Our provision for income taxes for each of the three-month and six-month periods ended June 30, 2014 and 2013 were calculated based on the estimated annual effective income tax rate for the full 2014 and 2013 fiscal years.  The actual effective income tax rate for the full 2014 fiscal year may be materially different as a result of differences between estimated versus actual results and the geographic tax jurisdictions in which the results are earned.
