Income Tax Holidays Description		The Company has been granted “Tax Holidays” as an incentive to attract foreign investment by the governments of the Philippines and Costa Rica. Generally, a Tax Holiday is an agreement between the Company and a foreign government under which the Company receives certain tax benefits in that country, such as exemption from taxation on profits derived from export-related activities. In the Philippines, the Company has been granted multiple agreements under local laws which result in an overall reduced tax rate. These incentives have varying benefit year over year and expire at various times beginning in 2031.
