At December 31, 2024, we have net operating loss carryforwards in Luxembourg of $1.3 billion, the majority of which can be carried forward indefinitely, offset by a full valuation allowance. The remaining portion of the loss carryforwards are composed primarily of losses in various other state and foreign jurisdictions. The majority of these losses can be carried forward indefinitely. At December 31, 2024, there was a valuation allowance of $420.7 million primarily associated with foreign loss carryforwards.
