INCOME TAXES
 
The Company's effective income tax rate is based on expected income, statutory rates and tax planning opportunities available in the various jurisdictions in which it operates. For interim financial reporting, the Company estimates the annual income tax rate based on projected taxable income for the full year and records a quarterly income tax provision or benefit in accordance with the anticipated annual rate. The Company refines the estimates of the year's taxable income on a periodic basis as new information becomes available, including actual year-to-date financial results. This continual estimation process often results in a change to the expected effective income tax rate for the year. When this occurs, the Company adjusts the income tax provision during the quarter in which the change in estimate occurs so that the year-to-date provision reflects the expected income tax rate. Significant judgment is required in determining the effective tax rate and in evaluating tax positions.
