 The NAV is used as a practical expedient to estimate fair value. Unit values are determined by the issuer or third party administrator by dividing the fair values of the total net assets at year-end by the outstanding units. There were no unfunded commitments, no restrictions on redemption frequency, and no advance notice periods required for redemption for these investments.

• Synthetic GICs are stated at contract value. There are no reserves against contract value for credit risk of the contract issuer. The fixed-income securities underlying the contracts were valued based on the pricing methodology stated below for fixed-income securities.

• Fixed-income securities, including government and agency securities, corporate bonds, and mortgage and asset-backed securities, are primarily valued using a market approach using matrix pricing, which considers a security’s relationship to other securities for which quoted prices in an active market may be available, or alternatively based on an income approach, which uses valuation techniques to convert future cash flows to a single present value amount. The valuation approach is designed to maximize the use of observable inputs, such as observable trade prices, multiple broker-dealer quotations, related yield curves, and other assumptions about the security (prepayment projections, cash flows, other security characteristics, etc.) and minimize unobservable inputs. The securities are valued as of the last trading day of the year. Fixed-income instruments that have a delayed future settlement such as to-be-announced securities (“TBAs”) are valued similarly to fixed-income securities in active markets. TBAs are included in the underlying assets associated with the synthetic GICs, other receivables, and other liabilities on the Master Trust’s statements of net assets.

• Mutual funds, which are registered investment companies, are valued at the daily closing price as reported by the fund. Funds held by the Master Trust are open-ended funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily NAV and to transact at that price.

• Short-term investments include certificates of deposits, commercial paper, treasury bills, and discounted notes with original maturities greater than three months, but less than one year. These investments are primarily valued using a market approach in the same manner as fixed-income securities referenced above.

• Other investments include physical commodities and over-the-counter (“OTC”) derivatives, such as options and swap contracts. Physical commodities are valued on a market approach using the front month futures contract for the specific commodity. The derivatives are valued using a market approach and are based upon the expected amount that the Master Trust would receive or pay to exit the derivative at the
