Income Taxes	Income Taxes: The effective income tax rate for the three-month period ended March 31, 2016 was 12.4%, compared to 27.8% for the three-month period ended March 31, 2015. The Company’s effective income tax rate fluctuates based on, among other factors, its level and location of income. The difference between the U.S. federal statutory income tax rate and our effective income tax rate for the 2016 and 2015 periods is primarily due to the impact of earnings from outside the U.S. The decrease in the effective tax rate for the three-month period ended March 31, 2016 compared to the same period in 2015 is primarily driven by income from the sales of businesses and associated tax expense of $6.3 million. Our effective income tax rate for the three-month period ended March 31, 2015 was affected by $3.2 million related mainly to U.S. tax provision to return adjustments, and the OPEB plan termination gain described in Note 13, “Pension Plans and Other Postretirement Benefits.”
