Out-of-period adjustment description | During the three months ended March 31, 2018, TDS recorded out-of-period adjustments attributable to 2016 and 2017 due to errors in the application of accounting guidance applicable to the calculation of Noncontrolling interests with redemption features related to King Street Wireless, Inc.
