(5) Investment is an SPV that holds multiple forward agreements that represent common shares of the indicated portfolio company. Forward contracts involve the future delivery of shares of a portfolio company upon such securities becoming freely transferable or the removal of restrictions on transfer. The aggregate total of the forward contracts for each SPV represents less than 5% of the Company’s net assets. The counterparties to the forward contracts are the shareholders of the private company who own the restricted shares. The Company does not have information as to the identities of the specific counterparties (the shareholders of the private company); however, counterparty risk is mitigated by the fact that there is not a single counterparty on the opposite side of the forward contracts and the sole obligation of the counterparties is to transfer shares following such time as the shares become freely transferable.
