NOTES TO SCHEDULES OF INVESTMENTS

January 31, 2018 (unaudited)

 

Security Valuation–The Funds value their investments in securities and other assets and liabilities at fair value daily. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Securities traded on national exchanges or traded on the NASDAQ National Market System are valued at the last sales price as reported at the close of each business day. Securities traded on the NASDAQ Stock Market are valued at the NASDAQ official closing price. Over-the-counter securities not included in the NASDAQ National Market System and listed securities for which no sale was reported are valued at the mean of the bid and ask prices. To the extent these securities are actively traded they are categorized as Level 1 in the fair value hierarchy (described below). Debt securities are valued on the basis of evaluated prices furnished by an independent pricing service approved by the Board of Trustees or provided by securities dealers. The pricing services may use valuation models or matrix pricing, which consider: (i) yield or price with respect to bonds that are considered comparable in characteristics such as rating, interest rate and maturity date and /or (ii) quotations from bond dealers to determine current value and are categorized as Level 2 in the fair value hierarchy. Money market fund investments are valued at net asset value and are categorized as Level 1 in the fair value hierarchy. Short-term debt securities with sixty days or less to maturity are valued at amortized cost, which with accrued interest approximates fair value. The Pricing Committee of Van Eck Associates Corporation, (the “Adviser”) provides oversight of the Funds’ valuation policies and procedures, which are approved by the Funds’ Board of Trustees. Among other things, these procedures allow the Funds to utilize independent pricing services, quotations from securities dealers, and other market sources to determine fair value. The Pricing Committee convenes regularly to review the fair value of financial instruments or other assets. If market quotations for a security or other asset are not readily available, or if the Adviser believes it does not otherwise reflect the fair value of a security or asset, the security or asset will be fair valued by the Pricing Committee in accordance with the Funds’ valuation policies and procedures. The Pricing Committee employs various methods for calibrating the valuation approaches utilized to determine fair value, including a regular review of key inputs and assumptions, periodic comparisons to valuations provided by other independent pricing services, transactional back-testing and disposition analysis.
  
 Certain factors such as economic conditions, political events, market trends, the nature of and duration of any restrictions on disposition, trading in similar securities of the issuer or comparable issuers and other security specific information are used to determine the fair value of these securities. Depending on the relative significance of valuation inputs, these securities may be classified either as Level 2 or Level 3 in the fair value hierarchy. The price which the Funds may realize upon sale of an investment may differ materially from the value presented in the Schedules of Investments.
  
 The Funds utilize various methods to measure the fair value of their investments on a recurring basis, which includes a hierarchy that prioritizes inputs to valuation methods used to measure fair value. The fair value hierarchy gives highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The transfers between levels of the fair value hierarchy assume the financial instruments where transferred at the beginning of the reporting period. The three levels of the fair value hierarchy are described below:
  
 Level 1 - Quoted prices in active markets for identical securities.
  
 Level 2 - Significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
  
 Level 3 - Significant unobservable inputs (including each Fund’s own assumptions in determining the fair value of investments).
  
 A summary of the inputs, the levels used to value the Funds’ investments, and transfers between levels are located in the Schedules of Investments. Additionally, tables that reconcile the valuation of the Funds’ Level 3 investments and that present additional information about valuation methodologies and unobservable inputs, if applicable, are located in the Schedules of Investments.

 

Other–High-Yield maintains assets invested in Puerto Rican municipal securities that are currently experiencing significant financial difficulties. Particularly, the Fund may be affected by political, economic, regulatory and other developments within Puerto Rico and by the financial condition of Puerto Rico’s political subdivisions, agencies, instrumentalities and public authorities. As a result, certain securities issued by this municipality are currently considered below-investment-grade securities. The market for these investments may be limited, which may make them difficult to buy or sell. Municipal obligations issued by Puerto Rico are subject to heightened risks that may adversely affect the value of the Fund’s portfolio and the repayment of such bonds are subject to significant uncertainties. If the economic situation in Puerto Rico persists or worsens, the volatility, credit quality and performance of the Fund could be adversely affected.

 

The Adviser continues to monitor the events in Puerto Rico surrounding the debt crisis. Over the past two years, Puerto Rico has defaulted on principal and interest payments due to municipal bond holders for a number of municipal issues. In September 2017, two hurricanes caused significant structural damage to Puerto Rico and left millions without power, drinking water or cell phone service. Recovery efforts may span months or years and will put significant stress and additional uncertainty on Puerto Rico’s ability to financially recover. The Fund may continue to be impacted by the overall increase in securities in default of interest and/or principal obligations due to the debt crisis and hurricane impacts.

 

The U.S. Congress passed legislation for Puerto Rico in 2016 enabling the Governor to suspend debt service payments on general obligation bonds and other constitutionally protected debt. The U.S. Congress also passed legislation in 2016 giving Puerto Rico a stay against creditor litigation that could have triggered cuts to public service. The legislation authorized an oversight board to oversee Puerto Rico’s finances and to approve any court-supervised debt restructuring. In May 2017, the oversight board initiated a bankruptcy-like process for the general government, general obligation debt, and a number of public corporations. Over the past two years, the Puerto Rican legislation and Governor have enacted legislation or executive orders to cut costs, raise tax revenue, prioritize payments for essential services, reduce debt and restructure debt payments. Some of these actions have been opposed by bond creditors and have been blocked by the courts.
