[1] Applies to liabilities associated with the prior year restructuring and integration programs which relate primarily to employee severance and other retiree benefit enhancements to be paid through 2020 and environmental clean-up costs at our Long Island City, New York location in connection with the closure of our manufacturing operations at the site. These amounts were reclassified out of the restructuring and integration liability and into ongoing accrued liabilities as of December 31, 2016.
