Part F of Form N-PORT was prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and in conformity

with the applicable rules and regulations of the U.S. Securities and Exchange Commission ("SEC") related to interim filings. Part

F of Form N-PORT does not include all information and footnotes required by U.S. GAAP for complete financial statements. Certain

footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or

omitted from this report pursuant to the rules of the SEC. For a full set of the Fund's notes to financial statements, please refer to

the Fund's most recently filed annual or semi-annual report.

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.

Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest

rates, credit spreads, etc.).

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.

Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest

rates, credit spreads, etc.).

Part F of Form N-PORT was prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and in conformity

with the applicable rules and regulations of the U.S. Securities and Exchange Commission ("SEC") related to interim filings. Part

F of Form N-PORT does not include all information and footnotes required by U.S. GAAP for complete financial statements. Certain

footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or

the Fund's most recently filed annual or semi-annual report.

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.

Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest

rates, credit spreads, etc.).

Level 3 – Prices are determined using significant unobservable inputs (including management's assumptions in determining the

fair value of investments).

The following table summarizes the market value of the Fund's investments as of the end of the reporting period, based on the inputs

used to value them:
