(2)Cash equivalents represent investment in a collective short term investment fund, which is a cash sweep for uninvested cash that earns interest monthly. For these investments, book value is assumed to equal fair value due to the short duration of the investment term.

(3)Represents investments in commingled funds with exposure to a variety of hedge fund strategies, which are not publicly traded and have ongoing redemption restrictions. The Company’s interest in these investments is measured at net asset value per share as a practical expedient for fair value, which is derived from the underlying asset values in these funds, only some of which represent observable inputs and quoted market prices.
