Long-Term Debt	Jun. 30, 2016
Long-Term Debt	Note 8: Long-Term Debt As of June 30, 2016, our debt had a carrying value of $55.6 billion and an estimated fair value of $64.4 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 of 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.

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 amount of 3.15% senior notes due 2026.

Revolving 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 increase 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 Enterprise revolving credit facility up to a total of $2 billion, as well as extend the expiration date to a date no later than 2023, subject to approval of the lenders. The new revolving credit facilities replaced Comcast’s $6.25 billion and NBCUniversal Enterprise’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 June 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 are substantially the same as those under the prior revolving credit facilities. As of June 30, 2016, amounts available under the new consolidated revolving credit facilities, net of amounts outstanding under our commercial paper programs and outstanding letters of credit, totaled $7.1 billion, which included $326 million available under NBCUniversal Enterprise’s revolving credit facility.
