Securities Valuation

The Funds utilize various methods to measure the fair value of most of its investments on a recurring basis. GAAP establishes a framework for measuring fair value and providing related disclosures. Broadly, the framework requires fair value to be determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. In the absence of active markets for the identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information that is consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date. It also establishes a three-level valuation hierarchy based upon observable and non-observable inputs.

Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. Preference is given to observable inputs. These two types of inputs create the following fair value hierarchy:

Level 1—Quoted prices for identical investments in active markets.

Level 2—Quoted prices for similar investments in active markets; quoted prices for identical or similar investments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3—Significant inputs to the valuation model are unobservable.

Policies and procedures are maintained to value investments using the best and most relevant data available. In addition, pricing vendors are utilized to assist in valuing investments. GEAM performs periodic reviews of the methodologies used by independent pricing services including price validation of individual securities.

Fair Value Measurement

The following section describes the valuation methodologies the Funds use to measure different financial investments at fair value.

A Fund’s portfolio securities are valued generally on the basis of market quotations. Equity securities generally are valued at the last reported sales price on the primary market in which they are traded. Portfolio securities listed on NASDAQ are valued using the NASDAQ Official Closing Price, Level 1 securities primarily include publicly-traded equity securities which may not necessarily represent the last sale price. If no sales occurred on the exchange or NASDAQ that day, the portfolio security generally is valued using the last reported bid price. In those circumstances the Fund classifies the investment securities in Level 2.

Debt securities (other than short-term securities described below) generally are valued at an evaluated bid as reported by an independent pricing service. Municipal obligations are valued at the quoted bid prices, when available. The pricing vendor uses various pricing models for each asset class that are consistent with what other market participants would use. The inputs and assumptions to the model of the pricing vendor are derived from market observable sources including: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and other market related data. Since many fixed income securities do not trade on a daily basis, the methodology of the pricing vendor uses available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. The pricing vendor considers all available market observable inputs in determining the evaluation for a security. Thus, certain securities may not be priced using quoted prices, but rather determined from market observable information. These investments are included in Level 2 and primarily comprise our portfolio of corporate fixed income, government, mortgage and asset-backed securities.

In the absence of a reliable price from such a pricing service, debt securities may be valued based on dealer supplied valuations or quotations. In these infrequent circumstances, pricing vendors may provide the Funds with valuations that are based on significant unobservable inputs, and in those circumstances we classify the investment securities in Level 3.

The Funds use non-binding broker quotes as the primary basis for valuation when there is limited, or no, relevant market activity for a specific investment or for other investments that share similar characteristics. The Funds have not adjusted the prices obtained. Investment securities priced using non-binding broker quotes are included in Level 3. As is the case with the primary pricing vendor, third-party brokers do not provide access to their proprietary valuation models, inputs and assumptions. Accordingly, GEAM conducts internal reviews of pricing for all such investment securities periodically to ensure reasonableness of valuations used in the Funds’ financial statements. These reviews are designed to identify prices that appear stale, those that have changed significantly from prior valuations, and other anomalies that may indicate that a price may not be accurate. Based on the information available, GEAM believes that the fair values provided by the brokers are representative of prices that would be received to sell the assets at the measurement date (exit prices).

All portfolio securities of the Money Market Fund and any short-term securities of sufficient credit quality held by any other Fund with remaining maturities of sixty days or less at the time of purchase are valued on the basis of amortized cost which approximates market value and these are included in Level 2.

A Fund’s written or purchased options are valued at the last sales price, or if no sales occurred that day, at the last reported bid price and those are also included in Level 2.

If prices are not readily available for a portfolio security, or if it is believed that a price for a portfolio security does not represent its fair value, the security may be valued using procedures approved by the Funds’ Board of Trustees that are designed to establish its “fair” value. These securities would be classified in Level 3. Those procedures require that the fair value of a security be established by the fair valuation committee. The fair valuation committee follows different protocols for different types of investments and circumstances. The fair value procedures may be used to value any investment of any Fund in the appropriate circumstances.

Foreign securities may be valued with the assistance of an independent fair value pricing service in circumstances where it is believed that they have been or would be materially affected by events occurring after the close of the portfolio security’s primary market and before the close of regular trading on the NYSE. In these circumstances the Fund classifies the investment securities in Level 2. This independent fair value pricing service uses a model to identify affected securities and portfolios taking into consideration various factors and the fair value of such securities may be something other than the last available quotation or other market price.

Portfolio securities may be valued using techniques other than market quotations, under the circumstances described above. The value established for a portfolio security may be different than what would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Funds could sell a portfolio security for the value established for it at any time and it is possible that the Funds would incur a loss because a portfolio security is sold at a discount to its established value.

Other financial investments are derivative instruments that are not reflected in Total Investments, such as futures, forwards, swaps, and written options contracts, which are valued based on fair value as discussed above.

The Funds use closing prices for derivatives included in Level 1, which are traded either on exchanges or liquid over-the counter markets. Derivative assets and liabilities included in Level 2 primarily represent interest rate swaps, cross-currency swaps and foreign currency and commodity forward and option contracts. Derivative assets and liabilities included in Level 3 primarily represent interest rate products that contain embedded optionality or prepayment features.

The inputs or methodology used for valuing securities are not an indication of the risk associated with investing in those securities. Fair value determinations are required for securities whose value is affected by a significant event that will materially affect the value of a domestic or foreign security and which occurs subsequent to the time of the close of the principal market on which such domestic or foreign security trades but prior to the calculation of the Fund’s NAV.
