The estimated annual amortization expense for each of the five succeeding fiscal years are as follows (U.S. dollars in thousands):

Year Ending December 31,

2017	$	8,460
2018		8,650
2019		8,480

All of the Company's goodwill is based in the U.S. Goodwill and indefinite life intangible assets are not amortized, rather they are subject to annual impairment tests. Annual impairment tests were completed resulting in no impairment charges for any of the periods shown. Finite life intangibles are amortized over their useful lives unless circumstances occur that cause the Company to revise such lives or review such assets for impairment.
