Management believes that sufficient income will be earned in the future to realize the remaining net deferred income tax assets. Tax loss carry-forwards of $67,523 have remaining carry- forward periods ranging from two years to unlimited. The Company has tax credit carry-forwards of $4,097, with remaining carry-forward periods ranging from one to 10 years. 

The Company has not recognized deferred income taxes on $149,937 of undistributed earnings of its international subsidiaries, since such earnings are considered to be reinvested indefinitely. If the earnings were distributed in the form of dividends, the Company would be subject, in certain cases, to both U.S. income taxes and foreign withholding taxes. Determination of the amount of this unrecognized deferred income tax liability is not practicable.
