Investments in Unconsolidated Entities [Abstract] |
Investments in Unconsolidated Entities | Note 8 Investments in Unconsolidated Entities Investments in unconsolidated entities consist of amounts invested in wireless and wireline entities in which TDS holds a noncontrolling interest. On January 1, 2018, TDS adopted Accounting Standards Update 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01) using the modified retrospective approach. Accordingly, prior periods have not been recast to reflect the new accounting principle. Equity securities are measured at fair value with changes in value recognized in Net income. The cumulative effect of applying the provisions of ASU 2016-01 resulted in an increase of $1 million in retained earnings as of January 1, 2018. TDS’ Investments in unconsolidated entities are accounted for using either the equity method or measurement alternative method as shown in the table below. The measurement alternative method was elected for investments without readily determinable fair values formerly accounted for under the cost method. The measurement alternative fair value represents cost minus any impairments plus or minus any observable price changes. TDS did not have an impairment or observable price change related to these investments for the three and six months ended June 30, 2018.
