INCOME TAXES	11.INCOME TAXES The income tax provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the estimate of the annual effective tax rate is updated, and if the estimated effective tax rate changes, a cumulative adjustment is made. There is a potential for volatility of the effective tax rate due to several factors, including changes in the mix of the pre-tax income and the jurisdictions to which it relates, changes in tax laws and foreign tax holidays, settlements with taxing authorities and foreign currency fluctuations. The effective income tax rate as a percentage of income before income taxes was 32.1% and 34.6% in the first quarter 2015 and 2014, respectively. The effective tax rate for the first quarter of 2015 and 2014 is lower than the statutory rate primarily due to differences in state and foreign tax rates and the mix of foreign and domestic sales. The effective tax rate for 2015 is lower than 2014 primarily due to state taxes.
