Estimated pursuant to Rule 457(o) under the Securities Act of 1933, as amended, solely for the purpose of determining the registration fee. The proposed maximum offering price per security will be determined, from time to time, by the Registrant in connection with the sale by the Registrant of the securities registered under this registration statement. Prior to the initial filing of this registration statement, $1,045,720,000 aggregate principal amount of securities remained registered and unsold pursuant to Registration Statement No. 333-189817, which was initially filed by the Registrant on July 5, 2013. Pursuant to Rule 457(p), $142,637 of the total filing fee of $174,300 required in connection with the initial registration of $1,500,000,000 aggregate principal amount of securities under this registration statement was offset against the $142,637 filing fee associated with the unsold securities registered under Registration Statement No. 333-189817, and an additional $31,663 was paid in connection with the initial filing of this registration statement. Upon effectiveness of this registration statement, the offering of securities pursuant to Registration Statement No. 333-189817 was terminated.

(2)	Subject to Note 8 below, there is being registered hereunder an indeterminate principal amount of common stock or preferred stock, or subscription rights to purchase shares of common stock as may be sold, from time to time separately or as units in combination with other securities registered hereunder.

(3)	Includes such indeterminate number of shares of common stock as may, from time to time, be issued upon conversion or exchange of other securities registered hereunder, to the extent any such securities are, by their terms, convertible or exchangeable for common stock.

(4)	Subject to Note 8 below, there is being registered hereunder an indeterminate principal amount of warrants as may be sold, from time to time, representing rights to purchase common stock, preferred stock or debt securities.

(5)	Subject to Note 8 below, there is being registered hereunder an indeterminate principal amount of debt securities as may be sold, from time to time. If any debt securities are issued at an original issue discount, then the offering price shall be in such greater principal amount as shall result in an aggregate price to investors not to exceed $1,500,000,000.

(6)

Subject to Note 8 below, there is being registered hereunder an indeterminate principal amount of units issuable upon conversion or exchange of securities registered hereunder to the extent any such securities, are, by their terms convertible into or exchangeable for units, including upon the exercise of warrants or delivery upon settlement of purchase contracts. Each unit may consist of a combination of any two or more of the securities being registered hereby or debt obligations of third parties, including U.S. Treasury securities.

(7)

Subject to Note 8 below, there is being registered hereunder an indeterminate principal amount of purchase contracts issuable upon conversion or exchange of securities registered hereunder to the extent any such securities are, by their terms convertible into or exchangeable for purchase contracts. Each purchase contract obligates the registrant to sell, and the holder thereof to purchase, an indeterminate number of debt securities, common stock, preferred stock or other securities registered hereunder.

(8)	In no event will the aggregate offering price of all securities issued from time to time pursuant to this registration statement exceed $1,500,000,000.

(1)	In the event that the securities to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will disclose the applicable sales load.

(2)	The related prospectus supplement will disclose the estimated amount of offering expenses, the offering price and the offering expenses borne by us as a percentage of the offering price.

(3)	The expenses of the dividend reinvestment plan per share are included in “Other expenses.”

(4)	“Net assets attributable to common stock” equals net assets as of September 30, 2016.

(5)

The contractual management fee is calculated at an annual rate of 2.00% of our average total assets. Annual expenses are based on levels consistent with the quarter ended September 30, 2016, which are based on prior year amounts adjusted for new debt and equity issuances. For more detailed information about our computation of average total assets, please see Note 3 of our financial statements for the quarter ended September 30, 2016. Effective April 1, 2016 through March 31, 2017, our investment adviser has agreed to waive 25% of its base management fee so that during the waiver period the management fee is reduced from 2% to 1.5%. Such waiver is not reflected in the management fees set forth in this table or in the examples above.

(6)

Assumes that annual incentive fees earned by our investment adviser, AIM, remain consistent with our current fee structure adjusted for new debt and equity issuances, if applicable. AIM earns incentive fees consisting of two parts. The first part, which is payable quarterly in arrears, is based on our pre-incentive fee net investment income for the immediately preceding calendar quarter. Pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets at the end of the immediately preceding calendar quarter, is compared to the rate of 1.75% quarterly (7% annualized). Our net investment income used to calculate this part of the incentive fee is also included in the amount of our gross assets used to calculate the 2% base management fee (see footnote 5 above). Accordingly, we pay AIM an incentive fee as follows: (1) no incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed 1.75%, which we commonly refer to as the performance threshold; (2) 100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the performance threshold but does not exceed 2.1875% in any calendar quarter; and (3) 20% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% in any calendar quarter. These calculations are appropriately pro rated for any period of less than three months. The effect of the fee calculation described above is that if pre-incentive fee net investment income is equal to or exceeds 2.1875%, AIM will receive a fee of 20% of our pre-incentive fee net investment income for the quarter. You should be aware that a rise in the general level of interest rates can be expected to lead to higher interest rates applicable to our debt investments. Accordingly, an increase in interest rates would make it easier for us to meet or exceed the incentive fee performance threshold and may result in a substantial increase of the amount of incentive fees payable to our investment adviser with respect to pre-incentive fee net investment income. Furthermore, since the performance threshold is based on a percentage of our net asset value, decreases in our net asset value make it easier to achieve the performance threshold, holding portfolio size and other assumptions constant. The second part of the incentive fee will equal 20% of our realized capital gains for the calendar year, if any, computed net of all realized capital losses and unrealized capital depreciation (and incorporating unrealized depreciation on a gross investment-by-investment basis) and is payable in arrears at the end of each calendar year. The net incentive fees are currently entirely attributable to net investment income incentive fees.

Our interest and other debt expenses are based on borrowing levels and interest rates consistent with the levels during the quarter ended September 30, 2016, which are based on prior amounts adjusted for new debt issuances. As of September 30, 2016, we had $926 million available and $368 million in borrowings outstanding under our $1.31 billion senior secured credit facility and $1.015 billion of total debt outstanding. As of September 30, 2016, the Company had $16.3 million in standby letters of credit issued through the senior secured credit facility. The amount available for borrowing under the senior secured credit facility is reduced by any standby letters of credit issued. On April 24, 2015, the Company amended and restated the senior secured credit facility. For more information, see “Risk Factors—Risks relating to our business and structure—We fund a portion of our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” in this base prospectus.

(8)	Includes our estimated overhead expenses, including payments under the administration agreement based on our allocable portion of overhead and other expenses incurred by AIA in performing its obligations under the administration agreement. See “Management—Administration Agreement” in this base prospectus.

(9)

“Total annual expenses” as a percentage of net assets attributable to common stock are higher than the total annual expenses percentage would be for a company that is not leveraged. We borrow money to leverage our net assets and increase our total assets. The SEC requires that the “Total annual expenses” percentage be calculated as a percentage of net assets (defined as total assets less indebtedness), rather than the total assets, including assets that have been funded with borrowed monies. If the “Total annual expenses” percentage were calculated instead as a percentage of total assets, our “Total annual expenses” would be 6.04% of total assets.

•	The higher interest rates of OID and PIK instruments reflect the payment deferral and increased credit risk associated with these instruments, and OID and PIK instruments generally represent a significantly higher credit risk than coupon loans.

•	Even if the accounting conditions for income accrual are met, the borrower could still default when our actual collection is supposed to occur at the maturity of the obligation.

•	OID and PIK instruments may have unreliable valuations because their continuing accruals require continuing judgments about the collectibility of the deferred payments and the value of any associated collateral. OID and PIK income may also create uncertainty about the source of our cash distributions.

•	An election to defer PIK interest payments by adding them to loan principal increases our gross assets, thus increasing our investment adviser’s future base management fees, and increases future investment income, thus increasing our investment adviser’s future income incentive fees at a compounding rate.

•	Market prices of zero-coupon or PIK securities may be affected to a greater extent by interest rate changes and may be more volatile than securities that pay interest periodically and in cash.

•

For accounting purposes, any cash distributions to stockholders representing OID and PIK income are not treated as coming from paid-in capital, even if the cash to pay them comes from offering proceeds. As a result, despite the fact that a distribution representing OID and PIK income could be paid out of amounts invested by our stockholders, the 1940 Act does not require that stockholders be given notice of this fact by reporting it as a return of capital.

Our investments may include equity features, such as warrants or options to buy a minority interest in the portfolio company. Any warrants we receive with our debt securities generally require only a nominal cost to exercise, and thus, as a portfolio company appreciates in value, we may achieve additional investment return from this equity interest. We may structure the warrants to provide provisions protecting our rights as a minority-interest holder, as well as puts, or rights to sell such securities back to the company, upon the occurrence of specified events. In many cases, we may also seek to obtain registration rights in connection with these equity interests, which may include demand and “piggyback” registration rights.

(1)	Total amount of each class of senior securities outstanding at the end of the period presented.

(2)	The asset coverage ratio for a class of senior securities representing indebtedness is calculated as our consolidated total assets, less all liabilities and indebtedness not represented by senior securities, divided by senior securities representing indebtedness. This asset coverage ratio is multiplied by $1,000 to determine the Asset Coverage Per Unit.

Not applicable, except for with respect to the 2042 Notes, the 2043 Notes, and the Convertible Notes, as other senior securities do not have sufficient trading for an average market value per unit to be determined. The average market value per unit for each of the 2042 Notes, the 2043 Notes, and the Convertible Notes is based on the closing daily prices of such notes and is expressed per $100 of indebtedness (including for the 2042 Notes and the 2043 Notes, which were issued in $25 increments).

(5)	Included in this amount is foreign currency debt obligations as outlined in the table in note 6.

•	how it handles securities payments and notices,

•	whether it imposes fees or charges,

•	how it would handle a request for the holders’ consent, if ever required,

•	whether and how you can instruct it to send you debt securities registered in your own name so you can be a holder, if that is permitted in the future for a particular series of debt securities,

•	how it would exercise rights under the debt securities if there were a default or other event triggering the need for holders to act to protect their interests, and

•	if the debt securities are in book-entry form, how the depositary’s rules and procedures will affect these matters.

•	An investor cannot cause the debt securities to be registered in his or her name, and cannot obtain certificates for his or her interest in the debt securities, except in the special situations we describe below.

•	An investor will be an indirect holder and must look to his or her own bank or broker for payments on the debt securities and protection of his or her legal rights relating to the debt securities, as we describe under “Issuance of Securities in Registered Form” above.

---

•	An investor may not be able to sell interests in the debt securities to some insurance companies and other institutions that are required by law to own their securities in non-book-entry form.

•	An investor may not be able to pledge his or her interest in a global security in circumstances where certificates representing the debt securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective.

•	The depositary’s policies, which may change from time to time, will govern payments, transfers, exchanges and other matters relating to an investor’s interest in a global security. We and the trustee have no responsibility for any aspect of the depositary’s actions or for its records of ownership interests in a global security. We and the trustee also do not supervise the depositary in any way.

•	If we redeem less than all the debt securities of a particular series being redeemed, DTC’s practice is to determine by lot the amount to be redeemed from each of its participants holding that series.

•	An investor is required to give notice of exercise of any option to elect repayment of its debt securities, through its participant, to the applicable trustee and to deliver the related debt securities by causing its participant to transfer its interest in those debt securities, on DTC’s records, to the applicable trustee.

•	DTC requires that those who purchase and sell interests in a global security deposited in its book-entry system use immediately available funds. Your broker or bank may also require you to use immediately available funds when purchasing or selling interests in a global security.

•

Financial institutions that participate in the depositary’s book-entry system, and through which an investor holds its interest in a global security, may also have their own policies affecting payments, notices and other matters relating to the debt securities. There may be more than one financial intermediary in the chain of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.

•	if the depositary notifies us that it is unwilling, unable or no longer qualified to continue as depositary for that global security, and we do not appoint another institution to act as depositary within 60 days,

•	if we notify the trustee that we wish to terminate that global security, or

•	if an event of default has occurred with regard to the debt securities represented by that global security and has not been cured or waived; we discuss defaults later under “Events of Default.”

---

•	We do not pay the principal of, or any premium on, a debt security of the series on its due date.

•	We do not pay interest on a debt security of the series within 30 days of its due date.

•	We do not deposit any sinking fund payment in respect of debt securities of the series on its due date.

•	We remain in breach of a covenant in respect of debt securities of the series for 60 days after we receive a written notice of default stating we are in breach. The notice must be sent by either the trustee or holders of at least 25% of the principal amount of debt securities of the series.

•	We file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur.

•	Any other Event of Default in respect of debt securities of the series described in the prospectus supplement occurs.

---

•	You must give your trustee written notice that an Event of Default has occurred and remains uncured.

•	The holders of at least 25% in principal amount of all outstanding debt securities of the relevant series must make a written request that the trustee take action because of the default and must offer reasonable indemnity to the trustee against the cost and other liabilities of taking that action.

•	The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

•	The holders of a majority in principal amount of the debt securities must not have given the trustee a direction inconsistent with the above notice during that 60-day period.

•	in respect of a covenant that cannot be modified or amended without the consent of each holder.

•	Where we merge out of existence or sell our assets, the resulting entity must agree to be legally responsible for our obligations under the debt securities.

•

The merger or sale of assets must not cause a default on the debt securities and we must not already be in default (unless the merger or sale would cure the default). For purposes of this no-default test, a default would include an Event of Default that has occurred and has not been cured, as described under “Events of Default” above. A default for this purpose would also include any event that would be an Event of Default if the requirements for giving us a notice of default or our default having to exist for a specific period of time were disregarded.

•

Under the indenture, no merger or sale of assets may be made if as a result any of our property or assets or any property or assets of one of our subsidiaries, if any, would become subject to any mortgage, lien or other encumbrance unless either (i) the mortgage, lien or other encumbrance could be created pursuant to the limitation on liens covenant in the indenture (see “Indenture Provisions—Limitation on Liens” below) without equally and ratably securing the indenture securities or (ii) the indenture securities are secured equally and ratably with or prior to the debt secured by the mortgage, lien or other encumbrance.

•	We must deliver certain certificates and documents to the trustee.

•	We must satisfy any other requirements specified in the prospectus supplement relating to a particular series of debt securities.

---

•	change the stated maturity of the principal of, or interest on, a debt security;

•	reduce any amounts due on a debt security;

•	reduce the amount of principal payable upon acceleration of the maturity of a security following a default;

•	adversely affect any right of repayment at the holder’s option;

•	change the place (except as otherwise described in the prospectus or prospectus supplement) or currency of payment on a debt security;

•	impair your right to sue for payment;

•	modify any other aspect of the provisions of the indenture dealing with supplemental indentures, modification and waiver of past defaults, changes to the quorum or voting requirements or the waiver of certain covenants; and

•	change any obligation we have to pay additional amounts.

•	If the change affects only one series of debt securities, it must be approved by the holders of a majority in principal amount of that series.

•	If the change affects more than one series of debt securities issued under the same indenture, it must be approved by the holders of a majority in principal amount of all of the series affected by the change, with all affected series voting together as one class for this purpose.

---

•	For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of these debt securities were accelerated to that date because of a default.

•	For debt securities whose principal amount is not known (for example, because it is based on an index), we will use a special rule for that debt security described in the prospectus supplement.

•	For debt securities denominated in one or more foreign currencies, we will use the U.S. dollar equivalent.

•	If the debt securities of the particular series are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of such debt securities a combination of money and United States government or United States government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates.

•	We must deliver to the trustee a legal opinion of our counsel confirming that, under current United States federal income tax law, we may make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves at maturity.

•	If the debt securities of the particular series are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of such debt securities a combination of money and United States government or United States government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates.

•

We must deliver to the trustee a legal opinion confirming that there has been a change in current United States federal tax law or an IRS ruling that allows us to make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves at maturity. Under current United States federal tax law, the deposit and our legal release from the debt securities would be treated as though we paid you your share of the cash and notes or bonds at the time the cash and notes or bonds were deposited in trust in exchange for your debt securities and you would recognize gain or loss on the debt securities at the time of the deposit.

•	We must deliver to the trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act, as amended, and a legal opinion and officers’ certificate stating that all conditions precedent to defeasance have been complied with.

•

The settlement rate, which is a number that, when multiplied by the stated amount of a purchase contract, determines the number of securities that we or a trust will be obligated to sell and a holder will be obligated to purchase under that purchase contract upon payment of the stated amount of that purchase contract. The settlement rate may be determined by the application of a formula specified in the prospectus supplement. If a formula is specified, it may, subject to compliance with the 1940 Act, be based on the market price of such securities over a specified period or it may be based on some other reference statistic.

•	Whether the purchase contracts will be issued separately or as part of units consisting of a purchase contract and an underlying security with an aggregate principal amount equal to the stated amount.

Denotes investments in which we are deemed to exercise a controlling influence over the management or policies of a company, as defined in the 1940 Act, due to beneficially owning, either directly or through one or more controlled companies, more than 25% of the outstanding voting securities of the investment.

(7)	Substantially all securities are pledged as collateral to our multi-currency revolving credit facility (the “Senior Secured Facility” as defined in Note 6). As such, these securities are not available as collateral to our general creditors.

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

Such differences may include level of subordination, call protection and pricing, and differing interest rate characteristics, among other factors. Such factors are usually considered in the determination of fair values.

Investments that the Company has determined are not “qualifying assets” under Section 55(a) of the 1940 Act. Under the 1940 Act, we may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets. The status of these assets under the 1940 Act is subject to change. The Company monitors the status of these assets on an ongoing basis.

(18)	In addition to the interest earned based on the stated rate of this loan, the Company may be entitled to receive additional interest as a result of its arrangement with other lenders in a syndication.

(19)	This investment represents a leveraged subordinated interest in a trust that holds one foreign currency denominated bond and a derivative instrument.

Generally, the interest rate on variable interest rate investments is at benchmark rate plus spread. The borrower has an option to choose the benchmark rate, such as the London Interbank Offered Rate (“LIBOR”), the Euro Interbank Offered Rate (“EURIBOR”), the federal funds rate or the prime rate. The spread may change based on the type of rate used. The terms in the Schedule of Investments disclose the actual interest rate in effect as of the reporting period. LIBOR loans are typically indexed to 30-day, 90-day, 180-day or 360-day LIBOR rates (1M L, 3M L, 6M L or 12M L, respectively), at the borrower’s option. Both LIBOR and prime loans may be subject to interest floors. As of March 31, 2016, rates for 1M L, 3M L, 6M L and 12M L are 0.43725%, 0.6286%, 0.8997% and 1.2134%, respectively.

(21)	The rates associated with these undrawn committed revolvers and delayed draw term loans represent rates for commitment and unused fees.

(22)

The collateralized loan obligation (“CLO”) equity investments are entitled to recurring distributions which are generally equal to the excess cash flow generated from the underlying investments after payment of the contractual payments to debt holders and fund expenses. The current estimated yield is based on the current projections of this excess cash flow taking into account assumptions such as expected prepayments, losses and future reinvestment rates. These assumptions are periodically reviewed and adjusted. Ultimately, the actual yield may be higher or lower than the estimated yield if actual results differ from those used for the assumptions.

(23)

As of March 31, 2016, the Company had the following commitments to fund various revolving and delayed draw senior secured and subordinated loans, including commitments to issue letters of credit through a financial intermediary on behalf of certain portfolio companies. Such commitments are subject to the satisfaction of certain conditions set forth in the documents governing these loans and letters of credit and there can be no assurance that such conditions will be satisfied. See Note 8 to the financial statements for further information on revolving and delayed draw loan commitments, including commitments to issue letters of credit, related to certain portfolio companies.

Generally, the interest rate on floating interest rate investments is at benchmark rate plus spread. The borrower has an option to choose the benchmark rate, such as the London Interbank Offered Rate (“LIBOR”), the Euro Interbank Offered Rate (“EURIBOR”), the federal funds rate or the prime rate. The spread may change based on the type of rate used. The terms in the Schedule of Investments disclose the actual interest rate in effect as of the reporting period. LIBOR loans are typically indexed to 30-day, 90-day, 180-day or 360-day LIBOR rates (1M L, 3M L, 6M L or 12M L, respectively), and EURIBOR loans are typically indexed to 90-day EURIBOR rates (3M E), at the borrower’s option. LIBOR, EURIBOR, and prime loans may be subject to interest floors. As of September 30, 2016, rates for 1M L, 3M L, 6M L, 12M L, 3M E, and prime are 0.53%, 0.85%, 1.24%, 1.55%, (0.30%), and 3.50% – 4.00%, respectively.

(22)

The collateralized loan obligation (“CLO”) equity investments are entitled to recurring distributions which are generally equal to the excess cash flow generated from the underlying investments after payment of the contractual payments to debt holders and fund expenses. The current estimated yield is based on the current projections of this excess cash flow taking into account assumptions such as expected prepayments, losses and future reinvestment rates. These assumptions are periodically reviewed and adjusted. Ultimately, the actual yield may be higher or lower than the estimated yield if actual results differ from those used for the assumptions.

(7)	Substantially all securities are pledged as collateral to our multi-currency revolving credit facility (the “Senior Secured Facility” as defined in Note 6). As such, these securities are not available as collateral to our general creditors.

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

---

(9)	As a result of the amendment of our Senior Secured Facility on April 24, 2015, the industry classifications were updated in the Schedule of Investments as of March 31, 2016.

(10)	The percentage is calculated over net assets.

(11)	These securities are exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be resold in transactions that are exempt from registration, normally to qualified institutional buyers.

(12)	Denominated in USD unless otherwise noted, Euro (“€”), British Pound (“£”), and Canadian Dollar (“C$”).

(13)	Non-income producing security.

(14)	Non-accrual status (Note 2).

(15)	The investment has a put option attached to it and the combined instrument has been recorded in its entirety at fair value as a hybrid instrument in accordance with ASC 815-15-25-4 with subsequent changes in fair value charged or credited to investment gains/losses for each period.

(16)	Denotes debt securities where the Company owns multiple tranches of the same broad asset type but whose security characteristics differ. Such differences may include level of subordination, call protection and pricing, and differing interest rate characteristics, among other factors. Such factors are usually considered in the determination of fair values.

(17)

Investments that the Company has determined are not “qualifying assets” under Section 55(a) of the 1940 Act. Under the 1940 Act, we may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets. The status of these assets under the 1940 Act is subject to change. The Company monitors the status of these assets on an ongoing basis.

(18)	In addition to the interest earned based on the stated rate of this loan, the Company may be entitled to receive additional interest as a result of its arrangement with other lenders in a syndication.

(19)	This investment represents a leveraged subordinated interest in a trust that holds one foreign currency denominated bond and a derivative instrument.

(20)

Generally, the interest rate on variable interest rate investments is at benchmark rate plus spread. The borrower has an option to choose the benchmark rate, such as the London Interbank Offered Rate (“LIBOR”), the Euro Interbank Offered Rate (“EURIBOR”), the federal funds rate or the prime rate. The spread may change based on the type of rate used. The terms in the Schedule of Investments disclose the actual interest rate in effect as of the reporting period. LIBOR loans are typically indexed to 30-day, 90-day, 180-day or 360-day LIBOR rates (1M L, 3M L, 6M L or 12M L, respectively), at the borrower’s option. Both LIBOR and prime loans may be subject to interest floors. As of March 31, 2016, rates for 1M L, 3M L, 6M L and 12M L are 0.43725%, 0.6286%, 0.8997% and 1.2134%, respectively.

(21)	The rates associated with these undrawn committed revolvers and delayed draw term loans represent rates for commitment and unused fees.

(22)

The collateralized loan obligation (“CLO”) equity investments are entitled to recurring distributions which are generally equal to the excess cash flow generated from the underlying investments after payment of the contractual payments to debt holders and fund expenses. The current estimated yield is based on the current projections of this excess cash flow taking into account assumptions such as expected prepayments, losses and future reinvestment rates. These assumptions are periodically reviewed and adjusted. Ultimately, the actual yield may be higher or lower than the estimated yield if actual results differ from those used for the assumptions.

(23)

As of March 31, 2016, the Company had the following commitments to fund various revolving and delayed draw senior secured and subordinated loans, including commitments to issue letters of credit through a financial intermediary on behalf of certain portfolio companies. Such commitments are subject to the satisfaction of certain conditions set forth in the documents governing these loans and letters of credit and there can be no assurance that such conditions will be satisfied. See Note 8 to the financial statements for further information on revolving and delayed draw loan commitments, including commitments to issue letters of credit, related to certain portfolio companies.
