(1) We consistently report the effects of the state valuation allowance on the state income tax expense line-item within our effective tax rate. In 2024, we released $1.2 billion of our valuation allowance on our U.S. state deferred tax assets, with the exception of our California R&D credits.
(2) In the fourth quarter of 2022, we transferred certain intangible assets among our wholly-owned subsidiaries to align our structure to our evolving operations. The transfer resulted in a net reduction in deferred tax assets of $1.7 billion; however, there was no financial statement expense recognized since the deferred tax asset was offset by a full valuation allowance.
(3) In 2024, we released $5.2 billion of our valuation allowance on our U.S. federal deferred tax assets. This is included on the change in valuation allowance line-item.

(1) In 2024, new information became available that required a remeasurement of a prior year transfer pricing tax position resulting in an overall reduction in our net deferred tax assets of $1.2 billion, which is fully offset by a change in the valuation allowance. This is reflected in the increases to prior year uncertain tax positions above.
