The weighted average amortization period in the above table excludes fully amortized intangible assets.

Amortization expense for the three months ended April 30, 2016 and 2015 was $4,776,000 and $1,561,000, respectively. Amortization expense for the nine months ended April 30, 2016 and 2015 was $7,348,000 and $4,682,000, respectively.

As of April 30, 2016, as further discussed in Note (2) - "Acquisition," intangible assets include newly acquired intangibles resulting from the TCS acquisition. The amount of the purchase price for TCS allocated to intangible assets with finite lives was based upon a preliminary valuation and estimates and assumptions that are subject to change within the measurement period (not to exceed one year from the date of acquisition).

The estimated amortization expense consists of the following for the fiscal years ending July 31:



2016	$	13,360,000
2017	22,786,000
2018	21,150,000
2019	17,230,000
2020	17,230,000
