[1] Foreign tax credit carryforwards of $21.0 are expected to be utilized within the remaining allowable 10 year carryfoward period. The foreign tax credit carryforwards were generated in 2013 when we converted a wholly owned French holding company from a disregarded entity to a controlled foreign corporation for U.S. tax purposes, and that conversion caused outstanding intercompany debt to be treated as a deemed dividend taxable in the U.S. Foreign taxes paid on the income that generated the deemed dividend exceeded the U.S. tax cost creating an excess foreign tax credit of $56.7. Additionally, other cash dividends received from our Canadian subsidiary resulted in excess foreign tax credits of $0.9 in 2013.
