Senior Notes

In June 2020, $500 million of our 2.150% senior fixed rate notes matured and were repaid.

In June 2020, we issued additional senior unsecured notes in a reopening of our outstanding 1.900% fixed rate notes due 2025 and 2.700% fixed rate notes due 2030 that were issued in March 2020 in an aggregate principal amount of $750 million. The June 2020 issuance consisted of $300 million of additional 1.900% fixed rate notes due 2025 and $450 million of additional 2.700% fixed rate notes due 2030. We used a portion of these proceeds to complete a tender offer to purchase any and all of the $750 million aggregate principal amount of our 2.875% senior fixed rate notes due in 2021. We settled tender offers with holders of approximately 44% of the total outstanding principal amount of the 2.875% senior fixed rate notes due in 2021. Total cash consideration paid for these purchases was $339 million and the total carrying amount of the notes was $329 million, resulting in a loss on extinguishment of $10 million (including an immaterial amount of fees and other costs associated with the tender), which was recorded in interest and other, net in our condensed consolidated statement of income. In addition, we

paid any accrued interest on the tendered notes up to, but not including, the date of settlement.

Subsequent to June 30, 2020, we paid an additional $2 million to purchase additional 2.875% senior notes due 2021 upon final settlement of the tender offer. In July 2020, we exercised our option to redeem the remaining 2.875% senior notes due 2021 for an aggregate redemption price of approximately $419 million, plus accrued interest to the redemption date and a make-whole premium. The redemption is scheduled to settle in the third quarter.

In March 2020, we issued senior unsecured notes, or senior notes, in an aggregate principal amount of $1 billion. The issuance consisted of $500 million of 1.900% fixed rate notes due 2025 and $500 million of 2.700% fixed rate notes due 2030.

None of the floating rate notes are redeemable prior to maturity. On and after March 1, 2021, we may redeem some or all of the 6.000% fixed rate notes due 2056 at any time and from time to time prior to their maturity at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest. We may redeem some or all of the other fixed rate notes of each series at any time and from time to time prior to their maturity, generally at a make-whole redemption price, plus accrued and unpaid interest.

If a change of control triggering event (as defined in the applicable senior notes) occurs with respect to the 3.800% fixed rate notes due 2022, the floating rate notes due 2023, the 2.750% fixed rate notes due 2023, the 1.900% fixed rate notes due 2025, the 3.600% fixed rate notes due 2027, the 2.700% fixed rate notes due 2030 or the 6.000% fixed rate notes due 2056, we must, subject to certain exceptions, offer to repurchase all of the notes of the applicable series at a price equal to 101% of the principal amount, plus accrued and unpaid interest.

The indenture pursuant to which the senior notes were issued includes customary covenants that, among other things and subject to exceptions, limit our ability to incur, assume or guarantee debt secured by liens on specified assets or enter into sale and lease-back transactions with respect to specified properties, and also includes customary events of default with customary grace periods in certain circumstances, including payment defaults and bankruptcy-related defaults.

To help achieve our interest rate risk management objectives, in connection with the previous issuance of certain senior notes, we entered into interest rate swap agreements that effectively converted $2.4 billion of our fixed rate notes to floating rate debt based on LIBOR plus a spread. These swaps were designated as fair value hedges against changes in the fair value of certain fixed rate senior notes resulting from changes in interest rates. The gains and losses related to changes in the fair value of interest rate swaps substantially offset changes in the fair value of the hedged portion of the underlying debt that are attributable to changes in market interest rates. In 2019, $1.15 billion related to our 2.200% senior notes of the $2.4 billion aggregate notional amount matured. In addition, during 2019, we terminated the interest rate swaps related to $750 million of our 2.875% senior notes due July 2021 and $500 million of our 3.450% senior notes due July 2024. As a result of the early termination, hedge accounting was discontinued prospectively and the gain on termination was recorded as an increase to the long-term debt balance and is being recognized over the remaining life of the underlying debt as a reduction to interest expense. The gain recognized during the three and six months ended June 30, 2020 was immaterial.

To help achieve our interest rate risk management objectives, during the second quarter of 2020, we entered into interest rate swap agreements that effectively converted $400 million of our LIBOR-based floating-rate debt to a fixed-rate basis. These swaps were designated as cash flow hedges and have maturity dates in 2023.

The effective interest rates for our senior notes include the interest payable, the amortization of debt issuance costs and the amortization of any original issue discount and premium on these senior notes. Interest on these senior notes is payable either quarterly or semiannually. Interest expense associated with these senior notes, including amortization of debt issuance costs, was approximately $74 million and $79 million during the three months ended June 30, 2020 and 2019, respectively, and $144 million and $159 million during the six months ended June 30, 2020 and 2019, respectively.

As of June 30, 2020 and December 31, 2019, the estimated fair value of these senior notes, using Level 2 inputs, was approximately $9.2 billion and $7.9 billion, respectively.

Commercial Paper

We have a commercial paper program pursuant to which we may issue commercial paper notes in an aggregate principal amount at maturity of up to $1.5 billion outstanding at any time with maturities of up to 397 days from the date of issue. As of June 30, 2020, there were no commercial paper notes outstanding.

Credit Agreement

In March 2020, we entered into a credit agreement that provides for an unsecured $2 billion five-year credit facility. We may also, subject to the agreement of the applicable lenders, increase commitments under the revolving credit facility by up to $1 billion. Funds borrowed under the credit agreement may be used for working capital, capital expenditures, acquisitions and other general corporate purposes. The credit agreement replaced our prior $2 billion unsecured revolving credit agreement dated November 2015, which was terminated effective March 2020.

As of June 30, 2020, no borrowings were outstanding under our $2 billion credit agreement. However, as described above, we have an up to $1.5 billion commercial paper program and are required to maintain available borrowing capacity under our credit agreement in order to repay commercial paper borrowings in the event we are unable to repay those borrowings from other sources when they become due, in an aggregate amount of $1.5 billion. However as of June 30, 2020, no borrowings were outstanding under our commercial paper program; therefore, $2 billion of borrowing capacity was available for other purposes permitted by the credit agreement, subject to customary conditions to borrowing. The credit agreement includes a covenant limiting our consolidated leverage ratio to no more than 4.0:1.0, subject to, upon the occurrence of a qualified material acquisition, if so elected by us, a step-up to 4.5:1.0 for the four fiscal quarters completed following such qualified material acquisition. The credit agreement includes customary events of default, with corresponding grace periods in certain circumstances, including payment defaults, cross-defaults and bankruptcy-related defaults. In addition, the credit agreement contains customary affirmative and negative covenants, including restrictions regarding the incurrence of liens and subsidiary indebtedness, in each case, subject to customary exceptions. The credit agreement also contains customary representations and warranties.

We were in compliance with all covenants in our outstanding debt instruments during the six months ended June 30, 2020.
