(1) This class represents investments in actively managed common trust funds that invest primarily in equity securities, which may include common stocks, options and futures. The funds are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. The investments are valued based on market values and yields currently available for comparable securities of issuers with similar credit ratings. The Level of the fund(s) (Level 1, 2 or 3) is determined based on the classification of the significant holdings within the fund. (2) This class represents investments in actively managed common trust funds that invest in a variety of fixed income investments, which may include corporate bonds, both U.S. and non-U.S. municipal securities, interest rate swaps, options and futures. The funds are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. The investments are valued based on yields currently available for comparable securities of issuers with similar credit ratings. The Level of the fund(s) (Level 1, 2 or 3) is determined based on the classification of the significant holdings within the fund. (3) This class represents investments in actively managed common trust funds with investments in both equity and debt securities. The investments may include common stock, corporate bonds, U.S. and non-U.S. municipal securities, interest rate swaps, options and futures. The funds are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. The investments are valued based on market values and yields currently available for comparable securities of issuers with similar credit ratings. The Level of the fund(s) (Level 1, 2 or 3) is determined based on the classification of the significant holdings within the fund. (4) Short term investments are valued at $1.00/unit, which approximates fair value. Amounts are generally invested in actively managed common trust funds or interest bearing accounts. (5) This category represents investments in insurance contracts, private equity and publicly traded real estate investment trusts. The insurance contracts and private equity investments are valued using unobservable inputs from the fund manager, primarily based on discounted cash flow models.

(1) An increase in the number of inactive participants in one of our domestic pension plans resulted in almost all of the plan participants being inactive. Accordingly, in 2011 we began amortizing the unrecognized gains/losses over the average remaining life expectancy of the inactive participants as opposed to the average remaining service period of the active participants. This change resulted in a reduction to pension expense of approximately $20.0 for the year ended December 31, 2011.
