Note 6. Income Taxes

The effective tax rate for the three and nine months ended June 30, 2020 was 9.6% and 20.9%, respectively. The effective tax rate for the three and nine months ended June 30, 2020 was lower than the statutory federal rate primarily due to (i) the annual domestic federal return-to-provision adjustments, (ii) adjustments to certain uncertain tax positions and (iii) research and development tax credits, partially offset by the (iv) inclusion of state taxes, (v) income derived from certain foreign jurisdictions subject to higher tax rates, (vi) the exclusion of tax

benefits related to losses recorded by certain foreign operations, and (vii) tax expense related to stock based compensation.

The effective tax rate for the three and nine months ended June 30, 2019 was 23.4% and 25.2%, respectively. The effective tax rate for the three months ended June 30, 2019 was higher than the statutory federal rate primarily due to (i) the inclusion of state taxes, (ii) income derived from certain foreign jurisdictions subject to higher tax rates and (iii) the exclusion of tax benefits related to losses recorded by certain foreign operations, partially offset by (iv) the inclusion of tax benefits related to state tax law changes and (v) research and development tax credits. The effective tax rate for the nine months ended June 30, 2019 was higher than the statutory federal rate primarily due to (i) the inclusion of state taxes, (ii) income derived from certain foreign jurisdictions subject to higher tax rates, (iii) the exclusion of tax benefits related to losses recorded by certain foreign operations, (iv) the limitation of certain transaction costs and (v) the increase of deferred tax liabilities in certain state jurisdictions, partially offset by (vi) the inclusion of tax benefits related to share-based compensation and state tax law changes, (vii) research and development tax credits and (viii) an adjustment of the valuation allowance against net operating losses of foreign subsidiaries.
