INCOME TAX
(5) INCOME TAXES
     Our estimated annual effective tax rate, adjusted for unusual tax items, is applied to interim periods’ pretax income (loss). Except for a portion of the current year’s foreign earnings, which have been remitted to the U.S., we consider earnings of our foreign subsidiaries to be permanently reinvested, and as such, we have not provided for any U.S. federal or state income taxes on these permanently reinvested earnings.
