(a) This category represents investments in cash and cash equivalents, which includes: 1.) cash held in the plan used for investments in U.S. Treasury futures which are entered into to minimize the volatility of the estimated settlement funding gap; and 2.) short term money market fund in which the amortized cost approximates fair value. These investments are highly liquid and therefore are classified as level 1 securities. (b) Represents the estimated fair market value of the Company’s ownership in private equity and hedge funds which are probable of being sold for an amount different from the net asset value per share in connection with the expected termination of the pension plan. (c) The collective investment trust contains liability hedging fixed income investments and are valued at the net asset value of the collective investment trust. The net asset value is used as a practical expedient to estimate fair value. The net asset value is based on the fair value of the underlying investments held by the fund less its liabilities. (d) Represents investments in certain commodity funds measured using quoted market prices.
