NOTE e—TAXES ON Income

The effective tax rate used in computing the provision for income taxes is based on projected fiscal year income before taxes, including estimated income by tax jurisdiction. Tax provision for the three months ended March 31, 2016 and 2015 does not include tax benefits associated with equity-based compensation expenses.

The total amount of net unrecognized tax benefits was $1,906 and $1,711 at March 31, 2016 and December 31, 2015, respectively. The Company accrues interest and penalties, relating to unrecognized tax benefits, in its provision for income taxes. At March 31, 2016 and December 31, 2015, the Company had accrued interest and penalties relating to unrecognized tax benefits of $199 and $180, respectively.

The Company intends to permanently reinvest earnings of its foreign operations and its current operating plans do not demonstrate a need to repatriate foreign earnings to fund the Company’s U.S. operations. However, if these funds were needed for the Company’s operations in the United States, the Company would be required to accrue and pay U.S. taxes as well as taxes in other countries to repatriate these funds. The determination of the amount of additional taxes related to the repatriation of these earnings is not practicable, as it may vary based on various factors such as the location of the cash and the effect of regulation in the various jurisdictions from which the cash would be repatriated.
