Fair Value Measurements
The Fund's investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Adviser,
subject to the review and oversight of the Board. Fair value is defined as the price that would be received upon selling an investment
or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the
investment. U.S. GAAP establishes the three-tier hierarchy that is used to maximize the use of observable market data and minimize
the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable
inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market
data obtained from sources independent of the reporting entity. Unobservable inputs reflect management’s assumptions about the
assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information
available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.
Level 1 – Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.
