Under procedures approved by the
fund’s Board of Trustees (the Board), the investment adviser has formed a Pricing Committee to administer the pricing and valuation of portfolio securities and other assets and to ensure that prices used for
internal purposes or provided by third parties reasonably reflect fair market value. Among other things, these procedures allow the fund to utilize independent pricing services, quotations from securities and
financial instrument dealers and other market sources to determine fair value.
The fund values the securities in
its portfolio every business day. The fund uses the following policies to value various types of securities:
• Securities traded on an exchange or over-the-counter: Traded securities are valued at the closing value for the day, or, on days when no closing value has been reported, at the mean of
the most recent bid and ask quotes. Securities that are primarily traded on foreign exchanges are valued at the official closing price or the last sales price on the exchange where the securities are principally
traded with these values then translated into U.S. dollars at the current exchange rate, unless these securities are fair valued as discussed below.
• Securities for which no quoted value is available: The Board has adopted procedures to fair value the fund’s securities when market prices are not “readily available”
or are unreliable. For example, a fund may fair value a security when it is de-listed or its trading is halted or suspended; when a security’s primary pricing source is unable or unwilling to provide a price; or
when a security’s primary trading market is closed during regular market hours. The fund makes fair value determinations in good faith in accordance with the fund’s valuation procedures. The Pricing
Committee considers a number of factors, including unobservable market inputs when arriving at fair value. The Pricing Committee may employ techniques such as the review of related or comparable assets or liabilities,
related market activities, recent transactions, market multiples, book values, transactional back-testing, disposition analysis and other relevant information. The Pricing Committee regularly reviews these inputs and
assumptions to calibrate the valuations. Due to the subjective and variable nature of fair value pricing, there can be no assurance that a fund could obtain the fair value assigned to the security upon the sale of
such security. The Board convenes on a regular basis to review fair value determinations made by the fund pursuant to the valuation procedures.
• Foreign equity security fair valuation: The Board has adopted procedures to fair value foreign equity securities that are traded in markets that close prior to the fund valuing its
holdings. By fair valuing securities whose prices may have been affected by events occurring after the close of trading, the fund seeks to establish prices that investors might expect to realize upon the current sales
of these securities. This methodology is designed to deter “arbitrage” market timers, who seek to exploit delays between the change in the value of the fund’s portfolio holdings and the Net Asset
Value (NAV) of the fund’s shares, and seeks to help ensure that the prices at which the fund’s shares are purchased and redeemed are fair and do not result in dilution of shareholder interest or other harm
to shareholders. When fair value pricing is used at the open or close of a reporting period, it may cause a temporary divergence between the return of the fund and that of its comparative index or benchmark. The Board
regularly reviews fair value determinations made by the fund pursuant to these procedures.
• Cash management sweep time deposits: Balances held in cash management sweep time deposits are accounted for on a cost basis, which approximates market value.
In accordance with the authoritative
guidance on fair value measurements and disclosures under generally accepted accounting principles in the United States of America (GAAP), the fund discloses the fair value of its investments in a hierarchy that
prioritizes the significant inputs to valuation techniques used to measure the fair value. The hierarchy gives the highest priority to valuations based upon unadjusted quoted prices in active markets for identical
assets or liabilities (Level 1 measurements) and the lowest priority to valuations based upon unobservable inputs that are significant to the valuation (Level 3 measurements). If inputs used to measure the financial
instruments fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the valuation. If the fund determines that either the volume and/or level of
activity for an asset or liability has significantly decreased (from normal conditions for that asset or liability) or price quotations or observable inputs are not associated with orderly transactions, increased
analysis and management judgment will be required to estimate fair value.
The three levels of the fair value
hierarchy are as follows:
• Level 1—quoted prices in active markets for identical securities—Investments whose values are based on quoted market prices in active markets, and whose values are therefore classified as Level 1 prices, include active listed equities.
• Level 2—other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)—Investments that trade in markets that are not considered to be active, but whose values are based on quoted market prices, dealer quotations or valuations provided by alternative
pricing sources supported by observable inputs are classified as Level 2 prices. These generally include U.S. government and sovereign obligations, most government agency securities, investment-grade corporate bonds,
certain mortgage products, less liquid listed equities, and state, municipal and provincial obligations. In addition, international securities whose markets close hours before the fund values its holdings may require
fair valuations due to significant movement in the U.S. markets occurring after the daily close of the foreign markets. The Board has approved a vendor that calculates fair valuations of international equity
securities based on a number of factors that appear to correlate to the movements in the U.S. markets.
