An enterprise is required, at the end of each interim reporting period, to make its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period. Our effective tax rate for the three and six months ended June 30, 2013 was 25.5% and 25.8%, respectively. Our effective tax rate for the three and six months ended June 30, 2012 was 30.7% and 31.5%, respectively. For the three and six months ended June 30, 2013, the effective tax rate is less than the federal statutory rate primarily due to earnings in jurisdictions outside the United States, where our effective tax rate is lower, which was partially offset by state income taxes, non-deductible stock compensation and accruals on uncertain tax positions. The decrease in the effective tax rate for 2013 compared to the 2012 rate was primarily due to an increase in earnings in jurisdictions outside the United States as well as an internal restructuring that occurred during the fourth quarter of 2012.

These audits include questioning the timing and the amount of income and deductions and the allocation of income among various tax jurisdictions.

NOTE 10: INCOME TAXES

Each interim period is considered an integral part of the annual period and, accordingly, we measure our tax expense using an estimated annual effective tax rate. An enterprise is required, at the end of each interim reporting period, to make its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period.

Our effective tax rate for the three and six months ended June 30, 2013 was 25.5% and 25.8%, respectively. Our effective tax rate for the three and six months ended June 30, 2012 was 30.7% and 31.5%, respectively.
