Summary of Significant Accounting Policies

a. Security Valuation:

The Fund values its securities at current market value or fair value, consistent with regulatory requirements. “Fair value” is defined in the Fund’s Valuation and Liquidity Procedures as the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants without a compulsion to transact at the measurement date.

Equity securities that are traded on an exchange are valued at the last quoted sale price on the principal exchange on which the security is traded at the “Valuation Time” subject to application, when appropriate, of the valuation factors described in the paragraph below. Under normal circumstances, the Valuation Time is as of the close of regular trading on the New York Stock Exchange (usually 4:00 p.m. Eastern Time). In the absence of a sale price, the security is valued at the mean of the bid/ask price quoted at the close on the principal exchange on which the security is traded. Securities traded on NASDAQ are valued at the NASDAQ official closing price. Closed-end funds and exchange-traded funds (“ETFs”) are valued at the market price of the security at the Valuation Time. A security using any of these pricing methodologies is determined to be a Level 1 investment.

Foreign equity securities that are traded on foreign exchanges that close prior to Valuation Time are valued by applying valuation factors to the last sale price or the mean price as noted above. Valuation factors are provided by an independent pricing service provider. These valuation factors are used when pricing the Fund’s portfolio holdings to estimate market movements between the time foreign markets close and the time the Fund values such foreign securities. These valuation factors are based on inputs such as depositary receipts, indices, futures, sector indices/ETFs, exchange rates, and local exchange opening and closing prices of each security. When prices with the application of valuation factors are utilized, the value assigned to the foreign securities may not be the same as quoted or published prices of the securities on their primary markets. A security that applies a valuation factor is determined to be a Level 2 investment because the exchange-traded price has been adjusted. Valuation factors are not utilized if the independent pricing service provider is unable to provide a valuation factor or if the valuation factor falls below a predetermined threshold; in such case, the security is determined to be a Level 1 investment.

Short-term investments are comprised of cash and cash equivalents invested in short-term investment funds which are redeemable daily. The Fund sweeps available cash into the State Street Institutional U.S. Government Money Market Fund, which has elected to qualify as a “government money market fund” pursuant to Rule 2a-7 under the Investment Company Act of 1940, and has an objective to maintain a $1.00 per share net asset value. Generally, these investment types are categorized as Level 1 investments.

In the event that a security’s market quotations are not readily available or are deemed unreliable (for reasons other than because the foreign exchange on which it trades closes before the Valuation Time), the security is valued at fair value as determined by the Fund’s Pricing Committee, taking into account the relevant factors and surrounding circumstances using valuation policies and procedures approved by the Fund’s Board of Directors. A security that has been fair valued by the Fund’s Pricing Committee may be classified as Level 2 or Level 3 depending on the nature of the inputs.

In accordance with the authoritative guidance on fair value measurements and disclosures under accounting principles generally accepted in the United States of America, the Fund discloses the fair value of its investments using a three-level hierarchy that classifies the inputs to valuation techniques used to measure the fair value. The hierarchy assigns Level 1, the highest level, measurements to valuations based upon unadjusted quoted prices in active markets for identical assets, Level 2 measurements to valuations based upon other significant observable inputs, including adjusted quoted prices in active markets for similar assets, and Level 3, the lowest level, measurements to valuations based upon unobservable inputs that are significant to the valuation. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability, which are based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the

circumstances. A financial instrument’s level within the fair value hierarchy is based upon the lowest level of any input that is significant to the fair value measurement. The three-level hierarchy of inputs is summarized below:

Level 1 — quoted prices in active markets for identical investments;

Level 2 — other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, and credit risk); or

Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

For the period ended January 31, 2018, all the investments of the Fund were Level 2. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Please refer to the Portfolio of Investments for a detailed breakdown of the security types.

For movements between the levels within the fair value hierarchy, the Fund has adopted a policy of recognizing transfers at the end of each period. The utilization of valuation factors may result in transfers between Level 1 and Level 2. For the period ended January 31, 2018, the security issued by Asahi Intecc Co. Ltd. at the value of $3,634,245 transferred from Level 1 to Level 2 because there was a valuation factor applied on January 31, 2018.

For the period ended January 31, 2018, there were no significant changes to the fair valuation methodologies.

b. Rights Issues and Warrants:

Rights issues give the right, normally to existing shareholders, to buy a proportional number of additional securities at a given price (generally at a discount) within a fixed period (generally a short-term period) and are offered at the company’s discretion. Warrants are securities that give the holder the right to buy common stock at a specified price for a specified period of time. Rights issues and warrants are speculative and have no value if they are not exercised before the expiration date. Rights issues and warrants are valued at the last sale price on the exchange on which they are traded.
