FAIR VALUE MEASUREMENTS

BBH Select Series – Mid Cap Fund (the “Fund”) is required to disclose information regarding the fair value measurements of the Fund’s assets and liabilities. 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 at the measurement date. The disclosure requirement established a three-tier hierarchy 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. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including, for example, the risk inherent in a particular valuation technique used to measure fair value, including the model and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the Fund’s own considerations about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

Authoritative guidance establishes three levels of the fair value hierarchy as follows:

— Level 1 – unadjusted quoted prices in active markets for identical assets and liabilities.

— Level 2 – significant other observable inputs (including quoted prices for similar assets and liabilities, interest rates, prepayment speeds, credit risk, etc.).

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

Inputs are used in applying the various valuation techniques and broadly refer to the assumptions that market participants use to make valuation decisions, including assumptions about risk. Inputs may include price information, specific and broad credit data, liquidity statistics, and other factors. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. However, the determination of what constitutes “observable” requires judgment by the investment adviser. The investment adviser considers observable data to be that market data which is readily available, regularly distributed or updated, reliable and verifiable, not proprietary, and provided by independent sources that are actively involved in the relevant market. The categorization of a financial instrument within the hierarchy is based upon the pricing transparency of the instrument and does not necessarily correspond to the investment adviser’s perceived risk of that instrument.

Financial assets within Level 1 are based on quoted market prices in active markets. The Fund does not adjust the quoted price for these instruments.

Financial instruments that trade in markets that are not considered to be active but are valued based on quoted market prices, dealer quotations or alternative pricing sources supported by observable inputs are classified within Level 2. These include investment-grade corporate bonds, U.S. Treasury notes and bonds, and certain non-U.S. sovereign obligations, listed equities and over-the-counter derivatives and foreign equity securities whose values could be impacted by events occurring before the Fund’s pricing time, but after the close of the securities’ primary markets and are, therefore, fair valued according to procedures adopted by the Board of Trustees. As Level 2 financial assets include positions that are not traded in active markets and/or are subject to transfer restrictions, valuations may be adjusted to reflect illiquidity and/or non-transferability, which are generally based on available market information.

Financial assets classified within Level 3 have significant unobservable inputs, as they trade infrequently. Level 3 financial assets include private equity and certain corporate debt securities.

Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon the actual sale of those investments.
