The difference between the U.S. federal statutory tax rate of 35% and the Company’s effective tax rate in all periods is primarily due to income earned in lower tax rate jurisdictions, for which no U.S. income tax has been provided, as the Company intends to permanently reinvest these earnings outside of the U.S.

The Company’s total gross unrecognized tax benefits as of July 2, 2016, determined in accordance with FASB authoritative guidance for measuring uncertain tax positions, increased by $861 thousand in the first quarter of fiscal 2017 to $34.9 million.

It is reasonably possible that changes to our unrecognized tax benefits could be significant in the next twelve months due to tax audit settlements and lapses of statutes of limitation.
