Valuation Technique on Contingent Consideration			The Company holds an 80% interest in iKnowtion. In the event iKnowtion meets certain EBITDA targets for calendar year 2015, the purchase and sale agreement requires TeleTech to purchase the remaining 20% interest in iKnowtion in 2016 for an amount equal to a multiple of iKnowtion’s 2015 EBITDA as defined in the purchase and sale agreement.	The fair value of the contingent payments was measured based on significant inputs not observable in the market (Level 3 inputs). Key assumptions include a discount rate of 5.3% and expected future value of payments of $2.6 million. The $2.6 million of expected future payments was calculated using a bell curve probability weighted EBITDA assessment with the highest probability associated with WebMetro achieving the targeted EBITDA for each earn-out year.
