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

$2,559,000

for the

nine

-month period ended

June 30, 2018,

as compared with

$3,671,000

in the prior year period, primarily because the intangible assets of

one

of the

two

acquisitions in fiscal

2013

were fully amortized during the

first

quarter of fiscal

2018.
