The updated accounting guidance provides a single, contract-based revenue recognition model to help improve financial reporting by providing clearer guidance on when an entity should recognize revenue and by reducing the number of standards to which an entity has to refer. The updated guidance is effective for us as of January 1, 2018. The updated accounting guidance provides companies with alternative methods of adoption. We are currently in the process of determining the impact that the updated accounting guidance will have on our consolidated financial s tatements and our method of adoption. Consolidations In February 2015, the FASB updated the accounting guidance related to consolidation under the variable interest entity (“VIE”) and voting interest entity models. The updated accounting guidance modifies the consolidation guidance for VIEs, limited partnerships and similar legal entities. We have adopted this guidance as of January 1, 2016 and it did not have a material impact on our consolidated financial statements. Financial A ssets and Financial Liabili ties In January 2016, the FASB updated the accounting guidance related to the recognition and measurement of financial assets and financial liabilities. The updated accounting guidance, among other things, requires that all nonconsolidated equity investmen ts, except those accounted for under the equity method, be measured at fair value and that the changes in fair value be recognized in net income. The updated guidance is effective for us as of January 1, 2018. The updated accounting guidance requires a cum ulative effect adjustment to beginning retained earnings when the guidance is adopted with certain exceptions. We are currently in the process of determining the impact that the updated accounting guidance will have on our consolidated financial statements . Leases In February 2016, the FASB updated the accounting guidance related to leases. The updated accounting guidance requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short -term leases. For a lessee, the recognition, measurement and presentation of expenses and cash flows arising from a lease do not significantly change from previous guidance . For a lessor, the accounting applied is also largely unchanged from previous guida nce. The updated guidance is effective for us as of January 1, 2019 and early adoption is permitted. The updated accounting guidance must be adopted using a modified retrospective approach for leases that exist or are entered into after the beginning of th e earliest comparative period in the financial statements. We are currently in the process of determining the impact that the updated accounting guidance will have on our consolidated financial statements. Share-Based Compensation In March 2016, the FASB u pdated the accounting guidance that affects several aspects of the accounting for share-based compensation. The most significant change for us relates to the presentation of the income and withholding tax consequences of share-based compensation in our con solidated financial statements. Among the changes, the updated guidance requires that the excess income tax benefits or deficiencies that arise whe n the tax consequences of share- based compensation differ from amounts previously recognized in th e statement of income be recognized as income tax benefit or expense in the statement of income rather than as additional paid-in capital in the balance sheet. The guidance also states that excess income tax benefits should not be presented separately from other income taxes in the statement of cash flow s and, thus, should be classified as an operating activity rather than a financing activity as they are under the current guidance. In addition, the updated guidance requires when an employer withholds share s upon exercise of options or the vesting of restricted stock for the purpose of meeting withholding tax requirements, that the cash paid for withholding taxes be classified as a financing activity. We currently record these amounts within operating activi ties. We will implement the updated guidance in the first quarter of 2017. As required under the updated guidance, we will prospectively adopt the provisions of this guidance related to the recognition of the excess tax benefits or deficiencies in the statement of income. In addition, upon adoption we will retrospectively adopt the provisions of this guidance related to changes to the statement of cash flows for all periods presented. If we had adopted the provisions of the updated guidance as of Ja nuary 1, 2016, it would have increased net income attributab le to Comcast Corporation by $34 million and $193 million for the three and nine months ended September 30, 2016, respectively. In addition, the updated guidance would have increased net cash prov ided by operating activities and decreased net cash provided by (used in) financing activities by $ 493 million for the nine months ended September 30, 2016. The most significant impact of implementing the new guidance is expected to occur in the first quar ter of each year as a result of the vesting of restricted stock awards, which primarily occurs in March.

Among the changes, the updated guidance requires that the excess income tax benefits or deficiencies that arise whe n the tax consequences of share- based compensation differ from amounts previously recognized in the stat ement of income be recognized as income tax benefit or expense in the statement of income rather than as additional paid-in capital in the balance sheet. The guidance also states that excess income tax benefits should not be presented separately from other income taxes in the statement of cash flow s and, thus, should be classified as an operating activity rather than a financing activity as they are under the current guidance. In addition, the updated guidance requires when an employer withholds shares upon exercise of options or the vesting of restricted stock for the purpose of meeting withholding tax requirements, that the cash paid for withholding taxes be classified as a financing activity. We currently record these amounts within operating activities. We will implement the updated guidance in the first quarter of 2017 . As a limited liability company, we do not expect the updated accounting guidance related to the excess income tax benefits or deficiencies to be recognized in the statement of income to have an impact on our consolidated financial statements. In addition, we do not expect the updated accounting guidance to have a material impact on our statement of cash flows.

Significant Transactions	Note 4: Significant Transactions DreamWorks On August 22, 2016, we acquired all of the outstanding stock of DreamWorks Animation SKG, Inc. (“DreamWorks”) for $3.8 billion. DreamWorks’ stockholders received $41 in cash for each share of DreamWorks common stock. DreamWorks creates animated feature films, television series and specials, live entertainment and related consumer products. The results of operations for DreamWorks are reported in our Filmed Entertainment segment following the acquisition date. The transaction is accounted for under the acquisition method of accounting and, accordingly, the assets and liabilities are to be recorded at their fair market values as of the acquisiti on date . Due to the limited amount of time since the acquisition date, the assets and liabilities of DreamWorks were recorded based primarily on their historical carrying values. We recorded the debt we assumed from DreamWorks at its estimated fair value o f $381 million and we recorded a liability related to a tax receivable agreement that DreamWorks had previously entered into with one of its former stockholders (the “tax receivable agreement”) at its estimated fair value of $146 million. The fair value of the assumed debt was primarily based on quoted market values. The fair value of the tax receivable agreement was based on the contractual settlement provisions in the agreement and the value is subject to adjustment . In addition, we recorded deferred in come taxes based on our estimate of the tax basis of the acquired assets and valuation allowances based on the expected use of net operating loss carryforwards. The remaining assets and liabilities primarily consisted of goodwill and film and television co sts. We will adjust the remaining assets and liabilities to fair value and will record the related deferred income tax adjustments as valuations are completed and we obtain information necessary to complete the analyses, but no later than one year from the acquisition date. For purposes of the preliminary allocation of purchase price, the excess of the total transaction value over the recorded values of the net assets acquired has been recorded as goodwill. The tax receivable agreement was settled immediate ly following the acquisition and the payment was recorded as an operating activity in our condensed consolidated statement of cash flows. In addition, during the three months ended September 30, 2016, we repaid all of the assumed debt of DreamWorks (see No te 8). Revenue and net income attributable to the acquisition of DreamWorks were not material for the three and nine months ended September 30, 2016. During the three months ended September 30, 2016, we incurred severance costs of $50 million, which were r ecorded in operating costs and expenses in our Filmed Entertainment segment. Universal Studios Japan On November 13, 2015, NBCUniversal acquired a 51% economic interest in the Universal Studios theme park in Osaka, Japan (“Universal Studios Japan”) for $1.5 billion. Universal Studios Japan is a VIE based on the governance structure and we consolidate Universal Studios Japan as we have the power to direct activities that most significantly impact its economic performance. There are no liquidity arrangements, guarantees, or other financi al commitments between us and Universal Studios Japan, and therefore our maximum risk of financial loss is NBCUniversal’s 51% interest. Universal Studios Japan’s results of operations are reported in our Theme Parks segment following the acquisition date. Preliminary Allocation of Purchase Price The acquired assets and liabilities of Universal Studios Japan and the 49% noncontrolling interest were recorded at their estimated fair values. During the nine months ended September 30, 2016, we updated the prelim inary allocation of purchase price for Universal Studios Japan based on valuation analyses, which primarily resulted in increases to property and equipment and intangible assets and a decrease in goodwill. The changes did not have a material impact on our consolidated financial statements. We may adjust these amounts further as valuations are finalized and we obtain information necessary to complete the analyses, but no later than one year from the acquisition date.

Related Party Transactions	Note 4: Related Party Transactions In the ordinary course of our business, we enter into transactions with Comcast. We generate revenue from Comcast primarily from the distribution of our cable network programming , the fees received under retransmission consent agreements in our Broadcast Television segment and, to a lesser extent, the sale of advertising and our owned programming, and we incur expenses primarily related to advertising and various support services pr ovided by Comcast to us. In September 2016, as part of the Comcast cash management process, we and Comcast amended and restated our revolving credit agreements to increase the amount that we can borrow from Comcast and that Comcast can borrow from us from $3 billion to $5 billion and extend ed the maturity date to 2026. Amounts owed by us to Comcast or to us by Comcast under the revolving credit agreement, including accrued interest, are presented under the captio ns “note payable to Comcast” and “note receiv able from Comcast,” respectively, in our condensed consolidated balance sheet. The revolving credit agreements bear interest at floating rates equal to the interest rate calculation under Comcast’s revolving credit facility. The interest rate on Comcast’s revolving credit facility consists of a base rate plus a borrowing margin that is determined based on Comcast’s credit rating. As of September 30 , 2016, the borrowing margin for our London Interbank Offered Rate-based borrowings was 1.00%. Comcast is also the counterparty to one of our contractual obligations. As of September 30, 2016 , the carrying value of the liability associated with this contractual obligation was $ 383 million.

Following the close of the transaction, we continue to hold an investment in The Weather Channel cable network through a new holding company. As a result of the sale of our investment, we recognized a pretax gain for the nine months ended September 30, 2016 of $108 million in o ther income (expense), net. During the nine months ended September 30, 2015, The Weather Channel recorded an impairment charge related to goodwill. We recorded an expense of $252 million that represents NBCUniversal’s proportionate share of this impairmen t charge in equity in net income (losses) of investees, net in our condensed consolidated statement of income. Atairos In 2015, we entered into an agreement to establish Atairos Group, Inc. (“ Atairos ”), a strategic company focused on investing in and opera ting companies in a range of industries and business sectors, both domestically and internationally . The agreement became effective as of January 1, 2016. Atairos has a term of up to 12 years and is controlled by management companies led by our former CFO through interests that carry all of the voting rights. We are the only investor other than our former CFO and the other management company employees. We have committed to fund up to $4 billion in the aggregate at any one time in Atairos , subject to certain offsets, and $40 million annually to fund a management fee, subject to certain adjustments, while the management company investors have committed to fund up to $100 million (with at least $40 million to be funded by our former CFO, subject to his continue d role with Atairos ). Our economic interests do not carry voting rights and obligate us to absorb approximately 99% of any losses and provide us the right to receive approximately 86.5% of any residual returns in Atairos , in either case on a cumulative bas is. We have concluded that Atairos is a VIE, that we do not have the power to direct the activities that most significantly impact the economic performance of Atairos as we have no voting rights and only certain consent rights, and that we are not a relate d party with our former CFO or the management companies. We therefore do not consolidate Atairos and account for this investment as an equity method investment. There are no other liquidity arrangements, guarantees, or other financial commitments between C omcast and Atairos , and therefore our maximum risk of financial loss is our investment balance and remaining unfunded capital commitment. For the nine months ended September 30, 2016 , we made capital contributions totaling $ 399 million to Atairos . Hulu In August 2016, Time Warner Inc. acquired a 10% interest in Hulu, LLC (“Hulu”), which diluted our interest in Hulu from 33% to 30%. For a period not to exceed three years, Time Warner may put its sh ares to Hulu or Hulu may call Time Warner’s shares unde r certain limited circumstances arising from regulatory review. Given the contingent nature of the put and call options , we recorded a deferred gain of $159 million and a corresponding increase to our investment in Hulu as a result of the dilution. The deferred gain will be recognized in other income (expens e), net if and when the options expire unexercised. For the three and nine months ended September 30, 2016 , we recognized our proportionate share of losses of $ 43 million and $ 108 million, respectively, related to our investment in Hulu. For the three and nine months ended September 30, 2015 , we recognized our proportionate share of losses of $ 19 million and $ 43 million, respectively, related to our investment in Hulu. Cost Method AirTouch We hold two series of preferred stock of Verizon Americas, Inc., formerly known as AirTouch Communications, Inc. (“ AirTouch ”), a subsidiary of Verizon Communications Inc., which are redeemable in April 2020. As of September 30, 2016 , the estimated fair value of the AirTouch preferred stock and the estimated fair value of the associated liability related to the redeemable subsidiary preferred shares issued by one of our consolidated subsidiaries were each $ 1.7 billion. 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.

Given the contingent nature of the put and call options, we recorded a defe rred gain of $159 million and a corresponding increase to our investment in Hulu as a result of the dilution. The deferred gain will be recognized in other income (expense), net if and when the options expire unexercised. For the three and nine months ended September 30, 2016 , we recognized our proportionate share of losses of $ 43 million and $ 108 million, respectively, related to our investment in Hulu. For the three and nine months ended September 30, 2015 , we recognized our proportionate share of losses of $ 19 million and $ 43 million, respectively, related to our investment in Hulu.

Long-Term Debt	Note 8: Long-Term Debt As of September 30, 2016 , our debt had a carrying value of $ 60.4 billion and an estimated fair value of $ 69.4 billion. The estimated fair value of our publicly traded debt is primarily based on Level 1 inputs that use quoted market values for the debt. The estimated fair value of debt for which there are no quoted market prices is based on Level 2 inputs that use interest rates available to us for debt with similar terms and remaining maturities. Debt Borrowings and Repayments In July 2016, we issued $700 million aggregate principal amount of 1.625% senior notes due 2022, $1.4 billion aggregate principal amount o f 2.35% senior notes due 2027, $1.0 billion aggregate principal amount of 3.20% senior notes due 2036 and $1.4 billion aggregate principal amount of 3.40% senior notes due 2046. The proceeds from this offering were primarily used to fund our acquisition of DreamWorks. In May 2016, we issued $1.43 billion aggregate principal amount of 4.05% senior notes due 2046. In February and March 2016, we issued $1.1 billion aggregate principal amount of 2.75% senior notes due 2023 and $2.2 billion aggregate principal a mount of 3.15% senior notes due 2026. Following our acquisition of DreamWorks, we paid $381 million to settle all of the debt we assumed in the DreamWorks acquisition. In June 2016, we repaid at maturity $750 million aggregate principal amount of 4.95% se nior notes due 2016. In April 2016, we repaid at maturity $1 billion aggregate principal amount of 2.875% senior notes due 2016 and $700 million aggregate principal amount of NBCUniversal Enterprise Inc.’s (“NBCUniversal Enterprise”) senior notes due 2016. Revolvin g Credit Facilities In May 2016, we entered into a new $ 7 billion revolving credit facility due 2021 with a syndicate of banks (“Comcast revolving credit facility”) that may be used for general corporate purposes. We may increas e the commitment under the Comcast revolving credit facility up to a total of $10 billion, as well as extend the expiration date to a date no later than 2023, subject to approval of the lenders. In addition, NBCUniversal Enterprise entered into a new $ 1.5 billion revolving credit facility due 2021 with a syndicate of banks (“NBCUniversal Enterprise revolving credit facility”) that may be used for general corporate purposes . We may increase the commitment under the NBCUniversal Ente rprise revolving credit facility up to a total of $2 billion, as well as extend the expiration date to a date no late r than 2023, subject to approval of the lenders. The new revolving credit facilities replaced Comcast’s $6.25 billion and NBCUniversal Ente rprise’s $1.35 billion revolving credit facilities, which were terminated in connection with the execution of the new revolving credit facilities. The interest rates on the new revolving credit facilities consist of a base rate plus a borrowing margin that is determined based on Comcast’s credit rating. As of September 30, 2016 , the borrowing margin for borrowings based on the London Interbank Offered Rate was 1.00%. The terms of the new revolving credit facilities’ financial covenants and guarantees a re substantially the same as those under the prior revolving credit facilities.

Long-Term Debt	Note 8 : Long-Term Debt As of September 30, 2016 , our debt , excluding the note payable to Comcast, had a carrying value of $ 12.1 billion and an estimated fair value of $ 13.6 billion. The estimated fair value of our publicly traded debt is primarily based on Level 1 inputs that use quoted market values for the debt. The estimated fair value of debt for which there are no quoted market prices is based on Level 2 inputs that use interest rates available to us for debt with similar terms and remaining maturities. Debt Repayments Following Comcast’s acquisition of DreamWorks, we paid $381 million to settle all of the debt we assumed in the DreamWorks acquisition.

Fair Value Measurements	Note 9: Fair Value Measurements The accounting guidance related to financial assets and financial liabilities (“financial instruments”) establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). Level 1 consists of financial instruments whose values are based on quoted market prices for identical financial instruments in an active market. Level 2 consists of financi al instruments that are valued using models or other valuation methodologies. These models use inputs that are observable either directly or indirectly. Level 3 consists of financial instruments whose values are determined using pricing models that use sig nificant inputs that are primarily unobservable, discounted cash flow methodologies or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Our financial instruments th at are accounted for at fair value on a recurring basis are presented in the table below.

For both the three and nine months ended September 30, 2016 and 2015 , 2.8% of Cable Communications segment revenue was derived from franc hise and other regulatory fees. (b ) Beginning in the first quart er of 2016, certain operations and businesses, including several strategic business initiatives , that were previously presented in Corporate and Other are now presented in our Cable C ommunications segment to reflect a change in our management reporting presentation. For segment reporting purposes, we have adjusted all periods presented to reflect this change. (c) The revenue and operating costs and expenses associated with our broadcas t of the 2016 Rio Olympics were reported in our Cable Networks and Broadcast Television segments. The revenue and operating costs and expenses associated with our broadcast of the 2015 Super Bowl were reported in our Broadcast Television segment. (d) Begin ning in the fourth quarter of 2015, we changed our method of accounting for a contractual obligation that involves an interest in the revenue of certain theme parks. As a result of the change, amounts payable based on current period revenue are presented i n operating costs and expenses. Amounts paid through the third quarter of 2015 were included in other income (expense), net in our consolidated statement of income. For segment reporting purposes, we have adjusted periods prior to the fourth quarter of 201 5 to reflect management reporting presentation for this expense on a consistent basis for all periods in the Theme Parks segment and total NBCUniversal, which resulted in a corresponding offsetting adjustment in Eliminations to reconcile to consolidated to tals. (e) NBCUniversal Headquarters and Other activities include costs associated with overhead, personnel costs and headquarter initiatives. (f) Included in Eliminations are transactions that our segments enter into with one another. The most common types of transactions are the following: • our Cable Networks segment generates revenue by selling programming to our Cable Communications segment, which represents a substantial majority of the revenue elimination amount • our Broadcast Television segmen t generates revenue from the fees received under retransmission consent agreements with our Cable Communications segment • our Cable Communications segment generates revenue by selling advertising and by selling the use of satellite feeds to our Cable Netw orks segment • our Filmed Entertainment and Broadcast Television segments generate revenue by licensing content to our Cable Networks segment (g) No single customer accounted for a significant amount of revenue in any period. (h) We use operating income ( loss) before depreciation and amortization, excluding impairment charges related to fixed and intangible assets and gains or losses on the sale of assets, if any, as the measure of profit or loss for our operating segments. This measure eliminates the sign ificant level of noncash depreciation and amortization expense that results from the capital-intensive nature of certain of our businesses and from intangible assets recognized in business combinations. Additionally, it is unaffected by our capital structu re or investment activities. We use this measure to evaluate our consolidated operating performance and the operating performance of our operating segments and to allocate resources and capital to our operating segments. It is also a significant performanc e measure in our annual incentive compensation programs. We believe that this measure is useful to investors because it is one of the bases for comparing our operating performance with that of other companies in our industries, although our measure may not be directly comparable to similar measures used by other companies. This measure should not be considered a substitute for operating income (loss), net income (loss) attributable to Comcast Corporation, net cash provided by operating activities, or other measures of performance or liquidity we have reported in accordance with GAAP.

The revenue and operating costs and expenses associated with our broadcast of the 2015 Super Bowl were reported in our Broadcast Television segment. (b) Beginning in the fourth quarter of 2015, we changed our method of accounting for a contractual obligation that involves an interest in the revenue of certain theme parks. As a result of the change, amounts payable based on current period revenue are presented in operating costs and expenses. Amounts paid through the third quarter of 2015 were includ ed in other income (expense), net in our consolidated statement of income. For segment reporting purposes, we have adjusted periods prior to the fourth quarter of 2015 to reflect management reporting presentation for this expense on a consistent basis for all periods in the Theme Parks segment, which resulted in a corresponding offsetting adjustment in Eliminations to reconcile to consolidated totals. (c) Headquarters and Other activities include costs associated with overhead, personnel costs and headquar ter initiatives. (d) Included in Eliminations are transactions that our segments enter into with one another, which consist primarily of the licensing of film and television content from our Filmed Entertainment and Broadcast Television segments to our Ca ble Networks segment . (e) No single customer accounted for a significant amount of revenue in any period. (f) We use operating income (loss) before depreciation and amortization, excluding impairment charges related to fixed and intangible assets and gain s or losses on the sale of assets, if any, as the measure of profit or loss for our operating segments. This measure eliminates the significant level of noncash amortization expense that results from intangible assets recognized in business combinations. A dditionally, it is unaffected by our capital structure or investment activities. We use this measure to evaluate our consolidated operating performance and the operating performance of our operating segments and to allocate resources and capital to our ope rating segments. It is also a significant performance measure in our annual incentive compensation programs. We believe that this measure is useful to investors because it is one of the bases for comparing our operating performance with that of other compa nies in our industries, although our measure may not be directly comparable to similar measures used by other companies. This measure should not be considered a substitute for operating income (loss), net income (loss) attributable to NBCUniversal, net cas h provided by operating activities, or other measures of performance or liquidity we have reported in accordance with GAAP.
