[1] Equity securities primarily comprise mutual funds and common/collective trust funds. Investments in mutual funds and common/collective trust funds are valued at the net asset value per share or unit multiplied by the number of shares or units held as of the measurement date. The common/collective trust funds are generally actively managed investment vehicles.

[2] In the U.S. pension plan assets, certain equity and fixed income investments are held in separately managed investment accounts. The underlying investments in these separately managed accounts are primarily publicly traded securities that are directly owned by the U.S. pension plan, and such investments have been valued using the quoted price as of December 31, 2012 and 2011. Accordingly, these investments have been classified as Level 1 as of December 31, 2012 and 2011.

[3] Fixed income investments primarily comprise mutual funds and common/collective trust funds that invest in corporate and government bonds. Investments in mutual funds and common/collective trust funds are valued at the net asset value per share or unit multiplied by the number of shares or units held as of the measurement date. The investments in fixed income securities include both actively managed funds and index funds.

[4] The fair values of insurance contracts are estimated based on the future cash flows to be received under the contracts discounted to the present using a discount rate that approximates the discount rate used to measure the associated pension plan liabilities.

[5] Venture capital and partnerships are valued at net asset value, which is generally calculated using the most recent partnership financial reports.

[6] Real estate investments are generally investments in limited partnerships, real estate investment trusts and similar vehicles that invest in real estate. The values of the investments are generally based on the most recent financial reports of the investment vehicles. The managers of each of the investment vehicles estimate the values of the real estate assets underlying the real estate investments using third-party appraisals and other valuation techniques and analysis.

[7] Cash and cash equivalents include investments in stable value funds. Stable value funds are generally invested in common trust funds and interest-bearing accounts.

[8] Derivatives primarily consist of interest rate and inflation swaps relating to the Company’s international plans. Included in cash and cash equivalents is an amount of $31.4 million that relates to cash collateral posted with third parties for the derivatives that are in a liability position as of December 31, 2012.

[9] Commodity assets primarily consist of exchange traded funds that have publicly quoted prices and are therefore classified as Level 1 investments.
