Short-Term Borrowings and Borrowing Arrangements	Short-Term Borrowings and Borrowing Arrangements At December 31, 2019, Altria had no short-term borrowings. At December 31, 2018, Altria had $12.7 billion of short-term borrowings, which was net of approximately $95 million of debt issuance costs, under the term loan agreement discussed below. In December 2018, Altria entered into a senior unsecured term loan agreement in connection with its investments in JUUL and Cronos (the “Term Loan Agreement”). At December 31, 2018, Altria had aggregate short-term borrowings under the Term Loan Agreement of $12.8 billion at an average interest rate of approximately 3.5%. Borrowings under the Term Loan Agreement were set to mature on December 19, 2019. In February 2019, Altria repaid all of the outstanding $12.8 billion of short-term borrowings under the Term Loan Agreement with net proceeds from the issuance of long-term senior unsecured notes. See Note 10. Long-Term Debt. Upon repayment, the Term Loan Agreement terminated in accordance with its terms. In 2019, Altria recorded approximately $95 million of pre-tax acquisition-related costs for the write-off of the debt issuance costs related to the Term Loan Agreement, which were recorded in interest and other debt expense, net in Altria’s consolidated statement of earnings (losses). Altria’s estimate of the fair value of its short-term borrowings is derived from discounted future cash flows based on the contractual terms of the Term Loan Agreement and observable interest rates and is classified in Level 2 of the fair value hierarchy. The fair value of Altria’s short-term borrowings at December 31, 2018 approximated its carrying value. At December 31, 2018, accrued interest on short-term borrowings of $15 million was included in other accrued liabilities on Altria’s consolidated balance sheet. At December 31, 2019, Altria had a senior unsecured 5-year revolving credit agreement (the “Credit Agreement”). The Credit Agreement, which is used for general corporate purposes, provides for borrowings up to an aggregate principal amount of $3.0 billion. The Credit Agreement expires on August 1, 2023 and includes an option, subject to certain conditions, for Altria to extend the Credit Agreement for two additional one-year periods. Pricing for interest and fees under the Credit Agreement may be modified in the event of a change in the rating of Altria’s long-term senior unsecured debt. Interest rates on borrowings under the Credit Agreement are expected to be based on the London Interbank Offered Rate (“LIBOR”), or a mutually agreed upon benchmark rate, plus a percentage based on the higher of the ratings of Altria’s long-term senior unsecured debt from Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s Ratings Services (“Standard & Poor’s”). The applicable percentage based on Altria’s long-term senior unsecured debt ratings at December 31, 2019 for borrowings under the Credit Agreement was 1.0%. The Credit Agreement does not include any other rating triggers, or any provisions that could require the posting of collateral. At December 31, 2019 and 2018, Altria had no borrowings under the Credit Agreement. The credit line available to Altria at December 31, 2019 under the Credit Agreement was $3.0 billion. The Credit Agreement includes various covenants, one of which requires Altria to maintain a ratio of consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) to Consolidated Interest Expense of not less than 4.0 to 1.0, calculated as of the end of the applicable quarter on a rolling four quarters basis. At December 31, 2019, the ratio of consolidated EBITDA to Consolidated Interest Expense, calculated in accordance with the Credit Agreement, was 8.2 to 1.0. At December 31, 2019, Altria was in compliance with its covenants in the Credit Agreement. The terms “Consolidated EBITDA” and “Consolidated Interest Expense,” each as defined in the Credit Agreement, include certain adjustments. Any commercial paper issued by Altria and borrowings under the Credit Agreement are guaranteed by PM USA as further discussed in Note 20. Condensed Consolidating Financial Information.
