|Debt Disclosure [Abstract]|
Revolving Credit Facility. We have an Amended and Restated Revolving Credit Facility (Revolving Credit Facility) that provides for unsecured revolving facility loans, swing line loans and letters of credit in an aggregate amount of up to $5.0 billion, of which $530 million and $4.47 billion will expire in February 2020 and November 2021, respectively. Proceeds from the Revolving Credit Facility, if drawn, are expected to be used for general corporate purposes. Loans under the Revolving Credit Facility will bear interest, at our option, at either the reserve-adjusted Eurocurrency Rate (determined in accordance with the Revolving Credit Facility) or the Base Rate (determined in accordance with the Revolving Credit Facility), in each case plus an applicable margin based on our long-term unsecured senior, non-credit enhanced debt ratings. The margins over the reserve-adjusted Eurocurrency Rate and the Base Rate will be 0.805% and 0.00% per annum, respectively. The Revolving Credit Facility has a facility fee, which accrues at a rate of 0.07% per annum. At March 31, 2019 and September 30, 2018, we had not borrowed any funds under the Revolving Credit Facility.
Commercial Paper Program. We have an unsecured commercial paper program, which provides for the issuance of up to $5.0 billion of commercial paper. Net proceeds from this program are used for general corporate purposes. Maturities of commercial paper can range from 1 day to up to 397 days. At March 31, 2019 and September 30, 2018, we had $1.0 billion of outstanding commercial paper included in short-term debt with a weighted-average interest rate of 2.74% and 2.35%, respectively, which included fees paid to the commercial paper dealers, and weighted-average remaining days to maturity of 29 days and 16 days, respectively. The carrying value of the outstanding commercial paper approximated its estimated fair value at March 31, 2019 and September 30, 2018.
Long-term Debt. The following table provides a summary of our long-term debt (in millions, except percentages):
At March 31, 2019 and September 30, 2018, the aggregate fair value of the notes, based on Level 2 inputs, was approximately $15.4 billion and $15.1 billion, respectively.
We may redeem the outstanding fixed-rate notes at any time in whole, or from time to time in part, at specified make-whole premiums as defined in the applicable form of note. We may not redeem the outstanding floating-rate notes prior to maturity. The obligations under the notes rank equally in right of payment with all of our other senior unsecured indebtedness and will effectively rank junior to all liabilities of our subsidiaries.
At March 31, 2019, we had outstanding interest rate swaps with an aggregate notional amount of $1.8 billion related to the May 2015 Notes, which effectively converted approximately 43% and 50% of the fixed-rate notes due in 2020 and 2022, respectively, into floating-rate notes. The net gains and losses on the interest rate swaps, as well as the offsetting gains or losses on the related fixed-rate notes attributable to the hedged risks, are recorded as interest expense in the current period. We did not enter into interest rate swaps in connection with issuance of the May 2017 Notes.
The effective interest rates for the notes include the interest on the notes, amortization of the discount, which includes debt issuance costs, and if applicable, adjustments related to hedging. Interest is payable in arrears quarterly for the floating-rate notes and semi-annually for the fixed-rate notes. Cash interest paid related to our commercial paper program and long-term debt, net of cash received from the related interest rate swaps, was $281 million and $317 million in the six months ended March 31, 2019 and March 25, 2018, respectively.
Debt Covenants. The Revolving Credit Facility requires that we comply with certain covenants, including one financial covenant to maintain a ratio of consolidated earnings before interest, taxes, depreciation and amortization to consolidated interest expense, as defined in each of the respective agreements, of not less than three to one at the end of each fiscal quarter. We are not subject to any financial covenants under the notes nor any covenants that would prohibit us from incurring additional indebtedness ranking equal to the notes, paying dividends, issuing securities or repurchasing securities issued by us or our subsidiaries. At March 31, 2019 and September 30, 2018, we were in compliance with the applicable covenants under the Revolving Credit Facility.
The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
