Mandatorily Redeemable Noncontrolling Interest [Abstract]
Description of mandatorily redeemable noncontrolling interest	The Company held an 80% interest in iKnowtion until January 1, 2016 when the additional 20% was purchased. In the event iKnowtion met certain EBITDA targets for calendar year 2015, the purchase and sale agreement required 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. These terms represented a contingent redemption feature which the Company determined was probable of being achieved.Based on final EBITDA for 2015, the payment for the remaining 20% was completed in April 2016 for the value shown in the table below in accordance with the purchase and sale agreement.The Company has recorded the mandatorily redeemable noncontrolling interest at the redemption value based on the corresponding EBITDA multiples as prescribed in the purchase and sale agreement at the end of each reporting period. At the end of each reporting period the changes in the redemption value are recorded in retained earnings. Since the EBITDA multiples as defined in the purchase and sale agreement are below the current market multiple, the Company has determined that there is no preferential treatment to the noncontrolling interest shareholders resulting in no impact to earnings per share.
