The following is a description of the valuation methodologies used for instruments measured at fair value, including the general classification of such instruments: (1) Cash Equivalents: These Level 1 investments consist primarily of highly liquid money market mutual funds traded in active markets. (2) Large Capitalization Equity: The Level 1 investments include a mix of predominately U.S. common stocks and foreign common stocks, which are valued at the closing price reported on the active market in which the individual securities are traded. (3) Small Capitalization Equity: The Level 1 investments include a mix of predominately U.S. common stocks and foreign common stocks, which are valued at the closing price reported on the active market in which the individual securities are traded. (4) Private Equity: These Level 3 investments consist of various collective investment funds, which are managed by a third party, invested in a well-diversified portfolio of equity investments from top performing, high quality firms focused on U.S. and foreign small to mid-markets, venture capitalists, and entrepreneurs with a concentration in areas of innovation. Investment strategies include buyouts, growth capital, buildups, and distressed, as well as early stages of company development mainly in the U.S. The fair value of these funds is based on the fair value of the underlying investments. (5) Fixed Income: The Level 1 investments include U.S. Treasury bonds and notes, which are valued at the closing price reported on the active market in which the individual securities are traded. The Level 2 investments consist principally of U.S. government securities, which are valued daily using institutional bond quote sources and mortgage-backed securities pricing sources and municipal, domestic, and foreign securities, which are valued daily using institutional bond quote sources. (6) Large Capitalization Equity – Domestic: The collective investment is valued at the publicly available NAV of shares held by the Master Trust at year end. The investment objective is to maintain a portfolio of equity securities that approximate the weighted total rate of return within the Standard & Poor’s 500 stock index. There are no restrictions on redemptions. (7) International Equity – Mutual Funds: The mutual funds are valued at the publicly available NAV of shares held by the Master Trust at year end. The investment seeks long term growth of principal and income by investing in medium to large well established companies. There are no restrictions on redemptions. (8) International Equity – Collective Trust: The collective investment funds are valued at the NAV of shares held by the Master Trust at year end. The investment objective of this fund is to generate a long term return through investments in quoted international equities. Redemptions can be made on a monthly basis as of the first business day of each month. (9) Global Equity – Mutual Fund: This investment includes an open-ended mutual fund consisting of a mix of U.S. common stocks and foreign common stocks, which is valued at the publicly available NAV of shares held by the Master Trust at year end. The investment strategy is to obtain long term capital appreciation by focusing on companies generating above average earnings growth and are leading growth businesses in the marketplace. There are no restrictions on redemptions. (10) Real Estate: These investments include ownership in open-ended real estate funds, which manage diversified portfolios of commercial properties within the office, residential, retail, and industrial property sectors. Investment strategies aim to acquire, own, hold, or dispose of investments with the goal of achieving current income and/or capital appreciation. The real estate investments are valued at the NAV of shares held by the Master Trust. Requests to redeem shares are granted on a quarterly basis with either 45 or 90 days advance notice, subject to availability of cash.
