At December 31, 2014, we have net operating loss carryforwards in Luxembourg of $441.3 million that 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 foreign jurisdictions. The majority of these losses can be carried forward indefinitely. At December 31, 2014, there was a valuation allowance of $256.6 million primarily associated with foreign loss carryforwards and foreign tax credit carryforwards (discussed below).
[2] | For tax return purposes at December 31, 2014, we had: (1) U.S. general business credits of $18.2 million, which begin to expire in 2022; (2) U.S. alternative minimum tax credits of $2.5 million that can be carried forward indefinitely; and (3) U.S. foreign tax credits of $75.4 million, which begin to expire in 2019. At December 31, 2014, there was a valuation allowance of $58.5 million associated with foreign tax credit carryforward.
