These intangible assets are being amortized over

five

years for financial statement purposes due to the short life cycle of technology

on which customer relationships depend and over

15

years on a straight-line basis for tax purposes. The intangible amortization expenses were

$1,062,000

for the

three

-month period ended

December 31, 2017,

as compared with

$1,224,000

in the prior year period, primarily because the intangibles of

one

of the

two

acquisitions in fiscal

2013

were fully amortized during this quarter.
