to which the Company is required to provide such assistance and will be paid an additional amount based on the cost of the services provided, which amount shall not exceed the amount the Company receives from such portfolio companies.

Included in accounts payable and accrued expenses is $618 and $620 as of December 31, 2017 and September 30, 2017, respectively, for accrued allocated shared services under the Administration Agreement.

Other related party transactions: The Administrator pays for certain unaffiliated third-party expenses incurred by the Company. Such expenses include postage, printing, office supplies, rating agency fees and professional fees. These expenses are not marked-up and represent the same amount the Company would have paid had the Company paid the expenses directly. These expenses are subsequently reimbursed in cash.

Total expenses reimbursed to the Administrator during the three months ended December 31, 2017 and 2016 were $799 and $582, respectively.

As of December 31, 2017 and September 30, 2017, included in accounts payable and accrued expenses were $521 and $799, respectively, for accrued expenses paid on behalf of the Company by the Administrator.

On June 22, 2016, the Company entered into an unsecured revolving credit facility with the Investment Adviser (the "Adviser Revolver"), with a maximum credit limit of $20,000 and expiration date of June 22, 2019. Refer to Note 6 for discussion of the Adviser Revolver.

During the three months ended December 31, 2017 and 2016, the Company sold $0 and $38,307, respectively, of investments and unfunded commitments to SLF at fair value and recognized $0 and $266, respectively, of net realized gains.

During the three months ended December 31, 2017 and 2016, SLF incurred an administrative service fee of $113 and $127, respectively, to reimburse the Administrator for expenses pursuant to an administrative and loan services agreement by and between SLF and the Administrator.

Senior Loan Fund LLC:

The Company co-invests with RGA in senior secured loans through SLF, an unconsolidated Delaware LLC. SLF is capitalized as transactions are completed and all portfolio and investment decisions in respect of SLF must be approved by the SLF investment committee consisting of two representatives of each of the Company and RGA (with unanimous approval required from (i) one representative of each of the Company and RGA or (ii) both representatives of each of the Company and RGA). SLF may cease making new investments upon notification of either member but operations will continue until all investments have been sold or paid-off in the normal course of business. Investments held by SLF are measured at fair value using the same valuation methodologies as described in Note 5.

As of December 31, 2017, SLF was capitalized by LLC equity interest subscriptions from its members.

Note 5. Fair Value Measurements

The Company follows ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the assets or liabilities or market and the assets’ or liabilities’ complexity. The Company’s fair value analysis includes an analysis of the value of any unfunded loan commitments. Assets and liabilities are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the transparency of the inputs to the valuation of the asset or liability as of the measurement date. The three levels are defined as follows:

Level 1: Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2: Inputs include quoted prices for similar assets or liabilities in active markets and inputs that are observable for the assets or liabilities, either directly or indirectly, for substantially the full term of the assets or liabilities.

Level 3: Inputs include significant unobservable inputs for the assets or liabilities and include situations where there is little, if any, market activity for the assets or liabilities. The inputs into the determination of fair value are based upon the best information available and may require significant management judgment or estimation.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset’s or a liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company assesses the levels of assets and liabilities at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the three months ended December 31, 2017 and 2016. The following section describes the valuation techniques used by the Company to measure different assets and liabilities at fair value and includes the level within the fair value hierarchy in which the assets and liabilities are categorized.

Investments

Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by the Board, based on input of management, the audit committee and independent valuation firms that have been engaged at the direction of the Board to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing twelve-month period under a valuation policy and a consistently applied valuation process. This valuation process is conducted at the end of each fiscal quarter, with approximately 25% (based on the number of portfolio companies) of the Company’s valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. All investments as of December 31, 2017 and September 30, 2017, with the exception of money market funds included in cash, cash equivalents and restricted cash and cash equivalents (Level 1 investments) and investments measured at fair value using the NAV, were valued using Level 3 inputs.

When determining fair value of Level 3 debt and equity investments, the Company may take into account the following factors, where relevant: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities, and changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”). A portfolio company’s EBITDA may include pro forma adjustments for items such as acquisitions, divestitures, or expense reductions. The enterprise value analysis is performed to determine the value of equity investments and to determine if debt investments are credit impaired. If debt investments are credit impaired, the Company will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, the Company uses a market interest rate yield analysis to determine fair value.

Notes to Unaudited Consolidated Financial Statements

(In thousands, except shares and per share data)

In addition, for certain debt investments, the Company may base its valuation on indicative bid and ask prices provided by an independent third party pricing service. Bid prices reflect the highest price that the Company and others may be willing to pay. Ask prices represent the lowest price that the Company and others may be willing to accept. The Company generally uses the midpoint of the bid/ask range as its best estimate of fair value of such investment.

Due to the inherent uncertainty of determining the fair value of Level 3 investments that do not have a readily available market value, the fair value of the investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that may ultimately be received or settled. Further, such investments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded instruments. If the Company were required to liquidate a portfolio investment in a forced or liquidation sale, the Company may realize significantly less than the value at which such investment had previously been recorded. The Company’s investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

Secured Borrowings

The Company has elected the fair value option under ASC Topic 825 - Financial Instruments, relating to accounting for debt obligations at their fair value for its secured borrowings which arose due to partial loan sales which did not meet the criteria for sale treatment under ASC Topic 860. The Company reports changes in the fair value of its secured borrowings as a component of the net change in unrealized (appreciation) depreciation on secured borrowings in the Consolidated Statements of Operations. The net gain or loss reflects the difference between the fair value and the principal amount due on maturity.

As of December 31, 2017 and September 30, 2017, there were no secured borrowings outstanding. As of December 31, 2016 all secured borrowings were valued using Level 3 inputs under the fair value hierarchy, and the Company’s approach to determining fair value of Level 3 secured borrowings is consistent with its approach to determining fair value of the Level 3 investments that are associated with these secured borrowings as previously described.

The following tables present fair value measurements of the Company’s investments and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value as of December 31, 2017 and September 30, 2017:

The above tables are not intended to be all-inclusive but rather to provide information on significant unobservable inputs and valuation techniques used by the Company.

The significant unobservable inputs used in the fair value measurement of the Company’s debt and equity investments are EBITDA multiples, revenue multiples and market interest rates. The Company uses EBITDA multiples and, to a lesser extent, revenue multiples on its debt and equity investments and secured borrowings to determine any credit gains or losses. Increases or decreases in either of these inputs in isolation would result in a significantly lower or higher fair value measurement. The Company uses market interest rates for loans to determine if the effective yield on a loan is commensurate with the market yields for that type of loan. If a loan’s effective yield is significantly less than the market yield for a similar loan with a similar credit profile, then the resulting fair value of the loan may be lower.

Other Financial Assets and Liabilities

ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. As a result, with the exception of the line item titled “debt” which is reported at cost, all assets and liabilities approximate fair value on the Consolidated Statements of Financial Condition due to their short maturity. Fair value of the Company’s debt is estimated using Level 3 inputs by discounting remaining payments using comparable market rates or market quotes for similar instruments at the measurement date, if available.

Note 6. Borrowings

In accordance with the 1940 Act, with certain limited exceptions, the Company is only allowed to borrow amounts such that its asset coverage, as defined in the 1940 Act, is at least 200% after such borrowing. On September 13, 2011, the Company received exemptive relief from the SEC allowing it to modify the asset coverage requirement to exclude the SBA debentures from this calculation. As such, the Company’s ratio of total consolidated assets to outstanding indebtedness may be less than 200%. This provides the Company with increased investment flexibility but also increases its risks related to leverage. As of December 31, 2017, the Company’s asset coverage for borrowed amounts was 269.8% (excluding the SBA debentures).

Debt Securitizations: On July 16, 2010, the Company completed a $300,000 term debt securitization, which was subsequently increased to $350,000 (as amended, “2010 Debt Securitization”). The notes (“2010 Notes”) offered in the 2010 Debt Securitization were issued by the 2010 Issuer, a subsidiary of Holdings. Through October 19, 2016, the 2010 Debt Securitization consisted of $203,000 of Aaa/AAA Class A 2010 Notes that bore interest at a rate of three-month LIBOR plus 1.74%, $12,000 of Class B 2010 Notes that bore interest at a rate of three-month LIBOR plus 2.40% and $135,000 of Subordinated 2010 Notes that do not bear interest. On October 20, 2016, the Company and the 2010 Issuer further amended the 2010 Debt Securitization to, among other things, (a) refinance the issued Class A 2010 Notes by redeeming in full the Class A 2010 Notes and issuing new Class A-Refi 2010 Notes in an aggregate principal amount of $205,000 that bear interest at a rate of three-month LIBOR plus 1.90%, (b) refinance the Class B Notes by redeeming in full the Class B 2010 Notes and issuing new Class B-Refi 2010 Notes in an aggregate principal amount of $10,000 that bear interest at a rate of three-month LIBOR plus 2.40%, and (c) extend the reinvestment period applicable to the 2010 Issuer to July 20, 2018. Following the refinancing, Holdings retained the Class B-Refi 2010 Notes. The Class A-Refi 2010 Notes and Class B-Refi 2010 Notes are secured by the assets held by the 2010 Issuer.

The Class A-Refi 2010 Notes are included in the December 31, 2017 and September 30, 2017, Consolidated Statement of Financial Condition as debt of the Company and the Class B-Refi 2010 Notes were eliminated in consolidation. As of December 31, 2017 and September 30, 2017, the Subordinated 2010 Notes were eliminated in consolidation.

The Investment Adviser serves as collateral manager to the 2010 Issuer and the 2014 Issuer under separate collateral management agreements and receives a fee for providing these services. The total fees payable by the Company under its Investment Advisory Agreement are reduced by an amount equal to the total aggregate fees that are paid to the Investment Adviser by the 2010 Issuer and the 2014 Issuer for rendering such collateral management services are paid to the Investment Adviser by the 2010 Issuer and the 2014 Issuer for rendering such collateral management services.

As part of each of the 2010 Debt Securitization and the 2014 Debt Securitization, GBDC entered into master loan sale agreements under which GBDC agreed to directly or indirectly sell or contribute certain senior secured and second lien loans (or participation interests therein) to the 2010 Issuer and the 2014 Issuer, as applicable, and to purchase or otherwise acquire the Subordinated 2010 Notes and the LLC equity interests in the 2014 Issuer, as applicable. The 2010 Notes (other than the Subordinated 2010 Notes) and the 2014 Notes are the secured obligations of the 2010 Issuer and 2014 Issuer, respectively, and indentures governing each of the 2010 Notes and the 2014 Notes include customary covenants and events of default.

SBA Debentures: On August 24, 2010, SBIC IV received approval for a license from the SBA to operate as an SBIC. On December 5, 2012, SBIC V received a license from the SBA to operate as an SBIC. On January 10, 2017, SBIC VI received a license from the SBA to operate as an SBIC. SBICs are subject to a variety of regulations and oversight by the SBA concerning the size and nature of the companies in which they may invest as well as the structures of those investments.

The licenses allow the SBICs to obtain leverage by issuing SBA-guaranteed debentures, subject to issuance of a capital commitment by the SBA and customary procedures. These debentures are non-recourse to GBDC, have interest payable semiannually and a ten-year maturity. The interest rate is fixed at the time of issuance at a market-driven spread over U.S. Treasury Notes with ten-year maturities.

Under present SBIC regulations, the maximum amount of SBA-guaranteed debentures that may be issued by multiple licensees under common management is $350,000 and the maximum amount that a single SBIC licensee may issue is $150,000. As of December 31, 2017, SBIC IV, SBIC V and SBIC VI had $125,000, $133,000 and $9,000, respectively, of outstanding SBA-guaranteed debentures that mature between September 2021 and September 2027, leaving incremental borrowing capacity of $17,000 and $41,000 for SBIC

Revolving Credit Facility: On July 21, 2011, Funding entered into a senior secured revolving credit facility (as amended, the “Credit Facility”) with Wells Fargo Bank, N.A., as administrative agent and lender, which as of December 31, 2017, allowed Funding to borrow up to $170,000 at any one time outstanding, subject to leverage and borrowing base restrictions.

Through a series of amendments during the three months ended December 31, 2017, most recently on December 14, 2017, the Company and Funding amended the Credit Facility to, among other things, decrease the size of the Credit Facility from $225,000 to $170,000 and decrease the interest the Credit Facility bears from one-month LIBOR plus 2.25% to one-month LIBOR plus 2.15%. The reinvestment period expires on September 27, 2018 and the stated maturity date is September 28, 2022. In addition to the stated interest rate on the Credit Facility, the Company is required to pay a non-usage fee at a rate between 0.50% and 2.00% per annum depending on the size of the unused portion of the Credit Facility.

The Credit Facility is collateralized by all of the assets held by Funding, and GBDC has pledged its interests in Funding as collateral to Wells Fargo Bank, N.A., as the collateral agent, under an ancillary agreement to secure the obligations of GBDC as the transferor and servicer under the Credit Facility. Both GBDC and Funding have made customary representations and warranties and are required to comply with various covenants, reporting requirements and other customary requirements for similar credit facilities. Borrowing under the Credit Facility is subject to the leverage restrictions contained in the 1940 Act.

The Company has transferred certain loans and debt securities it has originated or acquired from time to time to Funding through a purchase and sale agreement and may cause Funding to originate or acquire loans in the future, consistent with the Company’s investment objectives.

As of December 31, 2017 and September 30, 2017, the Company had outstanding debt under the Credit Facility of $110,300 and $63,100, respectively. For the three months ended December 31, 2017 and 2016, the Company had borrowings on the Credit Facility of $98,600 and $130,250 and repayments on the Credit Facility of $51,400 and $101,450, respectively.

Secured Borrowings: Certain partial loan sales do not qualify for sale accounting under ASC Topic 860 because these sales do not meet the definition of a “participating interest”, as defined in the guidance, in order for sale treatment to be allowed. Participations or other partial loan sales which do not meet the definition of a participating interest remain as an investment on the Consolidated Statement of Financial Condition and the portion sold is recorded as a secured borrowing in the liabilities section of the Consolidated Statement of Financial Condition. For these partial loan sales, the interest earned on the entire loan balance is recorded within “interest income” and the interest earned by the buyer in the partial loan sale is recorded within “interest and other debt financing expenses” in the Consolidated Statement of Operations.

As of December 31, 2017 and September 30, 2017, there were no secured borrowings outstanding.

Past secured borrowings were the result of the Company’s completion of partial loan sales of one stop loans associated with a portfolio company that did not meet the definition of a “participating interest.” As a result, sale treatment was not allowed and the partial loan sales were treated as secured borrowings.

Notes to Unaudited Consolidated Financial Statements

(In thousands, except shares and per share data)

During the three months ended December 31, 2016, there were no partial loan sales, no fundings on revolving and delayed draw secured borrowings and repayments on secured borrowings totaled $13.

Note 7. Commitments and Contingencies

Commitments: The Company had outstanding commitments to fund investments totaling $62,752 and $60,497 under various undrawn revolvers and other credit facilities as of December 31, 2017 and September 30, 2017, respectively. As described in Note 4, the Company had commitments of up to $81,742 and $77,543 to SLF as of December 31, 2017 and September 30, 2017, respectively, that may be contributed primarily for the purpose of funding new investments approved by the SLF investment committee.

Indemnifications: In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties that provide general indemnifications. The Company’s maximum exposure under these arrangements is unknown, as these involve future claims that may be made against the Company but that have not occurred. The Company expects the risk of any future obligations under these indemnifications to be remote.

Off-balance sheet risk: Off-balance sheet risk refers to an unrecorded potential liability that may result in a future obligation or loss, even though it does not appear on the Consolidated Statements of Financial Condition. The Company has entered and, in the future, may again enter into derivative instruments that contain elements of off-balance sheet market and credit risk. There were no commitments outstanding for derivative contracts as of December 31, 2017 and September 30, 2017. Derivative instruments can be affected by market conditions, such as interest rate volatility, which could impact the fair value of the derivative instruments. If market conditions move against the Company, it may not achieve the anticipated benefits of the derivative instruments and may realize a loss. The Company minimizes market risk through monitoring its investments and borrowings.

Concentration of credit and counterparty risk: Credit risk arises primarily from the potential inability of counterparties to perform in accordance with the terms of the contract. The Company has engaged and, in the future, may engage again in derivative transactions with counterparties. In the event that the counterparties do not fulfill their obligations, the Company may be exposed to risk. The risk of default depends on the creditworthiness of the counterparties or issuers of the instruments. The Company’s maximum loss that it could incur related to counterparty risk on its derivative instruments is the value of the collateral for that respective derivative instrument. It is the Company’s policy to review, as necessary, the credit standing of each counterparty.

Legal proceedings: In the normal course of business, the Company may be subject to legal and regulatory proceedings that are generally incidental to its ongoing operations. While there can be no assurance of the ultimate disposition of any such proceedings, the Company does not believe any disposition will have a material adverse effect on the Company’s consolidated financial statements.

In addition, for U.S. federal income tax purposes, we have elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code. As a business development company and a RIC, we are also subject to certain constraints, including limitations imposed by the 1940 Act and the Code.

Our shares are currently listed on The Nasdaq Global Select Market under the symbol “GBDC”.

Our investment objective is to generate current income and capital appreciation by investing primarily in senior secured and one stop loans of U.S. middle-market companies. We may also selectively invest in second lien and subordinated loans of, and warrants and minority equity securities in U.S. middle-market companies. We intend to achieve our investment objective by (1) accessing the established loan origination channels developed by Golub Capital, a leading lender to U.S. middle-market companies with over $20.0 billion in capital under management as of December 31, 2017, (2) selecting investments within our core middle-market company focus, (3) partnering with experienced private equity firms, or sponsors, in many cases with whom Golub Capital has invested alongside in the past, (4) implementing the disciplined underwriting standards of Golub Capital and (5) drawing upon the aggregate experience and resources of Golub Capital.

Our investment activities are managed by GC Advisors and supervised by our board of directors of which a majority of the members are independent of us, GC Advisors and its affiliates.

Under an investment advisory agreement, or the Investment Advisory Agreement, which was most recently reapproved by our board of directors in May 2017, we have agreed to pay GC Advisors an annual base management fee based on our average adjusted gross assets as well as an incentive fee based on our investment performance. Under an administration agreement, or the Administration Agreement, we are provided with certain administrative services by an administrator, or the Administrator, which is currently Golub Capital LLC.

Under the Administration Agreement, we have agreed to reimburse the Administrator for our allocable portion (subject to the review and approval of our independent directors) of overhead and other expenses incurred by the Administrator in performing its obligations under the Administration Agreement.

We seek to create a portfolio that includes primarily senior secured and one stop loans by primarily investing approximately $5.0 million to $30.0 million of capital, on average, in the securities of U.S. middle-market companies. We may also selectively invest more than $30.0 million in some of our portfolio companies and generally expect that the size of our individual investments will vary proportionately with the size of our capital base.

We generally invest in securities that have been rated below investment grade by independent rating agencies or that would be rated below investment grade if they were rated. These securities, which may be referred to as “junk,” have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. In addition, many of our debt investments have floating interest rates that reset on a periodic basis and typically do not fully pay down principal prior to maturity, which may increase our risk of losing part or all of our investment.

As of December 31, 2017 and September 30, 2017, our portfolio at fair value was comprised of the following:



	As of December 31, 2017				As of September 30, 2017

⁽¹⁾	Proceeds from the LLC equity interests invested in SLF were utilized by SLF to invest in senior secured loans.

One stop loans include loans to technology companies undergoing strong growth due to new services, increased adoption and/or entry into new markets. We refer to loans to these companies as late stage lending loans. Other targeted characteristics of late stage lending businesses include strong customer revenue retention rates, a diversified customer base and backing from growth equity or venture capital firms. In some cases, the borrower’s high revenue growth is supported by a high level of discretionary spending. As part of the underwriting of such loans and consistent with industry practice, we may adjust our characterization of the earnings of such borrowers for a reduction or elimination of such discretionary expenses, if appropriate. As of

December 31, 2017 and September 30, 2017, one stop loans included $151.8 million and $138.6 million, respectively, of late stage lending loans at fair value.

As of December 31, 2017 and September 30, 2017, we had debt and equity investments in 190 and 185 portfolio companies, respectively, and an investment in Senior Loan Fund LLC, or SLF.

The weighted average annualized income yield and weighted average annualized investment income yield of our earning portfolio company investments, which represented nearly 100% of our debt investments, for the three months ended ended December 31, 2017 and 2016 was as follows:



	For the three months ended December 31,
	2017	2016
Weighted average annualized income yield ⁽¹⁾⁽²⁾	7.9%	7.7%
Weighted average annualized investment income yield ⁽¹⁾⁽³⁾	8.5%	8.1%


⁽¹⁾	For the three months ended December 31, 2017, weighted average annualized income yield and weighted average annualized investment income yield do not reflect interest income from subordinated notes in SLF, which were redeemed on December 30, 2016.


⁽²⁾	Represents income from interest, including subordinated notes in SLF, and fees excluding amortization of capitalized fees and discounts divided by the average fair value of earning portfolio company investments, and does not represent a return to any investor in us.


⁽³⁾	Represents income from interest, including subordinated notes in SLF, fees and amortization of capitalized fees and discounts divided by the average fair value of earning portfolio investments, and does not represent a return to any investor in us.

The total return, based on the change in the quoted market price of our stock and assuming distributions were reinvested in accordance with the dividend reinvestment plan, or DRIP, for the three months ended December 31, 2017 and 2016, was (1.1)% and 2.2%, respectively. The total return does not include sales load.

Revenues: We generate revenue in the form of interest and fee income on debt investments and capital gains and distributions, if any, on portfolio company investments that we originate or acquire. Our debt investments, whether in the form of senior secured, one stop, second lien or subordinated loans, typically have a term of three to seven years and bear interest at a fixed or floating rate. In some instances, we receive payments on our debt investments based on scheduled amortization of the outstanding balances. In addition, we receive repayments of some of our debt investments prior to their scheduled maturity date. The frequency or volume of these repayments fluctuates significantly from period to period. Our portfolio activity also reflects the proceeds of sales of securities. In some cases, our investments provide for deferred interest payments or payment-in-kind, or PIK, interest. The principal amount of loans and any accrued but unpaid interest generally become due at the maturity date. In addition, we may generate revenue in the form of commitment, origination, amendment, structuring or due diligence fees, fees for providing managerial assistance and consulting fees. Loan origination fees, original issue discount and market discount or premium are capitalized, and we accrete or amortize such amounts as interest income. We record prepayment premiums on loans as fee income. For additional details on revenues, see “Critical Accounting Policies-Revenue Recognition.”

We recognize realized gains or losses on investments based on the difference between the net proceeds from the disposition and the amortized cost basis of the investment or derivative instrument, without regard to unrealized gains or losses previously recognized. We record current period changes in fair value of investments and derivative instruments that are measured at fair value as a component of the net change in unrealized appreciation (depreciation) on investments in the Consolidated Statements of Operations.

Significant U.S. federal tax reform legislation was recently enacted that, among other things, permanently reduces the maximum federal corporate income tax rate, reduces the maximum individual income tax rate (effective for taxable years 2018 through 2025), restricts the deductibility of business interest expense, changes the rules regarding the calculation of net operating loss deductions that may be used to offset taxable income, expands the circumstances in which a foreign corporation will be treated as a “controlled foreign corporation” and, under certain circumstances, requires accrual method taxpayers to recognize income for U.S. federal income tax purposes no later than the income is taken into account as revenue in an applicable financial statement. Although we do not expect any material, negative impact on us and our portfolio companies as a result of this legislation, we are continuing to evaluate.

Expenses: Our primary operating expenses include the payment of fees to GC Advisors under the Investment Advisory Agreement and interest expense on our outstanding debt. We bear all other out-of-pocket costs and expenses of our operations and transactions, including:


•	calculating our net asset value, or NAV (including the cost and expenses of any independent valuation firm);

•

fees and expenses incurred by GC Advisors payable to third parties, including agents, consultants or other advisors, in monitoring financial and legal affairs for us and in monitoring our investments and performing due diligence on our prospective portfolio companies or otherwise relating to, or associated with, evaluating and making investments, which fees and expenses may include, among other items, due diligence reports, appraisal reports, any studies that may be commissioned by GC Advisors and travel and lodging expenses;


•	expenses related to unsuccessful portfolio acquisition efforts;


•	offerings of our common stock and other securities;


•	administration fees and expenses, if any, payable under the Administration Agreement (including payments based upon our allocable portion of the Administrator’s overhead in performing its obligations under the Administration Agreement, including rent and the allocable portion of the cost of our chief compliance officer, chief financial officer and their respective staffs);


•	fees payable to third parties, including agents, consultants or other advisors, relating to, or associated with, evaluating and making investments in portfolio companies, including costs associated with meeting financial sponsors;


•	transfer agent, dividend agent and custodial fees and expenses;


•	U.S. federal and state registration and franchise fees;


•	all costs of registration and listing our shares on any securities exchange;


•	U.S. federal, state and local taxes;


•	independent directors’ fees and expenses;


•	costs of preparing and filing reports or other documents required by the SEC or other regulators;


•	costs of any reports, proxy statements or other notices to stockholders, including printing costs;


•	costs associated with individual or group stockholders;


•	costs associated with compliance under the Sarbanes-Oxley Act;


•	our allocable portion of any fidelity bond, directors and officers/errors and omissions liability insurance, and any other insurance premiums;


•	direct costs and expenses of administration, including printing, mailing, long distance telephone, copying, secretarial and other staff, independent auditors and outside legal costs;


•	proxy voting expenses; and


•	all other expenses incurred by us or the Administrator in connection with administering our business.

We expect our general and administrative expenses to be relatively stable or decline as a percentage of total assets during periods of asset growth and to increase during periods of asset declines.

GC Advisors, as collateral manager for Golub Capital BDC 2010-1 LLC, or the 2010 Issuer, our indirect subsidiary, under a collateral management agreement, or the 2010 Collateral Management Agreement, is entitled to receive an annual fee in an amount equal to 0.35% of the principal balance of the portfolio loans held by the 2010 Issuer at the beginning of the collection period relating to each payment date, which is payable in arrears on each payment date. Under the 2010 Collateral Management Agreement, the term ‘‘collection period’’ refers to a quarterly period running from the day after the end of the prior collection period to the fifth business day of the calendar month in which a payment date occurs.

GC Advisors, as collateral manager for Golub Capital BDC CLO 2014 LLC, or the 2014 Issuer, our wholly-owned subsidiary, under a collateral management agreement, or the 2014 Collateral Management Agreement, is entitled to receive an annual fee in an amount equal to 0.25% of the principal balance of the portfolio loans held by the 2014 Issuer at the beginning of the collection period relating to each payment date, which is payable in arrears on each payment date. Under the 2014 Collateral Management Agreement, the term ‘‘collection period’’ refers to a quarterly period running from the day after the end of the prior collection period to the tenth business day prior to the payment date.

Collateral management fees are paid directly by the 2010 Issuer and the 2014 Issuer to GC Advisors and offset against the management fees payable under the Investment Advisory Agreement. In addition, the 2010 Issuer and 2014 Issuer paid Wells Fargo Securities, LLC structuring and placement fees for its services in connection with the initial structuring and subsequent amendments of a $350.0 million term debt securitization, or the 2010 Debt Securitization and the initial structuring of a $402.6

million term debt securitization, or the 2014 Debt Securitization and, together with the 2010 Debt Securitization, the Debt Securitizations. The 2010 Issuer and 2014 Issuer also agreed to pay ongoing administrative expenses to the trustee, collateral manager, independent accountants, legal counsel, rating agencies and independent managers in connection with developing and maintaining reports, and providing required services in connection with the administration of the 2010 Debt Securitization and the 2014 Debt Securitization, as applicable.

We believe that these administrative expenses approximate the amount of ongoing fees and expenses that we would be required to pay in connection with a traditional secured credit facility. Our common stockholders indirectly bear all of these expenses.

Recent Developments

On February 6, 2018, our board of directors declared a quarterly distribution of $0.32 per share payable on March 30, 2018 to holders of record as of March 8, 2018.

⁽¹⁾	The investments in SLF include our investments in LLC equity interests in SLF for the three months ended December 31, 2017. For the three months ended December 31, 2016, the investments in SLF include our investments in both subordinated notes (prior to their redemption by SLF on December 30, 2016) and LLC equity interests in SLF.


⁽²⁾	Does not include our investment in LLC equity interests in SLF.

Net income can vary substantially from period to period for various reasons, including the recognition of realized gains and losses and unrealized appreciation and depreciation. As a result, quarterly comparisons of net income may not be meaningful.

Investment Income

Investment income increased from the three months ended December 31, 2016 to the three months ended December 31, 2017 by $2.6 million primarily as a result of an increase in the average earning debt investments balance, which is the average

balance of accruing loans in our investment portfolio, excluding our investment in the subordinated notes of SLF, of $42.2 million and increased prepayment fee income and accretion of discounts resulting from increased debt investment payoffs. These increases were partially offset by a decline in income from our investments in SLF, which was attributable to a decline in the credit performance of SLF's portfolio.

The annualized income yield by debt security type for the three months ended December 31, 2017 and 2016 was as follows:



	For the three months ended December 31,
	2017	2016
Senior secured	6.6%	6.3%
One stop	8.0%	7.8%
Second lien	9.5%	10.7%
Subordinated debt	19.8%	6.7%
Subordinated notes in SLF⁽¹⁾	N/A	8.5%


⁽¹⁾	SLF’s proceeds from the subordinated notes were utilized by SLF to invest in senior secured loans. SLF redeemed the outstanding balance on the subordinated notes on December 30, 2016.

Annualized income yields on one stop and senior secured loans increased for the three months ended December 31, 2017 due to the rise in London Interbank Offered Rate, or LIBOR. As of December 31, 2017, we have one second lien investment and one subordinated debt investment as shown in the consolidated schedule of investments. Due to the limited number of second lien and subordinated debt investments, quarterly income yields on second lien and subordinated debt investments can be significantly impacted by the addition, subtraction or refinancing of one investment. The decrease in the annualized income yield on second lien investments for the three months ended December 31, 2017 was driven by the payoff on higher yielding second lien investments. The increase in the annualized income yield on subordinated debt investments for the three months ended December 31, 2017 was driven by the payoff of a lower yielding subordinated debt investment.

For additional details on investment yields and asset mix, refer to the “Liquidity and Capital Resources - Portfolio Composition, Investment Activity and Yield” section below.

Expenses

The following table summarizes our expenses for the three months ended December 31, 2017 and 2016:



	For the three months ended December 31,				Variances
	2017		2016		2017 vs. 2016
	(In thousands)
Interest and other debt financing expenses	$	6,920	$	6,757	$	163

Average debt outstanding⁽¹⁾	$	791,710	$	881,880	$	(90,170	)

⁽¹⁾

For the three months ended December 31, 2017 there were no secured borrowings outstanding. For the three months ended December 31, 2016, we have excluded $0.5 million, respectively, of secured borrowings, at fair value, which were the result of participations and partial loan sales that did not meet the definition of a “participating interest”, as defined in the guidance to Accounting Standards Codification, or ASC, Topic 860 — Transfers and Servicing, or ASC Topic 860.

Interest Expense

Interest and other debt financing expenses increased by $0.2 million from the three months ended December 31, 2016 to the three months ended December 31, 2017 primarily due to the increase in LIBOR which was partially offset by a decrease in the weighted average of outstanding borrowings from $881.9 million for the three months ended December 31, 2016 to $791.7 million for the three months ended December 31, 2017. The decrease in our debt was primarily driven by a decrease in the outstanding balance on our Credit Facility of $16.4 million. Additionally, the decrease in our debt was driven by a decrease in our use of debt under our United States Small Business Administration, or SBA, debentures through our small business investment companies, or SBICs, which had outstanding balances of $267.0 million as of December 31, 2017 and $277.0 million as of December 31, 2016. The effective annualized average interest rate on our outstanding debt increased to 3.9% for the three months ended December 31, 2017 from 3.4% for the three months ended December 30, 2016 primarily due to the increase in LIBOR.

Management Fee

The base management fee remained stable from the three months ended December 31, 2016 to the three months ended December 31, 2017.

Incentive Fees

The incentive fee payable under the Investment Advisory Agreement consists of two parts: (1) the income component, or the Income Incentive Fee, and (2) the capital gains component, or the Capital Gain Incentive Fee. The Income Incentive Fee increased by $0.5 million from the three months ended December 31, 2016 to the three months ended December 31, 2017 primarily as a result of the increase in net investment income. This resulted in an increase in the rate of return on the value of our net assets for the three months ended December 31, 2017. For the three months ended December 31, 2017, while still not fully through the catch-up provision of the Income Incentive Fee calculation, the Income Incentive Fee as a percentage of Pre-Incentive Fee Net Investment Income (as defined below) increased to 10.1% compared to 8.5% for the three months ended December 31, 2016.

The Capital Gain Incentive Fee equals (a) 20.0% of our Capital Gain Incentive Fee Base (as defined below), if any, calculated in arrears as of the end of each calendar year less (b) the aggregate amount of any previously paid Capital Gain Incentive Fees. Our “Capital Gain Incentive Fee Base” equals (1) the sum of (i) realized capital gains, if any, on a cumulative positive basis from the date the we elected to become a BDC through the end of each calendar year, (ii) all realized capital losses on a cumulative basis and (iii) all unrealized capital depreciation on a cumulative basis less (2) all unamortized deferred financing costs, if and to the extent such costs exceed all unrealized capital appreciation on a cumulative basis. In addition, in accordance with generally accepted accounting principles in the United States of America, or GAAP, we are required to also include the aggregate unrealized capital appreciation on investments in the calculation and accrue the capital gain incentive fee as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement.

The accrual for capital gain incentive fee was $0.7 million, or $0.01 per share, and $0.5 million, or $0.01 per share, for the three months ended December 31, 2017 and 2016, respectively. The increase in the accrual for capital gain incentive fee for the three months ended December 31, 2017 from the three months ended December 31, 2016 was primarily the result of increased unrealized appreciation on portfolio company investments. For additional details on unrealized appreciation and depreciation of investments, refer to the “Net Realized and Unrealized Gains and Losses” section below.

The cumulative capital gain incentive fee accrued in accordance with GAAP as of December 31, 2017 and 2016 was $7.6 million and $4.6 million, respectively, of which $1.2 million and $0, respectively, were payable as a Capital Gain Incentive Fee pursuant to the Investment Advisory Agreement.

Professional Fees, Administrative Service Fee, and General and Administrative Expenses

In total, professional fees, the administrative service fee, and general and administrative expenses increased from the three months ended December 31, 2016 to the three months ended December 31, 2017 by $0.1 million. In general, we expect certain of our operating expenses, including professional fees, the administrative service fee, and other general and administrative expenses to decline as a percentage of our total assets during periods of growth and increase as a percentage of our total assets during periods of asset declines.

The Administrator pays for certain expenses incurred by us. These expenses are subsequently reimbursed in cash. Total expenses reimbursed by us to the Administrator for the three months ended December 31, 2017 and 2016 were $0.8 million and $0.6 million, respectively.

As of December 31, 2017 and September 30, 2017, included in accounts payable and accrued expenses were $0.5 million and $0.8 million, respectively, for accrued expenses paid on behalf of us by the Administrator.

Excise Tax Expense

We have elected to be treated as a RIC under Subchapter M of the Code and operate in a manner so as to qualify for the tax treatment applicable to RICs. In order to be subject to tax as a RIC, we are required to meet certain source of income and asset diversification requirements, as well as timely distribute to our stockholders dividends for U.S. federal income tax purposes of an amount generally at least equal to 90% of investment company taxable income, as defined by the Code, and determined without regard to any deduction for dividends paid for each tax year. We have made and intend to continue to make the requisite distributions to our stockholders that will generally relieve us from U.S. federal income taxes.

Depending on the level of taxable income earned in a tax year, we may choose to retain taxable income in excess of current year distributions into the next tax year in an amount less than what would trigger payments of U.S. federal income tax under Subchapter M of the Code. We may then be required to incur a 4% excise tax on such income. To the extent that we determine that our estimated current year annual taxable income may exceed estimated current year distributions, we accrue excise tax, if any, on estimated excess taxable income as taxable income is earned. For the three months ended December 31, 2017 and 2016, we incurred a net expense of $0 and $10,000, respectively, for U.S. federal excise tax.

Net Realized and Unrealized Gains and Losses

The following table summarizes our net realized and unrealized gains (losses) for the periods presented:



	For the three months ended December 31,						Variances

⁽¹⁾	Unrealized appreciation on investments in SLF includes our investment in LLC equity interests in SLF.


⁽²⁾	Unrealized (depreciation) on investments in SLF includes our investment in LLC interests in SLF.

For the three months ended December 31, 2017, we had a net realized gain of $0.5 million primarily due to the sale of six equity investments above their fair value, which was partially offset by the write off of one non-accrual portfolio company investment.

For the three months ended December 31, 2017, we had $10.5 million in unrealized appreciation on 105 portfolio company investments, which was partially offset by $8.9 million in unrealized depreciation on 147 portfolio company investments. Unrealized appreciation during the three months ended December 31, 2017 resulted from an increase in fair value primarily due to the rise in market prices of portfolio company investments. Unrealized depreciation primarily resulted from the amortization of discounts, negative credit related adjustments that caused a reduction in fair value and the reversal of the net unrealized appreciation associated with the sales of portfolio company investments during the three months ended December 31, 2017.

For the three months ended December 31, 2017, we had $0.8 million in unrealized appreciation on our investment in SLF LLC equity interests, which was primarily driven by increased net investment income at SLF.

For the three months ended December 31, 2016, we had a net realized gain of $0.9 million primarily due to the net realized gains on the sale of portfolio company investments to SLF and the sale of two equity investments.

For the three months ended December 31, 2016, we had $9.2 million in unrealized appreciation on 110 portfolio company investments, which was partially offset by $7.6 million in unrealized depreciation on 144 portfolio company investments. Unrealized appreciation during the three months ended December 31, 2016 resulted from an increase in fair value primarily due to the rise in market prices of portfolio company investments. Unrealized depreciation primarily resulted from the amortization of discounts, negative credit related adjustments that caused a reduction in fair value and the reversal of the net unrealized appreciation associated with the sales of portfolio company investments during the three months ended December 31, 2016.

For the three months ended December 31, 2016, we had $0.5 million in unrealized depreciation on our investment in SLF LLC equity interests, which was primarily driven by SLF's one non-accrual portfolio company investment.

Liquidity and Capital Resources

For the three months ended December 31, 2017, we experienced a net increase in cash, cash equivalents and restricted cash and cash equivalents of $14.6 million. During the period, cash used in operating activities was $11.6 million, primarily as a result of fundings of portfolio investments of $137.9 million, partially offset by the proceeds from principal payments and sales of portfolio investments of $101.9 million and net investment income of $18.5 million. Lastly, cash provided by financing activities was $26.2 million, primarily driven by borrowings on debt of $98.6 million that were partially offset by repayments of debt of $51.4 million and distributions paid of $21.0 million.

For the three months ended December 31, 2016, we experienced a net decrease in cash, cash equivalents and restricted cash and cash equivalents of $17.8 million. During the period, cash used in operating activities was $13.9 million, primarily as a result of fundings of portfolio investments of $122.7 million, partially offset by the proceeds from principal payments and sales of portfolio investments of $93.9 million. Lastly, cash used in financing activities was $3.9 million, primarily driven by repayments of debt of $111.5 million and distributions paid of $28.2 million that were partially offset by borrowings on debt of $136.3 million.

As of December 31, 2017 and September 30, 2017, we had cash and cash equivalents of $5.8 million and $4.0 million, respectively. In addition, we had restricted cash and cash equivalents of $71.4 million and $58.6 million as of December 31, 2017 and September 30, 2017, respectively. Cash and cash equivalents are available to fund new investments, pay operating expenses and pay distributions. As of December 31, 2017, $46.7 million of our restricted cash and cash equivalents could be used to fund new investments that meet the investment guidelines established in the Debt Securitizations, which are described in further detail in Note 6 to our consolidated financial statements, and for the payment of interest expense on the notes issued in the Debt Securitizations. As of December 31, 2017, $13.7 million of our restricted cash and cash equivalents could be used to fund investments that meet the guidelines under the Credit Facility as well as for the payment of interest expense and revolving debt of the Credit Facility. As of December 31, 2017, $11.0 million of our restricted cash and cash equivalents could be used to fund new investments that meet the regulatory and investment guidelines established by the SBA for our SBICs, which are described in further detail in Note 6 to our consolidated financial statements, and for interest expense and fees on our outstanding SBA debentures.

As of December 31, 2017, the Credit Facility allowed Funding to borrow up to $170.0 million at any one time outstanding, subject to leverage and borrowing base restrictions. As of December 31, 2017 and September 30, 2017, we had $110.3 million and $63.1 million outstanding under the Credit Facility, respectively. As of December 31, 2017 and September 30, 2017, subject to leverage and borrowing base restrictions, we had approximately $59.7 million and $161.9 million, respectively, of remaining commitments and $59.7 million and $95.0 million, respectively, of availability on the Credit Facility.

On June 22, 2016, we entered into an unsecured revolving credit facility with GC Advisors, or the Adviser Revolver, which permits us to borrow up to $20.0 million at any one time outstanding. We entered into the Adviser Revolver in order to have the ability to borrow funds on a short-term basis and have in the past repaid, and generally intend in the future to repay, borrowings under the Adviser Revolver within the same quarter in which they are drawn. As of December 31, 2017 and September 30, 2017, we had no amounts outstanding on the Adviser Revolver.

On July 16, 2010, we completed the 2010 Debt Securitization, which was subsequently increased to $350.0 million. On October 20, 2016, we further amended the 2010 Debt Securitization to, among other things, (a) refinance the issued Class A notes issued by the 2010 Issuer, or the 2010 Notes, by redeeming in full the $203.0 million Class A 2010 Notes and issuing new Class A-Refi 2010 Notes in an aggregate principal amount of $205.0 million that bear interest at a rate of three-month LIBOR plus 1.90%, (b) refinance the Class B 2010 Notes by redeeming in full the $12.0 million Class B 2010 Notes and issuing new

Class B-Refi 2010 Notes in an aggregate principal amount of $10.0 million that bear interest at a rate of three-month LIBOR plus 2.40%, and (c) extend the reinvestment period applicable to the 2010 Issuer to July 20, 2018. Following the refinancing, Golub Capital BDC 2010-1 Holdings LLC, our wholly-owned subsidiary, or Holdings, retained the Class B-Refi 2010 Notes.

As of December 31, 2017 and September 30, 2017, the 2010 Notes consisted of $205.0 million of Class A-Refi 2010 Notes, which bear interest at a rate of three-month LIBOR plus 1.90%, $10.0 million of Class B-Refi 2010 Notes, which bear interest at a rate of three-month LIBOR plus 2.40%, and $135.0 million face amount of Subordinated 2010 Notes that do not bear interest. The Class A-Refi 2010 Notes are included in the December 31, 2017 and September 30, 2017 Consolidated Statements of Financial Condition as our debt and the Class B-Refi 2010 Notes and Subordinated 2010 Notes were eliminated in consolidation. As of December 31, 2017 and September 30, 2017, we had outstanding debt under the 2010 Debt Securitization of $205.0 million.

On June 5, 2014, we completed the 2014 Debt Securitization in which the 2014 Issuer issued an aggregate of $402.6 million of notes, or the 2014 Notes, including $191.0 million of Class A-1 2014 Notes, which bear interest at a rate of three-month LIBOR plus 1.75%, $20.0 million of Class A-2 2014 Notes, which bear interest at a rate of three-month LIBOR plus 1.95%, $35.0 million of Class B 2014 Notes, which bear interest at a rate of three-month LIBOR plus 2.50%, $37.5 million of Class C 2014 Notes, which bear interest at a rate of three-month LIBOR plus 3.50%, and $119.1 million of LLC equity interests in the 2014 Issuer that do not bear interest. We retained all of the Class C 2014 Notes and LLC equity interests in the 2014 Issuer totaling $37.5 million and $119.1 million, respectively. The Class A-1, Class A-2 and Class B 2014 Notes are included in the December 31, 2017 and September 30, 2017 Consolidated Statements of Financial Condition as our debt and the Class C 2014 Notes and LLC equity interests in the 2014 Issuer were eliminated in consolidation. As of December 31, 2017 and September 30, 2017, we had outstanding debt under the 2014 Debt Securitization of $246.0 million.

Under present SBIC regulations, the maximum amount of SBA-guaranteed debentures that may be issued by multiple licensees under common management is $350.0 million and the maximum amount that a single SBIC licensee may issue is $150.0 million. As of December 31, 2017, GC SBIC IV, L.P., or SBIC IV, GC SBIC V, L.P., or SBIC V, and GC SBIC VI, L.P., or SBIC VI, had $125.0 million, $133.0 million, and $9.0 million, respectively, of outstanding SBA-guaranteed debentures that mature between September 2021 and September 2027 leaving incremental borrowing capacity of $17.0 million and $41.0 million for SBIC V and SBIC VI, respectively, under present SBIC regulations. As of September 30, 2017, SBIC IV, SBIC V and SBIC VI had $125.0 million, $133.0 million and $9.0 million, respectively, of outstanding SBA-guaranteed debentures that mature between September 2021 and September 2027.

In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to borrow amounts such that our asset coverage, as defined in the 1940 Act, is at least 200% after such borrowing. On September 13, 2011, we received exemptive relief from the SEC allowing us to modify the asset coverage requirement to exclude the SBA debentures from this calculation. As such, our ratio of total consolidated assets to outstanding indebtedness may be less than 200%. This provides us with increased investment flexibility but also increases our risks related to leverage. As of December 31, 2017, our asset coverage for borrowed amounts was 269.8% (excluding the SBA debentures).

As of December 31, 2017 and September 30, 2017, we had outstanding commitments to fund investments, excluding our investments in SLF, totaling $62.8 million and $60.5 million, respectively. These amounts may or may not be funded to the borrowing party now or in the future. The unfunded commitments relate to loans with various maturity dates, but the entire amount was eligible for funding to the borrowers, subject to the terms of each loan’s respective credit agreement. As of December 31, 2017, we believe that we had sufficient assets and liquidity to adequately cover future obligations under our unfunded commitments based on historical rates of drawings upon unfunded commitments, cash and restricted cash balances that we maintain, availability under our Credit Facility and Adviser Revolver and ongoing principal repayments on debt investments. In addition, we generally hold some syndicated loans in larger portfolio companies that are saleable over a relatively short period to generate cash.

Although we expect to fund the growth of our investment portfolio through the net proceeds from future securities offerings and through our DRIP as well as future borrowings, to the extent permitted by the 1940 Act, we cannot assure you that our efforts to raise capital will be successful. In addition, we may, from time to time, amend or refinance our leverage facilities and borrowings, including refinancing the 2010 Notes and the 2014 Notes, in order to, among other things, modify covenants or the interest rates payable and extend the reinvestment period or maturity date. In addition to capital not being available, it also may not be available on favorable terms. To the extent we are not able to raise capital on what we believe are favorable terms, we will focus on optimizing returns by investing capital generated from repayments into new investments we believe are attractive from a risk/reward perspective. Furthermore, to the extent we are not able to raise capital and are at or near our targeted leverage ratios, we may receive smaller allocations, if any, on new investment opportunities under GC Advisors’ allocation policy and have, in the past, received such smaller allocations under similar circumstances.

Portfolio Composition, Investment Activity and Yield

⁽¹⁾	19 and 19 of our loans included a feature permitting a portion of the interest due on such loan to be PIK interest as of December 31, 2017 and September 30, 2017, respectively.


⁽²⁾	We refer to a loan as non-accrual when we cease recognizing interest income on the loan because we have stopped pursuing repayment of the loan or, in certain circumstances, it is past due 90 days or more on principal and interest or our management has reasonable doubt that principal or interest will be collected. See “— Critical Accounting Policies — Revenue Recognition.”


⁽³⁾	The negative fair value is the result of the unfunded commitment being valued below par.


⁽⁴⁾	Proceeds from the LLC equity interests invested in SLF were utilized by SLF to invest in senior secured loans.

As of December 31, 2017 and September 30, 2017, the fair value of our debt investments as a percentage of the outstanding principal value was 99.1% and 98.9%, respectively.

As of December 31, 2017, 99.6% and 99.6% of our debt portfolio at fair value and at amortized cost, respectively, had interest rate floors that limit the minimum applicable interest rates on such loans. As of September 30, 2017, 99.6% and 99.6% of our debt portfolio at fair value and at amortized cost, respectively, had interest rate floors that limit the minimum applicable interest rates on such loans.

As of December 31, 2017 and September 30, 2017, the portfolio median earnings before interest, taxes, depreciation and amortization, or EBITDA, for our portfolio companies (excluding SLF) was $26.3 million and $25.2 million, respectively. The portfolio median EBITDA is based on the most recently reported trailing twelve-month EBITDA received from the portfolio company.

As part of the monitoring process, GC Advisors regularly assesses the risk profile of each of our investments and rates each of them based on an internal system developed by Golub Capital and its affiliates. This system is not generally accepted in our industry or used by our competitors. It is based on the following categories, which we refer to as GC Advisors’ internal performance ratings:




Internal Performance Ratings
Rating		Definition
5		Involves the least amount of risk in our portfolio. The borrower is performing above expectations, and the trends and risk factors are generally favorable.
4		Involves an acceptable level of risk that is similar to the risk at the time of origination. The borrower is generally performing as expected, and the risk factors are neutral to favorable.
3		Involves a borrower performing below expectations and indicates that the loan’s risk has increased somewhat since origination. The borrower may be out of compliance with debt covenants; however, loan payments are generally not past due.
2		Involves a borrower performing materially below expectations and indicates that the loan’s risk has increased materially since origination. In addition to the borrower being generally out of compliance with debt covenants, loan payments may be past due (but generally not more than 180 days past due).
1		Involves a borrower performing substantially below expectations and indicates that the loan’s risk has substantially increased since origination. Most or all of the debt covenants are out of compliance and payments are substantially delinquent. Loans rated 1 are not anticipated to be repaid in full and we will reduce the fair market value of the loan to the amount we anticipate will be recovered.

Our internal performance ratings do not constitute any rating of investments by a nationally recognized statistical rating organization or represent or reflect any third-party assessment of any of our investments.

For any investment rated 1, 2 or 3, GC Advisors will increase its monitoring intensity and prepare regular updates for the investment committee, summarizing current operating results and material impending events and suggesting recommended actions.

GC Advisors monitors and, when appropriate, changes the internal performance ratings assigned to each investment in our portfolio. In connection with our valuation process, GC Advisors and our board of directors review these internal performance ratings on a quarterly basis.

The following table shows the distribution of our investments on the 1 to 5 internal performance rating scale at fair value as of December 31, 2017 and September 30, 2017:



	December 31, 2017				September 30, 2017

Senior Loan Fund LLC

We co-invest with RGA Reinsurance Company, or RGA, in senior secured loans through SLF, an unconsolidated Delaware LLC. SLF is capitalized as transactions are completed and all portfolio and investment decisions in respect to SLF must be approved by the SLF investment committee consisting of two representatives of each of us and RGA (with unanimous approval required from (i) one representative of each of us and RGA or (ii) both representatives of each of us and RGA). SLF may cease making new investments upon notification of either member but operations will continue until all investments have been sold or paid-off in the normal course of business.

As of December 31, 2017, SLF is capitalized by LLC equity interest subscriptions from its members. On December 14, 2016, the SLF investment committee approved the recapitalization of the commitments of SLF’s members. On December 30, 2016, SLF’s members entered into additional LLC equity interest subscriptions totaling $160.0 million, SLF issued capital calls totaling $89.9 million to us and RGA and the subordinated notes previously issued by SLF were redeemed and terminated. As of December 31, 2017 and September 30, 2017, we and RGA owned 87.5% and 12.5%, respectively, of the LLC equity interests. SLF’s profits and losses are allocated to us and RGA in accordance with our respective ownership interests.

As of December 31, 2017, the senior secured revolving credit facility, or, as amended, the SLF Credit Facility, that Senior Loan Fund II LLC, a wholly-owned subsidiary of SLF, or SLF II, entered into with Wells Fargo Securities, LLC, as administrative agent, and Wells Fargo Bank, N.A., as lender, allows SLF II to borrow up to $200.0 million subject to leverage and borrowing base restrictions. The reinvestment period of the SLF Credit Facility ends August 29, 2018, and the stated maturity date is August 30, 2020. As of December 31, 2017 and September 30, 2017, SLF II had outstanding debt under the SLF Credit Facility of $180.2 million and $197.7 million, respectively. Through the reinvestment period, the SLF Credit Facility bears interest at one-month LIBOR plus a rate between 1.75% and 2.15%, depending on the composition of the collateral asset portfolio, per annum.

As of December 31, 2017 and September 30, 2017, SLF had total assets at fair value of $285.1 million and $306.2 million, respectively.

As of September 30, 2017, SLF had one portfolio company investment on non-accrual status with a fair value of $0.3 million. The portfolio companies in SLF are in industries and geographies similar to those in which we may invest directly. Additionally, as of

December 31, 2017 and September 30, 2017, SLF had commitments to fund various undrawn revolving credit and delayed draw loans to its portfolio companies totaling $12.2 million and $13.3 million, respectively.

⁽²⁾	The total principal amount is presented for debt investments while the number of shares or units owned is presented for equity investments.


⁽³⁾	Represents the fair value in accordance with ASC Topic 820. The determination of such fair value is not included in our board of directors’ valuation process described elsewhere herein.


⁽⁴⁾	We also hold a portion of the senior secured loan in this portfolio company.


⁽⁵⁾	The negative fair value is the result of the unfunded commitment being valued below par.


⁽⁶⁾	The entire commitment was unfunded as of September 30, 2017. As such, no interest is being earned on this investment.


⁽⁷⁾	Loan was on non-accrual status as of September 30, 2017, meaning that SLF has ceased recognizing interest income on the loan.


⁽⁸⁾	Equity investment received as a result of the portfolio company's debt restructuring.


⁽⁹⁾	Non-income producing.

As of December 31, 2017, we have committed to fund $175.0 million of LLC equity interests to SLF. As of December 31, 2017 and September 30, 2017, $93.3 million and $97.5 million, respectively, of our LLC equity interest commitment to SLF had been called and contributed, net of return of capital distributions subject to recall. For the three months ended December 31, 2017 and 2016, we received $2.0 million and $0.7 million, respectively, in dividend income from the SLF LLC equity interests.

The subordinated notes previously held by us were redeemed on December 30, 2016, and therefore no interest income was earned for the three months ended December 31, 2017. For the three months ended December 31, 2016, we earned interest income of $1.6 million, on the subordinated notes.

For the three months ended December 31, 2017 and 2016, we earned an annualized total return on our weighted average capital invested in SLF of 11.4% and 7.1%, respectively. The annualized total return on weighted average capital invested is calculated by dividing total income earned on our investments in SLF by the combined daily average of our investments in (1) the principal of the SLF subordinated notes, if any, and (2) the NAV of the SLF LLC equity interests.

Below is certain summarized financial information for SLF as of December 31, 2017 and September 30, 2017, and for the three months ended December 31, 2017 and 2016:

Prior to their termination, SLF elected to fair value the subordinated notes issued to us and RGA under ASC Topic 825 — Financial Instruments, or ASC Topic 825. The subordinated notes were valued by calculating the net present value of the future expected cash flow streams using an appropriate risk-adjusted discount rate model. For the three months ended December 31, 2016, SLF did not recognize unrealized appreciation or depreciation on the subordinated notes.

Unfunded commitments represent unfunded commitments to fund investments, excluding our investments in SLF, as of December 31, 2017. These amounts may or may not be funded to the borrowing party now or in the future. The unfunded commitments relate to loans with various maturity dates, but we are showing this amount in the less than one year category as this entire amount was eligible for funding to the borrowers as of December 31, 2017, subject to the terms of each loan’s respective credit agreement.

We may become a party to financial instruments with off-balance sheet risk in the normal course of our business to meet the financial needs of our portfolio companies. These instruments may include commitments to extend credit and involve, to varying degrees, elements of liquidity and credit risk in excess of the amount recognized in the balance sheet. As of December 31, 2017 and September 30, 2017, we had outstanding commitments to fund investments, excluding our investments in SLF, totaling $62.8 million and $60.5 million, respectively. We have commitments of up to $81.7 million and $77.5 million to SLF as of December 31, 2017 and September 30, 2017, respectively, that may be contributed primarily for the purpose of funding new investments approved by the SLF investment committee.

We have certain contracts under which we have material future commitments. We have entered into the Investment Advisory Agreement with GC Advisors in accordance with the 1940 Act. Under the Investment Advisory Agreement, GC Advisors provides us with investment advisory and management services.

Under the Administration Agreement, the Administrator furnishes us with office facilities and equipment, provides us with clerical, bookkeeping and record keeping services at such facilities and provides us with other administrative services necessary to conduct our day-to-day operations. The Administrator also provides on our behalf managerial assistance to those portfolio companies to which we are required to offer to provide such assistance.

If any of the contractual obligations discussed above are terminated, our costs under any new agreements that we enter into may increase. In addition, we would likely incur significant time and expense in locating alternative parties to provide the services we receive under our Investment Advisory Agreement and our Administration Agreement. Any new investment advisory agreement would also be subject to approval by our stockholders.

Distributions

We intend to make quarterly distributions to our stockholders as determined by our board of directors. For additional details on distributions, see “Income taxes” in Note 2 to our consolidated financial statements.

We may not be able to achieve operating results that will allow us to make distributions at a specific level or to increase the amount of our distributions from time to time. In addition, we may be limited in our ability to make distributions due to the asset coverage requirements applicable to us as a business development company under the 1940 Act. If we do not distribute a certain percentage of our income annually, we will suffer adverse U.S. federal income tax consequences, including the possible loss of our ability to be subject to tax as a RIC. We cannot assure stockholders that they will receive any distributions.

Because federal income tax regulations differ from GAAP, distributions in accordance with tax regulations may differ from net investment income and realized gains recognized for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified within capital accounts in the financial statements to reflect their tax character. For example, permanent differences in classification may result from the treatment of distributions paid from short-term gains as ordinary income dividends for tax purposes. Temporary differences arise when certain items of income, expense, gain or loss are recognized at some time in the future.

To the extent our taxable earnings fall below the total amount of our distributions for any tax year, a portion of those distributions may be deemed a return of capital to our stockholders for U.S. federal income tax purposes. Thus, the source of a distribution to our stockholders may be the original capital invested by the stockholder rather than our income or gains. Stockholders should read any written disclosure accompanying a distribution payment carefully and should not assume that the source of any distribution is our ordinary income or gains.

We have adopted an “opt out” dividend reinvestment plan for our common stockholders. As a result, if we declare a distribution, our stockholders’ cash distributions will be automatically reinvested in additional shares of our common stock unless a stockholder specifically “opts out” of our dividend reinvestment plan. If a stockholder opts out, that stockholder will receive cash distributions. Although distributions paid in the form of additional shares of our common stock will generally be subject to U.S. federal, state and local taxes in the same manner as cash distributions, stockholders participating in our dividend reinvestment plan will not receive any corresponding cash distributions with which to pay any such applicable taxes.

Related Party Transactions

We have entered into a number of business relationships with affiliated or related parties, including the following:


•	We entered into the Investment Advisory Agreement with GC Advisors. Mr. Lawrence Golub, our chairman, is a manager of GC Advisors, and Mr. David Golub, our chief executive officer, is a manager of GC Advisors, and each of Messrs. Lawrence Golub and David Golub owns an indirect pecuniary interest in GC Advisors.


•	Golub Capital LLC provides, and other affiliates of Golub Capital have historically provided, us with the office facilities and administrative services necessary to conduct day-to-day operations pursuant to our Administration Agreement.


•	We have entered into a license agreement with Golub Capital LLC, pursuant to which Golub Capital LLC has granted us a non-exclusive, royalty-free license to use the name “Golub Capital.”

•

Under the Staffing Agreement, Golub Capital LLC has agreed to provide GC Advisors with the resources necessary to fulfill its obligations under the Investment Advisory Agreement. The Staffing Agreement provides that Golub Capital LLC will make available to GC Advisors experienced investment professionals and provide access to the senior investment personnel of Golub Capital LLC for purposes of evaluating, negotiating, structuring, closing and monitoring our investments. The Staffing Agreement also includes a commitment that the members of GC Advisors’ investment committee will serve in such capacity. Services under the Staffing Agreement are provided on a direct cost reimbursement basis. We are not a party to the Staffing Agreement.

•

GC Advisors serves as collateral manager to the 2010 Issuer and the 2014 Issuer under the 2010 Collateral Management Agreement and 2014 Collateral Management Agreement, respectively, and receives a fee for providing these services that is offset against the base management fee payable by us under the Investment Advisory Agreement. We have entered into the Adviser Revolver with GC Advisors in order to have the ability to borrow funds on a short-term basis.

•

During calendar year 2017, the Golub Capital Employee Grant Program Rabbi Trust, or the Trust, purchased approximately $17.7 million of shares, or 955,896 shares, of our common stock from GCOP LLC, an affiliate of GC Advisors, for the purpose of awarding incentive compensation to employees of Golub Capital. During calendar year 2016, the Trust purchased approximately $1.5 million of shares, or 95,035 shares, of our common stock, for the purpose of awarding incentive compensation to employees of Golub Capital.

GC Advisors also sponsors or manages, and may in the future sponsor or manage, other investment funds, accounts or investment vehicles (together referred to as “accounts”) that have investment mandates that are similar, in whole and in part, with ours. For example, GC Advisors presently serves as the investment adviser to Golub Capital Investment Corporation and Golub Capital BDC 3, Inc., each an unlisted business development company that primarily focuses on investing in senior secured and one stop loans. In addition, our officers and directors serve in similar capacities for and Golub Capital Investment Corporation and Golub . GC Advisors and its affiliates may determine that an investment is appropriate for us Capital BDC 3, Inc. for one or more of those other accounts. In such event, depending on the availability of such investment and other appropriate factors, and pursuant to GC Advisors’ allocation policy, GC Advisors or its affiliates may determine that we should invest side-by-side with one or more other accounts. We do not intend to make any investments if they are not permitted by applicable law and interpretive positions of the SEC and its staff, or if they are inconsistent with GC Advisors’ allocation procedures.

In addition, we have adopted a formal code of ethics that governs the conduct of our and GC Advisors’ officers, directors and employees. Our officers and directors also remain subject to the duties imposed by both the 1940 Act and the General Corporation Law of the State of Delaware.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following items as critical accounting policies.

Fair Value Measurements

We value investments for which market quotations are readily available at their market quotations. However, a readily available market value is not expected to exist for many of the investments in our portfolio, and we value these portfolio investments at fair value as determined in good faith by our board of directors under our valuation policy and process.

Valuation methods may include comparisons of the portfolio companies to peer companies that are public, determination of the enterprise value of a portfolio company, discounted cash flow analysis and a market interest rate approach. The factors that are taken into account in fair value pricing investments include: available current market data, including relevant and applicable market trading and transaction comparables; applicable market yields and multiples; security covenants; call protection provisions; information rights; the nature and realizable value of any collateral; the portfolio company’s ability to make payments, its earnings and discounted cash flows and the markets in which it does business; comparisons of financial ratios of peer companies that are public; comparable merger and acquisition transactions; and the principal market and enterprise values. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we will consider the pricing indicated by the external event to corroborate the private equity valuation. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the investments may differ significantly from the values that would have been used had a readily available market value existed for such investments and may differ materially from values that may ultimately be received or settled.

Our board of directors is ultimately and solely responsible for determining, in good faith, the fair value of investments that are not publicly traded, whose market prices are not readily available on a quarterly basis or any other situation where portfolio investments require a fair value determination.

With respect to investments for which market quotations are not readily available, our board of directors undertakes a multi-step valuation process each quarter, as described below:

Our quarterly valuation process begins with each portfolio company investment being initially valued by the investment professionals of GC Advisors responsible for credit monitoring. Preliminary valuation conclusions are then documented and discussed with our senior management and GC Advisors. The audit committee of our board of directors reviews these preliminary valuations. At least once annually, the valuation for each portfolio investment is reviewed by an independent valuation firm. The board of directors discusses valuations and determines the fair value of each investment in our portfolio in good faith.

Determination of fair values involves subjective judgments and estimates. Under current accounting standards, the notes to our consolidated financial statements refer to the uncertainty with respect to the possible effect of such valuations, and any change in such valuations, on our consolidated financial statements.

We follow ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the assets or liabilities or market and the assets’ or liabilities’ complexity. Our fair value analysis includes an analysis of the value of any unfunded loan commitments. Assets and liabilities are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the transparency of the inputs to the valuation of the asset or liability as of the measurement date. The three levels are defined as follows:

Level 1: Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the three months ended December 31, 2017 and 2016. The following section describes the valuation techniques used by us to measure different assets and liabilities at fair value and includes the level within the fair value hierarchy in which the assets and liabilities are categorized.

Valuation of Investments

Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by our board of directors, based on input of management, the audit committee and independent valuation firms that have been engaged at the direction of our board of directors to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing twelve-month period under a valuation policy and a consistently applied valuation process. This valuation process is conducted at the end of each fiscal quarter, with approximately 25% (based on the number of portfolio companies) of our valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. As of December 31, 2017 and September 30, 2017, with the exception of money market funds included in cash and cash equivalents and restricted cash and cash equivalents (Level 1 investments) and investments measured at fair value using the NAV, all investments were valued using Level 3 inputs of the fair value hierarchy.

When determining fair value of Level 3 debt and equity investments, we may take into account the following factors, where relevant: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities, and changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s EBITDA. A portfolio company’s EBITDA may include pro-forma adjustments for items such as acquisitions, divestitures, or expense reductions. The enterprise value analysis is performed to determine the value of equity investments and to determine if debt investments are credit impaired. If debt investments are credit impaired, we will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, we use a market interest rate yield analysis to determine fair value.

In addition, for certain debt investments, we may base our valuation on indicative bid and ask prices provided by an independent third party pricing service. Bid prices reflect the highest price that we and others may be willing to pay. Ask prices represent the lowest price that we and others may be willing to accept. We generally use the midpoint of the bid/ask range as our best estimate of fair value of such investment.

Due to the inherent uncertainty of determining the fair value of Level 3 investments that do not have a readily available market value, the fair value of the investments may differ significantly from the values that would have been used had a market existed for such investments and may differ materially from the values that may ultimately be received or settled. Further, such investments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded instruments. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we may realize significantly less than the value at which such investment had previously been recorded.

Our investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

Valuation of Other Financial Assets and Liabilities

Fair value of our debt is estimated using Level 3 inputs by discounting remaining payments using comparable market rates or market quotes for similar instruments at the measurement date, if available.

Revenue Recognition:

Our revenue recognition policies are as follows:

Investments and Related Investment Income: Interest income is accrued based upon the outstanding principal amount and contractual interest terms of debt investments. Premiums, discounts, and origination fees are amortized or accreted into interest income over the life of the respective debt investment. For investments with contractual PIK interest, which represents contractual interest accrued and added to the principal balance that generally becomes due at maturity, we do not accrue PIK

interest if the portfolio company valuation indicates that the PIK interest is not likely to be collectible. In addition, we may generate revenue in the form of amendment, structuring or due diligence fees, fees for providing managerial assistance, consulting fees and prepayment premiums on loans and record these fees as fee income when received. Loan origination fees, original issue discount and market discount or premium are capitalized, and we accrete or amortize such amounts as interest income. We record prepayment premiums on loans as fee income. Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Distributions received from LLC and limited partnership, or LP, investments are evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, we will not record distributions from equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment.

We account for investment transactions on a trade-date basis. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the cost basis of investment, without regard to unrealized gains or losses previously recognized. We report changes in fair value of investments from the prior period that is measured at fair value as a component of the net change in unrealized appreciation (depreciation) on investments in our Consolidated Statements of Operations.

Non-accrual: Loans may be left on accrual status during the period we are pursuing repayment of the loan. Management reviews all loans that become past due 90 days or more on principal and interest or when there is reasonable doubt that principal or interest will be collected for possible placement on non-accrual status. We generally reverse accrued interest when a loan is placed on non-accrual. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment. We restore non-accrual loans to accrual status when past due principal and interest is paid and, in our management’s judgment, are likely to remain current. The total fair value of our non-accrual loans was $1.8 million as of December 31, 2017 and $3.0 million as of September 30, 2017.

Partial loan sales: We follow the guidance in ASC Topic 860, when accounting for loan participations and other partial loan sales. Such guidance requires a participation or other partial loan sale to meet the definition of a “participating interest”, as defined in the guidance, in order for sale treatment to be allowed. Participations or other partial loan sales that do not meet the definition of a participating interest remain on our statements of assets and liabilities and the proceeds are recorded as a secured borrowing until the definition is met. Secured borrowings are carried at fair value to correspond with the related investments, which are carried at fair value.

Income taxes: See “Consolidated Results of Operations - Expenses - Excise Tax Expense.”

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are subject to financial market risks, including changes in interest rates. Many of the loans in our portfolio have floating interest rates, and we expect that our loans in the future may also have floating interest rates. These loans are usually based on a floating LIBOR and typically have interest rate reset provisions that adjust applicable interest rates under such loans to current market rates on a quarterly basis. The loans that are subject to the floating LIBOR are also subject to a minimum base rate, or floor, that we charge on our loans if the current market rates are below the respective floors. As of December 31, 2017 and September 30, 2017, the weighted average LIBOR floor on the loans subject to floating interest rates was 1.02% and 1.03%, respectively. Prior to their redemption on October 20, 2016, the Class A 2010 Notes issued as part of the 2010 Debt Securitization had floating interest rate provisions based on three-month LIBOR that reset quarterly as do the Class A-Refi 2010 Notes issued in connection with the refinancing of the 2010 Debt Securitization. In addition, the Class A-1, A-2 and B 2014 Notes issued as part of the 2014 Debt Securitization have floating interest rate provisions based on three-month LIBOR that reset quarterly and the Credit Facility has a floating interest rate provision based on one-month LIBOR that resets daily. We expect that other credit facilities into which we enter in the future may have floating interest rate provisions.

Assuming that the interim and unaudited Consolidated Statement of Financial Condition as of December 31, 2017 were to remain constant and that we took no actions to alter interest rate sensitivity as of such date, the following table shows the annualized impact of hypothetical base rate changes in interest rates.



Change in interest rates	Increase (decrease) in interest income			Increase (decrease) in interest expense			Net increase (decrease) in investment income
	(In thousands)
Down 25 basis points	$	(3,939	)	$	(1,403	)	$	(2,536	)
Up 50 basis points	7,886			2,807			5,079
Up 100 basis points	15,773			5,613			10,160
Up 150 basis points	23,660			8,420			15,240
Up 200 basis points	31,546			11,226			20,320

Although we believe that this analysis is indicative of our sensitivity to interest rate changes as of December 31, 2017, it does not adjust for changes in the credit market, credit quality, the size and composition of the assets in our portfolio and other business developments, including borrowings under the Debt Securitizations and the Credit Facility, or other borrowings, that could affect net increase in net assets resulting from operations, or net income. Accordingly, we can offer no assurances that actual results would not differ materially from the analysis above.

We may in the future hedge against interest rate fluctuations by using standard hedging instruments such as interest rate swaps, futures, options and forward contracts to the limited extent permitted under the 1940 Act and applicable commodities laws. While hedging activities may insulate us against adverse changes in interest rates, they may also limit our ability to participate in the benefits of lower interest rates with respect to the investments in our portfolio with fixed interest rates.

Item 4: Controls and Procedures.

As of December 31, 2017 (the end of the period covered by this report), management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act). Based on that evaluation, our management, including the chief executive officer and chief financial officer, concluded that, at the end of such period, our disclosure controls and procedures were effective and provided reasonable assurance that information required to be disclosed in our periodic SEC filings is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in the Company’s periodic reports. There has not been any change in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
