Due to our history of domestic losses, we have a full valuation allowance for all U.S. net deferred tax assets, including our net operating loss and tax credit carryforwards. As a result, we cannot record any tax benefits for additional U.S. incurred losses and any U.S. income is offset by a reduction in valuation allowance. Irrespective of our income or loss levels, we continue to record U.S. deferred tax expense related to tax-basis goodwill amortization.

The effective rate on our foreign tax expense varies with the mix of income and losses across multiple tax jurisdictions with most statutory tax rates varying from 23% to 33%. The foreign tax expense was higher than the normal effective rate primarily as a result of the current mix of income and losses across jurisdictions
