Less: accumulated depreciation		(94,717		)	(78,826		)
		$	50,980		$	51,643

The $663 decrease in property and equipment was primarily due to the full year impact of accumulated depreciation associated with the build-out of the Company's new corporate headquarters, integration activities associated with recently acquired businesses, partially offset by current year additions, including the property and equipment associated with the acquisition of Themis. During fiscal 2018 and 2017, the Company retired $611 and $14,310, respectively, of computer equipment and software, furniture, and fixtures, leasehold improvements, and machinery and equipment that were no longer in use by the Company. 

Depreciation expense related to property and equipment for the fiscal years ended June 30, 2018, 2017 and 2016 was $16,273, $12,589 and $6,900, respectively.
