(1) Restricted marketable investment securities and restricted cash and cash equivalents are included in “Restricted cash, cash equivalents and marketable investment securities” on our Consolidated Balance Sheets.

Marketable Investment Securities

Our marketable investment securities portfolio may consist of debt and equity instruments. All equity securities are carried at fair value, with changes in fair value recognized in “Other, net” within “Other Income (Expense)” on our Consolidated Statements of Operations and Comprehensive Income (Loss). All debt securities are classified as available-for-sale and are recorded at fair value. We report the temporary unrealized gains and losses related to changes in market conditions of marketable debt securities as a separate component of “Accumulated other comprehensive income (loss)” within “Stockholders’ Equity (Deficit),” net of related deferred income tax on our Consolidated Balance Sheets. The corresponding changes in the fair value of marketable debt securities, which are determined to be company specific credit losses are recorded in “Other, net” within “Other Income (Expense)” on our Consolidated Statements of Operations and Comprehensive Income (Loss). See Note 2 for further information.

Current Marketable Investment Securities - Strategic

Our current strategic marketable investment securities portfolio includes and may include strategic and financial debt and/or equity investments in private and public companies that are highly speculative and have experienced and continue to experience volatility. As of December 31, 2022, this portfolio consisted of securities of a small number of issuers, and as a result the value of that portfolio depends, among other things, on the performance of those issuers. The fair value of certain of the debt and equity securities in this portfolio can be adversely impacted by, among other things, the issuers’ respective performance and ability to obtain any necessary additional financing on acceptable terms, or at all.

Current Marketable Investment Securities - Other

Our current other marketable investment securities portfolio includes investments in various debt instruments including, among others, commercial paper, corporate securities and United States treasury and/or agency securities.

Commercial paper consists mainly of unsecured short-term, promissory notes issued primarily by corporations with maturities ranging up to 365 days. Corporate securities consist of debt instruments issued by corporations with various maturities normally less than 18 months. U.S. Treasury and agency securities consist of debt instruments issued by the federal government and other government agencies.

Restricted Cash, Cash Equivalents and Marketable Investment Securities

As of December 31, 2022 and 2021, our restricted marketable investment securities, together with our restricted cash and cash equivalents, included amounts required as collateral for our letters of credit and trusts.

In addition, as of December 31, 2021, our restricted marketable investment securities, together with our restricted cash and cash equivalents include the proceeds from the issuance of our 5 1/4% Senior Secured Notes due 2026 and our 5 3/4% Senior Secured Notes due 2028, which included certain restrictions which varied in nature depending on the ultimate use of proceeds. The cash proceeds were paid to the FCC in connection with our wholly-owned subsidiary Weminuche L.L.C.’s (“Weminuche”) winning bids in the FCC’s auction for the Flexible-Use Service Licenses in the 3.45–3.55 GHz band (“Auction 110”). See Note 10 for further information.

Other Investment Securities

We have strategic investments in certain debt and/or equity securities that are included in noncurrent “Other investment securities” on our Consolidated Balance Sheets. Our debt securities are classified as available-for-sale and our equity securities are accounted for using the equity method of accounting or recorded at fair value. Certain of our equity method investments are detailed below.

NagraStar L.L.C. We own a 50% interest in NagraStar L.L.C. (“NagraStar”), a joint venture that is our primary provider of encryption and related security systems intended to assure that only authorized customers have access to our programming.

Invidi Technologies Corporation. In November 2016, we, AT&T Inc., and Cavendish Square Holding B.V., an affiliate of WPP plc, entered into a series of agreements to acquire Invidi Technologies Corporation (“Invidi”), an entity that provides proprietary software for the addressable advertising market.

TerreStar Solutions, Inc.  In March 2019, we closed a transaction with TerreStar Solutions, Inc. (“TSI”) to acquire additional equity securities of TSI, an entity that holds certain 2 GHz wireless spectrum licenses in Canada, in exchange for certain Canadian assets, including, among other things, a portion of the satellite capacity on our T1 satellite, which we had acquired from TerreStar Networks, Inc. in 2012. 

Our ability to realize value from our strategic investments in securities that are not publicly traded depends on, among other things, the success of the issuers’ businesses and their ability to obtain sufficient capital, on acceptable terms or at all, and to execute their business plans. Because private markets are not as liquid as public markets, there is also increased risk that we will not be able to sell these investments, or that when we desire to sell them we will not be able to obtain fair value for them.

As of December 31, 2022, restricted and non-restricted marketable investment securities included debt securities of $875 million with contractual maturities within one year and $2 million with contractual maturities extending longer than one year through and including five years. Actual maturities may differ from contractual maturities as a result of our ability to sell these securities prior to maturity.

Derivative Instruments

We have the option to purchase certain of T-Mobile’s 800 MHz spectrum licenses from T-Mobile at a fixed price in the future.  This instrument meets the definition of a derivative and was valued based upon, among other things, our estimate of the underlying asset price, the expected term, volatility, the risk free rate of return and the probability of us exercising the option. The instrument acquisition date fair value was $713 million. The derivative is remeasured quarterly. As of December 31, 2022 and 2021, the derivative’s fair value was $1.693 billion and $678 million, respectively, and is included in “Other noncurrent assets, net” on our Consolidated Balance Sheets. The change in the derivative’s fair value was primarily driven by Level 3 current market data indicative of pricing of similar assets and an increase in our probability of exercising the option, which resulted in an increase in our estimate of our derivative’s underlying asset value. Substantially all of the change in the derivative’s fair value occurred in the fourth quarter of 2022. All changes in the derivative’s fair value are recorded in “Other, net” on our Consolidated Statements of Operations and Comprehensive Income (Loss) until the option is either exercised or expires. See the table below. If we elect to exercise the option and purchase these licenses, we will record the licenses at fair value at that date in “FCC authorizations” on our Consolidated Balance Sheets. If we elect to not exercise the option or it expires, we will expense the derivative’s fair value at that date on our Consolidated Statements of Operations and Comprehensive Income (Loss) and are potentially subject to pay T-Mobile a fee of approximately $72 million per the Spectrum Purchase Agreement under certain circumstances. See Note 15 for more information.

We account for our option to purchase certain T-Mobile’s 800 MHz spectrum licenses under the Spectrum Purchase Agreement as a Level 3 derivative.
