[1] The amount for 2014 mainly consists of charges recorded in the second quarter for certain multi-product facility project costs that we do not expect to recover in future periods, net of other credits recorded in the fourth quarter.

[2] See Note 21, “Restructuring and Other.”

[3] In 2014, we initiated action to reduce high cost supply capacity of certain aluminum alkyl products, primarily through the termination of a third party manufacturing contract. Based on the contract termination, we estimated costs of approximately $14.0 million ($9.3 million after income taxes) in the first quarter and $6.5 million ($4.3 million after income taxes) in the fourth quarter for contract termination and volume commitments. Additionally, in the first quarter of 2014 we recorded an impairment charge of $3.0 million ($1.9 million after income taxes) for certain capital project costs also related to aluminum alkyls capacity which we do not expect to recover.

[4] In the third quarter of 2015, a gain of $6.8 million ($5.4 million after income taxes) was recognized upon the sale of land in Avonmouth, U.K., which was utilized by the phosphorus flame retardants business we exited in 2012. In 2012, charges in connection with our exit of the phosphorus flame retardants business were recorded in Restructuring and other, net, on our consolidated statements of income.
