[1] Deferred compensation plan assets include mutual funds, common/collective trusts and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees. The fair value of mutual funds and cash equivalents were based on quoted market prices in active markets. The underlying investments in the common/collective trusts primarily include intermediate and long-term debt securities, corporate debt securities, equity securities and fixed income securities. The overall fair value of the common/collective trusts are based on observable inputs.

[2] During the third quarter of 2014, we recognized an impairment charge related to allocated amounts of goodwill, intangible assets, property, plant & equipment and other non-current assets totaling $380.1 million, net of a $12.3 million tax benefit, representing our estimated loss on disposal of the Water Transport business. The impairment charge was determined using significant unobservable inputs ("Level 3" fair value measurements). See Note 3 for additional information about the impairment.
