Goodwill generated from this acquisition is primarily attributable to expected synergies from combining operations and expanding market potential, and is assigned to the Americas Staffing reporting unit. The amount of goodwill expected to be deductible for tax purposes is approximately $18.8 million as of the first quarter-end 2018. An indemnification asset of $2.8 million was recognized as of the acquisition date related to pre-acquisition tax liabilities. As of the first quarter end 2018, the indemnification asset is $0.1 million with the change driven by cash received from the seller to pay pre-acquisition tax liabilities.
