Income Taxes

The following table summarizes the Company's loss before income taxes and provision for income taxes (in thousands):

	Three Months Ended March 31,
	2022			2021
Loss before income taxes	$	(48,674)		$	(40,521)
Provision for income taxes	447			296
Effective tax rate	(0.9)		%	(0.7)		%

The quarterly income tax provision reflects an estimate of the corresponding year’s annual effective tax rate and includes, when applicable, adjustments for discrete items. The tax provision for the periods presented primarily relates to income taxes of non-U.S. operations as the U.S. operations were in a loss position and the Company maintains a full valuation allowance against its U.S. deferred tax assets.

The Company is subject to income taxes in the United States, China, Germany and India. The Company’s effective tax rate changed from (0.7)% in the three months ended March 31, 2021 to (0.9)% in the three months ended March 31, 2022. This change was primarily due to a combination of permanent tax items, mainly related to the valuation allowance recorded on U.S. deferred tax assets, foreign withholding taxes and state taxes.
