The variance in the effective tax rate is primarily due to uncertain income tax position benefits which decreased the effective tax rate by 1% in the prior year and R&D and state research and development credits which decreased the prior year effective tax rate by 1%, more than offset by increased taxable income in lower tax rate jurisdictions in the current year.
