SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Fund:

Net Asset Value:

The Net Asset Value (“NAV”) of each class of the Fund is determined by dividing the net assets attributable to each class of shares of the Fund by the number of issued and outstanding shares of the class of the Fund on each business day as of 4 p.m. ET.

Security Valuation:

Fixed-income securities for which market quotations are readily available are valued at prices as provided by independent pricing vendors or broker quotes. The Fund receives pricing information from independent pricing vendors approved by the Board of Trustees (the “Board” or the “Board of Trustees”). Securities with a demand feature exercisable within one to seven days are valued at par. The Fund also uses a benchmark pricing system to the extent vendors’ prices for their securities are either inaccurate (such as when the reported prices are different from recent known market transactions) or are not available from another pricing source. For a security priced using this system, the Adviser initially selects a proxy composed of a relevant security (i.e., U.S. Treasury Note) or benchmark (e.g., LIBOR) and a multiplier, divisor or margin that the Adviser believes would together best reflect changes in the market value of the security. The value of the security changes daily based on changes to the market price of the assigned benchmark. The benchmark pricing system is continuously reviewed by the Adviser and implemented according to the pricing policy reviewed by the Board. S&P 500 Index futures contracts are valued at the first sale price after 4 p.m. ET on the Chicago Mercantile Exchange. All other futures contracts are valued at the official settlement price of the exchange where it is traded. Equity securities, including depository receipts, are valued at the last reported sale price or the market’s closing price on the exchange or market on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the average of the bid and asked prices. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange or market determined by the Adviser to be the broadest and most representative market, which may be either a securities exchange or the over-the-counter market. Equity options are valued at the average of the bid and asked prices. Securities and other assets that cannot be valued as described above will be valued at their fair value as determined by the Adviser under guidelines established by and under the general supervision and responsibility of the Board.

Investments in registered open-ended investment companies, including those classified as money market funds, are valued based upon

December 2019 / 17

Intermediate Bond Fund

Schedule of Portfolio Investments

December 31, 2019 (Unaudited)

the reported NAV of such investments.

Fair value methods approved by the Board of Trustees include, but are not limited to, obtaining market quotations from secondary pricing services, broker-dealers, or widely used quotation systems. General factors considered in determining the fair value of securities include fundamental analytical data, the nature and duration of any restrictions on disposition of the securities, and an evaluation of the forces that influenced the market in which the investments are purchased and sold. These securities are either categorized as Level 2 or 3 depending on the relevant inputs used. In the event that the security or asset cannot be valued pursuant to one of the valuation methods established by the Board, the value of the security or asset will be determined in good faith by the Pricing Committee of the Board, generally based upon recommendation provided by the Adviser. When the Fund uses these fair valuation methods applied by the Adviser that use significant unobservable inputs to determine its NAV, securities will be priced by a method that the Board or persons acting at their direction believe accurately reflect fair value and are categorized as Level 3 of the fair value hierarchy. These methods may require subjective determinations about the value of a security. While the Fund’s policy is intended to result in a calculation of its NAV that fairly reflects security values as of the time of pricing, the Fund cannot guarantee that values determined by the Board or persons acting at their direction would accurately reflect the price that the Fund could obtain for a security if it were to dispose of that security as of the time of pricing (for instance, in a forced or distressed sale). The prices used by the Fund may differ from the value that would be realized if the securities were sold.

Fair Value Measurements:

Various inputs are used in determining the fair value of investments, which are as follows:

* Level 1 - unadjusted quoted prices in active markets for identical securities

* Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

* Level 3 - significant unobservable inputs that are not corroborated by observable market data

The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those investments and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to each security.

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition, as well as changes related to liquidity of investments, could cause a security to be reclassified between Level 1, Level 2, or Level 3.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes the level in the fair value hierarchy within which the fair value measurement falls in its entirety is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
