[39] The Company acquired these investments in connection with the exit of related portfolio companies. These investments provide the Company with a contractual right to receive future payments; the timing and amounts of such payments are generally based upon the achievement of certain events or metrics primarily linked to the future performance of the exited portfolio company.

[48] This investment represents a credit default swap that functions, in substance, like a credit linked note and represents a credit risk transfer for a pool of reference assets owned by a bank. The Company fully funded margin up front and in return the Company receives periodic interest payments. The Company’s risk of loss is limited to the principal amount disclosed herein. The reference assets are primarily composed of investment grade corporate debt. The Company may be exposed to counterparty risk, which could make it difficult for the Company to collect on obligations, thereby resulting in potentially significant losses. In addition, the Company only has a contractual relationship with the counterparty bank, and not with the reference obligors of the reference assets. Accordingly, the Company generally may have no right to directly enforce compliance by the reference obligors with the terms of the reference assets. The Company will not directly benefit from the reference assets and will not have the benefit of the remedies that would normally be available to a holder of such reference assets. In addition, in the event of the insolvency of the counterparty bank, the Company may be treated as a general creditor of such counterparty bank, and will not have any claim with respect to the reference assets.
