Significant Transactions	Note 5: Significant Transactions 2014 Time Warner Cable Merger On February 12, 2014, we entered into the merger agreement with Time Warner Cable. Time Warner Cable is among the largest providers of video, high-speed Internet and voice services in the United States, located mainly in five geographic areas: New York State (including New York City), the Carolinas, the Midwest (including Ohio, Kentucky and Wisconsin), Southern California (including Los Angeles) and Texas. Time Warner Cable stockholders will receive, in exchange for each share of Time Warner Cable common stock owned immediately prior to the Time Warner Cable merger, 2.875 shares of our Class A common stock. Because the exchange ratio was fixed at the time of the merger agreement and the market value of our Class A common stock will continue to fluctuate, the number of shares of Class A common stock to be issued and the total value of the consideration exchanged will not be determinable until the closing date. The Time Warner Cable merger was approved by both Comcast shareholders and Time Warner Cable stockholders in October 2014. The Time Warner Cable merger remains subject to regulatory approval and other customary conditions and is expected to close in early 2015. Divestiture Transactions The terms of the merger agreement contemplated that we would divest systems serving up to approximately 3 million of our video customers following the Time Warner Cable merger in order to obtain applicable regulatory approvals. As a result of this commitment, on April 25, 2014, we entered into an agreement with Charter that, if consummated, would satisfy the divestiture undertaking. Under this agreement, following the close of the Time Warner Cable merger and subject to various conditions, we agreed to divest certain cable systems through three transactions: (1) a spin-off of certain of our existing cable systems (the “spin-off transaction”) into a newly formed public entity (“SpinCo”), (2) an exchange of certain former Time Warner Cable cable systems for Charter cable systems, and (3) a sale to Charter of certain former Time Warner Cable cable systems for cash (collectively, the “divestiture transactions”). In connection with and prior to the spin-off transaction, it is expected that SpinCo would incur new debt. The debt would consist of credit facilities to fund cash distributions to us and notes which SpinCo would issue to us. These notes would enable us to complete a debt-for-debt exchange where financial institutions would exchange a portion of our debt securities for the new SpinCo notes, which would effectively retire a portion of our debt. In the spin-off transaction, we would distribute the common stock of SpinCo pro rata to the holders of all of our outstanding common stock as of the record date, which would occur following the close of the Time Warner Cable merger. After the spin-off transaction, a newly formed, wholly owned indirect subsidiary of Charter would merge with and into Charter with the effect that all shares of Charter would be converted into shares of a new holding company, which would survive as the publicly traded parent company of Charter (“New Charter”). New Charter would then acquire an interest in SpinCo by issuing New Charter stock in exchange for a portion of the outstanding SpinCo stock, following which it is expected that Comcast shareholders would own approximately 67% of SpinCo and New Charter would own approximately 33% of SpinCo. In addition, Comcast shareholders would own New Charter stock as a result of the exchange of outstanding SpinCo stock with New Charter, although the actual number of shares would depend on a number of factors, some of which would not be determinable until the completion of the divestiture transactions. Following the close of the divestiture transactions, we would no longer have any ownership interest in SpinCo. The close of the divestiture transactions is subject to the completion of the Time Warner Cable merger, the SpinCo financing transactions, approval by Charter’s stockholders, regulatory approvals and other customary conditions. The Time Warner Cable merger and the divestiture transactions are subject to separate conditions, and the Time Warner Cable merger can be completed regardless of whether the divestiture transactions are ultimately completed. The closing of the divestiture transactions is expected to occur 30 to 60 days following the close of the Time Warner Cable merger. Transactions-Related Expenses In connection with the Time Warner Cable merger and the divestiture transactions, we have incurred incremental expenses of $237 million in 2014 which included legal, accounting and valuation services and advisory fees, all of which are reflected in other operating and administrative expenses. 2013 NBCUniversal Redemption Transaction On March 19, 2013, we acquired GE’s 49% common equity interest in NBCUniversal Holdings that we did not already own for approximately $16.7 billion (the “NBCUniversal redemption transaction”). In addition to the NBCUniversal redemption transaction, NBCUniversal purchased from GE certain properties NBCUniversal occupies at 30 Rockefeller Plaza in New York City and CNBC’s headquarters in Englewood Cliffs, New Jersey for $1.4 billion. The total consideration for these transactions consisted of $11.4 billion of cash on hand; $4 billion of senior debt securities issued by NBCUniversal Enterprise, Inc. (“NBCUniversal Enterprise”), a holding company that we control and consolidate following the close of the NBCUniversal redemption transaction whose principal assets are its interests in NBCUniversal Holdings; $750 million of cash funded through our commercial paper program; $1.25 billion of borrowings under NBCUniversal Enterprise’s credit facility, which replaced NBCUniversal’s credit facility; and $725 million aggregate liquidation preference of Series A cumulative preferred stock of NBCUniversal Enterprise. See Note 20 for additional information on our cross-guarantee structure. Because we maintained control of NBCUniversal Holdings, the difference between the consideration transferred and the recorded value of GE’s 49% redeemable noncontrolling common equity interest, and the related tax impacts, were recorded to additional paid-in capital. The NBCUniversal Enterprise preferred stock pays dividends at a fixed rate of 5.25% per annum. The holders have the right to cause NBCUniversal Enterprise to redeem their shares at a price equal to the liquidation preference plus accrued but unpaid dividends for a 30 day period beginning on March 19, 2020 and thereafter on every third anniversary of such date (each such date, a “put date”). Shares of preferred stock can be called for redemption by NBCUniversal Enterprise at a price equal to the liquidation preference plus accrued but unpaid dividends one year following each put date applicable to such shares. Because certain of these redemption provisions are outside of our control, the NBCUniversal Enterprise preferred stock is presented outside of equity under the caption “redeemable noncontrolling interests and redeemable subsidiary preferred stock” in our consolidated balance sheet. Its initial value was based on the liquidation preference of the preferred stock and is adjusted for accrued but unpaid dividends. As of December 31, 2014 and 2013, the fair value of the NBCUniversal Enterprise redeemable subsidiary preferred stock was $751 million and $741 million, respectively. The estimated fair values are based on Level 2 inputs that use pricing models whose inputs are derived primarily from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument.

Significant Transactions	Note 4: Significant Transactions 2013 Redemption Transaction On March 19, 2013, Comcast acquired GE’s 49% common equity interest in NBCUniversal Holdings that it did not already own for approximately $16.7 billion (the “redemption transaction”). In addition to the redemption transaction, we purchased from GE certain properties we occupy at 30 Rockefeller Plaza in New York City and CNBC’s headquarters in Englewood Cliffs, New Jersey for $1.4 billion. The total consideration for these transactions consisted of $11.4 billion of cash on hand (of which we funded $4.6 billion); $4 billion of senior debt securities issued by NBCUniversal Enterprise, Inc. (“NBCUniversal Enterprise”), a holding company whose principal assets are its interests in NBCUniversal Holdings; $750 million of cash funded through Comcast’s commercial paper program; $1.25 billion of borrowings under NBCUniversal Enterprise’s credit facility, which replaced our credit facility; and $725 million aggregate liquidation preference of Series A cumulative preferred stock of NBCUniversal Enterprise. After the close of the transaction, GE sold the interests in NBCUniversal Enterprise’s senior debt securities and preferred stock it acquired in the redemption transaction to unaffiliated third parties. Following the close of the redemption transaction, Comcast owns 96% of NBCUniversal Holdings’ common units and NBCUniversal Enterprise owns the remaining 4%. NBCUniversal Enterprise is now a consolidated subsidiary of Comcast, but we do not have any ownership interests in NBCUniversal Enterprise. NBCUniversal Enterprise also owns all of NBCUniversal Holdings’ preferred units with a $9.4 billion aggregate liquidation preference. NBCUniversal Holdings is required to make quarterly payments to NBCUniversal Enterprise at an initial rate of 8.25% per annum on the $9.4 billion aggregate liquidation preference of the preferred units. On March 1, 2018, and thereafter on every fifth anniversary of such date, this rate will reset to 7.44% plus the yield on actively traded United States Treasury securities having a 5 year maturity. NBCUniversal Holdings has the right to redeem all of the preferred units during the 30 day period beginning on March 1, 2018, and NBCUniversal Enterprise has the right to cause NBCUniversal Holdings to redeem 15% of its preferred units during the 30 day period beginning on March 19, 2020. The price and units in a redemption initiated by either party will be based on the liquidation preference plus accrued but unpaid dividends and adjusted, in the case of an exercise of NBCUniversal Enterprise’s right, to the extent the equity value of NBCUniversal Holdings is less than the liquidation preference. Our cash flows are, and will continue to be, the primary source of funding for the required payments and for any future redemption of the NBCUniversal Holdings preferred units.

2013

NBCUniversal Redemption Transaction

On March 19, 2013, we acquired GE’s 49% common equity interest in NBCUniversal Holdings that we did not already own for approximately $16.7 billion (the “NBCUniversal redemption transaction”). In addition to the NBCUniversal redemption transaction, NBCUniversal purchased from GE certain properties NBCUniversal occupies at 30 Rockefeller Plaza in New York City and CNBC’s headquarters in Englewood Cliffs, New Jersey for $1.4 billion.

The total consideration for these transactions consisted of $11.4 billion of cash on hand; $4 billion of senior debt securities issued by NBCUniversal Enterprise, Inc. (“NBCUniversal Enterprise”), a holding company that we control and consolidate following the close of the NBCUniversal redemption transaction whose principal assets are its interests in NBCUniversal Holdings; $750 million of cash funded through our commercial paper program; $1.25 billion of borrowings under NBCUniversal Enterprise’s credit facility, which replaced NBCUniversal’s credit facility; and $725 million aggregate liquidation preference of Series A cumulative preferred stock of NBCUniversal Enterprise. See Note 20 for additional information on our cross-guarantee structure.

Because we maintained control of NBCUniversal Holdings, the difference between the consideration transferred and the recorded value of GE’s 49% redeemable noncontrolling common equity interest, and the related tax impacts, were recorded to additional paid-in capital.

The NBCUniversal Enterprise preferred stock pays dividends at a fixed rate of 5.25% per annum. The holders have the right to cause NBCUniversal Enterprise to redeem their shares at a price equal to the liquidation preference plus accrued but unpaid dividends for a 30 day period beginning on March 19, 2020 and thereafter on every third anniversary of such date (each such date, a “put date”).

2013

Redemption Transaction

On March 19, 2013, Comcast acquired GE’s 49% common equity interest in NBCUniversal Holdings that it did not already own for approximately $16.7 billion (the “redemption transaction”). In addition to the redemption transaction, we purchased from GE certain properties we occupy at 30 Rockefeller Plaza in New York City and CNBC’s headquarters in Englewood Cliffs, New Jersey for $1.4 billion.

After the close of the transaction, GE sold the interests in NBCUniversal Enterprise’s senior debt securities and preferred stock it acquired in the redemption transaction to unaffiliated third parties.

Following the close of the redemption transaction, Comcast owns 96% of NBCUniversal Holdings’ common units and NBCUniversal Enterprise owns the remaining 4%.
