1 Non-income producing. 2 These securities are defined as Level 2 securities due to fair value being based on quoted prices for similar securities. 3 All or a portion of these securities were pledged as collateral in connection with the Fund’s revolving credit agreement at September 30, 2017. Total market value of pledged securities at September 30, 2017, was $83,116,756. 4 At September 30, 2017, a portion of these securities were rehypothecated in connection with the Fund’s revolving credit agreement in the aggregate amount of $39,074,097. 5 Securities for which market quotations are not readily available represent 0.1% of net assets. These securities have been valued at their fair value under procedures approved by the Fund’s Board of Directors. These securities are defined as Level 3 securities due to the use of significant unobservable inputs in the determination of fair value. 6 Includes securities first acquired in 2017 and less than 1% of net assets.

TAX INFORMATION: The cost of total investments for Federal income tax purposes was $369,508,185. At September 30, 2017, net unrealized appreciation for all securities was $76,780,294, consisting of aggregate gross unrealized appreciation of $125,700,762 and aggregate gross unrealized depreciation of $48,920,468. The primary cause of the difference between book and tax basis cost is the timing of the recognition of losses on securities sold.

Valuation of Investments:
Investment transactions are accounted for on the trade date. Securities are valued as of the close of trading on the New York Stock Exchange (NYSE) (generally 4:00 p.m. Eastern time) on the valuation date. Securities that trade on an exchange, and securities traded on Nasdaq’s Electronic Bulletin Board, are valued at their last reported sales price or Nasdaq official closing price taken from the primary market in which each security trades or, if no sale is reported for such day, at their highest bid price. Other over-the-counter securities for which market quotations are readily available are valued at their highest bid price, except in the case of some bonds and other fixed income securities which may be valued by reference to other securities with comparable ratings, interest rates and maturities, using established independent pricing services. The Fund values its non-U.S. dollar denominated securities in U.S. dollars daily at the prevailing foreign currency exchange rates as quoted by a major bank. Securities for which market quotations are not readily available are valued at their fair value in accordance with the provisions of the 1940 Act, under procedures approved by the Fund’s Board of Directors, and are reported as Level 3 securities. As a general principle, the fair value of a security is the amount which the Fund might reasonably expect to receive for the security upon its current sale. However, in light of the judgment involved in fair valuations, there can be no assurance that a fair value assigned to a particular security will be the amount which the Fund might be able to receive upon its current sale. In addition, if, between the time trading ends on a particular security and the close of the customary trading session on the NYSE, events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. The Fund uses an independent pricing service to provide fair value estimates for relevant non-U.S. equity securities on days when the U.S. market volatility exceeds a certain threshold. This pricing service uses proprietary correlations it has developed between the movement of prices of non-U.S. equity securities and indices of U.S.-traded securities, futures contracts and other indications to estimate the fair value of relevant non-U.S. securities. When fair value pricing is employed, the prices of securities used by the Fund may differ from quoted or published prices for the same security. Investments in money market funds are valued at net asset value per share.

Various inputs are used in determining the value of the Fund’s investments, as noted above. These inputs are summarized in the three broad levels below:
Level 1  –   quoted prices in active markets for identical securities. Level 2  –  
other significant observable inputs (including quoted prices for similar securities, foreign securities that may be fair valued and repurchase agreements). The table below includes all Level 2 securities. Level 2 securities with values based on quoted prices for similar securities are noted in the Schedule of Investments.
Level 3  –  
significant unobservable inputs (including last trade price before trading was suspended, or at a discount thereto for lack of marketability or otherwise, market price information regarding other securities, information received from the company and/or published documents, including SEC filings and financial statements, or other publicly available information).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following is a summary of the inputs used to value the Fund’s investments as of September 30, 2017. For a detailed breakout of common stocks by sector classification, please refer to the Schedule of Investments.
    Level 1   Level 2   Level 3   Total   Common Stocks   $402,015,593   $11,380,086   $241,800   $413,637,479 Cash Equivalents     32,651,000     32,651,000

Certain securities have transferred in and out of Level 1 and Level 2 measurements during the reporting period. The Fund recognizes transfers between levels as of the end of the reporting period. For the nine months ended September 30, 2017, securities valued at $2,304,666 were transferred from Level 1 to Level 2 and securities valued at $20,298,987 were transferred from Level 2 to Level 1 within the fair value hierarchy.

The following table summarizes the valuation techniques used and unobservable inputs approved by the Valuation Committee to determine the fair value of certain, material Level 3 investments. The table does not include Level 3 investments with values derived utilizing prices from prior transactions or third party pricing information with adjustments (e.g. broker quotes, pricing services, net asset values).

This column represents the directional change in the fair value of the Level 3 investments that would result in an increase from the corresponding unobservable input. A decrease to the unobservable input would have the opposite effect. Significant increases and decreases in these unobservable inputs in isolation could result in significantly higher or lower fair value measurements.

Repurchase Agreements:
The Fund may enter into repurchase agreements with institutions that the Fund’s investment adviser has determined are creditworthy. The Fund restricts repurchase agreements to maturities of no more than seven days. Securities pledged as collateral for repurchase agreements, which are held until maturity of the repurchase agreements, are marked-to-market daily and maintained at a value at least equal to the principal amount of the repurchase agreement (including accrued interest). Repurchase agreements could involve certain risks in the event of default or insolvency of the counter-party, including possible delays or restrictions upon the ability of the Fund to dispose of its underlying securities. The remaining contractual maturity of the repurchase agreement held by the Fund at September 30, 2017 is overnight and continuous.
  Borrowings:
The Fund is party to a revolving credit agreement (the credit agreement) with BNP Paribas Prime Brokerage International, Limited (BNPPI). As of September 30, 2017, the Fund has outstanding borrowings of $45,000,000. During the period ended September 30, 2017, the Fund borrowed an average daily balance of $45,000,000. The Fund pays a commitment fee of 0.50% per annum on the unused portion of the credit agreement. The credit agreement has a 360-day rolling term that resets daily; however, if the Fund exceeds certain net asset value triggers, the credit agreement may convert to a 60-day rolling term that resets daily. The Fund is required to pledge portfolio securities as collateral in an amount up to two times the loan balance outstanding or as otherwise required by applicable regulatory standards and has granted a security interest in the securities pledged to, and in favor of, BNPPI as security for the loan balance outstanding. If the Fund fails to meet certain requirements, or maintain other financial covenants required under the credit agreement, the Fund may be required to repay immediately, in part or in full, the loan balance outstanding under the credit agreement which may necessitate the sale of portfolio securities at potentially inopportune times. BNPPI may terminate the credit agreement upon certain ratings downgrades of its corporate parent, which would result in the Fund’s entire loan balance becoming immediately due and payable. The occurrence of such ratings downgrades may necessitate the sale of portfolio securities at potentially inopportune times. The credit agreement also permits, subject to certain conditions, BNPPI to rehypothecate portfolio securities pledged by the Fund up to the amount of the loan balance outstanding. The Fund continues to receive payments in lieu of dividends and interest on rehypothecated securities. The Fund also has the right under the credit agreement to recall the rehypothecated securities from BNPPI on demand. If BNPPI fails to deliver the recalled security in a timely manner, the Fund is compensated by BNPPI for any fees or losses related to the failed delivery or, in the event a recalled security is not returned by BNPPI, the Fund, upon notice to BNPPI, may reduce the loan balance outstanding by the value of the recalled security failed to be returned. The Fund receives a portion of the fees earned by BNPPI in connection with the rehypothecation of portfolio securities.
