The Company's estimated annual effective income tax rate assumes that a significant portion of its net operating loss carryforwards will be utilized in 2023 and the release of the valuation allowance associated with the asset. This will be more than offset by the capitalization of research and development expenses under current U.S. tax rules for which a valuation allowance will be provided. The net of these items is included in the valuation allowance line in the table above. The Company's reported income tax rate in the prior year differed from the U.S. federal statutory tax rate primarily as a result of recording additional valuation allowances and an interim adjustment resulting from pretax losses for which no tax benefit was recognized.
