We believe that these technologies will further enhance our existing capabilities, as well as future initiatives. We completed the acquisition for a gross purchase price of </font><font style="font-family:Arial;font-size:10pt;">$19.28 million</font><font style="font-family:Arial;font-size:10pt;">. Pursuant to the purchase agreement, </font><font style="font-family:Arial;font-size:10pt;">$3.0 million</font><font style="font-family:Arial;font-size:10pt;"> of the total purchase consideration is being held by us for a period of eighteen months following the closing of the acquisition. This holdback amount has been recorded as a non-current liability on our Consolidated Balance Sheet as of September 28, 2018. We have completed a preliminary purchase price allocation and the balance sheet reflects the preliminary fair value estimates of the intangible assets and goodwill acquired. These estimates are subject to change within the measurement period which will not exceed one year from the acquisition date.</font></div></div>
