Numbers may not foot due to rounding. 1"All Other" represents TDS' non-reportable other business activities that do not meet the quantitative thresholds for being a reportable segment. 2 The significant segment expense categories and amounts align with the segment-level information that is regularly provided to the chief operating decision maker. Intersegment expenses are included within the amounts shown. 3 This item is not included in the evaluation of operating performance of the Wireless and Towers segments, and therefore is reported as "UScellular". 4 Assets are not provided at the individual segment level for Wireless and Towers, and therefore is reported for "UScellular". The UScellular segments operate under a common capital structure, and management has historically considered its assets collectively as part of a combined wireless network.
