The Company determined the fair values of the trade names using a relief-from-royalty methodology. The Company believes that the useful life of the trade name for GPS represents the number of years that such intangibles are expected to contribute to future cash flows. The useful lives for the trade names for Roberts and SMC are considered to be indefinite. In order to value the process certifications of Roberts, the Company applied a reproduction cost new method that required the estimation of the costs to replace the assets with certifications that would have the same functionality or utility as the acquired assets. Other intangible assets include primarily the fair values estimated for acquired contract backlogs, other customer relationships and non-compete agreements. The tables below present the activity for the years ended January 31, 2016 and 2015 related to intangible assets, excluding goodwill, that were acquired in connection with business combinations.
