Equity [Abstract]
SoftBank Equity Transaction	Note 14 - SoftBank Equity Transaction On June 22, 2020, we entered into a Master Framework Agreement (the “Master Framework Agreement”), by and among the Company, SoftBank, SoftBank Group Capital Ltd, a wholly-owned subsidiary of SoftBank (“SBGC”), Delaware Project 4 L.L.C., a wholly-owned subsidiary of SoftBank, Delaware Project 6 L.L.C., a wholly-owned subsidiary of SoftBank, Claure Mobile LLC (“CM LLC”), DT, and T-Mobile Agent LLC, a wholly-owned subsidiary of the Company. The Master Framework Agreement and related transactions were entered into to facilitate SoftBank’s monetization of a portion of our common stock held by SoftBank (the “SoftBank Monetization”). In connection with the Master Framework Agreement, DT waived the restriction on the transfer under its Proxy, Lock-Up and ROFR Agreement, dated April 1, 2020, with SoftBank (the “SoftBank Proxy Agreement”) with respect to approximately 198 million shares of our common stock held by SoftBank (the “Released Shares”). Upon the close of the Public Equity Offering (as defined below), we received a payment from SoftBank for $300 million for our role in facilitating the SoftBank Monetization. The payment received from SoftBank, net of tax, of $226 million was recorded as Additional paid-in capital in our Condensed Consolidated Balance Sheets and is presented as a reduction of Repurchases of common stock within Net cash provided by (used in) financing activities within our Condensed Consolidated Statements of Cash Flows. Under the terms of the Master Framework Agreement and the agreements contemplated thereby, SBGC sold the Released Shares to us, and we participated in the following transactions: Public Equity Offering: On June 26, 2020, we completed a registered public offering of approximately 154.1 million shares of our common stock (the “Public Equity Offering”) at a price of $103.00 per share. The net proceeds of the Public Equity Offering were used to repurchase an equal number of issued and outstanding shares of our common stock from SBGC, pursuant to a Share Repurchase Agreement, dated as of June 22, 2020 (the “Share Repurchase Agreement”), between us and SBGC. Mandatory Exchangeable Offering: Concurrent with the Public Equity Offering, we sold approximately 19.4 million shares of our common stock to a third-party trust. The net proceeds from the sale of shares to the trust were used to repurchase an equal number of issued and outstanding shares of our common stock from SBGC. The trust issued mandatory exchangeable trust securities, which entitle holders to receive quarterly distributions from the trust and a final mandatory exchange price to be settled on June 1, 2023 (“Mandatory Exchangeable Offering”). The trust was required to use a portion of the net proceeds from the Mandatory Exchangeable Offering to purchase U.S. Treasury securities, to fund quarterly distributions on the mandatory exchangeable trust securities, and the holders of the mandatory exchangeable trust securities will be entitled to a final mandatory exchange amount on June 1, 2023 that will depend on the daily volume-weighted average price of shares of our common stock. The sale of shares through the Public Equity Offering and to the trust occurred simultaneously with the purchase of shares from SBGC. These simultaneous transactions did not result in a net change to our treasury shares or shares of common stock outstanding. As these transactions occurred with separate counterparties, the exchange of shares and cash are presented on a gross basis in our Condensed Consolidated Statement of Equity and Condensed Consolidated Statements of Cash Flows, respectively. The shares sold are presented in Shares issued in secondary offering and the shares purchased from SBGC are presented in Shares repurchased from SoftBank within our Condensed Consolidated Statement of Equity. The cash received from the sale of shares is presented in Issuance of common stock and the cash paid to purchase shares from SoftBank are presented in Repurchases of common stock within Net cash provided by (used in) financing activities within our Condensed Consolidated Statements of Cash Flows. The Company is not affiliated with the trust, will not retain any proceeds from the offering of the trust securities, and will have no ongoing interest, economic or otherwise, in the trust securities. Rights Offering: The Master Framework Agreement provides for the issuance of registered, transferable subscription rights (the “Rights Offering”) resulting in the sale of 19,750,000 shares of our common stock to our stockholders (other than SoftBank, DT and Marcelo Claure and their respective affiliates, who agreed to waive their ability to exercise or transfer such rights). The subscription rights provided the stockholders the option to purchase one share of common stock for every 20 shares of common stock owned, at the same price per share as the common stock sold in the Public Equity Offering of $103.00 per share. The Rights Offering exercise period expired on July 27, 2020. On August 3, 2020, the Rights Offering closed, resulting in the sale of 19,750,000 shares of our common stock. The net proceeds from the Rights Offering were used to purchase an equal number of shares from SBGC pursuant to the Share Repurchase Agreement. Marcelo Claure: The Master Framework Agreement provided for the purchase of 5.0 million shares of our common stock by Marcelo Claure, a member of our board of directors, from us at the same price per share as the common stock sold in the Public Equity Offering of $103.00 per share. Following receipt of the necessary regulatory approvals on July 16, 2020, the sale of shares to Marcelo Claure occurred simultaneously with our purchase of an equivalent number of shares from SBGC at the same price per share pursuant to the Share Repurchase Agreement. Ownership Following the SoftBank Monetization: Immediately following the transactions above, DT and SoftBank held, directly or indirectly, approximately 43.4%, and 8.6%, respectively, of the outstanding T-Mobile common stock, with the remaining approximately 48.0% of the outstanding T-Mobile common stock held by other stockholders. The SoftBank Proxy Agreement remains in effect with respect to the remaining shares of our common stock held by SoftBank. In addition, on June 22, 2020, DT, CM LLC, and Marcelo Claure entered into a Proxy, Lock-Up and ROFR Agreement (the “Claure Proxy Agreement,” together with the SoftBank Proxy Agreement, the “Proxy Agreements”), pursuant to which any shares of our common stock acquired after June 22, 2020 by Mr. Claure or CM LLC, an entity controlled by Mr. Claure, other than shares acquired as a result of Mr. Claure’s role as a director or officer of the Company, will be voted in the manner as directed by DT. Accordingly, as a result of the Proxy Agreements, DT has voting control as of August 3, 2020 over approximately 52.4% of the outstanding T-Mobile common stock. In addition, as provided for in the Master Framework Agreement, DT also holds certain call options over approximately 101.5 million shares of our common stock held by SBGC. DT Call Option: In exchange for DT consenting to the transfer of the Released Shares and as provided for in the Master Framework Agreement, DT received direct and indirect call options over up to approximately 101.5 million shares of our common stock held by SBGC. The arrangement provides DT with a fixed-price call option to purchase up to approximately 44.9 million shares at a price of $101.46 per share indirectly from SBGC through a back-to-back arrangement where (i) DT can purchase such shares from us (the “DT Fixed-Price Call Option”) and (ii) we will fulfill our obligations under the DT Fixed-Price Call Option by simultaneously purchasing the same number of shares on the same economic terms from SBGC (the “T-Mobile Fixed-Price Call Option”). In addition, DT has a floating-price call option to purchase up to approximately 56.6 million shares from SBGC directly (the “DT Floating Option”). The call options expire on June 22, 2024 (the “Expiration Time”). The back-to-back arrangement can be initiated by DT at any time prior to the Expiration Time. The DT Floating Option cannot be exercised until the earlier of (i) 30 days prior to the Expiration Time and (ii) the later of (x) the date the DT Fixed-Price Call Option and the T-Mobile Fixed-Price Call Option are exercised in full and (y) October 2, 2020. Our obligations to DT under the DT Fixed-Price Call Option are secured solely by our rights under the T-Mobile Fixed-Price Call Option and DT has no recourse against us other than enforcement of this security arrangement. The DT Fixed-Price Call Option and the T-Mobile Fixed-Price Call Option represent free-standing derivatives and are recorded at fair value and marked-to-market each period. The fair value of each call option was estimated at $875 million as of June 30, 2020 using the income approach. The fair value measurements are based on significant inputs not observable in the market and, therefore, represent a Level 3 measurement as defined in ASC 820. The key assumptions in applying the income approach include estimated share-price volatility, which was based on historical market trends and expected future performance of T-Mobile, as well as the assessment of counterparty credit risk. The asset associated with the T-Mobile Fixed-Price Call Option is recorded within Other current assets in the Condensed Consolidated Balance Sheets, and the liability associated with the DT Fixed-Price Call Option is recorded within Other current liabilities in the Condensed Consolidated Balance Sheets. As the mark-to-market valuations of the T-Mobile Fixed-Price Call Option and the DT Fixed-Price Call Option move in equal and offsetting directions, there is no net impact on our Condensed Consolidated Income Statement.

On June 22, 2020, we entered into a Master Framework Agreement (the “Master Framework Agreement”), by and among the Company, SoftBank, SoftBank Group Capital Ltd, a wholly-owned subsidiary of SoftBank (“SBGC”), Delaware Project 4 L.L.C., a wholly-owned subsidiary of SoftBank, Delaware Project 6 L.L.C., a wholly-owned subsidiary of SoftBank, Claure Mobile LLC (“CM LLC”), DT, and T-Mobile Agent LLC, a wholly-owned subsidiary of the Company.
