Loans are subject to the risk of payment defaults of scheduled interest or principal. Such non-payment could result in a reduction of income, a reduction in the value of the investment and a potential decrease in the net asset value of the Fund. Risk of loss of income is generally higher for unsecured loans or debt, which are not backed by a security interest in any specific collateral. There can be no assurance that the liquidation of any collateral securing a Loan would satisfy the Borrower’s obligation to the Fund in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated.

Second lien loans generally are subject to similar risks as those associated with investments in first lien loans except that such loans are subordinated in payment and/or lower in lien priority to first lien holders. In the event of default on a second lien loan, the first priority lien holder has first claim to the underlying collateral of the loan. Second lien loans are subject to the additional risk that the cash flow of the Borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to senior obligations of the Borrower. At March 31, 2015, BGB had invested $136,507,102 in second lien secured loans. 

Loans can be rated below investment grade or may also be unrated. As a result, the risks associated with Loans may be similar to the risks of other below investment grade securities, although they are senior and secured in contrast to other below investment grade securities, which are often subordinated or unsecured. BGB typically invests in Loans rated below investment grade, which are considered speculative because of the credit risk of their issuers. Such companies are more likely than investment grade issuers to default on their payments of interest and principal owed to BGB, and such defaults could reduce net asset value and income distributions. The amount of public information available with respect to below investment grade loans will generally be less extensive than that available for registered or exchange-listed securities. In evaluating the creditworthiness of Borrowers, the Adviser will consider, and may rely in part, on analyses performed by others. The Adviser’s established best execution procedures and guidelines require trades to be placed for execution only with broker-dealer counterparties approved by the Counterparty and Liquidity Sub-Committee of the Adviser. The factors considered by the Counterparty and Liquidity Sub-Committee when selecting and approving brokers and dealers include, but are not limited to: (i) quality, accuracy, and timeliness of execution, (ii) review of the reputation, financial strength and stability of the financial institution, (iii) willingness and ability of the counterparty to commit capital, (iv) ongoing reliability and (v) access to underwritten offerings and secondary markets. The Counterparty and Liquidity Sub-Committee regularly reviews each broker-dealer counterparty based on the foregoing factors.

BGB may acquire Loans through assignments or participations. BGB typically acquires these Loans through assignment, and if BGB acquires a Loan through participation, it will seek to elevate a participation interest into an assignment as soon as practicably possible. The purchaser of an assignment typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the purchaser’s rights can be more restricted than those of the assigning institution, and BGB may not be able to unilaterally enforce all rights and remedies under the Loan and with regard to any associated collateral. A participation typically results in a contractual relationship only with the institution participating out the interest, not with the Borrower. Sellers of participations typically include banks, broker-dealers, other financial institutions and lending institutions. The Adviser has adopted best execution procedures and guidelines to mitigate credit and counterparty risk in the atypical situation when BGB must acquire a Loan through a participation. BGB had no outstanding participations as of March 31, 2015.

NOTE 4. LEVERAGE

The Fund entered into a Credit Agreement (the "Agreement") with a bank to borrow money pursuant to a 364‐day revolving line of credit ("Leverage Facility") dated December 21, 2012, as amended at December 20, 2013 and December 19, 2014, to borrow up to a limit of $425 million. Borrowings under the Agreement are secured by the assets of the Fund. Interest is charged at a rate of 0.75% above LIBOR, the period commencing on the date of the making of such LIBOR Loan (or the last date upon which any other Loan was converted to, or continued as, such LIBOR Loan) and ending on the numerically corresponding day in the calendar month that is one (1) week or one (1), two (2), three (3), six (6) or nine (9) months thereafter, as the Fund may elect, or such other periods as the lender may agree in its sole and absolute discretion. Under the terms of the Agreement, the Fund must pay a commitment fee on any undrawn amounts. The commitment fee payable is 0.15% on the undrawn amounts when drawn amounts exceed 50% of the borrowing limit and 0.25% on the undrawn amounts at any other time. Interest and fees are payable quarterly. The Fund may elect to extend the Agreement for a further 364‐day period with the consent of the lending bank. At March 31, 2015, BGB had borrowings outstanding under its Leverage Facility of $389.5 million, at an interest rate of 0.93%. Due to the short term nature of the Agreement, face value approximates fair value at March 31, 2015. This fair value is based on Level 2 inputs under the three‐tier fair valuation hierarchy (see Note 2). For the quarter ended March 31, 2015, the average borrowings under BGB's Leverage Facility and the average interest rate were $389,500,000 and 0.92%, respectively.

---

Under the Agreement, the Fund has agreed to certain covenants and additional investment limitations while the leverage is outstanding. The Fund agreed to maintain asset coverage of three times over borrowings. Compliance with the investment restrictions and calculations are performed by the Fund's custodian. As of March 31, 2015, the Fund was in compliance with all required investment limitations and asset coverage requirements related to its leverage.

The use of borrowings to leverage the common shares of the Fund can create risks. Changes in the value of the Fund's portfolio, including securities bought with the proceeds of leverage, are borne entirely by the holders of common shares of the Fund. All costs and expenses related to any form of leverage used by the Fund are borne entirely by common shareholders. If there is a net decrease or increase in the value of the Fund's investment portfolio, the leverage may decrease or increase, as the case may be, the net asset value per common share to a greater extent than if the Fund did not utilize leverage. During periods when BGB is using leverage, the fees paid to the Adviser for advisory services and to ALPS for administrative services are higher than if the Fund did not use leverage because the fees paid are calculated on the basis of the Fund's Managed Assets, which include the assets purchased through leverage. As of March 31, 2015, BGB's leverage represented 32.29% of the Fund’s Managed Assets.

NOTE 5.  UNREALIZED APPRECIATION/(DEPRECIATION)

On March 31, 2015, based on cost of $1,187,161,663 for federal income tax purposes, aggregate gross unrealized appreciation for all securities in which there was an excess of value over tax cost was $13,338,186 and aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over value was $35,138,041, resulting in net unrealized depreciation of $21,799,855.
