Marketable Investment Securities

Our marketable investment securities portfolio consists of various debt and equity instruments, all of which are classified as available-for-sale.

Current Marketable Investment Securities

Our current marketable investment securities portfolio includes investments in equity securities and various debt instruments including, among others, commercial paper, corporate securities and U.S. 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 March 31, 2016 and December 31, 2015, our restricted marketable investment securities, together with our restricted cash and cash equivalents, included amounts required as collateral for our letters of credit.

Other Investment Securities

We have strategic investments in certain debt and equity securities that are included in “Other noncurrent assets, net” on our Condensed Consolidated Balance Sheets and accounted for using the cost, equity and/or available-for-sale methods of accounting.

Our ability to realize value from our strategic investments in securities that are not publicly traded depends on 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.

Investment in Tracking Stock

On February 20, 2014, we entered into agreements with EchoStar to implement a transaction pursuant to which, among other things: (i) on March 1, 2014, we transferred to EchoStar and Hughes Satellite Systems Corporation (“HSSC”), a subsidiary of EchoStar, five satellites (EchoStar I, EchoStar VII, EchoStar X, EchoStar XI and EchoStar XIV (collectively the “Transferred Satellites”), including related in-orbit incentive obligations and cash interest payments of approximately $59 million), and approximately $11 million in cash in exchange for an aggregate of 6,290,499 shares of a series of preferred tracking stock issued by EchoStar and an aggregate of 81.128 shares of a series of preferred tracking stock issued by HSSC (collectively, the “Tracking Stock”); and (ii) beginning on March 1, 2014, we lease back certain satellite capacity on the Transferred Satellites (collectively, the “Satellite and Tracking Stock Transaction”). As of November 30, 2015, we no longer lease satellite capacity on the EchoStar I satellite. The Tracking Stock generally tracks the residential retail satellite broadband business of Hughes Network Systems, LLC (“HNS”), a wholly-owned subsidiary of HSSC, including without limitation the operations, assets and liabilities attributed to the Hughes residential retail satellite broadband business (collectively, the “Hughes Retail Group”). The shares of the Tracking Stock issued to us represent an aggregate 80% economic interest in the Hughes Retail Group.

Since the Satellite and Tracking Stock Transaction is among entities under common control, we recorded the Tracking Stock at EchoStar’s and HSSC’s historical cost basis for these instruments of $229 million and $87 million, respectively. The difference between the historical cost basis of the Tracking Stock received and the net carrying value of the Transferred Satellites of $356 million (including debt obligations, net of deferred taxes), plus the $11 million in cash, resulted in a $51 million capital transaction recorded in “Additional paid-in capital” on our Condensed Consolidated Balance Sheets. Although our investment in the Tracking Stock represents an aggregate 80% economic interest in the Hughes Retail Group, we have no operational control or significant influence over the Hughes Retail Group business, and currently there is no public market for the Tracking Stock. As such, the Tracking Stock is accounted for under the cost method of accounting.

On February 20, 2014, DISH Operating L.L.C. (“DOLLC”) and DISH Network L.L.C. (“DNLLC”), each indirect wholly-owned subsidiaries of us, entered into an Investor Rights Agreement with EchoStar and HSSC with respect to the Tracking Stock (the “Investor Rights Agreement”). The Investor Rights Agreement provides, among other things, certain information and consultation rights for us; certain transfer restrictions on the Tracking Stock and certain rights and obligations to offer and sell under certain circumstances (including a prohibition on transfers of the Tracking Stock for one year, with continuing transfer restrictions (including a right of first offer in favor of EchoStar) thereafter, an obligation to sell the Tracking Stock to EchoStar in connection with a change of control of DISH Network and a right to require EchoStar to repurchase the Tracking Stock in connection with a change of control of EchoStar, in each case subject to certain terms and conditions); certain registration rights; certain obligations to provide conversion and exchange rights of the Tracking Stock under certain circumstances; and certain protective covenants afforded to holders of the Tracking Stock. The Investor Rights Agreement generally will terminate with respect to our interest should we no longer hold any shares of the HSSC-issued Tracking Stock and any registrable securities under the Investor Rights Agreement.

Unrealized Gains (Losses) on Marketable Investment Securities

As of March 31, 2016 and December 31, 2015, we had accumulated net unrealized gains of less than $1 million and $20 million, respectively. These amounts, net of related tax effect, were less than $1 million and $12 million, respectively. All of these amounts are included in “Accumulated other comprehensive income (loss)” within “Total stockholder’s equity (deficit).” The components of our available-for-sale investments are summarized in the table below.

Actual maturities may differ from contractual maturities as a result of our ability to sell these securities prior to maturity.
